Filed: 1944-09-13
Abstract: 588,926. Hydraulic systems ; ; steering ships &c. ARMANDIAS, L. S. (Soc. d'Inventions Aeronautiques et Mecaniques, S.I.A.M.). Sept. 13, 1944, No. 17509. [Classes 4 and 114] Rudders &c. are controlled by centring means fed by a continuously acting hydraulic pressure source and operating whenever the rudder is displaced from its-central position, together with hydraulically urged steering means also fed by a continuously acting source of hydraulic pressure and capable of applying a load in excess of the centring load for effecting the steering movements under control of a valve device, itself controlled by an operator. Pressure liquid from an hydro-pneumatic accumulator 25 flows through a reducing valve 23 to oppositely arranged cylinders 11, 16 containing free pistons 12, 17. against which abut the ends of a control rod 5, geared to the rudder 1. Displacement of the rudder can only take place against the pressure of the liquid on one or other of the pistons 12, 17. To effect steering movements, the liquid from the accumulator 25 acts directly through a manually-operated control valve 37 on one or other of two pistons 31, 32 in cylinders 33, 34, the pistons being connected to opposite ends of the tiller 26 and overcomes the restoring effect of the pistons 12, 17. Both circuits discharge into a common reservoir 79 from which a pump 75 returns the liquid to the accumulator 25, pressure being maintained in the centring circuit by a sustaining valve 73. In a modification, the centring cylinders are formed as extensions of the steering cylinders and rods projecting from the pistons of the latter engage the pistons of the former. Specification 509,923 is referred to.

Patent GB-997825-A (GB)
Title: Production of chlorinated hydrocarbons
Inventor: LEE DENIS
IPC: B01J27/06
Filed: 1962-05-08
Abstract: Chlorinated hydrocarbons are made by heating feed gases comprising ethylene or a chlorinated ethylene, hydrogen chloride, and molecular oxygen in a zone containing a supported catalyst of the Deacon type containing copper chloride wherein cuprous chloride vapour additional to that derived from the catalyst utilized in the reaction zone is introduced into the reaction zone at a position prior to the catalytic zone.  It is preferred to introduce the additional cuprous chloride vapour with the feed gases to the reactor.  The partial pressure of the cuprous chloride in the feed gases should approximate to the vapour pressure of the cuprous chloride prevailing in the first portion of the catalytic zone, and this additional cuprous chloride may be added to the feed gases by passing said feed gases over a heated bed containing cupric chloride or cuprous chloride on a support or a heated bed of cuprous or of cupric chloride or by passing the feed gases through a bath containing a molten mixture of cupric and potassium chlorides.  The oxychlorination may be carried out over a fixed catalyst bed which may be graded or over a fluidized bed.  The examples which also contain comparative data outside the scope of the invention in that the additional cuprous chloride is omitted, describe the following methods of saturating the gases stream with cuprous chloride: crystalline cuprous chloride diluted with glass particles, silica gel impregnated with cupric chloride, cupric chloride supported on alumina and diluted with glass particles, and also containing potassium chloride. Ethylene is converted over a catalyst of copper chloride potassium chloride on activated alumina to 1:2-dichloroethane, and with similar results over a silica gel supported catalyst and vinyl chloride together with hydrogen chloride and air are converted to 1:1:2-trichloroethane over a catalyst of copper and potassium chloride on alumina.
