Abstract: 628,448. Fluid-pressure servomotor-control systems. FELL, L. F. R. Oct. 13, 1947, No. 27428. [Class 135] [Also in Groups XXVI, XXVII and XXXIV] At least two compressionignition engines A, B, supercharged by a compressor 2 driven by an independent engine 3, are connected to the sun wheels 26, 27 of a differential gear, the planet carrying member 30 of which is connected to the output shaft. As shown, two further engines C, D are similarly connected and the output shafts are connected to the sun wheels 32, 33 of a further differential gear, the planet carrying member of which is connected through a shaft 42 and a reversing gear to the driving-wheel axle 35 of a locomotive. The engines 3, 8 also operate by compressionignition and the fuel pumps thereof are controlled inversely as the speed of the main engines by a governor having variable spring control. Each fuel pump control rod 48 is moved by the linkage shown in Fig. 3. A piston 53 is subject to lubricant pressure acting through a connection 55a and, if the lubricant pressure should fail, a spring 54 and a floating lever 50 allow the rod 48 to cut-off the fuel supply. During steady motion, the control rod 48 is moved by a piston 56 subject to liquid pressure, e.g.. that of the lubricant, operating through a port 65 and controlled by a valve piston 63, which is moved by boost pressure acting on a piston 72 or by a centrifugal governor 84. The governor weights operate through a rod 87 on a valve 100 which admits pressure liquid to move a slave piston 97 coupled to a floating lever 80. The pressure liquid may be supplied by a gear pump driven by the governor shaft, and located in a casing enclosing the governor weights. The weights are loaded by four springs 89, 90, 91, 92 which come into action in succession as their abutment piston 93 is moved to the right in slave fashion by pressure fluid admitted by a valve 116. In the case of the main engines these valves are operated manually by links 130, Fig. 1, from a lever 128, but in the case of the compressor engines 3, 8 they are operated by boost pressure acting on a piston attached to the valves to maintain constant boost pressure, but relief valves 6, 11 and an isolating valve 12a are also provided. An over-riding manual control for the fuel pumps may be provided.

Title: Improvements in or relating to methods of and equipment for vacuum drying of continuous strip or sheet materials
IPC: F26B5/04
Filed: 1962-07-20
Abstract: 935,063. Vacuum drying strip material. CHAMBON Ltd. July 20, 1962 [Aug. 7, 1961], No. 27989/62. Class 34 (1). In apparatus for the vacuum drying of continuously advanced strip or sheet material, the material passes through a vacuum chamber and jets of fluid under pressure are injected through the orifices through which the material enters and leaves the chamber in directions towards the outside of the chamber and in the proximity of the material, the jets being by an aspirator effect, capable of causing a fall in pressure within the chamber and also of opposing the admission of the surrounding atmosphere into the chamber. A web 2 is dried by passage through a chamber in which a vacuum is created by an aspirator effect from jets of compressed fluid issuing from nozzles 5 arranged near inlet 3 and outlet 4 of the chamber. The jets of fluid induce currents both between each nozzle and the web and also between each nozzle and the adjoining chamber wall which prevent the admission of ambient atmosphere to the chamber. The chamber wall may be flared towards the outside so as to form a convergent-divergent passage with the nozzles, or one side of the end of each nozzle is connected in air-tight manner to the chamber wall so that the aspirator effect is only produced between the nozzle and the web. Supplementary means, e.g. a source of vacuum, may be connected to the chamber.

Title: Aircraft ejection seat catapult
IPC: B64D25/10
Filed: 1959-08-19
Abstract: 869,486. Aircraft ejection seat guns. GABRIEL CO. Aug. 19, 1959 [Feb. 3, 1959], No. 28354/59. Class 4. An aircraft ejection seat gun comprises a tube 20 fastened at one end to the aircraft, a rocket motor assembly 102 slidable in the tube and secured to the seat, e.g. by a forwardly extending member 170, a rocket motor cup 96 slidable in the tube 20 and separably connected to the nozzle end of the assembly 102, a propellant charge 62 in the tube behind the cup, and firing means therefor, means to release the cup from the assembly 102 when the assembly is propelled outwardly by hot gas generated by the charge, and means for exposing fuel in the rocket to hot gas on separation of the cup from the assembly, so as to ignite the rocket fuel just prior to separation of the assembly from the tube. Fig. 4 shows the upper part, and Fig. 3 the lower part, of a gun. To eject, -the seat occupant pulls on a line 208 attached to his face blind, and removes a sear 204 to release a firing pin 148 to denoate a percussion cap 146 and gas generating charge 144, this apparatus being mounted in a block at the top of the sliding tube 110 of the rocket assembly. The generated gases pass through ports 156 and manifold 160 to a pipe 220 containing quick release couplings 226, Fig. 4, and 228, Fig. 3, which separate under tension when the rocket assembly and seat start to rise. The gases pass from pipe 220 to a chamber 232 in the fixed tube 20, and operate a firing pin 70, to fire a percussion cap 78, ignition charge 80, and the main propellant charge 62 in a cartridge 60. The rocket motor cup 96 comprises a disc 100 acting as a piston, and a wall slidable over the assembly 102, and is normally fixed in tube 20 by tines 92 engaged between a shoulder 94 on a liner 54 fixed in tube 20, and a shoulder 90 on cartridge 60. When charge 62 is fired, the resulting gas pressure forces the cartridge down, compressing spring 234. This releases the tines 92, and the cup and rocket assembly are propelled upwardly by the compressed gases. The cup is normally secured to the assembly 102 by tines 130 engaged in a groove 132 by a collar 126 held in place by a shear pin 128. In the course of the upward movement, collar 126 strikes a shoulder 134 in tube 20. Pin 128 is sheared, and the collar displaced, releasing tines 130. The rocket assembly separates from the cup, and withdraws plugs 122 from vents 120 in the cup disc 100. The hot gases can now enter the rocket nozzle 114, and ignite the rocket charge 112, which continues to. propel the seat upwardly, the axis of the rocket nozzle passing approximately through the centre of gravity of the seat and occupant. To ensure firing of the rocket at low temperatures, hot gases may pass from the cartridge by means not shown, to ignition material 161, Fig. 4. The fixed tube is attached to the airframe by bolts 28, Fig. 3, and 32, Fig. 4. The seat is guided initially by having slides engaging rails secured to or formed in the exterior of tube 20. Specification 832,849 is referred to.

Title: Method of and arrangement for avoiding the cross-current error in braun tubes
IPC: H01J29/74
Filed: 1933-10-16
Abstract: 431,773. Television ; cathode ray tubes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and SCHLESINGER, K., 39, Friedrichstrasse, Friedrichshagen, both in Berlin. Oct. 16, 1933, No. 28502. Convention date, Oct. 17, 1932. [Classes 39 (i) and 40 (iii)] In a television arrangement including a Braun tube with two main deflecting plate systems for causing the ray to scan the picture screen, the scanning potentials are applied only to one plate 3 of each system, the other plate 4 is connected to earth through a condenser 7 and biassed so that it is always positive with respect to the plate 3, and the ray enters the space between the plates 3, 4 along a line touching or intersecting the plate 3 preferably near its centre. Instead of inclining the anode 2 as shown, the ray may be given a constant deflection between the anode 2 and the deflecting plates as described in Specification 420,752. The resistance between the plate 4 and earth is kept small, but the resistance of the generator 5 of deflecting potentials may be large. Any electrons flowing to the deflecting plates go to the plate 4 and not to the plate 3, and the arrangement thus avoids the "cross current error," i.e. accidental variations of the deflecting plate potentials due to electron flow to the plates and to the resistance of the plate circuits.
