Title: Improvements in or relating to thermionic oscillation generator circuits
IPC: H03L1/00
Filed: 1936-05-22
Abstract: 475,530. Valve circuits for generating oscillations. STANDARD TELEPHONES & CABLES, Ltd., JACOBSEN, B. B., and TERRY, V. J. May 22, 1936, No. 14549. [Class 40 (v)] Variations in the frequency of currents generated by a thermionic oscillator circuit with variations in the supply current are prevented with the circuit shown in which the primary of the feed-back transformer 7 is tuned and directly connected to the grid of an amplifier valve 4 and is coupled to the anode circuit of the valve 3 through a condenser 9 and resistance 8 by arranging that the ratio of the transformer is such that the amplitude of the oscillations generated is limited by the flow of grid current in 4 which takes place at a lower amplitude than that at which grid current would flow in 3, and providing a small variable condenser 15, settings of which can be found experimentally which make the frequency generated independent of variations in the sources of supply 2, 1. Usually, these settings are different, but if the transformer 7 includes a core of a material such as soft iron dust, the permeability of which varies with frequency, circuit settings can be found that give frequency stability with variations in both sources of supply. A further advantage of such a core is that its temperature coefficient may compensate that of the main condenser 10. In a modified circuit, Fig. 2, in which the oscillator valve 3 is biassed by a grid leak instead of by a resistance in the heating circuit, an adjustable condenser 17 for giving stability is provided in shunt to resistance 8 and optionally a resistance 25 is included in series with 15. Where it is found that negative values of capacity are required for the condensers 15, 17 to give the desired result, they are connected instead at 17a and 15a. The Specification indicates the relative values of some of the circuit elements.

Patent GB-437899-A (GB)
Title: Improvements in or relating to fuel injection systems for internal combustion engines
IPC: F02M63/04
Filed: 1934-05-16
Abstract: 437,899. Fuel - injection systems. CONTINENTAL MOTORS CORPORATION, 12801, Jefferson Avenue, Detroit, Michigan, U.S.A.-(Assignees of Vincent, E. T.) May 16, 1934, No. 14782. Convention date, Dec. 21, 1933. [Class 7 (iii)] [See also Group XXVIII] In a multicylinder internal-combustion engine, the injection valves are opened in timed relation with the engine by fuel pressure, are closed automatically when the fuel pressure diminishes, and are held closed by loading-means. A fuel pump begins to deliver fuel to a common supply line after the loading-means have been applied to the valves, and ceases delivery either before the valves open or shortly thereafter. No fuel is delivered at least during the last 75 per cent of the fuel-injection period. As shown in Fig. 1, a pump 35 having a constant stroke delivers fuel into the common supply line 37, which includes an adjustable pressurerelief device 40 to determine the pressure in the pipe line. Branch pipes 38 connect the pipe 37 to the injection devices, and valves 39 allow the supply of fuel to any cylinder to be cut off. The fuel passes through a passage 41, Fig. 3, and grooves 28 in the valve stem to a chamber 45 around the tip of the nozzle. The valve is held on its seat by a heavy spring acting through a rocker arm 30, and by a light spring 44. When an engine-driven cam compresses the heavy spring, the arm 30 is released and the fuel pressure opens the valve. When the fuel pressure falls, the spring 44 seats the valve to terminate the injection, and after the rocker 30 engages the valve stem, the pressure in the line 37 is restored by the pump. During excessive engine loading, the valve may be closed by the rocker 30 before the pressure has fallen sufficiently to allow the spring 44 to close it. Fuel leaking past the valve stem is led away through a conduit 42<a>. In a modified construction, a pump of the variable-stroke type feeds fuel to the pipe line 37. As shown in Fig. 6, a low-pressure gear pump 70 delivers fuel past a filtering-chamber 86 to the inlet valve 82 of a high-pressure pump 77, which delivers past a valve 79<a> into the line 37. The inlet valve 82 is operated by a rocker arm 83 which is actuated by a rod 87 on a stub shaft 89 carried by the pump plunger 76. By moving a lever 92, the time at which the suction valve closes may be varied and the pressure in the pipe line altered. The timing of the end, instead of the beginning, of the effective pump stroke may be controlled.

