Patent GB-442430-A (GB)
Title: Apparatus for delivering change
IPC: G07D1/00
Filed: 1934-07-02
Abstract: 442,430. Money-delivering apparatus. GEE, G., 80, The Grange Drive, Winchmore Hill, London. July 2, 1934, No. 19507. [Class 27] Coins to be delivered as change are stored in a number of parallel magazines a, each associated with a spring-retracted pivoted plate h for supporting the coins, and a depressible ejection plunger n. Initial movement of a plunger causes its lower tapered end to enter partially overlapping holes g, g<1> in the ends of a flexible clamping ring d surrounding the lower end of the tube, thereby contracting the ring B so as to constrict the lower slotted end of the tube to grip the lowermost coins therein. Subsequent movement of the plunger causes it to engage and tilt the plate h to discharge the coin or coins resting thereon and beneath the mouth of the tube. The Provisional Specification describes a modified construction in which the clamping ring itself tends normally to constrict the lower end of the tube, but is operated on by a wedge-shaped part of the plunger when unoperated to relax its pressure and free the coins.

Title: Apparatus for controlling the addition of supplementary air to the exhaust gas of internal combustion engines
IPC: F01N3/22
Filed: 1975-05-09
Abstract: 1513924 Automatic control of engine exhaust ROBERT BOSCH GmbH 9 May 1975 [11 May 1974] 19546/75 Heading G3R [Also in Divisions B1 and F2]  Supplementary air added to the exhaust 15 of an I.C. engine 10 having after-burner device 16 is controlled in response to the output of an oxygen sensor 40 which acts through a "threshold value" switch 38. The supplementary air supply is also dependent on engine speed and, in some conditions, induction manifold pressure. A "safety circuit" ensures maximum air during warm up and/or the failure of the sensor voltage. The air is supplied by an engine driven fan 13 via a valve 14. This is held open at 30, 31 by a spring 37 when inlet pressure is applied to the top (via 22) and to the bottom (via flap valve 23 and conduit 24) of a diaphragm 36, and this occurs when solenoid 41 controlling flap 42 is energized. If the oxygen sensor output voltage, which changes abruptly at stochiometric air/fuel ratio, exceeds a threshold (too much oxygen) a transistor switching circuit 38, Fig. 2 (not shown), de-energizes 41 so that flap 42 connects the bottom side of the diaphragm 36 to engine exhaust, via 26. Thus, the supplementary air now depends upon the pressure differential of inlet and exhaust, and may be cut off completely. In normal operation, 41 is switched continually; if it does not (e.g. during warm up or failure) for a time determined by a capacitor timing circuit in 38 the transistor circuit is automatically switched to the energized state, to ensure maximum supplementary air.

Title: Multipelex telecommunications systems
IPC: H04J11/00

Abstract: 1378753 Multiplex transmission DEFENCE SECRETARY OF STATE FOR 17 May 1972 [9 June 1971 24 Sept 1971] 19657/71 and 44637/71 Headings H4R and H4P In a Boolean function multiplex transmission system binary information from a plurality of sources is used to modulate corresponding binary code words, the modulated code words being combined in a majority circuit, transmitted and separated by correlation using majority logic. The invention is restricted to the use of specific 7 bit codes which are truncated Walsh functions. To each code is added a synchronization bit. As shown the codes are repeatedly generated at respective outputs W1 to W7 of a generator, modulated by corresponding binary sources C1 to C7 in modulo two adders 2, and combined into a single pulse stream in a majority gate 5. The resultant codes have a synchronizing bit added at 6 and a shift register arrangement 7 delays alternative bits by eight bits before transmission over path 8. At the receiver the synchronization bit is extracted at 9 and a further shift arrangement 10 delays the remaining undelayed bits by eight bits such that all bit s have been delayed by the same amount. The delayed codes are fed to a shift register 11 and majority gates 12/1 to 12/7 each wired to the "0" and "1" outputs of the stages of the register 11 in accordance with the particular code they are intended to detect, and arranged to reproduce to synchronization flip-flops 13/1 to 13/7 the signals at C1 to C7. The delays are introduced to reduce the risk that adjacent bits in the resultant codes are received erroneously due to transmission noise. While less than the maximum number of channels are in use it is possible to correct errors at the receiver. Alternative codes with + 1 and - 1 elements may be used if multiplication rather than logical addition is employed.

Title: Improvements in or relating to a process for producing water gas
IPC: C10J3/00
Filed: 1954-07-06
Abstract: 747,461. Gasifying solid carbonaceous materials. PITTSBURGH CONSOLIDATION COAL CO. July 6, 1954 [July 20, 1953], No. 19737/54. Addition to 673,170. Classes 55(1) and 55(2). The process according to the parent Specification of generating water gas by passing steam into a mixture of carbonaceous fuel and lime is operated in continuous manner and the materials are kept in a fluidized state ; the reaction temperature and pressure are maintained at 1500‹ -1750‹F. and 15-50 atmospheres respectively and the partial pressure of the steam is kept below 13 atmospheres throughout the entire reaction zone. A bed of lime on a porous plate 12 is first heated to reaction temperature by external heating or by burning producer gas or powdered coal within the vessel itself. Finely divided char is then fed from a hopper 14 and steam from a line 18 is mixed with recycled gas through a line 19 in such proportion that its partial pressure is below 13 atmospheres and admitted below plate 12 at fluidizing velocity. Additional steam may be introduced into the bed interior through a perforated pipe 21. Product gas passes through a separator 23 to an offtake 26 to which the recycle line 19 is connected. Carbonate formed is continuously withdrawn through a conduit 30 and carried by an air stream to a regenerator 34 heat being supplied by combustion of the residual carbon or of introduced gas or by injecting flue gas. The hot regenerated lime returns to the generator through a conduit 44 and supplies some of the heat required for the steam-carbon reaction beyond that provided by the absorption of the carbon dioxide produced. Any additional heat may be obtained by external heating or feeding in small amounts of oxygen. The product gas may comprise hydrogen 50-75, methane 10-30, carbon monoxide 1-15 and carbon dioxide 1-8 per cent.

