Patent GB-173300-A (GB)
Title: Improvements in the manufacture and production of hydrochloric acid
IPC: C01B7/01
Filed: 1920-09-23
Abstract: In the manufacture of hydrochloric acid by direct combustion of hydrogen and chlorine, an igniting safety flame, preferably produced by burning a mixture of hydrogen and chlorine, is provided at the junction of the streams of the entering gases, which are so arranged as to cause the combustion to take place in a downward direction. The main gas supply is controlled in order to give equimoecular proportions of hydrogen and chlorine.  A shaft furnace having means for cooling the walls may be employed for the process and the gases are introduced at the top through two sets of pipes, the one pair surrounding the other.  The larger and outer pair supply the main flame and the inner pair supply the small safety jet with hydrogen and chlorine.  To effect complete combustion, the reaction gases are passed preferably after partial cooling over or through contact material placed at the lower end of the furnace and consisting of brick, chamotte, pumice, quartz lumps, &c. with or without metals or metal salts acting as chlorine carriers.  The resulting hydrochloric acid is withdrawn at the bottom and passed to absorption vessels. Specification 159,869 is referred to.

Patent GB-870458-A (GB)
Title: Detergent compositions
Inventor: SHEPHERD ERIC LOUIS
IPC: C11D1/72
Filed: 1958-08-25
Abstract: A detergent composition comprises (a) 60-90%, preferably 67-85%, of an organic sulphonate or sulphate detergent or a mixture thereof, (b) 5-30%, preferably 10-23%, of one or more alkylene oxide-phenol condensates and (c) 5-30%, preferably 10-23%, of one or more alkylene oxide-alcohol condensates, all percentages being by weight of total active detergent.  Component (a) may be any of the common sulphonate or sulphate detergents in the form of the sodium, potassium, ammonium or substituted ammonium, e.g. alkanolamine, salt, but is preferably a mixture of sodium alkylbenzene sulphonates having 8-13 carbon atoms in the alkyl group.  Any alkylene oxide may be present in (b) and (c), but it is preferred to use ethylene or 1:2-propylene oxide; any of the butylene oxides may, however, also be used.  The proportions of alkylene oxide are generally 4-40, but normally 6-25, moles of oxide per mole of phenol or alcohol.  The phenol in (b) may be phenol itself, a cresol, resorcinol or a dialkyl phenol, but is most desirably an alkyl phenol having 4-10 carbon atoms in the alkyl group, particularly octylphenol.  The alcohol in (c) is suitably a monohydric primary, secondary or tertiary alcohol of 6-20 carbon atoms; aliphatic alcohols are preferred, but such alcohols as the alkylbenzyl alcohols may also be used. Particularly suitable, however, are the condensates of ethylene oxide with oleyl and cetyl alcohols.  Component (b) or (c), or both, may also be mixed condensates obtained either by randomly condensing the phenol or alcohol with a mixture of ethylene and 1:2-propylene oxides, or a block copolymer obtained by condensing a phenol or alcohol containing up to 20 carbon atoms alternately with ethylene and 1:2-propylene oxides, the weight ratio of the former to the latter being 10:90 to 90:10, so that any block of polymerized ethylene oxide, together with either adjacent block of polymerized 1:2-propylene oxide, comprises less than about 10% of the average molecular weight of the compound. The composition usually contains 5-30% by weight of urea, which reduces the cloud point.  Alkali metal phosphates and polyphosphates, sodium silicate and sodium carboxymethyl cellulose may also be incorporated, and the compositions are generally produced as aqueous solutions containing 20-60% by weight of the composition. Specifications 645,129, 870,457 and U.S.A. Specifications 2,152,297, 2,263,312, 2,276,090, 2,340,654, 2,467,130, 2,467,131 and 2,467,132 are referred to.

Title: Improvements in gun systems including at least one gun to be mounted on a support with respect to which it can recoil as a whole against the action of resilient means
IPC: F41A25/02
Filed: 1955-09-27
Abstract: 778,156. Automatic guns. BREVETS AERO-MECANIQUES SOC. ANON. Sept. 27, 1955, [Oct. 16, 1954], No. 27520/55. Class 92.  Relates to an automatic gun which is movable as a whole for recoil with respect to a support, e.g., an aircraft wing, against the action of a spring and in which this recoil controls a part of the operation of the feed device for the gun. According to the invention powder gases supplied from a tap in the barrel are fed to a device which urges the gun in the recoil direction every time a shot is fired. This arrangement provides the requisite energy for operation of the feed device and permits the provision of a strong spring for urging the gun forwardly after recoil, which spring returns the gun quickly to the firing position and overcomes the shock of the breech block against its return spring at the end of its rearward stroke which shock tends to cause rearward movement of the gun. The gun is supported at the front by an aircraft wing element 6, Fig. 1, through a ball and socket device 7 in which the gun can slide and recoil against the action of a spring 8. At the rear, the gun is supported by an arm 9 hinged at its ends to the gun and to the wing framework. A feed mechanism 10 does not recoil with the gun which slides relatively thereto and is connected by a link 11 to the element 6. At every recoil a finger 12 carried by the gun lifts a roller 13 which serves to wind up a spring operating the feed mechanism. The gun barrel carries a piston 14 movable in a cylinder 15 provided in the ball element 7 and a gas tap 16 in the gun barrel feeds gases into the cylinder 15 to urge the whole of the gun rearwardly with respect to the elements 6, 7 every time a shot is fired, this action being added to the recoil proper. Shock-absorbers 19 may be interposed between a ring 17 on the gun barrel and a ring 18 rigid with the ball 7 and arranged so that the recoil stroke is not braked but at least the end of the forward return movement of the gun is slowed down. Each may consist of an oil filled cylinder 19, Fig. 3 in which moves a piston 20 provided with check valves 21 producing braking action during forward movement of the gun.

[Class 44.] In the lock according to the parent Specification, the projection which extends radially from the rotatable tumbler mechanism 9 and engages directly with the lower ends 7 of the bottom pair of lazy tong links 5 is replaced by a pair of pins 8 bent at 10 so that when the tumbler 9 is turned in either direction by a key one of the pins engages the periphery of a roller 3 which is thus pressed against one of the links 5 to contract the lazytongs 11 and retract the bolt 12 against the action of the springs 19. The roller 3 is rotatably mounted on a pin 6 carried by the lower ends of a pair of arms 4 which are adapted to swing about the pivotal axis 2 of'the links 5. To enable the bolt to be withdrawn from the inside of the door without the use of a key, the cover-plate 20 encloses a pivoted finger 21, Fig. 4, formed with a laterally projecting U-shaped end 24 which engages over a pin projecting from the bolt 12.
