Title: Improvements relating to the production of tufted fabrics
Inventor: WOODCOCK DOUGLAS GEORGE
IPC: D05C15/00
Filed: 1960-05-23
Abstract: 910,605. Tufting-machines. SINGERCOBBLE Ltd. May 19, 1961 [May 23, 1960], No. 18051/60. Class 112. In a tufting-machine, means for moving the work or the needles across the direction of work feed is driven through a releasable clutch which is adapted to be released and re-engaged at preselected times by cyclically-operating means driven in synchronism with the work feed mechanism. A shaft 32, Fig. 4, driven by a pulley 32a, is connected via a magnetic clutch 39 to a gear-box 33, the output shaft 33a of which is connected by a driving-chain 40 to a shaft 34 carrying a radially-adjustable crank-pin 35a. A connecting-rod 36 links pin 35a to an arm 37 rigid with a slidable bar 38 adapted to impart transverse reciprocating movement to the work. An arm 41, rigid with arm 37, carries a cam block 42, and the arrangement is such that, when bar 38 is in the middle of its stroke, cam 42 engages a roller 43 on one arm of a bell-crank lever, the other arm 44 of which thereby engages the operating knob 45 of a micro-switch 46 to close the latter. A shaft 11, Fig. 6, is driven in synchronism with the work feed by a chain 9, one side of which carries a series of cams 18a, and the other side of which carries a series of cams 18b. A cam 18b in its uppermost position coacts with a roller 21a on a lever 21 to raise the latter about its pivot 22. A flange 23 on lever 21 thereby engages an operating knob 24 to close a micro-switch 25, and a pin 29 on a spring- biased suspended link 30 enters a notch 28 in lever 21 to hold the latter in the raised position. Switches 25 and 46 are in circuit with a solenoid 26, Fig. 11, which is thereby energized on the closing of switch 46 when bar 38 is next in its mid-position, to open a switch in series with the energizing coil 27 of clutch 39 and to close a switch in a holding circuit 47 shunting switch 46. The movement of bar 38 is thus halted and the machine produces straight lines of tufting. When the next cam 18a reaches its uppermost position it coacts with a roller 20a on a lever 20 to raise the latter about its pivot 22. The chamfered end 31 of lever 20 then coacts with pin 29 to release lever 21, when switch 25 opens to cause re-energizing of coil 27. Bar 38 is then driven for producing wavy lines of tufting. In a modification, Fig. 9, a disc 48 rigid with shaft 34 carries a cam lobe which, in the midposition of bar 38, coacts with a roller 49 on one arm 50 of a double-armed lever to raise the latter against spring means 53, whereby a cam surface 52a on the other arm 52 coacts with the operating knob 45 to close the switch 46. Specification 910,604 is referred to.

Title: Improvements in or relating to thermionic amplifiers
IPC: H03F3/28
Filed: 1923-07-17
Abstract: 222,981. Voigt, P. G. A. H. July 17, 1923. Thermionic amplifiers. - In a low-frequency power amplifier, the ends of the secondary of the input transformer T are connected across the grids G of two valves arranged differentially, a connection being taken from one end of the secondary to the filament through a high resistance R (or other impedance) and biasing cells C. Each half cycle of the input voltage throws one or other of the grids positive, whereupon the resultant grid current automatically regulates the initial grid bias proportionally to the impressed voltage. By suitably adjusting the permanent bias from the cells C each valve can be used to amplify both halves of the input wave. In the case of an overload both valves become operative without giving rise to distortion. Should distortion occur it is accompanied by rectification, and this is shown on the indicator M. For smaller voltages only one valve is used, a condenser being inserted in the circuit in place of the grid-filament path of the second valve.
