Inventor: TOWNSEND CHARLES
IPC: C11C3/12
Filed: 1952-02-06
Abstract: 738,746. Electrolytic treatment of liquors containing unsaturated oils. PROTAMIN, Ltd. May 6, 1953 [Feb. 6, 1952], No. 3088/52. Class 41. Aqueous liquors containing oils having unsaturated fatty acid radicals, are electrolytically hydrogenated in the presence of nickel, whereby the oils are converted to saturated fats. Waste liquor from the steam digestion of fish and marine animals is passed through nickel ducts 1 having cathode rods 3 of zinc, manganese, nickel, iron or steel. The ducts are connected by plastic connectors 2 having uneven internal walls, preferably helically corrugated, to produce turbulence; there may also be stirrers at X. When a current is passed making the ducts anodes, the oil is hydrogenated by hydrogen produced at the cathodes to form fats. Before treatment the liquor may have proteolytic enzymes added to reduce proteins present to simpler substances. The liquor after hydrogenation may be concentrated to a paste or spray dried. An alternating current may be used, in which case the rod 3 is made of nickel.

Title: Fuel supply system
Inventor: COWLES WARREN H
IPC: F02K3/00
Filed: 1958-01-30
Abstract: 851,304. Gas-turbine fuel systems. HOLLEY CARBURETOR CO. Jan. 30, 1958, No. 3089/58. Class 110 (3). A main fuel pump 16 delivers fuel from a tank 10 to the main combustion chamber 12 of a jet-propulsion engine through a metering valve 34 and can also deliver fuel to a reheat combustion chamber 14 by way of a throttle valve 106 and a metering valve 114. The metering valves 34, 114 are operated manually by a lever 46 and cams 42, 122 with, preferably, additional automatic control in accordance with compressor discharge pressure and (in the case of valve 34 only) engine speed and engine inlet air temperature. The pressure drop across the metering valve 34 is stabilized by a by-pass valve 64 which is subjected to the pressure drop and returns fuel to the tank 10 through a by-pass passage 60. Further by-pass valves 80 and 90, subjected to the pressure drop across a restriction 72 in the by-pass passage and therefore controlled by the flow through the by-pass valve 64, return fuel to the tank 10 respectively from the main fuel pump 16 and an auxiliary fuel pump 18. The relative strengths of the springs of the valves 80 and 90 are such that valve 90 is fully opened before valve 80 begins to open, so that the auxiliary fuel pump 18 is completely unloaded until the demand exceeds the capacity of the main fuel pump 16 (or a failure of the main fuel pump occurs). Check valves 26, 28 prevent recirculation of the output of one pump through the other pump. The throttle valve 106, subjected in the closing sense to the pressure drop across the metering valve 114, serves to stabilize the flow to the reheat combustion chamber 14. Preferably, an upper limit is set to the pressure drop across the restriction 72 by means of a valve 74, designed to open when the pressure drop reaches a predetermined value.

