Title: Improved height control system for vehicle fluid suspension
IPC: B60G17/052
Filed: 1958-04-30
Abstract: 830,326. Maintaining vehicle height constant. GENERAL MOTORS CORPORATION. April 30, 1958 [May 16, 1957], No. 13727/58. Class 108(2) A manual overide control is provided to enable a vehicle to be raised above the height at which it is normally automatically maintained by the action of levelling valves 20a, 20b and 20c controlling the supply of air from a compressor 68 and reservoir 67 to respective pneumatic bellows type springs 14a, 14b and 14c. Air supplied by the normal action, or by the overide, is limited to a pre-determined pressure by a valve 92 carried by head 96 acted on by a diaphragm 97 subjected to opposed springs 95, 99. The pressure thus limited, may pass by a conduit 76 to the normal pressure air connections of the valves 20a, 20b, 20c, and may pass to a passage 15. The latter may be closed (as shown) by an element 121 of a manually operated valve 120 in its normal setting. Exhaust air from the valves 20 can then pass via conduits 77, 77a, passage 122, spring loaded valve 108 and conduit 82 to a low pressure reservoir 83. When the vehicle is to be lifted above its normal position, the valve 120 is displaced leftwards by a pin 130 carried by a cable operated lever (Figs. 5 and 6, not shown) to open passage 115 and close passage 122. Air from passage 115 can then pass along peripheral flats of the valve 120 (Fig. 131, not shown) and thence to conduits 77, 77a. The air can then pass to the springs 14 via the respective exhaust valves of the valves 20 (each exhaust valve permits flow in the reversed direction). As the vehicle is raised above normal height the exhaust valves are drawn to open position. The spring-loaded valve 108 prevents a sudden release of air through the open exhaust valve when the manual override is moved back to closed position.

Title: Improvements in or relating to the production of cellular synthetic resin compositions
IPC: C08J9/12
Filed: 1944-07-20
Abstract: Cellular synthetic resin products are made by forming a composition comprising a liquid hardenable resin, an inert volatilizable liquid, a hardening agent and a surface-active agent, foaming the composition by vaporizing the inert liquid while the resin is still liquid, and maintaining the foamed composition at hardening temperature until the resin has hardened.  In a preferred form, an aqueous syrup of a hardening agent and a surface-active agent, and the mixture is poured into a preheated heat-insulated mould, the heat of reaction being sufficient for hardening and vaporizing.  Resins derived from formaldehyde and phenol, metacresols unsubstituted in o- and p-positions, or resorcinol may be employed; hardening agents specified are hydrochloric acid for phenol- and urea-formaldehyde resins, and alkali hydroxides for resorcinol-formaldehyde resins. Surface-active agents specified are sulphonated castor oils, animal glue, cationic soaps, and cetyl pyridinium bromide.  Bubble formation may be assisted by incorporating a finely-divided inert solid, e.g. powdered barytes or silica (diatomaceous earth), or powder prepared from silica gels.  In examples, an aqueous phenolformaldehyde resin syrup is mixed with sulphonated castor oil and hydrochloric acid, with and without silica, and the mix is placed in a rubber-lined wooden mould which has been preheated to 50 DEG  C.

Title: Improvements in or relating to rotary tobacco cutting machines
IPC: A24B7/10
Filed: 1945-06-04
Abstract: 594,613. Sharpening cutters. DEARSLEY, G.. and MOLINS MACHINE CO., Ltd. June 4, 1945, No. 14010. [Class 60] In a tobacco-cutting machine, in which blades 2 on a rotary head 1 are swept across a mouth 3 and are sharpened by a grinder 5 rotating on a stationary axis, the grinding- wheel is dressed by a diamond 7 mounted in a bracket 6 on the head 1. The grinding-wheel 5 is fed forward continuously to compensate for wear and dressing, a feed rate of .00007 inches per minute being referred to. The grinder 5 is preferably driven independently of the head 1 so that synchronism between the dresser and the grinder, resulting in repeated attack by the dresser on the same parts of the grinder, with consequent grooving, is definitely avoided. If the grinder and the cutter head have a common drive, the speed relationship must be chosen to avoid such grooving. Speeds of 1440 and 150 r.p.m. for the grinder and head respectively are mentioned. In operation, the diamond is swept across the face of the grinder and scores out a very shallow groove 8, the multiplicity of such grooves cut at random effectively dressing the grinder. As the wheel 5 is tilted to the plane of the knives, the dresser operates at the lower part of the wheel. Specifications 365,997 and 588,129, [Group I], are referred to.

