Title: Improvements in or relating to multi-electrode gaseous-discharge tube circuits
Inventor: THOMAS DAVID GURNEY ARNOLD
IPC: H03K29/00
Filed: 1951-02-23
Abstract: 729,638. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 22, 1952 [Feb. 23, 1951], No. 4385/51. Class 106 (1). A circuit comprises a pulse generator (13), first switch means (66) to direct a pulse train from the generator to move the discharge in either one or the other of first (51) and second (14) multi-cathode gas-discharge tubes, second switch means (59) associated with the output cathode of the first tube to switch pulses occurring after the discharge reaches the output cathode to move the discharge in the second tube, means (23... 32) associated with the main cathodes of the second tube to mark any one of these cathodes whereby pulses occurring after the discharge reaches the marked cathode move the discharge in the first tube, and identifying means (33 ... 37) associated with the main cathodes of the second tube to identify the cathode on which the discharge comes to rest. A large number of units 11 may form a data storage for an electronic calculating machine. Data to be entered is set up, either by hand or by sensing record cards or tape, on switches such as 23 ... 32. After zeroizing the tube 14 under control of a circuit 16, the discharge is stepped on by pulse pairs from the generator 13 until the cathode marked by the closed switch 23... 32 is reached, when a signal passes via an amplifier 15 to the switch circuit 66 which now causes the stepping pulses to be fed to a selected tube 51 as well as to the tube 14. Thus, when a train of ten pulse pairs has returned the tube 14 to zero, the tube 51 will be set up to represent the complement of the number selected by one of the switches 23 ... 32. The number registered in the tube 51 can be read out to the tube 14 in a similar manner, amplifying valves 33a and slow-release relays 33b arranged for " five-hole " coding, enabling punching or printing mechanism to be actuated. A switch 67 provides for " add " or " subtract conditions between the tubes. Specification 699,696 is referred to.

Class 64(2) Air passes through a filter 2 and blower 1 to be heated electrically in a tube 3 under the control of a temperature - responsive element 9 before passing to an open chamber 5 containing cups 26 of granulated synthetic resin for moulding gramophone records. The cup bottoms have perforations, e.g. concentric slots. A sleeve 8 connected to the tube 5 slides on a column under the control of a lever 10 so that the tube can be lowered away from the hot air pipe to enclose a fresh cup of resin granules on a plate 7. The fresh cup is held in the tube 5 by spring devices and the top cup from the tube is exposed for removal and emptying by the operator. In Fig. 2 (not shown) the hot air is fed to the bottom of the tube from which a cup is forced for removal by the operator when the tube is raised and the top cup is thereby forced against a stop of a measuring and filling device incorporated at the base of a storage bin of resin granules. The movement of a lever which causes these operations simultaneously causes a quantity of resin to be measured into the top cup.

Filed: 1963-02-07
Abstract: 986,773. Valves. GUMMERS Ltd. Jan. 8, 1964 [Feb. 7, 1963], No. 5017/63. Heading F2V. When the control knob 68 of a mixing valve is turned from the " off " to the " cold " position the lift valve 42 and a slide valve 22 are elevated by a spring 23, however, the hot water ports 30 remain closed and cold water ports 32 open. The interior of the valve 22 leads to a mixing chamber 36 that is open via the valve 42 to a chamber 60 having one or two outlets, not shown. As the knob 68 is further rotated towards the " hot " position, the lift valve 42 opens to a greater extent and the valve 22 increasingly uncovers ports 32 and covers port 30 until in the " hot " position no cold water at all enters the mixing chamber. Throughout the range of movement of the knob between " cold " and " hot " a thermally responsive bellows 38 in the mixing chamber compensates for any temperature variation by moving the valve 22. The bellows acts as the interconnecting means between the two valves. The liquid temperature for any setting of the knob may be varied by adjusting an abutment 40 for the slide valve. The interior of the slide valve 22 is connected with a space therebeneath via a restriction 29. The bellows which has interior means for limiting its contraction, closes the hot water ports upon failure of the cold water supply.

Filed: 1954-02-22
Abstract: 752,363. Testing circuit breakers photoelectrically. LICENTIA PATENT-VERWALTUNGS-GES. Feb. 22, 1954 [Feb. 23, 1953], No. 5128/54. Class 40 (3). [Also in Group XXXVI] In tests on high voltage and power circuit breakers in which high potential is applied to the breaker contacts by breakdown of the gap between auxiliary series electrodes and in which the breakdown between the electrodes is initiated by deforming the field between by means of a still further electrode, a photo-electric receiver in the high-voltage circuit responds to a light flash produced by a low-voltage source to produce a pulse between one of the electrodes and the auxiliary electrode to initiate the auxiliary discharge. As shown a gas discharge tube B in a low-voltage circuit is triggered by means of a starting electrode Z. The flash thus produced is received by a photo-cell E which triggers a discharge tube T in series with the primary of impulse transformer Ti through which condenser Cz discharges, thus producing the necessary voltage pulse at the auxiliary electrode H. The discharge tube T may be of the cold cathode type.
