Title: Improvements relating to spot welding
Inventor: WARING FRANK EDGAR
IPC: B23K11/28
Filed: 1955-09-28
Abstract: 801,594. Welding by pressure and fusion. TRIANGLE PRODUCTS, Ltd. Sept. 17, 1956 [Sept. 28, 1955], No. 27569/55. Class 83 (4). In spot welding using two non-consumable prodding electrodes connected by flexible cables to a transformer on the floor or other support to effect two welds simultaneously, the electrodes are carried one in each of the operator's hands with switch means in one cable or on one electrode welder within reach of the operator's hands and with the electrodes in contact with the same side of the work the operator switches on the current to effect the welds. Two cores 2, 3 bound together over part of their length to form a cable 1 have lugs at one end attached to a transformer 6 and are connected at the other end to electrode holders 4, 7 carried in the operator's hands. The electrodes in the holders may be renewable. A thumb switch 9 in the holder 4 is connected to the transformer control circuit by a lead 10 enclosed within the cable 2 and having a plug inserted into the control circuit. The current may be supplied to the electrodes for a predetermined time or for as long as the switch is pressed. Instead of the thumb switch a switch operated by a tighter grasp of the hand may be employed. The switch lead may bewound about one of the cores.

Title: Improvements in apparatus for securing the starting threads for a fresh set of cops or like in a winding machine
IPC: B65H54/14
Filed: 1935-10-07
Abstract: 453,678. Winding yarns. REINERS, W., 214, Bahnstrasse, Gladbach, Munich, Germany. Oct. 7, 1935, No. 27667. Convention date, Nov. 29, 1934. [Class 120 (ii)] The threads extending from the thread guides of a winding machine to the wound cops are, on the completion of a set, secured by clamping devices, one for each spindle, each device comprising a fixed jaw and a movable jaw; the movable jaw in its position of rest faces the thread between the guide and cop and is moved from that position part-way round the spindle into contact with the fixed jaw so as to loop the thread and clamp it against the fixed jaw, the thread being then ruptured for the doffing of the completed cops. As shown in Figs. 1 and 2, the threads are engaged by movable jaws 22 having T-shaped ends 23 and carried by a bar 21 mounted in levers 19 at the ends of the machine frame. One of the levers is slid and rotated in a gate 20 by hand or automatically so that the threads are taken by the jaws 22 and clamped against the fixed jaws 24, which may be resilient; after the threads are ruptured, by turning a hand wheel 15 on the spindle-driving shaft 1, the spindle bearings 9 are retracted and the completed cops 10 drop into a receptacle or on to a conveyer belt, the thread ends from the guides 4 being clamped by the fresh cop tubes against the spindle ends 26. In another arrangement the movable jaws are fixed to a rod actuated by crank gearing and a cutter is arranged adjacent each resilient fixed jaw so that as the movable jaws clamp the looped threads against the fixed jaws, the threads extending from the jaws to the completed cops are severed. In a further form, the movable jaws are pins fixed to wheels mounted on the spindle and moved therearound to clamp the threads in loops against the fixed jaws ; the wheels may be formed as pinions, engaging, and actuated by, a rack and the threads are ruptured by turning the spindledriving shaft.

A ball projecting machine comprises a sinuous ball reservoir 1, 3, 5, a receptacle 35 for transporting a ball 58 from the delivery end 15 of the reservoir to a firing position on parallel tracks 52, 54, and a striker arm 83 pivoted at 91. The striker arm is normally urged towards its striking position by an adjustable spring 93, and is periodically retracted from this position, and subsequently released to fire the ball, by a motordriven cam 71 cooperating with a follower 79 on a bracket 75 linked to the striker arm. The shaft 43 mounting and driving the cam is also linked to the supporting arm 37 of the receptacle 35 for for pivoting the arm about pin 19 in synchronization with movement of the striker arm. A device 11 for controlling the emission of balls from the reservoir outlet 15 is also operated by the supporting arm 37, via link 47, and a projection 27 on the mounting bracket 17 of the device. An adjustable plate 60 mounted between tracks 52 and 54 serves as a means of varying the trajectory of balls leaving the machine, and the latter is entirely enclosed in a casing 12 provided with an inlet 13 for balls and a control panel 123.

