Title: Method of and apparatus for producing artificial threads more particularly multiple filament threads from cellulose solution
IPC: D01D10/00
Filed: 1921-05-13
Abstract: 163,312. Sch³lke, E. May 17, 1920, [Convention date]. Apparatus for making filaments.-The filaments or bundles of filaments 3 issuing from the precipitating bath 4 are passed between rollers 6 surfaced with india-rubber or like elastic material, and from thence to a centrifugal 9 which when full is spun at a higher speed; the rollers act to regulate the drawing-out of the filaments, and the centrifugal, during the time it is collecting, is run at a speed corresponding to that of the rollers, or at a slightly higher speed for the purpose of obtaining an additional stretching; during the subsequent high-speed run of the centrifugal, any portions of the precipitating bath adhering to the threads are separated, and the threads are washed and treated with appropriate bleaching &c. baths, and finally dried by injecting warm air, while the increase of tension resulting from the higher speed of running improves the lustre of the threads. As shown, the threads passing from the rollers 6 are delivered to a conveyer band 7 and from thence through a guide 8 to the centrifugals; these are duplicated in order that the process may be continuous. The rollers, conveyer band, and centrifugals are coupled together so as to maintain the relative velocities of these parts.

Filed: 1974-03-28
Abstract: 1465550 Projectiles VALINOR ANSTALT 28 March 1974 [10 Oct 1973] 13774/74 Heading F3A A projectile comprises a propellant 24 surrounding vent holes 23 in a tail 16, the propellant being ignited when the projectile has already been set in motion by the ignition of a propellant 20. The propellant 20 is contained in a piston 19 and is ignited upon a primer 21 being struck by the firing pin 14 in a launching tube 12. Upon ignition of the propellant 20, the piston moves relatively rearwardly to uncover the holes 23 and to thereby allow the hot gases from the propellant 20 to ignite the propellant 24. A frusto-conical seating 22 in the tail arrests the piston. The section of the tail containing the holes 23 may be surrounded by a sleeve (not shown) containing corresponding holes, the sleeve being rotatable to vent or mask the holes 23 according to whether propulsion by both propellants or only the propellant 20 is desired. Although the projectile has a higher muzzle velocity than conventional projectiles, the pressure in the launching tube is also lower and permits a reduction in the wall thickness of the launching tube.

Title: Control systems
IPC: A61F4/00
Filed: 1961-04-18
Abstract: 1,021,531. Selective signalling. R. G. MALING. May 31, 1962 [April 18, 1961; May 3, 1961], Nos. 14024/61 and 19635/61. Heading G4H. A control system operable by a partially paralysed person comprises an electric transducer responsive to relatively small pressures exerted by the person and means for selecting a required controlled circuit, which means is controlled by the period of operation of the transducer.  In one form of apparatus the operator sucks on a rubber pipe thereby closing a vacuum switch and causing a uni-selector to start stepping. As the uni-selector steps it sequentially lights a row of white lamps so that the operator can see how far it has stepped. Each white lamp corresponds to one of the various devices that can be controlled and has adjacent to it a green lamp and a red lamp one of which is always lit to indicate whether the corresponding device is on or off. When the uniselector reaches the position corresponding to the device that is to be controlled, the operator stops sucking, the vacuum switch opens, and, after a short delay, the operative condition of the device to be controlled is reversed, i.e. if it was on it is turned off and vice versa. The uni-selector then automatically homes. In a second form of apparatus a suction switch and a pressure switch are connected to the operator by a single rubber tube. The control panel is in the form of a rectangular array and the suction switch is closed to select a column of the array after which the pressure switch is closed to select a particular function in that column. A relay which is energized by the suction switch ensures that the pressure switch has no effect until a column has been selected. To assist in selection a different aural signal is given for each column scanned and further aural signals one octave lower are emitted as the units of the column are scanned. The controlled circuits may include a typewriter. In a third form four switches comprising two pressure switches which operate at different pressures, and two suction switches which operate at different pressures, are connected to the operator by a single tube.

Title: Improvements in fuel control systems for jet engines
Inventor: NOON T CYRIL
IPC: F02K3/00
Filed: 1954-05-14
Abstract: 767,662. Automatic control systems. THOMPSON PRODUCTS, Inc. May 14, 1954, No. 14275/54. Class 38 (4). [Also in Group XXIX] In a system for automatically controlling a jet engine, voltages dependent on engine speed and temperature control through electronic apparatus; a solenoid-operated pilot valve which, in turn, hydraulically controls a double landed piston-type throttle valve in the supply from a fuel pump to the engine. In Fig. 1 a D.C. tachometer generator 30 driven by a jet engine 10 is associated with a first bridge circuit of the electronic apparatus to produce a voltage dependent on deviation of engine speed from a value determined by the setting of a hand lever 177 adjusting the bridge circuit. Generator 30 is also associated with a second bridge circuit to produce a voltage dependent on engine acceleration. Thermocouples 62 are associated with a third bridge circuit, the output of which is amplified to produce a voltage dependent on engine tailpipe temperature. In the electronic apparatus one of these three voltages is selected automatically by an electronic selector and is applied through a D.C. amplifier with the addition of differential and integral components to control a solenoid-operated rotary sleeve pilot valve 31. Pilot valve 31 controls a throttle valve 19 in the fuel supply from a tank 14 through pumps 15 and 18 and conduit 24 to nozzles 11. The electronic selector is such that, during starting, the temperature dependent voltage is selected to control the fuel and maintain tail-pipe temperature at a maximum allowable value. When, however, engine speed is within a predetermined percentage of the selected speed, the speed dependent voltage is automatically selected to control the fuel and maintain constant speed. If at any time thereafter the tail-pipe temperature tends to exceed the maximum allowable value it is prevented from so doing by the automatic selection of the temperature dependent voltage to control the fuel. If, during starting, the temperature dependent voltage should fail, the acceleration dependent voltage is automatically selected to control the fuel. Excessive engine speed causes centrifugal contacts 26 to open and de-energize a relay 56 so that a solenoidoperated valve 25 restricts fuel supply. Valve 25 can only be re-set by returning hand lever 177 to an " idle " position and manually closing a switch 59<SP>1</SP>. Hand lever 177 is also' associated with a valve 28 for shutting off the fuel supply. When hand lever 177 is moved from a " start " position to the " idle " position a solenoid 50 is de-energized to withdraw an upper limit stop and permit a greater opening of throttle 19, while a solenoid 51 is de-energized to insert a lower limit stop for throttle 19 corresponding to idling speed. A throttle valve 47 associated with a restriction 42<SP>1</SP> controls the pressure applied to pilot valve 31 and a relief valve 20 by-passes excess fuel to the input of pump 18.
