Title: Improvements relating to Data Processing Systems
Inventor: ECCLES EDWARD STUART
IPC: G06F15/16
Filed: 1965-05-12
Abstract: 1,157,083. Fault detection system. ROLLS ROYCE Ltd. 12 Aug., 1966 [12 May, 1965 (3); 14 May, 1965], Nos. 20100/65, 20101/65, 20102/65 and 20514/65. Heading G4H. A data processing system comprises at least one plant having data outputs, at least two digital computers for processing data from the plant outputs, and means for connecting the computers in cyclic order to the plant or each plant to receive the data for the purpose of processing. In a fault-finding system (Fig. 1) for two operating plants, e.g. gas turbine jet engines E1, E2, the engines are connected in cyclic order to at least two computers C1, C2 so that in one control cycle computers C1, C2 control engines E1, E2 respectively, while in the next cycle they control E2, E1 respectively. Signals 0-7 representing fuel flow, speed, jet pipe temperature and pilot's throttle setting are fed to an input multiplexer whence they are allocated to the correct computer which processes the information and produces an output control signal which is applied to output multiplexer 12 for allocation to the correct engine. Where input signals are in analogue form, an analogueto-digital converter (not shown) may be provided. If the output of any computer is not within prescribed limits a fault finding routine is initiated. This may take the form of a programme built into each computer or alternatively a separate logic circuit (Fig. 3, not shown) may be provided. At each incorrect output an error signal is applied to registers corresponding to the appropriate engine-computer pair and since the latter are interchanged, the particular engine or computer at fault will be indicated after a number of control cycles, by the unit having the greatest number of errors. If the error is produced by a computer, that computer is disconnected, but if the error is produced by an engine, a further check is made on the outputs of the transducers producing the signals 0-3 or 4-7. A check on the engines may also be made during each control cycle since in normal operation the four parameters for each engine should increase or decrease together. This check may again be in the form of a computer programme or further logic circuitry (Fig. 5, not shown). Each parameter output is compared with its previous value and the resulting charge compared with that of the other three parameters, the incorrect change of any one parameter indicating a particular fault in the engine corresponding to that parameter output. In each fault-check logic circuit registers are provided to accumulate only persistent errors. the registers being periodically reset so that errors other than persistent ones, are ignored.

Title: Method of producing composite yarns
IPC: D02G3/22
Filed: 1973-05-02
Abstract: 1434243 Spinning composite, crimped yarns TOYO BOSEKI KK 2 May 1973 20768/73 Headings D1F and D1W A method of producing a composite yarn comprises opening a crimped synthetic thermoplastic multifilament yarn substantially non- twisted and having a torque in one direction, combining it with a staple fibre material while in the opened state, and twisting the combined yarn in a direction to cancel the torque of the crimped yarn (i.e. in the same direction as the torque direction). The composite yarn may be wound into a package and/or twist-set. The composite yarn with or without twist-setting may be knitted into a knitted structure Which is thereafter heat-treated in a relaxed state. The crimped yarn may be obtained by twisting- heat setting-untwisting, 'false twisting or modified false-twisting processes. The opening of the crimped yarn is preferably achieved by voltage application but may be achieved by stretching and relaxing the yarn. Apparatus for carrying out the method preferably comprises a pair of electrodes, e.g. needle-type electrode 1 and funnel-type electrode 2, means e.g. voltage source 3, for applying a voltage across the electrodes, means for feeding a staple fibre material e.g. drafting rollers 5, and means for combining and twisting the crimped yarn A and staple fibre material B, e.g. ring spinning device 6. The twist of the composite yarn preferably has a twist constant between 45 and 110 on the metric system. The crimped yarn A preferably comprises poylester, nylon, polyacrylic or polypropylene filaments. The staple fibre material B e.g. a roving or sliver, comprises wool, cotton, flax, polyacrylic, polynosic, acetate, nylon, polyester, polyvinyl or polypropylene fibres or mixtures thereof. Knitted structures formed of the composite yarn exhibit substantially no skew tendency.

Title: Production of zirconium tetrachloride
IPC: C01G25/04
Filed: 1956-07-05
Abstract: Zircon sands, containing mainly zirconium silicate, are treated with a gaseous mixture of chlorine and sulphur, or a vaporized chloride of sulphur alone or in admixture with chlorine gas, to produce a crude zirconium tetrachloride and silicon tetrachloride which can be separated by distillation.  The reaction temperature is generally between 700 DEG  and 1200 DEG  C.  The zircon sands may be given a pretreatment to render them more easily reactive with the sulphur/chlorine reactant by: (1) fritting the zircon sand with soda ash preferably at 900 DEG  C. to form sodium zirconium silicate (Na2ZrSiO5); (2) fritting the zircon sand with soda ash and extracting with dilute acid solution, preferably H2SO4 to remove the Na2O; (3) reacting the zircon sand with caustic soda at about 600 DEG to form sodium zirconium silicate which then may be reacted with the vaporized sulphur chlorine reactant; (4) extracting the caustic soda zircon reaction product of (2) with dilute acid to remove the soda before reaction with the vaporized sulphur/chlorine reactant.  The crude condensed zirconium tetrachloride produced by the initial reaction and distillation can be purified by distilling off the impurities in an atmosphere of chlorine and then subliming the zirconium tetrachloride in a chlorine atmosphere.