Abstract: 534,042. Centrifugal machines. HOLMES & CO., Ltd., W. C., SYKES, W., and HOLMES, F. B. Oct. 12, 1939, No. 27745. [Class 23] Suspended particles are separated from gases by means of apparatus having rotors arranged in parallel in a casing, and each forming a cage with a peripheral wall of slats or blades 3 which extend in an inclined direction with respect to the periphery. These blades may be of the form described in Specification 514,320. Four rotors 2, 2a, 2b, 2c are arranged in each of two casings, and each casing is divided by a vertical screen 4 so that two rotors are on each side of the screen. The inlet main 5 has branches to conduct the flow to a point midway between each two rotors, and while the machine is working the suspended particles are thrown out and drop through the casing to the hopper 12. The clean gas passes through the rotors to axial discharge conduits 7. The discharge from each set of four rotors is combined in a conduit 8 leading to the discharge pipe 9 which is connected to the inlet of a fan. Corresponding rotors in the two casings are on a common shaft 11 supported in bearings 10 external to the casings.

Abstract: 1,010,658. Pulse circuits. CESKOSLOVENSKA AKADEMIE VED. July 20, 1962 [July 21, 1961], No. 27936/62. Heading H3P. In a circuit for generating periodic groups of randomly occurring uniform pulses, pulses from a noise generator are shaped by a Schmitt trigger then fed to a gated limiter, the output of which is controlled by regularly recurring keying pulses, the output of the limiter being fed to a further Schmitt trigger shaping circuit. Fig. 2 shows a suitable gated limiter in which valve E1 is normally conductive and E2 normally cut off so that negative-going pulses from the Schmitt trigger are limited by anode current cut-off of valve E1 and passed to an output terminal 3 except when a positive-going keying pulse is present at terminal 2 when valve E1 will be cut off by E2. The upper frequency limit of each successive stage should be greater than that of the preceding stage.

Title: Improvements relating to alternating current voltage regulating systems
IPC: H02M5/27
Filed: 1955-10-04
Abstract: 821,833. Variable voltage supply systems; converting. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., and KING, K. G. Oct. 4, 1956 [Oct. 4, 1955], No. 28225/55. Classes 38 (2) and 38 (4). A system for regulating an A.C. supply comprises a pulse width circuit modulating the supply of two or more times the fundamental frequency and a filter circuit to smooth the output. The supply is connected to terminals 9, 10 and is switched by transistor V2. Rectifiers M1, M2 connect the negative terminal of battery B2 to whichever collector is more positive, maintaining V2 at cut-off. V2 is switched by pulses of negative saturating base cement from battery B1 through a resistor R2 and a second transistor V1, which is triggered by a pulse generator 5. The supply, chopped by V2 is applied to the load 6 through a filter circuit 11 which attenuates frequencies other than the fundamental. Transistor V2 may be replaced by two transistors arranged in pushpull and the transistors may be replaced by valves. In the case of a source frequency of fifty cycles per second, the pulse generator may trigger V1 at a frequency of say, one thousand cycles per second.

[Also in Group XXIII] Continuous lengths of angle-section glass or thermoplastic strip are produced by flowing the molten material between pairs of rollers 6, 7 ; 13, 14 ; 18, 19 and supporting it until it is sufficiently set to support itself. The roller 6 has a small peripheral groove midway along its length and the roller 7 is plain. This has the effect of producing a ribbon that is flat except for a tapered rib extending axially along its upper face. The other pairs of rollers are formed with complementary grooves and conical portions of increasing depth/height whereby the glass strip being formed becomes bent to the desired angle and the bend, when completed, is shaped as shown in full lines in Fig. 5 instead of the shape shown in broken lines resulting from bending a preformed flat strip.
