Condensers are often used in reflux, where the hot solvent vapors of a liquid being heated are cooled and allowed to drip back. This reduces the loss of solvent allowing the mixture to be heated for extended periods. Condensers are used in distillation to cool the hot vapors, condensing them into liquid for separate collection. For fractional distillation, an air or Vigreux condenser is usually used to slow the rate at which the hot vapors rise, giving a better separation between the different components in the distillate. For microscale distillation, the apparatus includes the pot, and the condenser fused into one piece, which reduces the holdup volume, and obviates the need for ground glass joints preventing contamination by grease and precluding leaks.
The simplest sort of condenser consists of a single tube wherein the heat of the vapour is conducted to the glass wall, which is only cooled by air; such "air condensers" are often used for condensation of high boiling liquids (for distillations at high temperatures, well above 100 °C), where columns can be used with or without packing (see below). Historically, the retort appearing in illustrations of the practice of alchemists is an apparatus that is essentially an unpacked air condenser. Liebig condensers are often used as air condensers, with air circulated rather than a liquid coolant (see next section).
A "Vigreux column", named after the French glass blower (1869–1951), is a type of air condenser in which a glass blower has modified the simple tube to include an abundance of downward-pointing indentations, thus dramatically increasing the surface area per unit length of the condenser; the Vigreux column was invented in 1904. Such columns are often used to add the theoretical plates required in fractional distillation, and present added cost for their manufacture, which can include designs with or without an outer glass cylinder (jacket), open to air or allowing fluid circulation, or, to aid in insulation, an outer vacuum jacket.
A "Snyder column" is an extremely effective air-cooled column used in selected fractional distillations. It is a single glass tube with a series of circular indentations or restrictions in the walls of the cylinder (often 3 or 6) in which rest, inverted, the same number of roughly tear-shaped, hollow, sealed glass stoppers; above each point where an inverted tear-shaped stopper rests, the cylinder has further Vigreux-type indentations, in this case serving to limit how high the glass stopper can be raised (by vapor flow) above its resting place, where, when not raised, it seals the circular opening created by the circular indentation. These floating glass stoppers act as check valves, closing and opening with vapor flow, and enhancing vapor-condensate mixing. A standard application of Snyder columns, is as the condenser and fractionation column above a Kuderna-Danish concentrator, used to efficiently separate a low boiling extraction solvent such as methylene chloride from volatile but higher boiling extract components (e.g., after the extraction of organic contaminants in soil).
A further air condenser is the "Widmer column", developed as a doctoral research project by student Gustav Widmer at ETH Zurich in the early 1920s, a complex type of air condenser combining Golodetz-type concentric tubes and the Dufton-type glass rod-and-wound-spiral at its center (see image).
The condenser known as the Liebig type, a most basic circulating fluid-cooled design, was invented by several investigators working independently; however, the earliest laboratory condenser was invented in 1771 by the Swedish-German chemist Christian Weigel (1748–1831). Weigel’s condenser consisted of two coaxial tin tubes, which were joined at their lower ends and open at their upper ends. Cold water entered, via an inlet, the lower end of this jacket and spilled out of the jacket’s open upper end. A glass tube carrying vapors from a distillation flask passed through the inner tin tube, not in contact with the cooling water. Weigel subsequently replaced the inner tin tube with a glass tube, and he devised a clamp to hold the condenser. In 1791, the German chemist Johann Friedrich August Göttling (1753–1809), who was a former student of Weigel, sealed both ends of Weigel's condenser. The German chemist Justus Liebig (1803–1873) eliminated the inner wall of Weigel’s condenser, placing, in direct contact with the jacket’s cooling water, the glass tube carrying vapors from the distillation flask. He also replaced, with glass, the outer metal wall of Weigel’s condenser. And he used rubber hoses, instead of metal tubes, to convey water to and from the condenser.