Title: Improved method and apparatus for air-conditioning clothing garments
IPC: A62B17/00
Filed: 1964-05-20
Abstract: 1,063,624. Heating and cooling garments. SOC. ANON DES USINES CHAUSSON. May 20, 1964 [June 5, 1963], No. 20909/64. Heading A3V. A method of air conditioning clothing comprises circulating a stream of compressed air in a vortex chamber having a cold air outlet and a hot air outlet, the outlets being alternatively connectable to the inside of a garment. As shown, compressed air passes through a pipe 17 and a heat exchanger coil 16 wound around an ice tank 15 to a vortex chamber 3, a cold air outlet 4 leading to pipes 6 within a protective suit 1 and a hot air outlet 9 leading to atmosphere. The outlets 4, 9 have silencers 5 and 10 respectively and a needle valve 11 is adjustable to vary the temperature of the cold air supplied to the suit which includes non return exhaust valves at 8. The pipe 17 may be pre-cooled by the flow of melted ice from the tank 15 through a sheath 18 surrounding the pipe. Alternatively the pipe may be lagged with strip material constantly soaked with melted ice. If it is desired to supply hot air to the garment interior a branch circuit which by-passes the heat exchanger is used. In an alternative embodiment (not shown) the compressed air bottle is located within the housing 2. In a further embodiment the heat exchanger comprises a duct leading from a bottle of liquefied refrigerant within the housing, the air inlet pipe 17 being coiled around the duct which discharges the vaporized refrigerant to atmosphere.
Patent GB-633965-A (GB)
Title: Improvements in or relating to liquid pressure systems
IPC: B64C25/44
Filed: 1947-08-01
Abstract: 633,965. Fluid-pressure brakes. DUNLOP RUBBER CO., Ltd., and BUTLER, H. J. Aug. 1, 1947, No. 20912. [Class 103 (i)] A device for insertion in liquid-pressure systems, particularly hydraulic brake systems for aircraft, divides the system into primary and secondary parts, whereby the danger of the friction surfaces becoming useless by splashing with braking fluid from a leaking leather or gland is minimized. The device comprises exactly similar pistons 8 acting in cylinders 2 spaced apart in the same casing 1 and having between them similar operating chambers 13 and a common liquid reservoir 3. The liquid above the pistons 8, as shown in Fig. 1, is part of a primary system supplied with pressure from the main master cylinder through inlets 14, past the spring-loaded valves 18 and through passages 22. The spaces below the pistons 8 form part of a secondary system and are connected by outlets 5 to different brake actuators on the same wheel. In operation, when the main master cylinder is actuated to apply the brakes, and pressure is supplied through inlets 14, the plungers 15, which are under the action of springs 16, which are weaker than the springs 19 holding closed the valves 18, are moved downwards. They thereby force liquid in the spaces below them, which are in communication by passages 17 with the reservoir 3, through passages 16 into the annular grooves 12 just below the pistons 8, thus ensuring that any small leakage from the secondary system due, say, to evaporation, is made up. Later, when the valves 18 are lifted, liquid-pressure is applied above the pistons 8 and when once the pistons have moved sufficiently to seal off the grooves 12, the two systems are effectively isolated and the maximum amount of liquid that can leak on to the braking surfaces is that below the pistons 8. If considerable leakage does take place so that either of the pistons 8 does not move back beyond the groove 12 when the primary brake pressure is released, there will be no make-up of liquid from the reservoir 3 to the associated cylinder, which then becomes inoperative.

Title: Improved machines for making crumpets, muffins, drop-scones, pancakes and the like
IPC: A21B3/16
Filed: 1953-07-28
Abstract: 729,275. Baking-apparatus. JERSEY, D. C. DE. July 28, 1953, No. 20929/53. Class 28 (1). A machine for making crumpets, muffins, scones, pan-cakes or the like, comprises mould rings 1 fitted on an endless conveyer 2, driven intermittently to carry the rings under dough feeding means and through a cooking zone, and hot plates 4 fitted on another endless conveyer 5 driven synchronously beneath said rings during filling and cooking operations. The conveyers 2, 5 are driven intermittently through sprockets 3, 6 by a geneva star mechanism and greasing, filling, browning and separating the crumpets from the hot plates take place when the conveyers are stationary. The rings are greased by a felt pad 8, fed with oil from a reservoir 14, the pad 8 being raised and lowered by a linkage and rotated by a belt drive, Fig. 3. After greasing the rings are carried round until they engage the hot plates 4 when they are filled with dough from a hopper 9. Beneath each hopper is a casing forming a chamber 21 and containing a plunger 22 and a valve 27. Dough is drawn from the hopper 9 into chambers 21 by plungers 22 through ports 28A, 28 in the hopper 9 and valves 27 respectively. Valves 27 are then turned so that ports 29, 29A, in the valve 27 and casing respectively, coincide and the dough is expelled by plungers 22 and falls into the'rings 1 underneath. The filled rings 1 then pass through the cooking zone where burners 10 heat the hot plates. At the end of the cooking zone the rings pass beneath a reciprocating gas heated browning plate 11. After cooking, the conveyers separate and the crumpets remain on the hot plates from which they are stripped when the latter become vertical by blades 41. Synchronous action of all the parts is achieved by linkages connected with the main drive. Electricity may be used instead of gas for heating.

