Patent GB-1037070-A (GB)
IPC: G09B29/00
Abstract: 1,037,070. Coin-box telephone systems. SODECO SOC. DES COMPTEURS DE GENEVE. Sept. 16, 1963 [April 25, 1963], No. 36311/63. Heading H4K. A device for signalling to the exchange the amount inserted into a telephone coin box comprises a device for registering the amounts put into the coin-box, and an impulse transmitter arranged simultaneously to count down the registering device and to cause A.C. impulses to be reverted to the exchange. Upon request by the exchange operator the necessary coins are inserted, which after passing a verifier for checking weight and size, reach a device indicating the value of each coin which is sent to a counting chain which stores value of the total amount. The coins are meantime held in a compartment from which they can be released to a refund exit, should the subscriber hang up at this stage. An impulse generator is then started, each impulse enabling an oscillator to send a burst of A.C. back to the exchange and also to reduce the count of the stored value by one. Impulsing stops when the count reaches zero. The impulses having been counted at the exchange the operator sends a signal which opens an exit from the coin compartment towards the cash box which is reached via a further coin evaluation device which causes the value of the coins to be stored. This value is fed to the counting chain which is again counted down by the impulse generator which, this time, also pulses a further counter to register the amount let into the cash box. The coins may be passed to the cash box individually by signals from the exchange, these signals operating via a delay device a circuit breaker for shutting down the connection. The circuit breaker, however, is disabled by the passage of the coin through a verifier on its way to the cash box so that the connection is not shut down until no more coins are present for collection.
Patent GB-1037190-A (GB)
Abstract: 1,037,190. Ticket-validating apparatus; statistical apparatus. W. BOLLMAN, E. BOLLMANN, and J. A. BOLLMAN. Nov. 1, 1963 [June 27, 1963], No. 43313/63. Headings G4M and G4T. A machine reads the value from an inserted ticket recorded in the form of notches in its edge, passes this value to adding and data storage means and prints a receipt on the ticket. The ticket (Fig. 1, not shown) has its price and the journey for which it is valid edge punched at 13, 14 in binary-coded decimal fashion, and has a corner 15 detached to enable the machine to check that the entered ticket is correctly orientated. The ticket inserted in a slot 16 (Fig. 2, not shown) projects past feelers 19, 20 which block its entry if it is not correctly orientated, and engages a switch to start the drive of a roller 18 which draws the ticket towards the sensing position. When it can no longer be withdrawn by the operator it closes a switch 29 so that a cam drum 40 rotates. A groove in the drum surface cams a pin 42 on a slider 41 so that a pawl 44 is raised behind the ticket and a door 47 is closed over the entry slot. In the sensing position, sets of rockers 51, 52 (Fig. 4, not shown) positioned along opposite edges of the ticket 12 are freed so that they pivot under gravity to positions corresponding to whether the corresponding notches are present or absent. The rockers are then forced to assume one or other of the two positions by spring- pressed pawls 77 having wedges 75, 76 positioned to engage one of two slots in each rocker. Tipping members 80 are raised to sense the settings of the rockers and these settings are conveyed via rods 81, 82, 87 to a punch 83 and to a cash register 89. The rods 82 position sliders 85 below automatic keys which are spring biased downwardly but which are held in an uppermost position until the sliders 85 have been set and then selectively allowed to fall according to the setting of the sliders when released. The punch records the data on paper tape. Before ejection, the date is impressed on the ticket by manually set cam-operated impression discs 142 and a validity marking is also embossed on it. Manual keys are provided for inserting information relating to tickets the edge punch equivalents of which are not available.
Patent GB-1050052-A (GB)
IPC: G06F3/06
Abstract: 1,050,052. Electric digital data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 1, 1965 [March 25, 1964], No. 8605/65. Heading G4C. In a data filing system for storing records on a magnetizable surface, at least one field in a given record contains indicia designating the length of one other field, said indicia being used to control the length of a gap written on the surface. Each filed record, after an address marker section indicating its beginning, comprises a count field, a key field and a message field. Each of these three fields is preceded by a gap zone and followed by a verification zone, and the record as a whole is followed by a further gap zone. Each record, apart from its address marker section, and gap and verification zones, is initially stored in a computer's core memory and is then transferred to a magnetic disc or drum or tape-loop file with insertion of the remaining portions, the invention enabling variable-length records to be filed without unused storage space. The count field specifies the track address, the number of the record on the track, and the lengths of the key and message fields. The message field contains a message and the key field a code number (e.g. a part number) for identifying it. The gap zone contains timing signals for subsequent synchronisation purposes (or may be blank, or contain a unique combination of signals) from an oscillator controlling the core to file transfer, and the verification zone contains bits from a cyclic check shift register which, subsequently during read-out from the file, are compared with what they ought to be. During transfer, a decrementing counter is preset for each zone of the record and counted down. At count zero, the shift register is reset and a zone ring is advanced one step, and for each complete cycle of the zone ring a field ring is advanced one step. -One complete cycle of the field ring is used for each record and cycle end results in a request for the next record to be stored. For fixed length zones, the decrementing counter is preset by the rings, through gating. For variable length zones it is preset with fixed percentages of the lengths of the key and/or message fields specified by the count field (see above). The final gap zone following a record may be built up of several portions, variable length and fixed. Parallel to serial conversion is effected during the core-tofile transfer, under control of a bit counter. A given record on the file can be accessed by an associative search on the record number portion of the count field or on the key field after selecting the track by conventional addressing techniques. As a modification, a given record may be recorded in parallel on the file.

Abstract: 1,228,262. Pipe joints. T. D. WILLIAMSON Inc. 30 June, 1969 [1 April, 1969], No. 33035/69. Heading F2G. A pipe joint comprises a tubular housing 16, gripping means 34, 36 engaging respectively on pipes 12, 14 to be joined, the housing being formed with two pairs of annular grooves 18, 20, and 22, 24, each groove having a sealing ring. Grooves 18, 24 house the gripping means and have camming surfaces 18a and 24a respectively. The space between the sealing rings of each pair is injected with a pressurized fluid, e.g. grease, through nipples 42, 44, which may each have a back pressure valve, so that the inner rings 28, 30 move towards each other against annular stopping surfaces, sealing the pipe ends against the housing. Sealing rings 26, 32 move axially away from each other forcing the gripping means to move along the respective camming surfaces and causing them to grip the pipes radially. As shown, the gripping means have a taper to match that in the housing and are resilient split rings of spring steel with teeth on their inner diameters. The rings are temporarily held enlarged by plugs 38, 40 engaging at the split ends thereof when the housing is being slid into position, after which the plugs are removed. The internal diameter of each unsplit ring may be equal to or slightly less than that of the pipe it engages. Backing rings 46, 48 may be provided to prevent damage to the sealing rings at the split region of the gripping rings 34, 36. Joints of the invention are suitable for temporarily servicing pipelines carrying inflammable fluids, or for the repair of leaking pipelines where welding could be dangerous with the pipes full or with a leaking inflammable fluid. The housing of the joint can be welded to the pipeline after a lapse of time, when the openings of the plugs and nipples are also closed by welding. slot in the nut outer surface, covered by a sleeve 13.
