Title: Improvements relating to cotton gins
Inventor: BIMBRAH BALWANT SINGH
IPC: D01B1/04
Filed: 1959-06-29
Abstract: 893,136. Cotton gins. UGANDA CO. Ltd. June 10, 1960 [June 29, 1959], No. 22173/59. Class 120(1) In a cotton gin comprising a feed hopper and an endless belt or feeder lattice by which seed cotton is lifted from the base of the hopper and allowed to fall to the vicinity of a roller and knife assembly which strips the fibre from the seed, a cyclically operated clutch associated with the lattice driving shaft causes intermittent operation of the feed mechanism. Interruption of the lattice drive facilitates escape of stripped seed from the vicinity of the stripping knife and roller without its being intermingled with newly fed seed cotton on the grid. In the mechanism shown, a worm wheel 25 is rotated by a drive from sprockets 20, 22, chain 21 and worm 24 so that a cam 27 coacting with a roller 28 periodically and momentarily moves a lever 29 about a pivot 31 to disengage a spring-loaded clutch member 18 from a member 17 and thereby interrupt the drive from gear 12 to lattice driving shaft 13.

Title: Improvements in or relating to automatic grid making machines
IPC: H01J19/00
Filed: 1948-08-26
Abstract: 710,409. Making grid electrodes. SYLVANIA ELECTRIC PRODUCTS, Inc. Aug. 26, 1948 [Sept. 3, 1947], No. 22566/48. Classes 83 (2) and 83 (4) A machine for the automatic production of grids, Figs. 16, 17, for electric discharge devices, comprises tools 44 for notching the side rods R, winding means for laying the grid lateral L, tools 46 for peening or swaging the rods to grip each lateral turn, tools 48, 50 for parting unwanted turns of the lateral between grids, a tool 52 for picking these loose turns and means for stopping the machine in the event of discontinuity in the supply of rods or lateral. The rods R are drawn through the machine by cyclic movements of heads 54, 56 carrying gripping jaws and arranged to operate as described in Specification 710,408. The rods R move along grooves in a mandrel 30, with which the notching, peening and parting tools co-operate, Fig. 15. Windings with a pitch of 70 turns to the inch are produced using freely-mounted notching and peening discs made from 1/16. inch stock, these tools being mounted on slides converging towards the mandrel between one and two degrees. Each of the discs 44, 46 is continuously reciprocated by an eccentric drive from a pinion 94, Fig. 4, and the tool is retracted after the passage of each grid by upsetting a toggle-link 106, so that between grids the notching and peening discs fail to reach the rod R. Rotation of a calibrated stop 128 affords accurate adjustment of the stroke of the notching (or peening) disc ; adjustment lengthwise of the mandrel being made by rotation of a screw 142, movement of which is indicated on a micrometer gauge 140. Variable-pitch winding is achieved by cyclic movement of the winding head 32 against a spring 173 and of the peening-disc mountings against springs 152, to ensure that the lateral wire L is correctly laid in the notches, turn after the notching, and that the wire is correctly peened. The tools 48, 50, Fig. 7, for parting the loose turns are operated cyclically when a continuously oscillating actuator 178 is so raised that it engages the depending portion 193 of a slide 174 carrying the tool and moved against a spring 176. The stroke of the cutter, Fig. 14, may be accurately adjusted by rotation of a graduated member 206. The severed turns are removed by a picker, Fig. 11, which is reciprocated cylically by hydraulic means, the jaws 246, 248 being moved with the piston 212 only whilst a collar 242 moves between stops 238, 240, the jaws being opened and closed respectively by a spring-urged radial slide 252 as the stops are reached. This picker is described and claimed in Specification 710,410. A break in the wire L interrupts a circuit 288, 284, 262, L, 30, 24, Fig. 18, to trip holding relays and thus stop the machine. Similarly, the machine is stopped when a switch 302 is operated in the absence of the wire R.

