Title: Spring-loaded valves
IPC: F16K17/04
Filed: 1974-07-10
Abstract: 1474373 Valves; fluid pressure brakes BENDIX WESTINGHOUSE Ltd 10 July 1974 [31 July 1973] 36319/73 Headings F2V and F2F A valve 19, 20 to control fluid flow from a compressor 18 to reservoirs 22, 23 in a fluid pressure braking system comprises an inlet port 7 and an outlet port 8 and a valve member 9 controlling flow between them. The stem of the valve member 9 slides in a bore in a piston 3 and the piston is biased by an adjustable loading spring 4. A light biasing spring 10 is interposed between the piston and the valve member. A breather port 11 is protected by a strainer 12. When the inlet pressure from the compressor 18 exceeds the pressure set by the spring 4 the valve opens and pressure builds up in the reservoir. With increasing pressure from the reservoir in the outlet port the piston 3 rises and at a predetermined pressure the loading effect of the spring 4 on the valve member is removed and the valve then acts as a check valve lightly biased by the spring 10. In the event of a failure in or downstream of the reservoir the piston falls and the valve will close if the inlet pressure falls below that set by the spring 4. In a vehicle braking system using the valves 19, 20 according to the invention, the two reservoirs 22, 23 are connected to a dual foot valve 15 controlling front brake actuators 24, 25 and rear brake actuators 26, 27. In the event of a failure occurring in the reservoir 22 (or 23) or the connections thereto valve 19 (or 20) allows the compressor to maintain the other reservoir 23 (or 22) at a pressure set by the spring 4 in the valve 19 (or 20). A line 29 fed via a service line control valve 28 provides a connection for a trailer. A protective valve 13 provides a feed to an emergency line 30 and, via a check valve 31, a feed to a parking brake control valve 32 the outlet from which passes to spring-brake release cylinders via a differential protection valve 33.

Patent GB-969993-A (GB)
Title: Process for the purification of lactams
Inventor: WEISER DIETER
Filed: 1962-09-26
Abstract: Lactams containing 4-12 carbon atoms are purified by treatment with activated hydrogen in the presence of acids at a pH of 3 to 0.5, the lactam being in the liquid phase, preferably dissolved in water or in an inert solvent.  The acids may be mineral or organic acids having a pH of 4.9 or less, e.g., sulphuric, hydrochloric, formic or acetic, and are used in amounts of 0.01-10.0%, preferably 0.1-10.0%, by weight of lactam.  The activated hydrogen may be in the form of nascent hydrogen or catalytically activated hydrogen.  In the former instance, nascent hydrogen is generated in the reaction mixture by a process which takes place in an acid medium but under conditions which leave the lactams unattacked, e.g. sodium borohydride and zinc dust and acids, preferably in the presence of an hydrogenation catalyst. Sufficient reagent to provide 0.001-0.5, particularly 0.001-0.2, moles of hydrogen per mole of lactam is employed. The treatment may be carried out in 20-80% by weight solutions in the temperature range -15-250 DEG C., preferably 50-100 DEG C. and at pressures ranging from normal to 10 atmospheres for times of up to 5 hours.  When catalytically activated hydrogen is employed the catalyst, generally 0.1-5% by weight of lactam, may be, e.g. palladium, platinum, nickel or noble metal oxides and may be supported on a carrier.  Pressures of 1-300 atmospheres may be used at temperatures in the range -15-250 DEG C., particularly 0-120 DEG C., and treatment continued until hydrogen uptake ceases or falls off. Where necessary the lactam is isolated by neutralization and/or filtration and distillation or sublimation. Lactams purified by the present process give polymers of improved colour rating, permanganate number and volatile base number (see Division C3).  Examples (1)-(12) describe the treatment of caprolactam with catalytically activated hydrogen and nascent hydrogen.  In Example (B) pyrrolidone is treated with catalytically activated hydrogen.  Specification 904,302 is referred to.ALSO:Polyamides are made from lactams containing 4-12 carbon atoms which have been purified by treatment in the liquid-phase, preferably dissolved in water or in an inert solvent, and in an acid medium at pH 3-0.5 with activated hydrogen.  The hydrogen can be in the nascent state or catalytically activated using the usual hydrogenation catalysts.  In examples caprolactam and pyrrolidene are purified and polymerized by heating with 3% hexamethylene-diammonium adipate under an atmosphere of N2 for 6 hours at 260-270 DEG C.  The polymers have colour ratings on the Hagen scale of 40-80. Specification 904,302 is referred to.