Title: Improvements in or relating to processes and apparatus for producing a combustible mixture of liquid or colloidal fuel and air
IPC: F02M69/00
Filed: 1933-02-03
Abstract: 416,024. Generating combustion products under pressure. MAINA, J., 35, Maybury Mansions, Marylebone Street, London. Feb. 3, 1933, Nos. 3299 and 20924. [Class 51 (i).] A gaseous explosive mixture for use in internal-combustion engines and burners is produced by (1) highly compressing a substantially inert gaseous fluid so as to raise it to a temperature higher than that at which the heaviest vaporizable constituents of the liquid or colloidal fuel are vaporized ; (2) injecting the said fuel, in a highly dispersed state, into the highly compressed and highly heated gaseous fluid, as near as possible at the highest attainable pressure and temperature of the said fluid thereby forming a non-explosive gaseous mixture and (3) adding air, which may be compressed and heated, in proportions to form an explosive and ignitible mixture. Water or steam may be added at any stage of the process. Nitrogen may be used as the inert gas, but as applied to an engine, the exhaust is used, and a petrol carburetter may be used at starting. A compressor 2, Fig. 1, driven by an independent motor, is fed with hot exhaust gases at 3, the compressed gases being delivered through pipe 2<1>, Fig. 2, into a vaporizing chamber 5<a> surrounded by an exhaust jacket 5b fuel being forced by a pump 4 through a nozzle 4<1> into the chamber 5<a> in a highly atomized state. The mixture of inert gases and fuel escapes past a valve 6 and is conveyed by a pipe 7, Fig. 1, to an annular passage 8 around a Venturi tube 10 to the throat of which it passes through apertures 9. Mixing then takes place with air admitted at 12 and the explosive mixture so formed passes the throttle valve 11 to the engine. At starting, a petrolair mixture may be admitted from a carburetter 12<a>, the change-over being effected by a valve 13. The throttle valve 11 is interconnected with a throttle 11<a> and also with a throttle 15 in the gas passage 7. In a modification, the fuel is injected by the pump directly into the cylinder of the gas compressor. In a further modification, Fig. 4, particularly applicable to burners, the fuel is injected either into the cylinder 2 or the vaporizing chamber 5 which is provided with an independent heating device 5d. The mixture escapes past a valve 17 into a pipe 18 whence it flows into a chamber 19 and then through orifices 30 into a Venturi tube 23 through which air is drawn. The outlet orifice of the pipe 18 is controlled by a valve 26, 25 attached to a spring-loaded piston 24 actuated by the depression in the air passage 20 transmitted through duct 21. In a still further modification, the mixture of hot gases and fuel is conveyed to a nozzle discharging at the throat of a Venturi tube, the inlet to the nozzle being controlled by a valve coupled to an automatic valve in the outlet passage which latter valve is forced to its seat and also closes the nozzle valve in the event of a backfire.

Abstract: 510.460. Fastenings. MALONE, A. J., and THOMPSON, J. A. Feb. 3, 1938, No. 3442. [Class 44] A handle 17 for a vehicle door latch is let into the door and lies substantially flush with the door surface 18, the arrangement being such that one end 26 of the handle can be pressed below the door surface, without the release of the latch being initiated, to raise the other end above the surface to enable it to be gripped, whereupon it can be pulled further out to release the latch. In the arrangement shown, the handle 17 is pivoted at 19 to a spring-biassed lever 20 which has a pin engaging a crank 16 having a lost-motion connection at 31 with the sliding latch-bolt. The initial movement of the handle is swinging about the pivot 19, without affecting the latch mechanism, but when the end 26 of the handle engages the bottom of the recess 30 further pulling out of the handle will operate the mechanism. Operation may be prevented from inside the vehicle by a lever 25 which moves a member 24 behind the end 26 of the handle 17 to prevent it from being pressed in, so that the handle cannot be gripped. A key lock or other means operated from outside the door may be provided to lock the handle in its flush position. In a modification, the end 26 of the handle, after its initial movement bears against the pivot of the lever 20, which may engage the latch-bolt directly. In another modification the handle is pivoted on the bolt, and bears against a fixed pin after its initial movement. In a third form, the handle is mounted on a fixed pivot, and engages the bolt with lost motion.

Abstract: 1,206,162. Baling machines. MASSEYFERGUSON G.m.b.H. 22 Dec., 1967 [25 Jan., 1967], No. 3648/67. Heading B5F. [Also in Division D1C] A twine retainer 6 for use with a knotting mechanism 4 in a baling machine comprises a pair of discs 6A, 6B urged together by a compression spring 10 and a spring-loaded lever 11, the latter being cam controlled by a disc 2 driving the knotting mechanism such that the effect of the lever 11 on the discs 6A, 6B can be varied so that the twine is clamped tightly during the baling operation but only lightly during the knot tying operation. The lever 11 carries a follower running on the cam surface on the edge of the disc 2 such that it is urged to bear on the spring 10 and increase the load on the discs 6A, 6B during the baling operation. When the knotting operation is to be performed, the follower following the contour of the cam allows the lever 11 to release its effect on the spring 10. A certain effect is still maintained by the lever 11 on the spring 10 by a coil spring 17 bearing on the opposite end of the lever 11 and this effect can be adjusted for tensioning during knotting by a nut 18.
