Title: Improvements in or relating to key cutters
IPC: B23Q3/00
Filed: 1963-01-11
Abstract: 1,029,881. Key-cutting. INDEPENDENT LOCK CO. Jan. 11, 1963 [March 27, 1962], No. 1384/63. Headings B3B and B3K. A key-cutting, milling or filing machine, which may be associated with a vending machine, comprises automatically-operating clamps for holding a key 14 and a blank 15 during cutting and means for moving a pivotally mounted cutter and tracer support 30, 50 along the blank. The cutter support comprises a carriage 30 sliding on a rod 18 and a flange 17 by means of feet 34, 35 and a pivoting box-member 50 having recesses 54, 55 engaging trunnions 37, 38. The member 50 carries a motor M driving the cutter 59 through a belt 62. The weight of the motor, which may be supplemented by springs, holds the tracer 63 on the pattern key. The motor M, through a flexible shaft 75, also rotates a shaft 72 at a speed of 2 revs./min. The shaft carries cams 122 which in conjunction with springs 104 and rods 101, oscillate jaws 100 to hold the pattern and blank in holders 12, Fig. 7 (not shown), and cams 117, which in conjunction with springs 114 and rods 111, operate wedges 110 to force a spring-operated jaw 82 against a key 14. The cams so act that, when the keys are clamped the initial-positioning jaws 100 are lifted clear. A further cam 131 on the shaft 72 moves a rod 39 to traverse the cutter and tracer over the keys. A rough cut is made on the forward stroke and a finishing cut ensues on the return stroke. The machine is started when switches are actuated by rods 101 when both keys are pushed fully home. The motor M is stopped automatically in its rear position. In a modification, both clamps are operated by a single cam.

Title: Improvements in terminal arrangements for electric cables
IPC: G01L19/08
Filed: 1934-01-15
Abstract: 431,864. Pressure gauges. ENFIELD CABLE WORKS, Ltd., and BOWDEN, E., Lincoln House, High Holborn, and CHAPLIN, S., 19, Clare Lawn Avenue, East Sheen, both in London. Jan. 15, 1934, No. 1428. [Class 106 (ii)] [See also Group XXXVI] A cable end-bell, particularly of the oilfilled type, is provided with a device which is adapted to give a permanent indication when the pressure within the end-bell has risen to a predetermined value, regardless of subsequent pressure variations. The device may consist of a pressure responsive element operating through a one-way or lost motion connection to impart movement to an indicator which on being moved past a predetermined point is prevented, by friction, gravity, a spring, or a ratchet, from returning towards its original position. In the form shown, the device comprises a pressure-gauge tube 1 of the bent oval type enclosed in a case 2, Fig. 2, which is adapted to be secured by a screwed plug 3 to the end-bell. The pressure-gauge tube 1 communicates with the interior of the end-bell through a passage 5 in the plug 3. The closed end of the tube 1 is connected by a link 6 to a toothed quadrant 7, the teeth of which mesh with a pinion 8 mounted centrally in the case 2 in bearings 9, so that outward radial movement of the end of the tube 1, due to increase in pressure, causes the pinion 8 to rotate in a clockwise direction. An axle 21, which rotates with the pinion 8, carries an arm 10 adapted to rotate an indicating disc 12, Fig. 1, which is freely mounted on the axle and carries a weight 13 mounted in a calibrated slot 15. Rotation of the disc is effected by a pin 11 which projects from the disc and rests on the arm 10. Upon the pressure within the end-bell rising sufficiently to rotate the weight 13 past the vertical plane the axle 21-depending upon the position of the weight in the slot 15-the disc continues its rotation under the action of gravity on the weight 13 until a pin 20 on the disc strikes the edge of a semicircular disc 14 which covers the lower half of the device. Subsequent fall of pressure does not return the disc 12 as the pin 11 is now disengaged by the arm 10. The disc 12 may comprise two distinctly coloured halves. To increase the range of adjustment of the device, the pin 11 may be inserted in either of two positions 16, 17. The device may be adapted to function as a normal pressure-gauge by extending the axle 21 and providing it with a pointer which moves over a scale on the semicircular disc 14.

Abstract: 1305802 Semi-conductor devices GENERAL ELECTRIC CO 21 Jan 1970 [21 Jan 1969] 1461/70 Heading H1K [Also in Division H4] An information storage device comprises a conductor - insulator - semiconductor (CIS) capacitor 32, Fig. 3, charged originally to a predetermined voltage such as to produce a depletion region with a surface inversion layer, the change in the voltage resulting from the discharging effect of minority carriers generated in the semiconductor in response to an information-bearing signal and swept through the depletion region into the inversion layer of the capacitor 32 being measured to provide the read-out. In the preferred embodiment the read-out arrangement comprises an MOS transistor whose gate electrode 34 is part of an extension 33 of the conducting layer of the capacitor 32. The depletion region area 37 of the capacitor and the channel region of the MOS transistor may both be defined by relatively thin portions of a SiO 2  layer 30, the remainder of the layer 30 being thick enough to prevent a depletion region being formed beneath the other parts of the conducting layer. Suitable semiconductor materials include CdS or InSb, while the conducting layer may be of a metal, tin oxide or doped Si. In an embodiment particularly suited to large-area capacitors the conducting layer of the capacitor comprises a series of spaced highly conductive Mo contacts connected together by a common less conductive material. Minority carriers to be stored may be generated by means of a pn-junction or a point contact, but preferably they are proproduced by absorption of suitable electromagnetic radiation incident upon the body through the conducting and insulating layers. Fig. 5 shows part of a Si integrated array of light-sensitive CIS capacitors 50 arranged in rows and columns, the capacitors being initially charged to a predetermined level using setreset liners 52 which charge each capacitor 50 via a two-gate IGFET 56, the gates of which are connected to column and row address lines 54, 55. After irradiation with a light pattern the capacitors are sequentially addressed again while the set-reset lines 52 are at ground potential, and the voltage now across each capacitor 50 is determined by the current through a three-gate IGFET 57, one of the gates of which comprises part of the extension 60 of the capacitor conductor layer 51 linking the capacitor 50 to the drain 59 of the IGFET 56, the other two gates being connected again to the row and column address lines 54, 55.