Title: Improvements in or relating to gear grinding machines
IPC: B23F23/12
Filed: 1928-07-19
Abstract: 311,597. Moss Gear Co., Ltd., and Gregory, E. July 19, 1928. Turning.-The grinding-wheels employed in the production of worm gearing are prepared or trued by means of a device comprising oscillating diamond tools for trimming the sides of the wheel and a separate tool for operating upon the peripheral edge. A stud 6 is screwed at 6a into the frame of the machine and carries a split sleeve 7<a> secured' by a screw 7f and having a depending bracket portion 7 which straddles the grinding wheel 8. Extensions on the bracket are fitted with plates 7<h> adapted to bear on fixed projections on the machine frame. Each leg of the bracket 7 is bored to receive the trunnion 15a of a casing 15 which accommodates aT-shaped sleeve 12. The horizontal portion of this sleeve carries the sliding holder 11 of the diamond tool 9, adjustment being effected from a micrometer head 13. The upper end of the sleeve carries a screw cap 16 which may be locked by a plunger 17 and screw 16<a>. The stud 6 also carries a sleeve 20<b> adjustable by a screw 7<g> and having a depending portion 20. This sleeve carries a loose sleeve 22a on the upper end of a holder 22 carrying a diamond 23 for trimming the periphery of the wheel. For the preliminary trimming of the side faces, the wheel is rotated and the casing 15 is swung about the trunnion 15a. The side face is then radiused by swinging the casing into engagement with a stop 7<k>, releasing the cap 16, and rotating the sleeve 12 about its axis, the diamond thus moving in an arcuate path in a plane containing the grinding wheel axis.

Title: Device for automatic operation of washing machines
IPC: D06F34/30
Filed: 1963-05-24
Abstract: A timing control, Figs. 1 and 2 (not shown) for the automatic operation of washing machines is of the kind wherein a cycle is divided into basic steps such as prewashing, washing, rinsing, and spinning, the steps being controlled by a rotatable selector Sel which switches on and off the various operating circuits.  The control comprises also a relay M stepping-on the selector under the action of electric pulses of regular but adjustable frequency.  A pulse generator T generates these pulses.  The control further comprises a number of preselector circuits corresponding to the number of basic steps and connected to the pulse generator.  Each preselector circuit has means whereby the frequency of the pulses can be regulated within a wide range, from a maximum corresponding to a quick advance of the selector so that the corresponding step is effectively omitted, and a minimum corresponding to a desired maximum duration of the step.  Cams CK rotated with the selector, actuate switches to connect the preselector circuits in succession with the pulse generator as the steps are gone through.  The pulse generator circuit includes two transistors T1, T2 connected with a condenser C4 and resistors R8, R3, R5, R6, R2, this circuit being fed by a transformer TA through rectifiers D1, D2.  Four circuits corresponding to the four basic steps are connectible through push buttons P, L, R, C with the pulse generator.  These circuits include, for the actual steps, variable potentiometers Ph1, Ph2, Ph3, Ph4, whereby the frequency of the pulses is adjustable, and in series with resistors R1.  The potentiometers, or alternatively paralleled resistors R7 corresponding to a fixed frequency for subsidiary water-discharge steps, are brough into circuit by four switches K1, K2, K3, K4 actuated by the cams CK.  The push buttons P, L, R, C activate each a series of four switches shown in banks X, Y, Z, and W.  Buttons P and R have been operated so that the corresponding steps are omitted.  Actuation of two switches K11 and K21 in a bank K1 under the control of additional cams CKL on the selector, cause energization or de-energization of a relay Rel 1 controlling the operating circuits.  In the case of the rapid rotation of the selector corresponding to a step to be omitted, the contacts of the appropriate switch in the bank W will upon the contacts in the switch bank K1 being brought into the position ab by the cams CK1, complete a circuit whereby a relay Rel 2 is operated and its associated contacts, through which power is supplied to the other parts of the machine, to be opened so that power is supplied only to the generator and its associated circuitry.  Where a step is not to be omitted the contacts of bank W are in such position that relay Rel 2 is not operated.  The selector is moved initially from the "off" position by operation of the "start" button, Fig. 2.
