Title: Improvements relating to indicators or signs
IPC: G09F7/08
Filed: 1930-04-17
Abstract: 351,148. Signs ; changing signs. SIEMENS ELECTRIC LAMPS & SUPLIES, Ltd., Caxton House, Tothill Street, and CALVERT, F. L. L., 270, Kennington Park Road, Kennington, both in London. April 17, 1930, No. 12209. [Classes 3 (i) and 3 (ii).] In a sign in which characters or devices 15 are silhouetted against an illuminated background 13 and fixed in position by means which involve bringing a character or device on to or towards the face of the background 13, the front of the sign is provided with a rigid bar or bars or projecting strip or strips having moulded or beaded edges and the characters have correspondingly shaped spring clips 14 which can be sprung into engagement with the lower bars. In one form, the sign comprises a box 1 closed by a hinged or detachable door 2 and provided with a front of opal glass 13. The projecting strips are formed by turning up flanges 5, Fig. 3, the upper edges of which may be turned over, in which process a wire may be inserted in the edge. A securing bar 16 held in place by screws 17 or nuts and bolts may be provided to secure the clips 14, and the ends of the flanges 5 are connected by strips. In a modification the flanges 5 are formed as strips soldered to the front. When several rows of characters are required flanges such as 5 hold each row. In this case the opal glass may be in strips. The characters or devices may have gilded or otherwise coloured edges so as to impart a sheen thereto. In a further modification the box is dispensed with, the opal glass then depending for its illumination on daylight or lamps placed behind it. The characters may be trough-shaped in which case the background is illuminated by lamps placed inside the troughs. The flanges 5 may be replaced by two parallel bars or one central bar in which cases the characters are provided with spring clips other than at their edges. The lamps illuminating the background may be of different colours and may be flashed in and out in various successive combinations of colours.

Patent GB-418570-A (GB)
Title: Improvements in and relating to an arc switching device for alternating current switches, fuses or the like
IPC: H01H33/70
Filed: 1934-04-23
Abstract: 418,570. Fusible cut-outs. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. April 23, 1934, Nos. 12225 and 12226. Convention dates, April 28, 1933 and July 1, 1933. Drawings to Specification. [Class 38 (i).] A device for quenching A.C. arcs in fuses and of the kind comprising a quenching channel or conduit opening into spaces free of liquid, is so arranged that a given quantity of quenching liquid at the beginning of the circuit-opening process lies in a receptacle from which it is entirely ejected and driven into the channel during the opening process by a gaseous pressure medium admitted into the receptacle during said process. The liquid is ejected by operation of the compressed-gas valve by a release device carrying the excess current, but if the channel is lined with arc-resistant substance, the injection need not occur before the arc is drawn. The fuse wire may, alternatively, be so constituted as to have low melting-inertia thereby giving the flow of quenching liquid time to get established.
Patent GB-584511-A (GB)
Title: Improvements in and relating to knitting machines
IPC: D04B15/64
Filed: 1944-06-28
Abstract: 584,511. Knitting-machines. COTTON, Ltd., W., WILDERS, G., and LYNAM, J. E. June 28, 1944, No. 12335. [Class 74 (ii)] [Also in Group XXVI] Hydraulic mechanism (see also Group XXVI) in a knitting-machine, particularly a straight bar machine, has means for collecting such hydraulic fluid as may leak therefrom and returning it to the hydraulic circuit. Fluid leaking past the gland 14 at each end of a hydraulic cylinder 11 collects in an annular space 30, whence it is conveyed by return pipes 31, 32, to a pump 34 which is mounted on the cylinder 11 and which returns the fluid to the system. A collector annulus is also provided at each end of the spindle of a valve 21 controlling a bye-pass 20 connecting the two ends of the cylinder: these collectors are connected by pipes 43, 44 to one of the return pipes. The cylinder 11 and piston 12 form a hydraulic coupling between the coulier mechanism and a carried rod 19. The cylinder is reciprocated by the coulier mechanism and the piston rod is connected to the carrier rod. Whilst the valve 21 remains closed, the piston is locked to and moves with the cylinder; but when, or slightly before, the rod 19 strikes its end stop, the valve 21 is opened by engagement of its plunger with one or other of cams 21a, 21b, and the piston 12 can remain stationary whilst the cylinder 11 continues to move, The spacing between the cams can be varied by stop mechanism to vary the point at which the valve is opened ; and the cams may be lowered at the end of the draw so that, as the cylinder moves in the reverse direction, the valve plunger falls off a step provided on each cam, instead of riding down the cam incline. Thus, the necessary lead is given to the carrier. The plunger 37 of the pump is pressed, through a compression spring 38, by a lever 39 rocked by two cams as the pump traverses to and fro. The pump is provided with inlet and outlet non-return valves. In a modification, Figs. 6 and 7, the spindle 21c of the valve is connected to a lever 45 which is rocked from the "closed" to the "open" position by the appropriate one of an inner pair of ramps 48, the adjacent one of an outer pair of ramps 49 swinging out of the way against the action of its spring 50. On the return stroke, that outer ramp 49 moves the lever 45 to the "closed" position and the inner ramp 48 yields. The spacing between the ramps 48. 49 may be adjusted, to vary the lead, by means such as slots 52 and bolts 53, or each device 48, 49. may be connected to speed regulating or control apparatus for adjusting the spacing in conformity with machine speed: for example, the connection may extend to the speed-control quadrant 12 of Specification 548, 713. Specifications 565,240 and 565,268 also are referred to.

