A gate valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn’t be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry. For extremely thick fluids, a specialty valve often known as a knife valve is used to cut through the liquid. On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening. This means that flow rate does not change evenly with stem travel. Also, a partially open gate disk tends to vibrate from the fluid flow. Most of the flow change occurs near shutoff with a relatively high fluid velocity causing disk and seat wear and eventual leakage if used to regulate flow. Typical gate valves are designed to be fully opened or closed. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.
Gate valves are characterised as having either a rising or a nonrising stem. Rising stems provide a visual indication of valve position because the stem is attached to the gate such that the gate and stem rise and lower together as the valve is operated. Nonrising stem valves may have a pointer threaded onto the upper end of the stem to indicate valve position, since the gate travels up or down the stem on the threads without raising or lowering the stem. Nonrising stems are used underground or where vertical space is limited.

Julius Henry “Groucho” Marx (October 2, 1890 — August 19, 1977) was an American comedian and film and television star. He is known as a master of quick wit and widely considered one of the best comedians of the modern era. His rapid-fire, often impromptu delivery of innuendo-laden patter earned him many admirers and imitators. He made 13 feature films with his siblings the Marx Brothers, of whom he was the third-born. He also had a successful solo career, most notably as the host of the radio and television game show You Bet Your Life. His distinctive appearance, carried over from his days in vaudeville, included quirks such as an exaggerated stooped posture, glasses, cigar, and a thick greasepaint mustache and eyebrows. These exaggerated features resulted in the creation of one of the world’s most ubiquitous and recognizable novelty disguises, known as “Groucho glasses”, a one-piece mask consisting of horn-rimmed glasses, large plastic nose, bushy eyebrows and mustache.
Groucho Marx was, and is, the most recognizable and well-known of the Marx Brothers. Groucho-like characters and references have appeared in popular culture both during and after his life, some aimed at audiences who may never have seen a Marx Brothers movie. Groucho’s trademark eye glasses, nose, mustache, and cigar have become icons of comedy—glasses with fake noses and mustaches (referred to as “Groucho glasses”, “nose-glasses,” and other names) are sold by novelty and costume shops around the world.
Nat Perrin, close friend of Groucho Marx and writer of several Marx Brothers films, inspired John Astin’s portrayal of Gomez Addams on the 1960s TV series The Addams Family with similarly thick mustache, eyebrows, sardonic remarks, backward logic, and ever-present cigar (pulled from his breast pocket already lit).
Alan Alda often vamped in the manner of Groucho on M*A*S*H. In one episode, “Yankee Doodle Doctor”, Hawkeye and Trapper put on a Marx Brothers act at the 4077, with Hawkeye playing Groucho and Trapper playing Harpo. In three other episodes, a character appeared who was named Captain Calvin Spalding (played by Loudon Wainwright III). Groucho’s character in Animal Crackers was Captain Geoffrey T. Spaulding.
On many occasions, on the 1970s television sitcom All In The Family, Michael Stivic (Rob Reiner), would briefly imitate Groucho Marx and his mannerisms.
Two albums by British rock band Queen, A Night at the Opera (1975) and A Day at the Races (1976), are named after Marx Brothers films. In March 1977, Groucho invited Queen to visit him in his Los Angeles home; there they performed “’39″ a capella. A long-running ad campaign for Vlasic Pickles features an animated stork that imitates Groucho’s mannerisms and voice. On the famous Hollywood Sign in California, one of the “O”s is dedicated to Groucho. Alice Cooper contributed over $27,000 to remodel the sign, in memory of his friend.
In 1982, Gabe Kaplan portrayed Marx in the film Groucho, in a one-man stage production. He also imitated Marx occasionally on his previous TV sitcom Welcome Back, Kotter.
Actor Frank Ferrante has performed as Groucho Marx on stage for more than two decades. He continues to tour under rights granted by the Marx family in a one-man show entitled An Evening With Groucho in theaters throughout the United States and Canada with piano accompanist Jim Furmston. In the late 1980s Ferrante starred as Groucho in the off-Broadway and London show Groucho: A Life in Revue penned by Groucho’s son Arthur. Ferrante portrayed the comedian from age 15 to 85. The show was later filmed for PBS in 2001. Woody Allen’s 1996 musical Everyone Says I Love You, in addition to being named for one of Groucho’s signature songs, ends with a Groucho-themed New Year’s Eve party in Paris, which some of the stars, including Allen and Goldie Hawn, attend in full Groucho costume. The highlight of the scene is an ensemble song-and-dance performance of “Hooray for Captain Spaulding”—done entirely in French.
In the last of the Tintin comics, Tintin and the Picaros, a balloon shaped like the face of Groucho could be seen in the Annual Carnival.
In the Italian horror comic Dylan Dog, the protagonist’s sidekick is a Groucho impersonator whose character became his permanent personality.
The BBC remade the radio sitcom Flywheel, Shyster and Flywheel, with contemporary actors playing the parts of the original cast. The series was repeated on digital radio station BBC7. Scottish playwright Louise Oliver wrote a play named Waiting For Groucho about Chico and Harpo waiting for Groucho to turn up for the filming of their last project together. This was performed by Glasgow theatre company Rhymes with Purple Productions at the Edinburgh Fringe and in Glasgow and Hamilton in 2007-08. Groucho was played by Scottish actor Frodo McDaniel.