The design popularized by Liebig thus consisted of an inner, straight tube surrounded by an outer straight tube, with the outer tube having ports for fluid inflow and outflow, and with the two tubes sealed in some fashion at the ends (eventually, by a blown glass "ring seal"). Its simplicity made it convenient to construct and inexpensive to manufacture, the higher heat capacity of the circulating water (versus air) allowed for maintaining near to constant temperature in the condenser, and so the Liebig type proved to be the more efficient condenser—capable of condensing liquid from a much greater flow of incoming vapor—and therefore replaced retorts and air condensers. An added benefit of the simplicity of the straight inner tube design of this condenser type is that it can be "packed" with materials that increase the surface area (and so the number of theoretical plates of the distillation column, see section below), e.g., plastic, ceramic, and metal beads, rings, wool, etc. See Fractional Distillation.
A variant of the Liebig condenser having a more slender design, with cone and socket. The fused-on narrower coolant jacket may render more efficient cooling with respect to coolant consumption.
The Allihn condenser or "bulb condenser" or simply "reflux condenser" is named after Felix Richard Allihn (1854–1915). The Allihn condenser consists of a long glass tube with a water jacket. A series of bulbs on the tube increases the surface area upon which the vapor constituents may condense. Ideally suited for laboratory-scale refluxing.
A Davies condenser, also known as a double surface condenser, is similar to the Liebig condenser, but with three concentric glass tubes instead of two. The coolant circulates in both the outer jacket and the central tube. This increases the cooling surface, so that the condenser can be shorter than an equivalent Liebig condenser.
A Graham condenser (also called "Grahams" or "Inland Revenue" condenser) has a coolant-jacketed spiral coil running the length of the condenser serving as the vapor–condensate path. This is not to be confused with the coil condenser. The coiled condenser tubes inside will provide more surface area for cooling and for this reason it is most favorable to use but the drawback of this condenser is that as the vapors get condensed, it tends to move them up in the tube to evaporate which will also lead to the flooding of solution mixture.
A coil condenser is essentially a Graham condenser with an inverted coolant–vapor configuration. It has a spiral coil running the length of the condenser through which coolant flows, and this coolant coil is jacketed by the vapor–condensate path.
A Dimroth condenser, named after Otto Dimroth, is somewhat similar to the coil condenser; it has an internal double spiral through which coolant flows such that the coolant inlet and outlet are both at the top. The vapors travel through the jacket from bottom to top. Dimroth condensers are more effective than conventional coil condensers. They are often found in rotary evaporators.
A spiral condenser has a spiral condensing tube with both inlet and outlet connections at the top, and on the same side. See Dimroth condenser.
A Friedrichs condenser (sometimes incorrectly referred to as "Friedrich's" condenser), a spiraled finger condenser, was invented by Fritz Walter Paul Friedrichs, who published a design for this type of condenser in 1912. It consists of a large, spiraled internal cold finger-type capillary tube disposed within a wide cylindrical housing. Coolant flows through the internal cold finger; accordingly, vapors rising up through the housing must pass along the spiraled path.
During a fractional distillation in the laboratory (or chemical plant), simple straight tubes can be packed with materials to increase surface area, and therefore the number of theoretical plates; in the same manner, the surface areas of simple laboratory glass condensers such as the Liebig can be filled to improve performance. The same standard distillation packing materials can be used—glass beads, rings, or helices (such as Fenske rings), "porcelain" Raschig or Lessing rings, or metal packings of aluminum, copper, nickel, and stainless steel of most of the preceding shapes (such as metal Lessing and Fenske types); glass packings have as a further benefit their chemical inertness relevant to distillations of reactive chemicals (like acid chlorides), while metal packings are easier to tamp to "ensure uniform Packing".
Metal packing types can extend to wire packings of nichrome and inconel (akin to Podbielniak columns), to stainless steel gauze (Dixon rings), and indeed to any of the various special packing methods used in distillation (e.g., Hempel, Todd, and Stedman packing methods); for instance, wire-packed columns of the Podbielniak type function by providing large surface areas for vapor-liquid interaction with capillary-like spaces that very evenly spread the condensed liquid, such that "channeling and flooding" in the column "are minimized", and giving, in one specific example, added theoretical plate counts of 1–2 per 5 cm of packed length.
