[Also in Group XXXVI] A friction clutch 37 for coupling the control shafts 21, 22 of two or more potentiometers 10, 11 comprises a spring clip 37 fast with a contact rotor 25 fixed to the control shaft 22, the ends of which spring, in the disengaged position shown, lie in a groove 35 on the shaft 21, permitting individual control of each potentiometer, and are engaged by leftward movement of the shaft 21 whereupon the spring 37 frictionally engages the shaft 21 (Fig. 5, not shown) for dual control of the potentiometers. The end of the shaft 21 is formed with diametrically opposed flats and engages a complementary bore in the contact rotor 26, allowing relative axial movement between the shaft and rotor whilst securing them rotationally.. Each of the rotors 25, 26 carries a pair of contacts 28 which engage stationary resistances 24, and the terminal contacts 17 are connected to resilient arms 29 which bear against the rotors.

Title: Improvements in and connected with elongation gauges for use when testing materials in tension
IPC: G01B5/30
Filed: 1933-01-30
Abstract: 394,609. Gauges. HOUNSFIELD, L. H., 3, Durrington Park Road, Wimbledon, London. Jan. 30, 1933, No. 2826. [Class 106 (ii).] A gauge for measuring the percentage increase in gauge length of tensile test pieces after they have been pulled comprises a cradle or trough for carrying the test piece, abutments on the trough to engage the ends of the test piece, one being adjustable to a fixed position and the other being movable with an index lever travelling over a scale, and means for adjusting the relative positions of the trough and lever in accordance with the gauge length of the test piece. As shown, a trough 1 carries abutments 12, 18 having vertical faces to engage a test piece. The abutment 18 is adjustably secured to the trough by a screw 19, nut 21, and spring 22, the screw extending through a slot 20 in the trough. The abutment 12 is slidable on the trough and is frictionally held by a plate 13 extending over its sides; it carries screwed pins 15, 16 respectively engaging an index lever 9 and carrying a spring 17 engaging the lever. The trough is secured to a saddle 2, adjustable on a slide 4, and having a cover 3 and fixing screw 5. The slide 4 carries the pivot 8 for the lever 9, and also a scale 10, and is graduated so that it may be set, relatively to index marks 6 on the saddle 2, in accordance with the known gauge length of the test-piece, or in accordance with a distinguishing number applied to the test-piece and varying with such length. The abutments are set up so that, when the test piece, before being pulled, is between them, the reading on the scale 10 is zero. After the piece has been pulled, it, or the assembled piece if it has been broken, is again placed between the abutments, the necessary adjustment being applied only to the abutment 12; the percentage extension is then read from the scale 10.

Abstract: 372,833. Sewing-machines. BREGMAN, M., 37A, Camp Road, and MOLLAN, F. H., 5, Camp Road, Leeds. Sept. 2, 1931, No. 2988. [Class 112.] Blind-stitching machines; loop stitching.- A curved needle 3 forms a blind stitch, Figs. XII and XIII, with the aid of a looper 1 carrying a looper thread, and a loop spreader 2. The needle-carrier 4 is actuated by an eccentric causing the needle to enter the work without penetrating to the rear face thereof. The loop left by the needle is entered by the looper 1 which lays a loop inside the needle loop. This looper loop is then held by a loop spreader 2 while the needle penetrates it on its return work penetrating stroke, Fig. VII. This produces the stitch as shown in which the needle and looper thread loops mutually lock each other against unravelling. Folding devices.-The work is held on a plate 13 with an up-curved end, the edge of the work being folded over a plate 14. The depth of the hem is regulated either by various distance pieces 23, Fig. III, or by mounting the plate 14 on an arm 15 working over an arc 17 and carrying a plunger 19 to fix it in adjusted position.

Title: Improvements in or relating to power supply circuits for electron discharge devices
IPC: H03F1/54
Filed: 1955-02-02
Abstract: 764,273. Valve circuits. WESTERN ELECTRIC CO., Inc. Feb. 2, 1955 [Feb. 8, 1954], No. 3080/55. Class 40(6) The heaters of a plurality of valves are fed from a common source through a network of voltage dropping resistors so arranged that each heater is fed from an effective source whose impedance is matched to the nominal value of the heater impedance. The arrangement reduces the effect of variations of heater resistance on heater power. In one embodiment each heater is fed through an individual series resistoi R1-Rn and a common resistor CR. In another embodiment, Fig. 2 (not shown) the common resistor is omitted, the correct heater voltage being obtained by shunting each heater with an individual shunt resistor. Formulae are given in the Specification for calculating the values of the resistors concerned. In the illustrated embodiment, the value of the common resistor CR may be reduced somewhat from the optimum value, the resistors R1- Rn being correspondingly increased; in this way variations in the heater power of one valve due to variations in the heater resistances of other of the valves may be reduced.

The exposed surface of a PN junction in a semi-conductor device is etched and then exposed to the vapour formed above a liquid consisting of nitric acid and hydrofluoric acid until a thin layer is formed over the exposed portion of the junction the thickness of the layer being such that it exhibits the colour of a thin plate. In the described embodiment a P-type silicon disc has an ohmic electrode comprising a gold foil disc containing 0.3% boron alloyed to one face and a PN junction formed by a gold foil disc containing 0.5% antimony alloyed to the other face, the alloying taking place whilst the assembly of discs is embedded under pressure in an inert powder. The PN junction is then etched, e.g. on an etching centrifuge in which the disc is rotated about its axis of symmetry whilst it is sprayed with etchant, after which the device is rinsed in water and exposed to the vapour of a nitric and hydrofluoric acid mixture. If desired the rectifier element may then be tempered for 24 hours at 200-300� C. then again etched and exposed to the vapour.