Filed: 1926-08-11
Abstract: 267,793. Marks, E. C. R., (Williams Oil- O-Matic Heating Corporation). Aug. 11, 1926. Electrically controlling fires and air suppliers. -An electric motor operating pumps to supply an atomized fuel mixture to a. burner is controlled by a series of switches and a thermostatic switch T, ignition means being also provided. The switch T is supported by means of a clamp on the fuel tube 17 against the discharge opening and near the combustion chamber, and is in circuit with a time-switch S. The thermal switch in normal operation, on attaining a certain temperature, acts to cut out the time switch but if the ignition fails and the fuel is unignited, the switch does not cut out the time-switch and the latter accordingly after a limited time cuts off the operation of the burner.

Title: Improvements in and relating to a method of lining pipes
Inventor: SAVILLE FRANK
IPC: B29C49/26
Filed: 1960-06-07
Abstract: 932,910. Turning inside out. DUNLOP RUBBER CO. Ltd. May 25, 1961 [June 7, 1960], No. 19855/60. Class 112. [Also in Group XXVIII] In a method of lining a substantially rigid pipe 1, e.g. steel, copper, lead or glass fibre reinforced synthetic resin, an end 7 of a plastic lining, e.g. of natural or synthetic rubber or synthetic resin, is attached to one end of the pipe, the lining extending outwardly of the pipe and fitting around a closed mandrel 5 located in position to traverse the pipe, the other end 9 of the lining being attached to the mandrel, and creating a difference in pressure between the interior of the pipe and the exterior space occupied by the mandrel whereby the lining is progressively rolled off the mandrel and attached to the internal surface of the pipe by means of an adhesive layer. As shown, the mandrel which is supported on rollers 25 is a tube of aluminium or steel, closed at one end 6, or alternatively, is closed at both ends or is an inflatable bag, and the pipe 1 is secured to a metal pipe 11 closed by a plate 19 having a vacuum pump connection 21. Reduction of the air pressure within the pipe 1 causes the mandrel to move into the pipe so that the lining is progressively rolled off the mandrel, turned inside out and attached to the interior surface 24 of the pipe, that surface and the inner surface of the liner having previously been coated with a natural or synthetic rubber pressure adhesive. The end of the lining is flared radially outwardly and secured to the flange 3 of the pipe, and the lined pipe is then placed in a steam autoclave until the lining is vulcanized. A cable attached to the mandrel and wound about a braked capstan controls the rate of movement of the mandrel into the pipe. In alternative methods, the mandrel is allowed to move into the pipe a short distance at a time, and is pulled back axially-outwardly relative to the lining and pipe by momentarily releasing the vacuum and sealing of the lining on the mandrel, or the pressure difference between the interior of the pipe and the mandrel is brought about by applying a positive air pressure to the mandrel with respect to the interior of the pipe.

Abstract: 892,217. Forging. BRITISH IRON & STEEL RESEARCH ASSOCIATION. June 10, 1960 [June 11, 1959], No. 20021/59. Class 83 (4). A press for forging elongated workpieces 14 has means 24 for sensing the axial position of the workpiece. The latter is gripped by a manipulator 15, 16 of the kind described in Specification 874,909 controlled as described in Specification 892,216, and is moved progressively between the press tools 12, 13 so as to forge the portion 17, 18. The press is controlled as described in Specification 874,908. To gauge the distance 17, 18 accurately without marking the workpiece, the latter is engaged by a telescopic sensing head 24 carried by a plunger 20 biased by hydraulic or pneumatic pressure. The plunger is connected by rack-and-pinion gearing or by a cable 25 to a potentiometer 23 to produce a varying voltage corresponding to the distance B. This is compared with a constant but adjustable voltage and the voltage difference is shown on a meter which indicates zero when the position 18 is reached. Alternatively, the voltage difference may control the press so that forging ends at position 18.

[Class 38 (iv)] [Also in Group XX] In a vibrating wire magnetic compass, as described in Specification 600,165, [Group XXXVIII], the wire tends to vibrate in a " preferred plane," the position of which is determined by manufacturing irregularities ; in the present invention, the support for the wire and its preferred plane of vibration are maintained fixed in space automatically. As shown, Fig. 2, the vertical wire 11 is supported in an evacuated vessel 17 in the plastic shell 45 and is energized by A.C. from amplifier 63 so as to vibrate in the earth's field. The outputs from the capacitative pick-offs 19, 21 are amplified at 31, 33 and then applied through inductive device 61 to the phase-sensitive amplifier 35 to energize the motor 37 which positions the drum 45 and so maintains the wire 11 fixed in space against turning in azimuth of the craft. The windings of 61 are manually displaceable to permit of the adjustment of the input to amplifier 35 to zero when the wire 11 is vibrating on its preferred plane. Specifications 601,051 and 610,530, [both in Group XX], also are referred to.
