Title: Improvements in or relating to pressure regulating valves
IPC: B60T13/14
Filed: 1945-11-05
Abstract: 611,619. Fluid - actuated valves. BENDIX AVIATION CORPORATION. Nov. 5, 1946, No. 29408. Convention date, Nov. 25, 1944. [Class 135] A pressure regulating valve, in which a motor part can be connected to either a pressure port or an exhaust port, has separate inlet and exhaust valves, the former being movable from its seat by the latter and being connected to a piston, one side of which is subjected to the supply pressure and the other side to the pressure at the motor port. A self-lapping valve has an inlet port connecting an inlet chamber 50 to an accumulator, a motor port connecting a motor chamber 22 to, e.g., a fluid-pressure operated brake, and an exhaust port connecting an exhaust chamber 24 to a reservoir. A spring-loaded inlet valve 54, seating on a facing 56 in a hollow casing insert 58, has an extension 62 engaging an exhaust valve 16. A flange 66 on the exhaust valve is supported by a nut 70 threaded on to the lower end of the insert. The exhaust valve 16 seats on the upper edge of a central port 44 in a piston 20 which may be operated by a lever 26 acting through compression springs. A piston 82 rigidly attached to the inlet valve slides in a hollow cap member 88 and encloses a space 92 in restricted communication through passages 98, 102 with the motor chamber 22. The diameter of the piston 82 is slightly less than that of the inlet valve seat, so that a relatively small manual effort suffices to open the valve, and the pressure acting in the space 92 prevents the inlet valve remaining permanently open when high motor pressures are required. The throttling effect of the passages 98, 102, causes a time lag between the building- up of pressure in the motor chamber 22 and in the space 92, thus "ensuring a large, initial opening of the inlet valve. Specification 593,479 is referred to.

Filed: 1921-11-07
Abstract: 179,889. Wistoft, S. May 10, 1921, [Convention date]. No Patent granted (Sealing fee not paid). Indicating-mechanism. - Consists in dial arrangements for a weighing-scale of the kind wherein the weighing capacity of the scale may be doubled by the actuation of adjusting means which also automatically position a plate so as to obscure that series of indicating-numerals which are not requisite to the altered capacity of the scale. In the example shown in Fig. 1, the indicating-numerals are marked on a plate c the upper row of numerals corresponding to the lower weighing capacity and the other row to the higher weighing capacity. When adjustment is made to alter the weighing capacity, the plate c is automatically moved up or down to display the correct set of numerals through holes e in the casing. The holes e may be arranged below the graduations d or both above and below. In a further modification the plate c rocks upon an horizontal pivot in order to bring the requisite set of numerals into view, whilst in a further modification, Fig. 4, the plate c has a slot h through which numerals and graduations on a stationary dial g are viewed, the plate being moved automatically in a vertical direction to obscure those numerals not required. The dial arrangements may be modified to permit readings to be taken from both sides of the dial.

Title: Improvements in or relating to the production of petroleum coke
IPC: C10B55/00
Filed: 1959-09-01
Abstract: Petroleum coke suitable for conversion into graphite for use in nuclear reactors is made by coking an oil obtained by removing asphaltic constituents from a residual oil by extracting the oil with a liquefied normally gaseous hydrocarbon and distilling off the normally gaseous hydrocarbon.  Methane, ethane and preferably propane and butane may be used as the extracting hydrocarbon, the extraction being carried out under conditions of temperature and pressure such that the extracting hydrocarbon is in liquid form. The oil obtained by the extraction treatment may, prior to coking, be treated with an oxygen-containing gas, e.g. air, at between 150 DEG  and 400 DEG C., preferably 200 DEG  and 300 DEG C., and at atmospheric pressure or at elevated pressure, e.g. between 2 and 5 kg/cm2.  A proportion of 50 to 175 gms. of oxygen per kilogm of extracted oil is preferably used. The extracted oil may be coked by passing the oil through a pipe still heated to between 450 DEG  and 525 DEG C., preferably between 475 DEG  and 510 DEG C., the residence time being such that no coke deposits are formed in the still and the outlet pressure being between 7 and 35 atm. gauge, discharge being made into a heated coking chamber in which the coke is produced.  Alternatively, the extracted oil may be deposited on petroleum coke particles in a fluidized bed at between 450 DEG  and 650 DEG C. under such conditions that the contact time is between 5 and 60 seconds.  The coke thus produced is then preferably calcined at between 1100 DEG and 1400 DEG C. before being mixed with a binder, shaped and graphitized.  The raw shaped pieces are first heated to between 300 DEG  and 500 DEG C. to remove volatile matter and then finally at between 2500 DEG  and 3000 DEG C. for 2 to 5 days.