Abstract: 682,733. Supply systems for consumption apparatus; rectifying. RESEARCH CORPORATION. Sept. 14, 1950, No. 22637/50. Classes 38 (ii) and 38 (iv). To increase safety to personnel an electrical precipitator supply system comprising a transformer and a rectifier has switch means to ground the output circuits of both components. As shown, precipitators 31, 32 are supplied by a transformer 10 and a commutator rectifier 15 in a ground return circuit. The rectifier comprises input shoes 24, 25 connected to transformer terminals 13, 14, and output shoes 26, 28, and 27, 29, respectively connected to the precipitators and commoned to ground, contact being effected by conducting tips 22 interconnected by jumpers 23 and carried by rotors 19, 20 on a shaft 18 driven at one-half the cyclic rate of the single-phase A.C. supply 11 by a synchronous motor (not shown). The grounding means comprises four terminals 44d ... 44g, each consisting of two bevelled discs spring- loaded together, and, respectively, connected to rectifier input shoes 24, 25 and rectifier output conductors 60, 33, are engaged by switch blades 70, 71, 76, 77 supported on grounded shafts 72, 64, 52 inter-connected by gears 78 ... 81 and rotated by a lever 73 for simultaneous making of all the contacts. The H.T. electrodes of precipitators 31, 32, are each supplied with halfwave unidirectional current pulses via contact blades 50, 36 and terminals 44, 44a ... 44c similar to the grounding terminals. Terminals 44, 44b are carried by insulators 35, 59 separately rotatable by levers 54, 63 via the shafts 52, 64 and bevel gear-boxes 53, 65, whereby rotation of the former insulator connects blade 36 to terminal 44b to supply full-wave current to precipitator 31 and a blade 43 engages terminal 44a to ground precipitator 32. Alternatively rotation of the insulator 59 has the reverse effect. In modifications the commutator rectifier is replaced by four vacuum tube rectifiers in open bridge connection and two such arrangements shown may be interconnected by similar switching arrangements to 35, 44, &c. so that each of four precipitators may be supplied either from its own rectifier or that of its complementary precipitator of the other system.

Patent GB-228632-A (GB)
Abstract: 228,632. Krause, A. C. Nov. 8, 1923. Factory and like time recorders.-A recorder having a moving card carriage and means for preventing a record being made except when a pawl projecting into the card carriage is moved by a properly inserted card comprises a cardcarriage 10 slidable on bars 11 and having a bracket which extends between lugs on an operating handle 12 slidable on a bar 13 so that by moving the handle laterally the card is moved laterally with respect to the printing hammer 17. Downward movement of the operating handle in any lateral position depresses a pin 18 and rocks a lever 19 fast on a shaft 20. Pivoted at 25 to the lever 19 is a trip lever 24 the part 23 of which contacts with a lever 22 on the shaft 21 of the printing hammer 17, so that this shaft is turned against the action of a spring 26 until the lever 22 is released, when the hammer strikes the card against a type-wheel. A connecting rod 28 communicates motion from the lever 19 to a frame 29 which causes a cutter bar 31 to cut off a piece from the card. Slidably mounted by a pin-andslot connection on the card carrier is a bar 33, Fig. 6, kept in its uppermost position by a weighted lever 35 acting on a pin 37 projecting from the bar. A pawl 38 on the bar extends into the card carriage immediately below the path of movement of the card-cutter 31 so that the inserted card pushes down the bar 33, and through a push-rod 40 depresses a pivoted lever 41 whose end is in the form of a flat plate 44 of sufficient width to allow movement of the card carrier without the rod 40 moving off the plate. The shaft 42 of the lever 41 carries a lever 45 having a stop shoulder 46 adapted when the lever is raised, Fig. 2, to be in the path of a pin 48 on an arm 47 fixed to the shaft 21 of the printing hammer, so that if a card is not properly inserted the hammer is prevented from completing its printing movement. When the bar 33 is depressed the stop 46 is moved out of the path of the pin 48 so that printing can take place. The lever 45 is retained in its depressed position after the card has been cut, by pin 54 on a lever 53 fixed to the shaft 20 engaging with the upper surface of a lever 56 connected to the lever 45 by a link 55. If the lever 45 has not been first depressed through movement of the bar 33, the pin 54 has no action on the lever 56, as shown in Fig. 2. In a modification the obstructing means are arranged to act on the operating handle.
