Title: Improvements in or relating to electric discharge device circuit arrangements
IPC: H04L25/24
Filed: 1939-02-13
Abstract: 524,964. Valve relays. THIEMANN, W. H. A. (Bendix Aviation Corporation). Feb. 13, 1939, No. 4709. [Class 40 (v)] In a relay circuit energy is supplied from a local source to a load under the control of a single tube which is directly coupled to the relay tube and controls the bias thereof and so the conductivity signals received on the grid 3 of discharge device 20 control the discharge device 21 which allows pulsating current from the source 23 to pass to the secondary 19 of transformer 18/19. Under normal conditions valve 20 and the gas discharge tube 12 are passing current and valve 21 is blocked. When a signal is received grid 3 goes negative and decreases the current in valve 20 so that the potential drop between grid 5 and cathode 4 increases and the voltage across the tube 12 falls below the discharge valve. When the tube 12 stops discharging, the valve 20 becomes blocked and the potential drop across resistance 7, which supplies the bias for valve 21, is removed to allow valve 21 to become conductive.

Title: Improvements in braking mechanisms
IPC: B66D5/26
Filed: 1946-02-15
Abstract: 627,559. Fluid-pressure controlled brakes. GENERAL ELECTRIC CO., Ltd., and FOSTER, R. T., [Representative of FOSTER, H. H.]. Feb. 15, 1946, No. 4852. [Class 103 (i)] In a brake control system in which the brake is normally applied by fluid pressure acting on a first piston at one end of a slidable member connected to the brake, when the fluid pressure acting on a second piston at the other end of the member is reduced, the chamber of the first piston is directly connected to the pressure source and contains a third piston which carries a weight and is normally supported by the pressure fluid but which engages the slidable member to apply the brake if the fluid pressure fails. As shown, cylinders 8, 9 of pistons 6, 7 at the ends of a member 5 connected to a brake operating lever 2 are connected respectively to an oil pump 15 and to a control valve 21 which is also connected by pipe 19 to the pump. A pneumatic accumulator 27 provides a reserve of liquid under pressure. A piston 11 slidable in the cylinder 9 carries a weight 12 and is normally displaced from the piston 7 as shown by the fluid pressure a valve 16 being opened by the piston to byepass the pump when it reaches a predetermined height. A pressure relief valve of usual kind may replace the valve 16. The valve 21 is controlled by a manually operated floating lever 24 which is connected to the member 5 to give a follow-up action. Assuming the pistons to be in the raised position, downward movement of the lever 24 connects the cylinder 8 to the sump 17 through pipe 25 and a throttle valve 26, so that the member 5 descends under the pressure in cylinder 9 to apply the brake. When the lever 24 is raised the cylinder 8 is connected to the supply pipe 14 by the valve to release the brake. Should the oil pressure fail when the brake is off, the piston 11 moves downwards to abut on the member 5 so that upon subsequent operation of the valve 21 to vent the cylinder 8 the brake is applied by the weight 12. A hand or other pump may be arranged between the sump 17 and the lower end of the member 5 to enable the brake to be released when the main supply has failed. The pistons 6, 7 may be of equal areas, a reducing valve being arranged in the connection to the upper cylinder. The brake may be used for winding engines.

Title: Improved manufacture of aluminium nitride
IPC: C01B21/072
Filed: 1920-02-18
Abstract: Aluminium nitride is obtained by passing nitrogen into pure molten alumina in presence of a reducing agent such as carbon or a reducing gas or vapour while electric energy is supplied to maintain the temperature.  Coal dust and a nitrogenous gas, with or without a reducing gas, may be blown into or sucked through molten alumina, or the liquid alumina in an atmosphere of nitrogen, may be caused to flow across carbon having a large surface, the operation in either case being effected in an open or closed are or resistance furnace. The alumina may be prepared by melting in an electric furnace a mixture of aluminous material and carbon or aluminous material, carbon and iron or ferric oxide. Alkalies if present are volatilized, and silica &c. is reduced and combines with the iron forming compounds such as ferro silicon, which separate from the fused alumina.  The following raw materials are mentioned: impure alumina, corundum, bauxite, burnt alunite, aluminium silicates such as feldspar and mica, and red bauxite.  In the last case, pig iron may be obtained as a by-product.  The production of the alumina is preferably not effected in the furnace in which the nitride is produced.ALSO:Aluminium nitride is obtained by passing nitrogen into pure molten alumina in presence of a reducing agent such as carbon or a reducing gas or vapour while electric energy is supplied to maintain the temperature.

Title: Process and apparatus for the continuous production of soap in extruded form direct from the raw material
IPC: C11D13/00
Filed: 1947-02-26
Abstract: In the continuous method of manufacturing soap directly in extruded form, wherein the process comprises four successive phases, saponification, glycerine extraction, cooling and mixing, together with homogenisation and pressing, the working temperature being reduced <PICT:0633138/III/1> in each successive phase from the first to the fourth, the raw materials are separately heated to a certain temperature which lies below the saponification temperature and are then combined, mixed and saponified in a single saponifier without additional heating.  In a suitable plant for effecting the process, the preheated fat from a reservoir 1 is pumped through a meter 3 and a further heater 4 to a saponifier 5 together with a similarly treated alkali solution from a reservoir 6.  The temperature of the preheated materials of about 150-200 DEG  C. is further raised by the reaction heat in the saponifier and the latter is maintained under superatmospheric pressure so that the saponification occurs rapidly and completely without evaporation of the glycerine formed and the reaction water.  The saponifier is provided with a worm for mixing the materials and also for conveying them from the inlet to the outlet.  The fluid soap then passes through a valve to a glycerine-extracting column 11, maintained under a vacuum, wherein it flows down inclined plates to collect at the lower part, the glycerine and water vaporizing and collecting in the upper part for discharge and separation.  Owing to the evaporation, the temperature in this second phase of the process drops.  From the column 11, the water and glycerine-free soap is continuously fed to a cooling and mixing apparatus 13 for the third phase of the process.  The apparatus is provided with a conveying and stirring mechanism, and is kept under atmospheric pressure with jacket cooling, the soap being thoroughly mixed therein and cooled down to about 90 DEG  C.  Fillers &c. may be added herein.  The soap is finally pumped, for the fourth phase of the process, to a homogenizing and pressing apparatus 18. The latter is also provided with jacket cooling, the soap being received in solid extruded form at a temperature of about 45 DEG  C. The heating of the various units is effected with electrically heated and automatically controlled heating oil.  Specifications 471,172 and 487,399 are referred to.