As shown in Fig. 3, a is the negative and associated multi-colour screen b is the additional multi-coloured screen, c is the positive emulsion, and d is the multi-colour screen between the emulsion and the paper support. As shown in Fig. 5, the contact-printing frame is provided with register pins f and holding screws g. The enlarging apparatus and the taking apparatus also have register pins. Films, papers and screens have corresponding holes. Plates are provided with pins, and those in the apparatus are dispensed with. One corner of plates, films, papers, and screens is cut off for orientation purposes. A multi-colour screen with a regular pattern is produced'by placing carbon paper on white paper, and running a pin-wheel thereover a number of times, producing a reduced photographic copy of the dot screen, and using this copy to produce four negatives, the copy being shifted for each negative. Photo-mechanical printing plates are produced from these negatives, and used for printing the four colours of the multi-colour screen. A celluloid foil is consecutively printed in black with the four printing plates, and a fifth photo-mechanical printing plate produced from this foil is used to print over the multi-colour screen in grey to cover the colourless spaces. A multicolour screen with an irregular pattern may be produced in a similar manner using celluloid foils sprayed with black oil colour. The multicolour screens may be on glass, oiled paper, celluloid, or mica foil.

Title: Improvements relating to electrical batteries
Inventor: BACON FRANCIS THOMAS
IPC: H01M8/04
Filed: 1957-05-03
Abstract: 822,086. Fuel batteries. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 25, 1958 [May 3, 1957], No. 14220/57. Class 53. An hydrogen-oxygen fuel cell having porous electrodes in which the difference in pressure between the gases and the electrolyte is balanced by capillary attraction in the pores of the electrodes, is provided with a hydrogen circulation system including a condenser for the steam carried by the hydrogen, the condensed water being periodically released by a valve controlled by the difference in pressure between the electrolyte and the hydrogen. Fig. 1 shows a battery of fuel cells which may be of the kind described in Specification 667,298. The battery is divided by a distributer plate 2 containing openings for the ingress of the gases and electrolyte and removal of waste products. Hydrogen is supplied to the battery through a pipe 3 and is circulated by a pump 6 through a return pipe 5. Hydrogen leaving the battery emerges through a pipe 25 into a condenser 26 from which it leaves by a pipe 27 leading to the pump 6. The battery works at a temperature of about 200‹ C. and the circulating hydrogen carries steam which condenses in the condenser 26. When the condensate reaches the pipes 25, 27 it closes them and the circulation of hydrogen ceases. Oxygen is supplied through a pipe 10, and electrolyte is supplied through pipes 12, 15 and circulated through a pipe 14. The circuit for the electrolyte also includes a pipe 18 leading to the upper side of a diaphragm 30 in a control valve 19. The lower side of the diaphragm is subjected to the pressure of the hydrogen which is conveyed through the pipe 31. The difference in the pressures on the two sides of the diaphragm is balanced by an adjustable spring 32. A valve 41 is connected to the diaphragm and opens to allow water to flow from the condenser 26 to the atmosphere through a steam trap 45 when the pressure in the pipe 31 is reduced owing to the closing of the pipes 25, 27 by condensed steam. If steam is condensed at a greater rate than the formation of water in the battery, some of the condensate is released by the valve 19, the remainder being circulated round the exterior of the battery to act as cooling water and being returned as steam to the oxygen electrodes through pipes, (not shown). A circulating system may also be provided for the oxygen.
