Large hollow articles i.e. articles having at least two dimensions greater than 10 inches are rotationally cast in a process which involves: (a) Providing in a metal mould a liquid charge comprising epsilon caprolactam and an anionic catalyst and catalyst promoter for its polymerization, the charge being heated to 140-180‹ C. and kept under a dry inert atmosphere while in the mould, the charge being a mixture which when polymerized at 140-180‹ C. increases in viscosity from 10 to 100 centipoises in 1 to 3 minutes and from 1,000 to 10,000 centipoises in 1 to 6 minutes, from 100 to 400 centipoises in not more than 2 minutes at 150-180‹ C., the charge being sufficient to form a layer of average thickness between 10 and 100 mils. (b) Closing the mould and rotating it at a rate of between 1 and 20 r.p.m., until the liquid charge has been distributed over all the surface; this being accomplished while its viscosity is less than 10,000 centipoises. (c) Heating the mould at 150 to 175‹ C. after the completion of step (b) until the polymer has crystallized to at least 20% crystallinity, this step taking 3 to 30 minutes and its end being marked by contraction of the hollow object away from the walls. (d) Providing within the hollow article another liquid charge of the same composition of the first under a dry inert atmosphere, rotating the hollow article either alone or in the mould under the same conditions as in (b) to form a second layer in the hollow article and heating the mould as in (c) to crystallize this layer. The successive layers preferably have an average thickness of not more than 70 mils and the whole process lasts not more than 20 minutes. The mould may be rotated about two intersecting axes, the angular rotation rates about these axes being in the ratio between 2 and 5:1. The anionic catalyst may be a reaction product of lithium hydride and epsilon-caprolactam and the promoter a polyfunctional (trifunctional or higher) compound, preferably a trifunctional triazine.

Abstract: 567,977. Refining iron and steel. FORD MOTOR CO., Ltd., and RENSHAW, E. S. Aug. 27, 1943, No. 14044. [Class 72] In a process for refining ferrous metals such as pig iron, cast iron and steel by reducing the phosphorus content or removing it, the metal is melted in contact with solid fuel, such as coke in a cupola furnace lined with dolomite, stabilised dolomite, magnesite or other similar basic or neutral refractory, limestone or raw dolomite being added in sufficient proportion to satisfy the silica present and to allow an excess of base in the slag for the removal of the phosphorus. The melting may be carried out under controlled oxidising conditions such that the phosphorus is converted into phosphate and the excess of base in the slag is sufficient to prevent a reversion of the phosphate to phosphide which would be re-absorbed by the metal.

Filed: 1917-10-05
Abstract: 121,615. Brettell, W. G., and Adamson, A. J. Oct. 5, 1917. Circulating brine through chambers.-In systems for circulating freezing, chilling, or thawing brine through a number of separate circuits or refrigerating chambers, more especially on ships, a number of circulating pumps are connected through short branches fitted with regulating valves with three common return headers or mains and three common delivery headers or mains, these being connected with distributing headers arranged one above another in a vertical plane and fitted with a set of distributing cocks for the various circuits, as described in Specification 118,649. The brine returning from the chambers or circuits is delivered by a set of cocks to one of three compartments of a return tank, as described in Specification 119,670, the compartments being connected with the pump return mains. The pumps 2, Fig. 1, may be arranged in an insulated compartment 3 outside a room 1 containing the return and distributing headers 5, the return tanks 6, and evaporators 7. the tanks and headers being arranged in parallel planes. The arrangement of one pump 2 and a set of headers is shown in Fig. 10, and an end view of the headers and connexions is shown in Fig. 5. The distributing headers are in two sets. the lower set being double. The brine from the freezing section of the return tank passes through a pipe 45 to the rear compartment 8<x> of the lowest header, and thence through the short connexion 11 and valve 17 to the pump 2, from which it is delivered through a second valve 17 to a pipe 14 and the rear compartment 8<x> of the top header. The brine flows from this last compartment to the evaporator and back to the front compartment 8 of the lowest header, and also, by an end bend, to the upper front compartment 8. The middle headers 9, 9<x> of each set are for thawing brine, which may be sent through a heater, and the adjacent headers 10, 10<x> are for chilling brine. The distributing cocks 30 are fitted to each set of headers, and each cock may supply brine to one or more circuits 34. The freezing brine may be sent through a by-pass from the top compartment 8<x> to the bottom compartment 8, instead of through the evaporator. The pump valves 17 are constructed as shown in Fig. 11, the branches 18, 19, 20 corresponding with the return or delivery pipe connexions 11, 12, 13 or 14, 15, 16, Fig. 10, and the salves are set according to the temperature of the brine to be circulated. In a modification, a set of three valves is employed in place of each multiple way pump valve. Another arrangement of the whole plant is described in which the short branches 11, 12, 13, 14, 15, 16 from the pumps are connected with the return tanks and the distributing headers by mains, instead f through rear compartments of the distributing headers, the evaporators being placed opposite to the pumps at one end of the room and the return tanks and headers opposite one another at the other end. Specification 28113/10 is referred to.

Title: Electrically controlled Fluid Braking System for Rapid Transit Cars
IPC: B60T13/66
Filed: 1968-03-26
Abstract: 1,187,212. Electro-pneumatic brake control systems. WESTINGHOUSE AIR BRAKE CO. 26 March, 1968 [28 July, 1967], No. 14499/68. Heading F2F. An electro-pneumatic train brake system has a continuously variable electric control signal compared with a brake-pressure feedback signal to provide progressive braking. It provides inter alia, alternative use of a non- variable control signal; compensation for load and fading; of dynamic brake, and rapid movement of shoes from off to just touching position (i.e. inshot control). Electric control.-As shown, Fig. 1, a current inversely proportional to the desired degree of braking is circulated through a P wire to a magnetic amplifier to control the supply from transformer 58 to charge capacitor 31; series resistor 66 smooths any "notches" " in the control current. At maximum current corresponding to " full release " brake transfer relay 24 is energized to charge capacitor 31 to a preset value from supply 27 to ensure the brakes are fully off. In alternative mode with switch 10 in " A & R " position, signals on A or R train lines control relays AR and RR to charge or discharge capacitor 31 through resistors 43 or 33 to the required degree which is maintained when the command signal is removed. (Energization of relay AR corresponds to absence of a command). The signal on capacitor 31 is amplified at 51 and a car-load signal added by amplifier 75 (from load transducers 80, 81) and a further signal corresponding to the effectiveness of the dynamic brake is added by amplifier 98. This air-brake-control signal is fed to X and Y resistance panels (for the two ends of the car), where it is opposed by bias from brake-pressuretransducers 121, 127 to provide control signals at terminals 115, 130, which are amplified at 132, 133, and fed to " A & R " circuits 136, 137 to selectively energize the Application and Release Magnets, according to the polarity of the signals. The output of the resistance networks is reduced to zero at terminals 115, 130 at the desired pressure by transducers 121, 127. Inshot Control circuit 180, Fig. 2, rapidly brings the shoes into contact with the braking surface at the initiation of a brake application when the control signal is slightly reduced relative to the bias 185. Plumbing.-Fig. 3 illustrates the control valving apparatus provided at each end of the car, including the electrically-controlled application and release magnet valves 254, 255, the emergency valve 261 connected to the quickaction-pressure chamber 271; pressure balancing relay-valve 264, and dump valve 256 energized from a wheel slip control (not shown).
