Filed: 1925-04-20
Abstract: 232,635. F÷ttinger, H. April 19, 1924, [Convention date]. Fluid - friction vibration-dampers.- In a fly-wheel of the type containing liquid, the liquid, preferably of high specific gravity, is contained in cells which communicate by restricted openings in such a manner that the liquid can flow from one cell to another under the influence of its inertia. The liquid may be subjected to gas or vapour pressure, and the fly-wheel may be cooled, e.g. by means of jackets. The device, which is particularly applicable for internal-combustion motors, may be combined with the ordinary fly-wheel. The cells 6, 6<1>, 6<11>, Fig. 1, may be arranged in ring form and communicate by openings 11, alternately as opposite sides of the wheel. Radial passages 12 communicating with the arms may be formed in one or all of the spokes of the fly-wheel. The cells may be of rectangular. round or polygonal section. In a modification, Fig. 5, the cells are arranged in pairs of U-form, the liquid oscillating from one leg to the other. The pairs of cells may communicate by openings 11. The frequency of the oscillations of the liquid may be arranged to be the same as that of the torsional vibrations of the shaft at critical speeds.

Patent GB-108175-A (GB)
Title: Improvements in and relating to Speed Indicators or Revolution and like Counters.
IPC: G06M1/04
Filed: 1916-07-20
Abstract: 108,175. Eastern Telegraph Co., and Phillips, B. E. July 20, 1916. Periodic-counter speed-indicators of the kind in which at each operation, occurring on the manual release of a timing mechanism, a counter driven or controlled by a shaft &c. is freed and operated during a period which is determined by the cleck. One or more stops are provided and are maintained out of contact with both the counting and timing mechanisms during the predetermined period. In the form shown in Fig. 1, a clockdriven disk i is prevented from rotating by a spring-supported bell-crank lever m, a projection on the arm of which is removed from a pin k on the disk on the manual depression of a push r, the disk being then free to rotate until again stopped by the engagement of the pin and lever. Rotation of the disk i withdraws a tooth 8 from a projection 7 carried by an arm 6 mounted on the shaft x of an anchor w and allows pallets w<1>, w<2> to be rocked by a spring-controlled slide z reciprocated by the shaft &c., the revolutions of which are to be measured. The escape-wheel t is driven by a spiral spring, (not shown), and carries the first wheel of a counter having frictionallymounted numeral disks and provided with singletoothed transfer mechanism. Until the tooth 7 is freed by the rotation of the disk i, movement of the pallets consequent on the reciprocation of the slide z is insufficient to free the escape wheel. In a modification, the pallets may be operated by a cam on the revolving shaft. To allow the counting operation to extend over part only of the revolution of the disk i, the device shown in Fig. 5 is provided wherein disks 35, 36 are mounted to slide on the shaft 37 of the disk i but compelled to rotate therewith by pins 38 passing through all the disks. The disk 35 bears a projection 8<x> diametrically opposed to the pin 8 so that, when the disk 35 is moved into position, the pin 8<x> stops the shaft after half a revolution. Three projections are arranged on the disk 36 so that the shaft may be stopped after a quarter of a revolution. In the modification shown in Figs. 6 and 7, the reciprocating bar 45 is provided with a spring pawl adapted to engage a ratchet wheel t<x>, and is lccked in the inoperative position by a catch 43 engaging a notch in the bar. The catch is carried by a blade spring 40 attached to a slide 42 and is pressed into its locking position by a pin 41 on the disk i. Two notches 47, 48 are provided in the spring so positioned that the notch 47 allows the pin 41 to pass only when the slide 42 has been moved to the left by the depression of a bell-crank lever 49, and the notch 48 permits the pin to pass when the spring 40 is in its normal position. The passage of the pin 41 through the first notch allows the end of the spring 40 to move up against a stop 60 thus freeing the rod 45. On the completion of a revolution, the catch 43 is forced into the operative position by the pin 41.

