Patent GB-979254-A (GB)
Title: Improvements relating to control reservoir charging and release devices
Inventor: SIMMONS ARTHUR WILLIAM
IPC: B60T15/54
Filed: 1962-01-17
Abstract: 979,254. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. Dec. 21, 1962 [Jan. 17, 1962; Sept. 4, 1962], Nos. 1771/62 and 33808/62. Heading F2F. In a control reservoir charging and release device for a fluid pressure operable braking system a release valve is arranged such that it is also actuable as an initial control reservoir charging valve means, a valve portion of which is manually operable to connect the control reservoir to a source of lower pressure. As shown, the device has a diaphragm 2 subject on one side to control reservoir pressure in chamber 1 and to atmospheric pressure and the force of spring 3 on the other side. The diaphragm 2 acts on a stem 5 which in turn acts on a spring-loaded valve 9 held in sealing engagement with a seat 14. When the control reservoir is charged and the valve 9 is (as shown) held against the seat 14 by the control reservoir pressure in chamber 1 acting on the diaphragm 2 and it is required to release some excess pressure in the control reservoir or to completely release the pressure in the control reservoir, a lever 17 is operated to move the valve 9 off its seat by means of the stem 15. In the former case the control reservoir pressure equalizes with brake pipe pressure in chamber 21 through the restriction 12 and open valve 9. In the latter case, the brake pipe pressure being zero, the control reservoir pressure will be quickly reduced so that the valve 9 can be moved upwards and held by spring-loaded detents 8. The control reservoir pressure can then be completely released. To charge the control reservoir, the valve 9 being held by the detents 8, brake pipe pressure is communicated through the open valve 9 and restriction 12 to the control reservoir until the pressure of the latter acting in chamber 1 is sufficient to overcome the spring 3 so as to move the valve 9 on to its seat. Further charging of the control reservoir can then only take place through the normal sensitivity choke. In modifications the valve 9 is not subject to brake pipe pressure on both sides and so may be lifted by that pressure to charge the control reservoir and a further valve may be interposed between the valve 9 and the lever. 17 to enable excess control reservoir pressure to be released direct to atmosphere.

Title: Improvements in the production of brominated styrene polymers
IPC: C08F8/20
Filed: 1956-01-19
Abstract: Finely-divided polymers of styrene, its derivatives, e.g a -methyl, o- and p-methyl and p-ethyl styrenes and copolymers, e.g. with vinyl acetate, vinyl methyl and ethyl ethers, butadiene isoprene, acrylic and methacrylic esters such as butyl, and acrylonitrile, are brominated with bromine gas, vapour or mist alone or admixed with chlorine to give flameresistant products. Softening agents such as polybutadiene, acrylic, maleic and fumaric acid esters may be present if required and the polystyrene may be superficially swollen with, for example, styrene, benzene, higher alcohols and esters.  In a modification expanding agents, e.g. pentane, hexanes, petroleum ether and cyclohexane may be present.  The bromine may be carried by an inert gas such as air, nitrogen, or carbon dioxide.  The process may be continuous, e.g. in vertical columns with the polymer in a fluidized state and the excess bromine above 0.5 to 5 per cent by weight may be removed by heating in a current of air or vacuum or by treating with dilute or gaseous ammonia or by boiling with water. Specifications 695,826 and 715,100 are referred to.

Title: Evaporation Apparatus.
IPC: B01D1/28
Filed: 1968-01-12
Abstract: 1,171,072. Evaporators, vapour-compression type. AQUA-CHEM, Inc. 12 Jan., 1968 [30 Jan., 1967], No. 1989/68. Heading B1B. Liquid, e.g. salt water, is partly evaporated in chamber 31, the vapours are withdrawn from the chamber through pipe 49 by compressor 50, the compressed vapour is supplied through pipe 51 to the tube-bundle 55 wherein most of the vapour condenses and boils the salt water flowing over the outer surface of the tube-bundle, the residual vapour and non-condensable gases flow, together with the condensate, into a vent condenser 22, mounted in the manifold on the end of the tube-bundle, where the residual vapour is condensed by heat-exchange with salt water which passes through the tubes of condenser 22 before entering chamber 31. The manifold on the end of tube-bundle 55 is divided by a partition into an upper half and a lower half; the upper half is connected by pipe 51 to the compressor, and the lower half houses the vent-condenser. Non-condensable gases are discharged from the condenser through pipe 57. Hot distillate, i.e. fresh water, is withdrawn from condenser 22 through pipe 56. Compressor 50 is driven by a diesel engine 14. Within chamber 31 is a supplementary boiler 70 comprising an open tank in which fresh water, circulated from and to the cooling jacket of engine 14 by pipes 78 and 76 respectively, is partly evaporated by means of exhaust gases from the engine which flow via pipe 74 through tubes in the open tank. The exhaust gases are then discharged through outlet 75. Some of the hot distillate flows from pipe 56 to the tank of boiler 70 whenever float 68 falls below a predetermined setting. Salt water is drawn into the system through strainer 12, and passes through heat exchanger 13 where it is preheated by lubricating oil circulated from engine 14. The water is then pumped through pipe 19 through plate-type heat exchanger 21 wherein it is heated by blow-down from sump 32 and by hot distillate from pipe 56. The salt water next flows through the tubes of condenser 22, and then through pipe 25 to pipe 27 where it mixes with some of the brine from sump 32. The mixture is then sprayed, through nozzles in tube 29, over tube bundle 55 in chamber 31. The pressure in chamber 31 is maintained constant by diaphragm valve 44 which admits cool salt water from pipe 20 into the chamber whenever the pressure rises above a predetermined value. Cool distillate is withdrawn from the system through valve 64.

