Title: Improvements in electric supply systems having means for absorbing regenerated power
IPC: H02H7/12
Filed: 1943-02-03
Abstract: 585,660. Protective cut-out arrangements. GENERAL ELECTRIC CO., Ltd., and CROFT, E. H. Feb. 3, 1943, No. 1778. [Class 38 (v)] A protective arrangement for absorbing regenerated power comprises a resistance 8 arranged to be connected across bus-bars 3, 4, so as to absorb power regenerated therein, voltage-responsive coils L1W, L2W operated when the voltage across the bus-bars exceeds a predetermined value so as to insert the resistance, a time-delay relay TS for disconnecting the resistance after a predetermined time, and a forward-current-operated relay PR for disconnecting the resistance when forward-current flows in the bus-bars, the relays TS and PR operating independently of one another. Upon overvoltage, the coils L1W, L2W, are energized through a normally-closed contact lb1 and a regulating resistance 9, thereby closing contacts l1, l2, l12, 122, L1 and L2, and putting resistance 8 in circuit. The relay TS is energized and after a time-delay, contact ts1 opens, thereby deenergizing coils L1W, L2W. Meanwhile, relay PR is de-energized by the reverse-current in the bus-bars 3, 4, to close contact pr1 and energize coil LA. Contacts la1, la2 close and energize coil LB, opening contact lb1 and closing lb2. When forward-current in the bus-bars 3, 4 is restored, relay PR is energized, opening contact pr1 and de-energizing coil LA to open contacts la1, la2, thereby de-energizing coils L1W, L2W, if this has not already been done by the timedelay relay TS. Coils TRS, TRP, are respectively connected in series and parallel with the resistance 8 and operate an indicator contact tr1 should the resistance be overheated.

Abstract: 541,902. Cylinder liners and valve guides ;  valve-gear. THOMPSON PRODUCTS, Inc. Jan. 31, 1940, No. 1941. Convention date, March 20, 1939. [Classes 7 (ii) and 7 (vi)] [Also in Groups XXII, XXVI and XXXIV] Split liners for cylinders, bearings for tappets, valve stems, shafts &c. are made from blanks 11 cut from sheet steel and bent to cylindrical form round a mandril 12, Fig. 2, such that the edges substantially abut at 13a. The sheet is of spring steel and may be Nitralloy. After bending, the edges of the sheet spring apart leaving a substantial gap and the blank is heat-treated and if desired hardened as by nitrogenization. The blank is then inserted in a cylinder corresponding in size with that to be lined and the inside is bored to the required diameter. The cylinder diameter and the internal diameter of the liner when in position may be stamped on the edge of the liner. When in position the gap 14 is not quite closed so that the liner may be further contracted to ensure easy fitting in the cylinder in which it is retained by a flange at 26. In a modification the gap has a helical form and the liner has a flange at its upper end that is received into a counterbore in the cylinder.

Title: Improvements in or relating to internal combustion engines
IPC: F02B19/02
Filed: 1925-01-22
Abstract: 239,427. Renault, L. Oct. 18, 1924, [Convention date]. Cylinders receiving liquid fuel. - An auxiliary charge of carburetted air, compressed in a chamber 2 to a pressure lower than that finally attained on the compression stroke in the cylinder, is ignited immediately before the piston reaches the top dead centre position, and entering the combustion chamber 1 through a valve 3, vaporizes and ignites the main charge of heavy fuel, which is injected directly into the combustion chamber 1 through a nozzle 10, or supplied to a point above the valve 3 and carried into the combustion chamber by the auxiliary charge. The fuel may be supplied by a measuring pump, or drawn into the chamber 2 by the engine. The chamber 2 is charged from a carburettor 17, which in a two-stroke-cycle engine may be supplied with air under pressure by a pipe 18 connected to the scavenging air supply pipe 19. The chamber 2 communicates with the cylinder through a passage 4, which towards the end of the compression stroke is closed by the engine piston 14, so as to arrest compression in the chamber 2 before the final pressure in the combustion chamber has been attained. The valve 3 may be operated either by fluid-pressure or mechanically and opens during the period of ignition only. Starting is facilitated by cutting off the supply of heavy fuel entirely, and by providing means to prevent the compression pressure in the combustion chamber 1 from exceeding that normally attained in the chamber 2. This may be effected in a four-stroke-cycle engine by a release valve in the combustion chamber 1. The engine may be run on the auxiliary charge of fuel alone when idling or at light loads. In some cases, when the engine has warmed up, the auxiliary chamber 2 may be cut out, the fuel being ignited by the heat of compression in the chamber 1; for this purpose a stop valve may be provided in the passage 4.

Title: Improvements relating to inverter power supplies
Inventor: KING KENNETH GORDON
IPC: H02M1/08
Filed: 1963-01-21
Abstract: 987,002. Converting. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Jan. 14, 1964 [Jan. 21, 1963], No. 2498/63. Heading H2F. [Also in Division H3] An inverter is alternately operating and quiescent for periods of time equal to several cycles of the inverter. In the Figure a 50 c/s supply S is rectified by a bridge rectifier 1, filtered by the elements 2, 3, 4 and fed to a storage capacitor 10. A controlled rectifier 7 (of the type which is rendered conductive on application of a firing pulse and only rendered non-conducting when the current tends to reverse) inductance 6 and capacitor 5 are connected in series forming an oscillatory circuit. When the rectifier 7 is fired this circuit attempts to oscillate, and the rectifier is turned off leaving the capacitor 5 charged. The circuit comprising the load 9, inductance 8 and the capacitor 5 is also oscillatory, having a natural frequency which is high relative to that of the first oscillatory circuit, and the energy stored in the capacitor 5 is dissipated at the higher frequency in the load. Control circuit.-The source S also supplies a bridge rectifier 31 in the control circuit. The transistor 13, where collector and emitter electrodes are connected through resistor 18 across the bridge 31, has its base connected through resistors 12 and 15 to both A.C. lines. Consequently whenever the bridge 31 is conducting transistor 13 conducts, and it is only non-conducting at the cross-over points of the supply S. When transistor 13 conducts the voltage drop across resistor 18 is such that diode 19 is reverse biased. Capacitor 21 charges through resistor 20 from the stabilized supply provided by resistor 22 and capacitor 23. When transistor 13 becomes non-conducting diode 19 can conduct, and the capacitor 21 discharges rapidly through resistors 18 and 23. Consequently a sawtooth waveform with a frequency of twice the supply frequency appears at the junction of capacitor 21 and resistor 20. This sawtooth waveform is opposed by a direct control voltage from 33, and when the resultant is negative transistor 25 conducts. A blocking oscillator comprising transistor 26, transformer 28, capacitor 27 and resistor 30 runs as long as the base of the transistor 26 is sufficiently negative, that is when transistor 25 is not conducting. Firing pulses are therefore produced from a variable point in each half cycle of the supply S, until the end, and the average power in the load depends on the control voltage at 33. There may be a feedback system from the load 9 to the control voltage source 33.
