Title: Improvements in electric cables
IPC: H01B9/06
Filed: 1930-03-11
Abstract: 347,819. Cables. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd. and BRAZIER, L. G., Hamilton House, Victoria Embankment, London. March 11, 1930, No. 7923. [Class 36.] In order to compensate for the expansion and contraction of the oil in an impregnated cable, cushions of gas enclosed in containers, to which the impregnating oil has access, are provided throughout the length of the cable, the entrance passages of the containers being so arranged that the oil always serves as a seal to prevent the escape of gas. In the embodiment shown, the hollow conductor 3 of a paper-insulated cable 1 is provided with a series of containers 4 adapted to be filled partly with impregnating oil and partly with a gas. The oil in the containers 4 communicates with the impregnating oil inside the hollow conductor 3 by internally projecting tubes 6 formed on the ends 5 of the containers. In order to prevent escape of gas from a container, the volume of gas is such that under working conditions it always occupies less than half the volume of its container, so that the inner end of the tube 6, which extends to the centre of the container remains always below the level 7 of the oil in the container. In order to fill the containers initially with gas and oil, they may be exhausted and the desired volume of gas allowed to enter, the containers then being placed under oil to complete their filling. The containers may be inserted in the cable one at a time or may be pulled through in the form of a chain. In order to prevent the solution of the gas in a container in the oil with which it is in contact, a gas of low solubility may be employed or the oil may be saturated with the gas at the average working pressure. In a multi-core cable the containers may be disposed in the filler spaces between the cores.

Abstract: Coating compositions comprise either (a) the homopolymer of a bicyclic terpene acrylic ester, or of a bicyclic terpene acrylamide or (b) an interpolymer of a monomer from (a) above and one or more other ethylenically unsaturated monomers.  The terpene acrylic compound may be derived from a terpene such as camphene, beta-pinene alpha-fenchene, beta-fenchene, iso-bornene and sabinene, and the acrylic ester or amide component may contain an alpha substituent such as lower alkyl, halolower alkyl, hydroxy-lower alkyl and halogen groups.  Monomers which can be copolymerized with the terpenic monomers include unsaturated acids and their anhydrides, esters and nitriles, esters of unsaturated alcohols, chloro-alkenes, styrene and its derivatives, dienes and chloro-dienes, vinyl-heterocyclic compounds and vinyl ketones. Many are specified.  The weight ratio of terpenic monomer to comonomers is between 20:1 and 1:4. Examples illustrate the polymerization of N-isobornylacrylamide in ethanol using benzoyl peroxide catalyst, and with the same catalyst but in toluene (a) isobornyl acrylate, (b) isobornyl a -chloromethyl-acrylate, (c) isobornyl acrylate and octyl acrylate, (d) isobornyl acrylate and styrene and (e) isobornyl acrylate and vinylidene chloride.  For coating, the polymers are dissolved in xylene or toluene. The product of (a) is obtained in the form of a foamed mass, which is ground into finely divided form.ALSO:The surface characteristics of a polyolefin material comprises applying to the surface either (a) the homopolymer of a bicyclic terpene acrylic ester, or of a bicyclic terpene acrylamide or (b) an interpolymer of a monomer from (a) above and one or more other ethylenically unsaturated monomers.  The terpene may be camphene, beta-pinene alphafenchene, beta-fenchene, iso-bornene and sabinene. The acrylic compound used to form the terpene monomers may be acrylic acid or may contain an alpha substituent such as lower alkyl, halo-lower alkyl, hydroxy-lower alkyl and halogen groups.  Numerous specific compounds are specified.  Monomers which can be co-polymerized with the terpene acrylate include vinyl, vinylidene or vinylene monomers.  Many are specified.  The ratio of terpene acrylate monomer to co-monomers is between 20:1 and 1:4.  One or more co-monomers may be used.  The application may be by dipping, spraying or spreading with a knife or roller. The coating may be dried at an elevated temperature after application and many commonly used coating systems may be coated over the dried undercoat.  Moulded or extruded objects, films, fibres and non-woven fabrics may be so-coated.  The top-coat may be of nitro-cellulose lacquers, acrylic lacquers, cellulose acetate-butyrate lacquers, alkyd amine lacquers, phenolic and urea compositions.  The polyolefin base may be polyethylene or polypropylene.  Printing inks or pigments may be incorporated into the coatings.  The polyolefin surface may be treated before coating by corona discharge.

