Filed: 1954-02-09
Abstract: 774,578. Automatic gain control. PYE, Ltd. Feb. 1, 1955 [Feb. 9, 1954], No. 3780/54. Class 40(5) In a television receiver the demodulated video wave, with the synch. pulses positive-going, is applied over a condenser C1 to a clamping circuit comprising a pair of diodes V1, 2. The diodes are rendered conductive during the " back porch " period by pulses derived from the line timebase over a transformer T. Alternatively the pulses may be derived from the frame timebase during the post-frame synch. suppression period. In either case the waveform is clamped at black level and is applied to the grid of a valve V3 which is biased by means of a potentiometer P1 as to be conductive only during the positivegoing synch. pulse periods. Negative-going pulses of amplitude proportional to the amplitude of the synch pulses appear across the anode resistor of the valve V3 and are rectified by a diode V4 and smoothed to constitute the A.G.C. voltage. Specifications 715,331 and 774,579 are referred to.

IPC: B66B5/18
Filed: 1918-03-08
Abstract: 121,553. Waygood-Otis, Ltd., and Hildred, C. W. March 8, 1918. Cage and platform lifts; safety retaining-mechanism. -Safety suspending-apparatus for an inclined lift comprises a pump actuated by the movement of the lift which normally circulates fluid idly but upon the breakage or undue stretching of a hoisting rope actuates a plunger geared with a rail gripping device. The plunger 1 of the pump is driven from the axle of the lift and normally circulates fluid through the suction pipe 4, delivery pipe 5, and tank 2. A valve 3 controlled by the hoisting ropes 23 normally prevents communication between the pipe 5 and a pipe 6 leading to one or more plungers 7 provided with racks 14 which gear with pinions 15 on a shaft 16 carrying oppositely threaded rail grippers 17, 18. The stem 8 of the valve 3 is pressed upwards by a spring 10 and is pivotally connected to one end of a pivoted lever 9, the other end of which is held down by a trip lever 12 against the upward pressure of a spring 13. The hoisting ropes 23 are secured to the ends of a lever 24 which is pivoted at its centre in a draw-bar 26 provided with a spring 28. When the lever 24 is rocked by the breaking or stretching of one of the ropes 23, it bears against one of the stops 22 on the rod 21 and the longitudinal movement of this. rod removes the trip lever 12 from its seat on the lever 9. The spring 13 then rocks the lever 9 and the valve 3 being opened, fluid passes to the plungers 7 and the rail-gripping device is applied. If both ropes break, the spring 28 pulls the drawbar, 26 into contact with the upper extension of the lever 12. Undue acceleration may be prevented by connecting the main drum at the top of the track through worm gearing to an electric brake and motor.

Title: Improvements relating to exhaust gas turbines
IPC: F01D25/30
Filed: 1956-02-09
Abstract: 825,286. Gas turbines. DAIMLER-BENZ A.G. Sept. 9, 1956 [Feb. 9, 1955], No. 4110/56. Class 110 (3). [Also in Group XXVII] An exhaust gas turbine associated with a multi-cylinder internal combustion reciprocating engine in which the gas feed to the rotor is divided into several segments each associated with an individual cylinder or group of cylinders by a separate supply duct comprises a plurality of diffusers after the rotor equal in number to the said spaces or segments, the arrangement being such that the major part of the flow of each supply duct, after passing through the rotor, flows through a respective diffuser. The exhaust pipes from groups of cylinders of an internal combustion engine are fed to the inlet manifold of an exhaust gas turbine 10. The inlet manifold is divided by a number of partitions 20, 21, 22, 23, Fig. 4, into a number of segments I to IV each of which are connected to an exhaust pipe. An annular diffuser space 15 after the turbine rotor 12 is subdivided by a set of partitions 16, 17, 18, 19 corresponding to the partitions 20 to 23. The partitions 16 to 19 are displaced in the direction of rotation to the partitions 20 to 23 by an amount corresponding approximately to the distance travelled in the peripheral direction by a gas particle passing through the blading. The main diffusers I to IV may be separated by one or more transitional diffusers 24, Fig. 6, to avoid interference during operation between the main diffusers. Some of the diffuser partitions may be formed as webs 25 to support the bearing 26. Others may be used to supply lubricating oil, sealing air of cooling water to the bearings. In a modification the webs 25 are faired and the bearings supports are passed through slots cut in them.

Filed: 1958-02-07
Abstract: 845,461. Cathode ray oscilloscopes, valve saw-tooth and step wave generators. B.P.L. (INSTRUMENTS) Ltd. Sept. 15, 1958 [Feb. 7, 1958], No. 4116/58. Classes 40(6) and 40(7). [Also in Group XXXVI] An oscillioscope arrangement for displaying successive occurrences in the cycle of an internal combustion engine in vertically displaced relation comprises a staircase vertical deflection wave generator, in which the stairs are initiated by the pulses appearing in the distributer input lead, and a horizontal time base which is triggered in synchronism with the firing of each sparking plug. In Fig. 1, a pick-up associated with the distributor input lead provides pulses which trigger a circuit B on the occurrence of each spark, while a pick up associated with cylinder number 1 triggers a circuit F in synchronism with the spark in that cylinder. Each pulse output from trigger circuit B produces a step in the output of a staircase deflection wave generator C while each output from the trigger circuit F returns the staircase wave to its bottom stair so that the number of stairs in each wave corresponds to the number of cylinders. The output of the staircase wave generator and the voltage picked up from the distributer lead are mixed in the amplifier D to produce the Y deflection on the tube. A further output from trigger circuit B is used to operate a linear time base generator G providing the X deflection on the tube, the amplitude of the time base voltage being automatically maintained constant with changes in engine speed. A further output from trigger circuit F operates an engine speed indicator K. The staircase wave generator (Fig. 4) comprises a "diode pump" circuit C1, C2, X1, X2 which incrementally charges capacitor C2 upon the occurrence of each trigger pulse applied to capacitor Cl, the staircase wave being returned to zero when a pulse applied through capacitor C3 causes the valve V1A of a cross coupled pair V1A, V1B to become conductive and so discharge capacitor C2 through its grid circuit. The linear time base generator (Fig. 5) comprises a capacitor C5 which is charged linearly through resistors R5 and R6 and discharged through the grid circuit of the first of a pair of cross coupled valves V3A, V3B on the occurrence of a pulse applied through capacitor C6. The voltage across the cathode resistors R8 and R9 is applied to a rectifier circuit C7, X3, C4 to control the anode resistance of valve V2 in dependence upon the discharge current flowing through the circuit so that the charging voltage of capacitor C5 is adjusted to maintain the amplitude of the sweep wave generated across C5 constant with changing repetition frequency due to changes of engine speed. In the complete circuit (Fig. 6 not shown) the trigger circuits B and Fare cross coupled pairs of valves and are preceded by diode limiter circuits arranged to limit the input pulses from the distributer and sparking plugs to provide constant amplitude pulses.
