Title: Improvements in or relating to the cam shafts of internal combustion engines
IPC: F02B67/04
Filed: 1920-09-06
Abstract: 172,409. Sunbeam Motor Car Co., Ltd., Coatalen, L., and Irving, J. S. Sept. 6, 1920. Valve-gear. - In order to provide a continuous resistance to the rotation of the cam shaft and so prevent noise in the driving-gears, an oil pump is directly attached to, or formed integral with, the cam shaft, and a restriction is formed in the oil-delivery pipe. As shown, the oil pump is of the gear-wheel type, and one of the rotors is integral with the cam shaft C. A valve J loaded by an adjustable spring is inserted in the delivery pipe, and the oil is led to the interior of the cam shaft or to the camshaft bearings. According to the Provisional Specification, the pump may have an intermittent delivery, the pump resistance occurring at the points where there is little or no normal resistance to the rotation of the shaft.

Title: Apparatus for use with memory means
IPC: G11C8/00
Filed: 1977-06-21
Abstract: A memory array, having a plurality of intersecting rows and columns, stores digitized speech. Each row and column intersection consists of a binary storage cell for storing one bit of digitized speech. Incoming digitized speech is loaded into columns of the memory array in a plurality of repetitive loading sequences, each loading sequence including: reading out the bits stored in successive rows of binary storage cells, replacing in each successive row of bits, a predetermined one of the bits in the read out row with a successive one of the bits of the digitized speech and writing each read out row of bits including the replaced bit back into the row. Multibit binary grunts (digitized speech segments) stored in the array are read out therefrom by applying the bits of the grunts to time slots in frames on a time-division highway, each frame being of n bits duration and including one bit from each of n grunts stored in the array. A selected grunt is extracted from the highway by commencing a count of the bits on the highway with a first bit of the selected grunt and by extracting the first bit and every nth bit thereafter. Memory malfunction is indicated when the number of rows in the array containing parity errors exceeds a predetermined threshold number.

Title: Improvements in or relating to electrolytic machining
Inventor: WILKINSON BERNARD HALL
IPC: B23H7/18
Filed: 1965-06-18
Abstract: <PICT:1036549/C6-C7/1> In a method of manufacturing an electrolytically machined workpiece in which the workpiece 10 and a cathode 13 are mounted for relative movement towards or away from each other with a gap therebetween, an electrolyte is supplied to said gap and the workpiece is maintained at a positive potential with respect to the cathode, a first signal is derived which is representative of the conductivity of the electrolyte and a second signal is derived which is independent of the electrolytic current and is representative of the rate of said relative movement between the workpiece and the cathode, the first and second signals are combined to produce a control signal which controls the relative movement between the workpiece and the cathode so as to maintain the gap there-between at a predetermined size. The first signal is derived by passing A.C. current through a conductivity cell 19 through which the electrolyte flows. The second signal is produced by a servomotor generator 25, driven by servomotor 14 which effects the movement of the cathode 13. By means of controls 29, 30 the signals are arranged to be equal when the gap is of the required value. The two signals are rectified at 23, 26 respectively and fed to the servo-control device 17. The resultant current is converted to a pulsing signal by means of chopper 27, and passed through amplifier 28 to the servo-motor 14. An arrangement of relay 32, cathode follower 34 and associated circuitory is provided which enables the cathode to be advanced or retracted independently of the servo-control device.

Abstract: 765,367. Extruding; working at specified temperatures. SCHLOEMANN AKT.-GES. Sept. 8, 1954 [Nov. 20, 1953], No. 25995/54. Drawings to Specification. Class 83 (4). In the sheathing of heat-sensitive cables or extruded rods or tubes of synthetic material, with heated metal, particularly lead or aluminium, by means of an extrusion press having a cooled die and mandrel and a cooling device, such as a sprinkler, for acting on the sheath as it leaves the die, and wherein the extrusion is stopped whilst the press container is recharged, the speed of extrusion is gradually reduced before each stop period with continuance of the cooling, in such a manner that the cable or the like is not damaged by heat but the temperature at the extrusion die is maintained sufficiently high for extrusion to be resumed. The extrusion speed is preferably 10 centimetres per second and is gradually reduced to zero in one minute. If the stop period is prolonged the coolant supply to the die and mandrel may be throttled to prevent the temperature falling below a predetermined value. Thermocouples may be provided on the mandrel and/or die for indicating the temperature and enabling the supply of coolant to be controlled automatically. An example is given of a cable of 20 millimetres diameter insulated with dry or impregnated paper, sheathed with aluminium to a thickness of one millimetre. The initial temperature of the aluminium is 530 C. and the temperature of the die and mandrel is cooled to 180 C. during recharging.

Abstract: 698,400. Discharging mechanism. SAUNDERS-ROE, Ltd. Sept. 20, 1950 [Oct. 12, 1949], No. 26218/49. Class 9(ii) Articles are carried and locked on the periphery of a drum which rotates to bring the article into a discharge position. an ejector then operating on the article which is simultaneously unlocked from the drum, the ejector then returning to its cocked position. In Fig. 1, a drum 11 mounted in a flying boat hull 10, is rotated intermittently in a clockwise direction on a shaft 12 driven by a motor 14. Buoys 19 are locked in the recesses 18 by projections 23, Fig. 7, mounted on spring-loaded plungers 20. Energizing the solenoid 35, Fig. 10, by closing the switch 40 frees a pawl 33 from a ratchet 34 mounted on the shaft 29 thus allowing the arms 30 to pivot on the shaft 29 under the action of the spring 32. The arms 30 carry plates 31 provided with cams 43 so that the plunger 20 is operated to release the buoy. After ejection of the buoy the arms 30 operate a switch 44 controlling a motor 38 which recocks the ejector mechanism. When in a recocked position the arms 30 operate switches 46 and 47 stopping the motor 38 and starting the motor 14 which rotates the drum till another buoy touches the switch 48 to stop the motor 14. The apparatus can be so wired as to allow ejection of the buoys in any chosen order.

Title: Method of Coating Substrates with Firmly Adhering Layers of Pyrocarbons
IPC: C01B31/00

Abstract: 1,168,505. Coating with carbon. SIGRI ELEKTROGRAPHIT G.m.b.H. June 9, 1967 [June 13, 1966], No. 26866/67. Heading C7F. [Also in Division C1] Smooth substrates having micro-porous surfaces are coated with a firmly adhering pyrocarbon layer by thermal dissociation of gaseous or vaporous organic compounds by contacting the organic compound with the substrate while the latter is at the temperature at which the compound dissociates to deposite carbon and initially adjusting at least one of the gas pressure and substrate-temperature magnitudes for deposition of pyrocarbon in the surface adjacent pores of the substrate and then, without removing any pyrocarbon, gradually increasing at least one of the said magnitudes until a pyrocarbon layer is deposited. The organic compound preferably consists of one or more hydrocarbons e.g. methane or propane. The process is particularly applicable to coating industrial carbon or graphite particularly those having a polished surface of less than 2 microns irregularity. Advantageously, the temperature of the substrate is adjusted initially to 1000 to 1500‹C. and then continuously increased preferably by at least 500‹C. and preferably at a rate of 1 to 20‹C. per minute. When the optimum temperature e.g. one from 1500 to 2100‹C is reached the temperature is preferably kept constant during continuance of the dissociation process until the coating of pyrocarbon has attained the desired thickness.
