Title: Power saving circuit for calculator system
IPC: G06F15/78
Filed: 1973-12-14
Abstract: 1454400 Electronic calculators TEXAS INSTRUMENTS Inc 14 Dec 1973 [11 June 1973] 58040/73 Heading G4A In a calculator, a matrix decoder 708, Fig. 4f, has transistors selectively coupling column input lines to row output lines A and has an associated switching circuit 800 which receives a periodic gating signal to decouple power from the decoder to avoid unnecessary power consumption. As described, the decoder 708 forms part of the input selector 703, Fig. 2 of a sequentially accessed semi-conductor storage array 700 which comprises 10 registers each of 16 BCD digits. When a flag A signal is "on" signifying an address word, 3 BCD digits applied sequentially to the I/O terminals specify the operation to be performed, a particular register in array 700, and a chip address for comparison with a wired in address at 717 where more than one 10-register chip array 700 is provided. The operation specified may be input, output or clear, the latter being indicated by a pair of bits which specify a particular register to be cleared, all registers in one chip to be cleared, or all chips 700 to be cleared. A register address digit is gated to input or output register select circuit 708 or 709 depending on the operation, and is decoded to select the appropriate register in array 700. Input and recirculation operations performed in array 700 do not require output of data from the array and for these operations power is not gated to the output selector 709.

Title: Improvements in or relating to grinding machines
IPC: B23Q15/00
Filed: 1967-12-27
Abstract: 1,209,059. Grinding. LANDIS TOOL CO. 27 Dec., 1967 [27 Dec., 1966], No. 58703/67. Heading B3D. In a grinding machine for repetitive work in which the grinding-wheel 13 is fed to a positive stop, the feed mechanism is incrementally adjusted in response to a signal from a gauge 26 to correct for variations in work size before the next grinding operation. The feed-screw 28 is advanced rapidly by a piston 29 and then slowly by a rack-and-pinion 38 until a pin 83 on the slow feed shaft 36 engages a stop 84, the operating fluid being controlled by a solenoid 3, an infeed valve 54 and a slow feed valve (not shown). Switches 7LS, 8LS on the slow feed mechanism initiate the advance of the gauge 26 to the workpiece W and sparkout. If the workpiece is found to be oversize or approaching undersize, as indicated by the gauge dial, Fig. 5 (not shown), the appropriate signal is given to the controlling solenoids SOL-7, SOL-9 of a pawl-and-ratchet mechanism 45 to advance or retract the feed-screw 28 by one increment. When it is necessary to retract incrementally, this is done when the grinding wheel reaches its back position; incremental advancement is also effected at this back position when the circuitry is modified as in Fig. 2A (not shown).

Title: Process for the recrystallization of a base material under a  clad layer
IPC: C21D9/50
Filed: 1972-12-29
Abstract: 1413129 Heat treatment of metals DE ROTTERDAMSCHE DROOGDOKMAATSCHAPPIJ BV 29 Dec 1972 [30 Dec 1971] 60130/72 Heading C7N [Also in Division B3] The coarse-grained region of base material immediately underlying a weld-deposited cladding is recrystallized to a fine-grained structure by applying arc heat to the surface of the cladding under such conditions that the temperature zone in which a coarse-grained structure can reform does not extend beyond the fusion line between cladding and base metal. The base metal may be pre-heated to 100‹-250‹C and the coarse-grained zone should be heated into the temperature range 725-1100‹C for not more than 1 minute. Heating is by argon arc welding torch, plasma torch or gas welding torch, the torch preferably following a zig-zag path over the clad surface to form overlapping beads. Advantageously the torch is included at 20-40‹C to the vertical. As particularly described base metal 17 underlying cladding 12 is recrystallized by locally remelting the surface of the latter by plasma e.g. of 75% helium 25% argon the torch being reciprocated over the surface. Line 16 denotes the Ac 1  isotherm.

Title: Metering system for dispensing beer or other potable carbonate liquids
IPC: G01F11/04
Filed: 1979-07-02
Abstract: A beer dispensing system comprises a pump having an outlet connected through piping 1, 2, 3, 18, 19 and solenoid valves 4, 5 to a metering cylinder 20 having a piston 21. An electronic controller 22 controls the valves 4, 5 and a shut-off valve 14 in beer outlet piping 8, 9, 12. The controller is operated by a push button switch 32 and by a flow switch 11 in the outlet piping. When the switch 32 is operated the controller 22 sets the valves to cause the pump to dispense a measured quantity of beer through the metering cylinder 20 in which the piston 21 makes one full stroke. The shut-off valve 14 is then closed by the controller and the valves 4, 5 are reset by the controller 22 to cause the piston 21 to make a small return movement. This ensures that the beer in the outlet piping 8, 9, 12 is kept under pressure and fob is prevented from forming in it. <IMAGE>