Title: Circuit arrangement for linear voltage-frequency or current-frequency  conversion
IPC: H03K7/06
Filed: 1972-02-22
Abstract: 1379856 Pulse modulation circuits; sawtooth wave generators AKADEMIE DER WISSENSCHAFTEN DER DDR 22 Feb 1972 8126/72 Headings H4L and H3T In a linear voltage-to-frequency converter, Fig. 2, the input voltage S 2  charges a capacitor 2 rapidly via a switch 3 (which may be a semiconductor device) the capacitor being connected via an adjustable resistance R to the base of a transistor T1. The collector voltage S 1  is combined with the voltage S 2  and the resulting output S 3  is supplied to a comparator 5. When the voltage S 3  falls below the threshold value of comparator 5 the switch 3 is opened and the capacitor discharges non-linearly via resistance R. When the voltage S 3  exceeds the threshold value, the switch 3 is closed to cause recharging of the capacitor 2. In a modification, Fig. 3a, the capacitor 2 is charged by the input voltage S 2  via a diode D controlled by a transistor T1, a tunnel diode Tu with resistor R 2  acting as a comparator and the output pulses being taken from terminals 6, a pulse being emitted each time the voltage across the tunnel diode exceeds a predetermined value. In operation, if the current through transistor T1 falls below apredetermined level the working point of the tunnel diode reaches the peak of its characteristic and jumps to its high voltage state when the current continues to fall. This renders diode D conductive and capacitor 2 is charged rapidly, the working point of the tunnel diode characteristic moving towards its valley. The resulting rise in the base voltage of transistor T1 causes the tunnel diode to jump to its low voltage state, diode D is blocked, capacitor 2 slowly discharges via the base-emitter path of T1 and the cycle is repeated.

Title: Improvements in or relating to electrically operated movement repeating systems
Inventor: ALLEN NIGEL ROBERT
IPC: G05D3/12
Filed: 1962-05-02
Abstract: 977,674. Correspondence control. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 3, 1963 [March 2, 1962], No. 8136/62. Heading G1N. A movement repeating system, for example a synchro system, of the type in which a receiver coil 10 is positioned by a servomotor 16 controlled by current collected from the receiver through relatively movable contacts, e.g. slip rings 13 and brushes 14, is provided with means for applying a bias sufficient to move the servomotor and means, dependent upon the flow of current through the relatively movable contacts, for opposing this bias by a second bias to permit normal operation of the system. Thus, if dirt prevents current flowing from the slip rings to the brushes the first bias energizes the servomotor, and the rotation of the receiver generally clears the dirt from the contacts so that normal operation is resumed. If the dirt remains the system hunts which acts as a warning, or may operate a warning system. As shown the first bias is the voltage drop across resistor R b  and under normal conditions this is opposed by the voltage drop across resistor R s . The equilibrium position of rotor 10 is, as a result, offset by a small angle, e.g. five minutes of arc, from correspondence with transmitter rotor 5. It is shown that the offset is constant so that compensation may be effected by providing a pointer on rotor 10 offset correspondingly. It is stated that means may be provided for stopping operation immediately the first bias ceases to be opposed.

[Also in Groups XXXI and XXXII] Means for counteracting the effect of centrifugal force on a motor vehicle having a pair of steerable wheels comprises a vane adjustable about a vertical axis in dependence upon steering adjustments of the wheels so as to lie at an angle to the direction of travel and thereby produce a centripetal force when travelling around a curve, the vane being arranged behind the centre of gravity of the vehicle. As shown in Fig. 2 the vehicle is provided with protuberances 17, 18 on which are mounted the vanes 19, 20 rotatable about vertical axes. The vanes are deflected in unison with the steering mechanism as shown in Fig. 7. The drop arm 51 of the steering mechanism can move a ported member 52 which co-operates with another ported member 53 which is connected to the vanes 19, 20 through links and a piston 54. The piston 54 is arranged in a cylinder 69 and pressure liquid from a pipe 61 can be introduced to either side of the piston on an initial movement of the member 52, such pressure moving the piston and the ported member 53, and the member 53 thus cuts off the supply of pressure liquid.

Abstract: 750,723. Refractometers. LKB-PRODUKTER FABRIKSAKTIEBOLAG. March 22, 1954 [April 18, 1953], No. 8323/54. Class 97 (1). An unknown and a reference substance are contained in compartments of a cell F having parallel outer walls and a dividing wall perpendicular to both. The cell is mounted on a turntable M and means is provided for measuring the deviation of a parallel light beam transmitted by the cell. In the form shown the slit D is illuminated by a source A with condenser B and filter C, the emergent light being collimated by a lens E before falling on the cell. The light transmitted by the cell falls on a fixed inclined reflector G and a reflector A by rotation of which the image formed by a lens I and observed by an eyepiece L may be aligned with a cross-hair K observed in an eyepiece L. A linkage for rotating the reflector H comprises a slidable bar X carrying a transverse block Z with a groove V engaged by a pin U at the end of an arm T coupled by 4: 1 reduction gearing S, R to the reflector. It is shown that this provides a linear relationship between the movement of the bar X and the difference between the refractive indices of the substances in the cell. The system I, K, L may be rotated instead of the reflector H. The gear ratio S: R is then required to be 1: 2. The sensitivity of the instrument is determined by rotation of the cell by the arm N moving over the scale P. The cell for a reference substance may be replaced by a glass block acting as the reference standard.
