Title: Improvements in or relating to high frequency induction heating apparatus
Inventor: AINSCOW PHILIP WATSON
IPC: H05B6/06
Filed: 1958-02-03
Abstract: 861,628. Actuation of switches. GENERAL ELECTRIC CO. Ltd. Feb. 3, 1959 [Feb. 3, 1958], No. 3461/58. Class 38 (5). [Also in Groups XI and XXXV] High-frequency induction heating apparatus in which power is fed to one or other of two work-stations comprises a transformer having a primary winding arranged to be fed with power and first and second secondary windings associated, respectively, with said work stations, and means for moving the primary winding between first and second positions in which it is coupled to said first and second secondary windings, respectively. The arrangement is such that an operator can assemble and load a work-piece at the inoperative station while another workpiece is being heat-treated at the other station. In the arrangement shown, a H.F. generator 1 supplies power to the primary winding 3 of a transformer 2 having two secondary windings 4 and 5 associated respectively with two workstations WS1 and WS2. The ends of the secondary windings 4 and 5 are connected to terminals 6 and 7. The primary winding 3 is moved into coupling relationship with secondary winding 4 or 5 by an electric motor 8 under the control of timing apparatus, and limit switches (not shown) are provided to prevent over-travel. The secondary winding 4 or 5 at the inoperative station is still very loosely coupled to the primary winding 3 and sparks may occur at the terminals 6 or 7 if these are accidentally shortcircuited by the operator. To prevent this a pivoted lever 13 having an insulated conductive wedge 14, 15 at each end is moved by rollers 18 mounted on arms 17 of a bracket 16 attached to the primary coil 3 to short-circuit the terminals 6 or 7 at the inoperative station. Alternatively an electromagnetically-operated short-circuiting device may be used. The secondary windings 4 and 5 may have different numbers of turns and may be of different diameters.

Title: Improvements in or relating to reversing mechanism for looms for weaving
IPC: D03D51/00
Filed: 1926-02-13
Abstract: 253,035. Hollingworth, E.9 (Crompton & Knowles Loom Works). Feb. 13, 1926. Addition to 251,877. Driving, reversing, starting, and stopping arrangements. -In carpet-loom driving mechanism as described in the parent Specification, means are provided to warn the operator, when in reverse, as to the proper time for stopping the loom. The lever 38 which, when in reversing position, masks the shipper-lever notch in the slotted guide-plate 28, is mounted on a shaft 37. A two-armed lever 46, 47 on the other end of the shaft 37 is rotatably supported by the spindle 50 of the motor-switch 43 and actuates the switch-lever 44, Fig. 2, through a lost-motion connection when the lever 38 is shifted. The shipper-lever 24, when shifted to the right, Fig. 1, against a spring 26, acts through connections 23, 21 to close a friction-clutch 17, 18, so that the shaft 16 is driven from the motor 13. The shaft 16 drives a lay-operating shaft 32, which in turn drives a picking-shaft 35 through suitable gearing; e.g. a three-to-one gearing for a threeshot loom. To an arm of the lever 38 is pivoted a rod 42 having a forked cam-end 52 embracing a shaft 54 between an arm 55 thereon and a bearing 53. The shaft 54 is slidably and rotatably mounted in the bearings 53 and is urged to the right, Fig. 2, by a spring 57. As shown in Fig. 1, the mechanism is in forward running position and the shaft 54 is held to the left, Fig. 2, by the upper portion of the cam 52, so that an arm 58 on the shaft is out of the path of pins 59 on the gear-wheel 34 on the shaft 35. When the loom is stopped and the lever 38 is thrown over, the arm 47 coacts with the pin 45 on the switch-lever 44 to reverse the motor; the lost-motion connection acts to compensate for inaccuracy in the switch-setting. At the same time, the rod 42 is raised, so that the cam 52 allows the shaft 54 to shift the arm 58 into the path of the pins 59. When the shipper-lever 24 is held in the dotted starting-position shown, Fig. 1, the pins 59 shift the arm 58 once for each reciprocation of the lay, and, in doing so, oscillate the arm 55 on the shaft 54 to move the shipper-lever towards stopping position; if the warning is not heeded, the loom will be positively stopped. A number of reverse motions may be given to the loom with a single setting of the reverse lever.

Filed: 1925-02-14
Abstract: 241,079. Frommer, R. von. Feb. 14, 1925. Counter-scales and the like.-A weighing-scale of the double parallelogram type having inverted U-shaped girders carrying notched or V-bearings adapted to rest on the end knife-edges of the scale beam is characterized by the fact that the girders are formed of stamped or pressed sheet metal, and each constitutes one element of a cross-shaped pan holder, the other element of which is constituted by a sheet metal strip secured to the girder. The side members 1 of the frame are pressed from sheet iron and are united by transverse rods 2 and by a bridgepiece 21. The fulcrum bearings 5 for the beam 7 are secured to plates 3 which are retained against the outsides of the side members 1 by the riveted ends of the bridge-piece 21 and one of the rods 2. The pan support 11 at each end of the beam is of inverted U-shape as shown in Fig. 2, and is secured to a depending leg 22 cranked as shown in Fig. 1 to avoid the knifeedged bar 8. Stop plates 13 and a sheet-metal cross-piece 15 are secured to the pan support to accommodate the scale pan. Indicating pointers 19 are formed on the cross-bars 15. Integral w ith or attached to each depending leg 22 of the pan supports are two contacting plates 24, 25 cut away so as to form aligned knife-edges upon which the stay 23, Fig. 1, rests. The centre of the stay is provided with notches which engage downturned tongues pressed out of the bridge-piece 21. Apertures 4 are cut in the plates 3 to receive inscription plates.

[Also in Division G3] A bank 11 of manually actuated valves has an end casting 10 providing a common inlet 12 for all the valves, this casting also housing a main relief valve 19 urged to closed position by spring 17 and opened when pilot valve 32 opens to admit fluid to chambers 37, 38. These chambers communicate with common exhaust duct 51 via the annular clearance between pin 34 and hole 33 and duct 40. As shown, each of the valves in the bank is in its neutral position allowing rod 18 to unseat valve 19 to connect the inlet to exhaust through port 39. When any of the valves are moved to an operative position, cam means (not shown) moves rod 18 to allow the valve 19 to seal and function as a relief valve for fluid flowing to the bank via passage 43.
