Title: Improvements relating to oil-sealing means for rotary-piston engines
IPC: F01C19/08
Filed: 1962-03-16
Abstract: 929,770. Rotary piston internal-combustion engines. DAIMLER-BENZ A.G. March 16, 1962 [March 22, 1961], No. 10267/62. Class 110 (2). A rotary piston internal-combustion engine of the trochoidal type includes metal oil-sealing discs 10 having radially inner flanges 9 secured to boss portions 8 of a piston 4 mounted on an eccentric 3 of a driven shaft 2 and radially outer sealing edges 11 sealingly engaging side walls 7 of the engine housing to prevent oil from the bearings getting into the working chambers of the engine. The discs 10 of diaphragm form progressively decrease in thickness radially outwards from the flanges 9 and may be initially deflected to provide close sealing contact with the side walls 7. Lip seals 12 fitted to the side walls sweep the discs and wipe away excess oil. Oil outflow passages 15 radially inwards of the lip seals 12 communicate through ducts 18 in the piston 4 with pistoncooling chambers 19. Except for small gaps 21 the discs 10 cover annular spaces 20 between the cooling chambers 19 and the flanges 9.

Title: Improvements relating to sealing devices
Inventor: DAVIES DAVID OMRI
IPC: F01D11/06
Filed: 1959-03-25
Abstract: 873,651. Stuffing-box substitutes; engine stop-gear; gas-turbine plant. ROLLS-ROYCE Ltd. March 18, 1960 [March 25, 1959], No. 10353/59. Classes 110 (3), 122 (4) and 122 (5). The failure of seals 17, 18, Fig. 3, which allow a restricted flow from a high-pressure region 14, forming part of a duct communicating with a supply means, to a low-pressure region is detected by a control device 20, Fig. 2, comprising a pressure-responsive member 23 opposite faces of which are respectively subjected to the pressure in the high pressure region (which is dependent upon the effectiveness of the seals) and the pressure at the supply means or to pressures functionally related thereto and which is adapted to operate a device to indicate failure of the seal and/or control operation of the apparatus. The invention is shown incorporated in a gas-turbine comprising a high-pressure stage 16, 19, and two low-pressure stages 51, 64 and 53, 65. Cooling air from a compressor is supplied through the duct 14 to cool the turbine disc 16 and passes through seals 17, 18 to seal the hot gas stream passing the turbine blade 19. The seals may be of the labyrinth type or of the self-clearing type in which, when its stator and rotor components touch, clearing occurs by expansion caused by frictional heating. Failure of either or both of these seals would cause a drop in pressure of the cooling gas and allow the hot gases from the turbine to overheat the turbine disc. The control device 20 has chambers 21, 22 separated by a diaphragm 23 and supplied through pipes 26, 24 with gas from, respectively, the delivery side of the compressor and the part of the duct 14 adjacent the seals. The pipe 26 incorporates a restriction 27 to reduce the pressure in chambers 25, 21 to one suitable for operation of the diaphragm 23. The chamber 25 communicates by way of a restriction 30, closable by a solenoid-operated member 33 for testing purposes, with a chamber 31 connected by a pipe 32 to the jet pipe of the gas-turbine or a vent. Upon failure of a seal, the pressure in the chamber 22 drops and the diaphragm urges contacts 42, 43 to make and so close the circuit 45 which may incorporate a warning lamp 46 and/or equipment adapted to operate a pneumatic servomotor to shut down the engine; the device 20 is arranged to give warning of seal failure before such failure results in the in-flow of hot gases. The cooling stream to the discs 51, 53 is provided with seals 50, 52 which are similar to the seal 17 and are arranged. upon failure to light the lamp 46, or a number of control devices may be provided, each connected by a pipe 24 to aposition adjacent the respective seal. Cooling air which has passed through the seals 50, 52 passes via seals 60, 63 into the hot gas stream. The seals 17, 18 instead of controlling the flow of cooling air on to the turbine blades may also or alternatively be used on the front and centre bearings of a gas-turbine engine.

Filed: 1961-03-22
Abstract: 987,931. Photo-electric headlamp control. T. KIKUYAMA. March 22, 1961 [April 2, 1960], No. 10477/61. Heading G1A. A vehicle headlamp switching system comprises a first photo-cell receiving light from a distant approaching vehicle, a second photo-cell receiving light from the approaching vehicle as it passes, means for switching the headlamp to low beam when the first photo-cell is illuminated, a holding circuit and an amplifier, initially receiving current from said first photo-cell and subsequently from said holding circuit. Photo-cell 42, Fig. 1 receiving light from straight ahead is connected at X, Fig. 2 and cells 41, 43 receiving light from passing traffic are connected at Y. When cell 42 is energized, the modulator TM-1, TM-2 modulates the output of an oscillator OSC. The modulated output is amplified by transistor T-1, rectified by transistor T-2 and energizes a relay RL-1. The relay RL-2 is similarly energized on illumination of photo-cells 41 or 43. A switch, Fig. 3, (not shown) is connected at Z for manual headlamp control. Energization of relay RL-1, Fig. 4, closes contacts 5, 6 to energize relay LR which switches the battery B from across the high beam filaments HF to the low beam filaments LF. Transfer of armature 2 from contact 1 to contact 3 switches a capacitor C7 from a charging position across battery B to the amplifier input X into which it discharges to hold relay RL-1 for a preset time. Energization of relay RL-2 breaks the holding circuit so that unless RL-1 is energized by lights from another approaching vehicle the lamps return to high beam. A capacitor C8 is applied to amplifier input Y to hold relay RL-2 for less than 1 sec. In a modified circuit, Fig. 5, (not shown) the headlamps are not returned to high beam as soon as light falls on cell 41 or 43, but only when the illumination of cell 42 also falls to a predetermined level. Reference has been directed by the Comptroller to Specification 858, 968.
