An apparatus for cladding a core 7 with a pair of strips 5 which are fed from opposite sides of the core comprises a pair of squeezing rolls 1 to solid phase bond the strips to the core after the core has been pulled through a skiving die 15 which removes any surface contamination. The core 7 is preferably aluminium or an alloy of aluminium and is guided by rollers 11 to the die 15. The die is positioned close to the nip space between the rolls 1, e.g. 0.3 inch, and immediately the core is cleaned it enters a chamber 21 containing an inert atmosphere, e.g. helium, or a reducing atmosphere. e.g. hydrogen. The strips 5 are preferably copper, and are fed to the nip space through a chamber 23, 25, 27 containing a reducing atmosphere. The strips are heated electrically to, for example 1600‹ C., by means of a contact 37 abutting each strip and a sliding contact on a guide roller 29. The strip cools before it reaches the nip. Alternatively the sliding contact may be on the roll 1 and the strip heated to a lower temperature. This heating of the copper strip removes any grease therefrom and the reducing atmosphere reduces any copper oxide on the surface of the strip.

Title: Improvements in or relating to systems for the distribution of programmes of music, speech or the like over line wires
IPC: H03F1/54
Filed: 1933-12-01
Abstract: 423,061. Distributing music &c. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, CLARK, F., and CHUBB, A. A., c/o General Electric Co., Stoke, Coventry. Dec. 1, 1933, No. 33742. [Class 40 (iv)] In a system for the distribution of radio programmes, &c., of the kind described in Specification 383,057 in which the amplifiers at the subsidiary distributing stations are controlled and supervised over the line from the main exchange, each line is capable of extension beyond a subsidiary station to further stations, control and supervisory signals being repeated to and from such stations at the first station. As shown, the line 2, 3 is connected through a transformer LC at the subsidiary station, Fig. 2, to the line 4, 5 leading to the extension station, Fig. 3. Operation of the key ST at the main station, Fig. 1, energizes relay M at the subsidiary station to switch on the mains. Current is then applied to the line 4, 5 through a transformer LE and rectifier to energize relay N to switch on the mains at the extension station. Relays SW, SX pull up when the amplifiers are in operative condition. Relay SX short-circuits a resistance HS, and a marginal relay R responds at the subsidiary station. With SW, R both up, a resistance HR is short-circuited, and the marginal indicator J operates at the main station. Failure of either of the amplifiers causes the resistance HR to be reinserted. The occurrence of a fault on the line 2, 3 operates the differential relays L, B, the former shunting out the indicator J and the latter shunting out M to switch off the amplifier at the subsidiary station. Relay N is deprived of current and switches off the amplifier at the extension station. The occurrence of a fault on the extension line 4, 5 operates the differential relays F, D, the former shunting out N and the latter, through the medium of E, reinserting the resistance HR to signal the main station and disconnecting the transformer LC from the line 2, 3. Additional extension lines may be tapped off the line 2, 3, and each extension line such as 4, 5, may be further extended to one or more stations. Specification 382,434, [Group XL], also is referred to.

Filed: 1954-11-23
Abstract: 774,555. Cathode ray tubes. GENERAL ELECTRIC CO. Nov. 23, 1954 [Dec. 14, 1953], No. 33942/54. Class 39(1). [Also in Group XL(b)] A light modulation system comprises an oblique optical grating 32 with alternate transparent and opaque-reflecting strips, a cathode ray tube having a plurality of electrical conductors 20 embedded in the end wall, a viscous liquid 18 such as oil on the outside surface of the end wall, means for directing a light beam through the grating on to the oil and means for scanning the conductors 20 with an intensity modulated cathode ray beam so as to set up a local electrostatic field between the conductors and on external electrode to distort the liquid locally so that light is reflected by the liquid through a transparent strip of the grating except where the oil is distorted where the light is reflected by the oil on to a reflecting strip of the grating and thence on to an image screen 26, the intensity of the light depending on the distortion of the liquid and hence on the intensity of the cathode ray beam. The conductors 20 are sealed through the tube end wall and conduct the charges laid down by the scanning beam modulated with video to oil film 18. A transverse electrostatic field is set up across the oil film 18 by means of biased conducting member 22. A beam of light is produced by arc lamp 24 and mirror 30, or by an incandescent filament, and is split up into a number of elementary light beams by opaque strips 34 mounted on glass plate 36. In the absence of a video signal, light from 24 is reflected by the polished ends of conductors 20 or by oil film 18, but when the electron beam is modulated by video the oil film 18 is deformed depending on the difference between the charges collected by conductors 20 and light is reflected to strike strips 34 which are coated with light reflecting material, so that a visable image can be built up on screen 26. The oil film has the characteristics described in Specification 561,926 [Group XL] and may be admixed for this purpose with a viscosity increasing agent and with an electrical conductivity increasing agent.

Title: Improvements in and relating to pulse synchronisation
IPC: H03K5/156
Filed: 1969-07-08
Abstract: 1279682 Multiplying and dividing circuits CHANDLER EVANS Inc 8 July 1969 [16 July 1968] 34444/69 Heading G4G An analogue computing circuit comprises a a source of reference pulses and a source of information signals, these signals being combined in circuit 10 to provide output pulses synchronized with the reference pulses and of width dependent upon the information signals, these signals being further width-modulated in a second circuit 12. As shown, the information pulses have about three times the repetition rate of the reference (clock) pulses. The input pulses are fed to a memory trigger circuit 14 and a NOR gate 22 whilst the clock pulses are fed to the NOR gate 22 and to a trigger circuit 18. The NOR gate inverts the clock pulses (signal B) and trigger 14 produces spikes (signal A) synchronized with the leading edges of the input pulses. Signals A and B are fed to a single-bit memory circuit 26 comprising NOR gates connected to form a set-reset flip-flop (see Fig. 4, not shown). Circuit 26 provides control signal C consisting of pulses having leading edges synchronized with the lagging edge of a clock pulse and lagging edges synchronized with the leading edge of "accepted" input pulses i.e. the next which are received after the lagging edges of an inverted clock pulse. The rest of circuit 10 comprises NOR gates N 2 , N 3 , memory trigger circuits 16, 18 and a further single-bit memory circuit 28 similar to memory circuit 26. The output consists of signal H having a repetition frequency equal to the clock signal and a pulse width equal to that of the input signal. This signal and signal C are fed (if necessary) via a level shifter 30 to switches S 1 , S 2  which control the charge and discharge of a capacitor C 1  from a source Vd. The amplitude and duration of signals I, J appearing respectively on the input and output electrodes of the capacitor are dependent upon both the width of the input pulse and the voltage Vd. The output J is added to a voltage level determined by an input Vc in a comparator 32. The resultant output pulses have a duration # given by where # 0  is the width of the input pulses.