Filed: 1926-06-15
Abstract: 261,339. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Dean, W. E.). Nov. 13, 1925, [Convention date]. Addition to 236,161. Pressure-regulating valves.-A pressure-regulating device particularly applicable as a feed valve on fluid pressure braking systems and of the kind comprising a main valve controlled by an auxiliary valve and in which a Venturi tube is inserted in the main conduit'for reducing the pressure on the regulating diaphragm to accelerate the action of the device, is provided with further means for limiting the action of the Venturi device. In the form shown in the Fig. the main valve 14 has ports 15, 16 adapted to co-operate with ports 17, 18 to control the flow from a reservoir pipe 13 to the train pipe 7 and is actuated by a piston subject to conduit pressure. Pressure is admitted to the back of the piston through a restricted orifice 23 and is exhausted through an auxiliary valve 8 actuated by train pipe pressure acting on a spring loaded diaphragm 3. The connection to the train pipe is made through a Venturi device 19 so that when the main valve is open the pressure acting on the diaphragm is reduced below that in the train pipe. As, however, the main piston moves to open the main valve it uncovers side ports 21 in the cylinder leading to a bye-pass passage whereby further inlet pressure is admitted to the back of the piston to more or less counteract the accelerating action of the Venturi device. The ports 21 may be of uniform area or increase in area in the direction of outward movement or a single tapering port may be provided. In a modification the ports 21 are dispensed with and a bye-pass passage provided so that only part of the main flow passes through the Venturi device. In a further modification the main actuating piston is fitted with a second loading spring adapted to come into operation when the main valve is partly open.

Title: Improvements relating to the control of plant comprising free-piston machines and turbines
IPC: F02C5/08
Filed: 1942-10-28
Abstract: 561,154. Gas turbine plant. PESCARA, R. P. Oct. 28, 1942, No. 15151. Convention date, Nov. 4, 1941. [Class 7 (i)] [Also in Group XXVI] Relates to a gas turbine plant supplied with working fluid from a free piston gas operator. At low wads and with minimum fuel injection, the generator supplies the necessary quantity of gas at too high a pressure and the pressure is reduced before the turbine by throttling. For larger wads, the appropriate pressure and quantity of gas can be obtained, without throttling, by regulating the fuel injection. In the plant shown in Fig. 1, the fuel injection is controlled by a rod 9, which is extended by a link 9<1>, the free end 9<11> of which rides between the walls 12 of a cam stop. A piston 13 subjected to the delivery pressure of the generator moves the end 9<11> to a level corresponding to that pressure and at the level the right hand wall of the cam stop determines the minimum fuel injection and the other wall the maximum fuel injection for that pressure. A throttle valve 10 is operated by means of a cam 16 from a control rod 18 and the rod 9 is also connected to the rod 18 by a lever 11 having a floating spring controlled pivot. As the wad increases, the rod 18 is moved, either by hand or by a governor 21, and in the early movement the cam 16 opens the throttle but the spring 201 keeps the rod 9 in the minimum fuel injection position. When the throttle is fully open and a concentric portion of the cam 16 rides on the rod 15, movement of the rod 18 causes the rod 9 to move to increase the fuel injection subject to the upper limit imposed by the left hand wall of the cam stop 12. If an excessive pressure is reached, a piston 90 moves the rod 9 to the right and so reduces the fuel injection independently of the control rod 18. A second plant is described in which two forward turbines and one reverse turbine are supplied by one, two or three generators having a unified control.

Filed: 1972-03-30
Abstract: 1391696 Electrolytic grinding HITACHI Ltd 30 March 1972 [2 April 1971] 15240/72 Heading C7B [Also in Division G3] The feed control system of an electrolytic grinding machine has a detecting circuit for detecting a high frequency (spark) signal which signal is used to control the speed of the feed motor. The detecting arrangement is shown in Fig. 2 and consists of a resonant circuit 7, 8 which produces a high frequency signal at 9 whenever workpiece 3 approaches too closely to wheel 5. The signal is amplified, sloped and limited and applied to one input of AND gate 14. The other inputs of the AND gate are provided by the load current, measured by shunt 11, and pulses derived from the full wave rectified working voltage at 17, 18. The resultant intermittent signal from AND gate 14 is representative of the working distance between the wheel and workpiece and is used in the control system shown in Fig. 5, to add or subtract pulses from counter 30. The free counter 33 counts clock pulses from oscillator 34 until both counters are reset by a pulse from amplifier 32. If the counter values become equal the circuit 36 provides a pulse which is used in amplifier 38 to modify the operation of circuit 40 and vary the firing angle of SCR 26 and thus alter the motor speed. When setting up the initial detection is provided by measuring the working current using shunt 11  and the shaping circuit 21, 22 which supplies a signal through AND gate 20 to the control circuit. In a modification, Fig. 4 (not shown), a further resonant circuit can be used to provide the initial detection.
