Title: Moulding compositions
Inventor: BAXTER SAMUEL
IPC: B29C45/00
Filed: 1959-07-30
Abstract: The tendency of an article, produced by injection or extrusion moulding a thermoplastic synthetic resin, to contain sink marks or voids is substantially removed by the action of a blowing agent during moulding, the weight of the agent being less than 1% of that of the resin. In one example 6.8 grams of azodicarbonamide are mixed with 50 pounds of polystyrene pellets in a rotating drum and the mixture injected from apparatus at 218 DEG C. into shoe-heel moulds at 20 DEG C.  The nitrogen released prevents sink marks or voids in the heels.  The density of the finished heel is about 10% less than that of one formed from resin alone.  The blowing agent may alternatively be a bicarbonate.  Polyvinyl chloride, polythene or a copolymer of styrene with butadiene or acrylonitrile may also be moulded according to the invention.  Specification 916,802 is referred to.

Abstract: <PICT:0757171/III/1> Steam continuously circulated in a closed path to carry heat from a heat source to a reaction vessel is continously maintained at supercritical pressure throughout its circulation.  In the form shown, steam heated in a superheater 7 flows to heating tubes 30 in an endothermic reaction vessel 3b and then flows to a header 21, from which pumps 3, 5 return it to the superheater.  The reaction carried out in vessel 35 may be cracking and reforming naphtha in the presence of hydrogen and a catalyst, such as molybdenum oxide, at a pressure of 150 to 300 p.s.i. and at a temperature of 950 DEG  to 1050 DEG F.  At the start, low pressure steam is supplied through pipe 42 and is circuated by the pumps, a by-pass for the heating tubes 30 being open.  Small amounts of water from a tank 15 are then fed by a pump 17 into the header 21 and there flash into steam, until the required pressure and temperature are reached.  The added water is deaerated by repeated circulation through a deaerator 14, pump 17 and pipe 18. Combustion gases leaving the superheater 7 heat a hydrogen heater 8 and a steam generator 9.

Title: Improvements relating to vigilance control apparatus for automotive railway vehicles
IPC: B60T17/20
Filed: 1957-08-23
Abstract: 856,051. Automatic brake application. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., SIMMONS, A. W., and ROBERTS, L. J. Aug. 22, 1958 [Aug. 23, 1957], No. 26687/57. Class 103 (1). In a vigilance control apparatus for automotive railway vehicles, a timing reservoir is alternatively charged and discharged and should the pressure be allowed to fall below a predetermined value it causes a valve to vent, at a controlled. rate, a secondary independent reservoir to initiate a timed sequence of emergency apparatus which proceeds under the control of the reduction of pressure in the secondary reservoir and commences with a warning followed after a definite period of time, with automatic application of the brakes. When the timing reservoir 11 is fully charged the pressure opens a switch 15 to de-energize an electrically-controlled valve 14 to close choke 12 to the main reservoir and open choke 13 to atmosphere, the pressure in reservoir 11 decreases and at a certain pressure a piston 22 of a valve 18 is raised by spring 23 to allow fluid to flow from a delay reservoir 16 to a valve 19 to raise piston 24 to operate audible warning means 27, fluid then flowing to atmosphere via choke 20 and cock 21. If this warning is not acknowledged by a cancelling action to energize valve 14 to open choke 12 as described in Specification 856,052, the delay reservoir pressure falls until after a predetermined time, the pressure from reservoir 16 switches a valve 29 to vent the brake pipe 30 to atmosphere via pipe 32 to cause emergency brake application; shortly after, the pressure in reservoir 16 reaches a value at which valve 19 closes to switch off the warning means. To recharge the apparatus or to cancel the emergency apparatus, the valve 14 is energized to charge reservoir 11 from a main reservoir; simultaneously pressure build-up in the brake pipe charges reservoir 16 through a permanently open restricted passage in valve 29. The pressure build-up in the reservoirs being substantially at equal rates and is such that valve 18 is closed before the pressure in reservoir 16 reaches a value to open valve 19. The cock 21, situated out of reach of the driver when the vehicle is moving, is interlocked with means, e.g. switch 28, controlling a supply necessary for the vehicle drive; on closing of cock 21 to prevent venting of reservoir 21 and operation of the automatic apparatus, the supply is cut off; the cock may be situated in pipe 31 to prevent or permit charging of reservoir 16. Specification 856,053 also is referred to.
