Patent GB-822482-A (GB)
Title: Improvements in the manufacture of electric power cables
Inventor: PILPEL NEITON
IPC: H01B13/30
Filed: 1955-07-14
Abstract: 822,482. Impregnating for electric insulation. BRITISH INSULATED CALLENDERS CABLES Ltd. Oct. 12, 1956 [July 14, 1955], No. 20452/55. Class 140. In a method of making an impregnated paper insulated power cable comprising the steps of preparing an impregnating composition by mixing an organic polymer such as polyisobutylene with a mineral oil to thicken the oil, drying and degassing the impregnating composition, and impregnating the paper with it, the impregnating composition is, during one of these steps, subjected to ultrasonic vibrations to bring about a temporary reduction in its viscosity. The composition may be subjected intermittently, e.g. for periods of one or two seconds, to vibrations in the frequency range of 16-250 kc/s. As shown, a paper insulated cable coiled on a drum 2 is placed in an impregnating tank 3 provided with a hollow, liquidtight core 5, open at its lower end, which acts as a mounting for magneto-strictive ultrasonic generators 6, connected by a cable 7 to a power supply 8. The pipe line for circulating the impregnating composition from a storage tank 9 to the impregnating tank 3 includes a chamber 10 in which are mounted bowl-shaped piezoelectric ultrasonic generators 11 which produce a focused beam of energy. The pipes and tank are heated and/or lagged to maintain the composition in a heated condition. In an alternative form of impregnating tank, ultrasonic generators are mounted in the outer cylindrical wall of the tank in addition to those mounted in the core. The process enables higher viscosity compositions, or higher density paper, to be used. Specification 581,830 is referred to.

Abstract: 1,274,622. Continuous multiple chamber furnaces. SIGRI ELEKTROGRAPHIT G.m.b.H. 19 April, 1971 [21 Feb., 1970; 5 March- 1970], No. 20506/71. Heading F4B. In the firing of shaped carbon bodies in a continuous multiple chamber furnace with twenty treatment chambers fired in turn, flue gases from chamber 1 presently being fired are cooled in chamber 6 by water sprays 26 when the temperature indicated by a thermocouple 28 rises unduly rapidly. The gases are being extracted from chamber 12 by a conduit 21 opening into a main flue 22. Chamber 16 is open to the air which after cooling the treated bodies in the remaining chambers passes from chamber 20 to chamber 1 for use as combustion air. In a modification (Fig. 1) cooling air is supplied to chamber 6 through nitrogen, carbon dioxide or other inert gas or vapour could be used. The evolution of gases or over-vigorous combustion of these gases are thus controlled. More than one chamber may be fired or cooled at one time.

Title: Improvements in or relating to chip-board manufacture
IPC: B27N3/14
Filed: 1959-06-16
Abstract: An apparatus for use in the manufacture of chipboards from chips of wood or other suitable material coated with an adhesive, comprises a device 1 for distributing the chips as a fleece on a carrier 6, and a press 7 for pressing a length of <PICT:0856795/IV(a)/1> the fleece. During pressing, the carrier 6, which may be an p  endless belt, is stationary and the device moves along it, away from the press 7, over a distance equal to the length of fleece which the press can accommodate.  On completion of pressing, the press opens and the device 1, now inoperative, moves back to its original position whilst the carrier 6 conveys the newly-formed length of fleece to the press, the required length being sawn off. The chip distributing device is conveniently supported by wheels on a rail 9 and is preferably of the type using air jets from a chest 5 to form a fleece comprising outer layers of fine chips surmounting a core of coarse chips.

Abstract: 927,930. Data storage apparatus. MONROE CALCULATING MACHINE CO. June 16, 1959 [June 25, 1958], No. 20589/59. Class 106 (1). A magnetic drum store has a number of words stored in a single track, the words being interlaced under control of sets of timing signals one of which corresponds to a recirculating word normally recorded in each word sector. As shown, three words are interlaced in each sector, the words being read out in line 14 and each bit entered in flip-flop 18 (p pulses occur at each bit time). Timing pulses P 0  correspond to the bits of the recirculating word in 18, so that this word is normally passed unchanged through adder 30 and rewritten in the next sector; by energizing line 42 or 44 one of the two words also stored in a given sector may be passed via flip-flops 46 and 50 (re-timing them to P 0 ) to the adder so that it can be placed in the recirculating register (cleared previously), or the recirculating word can be written in the P 1  or P 2  position also by energizing 54 and 60 or 62.

