Title: Improvements in or relating to bobbin changing mechanism for automatic looms
IPC: D03D45/20
Filed: 1945-08-14
Abstract: 597,669. Automatic bobbin changing in looms. CO-OPERATIVE WHOLESALE SOCIETY, Ltd., SOUTHWELL, T., WILLIAMSON, F., and JARMAN, A. Aug. 14, 1945, No. 20853. [Class 142 (iii)] In a multi-compartment bobbin magazine, the selected bobbin 13 falls against spring fingers 18 and a pusher 20 then moves it positively into the path of the transfer hammer 16b. A bobbin is released by rotation of a carrier 14 through 180‹ to the position shown (in which it supports the remaining bobbins in the compartment), the rotation being effected by a vertical rack meshing with a pinion on the carrier and actuated through an electro-magnetic clutch from an oscillating shaft 24. Upward movement of the rack also depresses, through an associated lever 30, a plunger 29 which closes a clutch 28, so that when the shaft 24 reverses to return the carrier 14 to its normal position, the pusher 20 is operates through a fork 23 and lever 19.

Title: Constant energy pulse generator
IPC: H03K17/0814
Filed: 1963-05-27
Abstract: 1,012,099. Transistor pulse and gating circuits. SPERRY RAND CORPORATION. May 27, 1963 [June 8, 1962], No. 21031/63. Heading H3T. A circuit for generating pulses having a constant voltage/time integral comprises a first switching device (such as transistor 26) switched on by input pulses and having regenerative feedback via a transformer 10, the circuit controlling the conduction of a second switching device (such as transistor 38) which supplies pulses to an output terminal 40. A saturable inductor 30 is connected across one of the windings of transformer 10 so as to maintain the voltage/time integral of the output pulses independent of the supply voltage at terminal 28. Transistor 26 is turned on by pulses fed to terminals 22, 24 and coupled to the base via windings 12, 18 of transformer 10. Transistor 38 is turned on at the same time by voltage induced in winding 20, initiating an output pulse at terminal 40. Transistors 26, 38 remain conductive until a saturation current has built up in inductor 30 when transformer 10 becomes short circuited, turning off transistor 26, 38 and terminating the output pulse at terminal 40. The switching of transistor 26 is expedited by inductor 36 and regenerative feedback between windings 16, 18. The saturable inductor 30 ensures that the duration of output pulse is inversely proportional to the supply voltage at terminal 28 and hence inversely proportional to its amplitude. The energy (voltage/time integral) is thus constant. Transistor gating circuits.-Fig. 2 shows an arrangement for controlling the writing heads 48, 50, 52 of a magnetic recorder. Constant energy clock pulses are generated by a circuit 46 of the type shown in Fig. 1 and fed to the centre taps of windings 48 . . . 52. Gating transistor 60 or 62 is turned on when it is desired respectively to record a " 1 " or " 0."
