Title: Improved Method of Producing Copper Wire
Inventor: NIGHTINGALE COLIN WALTER
IPC: C25D1/04
Filed: 1967-10-02
Abstract: 1,172,906. Continuously electro-forming copper. BRITISH COPPER REFINERS Ltd. Oct. 1 1968 [Oct.2, 1967], No.44697/67. Heading C7B. Copper rod for drawing down into wire is produced by continuously forming at least one elongated member, e.g. a single sheet 7 to be subsequently cut into a number of strips 15 by cutting rollers 14, a single strip or a plurality of separate strips, by electro-deposition on a cathode surface, e.g. formed by or carried on a rotating steel drum 3 or continuously moving belt, moving through a bath of electrolyte 2 adjacent to an anode or anodes 5 of partially refined (e.g. blister and/or scrap) copper, and continuously stripping the member from the cathode surface and passing it through the same or a different electrolyte bath adjacent to further anodes 10 of partially refined copper to build up its thickness to that required for drawing down. Preferably, the stripped member passes in a zig-zag path vertically downwards and upwards between each successive pair of a series of spaced vertical elongated anodes 10. Cutting into strips 15 may be effected as the sheet 7 passes from one part of the bath to another, or from one bath to another, or as it leaves the single or final bath. The knife edges of the cutting rollers 14 may be inclined to form strips 15 of hexagonal or near circular cross-section. At one or more intermediate stages, the member may pass out of the bath through an induction annealing chamber 12. The electrolyte may be introduced under pressure through a pipe 6 into the space 4 between the cathode surface and its associated anode (s) 5 in a direction opposite to that in which the surface is moving, e.g. drum 3 is rotated, to remove sludge. Forced circulation of electrolyte in the or each bath may also be effected. Some or all of the anodes 5, 10 may be in the form of perforated Ti containers filled with pieces of scrap copper, the containers preferably being surrounded by a porous covering of polyethylene, polypropylene or PVC. The Ti container may be annular to allow passage therethrough of a strip (Fig.4). Scrap copper may be replenished continuously during the process. The copper may be deposited on moving strips in such a way to build them up into a shape approximating to circular cross-section, by projecting the electrolyte preferentially on to selected parts of the moving strips, suitably shaping the effective surfaces of the further anodes, or by axially twisting the strips as they pass between the further anodes. Alternatively, two or more strips may be bonded together to form a rod by passing between pressure rolls or through a die.

Title: Improvements in or relating to o-type travelling wave tubes
IPC: H01J23/28
Filed: 1962-11-29
Abstract: 1,008,797. Travelling-wave tubes. C.S.F.- COMPAGNIE GENERALE DE TELEGRAPHIE SANS FILS. Nov. 29, 1962 [Dec. 7, 1961], No. 45128/62. Heading H1D. In an 0-type travelling-wave tube in which the electron gun has a single anode 4 maintained at a potential between that of the cathode 2 and the delay line 12, the first element 16 of the delay line directly adjacent the anode has such a form that the interaction space is incompletely shielded from the gun space, the electrostatic field between the envelope 1 and the anode 4 penetrating slightly through the passages 21, 22 between the interdigital line, shown, and the envelope. This is to prevent the movement of secondary electrons liberated at the first element of the delay line in a direction opposite to that of the beam and so giving rise to parasitic oscillations. In the backward wave tube shown, two ribbon beams 10, 11 are injected one on each side of the line. The first element 16 of the line extends through the envelope to couple out the energy produced. The line may also be coated, sand-blasted, milled electrolytically or spark eroded to reduce secondary emission.

Patent GB-469665-A (GB)
Abstract: 469,665. Actuating controllers. MORRISON & SONS, Ltd., A. E., MORRISON, A. E., and MORRISON, A. C. Jan. 29, 1936, No. 2710. [Class 38 (iii)] A controller comprises a switch or contact actuating member which is rendered operative by an operating member, and retarded by a delay action device, a yieldable connection being provided between the operating member and the actuating member, and the latter being associated with springs adapted to resist movement of the operating member and supplement the action of the delay action device. When only a small force is exerted on the operating member there is, in effect, a rigid connection with the actuating member so that the rate of switching is controlled by the operating member, but when greater force is applied, the connection yields and the actuating member moves at the maximum speed permitted by the springs and the delay action device. When small force is applied to a pedal 23, a rod 1, to which the pedal is coupled by tension springs 25 and a pin 26, is pulled down against the action of a compression spring 11 and retarding mechanism 3, and contacts 13, 14, mounted on the rod 1 pass over fixed contacts 17, thereby increasing the supply to a motor. The springs 25 are not strained by this operation, and the speed at which the contacts 13, 14, move may be varied by varying the pressure applied to the pedal. If greater force is applied to the pedal the springs 25 are strained, and the contacts 13, 14, are moved at the maximum rate permitted by the mechanism 3 and the spring 11. When the pedal is released the springs 25 contract, and then the spring 11 returns the contacts to the " off " position. The mechanism 3 may comprise a fan geared to the rod 1 with escapement mechanism permitting unhindered return movement of the rod 1. The spring 11 acts against a collar 12 on the rod 1 and the position of this collar may be adjusted.

Abstract: 1,134,925. Transistor pulse circuit; multiplex signalling. INTERNATIONAL STANDARD ELECTRIC CORP. 21 Oct., 1966 [22 Oct., 1965], No. 47146/66. Headings H3T, H4L and H4R. The high frequency signal is separated from mixed high and low frequency signals by applying the mixed signals to an amplifier which is selective to the low frequency signal and has negative feedback to balance out the low frequency signal, and the low frequency signal is separated from the mixture by subtracting the thus derived high frequency signal from the mixed signals. The mixed signal applied at p in Fig. 2 is a multiplex high frequency pulse code digital signal combined with a low frequency undesired signal or an audio order-wire signal in the frequency band 30 to 300 Hertz. It is applied to a differential amplifier Q8, Q9 having a constant current tail II and having components R21, C6 selected to make up the loss of high frequency components in the input line. Tho outputs of Q8 and Q9 are applied through emitter followers to peak detectors producing across C4 and C5 voltages which respectively follow the negative and positive peaks of the digital signal. The mid-value of these, which constitute the audio signal, is fed back in negative sense through Q15 to the input to balance out the audio signal and thus to provide the digital signal alone at P.C.M. The input signal to p is supplied from the line via an amplifier Q1, Q2, Q3, Fig. 1. The order wire signal is obtained by feeding the mixed signals from Q2 through Q4 to one input transistor Q6 of a differential amplifier and the digital signal from p to the other transistor Q6 so that the digital signal is balanced out. The resultant low frequency signal is supplied via amplifier Q7 and transformer T to the order wire OW.