Filed: 1968-03-05
Abstract: 1,173,544. Rotary positive displacement I. C. engines. M. W. ROTARY (INTERNATIONAL) DEVELOPMENT PTY. Ltd. March 5, 1968 [March 13, 1967; April 18, 1967], No.10543/68. Heading F1F. A rotary positive displacement I. C. engine includes a rotor 3 lodged between a pair of rotors 2, 2<1> and separated therefrom by intermediate walls 12, 12<1> of a casing that is furnished with peripheral walls 4, 4<1>, 5, the rotors 2, 2<1> being employed to compress air, or fuel and air mixture, while the rotor 3 is driven by expanding products of fuel combustion so as to drive a power output shaft 1 to which each rotor is fixed. Each of the rotors 2, 2<1> carries a spring-loaded vane 8 and is engaged by a similar vane 10 that is lodged in the wall 4, or 4<1>. The rotor 3 is generally similar to each of the other rotors saving that it has two vanes 9, 9<1> and is engaged by two vanes 11, 11<1>. On the leading side of each of the vanes 8, 9, 9<1> a cavity 24, 13 or 13<1> is formed in the respective rotor such that during operation of the engine it periodically comes into register with a transfer port 17 in the adjacent wall 12, or 12<1>. An inlet port 14 is formed in each of the walls 4, 4<1> and an exhaust outlet port 15 is provided in the wall 5. In operation, air, or said mixture, is drawn into a working chamber 6, or 6<1>, associated with each of the rotors 2, 2<1>, and after undergoing compression is transferred to a space 19 adjacent the vane 11 through the corresponding cavity 24, the adjacent port 17 and the cavity 13, or 13<1>, the rotors 2, 2<1> being arranged to operate in antiphase relationship with each other so that they supply compressed air or mixture to the said space alternately and in phase with the movement of the vanes 9, 9<1> through the region of the vane 11. The fuel is ignited by a spark-plug 16 and the combustion products are expanded in a working chamber 7. A space or well 20 is charged with oil mist to effect lubrication and cooling of the piston, means (not shown) being provided for preventing compression of gases in this space by the vanes 9, 9<1>. When air only is inducted through the ports 14, fuel is injected into the space 19 through a nozzle 18. In a modification, Fig. 5 (not shown), each of the inlet ports 14 is formed in a member (25) that can be slid circumferentially of the respective wall 4, or 4<1>, so as to change the position of the port relative to the adjacent vane 10 and thereby alter the compression ratio accordingly. The engine may be adapted for compression-ignition of the fuel.

Title: Control system for hydraulic apparatus
IPC: B30B15/16
Filed: 1954-04-12
Abstract: 754,959. Electric selective control systems. DENISON ENGINEERING CO. April 12, 1954 [April 21, 1953] No 10708/54. Class 40(1) [Also in Group XXIX] A reversible fluid pressure motor is controlled by a directional control valve, the spool of which is displaced proportionally to the current flow in the actuating solenoid therefore, this current flow being regulated by marginally operated relays the supply to which is controlled by variable resistors adjusted by the motor The invention is described as applied to a hydraulic press in which the normally retracted ram 25 is advanced rapidly for the first portion of its stroke and then at a reduced rate, andis automatically retracted from a predetermined position. To initiate an operating cycle of the press a start switch 68 is momentarily closed to energize the start-relay 46 which in turn operates a relay 47. Relay 47 locks and energizes the operating coil 38 over an adjustable resistor 87 to move the spool 30 of the control valve 20 to the right. Fluid pressure is thereby admitted to the top of the cylinder 23 to advance the ram 25 at a rapid rate. The ram, as it moves adjusts through a mechanical linkage 60, potentiometers 53, 54, 55 to vary the current flow in relays 50, 51, 52 which are preset by potentiometers 61-63 so as to operate sequentially as the ram is advanced (downwardly) to predetermined positions. The operation of relay 50 has no effect during forward movement of the ram but when relay 51 operates, relay 47 falls off and the energization of coil 38 is now effected over contacts 97, 88 and a resistor 92, adjusted so as to reduce the current flow in coil 38 and hence to reduce the rate of ram advance. When the ram advance energizes relay 52, a relay 48 is energized. This de-energizes the coil 38 and energizes coil 40 over a resistor 102 to move the spool 30 to the left whereby the ram advance is stopped and its retraction started. The retraction speed is set by the resistor 102 and retraction continues until the relay 50 is de-energized by the ram movement to release relay 48 when the spool centralizes under spring bias to stop the ram. By closing a switch 74 the start relay 46 locks when operated and causes continuous cycling of the system until a stop switch 70 is opened.

Title: Improvements in colour television transmitters
IPC: H04N9/04
Filed: 1944-06-05
Abstract: 598,537. Television transmitters ; electron multipliers. GENERAL ELECTRIC CO., Ltd., and WALTER, D. O. June 5, 1944, No. 10757. [Classes 39 (i) and 40 (iii)] In a colour television transmitter, in which signals generated by a photo-electric device and corresponding to two or three component colours are produced in sequence and are amplified by an electron multiplier, the magnification produced by the multiplier is periodically changed in synchronism with the colour changes by a circuit arrangement for applying to one or more secondary emission electrodes of the multiplier a control voltage serving to vary the mean potential of such electrode or electrodes without varying in opposite sense the mean potential of another secondary emission electrode of the multiplier. As shown, the light is incident on a photo - electric cathode 2 of the electron-multiplier 1, the output of which is derived from a resistance 9 connected between the final electrode 8 and an anode 10. The secondary electrodes are connected to points on a potentiometer 4 connected to earth at 5 and to a terminal 6 at negative potential. Biassing voltages of square waveform and different amplitudes and having a period equal to that of a colour field are applied in succession through blocking condensers 15, 16, 17 to separate electrodes of the multiplier. The voltages which are preferably adjustable independently may be combined and fed in succession to one or more electrodes. In an alternative arrangement, signals derived from a photo-electric mosaic screen are fed to the control grid of an electron multiplier having a thermionic cathode. Specification 568,326 is referred to.
