Title: Improvements in or relating to electric gas discharge tube counting or distributing circuits
Inventor: BEESLEY JOHN HENRY
IPC: H03K23/82
Filed: 1955-05-10
Abstract: 785,799. Electronic counting apparatus. GENERAL ELECTRIC CO., Ltd. April 12, 1956 [May 10, 1955], No. 13522/55. Class 106 (1). An electric counting or distributing circuit comprises at least two (n) input leads and a chain of gas tubes, adjacent tubes being associated with different ones of n signal-carrying leads and n control devices which, acting in response to signals on the input leads, apply signals of a predetermined size to the signalcarrying leads so as to cause the gas tubes to fire in sequence, each newly conducting tube extinguishing a previously-conducting tube. In the described embodiment n=2 and each input signal takes the form of a positive pulse at a terminal 1 followed by a similar pulse at a terminal 2. These are applied over leads 24 and 25 respectively, in parallel, to two control devices, only one of which (22) is shown in Fig. 1 and in detail in Fig. 5. The counting or distributing chain of tubes 11, 12, etc., is conposed of two groups, the odd-numbered tubes (represented by tube 11) having their trigger elements connected to a line 9 which forms the output line of control device 22, and the evennumbered tubes 12 &c. having their trigger elements controlled by the other control device (23, Fig. 2, not shown). Similarly, the cathodes of the " odd " tubes 11 &c. are connected through rectifiers 29 to control the input to the second control device (23, Fig. 2, not shown) while the cathodes of the even tubes are connected through rectifiers 30 to a line 27 which ensures that the first tube 41 of the control device 22 will not be fired unless an " even " tube is conducting in the counting chain. The arrival of the first positive pulse of an input signal on line 24 fires tube 41 and the next positive pulse following on line 25 fires tube 42, extinguishes tube 41, and supplies an output voltage on line 9 which steps the counter on from an " even " tube discharging to the next " odd " tube discharging. A slightly modified arrangement of control circuit (Fig. 6, not shown) is described for use with an input circuit in which an incoming signal on terminals 1, 2, Fig. 4, energizes a relay A causing earth to be connected to line 25 and then, immediately afterwards, removed from line 24.

IPC: F02M7/16
Abstract: 135,453. Ateliers H. Cuenod Soc. Anon., (Assignees of Juillard, E.). Nov. 21, 1918, [Convention date]. Spray carburettors.-The fuel supply is varied simultaneously with the passage around the nozzle and also independently by the engine suction to prevent an excessive flow of fuel when the suction is high. The casing a is formed in one with the float chamber d and encloses four symmetrical pieces j<1> which produce the variable passage j around the nozzle h. These pieces have, formed throughout their depth, slots j<2> which engage pins fixed to or formed integral with the top of the casing a. Further, each piece has in its lower face a groove j<3> which engages a transverse projection j<4> of a small plate j<5> on an adjacent piece. The bottom of each piece has also a pin j<6> which engages a cam-groove in a plate k which can be rotated by an arm m. Each of the pieces has a cavity j<7> which fits over the nozzle h when the passage j is closed. By rotating the arm m the pieces slide over and partly rotate abcut the fixed pins, and as a consequence the size of the passage j is varied. The fuel nozzle h has sliding over it a sleeve l which carries a tapered fuel control valve i<1> and is slotted at its upper end to allow the fuel to escape. The sleeve has an arm l<2> a finger l<3> on which engages a plate p inclined in and at right-angles to the plane of the paper and resting through a projection p<2> on the upper plate of a flexible chamber 1. This chamber is rrounted adjustably on an arm 3 and its interior communicates through passages 2<1>, 3<1>, 5 with the induction passage at the bottom of the tapered outlet b<3>. As the arm m is rotated, the finger l<3> moves over the plate p and varies the fuel outlet and if the suction becomes high, the upper plate of the chamber 1 is drawn down and the sleeve l and fuel valve are lowered independently to reduce the fuel supply. In a modification, the fuel outlet is controlled by rotation of the sleeve instead of by the axial movement of a valve carried thereby.

Abstract: 540,659. A.C. signal receivers. SIEMENS BROS. & CO., Ltd., and REED, M. Aug. 29, 1940, No. 13615. [Class 40 (iv)] In a system employing alternating current for impulsing and other signalling, the singlephase line current is converted at the receiver into three-phase current which controls the impulse-responding relay S through a threephase rectifier comprising six units RA .. RF arranged to give full-wave rectification. It is assumed that the signalling frequency is located in the gap between two speech bands in a multiplex system, and that it is x cycles above or below the frequency F of a carrier leak within the gap, x being in general less than 100. At the receiver, the input passes after amplification to parallel circuits in which the frequency x is obtained by heterodyning with the frequency F in frequency-changers FCA, FCB and selecting the difference frequency by tuned circuits QA, QB. The frequency F is supplied to FCA, FCB in quadrature, so that the output transformers TRA, TRB receive currents in quadrature through amplifiers VA, VB. These transformers are connected according to the Scott method to produce a three-phase circuit for feeding the three-phase rectifier RA ... RF.
