Title: Improvements in or relating to electrical gas discharge tube counting or distributing circuits
IPC: H03K23/82
Filed: 1953-02-19
Abstract: 734,875. Multi-stable state circuits. GENERAL ELECTRIC CO., Ltd., and BEESLEY, J. H. Dec. 14, 1953 [Feb. 19, 1953], No. 4680/53. Class 40 (6). A gas-discharge tube counting chain comprises a driving tube and a number of counting tubes the striking of the driving tube being initiated by a pulse received over a single input lead and terminated by a voltage derived from the counting chain. Fig. 1 shows a multistable state cold cathode gas tube counting circuit comprises a driving tube T1 and a chain of counting tubes T2, T3, T4..., the supply voltage X having a value sufficient to maintain and not to initiate an anode/cathode breakdown. Ionizing pulses to be counted are applied at input P and differentiated by network C1, R9 the resulting positive pulse causing driver tube T1 to strike, if it is assumed that the counting tube T2 in the chain is already conducting the voltage drop across resistor R10 and cathode resistor R6 and the positive biasing voltage Y causes tube T3 to strike, the voltage drop across the common anode load resistor R1 causing tubes T1 and T2 to be extinguished. The time constant R1, R7, C3 being such that the voltage of lead A remains below the discharge maintaining value until tubes T1 and T2 have de-ionized. Tube T3 thus alone remains conducting until a further input pulse advances the discharge along the counting chain so that tube T4 alone conducts. Rectifiers W2, W5; W3, W6, &c. thus act as coincidence gate circuits between the counting tubes. In a modification shown in Fig. 2, if it is assumed that counting tube T2 is conducting and that an input pulse applied at P and differentiated by network C1, R9 causes driver tube T1 to fire then the rise in voltage across cathode resistor R10 causes tube T3 to fire and tubes T1, T2 to be extinguished as described in connection with Fig. 1. Each of the resistors R11, R12, R13 has a value midway between the forward and backward resistance of its associated rectifiers W5, W6, W7, &c. The cathode of tube T1 is biased to a potential Y which is now derived from supply X via resistor R16 and is stabilized by tube V1.

Filed: 1927-02-21
Abstract: 270,254. Beloit Iron Works, (Assignees of Aldrich, A.). May 3, 1926, [Convention date]. Winding webs.-In a web-winding apparatus, for paper making, slitting and rewinding, or other machines, in which a winding-spindle rests upon and is driven by a pair of winding-drums, means are provided for imparting a sudden blow or kick to the wound or partly wound roll when it is desired to move it from the winding position. The web 5 passing from the slitting-device 4 is wound by the drums 6, 7 upon a winding- spindle 11 which is supported in the usual manner by brackets 18 slidable on guides 24 and connected by chains 26 to counterweights 29. The roll-kicking device comprises rollers 49 mounted on a cross shaft 48 carried by arms 45 which are secured to a shaft 36 having an arm 37 connected by a link 38 to the piston rod 39 of a fluid pressure cylinder 41 controlled by a valve 44. If the web should break, the spindle 11 is released from the brackets 18 and pressure fluid is admitted to the upper end of the cylinder 41. The arms 45 are thereby swung downwardly so that the rollers 49 impart a blow to the roll throughout its length, lifting it from the drum 7 on to the drum 6. The movement is arrested by the engagement of the spindle 11 with bars 17. Brackets 53 on these bars are then lowered to engage the spindle 11 to retain the roll while the arms 45 are returned to their normal position and the broken end of the web passed round the drum 7 and attached to the roll. The rollers 49 are again brought into contact with the roll, the brackets 53 raised, and the roll allowed to return to the winding position by again raising the arms 45. The bars 17 are pivoted to brackets 15 so that thev mav be turned down when not in use. When the roll is full, it is moved on the drum 6 by means of the rollers 49 and is then manually rolled on to a runway 51.

Abstract: 405,465. Master control of D.C. motors. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, Pennsylvania, U.S.A.-(Assignees of Storer, N. W.; 6818, Reynolds Street, Pittsburg, U.S.A.) Feb. 20, 1933, No. 5231. Convention date, March 19, 1932. [Class 38 (iii).] In order to prevent slipping of the driving wheels of an electrically driven vehicle having separate motors for each axle, portions of the series field windings of parallel connected motors are cross-connected so as to couple the axles together electrically. The invention is described with reference to a vehicle with four driving axles each driven by twin motors having armatures 1A 1B, 4A 4B, 2A 2B, and 3A 3B, the main portions of the respective series field windings being shown at F, and auxiliary portions, which are cross-connected, at f. The whole system is operated by unit and cam switches from a drum controller, and in starting the vehicle, motors on all axles are first connected in series ; subsequently motors on axles 1 and 4 and those on 2 and 3 are connected in parallel and the two parallel connected groups in series ; and finally the twin motors on all axles are connected in parallel. Intermediate control stages are provided by resistances 2, 4, 6 and 8, and inductive shunts 36-39 for the field windings. Whilst the twin motors on all axles are connected in series, cam operated switches 42ABCD are closed, and cam-operated switches 42EFGH are open so that the whole of each field winding is in series with its respective motor, but during the series-parallel, and parallel connection of the motors the positions of these switches are reversed so that field sections 1Af, 1Bf, and 4Af 4Bf are cross-connected with armatures on axles 1 and 4, and field sections 3Af 3Bf, and 2Af 2Bf are cross-connected with armatures on axles 2 and 3. The above system may be so modified that the two motors on each axle are each connected in parallel with a single motor on two other axles, so that, when portions of the fields of parallel connected motors are crossed, all four axles are electrically coupled.