[Also in Division G1] In order to measure the difference between the depths of modulation of two different frequency components of a modulated carrier wave, the detected 12, Fig. 1, carrier namely where # 1  and # 2  correspond to the two modulation frequencies and are for example 90 c./s. and 150 c./s. when the system is applied to radio navigation, is multiplied 13, 14 by locally generated 15, 19 signals sin # 1 t and sin # 2 t, respectively, the D.C. components of the resulting signals, namely ¢Am and ¢An are extracted by low pass filters 24, 25 and their difference is displayed on a centre zero meter 26. In order to ensure that the local oscillators 15, 19 are locked to the two modulation signals, the detected carrier is also multiplied 17, 21 by 90 degree phase-shifted 16, 20 signals cos # 1 t and cos # 2 t, and the resulting D.C. components, which should be zero if the local oscillators are correctly locked, are used to effect retroactive control of the oscillators. In the preferred embodiment each local oscillator, e.g. 15, Fig. 2, has a frequency of four times the required value. Its output is divided, by two series-connected trigger 16, to produce quadrature signals of the required frequency, which control gate-type multiplying circuits 13, 17 which either let the detected 12 carrier through 29 or block it and simultaneously earth 28 their outputs.

Title: Hydrogen cyanide-containing complexes and process of hydrogen cyanide addition employing the same
Filed: 1952-08-22
Abstract: The invention comprises N,N-dimethylacylamide-hydrogen cyanide molecular complexes having the formul  2HCN . HCON(CH3)2; 2HCN . CH3CON(CH3)2 and HCN . CH3CON (CH3)2.  These complexes are present in mixtures of hydrogen cyanide and the corresponding dimethylacylamide and may be used for the addition of hydrogen cyanide to unsaturated compounds.  The constituents of the complex may be added separately to the unsaturated compound.  Suitable unsaturated compounds are mono-olefinic or di-olefinic hydrocarbons; acetylene and acetylenic hydrocarbons and unsaturated aldehydes, ketones and quinones.  In particular, the complexes may be used for adding hydrogen cyanide to acetylenic compounds of general formula CH­CR in which R is hydrogen or an aliphatic hydrocarbon group having from 1 to 4 carbon atoms; and (b) aliphatic a ,b -unsaturated compounds in which there is attached to at least one of the unsaturated carbon atoms a nitrile group, a carbonyl group or an ethylenic group.  Suitable unsaturated compounds are, for example, vinylacetylene, acrylonitrile, 1 - cyanobutadiene-3, methyl vinyl ketone, mesityl oxide, acrolein, crotonaldehyde, acrylic acid, methyl methacrylate, maleic acid, diethyl fumarate, vinyl acetate, vinyl formate, butadiene, cyclopentadiene and hexadiene.  The process can be carried out at atmospheric or superatmospheric pressure, preferably with heating. If desired a catalyst, such as an inorganic alkali, metals, metallic salts, or organic amines and quaternary ammonium bases may be used. In the examples: (a) acrylonitrile and hydrocyanic acid are added to a mixture of dimethylformamide and triethylamine and the mixture on distillation gives succinonitrile.  Similarly acrylonitrile may be obtained from acetylene and hydrocyanic acid; 1-cyano-1,3-butadiene and 2,3-dicyano-2-butadiene may be obtained from vinyl acetylene and hydrocyanic acid; lactonitrile acetate may be obtained from vinyl acetate and hydrocyanic acid, 1-cyano-cyclohexyl acetate may be obtained from 1-cyclohexenyl acetate and hydrocyanic acid; ethyl levulinonitrile may be obtained from methyl vinyl ketone and hydrocyanic acid; and ethyl 2-cyano-acrylate may be obtained from ethyl propiolate and hydrocyanic acid.
