Granted: 1966-10-14
Abstract: 1,149,952. Cash registers; calculating machines. ANKER-WERKE A.G. 17 April, 1966 [3 May, 1965], No. 7003/66. Headings G4B and G4T. A cash register or calculating machine includes a record strip 5 and a separable voucher strip 6 superimposed at a printing station A for simultaneous printing on both strips, a feeding device controlled by manually operable keys in the cash register or calculating machine for feeding the record strip firstly in a reverse direction and then a forward direction during each entry and totalling cycle to advance the record strip by one step overall during each cycle and feeding the voucher strip by one step during an entry cycle and a plurality of steps during a totalling cycle, and a printing block 15 in rolling contact with the voucher strip during a totalling cycle to print fixed information on the voucher strip. During each machine cycle, a main drive shaft 26 is driven through one revolution to oscillate a gear segment 31 driving a toothed segment 32. A pawl 39 on the segment 32 engages a ratchet 42 fast with shaft 4 to rotate feed roller 3. The pawl 39 is maintained in engagement with ratchet 38 during counterclockwise movement by engagement of a pin 39a on the pawl with an edge of a slot 1a in a side wall until the pin enters the enlarged area 1d to release the ratchet for one step. Thus the record strip is moved counterclockwise by the roller 3 through six steps to position the last line of print above the print station. During clockwise movement of the segment 31, the pawl 39 engages the ratchet 38 throughout, to feed the record strip by seven steps whereby the last line of print is moved into a window in the cash register. A second pawl (44) on the segment (32) rotates a ratchet (42) on the shaft (4) to drive a shaft (22) through gears (46), (47) during counterclockwise movement to feed the voucher strip by one step, Fig. 5 (not shown). The ratchet 42 is locked during clockwise movement. During total taking, rod 24 is operated to pivot the support 10 and press printing roller 14 against the voucher strip during clockwise rotation of the roller 3 to feed both strips forwardly by seven steps and print fixed information on the voucher strip.

Title: Improvements in or relating to keying circuits for oscillators
IPC: H05B6/04
Filed: 1951-02-22
Abstract: 687,038. Valve generating circuits; keying carrier frequencies. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 22, 1951 [May 15, 1950], No. 4299/51. Classes 40 (v) and 40 (vi). A valve oscillator is keyed by providing a negative grid bias from a portion of a resistor connected across a negative voltage supply and connecting a valve across the portion of the resistor, the resistance of the valve being varied to vary the bias. The bias of a conventional oscillator 1 is derived from a potentiometer 15, 16 connected across a negative voltage source 13, and a normally non-conducting valve 20 is connected across resistor 16, the oscillator thus being normally inoperative. However, when a switch 47 is momentarily moved from its neutral position to contact-point 46, an A.C. voltage is applied to the control grid of a thyratron 33 to render the thyratron conducting. A bias E 3  supplied through a voltage divider 24 from a rectifier 27 is thus short-circuited and valve 20 accordingly conducts. The current it draws through resistor 15 reduces the bias applied to the oscillator valve and thus allows it to operate. Oscillation continues until the switch momentarily is moved to point 48 to apply an A.C. extinguishing voltage to the anode of the thyratron. In the event of the switch being moved to point 48 at the point in the A.C. cycle which makes the anode of the thyratron positive the current drawn by the anode is limited by a resistor 52 and by saturation of the core of transformer 40. The valve 20 also operates to maintain the grid current constant (for example with changes of the load 4) since any increase in grid current increases the voltage drop across a cathode resistor 23, thus biasing the valve 20 back and increasing the effective grid resistance.