Solid dry ice or an acetone/dry ice mixture can be used in a cold finger as a coolant, which allows cooling of the vapour stream to below 0 °C, a matter critical in the condensation of low boiling liquids (such as dimethyl ether, −23.6 °C). Likewise, other chilled liquids can be circulated through typical water-cooled condensers; circulating coolants include water–ethylene glycol cosolvents (antifreeze solutions), and pure liquids such as ethanol, in either case pumped in a closed loop (recycling) fashion from a chiller-circulator under thermostatic control.

= = = Jiggs Donahue = = =
John Augustine Donahue (July 13, 1879 – July 19, 1913) was an American Major League Baseball first baseman and catcher with the Pittsburgh Pirates, Milwaukee Brewers / Baltimore Orioles, St. Louis Browns, Chicago White Sox and the Washington Senators between 1900 and 1909. Donahue was born in Springfield, Ohio. He batted and threw left-handed.
Donahue had his greatest success from 1904 to 1908, after switching to first base for the Chicago White Sox. Donahue's defensive skills were a key to the White Sox' 1906 World Series championship team, and he led American League first basemen in fielding percentage, assists, and putouts for 3 consecutive seasons, from 1905 to 1907. In 1907, Donahue had 1,846 putouts, which is still the major league record for putouts by a first baseman. He also holds the major league single season record for most chances accepted per game with 12.65 in 1907.
Though known mostly for his fielding, Donahue was also a decent hitter from 1905 to 1907. In 1905, he was among the American League leaders in batting average (.287), on-base percentage (.346), RBIs (76), and stolen bases (32). In 1906, Donahue was among the league leaders in stolen bases (36) and sacrifice hits (36) and was one of only three White Sox starters to bat over .250 for the 1906 World Champion "Hitless Wonders." Donahue hit for a .278 average (5-for-18) with 2 doubles, 1 triple and 4 RBI.
On October 10, 1906, Donahue broke up a World Series no-hit bid by Cubs' pitcher Ed Reulbach with a single in the 7th inning.
In 1907, Donahue led the league in games played (157) and at bats (609) and was among the leaders in hits (158) and RBIs (68).
In Detroit on May 31, 1908, Donahue recorded 21 putouts in a nine-inning game.
In 9 seasons, Donahue played in 813 games with 731 hits, 319 runs scored, 327 RBIs, 143 stolen bases, 90 doubles, 31 triples, and a .255 batting average.
Donahue contracted syphilis and died in 1913 at age 34. He was survived by a brother, Pat Donahue, a major league catcher in the years 1908-10.
= = = Hanstead House = = =
Hanstead House or Hanstead Park is a country house estate in Hertfordshire, England. Hanstead is near Bricket Wood, about three miles from Radlett and five miles from St Albans, within the green belt around London. It forms part of the civil parish of St Stephen, Hertfordshire within St Albans District Council. The park has been a stud, a college, and a corporate training centre, and is now owned by a property development firm. The current building, though in the Georgian style, dates from 1925. The property was mentioned in the Domesday Book.
The house was built for the Yule family. Sir David Yule (1858–1928) was a Scottish entrepreneur who went into the family business, which was trade with India, then the "jewel in the crown" of the British Empire. He was involved with many additional businesses. The "Oxford Dictionary of National Biography" judged him "arguably the most important businessman in India" and quoted his obituary in "The Times" as "one of the wealthiest men, if not the wealthiest man, in the country".
A later owner of the property wrote: "In 1925 Sir David decided to build for himself a mansion on this 1200 acre [4.9 km²] estate, located only five miles [8 km] from the northwest edge of London. Prior to this he had built a 'modest' two-story house of some 14 rooms to live in during construction of the mansion. It was later to become the guest house."
Yule had married his cousin Annie Henrietta, oldest daughter of his uncle Andrew Yule of Calcutta. They had one child, Gladys. He died only three years after the construction of the house, and "lies buried in an admirably designed carved stone tomb, covered overhead by a stone and wood canopy, enclosed by an ornate iron fence inside a small wooded park, the whole being encircled by another iron fence." The Mausolea and Monuments Trust says that the sculpture itself is a draped chair with inscription from Kipling's "Jungle Book" and a box tomb showing his Indian jute mills and plantations.
