Abstract: 446,904. Soldering armatures. RANU, S. P. S., G.1.P. Railway, Matunga, Bombay, India. Nov. 7, 1934, No. 31962. [Classes 83 (ii) and 83 (iv)] In a machine for soldering the ends of armature coils to commutator segments by a jet of molten solder, the armature shaft is supported at one end by a jack and is rotated at the other end in a headstock, and the solder is fed through a nozzle by gravity from a reservoir into which it is pumped from a heating tank. The armature shaft 96<A> may be supported at one end on a pair of parallel rollers 110 carried by a ratchet operated jack 13 and is secured at the other end by a bolt 78 in a socket 96, whch is rotated by a stud 95 on a member 94 driven by worm reduction gear and friction gear 85, 125 from an electric-motor 126. The socket may be carried by a spherical ring 216, so that the work may be rotated in an inclined position. The jack and head stock 81 may be fixed to or adjustable along the bed 20. A slide rest 102 which is traversed on the bed by rack-and-pinion mechanism from a handle 99, supports at one side a bracket 71, which is vertically adjustable by a hand wheel 104 through bevel gear 27, 74 and a screw 73. To the bracket is bolted a solder tank 31, which has a heat insulating casing and is heated electrically. A thermo-electric switch may be provided. In the tank is immersed a pump body 255, Fig. 6, which is secured to the tank by bolts 33, 56. To the pump body is fixed a solder reservoir 257, a solder discharge pipe 241 and nozzle 239 and a pan 238 and pipe 256 for return of surplus solder to the tank. The reservoir and pipes are kept hot by electric heating elements. The pump ram 194 is connected to a spindle 45 pinned to a connecting rod 177 driven by a crank-pin 209 on a friction disc 35 rotated by an electric motor 155, the spindle 45 sliding in a guide attached to the tank 31. When the ram rises solder is drawn from the tank through a non-return valve 313, Fig. 18, and when the ram returns the solder is forced past a valve 253 into the reservoir, from which it descends by gravity through the tube 241 and jet 239. The valve 313 may be held open to stop operation by a hand-operated lever 312, and the valve 253 may be kept closed by the operator pressing on the knob 269. Detachable nozzles 239 of various sizes may be used and the angular position may be varied by rotating the tube 241 by way of the knob 234. An adjustable wire 237 is mounted on the nozzle support so as to direct surplus solder from the work into the pan 238. The reservoir may be connected to a number of nozzles for soldering a number of armatures simultaneously or a number of pumps and reservoirs may be used. The pumps may be single or double acting.

Title: Improvements in or relating to pulse generating circuits
IPC: H03K3/55
Filed: 1962-08-21
Abstract: 1,010,328. Pulse generating circuits. SPACE TECHNOLOGY LABORATORIES Inc. Aug. 21, 1962 [Aug. 21, 1961], No. 32123/62. Heading H3P. A pulse is generated by discharging a capacitor into a clipping device, the pulse being maintained by discharging a longer time constant circuit into the clipping device and terminated by short circuiting the clipping device after a period determined by a delay generator. As described, the thyratrons 13, 27, 33 are operated in a non-standard manner, the control electrode 16a being used as a primary anode and the shield 14 being used as control electrode. The thyratrons 13, 27, 33 are normally non-conductive, hence capacitors 19, 21, 24 are normally charged. The thyratron 13 becomes conductive when an input trigger pulse is received, discharging capacitor 19 via the capacitance 37 of the output circuit. The amplitude of output pulse is limited by the Zener diode 36a. The pulse is maintained by the comparatively slow discharge of capacitor 21 via resistor 22 and the thyratron 13. Capacitor 24 discharges via inductor 23 and the thyratron 27 (used as a diode), the oscillation being terminated after one-half cycle by thyratron 27 becoming non- conductive. Thyratron 33 becomes conductive at this instant, short circuiting the output terminals and terminating the pulse. Specification 987,268 is referred to.

A stringer for a sliding clasp fastener comprises a carrier tape and U-shaped coupling elements formed from a single plastics filament and secured to the carrier tape each coupling element having one limb provided with an extension which is folded to a position in which an end portion is substantially parallel to and in the same plane as the limbs of that coupling element the carrier tape being folded around the end portion of each extension substantially to conceal one side of the U-shaped coupling elements. In one construction, Fig. 5 the extension 3a of said limb 3 of each U-shaped element 2 is folded around the other limb 4 of the element so that the element with its extension forms a substantial G shape, the carrier tape 7 after being folded around the end portion of each extension terminating between the limbs of each U-shaped element. The elements are either formed to shape first and the tape fed into the elements or alternatively the filament is first bent to a regular meander form which is then bent about a longitudinal axis to U shape and the tape is sewn between the limbs 3, 4 and the extension of each element is bent around its limb 4. In a second construction, Fig. 10 the extension 22 of the limb 24 of each U-shaped element is folded away from the other limb 23 so that the element with its extension forms a substantial S shape the carrier tape 29 being folded round the end portion of each extension and a spacing braid 28 being located between the limbs of the U-shaped elements. The elements are secured to the tape by one or more rows of stitching and each element is formed with a coupling projection. To prevent tilting of the elements on the tapes, in the case of the G-shaped elements braids can be stitched to each stringer so that they abut when the two stringers are coupled together: alternatively the elements have depressions formed in the base portion of each U-shaped element so that the edge of the opposite tape engages the depressions.

Title: Improvements in or relating to apparatus of the kind responsive to impulses amplitude modulated on to an electric carrier signal
IPC: H04L27/08
Filed: 1952-12-23
Abstract: 767,500. Code telegraphy. GENERAL ELECTRIC CO., Ltd., and ROBINSON, A. S. Dec. 22, 1953 [Dec. 23, 1952], No. 32569/52. Class 40 (3). A receiver for a system in which telegraph impulses are transmitted as amplitude modulations of a carrier-wave comprises a first value which passes the modulated carrier and the output of which is fed to the control grid of a second valve over two paths, the first path including an unturned detector and a delay network and the second path including a rectifier for producing a bias voltage fed in opposition to the first voltage. As shown, the anode circuit of the first valve 4 which receives the incoming signals from a transformer 2 includes a step-down transformer 8 with its secondary winding connected to a rectifier arrangement 11, the output of which is applied via delay network 13 and resistor 17 to the grid 23 of a pentode 24 arranged to operate as a triode amplifier. The output of the valve 4 is also fed from an adjustable anode resistor 9 via rectifiers 20 and 21, arranged as a voltage doubler, and capacitor 28 to an input resistor 22. The network 13 is arranged to provide a delay of 1 to 4 seconds. The build-up time of the bias voltages a, b, Fig. 1, is arranged to be shorter than that of the corresponding voltage c, d, applied to resistor 17 and to have a peak amplitude approximately one half that of these wave forms. The voltages applied to the grid 23 of the valve 24 are in opposition so that the resulting wave forms e, f derived from the received impulses and original waveforms c, d respectively reduce the current through the winding 25 of the relay 26, and the current through the biasing winding 27 operates the relay to marker. The arrangement is such that the signal transits at A, B are substantially independent of the amplitude of the received signal. In the absence of a signal impulse the voltage on the grid 23 is controlled by a rectifier 33 so that the valve passes current to operate the relay 26 to space. In a modification, Fig. 2 (not shown), the voltages for the two paths are derived from the secondary windings of transformers whose primaries are connected in series in the anode circuit of the valve 4.