Abstract: 432,116. Ventilating vehicles. STONE & CO., Ltd., J., Deptford, Kent, and VIDAL, J. F. B., 48, Woodcrest Road, Purley, Surrey. Jan. 20, 1934, No. 2099. [Class 137] In a control device for a heating and ventilating system for railway and other vehicles, a motor 6 drives a fan and is controlled by an electromagnetic switch 5. This switch has its solenoid in the circuit of a reversible switch 1 which under summer conditions, is normally connected to the positive pole 2 of a dynamo driven by the vehicle so that when the dynamo is active the switch 5 is closed and the fan is driven by the vehicle battery connected across the terminals 7, 4. Under winter conditions, if the heater 8 is in use, a thermostatic device 9, 11 moves the switch 1 so that the coil 3 is connected across the battery irrespective of the activity of the dynamo, and the fan motor 6 is thereby energized to induce air over the heater 8 into the vehicle. At the same time the circuit of a thermostatic regulator 12 is connected to the battery so that a reversible motor 13 adjusts shutters controlling the passage of air through the fan. The thermostatic regulator employed may be that described in Specification 417,464, [Group XIII].

Abstract: 1,083,242. Laminates. FORMICA CORPORATION. Jan. 17, 1966 [Feb. 25, 1965], No. 2156/66. Heading B5N. A process for producing a decorative thermoset laminate comprises preparing an assembly in stacked relationship of one or more thermosetting resin-impregnated core sheets 6, and a thermosetting resin - impregnated decorative sheet 5 upon which is superimposed a release sheet 3, upon which in turn is superimposed a perforated stencil 2 having a thickness between 0À0005 inch and 0À030 inch, the release sheet 3 either being unperforated or if perforated having its perforations completely out of register with the perforations of the stencil 2, applying heat and pressure to consolidate the assembly into a unitary structure, and removing the release sheet and the perforated stencil from the consolidated structure. The result of the process is to form raised areas in the shapes of stars, geometrical designs, or messages, depending on the shape of the perforations, on the upper surface of the laminate, the raised areas being joined to the rest of the laminate upper surface via smooth curves. When the decorative sheet 5 is a solid colour it is in direct contact with the release sheet 3, but when the sheet 5 bears a printed design a transparent overlay sheet 4, as shown, is interposed. As described, the core sheets 6 are of thermosetting resin-impregnated Kraft paper, the decorative sheet 5 and the overlay sheet are impregnated with a colourless thermosetting resin, which in the case of the sheet 5 is pigmented if desired, the release sheet 3 is a non-adherable paper, e.g. parchment paper; paper coated, treated, or impregnated, with polyethylene, polypropylene or a polyfluorocarbon; paper treated with silicone oil, silicone resin, or an animoplast resin, e.g. urea or triazine resins; or paper coated with sodium alginate; or is a non-adherable metal, e.g. aluminium or copper, foil, or is aluminium foil glued to Kraft paper, and the stencil 2 is paper or metal foil. The treatment of the assembled stack is carried out in a laminating press between polished steel press-plates 1, 7.

Abstract: 1,031,351. Crimping and finishing yarns. CHEMSTRAND Ltd. March 29,1963 [Jan. 22,1962], No.2260/62. Heading D1F. [Also in Divison B5] A continuous filament yarn of a thermoplastic polymer is fed continuously between feed rollers downwardly in a vertical plane in a relaxed and tension-free condition, continuously passed through a dry heat zone so as to elevate the temperature of the yarn and impart a high degree of bulk there-, to, and the bulked yarn passed between delivery rollers in a relaxed condition and continuously collected while in such a relaxed condition. Yarns of acrylonitrile polymers and copolymers are specified. Tension may be applied to the yarn prior to its passage to the feed rollers. The dry heat zone may surround the yarn in the longitudinal direction so as to heat the yarn uniformly, the temperature to which the yarn is subjected in the dry heat zone preferably exceeding 80‹C. Yarn may be fed to the dry heat zone at a rate exceeding that at which it is withdrawn from the zone so as to relieve the yarn of tension. The bulked yarn may be collected by suction, or may be continuously formed into a package while in the relaxed condition. Apparatus as shown comprises a yarn supply package 2,tensioning device 3, guide 4 feed roller assembly 5, 6, heating tube 9, delivery roller assembly 7, 8 and suction apparatus 13. The feed and delivery roller assemblies are driven by motor 10 via belt drive 14 and variable speed gear units 11,12, so that the peripheral speed of the delivery rollers is less than that of the feed rollers. The bulked yarn may alternatively be taken up by a package building apparatus (not shown) disposed in a horizontal plane and so constructed that the yarn is still in a relaxed condition during its travel from the delivery rollers to the winding spindle of the package building apparatus, the speed of the winding spindle being controlled by, and coupled with, the speed of the delivery rollers.