The two women lived the rest of their lives at Hanstead. The new main house became the home of the daughter, while her mother lived in the guest house (see dower house). They were world travellers who reportedly shared an interest in big game hunting and a love of animals. Hanstead House was said to have been adorned by a large stuffed bear which they had killed in the Rocky Mountains of Colorado. On the grounds they kept a seal, penguins, and wallabies.
In 1925 they expanded their interests to the breeding of Arabian horses. The two women used their considerable fortune to build stables, purchase breeding stock, and establish a stud. Despite its relatively late start, Hanstead was soon considered "second only in importance to" Crabbet Arabian Stud, whose founders, husband and wife team Wilfrid Scawen Blunt and Lady Anne Blunt, had introduced the breed to England in 1878, and from whom the Yules bought and leased horses. A third stud, Courthouse, was also held up to be of the same level, and the three competed against each other at the annual show at the Roehampton Club
Gladys Yule died within a year of Judith Blunt-Lytton (Lady Wentworth), who had inherited Crabbet from her parents and run it for 40 years. The deaths of these two only children, at a time of high inheritance tax, meant that in 1957 a substantial number of British-bred Arabian horses left the country, improving the breed's bloodlines elsewhere. The Hanstead horses were appreciated in the United States and in South Africa.
Following the death of Gladys Yule in 1957, Hanstead Park was put on the market, where it remained uncared for over a considerable period of time. Many country houses were being demolished at this time.
In 1959 it was brought to the attention of the American evangelist Herbert W. Armstrong, who had arrived in England looking for a larger office for the British branch of his Radio Church of God. He bought the house and land as the site for his second Ambassador College campus. By the time of the purchase the guest house had already been sold separately to another buyer, who used the property as a private home like an island within the campus. Armstrong wrote in Chapter 72 of his autobiography that Trans World Airlines (TWA) had been considering Hanstead House as a school for stewardesses. "Yet this mansion, with these outstanding gardens, the aviary, greenhouses, cedars of Lebanon, all finally came to us for £8,000 ($22,800) - the not uncommon price of a five- or six-room cottage on a forty- or fifty-foot lot in America, - and that on terms that gave us several years to pay."
In 1959 Hanstead House was renamed Memorial Hall in memory of Richard David Armstrong, Herbert's deceased son. The college at Bricket Wood began its first freshman year in 1960. (The first Ambassador College opened in 1947 at Pasadena, California; in 1964 a third college opened in Big Sandy, Texas which for a brief time became Ambassador University. All three colleges have since closed down.) From the radio studio of Ambassador College, daily broadcasts of "The World Tomorrow" were heard around the world on hundreds of stations. There was also a sizeable printing establishment on the site. Improvements were made to the grounds: tennis courts, track, gymnasium, and an Olympic standard (imperial measurements) indoor swimming pool.
When Ambassador College closed its doors in 1974, the sports facilities were sold separately from the main buildings and eventually became part of a sports centre. The pool, one of the most modern in the area, became home to Verulam amateur swimming club in 1979.
The college became a corporate training centre, first for the Central Electricity Generating Board and then, from 1993, to the banking group HSBC. In 2004 a volunteer-led community woodland was established on land given by the bank; Hanstead Wood has won a Green Flag Award.
HSBC announced the closure of the centre in July 2011, moving its training to other group sites in India and Manila.
Hanstead Park has been acquired by St Congar Land, a property development company "with a general focus towards residential uses". They have submitted plans to St Albans District Council for 167 new dwellings, plus the conversion of Hanstead House itself. The estate agent's particulars pointed out that the house is not a listed building, nor is the land a conservation area, meaning that the developer would be somewhat freer of constraints than in many similar sites. One of the St Congar directors referred to the Hanstead Park as a brownfield site, i.e. previously developed land, although it sits within the Green Belt.
There are still commercial stables operating from Hanstead, though as a livery yard and riding school rather than as a stud.
= = = Robert Keeton = = =
Robert Ernest Keeton (December 16, 1919 – July 2, 2007) was an American lawyer, jurist, and legal scholar. As a law professor at Harvard Law School and a United States District Judge of the United States District Court for the District of Massachusetts he was known for his work on torts, insurance law, and practical courtroom tactics. Keeton, with Jeffrey O'Connell of the University of Virginia School of Law, played a key role in the advancement of no-fault automobile insurance.