Title: Frequency voltage converters
IPC: G01R23/02
Filed: 1974-03-20
Abstract: 1462105 Frequency detectors; transistor switches VDO ADOLF SCHINDLING AG 20 March 1974 [6 April 1973] 12445/74 Headings H3A and H3T A frequency detector in which input pulses are converted into further pulses by charging a capacitor 9 through a first switch 8 and discharging it through a second switch 13, is characterized by the latter switch being an FET. The rising edge of an input pulse 2 turns off transistor 16 allowing capacitor 18 to discharge until the potential across capacitor 18 falls sufficiently for transistor 19 to cut off to turn off transistor 8 and disconnect capacitor 9 from supply +U B . As the potential across capacitor 18 falls still further transistor 20 turns off to turn on FET 13. Capacitor 9 now discharges to produce an output pulse on line 3. When the trailing edge of input pulse 2 arrives, transistor 16 is again turned on and capacitor 18 commences to charge. Transistor 20 is turned on to turn off FET 13 and as the voltage across capacitor 18 rises further, transistor 19 is turned on to turn on transistor 8. Capacitor 9 now charges to produce a further output pulse on line 3. The output pulses are then fed to integrator 4.

Filed: 1969-03-12
Abstract: 1,211,326. Electrostatic copying machines. COPYSTATICS MFG CORP. March 12, 1969 [April 30, 1968], No.12937/69. Heading G2H. A copying machine has a scanning window 22 and an exposure window 64, the original 12 to the copied being reciprocated past the scanning window by rollers 8, 17 and 7, 18, such that the original moves in the forward direction in synchronism with copy paper moving past the window 64 and in the reverse direction at a speed greater than that in the forward direction. Rollers 9, 16 feed the original 12 into the machine past a photo-cell 13 which causes energization of a clutch (K-6) Fig.3 (not shown), which drives copy paper rollers 35, 36 Fig.1. The rollers 35, 36 feed the copy paper past a cutting device 37, 38 which cut a length of copy paper corresponding to the length of the original. Rollers 35, 36 are stopped when the trailing edge of the original passes the photo-cell 13. Light from exposure lamps within reflector 25 is reflected by the original along the dotted line 27 through lens 28 and window 64 to expose copy sheets eletrostatically charged bycorona devices on opposite sides of the sheets. A shutter 31 is actuated externally to time the exposure. A selector dial 107 is adjusted to the required number of copies before or during machine operation. If multiple copies are required the leading edge of an original is sensed by a photo-cell 15 to cause repeated reversal of the original at a speed greater than the forward speed under the control of a circuit Fig.3 (not shown), which energizes forward and reverse clutches (K-7) and (K-8) respectively and prevents copying during reversal of the original. Latent images formed on the cut sheets are developed by passage through a trough 47 Fig.1 benealth a drum 48. The supply of developer in the trough 47 is replenished by a pump, not shown, from a tank 57 which can be pulled out from the machine by a handle 58. Wipers 51 and 52 engage the drum 48 and a squeeze roller 52 to prevent offsetting of a previous image. The developed image is dried by a lamp 59 around which circulating air is passed by a blower 24.
