Title: Memory control for toll systems
IPC: H04M15/04
Filed: 1973-12-06
Abstract: 1441607 Data storage system INTERNATIONAL STANDARD ELECTRIC CORP 6 Dec 1973 [11 Dec 1972] 56519/73 Heading G4A [Also in Division H4] An arrangement is described for recording data relating to telephone bills in successive locations of a core memory and for transferring blocks of data recorded in the core store on to magnetic tape. Two recording systems are connected to a telephone switching network, one of the systems being active at a time and both sharing an operators display and key panel. Each time data is presented for recording a "demand" signal is generated and if the core memory is not busy (see below) a control circuit sends a signal CE which causes a fixed length clock signal to be fed to the core memory to record the data. Parity checks are mentioned. Data is read into successive locations in the core addressed by a write address register until a block of data (e.g. 512 characters) has been assembled. At this point the memory is made busy and any further demand signals produce no response. A magnetic tape unit is started, a core memory read address register is reset and, in response to clock signals supplied by the tape the block of data is written on the tape. During the transfer the parity of the data is checked, erroneous data being replaced by "Z's" until the read and write address register contents are the same. If the data contained errors the transfer process is repeated, e.g. up to four times when an alarm is activated, otherwise the write address register is reset to zero and the core memory freed to receive further data. A transfer of data in the core memory to the tape may be initiated at any time manually. If a manual transfer is initiated before a complete block has been assembled the missing data is replaced by "Z's" on the tape so as to keep the blocks of data on the tape a constant size. Arrangements are provided to supply labels for recording, together with the data from the core memory, on the tape. The labels may indicate the beginning and end of billing data for a month, date, time, &c., there being provision to transfer any data in the core to the tape at midnight so as to start a new block with an appropriate label. The Specification describes logic gating circuits for performing the required functions.

Filed: 1967-12-21
Abstract: 1,152,139. Bearings. BROWN BOVERI & CO. Ltd. 21 Dec., 1967 [23 Dec., 1966], No. 58043/67. Heading F2A. In a hydrostatic axial bearing arrangement for a shaft 1, a piston 9 and a cylinder 7 are positioned at an end 2 of the shaft and a piston 10 and a cylinder 8 are positioned at the end 3 of the shaft. Each piston is separated from the end of a shaft by means of a gap which is supplied with pressurized-fluid, and is urged towards the respective shaft-end by pressurizedfluid which is supplied to its cylinder; the amount being supplied is controlled by valve means which is operable in response to axial movement of the shaft. Thus the pressure of fluid in each cylinder is varied in order to oppose the respective axial movement of the shaft. In an embodiment the shaft 1 is provided with a groove 17 which guides a disc 19. The latter is mounted on a rotatable and axially displaceable shaft 21 which also carries valve members 23, 24 thereon. In use fluid is pumped to the valve means from a tank 29, via a pump 27 and pipes 25, a pressure-holding valve 31 being connected to the pipes 25. If the shaft is displaced to the left, for example, the member 23 allows pressurized-fluid to flow into a pressure-space 12 of the cylinder 7, via a pressure-space 33 of the control valve and a pipe 15. At the same time the member 24 allows pressurized-fluid to flow from the pressure space 13 of the cylinder 8 and into the tank 29, via a pipe 16, a pressurespace 34 of the control valve and a return-flow pipe 36. The pistons 9 and 10 are each provided with a bore 14 and with a sealing portion 11. The pressurized-fluid in the gap between each portion 11 and the respective end of the shaft acts as a connection so that the pistons are rotated by the shaft. In modifications each piston is supplied with lubrication grooves and with a throttle bore therethrough; each piston is spring-urged towards the shaft and has a concave surface which forms a gap with the respective shaft end; and each piston has a hydrodynamic axial bearing mounted therein, a resilient ring being provided between the piston and the bearing.
