Abstract: 755,991. Taking up slack in electric cables. RUSHWORTH, D. July 6, 1955 [April 8, 1954], No. 10283/54. Class 78 (2). Apparatus for supplying power to a carriage A reciprocating on a track B, comprises a power supply cable D connected between a power supply point C and the carriage, a drum E for the cable and on which the cable is wound to pay out on both sides thereof, the drum being secured on an axle E<SP>1</SP> having wheels E<SP>2</SP>, and a wire rope F connected with the drum axle and adapted to move the drum towards the power supply point to wind up the cable when the carriage moves in the same direction. As shown, carriage A is driven to-and-fro along rails B, power being supplied thereto from supply point C by electric cable D wound on drum E carried on wheeled frame L. When carriage A moves to the right, the electric cable D is extended, the frame L following the carriage at half its speed; when carriage A moves to the left it causes frame L to likewise move to the left, the movement being communicated to the frame through arm K, endless rope H, pulley J and reel G carrying rope F connected to said frame. Alternatively, the rope F may be biased to the left by a counterweight.

Title: Improvements in or relating to methods of widening electric pulses and to apparatus for effecting such widening
IPC: H03K5/04
Filed: 1952-04-25
Abstract: 715,296. Pulse widening circuits. GENERAL ELECTRIC CO., Ltd., FISHER, S. F., and WARD, P. W. April 27, 1953 [April 25, 1952], No. 10478/52. Class 40 (6) A pulse widening circuit comprises a pentode valve to the control grid of which negative going input pulses are applied and which is capacity coupled to the screen grid the voltage of which is prevented from falling below a predetermined value, the anode being coupled to the control grid and positive going pulses being applied to the suppressor grid, widened output pulses being derived from the screen grid. The Figure shows a pulse widening circuit in which a pentode valve 1 has a feedback circuit via transformer 18 between anode and control grid and a rectifier 12 connected to the screen grid and thus preventing its voltage from falling below that applied to lead 13. Negative going input pulses to be widened are applied at 4 via rectifier 3 to the control grid of valve 1 thus reducing the current flow to the screen grid, so that its voltage rises and capacitor 7 is charged, the cathode, control and screen grids of the valve operating as a conventional Miller integrator circuit. When the input pulse terminates rectifier 3 becomes non- conducting and the voltage across capacitor 7 is held until the occurrence of a positive pulse applied at terminal 22, when the suppressor grid voltage rises and the resulting increase in anode current flow through transformer 18 causes the control grid voltage to rise, the effect being cumulative. Capacitor 7 is thus rapidly discharged until the screen grid voltage is held by rectifier 12. Thus each pulse applied at input 4 generates a positive going pulse at output 24 which is terminated by a pulse applied at terminal 22 so that by suitable phasing of these latter pulses a predetermined output pulse width is obtained. Rectifier 25 prevents ringing in the secondary winding of transformer 18 and capacitor 7 may be omitted if the control grid/screen grid interlectrode capacity is sufficiently large to effect the required widening of short pulses. Capacitor 23 and rectifier 14 may be omitted if the voltage applied to terminal 22 in the absence of a positive-going pulse is sufficiently negative.

A solid state electronic device with a negative resistance characteristic comprises an insulating film 80-1000  thick of a silicon or metal compound between two metal layers, the conductivity characteristic being produced by applying an increasing potential across the device in low atmospheric pressure conditions; an intermediate metal layer and second insulating layer may be provided to form a triode. The current through the device is believed to be space charge limited and only a small part is provided by tunnelling. The arrangement may be used to provide a cold cathode device. Fig. 1 shows a diode arrangement consisting of a glass substrate 11 with an aluminium layer 12 (2000 to 4000 A or thicker, e.g. 20 mils.) an aluminium oxide layer 14 (80 to 1000 ) and a gold layer 13 (40 to 300 ). The oxide layer may be produced by anodizing treatment of the aluminium layer using a fused melt of ammonium bisulphatepotassium bisulphate or alternatively, a solution of boric acid and borax in water. Contacts to the metal layers are provided and when assembled, the diode is subjected to electrical forming treatment in vacuo which results in a stabilized negative resistance characteristic. The electrodes may consist of two crossed strips with the oxide layer in the overlapping portion. In the triode embodiment, an additional aluminium. layer (100 to 600 ) and an aluminium oxide layer are provided between the first oxide and gold layers. The device may be operated under vacuum conditions and down to an operating temperature of 195 K. Other metals (except mercury) such as tantalum, titanium, zirconium may be used instead of aluminium and the insulating film may consist of magnesia, beryllia, silicon monoxide or alkali metal halide films in place of the aluminium oxide. Anodizing treatment of tantalum for example, to produce the oxide film may employ a solution of ammonium borate in ethylene glycol with water.