Keeton was born in Clarksville, Texas. He was the second youngest of five children of William Keeton (who owned a general store) and Ernestine Teuton Keeton. One of his brothers, W. Page Keeton, also became a prominent lawyer and educator. Keeton earned his Bachelor of Business Administration from the University of Texas at Austin and his Bachelor of Laws from the University of Texas School of Law. As an undergraduate he became one of three students inducted into the Friar Society, an honor society at the University of Texas. In law school he was the assistant editor-in-chief of the "Texas Law Review". Keeton went into private practice with the law firm of Baker & Botts in Houston before joining the United States Navy in World War II. As a lieutenant serving aboard the escort aircraft carrier USS "Liscome Bay" (CVE-56) he survived the sinking of the ship on November 24, 1943, by a torpedo from the Japanese submarine I-175. Keeton, clinging to debris for hours, was later pulled from the ocean. He was awarded a Purple Heart. Keeton returned to Baker & Botts in 1945 after the war. He later taught at Southern Methodist University.
Keeton joined Harvard Law School in 1953, where he would remain until 1979. In 1954, he wrote "Trial Tactics and Methods", a book of practical advice on courtroom skills. Keeton later developed a program at Harvard (later used at other law schools) in which experienced trial lawyers taught students. One rule of Keeton's program was to not ask hostile witnesses open-ended questions. In 1956, Keeton received his Doctor of Juridical Science from Harvard. In 1973, he was named the Langdell Professor of Law. Keeton served as associate dean from 1975–1979. In the early 1970s, Keeton worked with University of Virginia School of Law professor Jeffrey O'Connell on a study that contributed to the development of no-fault automobile insurance, later adopted by many states. Under a no-fault system, damages below a certain level are paid by insurance companies, thus avoiding a determination of who was at fault.
Keeton was nominated by President Jimmy Carter on January 25, 1979, to the United States District Court for the District of Massachusetts, to a new seat authorized by 92 Stat. 1629. He was confirmed by the United States Senate on March 21, 1979, and received his commission on March 23, 1979. He assumed senior status on February 28, 2003. His service terminated on September 8, 2006, due to retirement. In 1979 Chief Justice Warren Burger appointed him chair of the Standing Committee on Rules of Practice and Procedure of the Judicial Conference of the United States, a body responsible for developing the Federal Rules of Civil Procedure and Federal Rules of Criminal Procedure.
Keeton presided over the 1988-1989 mail fraud and obstruction of justice trial of Lyndon LaRouche and eleven associates, which ended with Keeton declaring a mistrial. He also presided over the 1995 "Lotus Dev. Corp. v. Borland Int'l, Inc." trial involving the extent of software copyright, a case that later was decided by the Supreme Court. In 1984 Keeton, along with older brother Page as lead author, and professors Dan Dobbs and David Owen, published the 5th edition of "Prosser and Keeton on Torts". The book, based on William Prosser's influential "Prosser on Torts" (1941), became a foundational text of tort law and has become frequently used as a law textbook and reference work for many law students, lawyers, and jurists.
Keeton died of complications of a pulmonary embolism in Cambridge, Massachusetts, where he lived. He was 87.

The Banahaw Broadcasting Corporation (often shortened to BBC) was a Philippine television network that began operations on November 4, 1973 and ceased transmission on March 20, 1986.
DWWX-TV (formerly DZAQ-TV) station owned by ABS-CBN was shut down following the declaration of Martial Law in 1972, and served as the flagship station of BBC. Roberto Benedicto, a crony of then-President Ferdinand Marcos and owner of the Kanlaon Broadcasting System, took over the ABS-CBN Broadcasting Center complex on Bohol (now Sergeant Esguerra) Avenue in Quezon City after the KBS Studios along Roxas Boulevard in Pasay City (which were ironically sold to them by ABS-CBN in 1969) were destroyed by fire on June 6, 1973, a few months before BBC went on air. The new network was named the "Banahaw Broadcasting Corporation" after Mount Banahaw, a dormant volcano located in southern Luzon known for its hot springs and mystical associations.
