Abstract: 361,949. Typewriters. A. E. G.- FAHRKARTENDRUCKER GES., Hennigsdorf, Osthavelland, Germany. July 30, 1930, No. 22998. Convention date, Aug. 9, 1929. [Class 100 (iv).] A cash register is provided with means for determining and printing the product of price and quantity. A drum 1 carries removable bars 3 supporting pins 4, the bars relating to the unit price and the pins having lengths proportional to the products of price and quantity. For co-operation with these pins is a carriage 29 carrying the printing-wheels 6 set by racks 5 adapted to feel the pins. The drum is put in rotation and when a key 11 denoting the price is depressed, a circuit is prepared through a relay 75 and a pair of fixed contacts 69, 70. When the drum has reached a position such that a contact strip 72 bridges the selected pair of contacts, the relay is energized and through a pawl 81 stops the drum. At the same time a clutch sleeve 61 is forced to the left to break the drum drive and to rotate a pulley 26 driving the printing and voucher-issuing devices. The carriage position axially with respect to the drum having been previously set in accordance with the quantity, the racks 5 are now allowed by a cam 10 to advance to feel the pins and so set the wheels 6 to print on the voucher-strip. Other type-wheels set respectively by the carriage shift and by the rotation of the drum 1 print the quantity and price. The impression is made by a spring-controlled platen 18 raised and released by a cam 21. The voucherstrip is fed by printing and pressure rollers 52, 53 driven from the pulley 26 through gearing 23, 32a and is subsequently severed at 28.

Title: Improvements in and relating to electrical oscillation generators
Inventor: DAVIES DAVID LEIGHTON
IPC: H03B5/20
Filed: 1958-07-21
Abstract: 916,033. Valve oscillator circuits. SOLARTRON ELECTRONIC GROUP Ltd. July 10, 1959 [July 21, 1958], No. 23384/58. Class 40 (6). [Also in Group XXXV] In a sinusoidal oscillation generator, the voltage waveform is sampled over a small part of a cycle near a peak, compared with a reference voltage and the difference used to generate a correcting pulse which is combined additively with the generated waveform so as to maintain the sampled amplitude constant. As shown, amplifiers 10, 11 each have a phaseshift of 90 degrees with unity gain at the oscillation frequency, effected by series resistors 12, 13 and feedback capacitors 14, 15. The oscillation is maintained by a feedback amplifier 16 having unity gain. The sum of a sinusoidal output voltage from amplifier 10 and a negative reference voltage from a source 17 is applied to a gate 18. The gate 18 is opened at a positive peak of the output voltage from the amplifier 10 by an amplitude selector 23 deriving clipped positive and negative-going pulses from a summation of the output of amplifier 11, rectified by a diode 19; the output of amplifier 11, reversed in phase by an amplifier 20 and rectified by a diode 21, and a portion of the output of amplifier 10, reversed in phase by an amplifier 26 and rectified by a diode 21. The output pulse from the gate, representative in amplitude and sign of the difference between the sampled amplitude and the reference voltage is fed to the input of the feedback amplifier 16 to modify the output waveform of the amplifier 10 so as to maintain the sampled amplitude constant. It is stated that the amplitude correction can be applied n times per cycle, or every nth cycle, where n is a positive integer. To ensure constant peak amplitude from the commencement of oscillation, the oscillators 10, 11 are clamped by switches 51, 52 that are simultaneously opened to start the oscillation. Specification 849,903 is referred to.
