Abstract: 1,051,441. Camera supports. A. E. DEAN & CO. (X-RAY APPARATUS) Ltd. June 18, 1964 [June 28, 1963, No.25797/63. Heading G2J. [Also in Division H5] An extendable guide 1 for constraining movement of, for example, an X-ray tube or camera, relative to a support, (carriage 2), comprises three arms each consisting of a series of hinged plates, the arms being connected together at alternate hinges. The embodiment described relates to a guide and support for an X-ray tube but it can equally be applied for use with an X-ray camera. The guide 1 is carried by the carriage 2 which moves along rails within a carriage 3 which itself is movable along rails suspended from the ceiling. The X-ray tube X(Fig. 1) (or camera) may be rotated in a bracket 5 about an axis perpendicular to the common axis of the guide. The bracket is bolted to the flanged head 6 Fig. 5, (not shown) of a spindle 7, which can rotate within a sleeve 8 and is locked in the required orientation by a spring- loaded plunger 30. Shackles 10, 11 couple the sleeve 8 to cables 14 which take the weight of the X-ray tube (or camera). Vertical movement of the tube (or camera) is controlled by contraction or extension of the guide 1, which is attached at one end to the carriage 2, and at the other to the sleeve 8 by common hinge pins 18, which are received by three arms 16 of the sleeve 8 and the bearing arms 20 of the three lower plates 21. Of the other plates 23 in each series the hinges nearer the common axis of the guide are fixed with respect to the corresponding hinges of other series by means of bushes 27 and rings 28, causing symmetrical contraction or extension of the guide. As the guide moves, the cables 14 are taken up or let out by a drum Fig. 4, (not shown) which is mounted on the carriage 2 which is controlled by an electric motor and gearbox. Another drum is driven from the first to control the operation of microswitches, of which upper and lower switch limits are provided for safety, as is a pressure plate on the X-ray tube (or camera) which operates a micro switch on contact with an obstruction such as the patient. Also maximum extension stops 29 are provided. An indication of the tube's (or camera's) height is provided by a tape attached to the carriage and let out from a reel mounted on the bracket 5. Twospeed control, if necessary by two motors, may be provided for speed of positioning of the tube (or camera) and further microswitches on the drum can be used for predetermined positioning.

Abstract: 1,231,908. Associative stores. INTERNATIONAL BUSINESS MACHINES CORP. 9 April, 1969, No. 18103/69. Heading G4C. An associative store comprises a plurality of input registers arranged to contain search arguments to be used in associative store accessing operations and control means arranged on every operation involving a search freely to select one or more of the input registers as the source of a search argument. In a first embodiment, either of two input registers can apply the search argument via a variable mask register to the store proper, and be used as an input/output register for a word being written or read, the mask register passing only those orders not used for the search argument during read/write. The operations are controlled by a decoder responsive to the input register contents. A second embodiment, capable of using different masks for a search than and subsequent read or write, does not use the input registers during read, the word read passing via either of two further mask registers connected respectively to buses connected to the input registers respectively. In modifications, the search argument is compiled in the (first) mask register by concatening non-overlapping fields from optionally different input registers, or by ANDing, ORing or EXCL-ORing corresponding bits from the two input registers. Another modification has two associative stores, each as above, with corresponding input registers connected to common buses, but with each input register only part of a word wide and one of the registers corresponding to a different part than the others so that characters from different words in one store can be concatenated into the same word in the other store. A plurality of associative stores may simultaneously provide respective characters of a word on a bus by suitable control of the output masking. Application of the invention to the stores of Specifications 1,186,703 and 1,127,270 is disclosed.

Abstract: 1,238,162. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 26 March, 1969, No. 15819/69. Heading G4A. In a data processing system, a data handling unit detects and counts errors in data handled thereby, the count being made available elsewhere in the system in response to a request signal. In a sytem with two processor units and two storage units, which is a modification of that of Specification 1,238,161, which is referred to, either processor unit can supply configuration data to the units to configure them into one or more subsystems, each unit then responding to signals from within the same subsystem only. On detection of an error, the error is corrected if possible, using an error-correcting code in a storage unit, and by instruction retry (up to a predetermined number), as in Specification 1,168,414, which is referred to, in a processor unit. Each unit counts its detected errors (including unsuccessful retries). If correction is not achieved as above, the processors are notified. The processors are also notified if correction is achieved, either every time (error counter non- zero) or when the error count is 16, according to two mode bits from the configuration data. The processor (assuming only one is configured to respond to the notification) interrupts its programme and reconfigures the system in response to the first sort of notification, e.g. to exclude the faulty unit. In response to the second sort of notification it interrupts its programme and requests stored error data (location of error, and optionally the error count) from the notifying unit and may respond to it by reconfiguring, or by changing the error-notification mode bits, or by continuing without change.

Abstract: 1,238,948. Reciprocating pumps. DAIMLERBENZ A.G. Sept.24, 1968, No.45311/68. Heading F1A. A reciprocating pump, such as an oil lubricating pump, has a stationery piston 22 and a moving cylinder 15 which reciprocates and rotates simultaneously to control the inlet and outlet of the pump by its rotation, the cylinder being actuated by an eccentric cam follower 18 which moves in a part cylindrical cam surface 25 thus providing reciprocation e.g. two oscillations/revolution. The worm gearing 12, 13 sets the pump cylinder 15 in rotation together with the plug 16, its collar 17 and the cam follower 18, the whole being pressed upwards by the spring 23<SP>1</SP>. The stroke of the pump can be adjusted by adjusting the screw 27 via the shaft 29 and hand lever 31, thus causing the extension 27<SP>1</SP> to project a required amount beyond the cylindrical surface 25. The travel of the screw 27 is limited by an adjusting disc (28) Fig.2 (not shown). The oil comes in through a supply line 10<SP>1</SP> and into two axial bores 33, 34, Fig.4 from which the two working chambers 40, 41 are fed via appertures 39 in the cylinder 15. As the cylinder rotates oil is discharged through the appertures 39 to the connections 38, 37 and 36, 35. In a modification Fig. 5 (not shown) two stationary pistons (46), (47) are provided resulting in three working chambers (48) (49) (50) and hence a total of six pressure connections are obtained.
