Title: Improvements in or relating to circuit arrangements including charge storage tubes
Inventor: HOBBS DONALD SYDNEY
IPC: G01S13/524
Filed: 1958-01-31
Abstract: 882,799. Cathode-ray storage tubes. MULLARD Ltd. Nov. 11, 1958 [Jan. 31, 1958], No. 3361/58. Drawings to Specification. Class 39(1) [Also in Group XL(c)] In the storage tube circuit arrangement described in Specification 867,351 with reference to Figs. 3-5, means are provided for reducing negatively the cathode potential during the line fly-back time intervals in such manner that the beam is defocussed and positive charge is deposited uniformly over the elements of the storage surface scanned during such intervals, whereby storage elements which are negatively charged, due to a signal applied in an initial scan but not repeated in subsequent scans, are gradually restored to the unmodulated cathode potential during subsequent scans. Thus if the input signals are obtained from a radar receiver adapted to produce signals corresponding to echoes from both stationary and moving objects, output signals corresponding to stationary objects are obtained only during the first scan while in subsequent scans negative signals corresponding to the instantaneous positions of moving objects are obtained together with smaller positive signals corresponding to a number of previous positions of the moving objects. These positive signals may be separated out, inverted and then fed to the display system with the negative signals so that echoes due to moving objects appear with "tails" to indicate their direction of motion.

Title: Improvements in the demuriation of chloroethyl cholorobenzenes
IPC: C07C17/25
Filed: 1944-02-24
Abstract: Demuriation catalysts suitable for the conversion of chloroethylchlorobenzenes to dichloronuclearly substituted styrenes &c. comprise a mixture of a phosphate of an alkaline earth metal with the phosphate of a metal of variable valence (e.g., cobalt, chromium and manganese) deposited on a carrier of aluminium oxide or silicate, natural or synthetic, including kaolin, porcelain and florida earth. In examples: (1) barium, chromium and cobalt nitrates are boiled with aluminium oxide and phosphoric acid; (2) magnesium, cobalt and chromium nitrates are boiled with aluminium oxide and metaphosphoric acid.  The catalysts may be regenerated by heating in air or other oxygen bearing gas.ALSO:In the demuriation of chloroethyl chlorobenzenes to remove chlorine from the sidechain only, the demuriation is effected in the presence of a catalyst comprising an intimate mixture of a phosphate of an alkaline earth metal with the phosphate of a metal of variable valence especially of series 4 of the periodic table, e.g. cobalt, chromium, manganese, the molar ratio of the phosphate of the alkaline earth metal to the phosphate of the other metal being suitably about 2 to 1.  If two metals of variable valence are used, the phosphates may be present in the molar ratio of about 2 mols. of the alkaline earth metal phosphate to 1 mol. each of the phosphates of the metals of variable valence.  Suitable carriers for the catalysts are aluminium oxides and silicates, either natural or synthetic, including kaolin, porcelain and florida earth. Nitrogen or other inert gas may be used to carry the starting material over the catalyst.  In examples 1, 2 and 9, chloroethyldichlorobenzene (isomers mixture) is demuriated to nuclear dichlorosterene (isomers mixture) by passing it over a heated catalyst comprising barium, chromium and cobalt phosphates carried on an aluminium oxide known as "Alfrax" (Registered Trade Mark).  In examples 3 to 8 and 10, chloroethyldichlorobenzene (isomers mixture) is demuriated to nuclear dichlorostyrene (isomers mixture) by passing it over a heated catalyst comprising magnesium, cobalt and chromium phosphates and "Alfrax."  In example 10, the catalyst is regenerated 150 times, in operations extending over months, by heating it at 500 DEG  C.  The invention also covers the demuriation of chloroethyltrichlorobenzenes.  In the Specification as open to inspection under Sect. 91, the ambit of the invention there disclosed covers the demuriation of halogen-bearing organic compounds in general including aliphatic, cyclo-aliphatic and alkyl substituted aromatic compounds such as alkyl benzenes.  In this context are specified side chain halogenated ethyl benzene and homologues of ethyl benzene.  This subject-matter does not appear in the Specification as accepted.
Patent GB-1048914-A (GB)
Title: Modified copolymers of olefins and unsaturated carboxylic acids
IPC: C08F8/20
Filed: 1964-01-28
Abstract: Copolymers comprising at least 50 mole per cent of alpha-olefine units of the formula -RCH-CH2-, wherein R is hydrogen or a C1-C8 alkyl group, and 0.1 to 25 mole per cent of a -b -ethylenically unsaturated carboxylic acid halide units having 3 to 8 carbon atoms are prepared by reacting a corresponding olefine-unsaturated acid (or anhydride) copolymer with one or more halogenating agents.  The product may comprise unreacted acidic groupings. Halogenation is generally carried out in an organic solvent, e.g. carbon tetrachloride, perchloroethylene, trichloroethylene or "Freon" (Registered Trade Mark); a solvent may be absent if thionyl chloride vapour is used as halogenating agent.  Other suitable agents include carbonyl chloride, phosphorus trichloride and pentachloride and the equivalent bromine and fluorine compounds, e.g. phosphorus tribromide.  The initial, acidic copolymers are obtained by copolymerizing an appropriate a -olefine with a suitable acid monomer, e.g. acrylic acid, methacrylic acid, ethacrylic acid, itaconic acid, maleic acid, fumaric acid, monoesters of such dibasic acids, e.g. methyl hydrogen maleate or fumarate or ethyl hydrogen fumarate, and maleic anhydride.  The acid copolymers may also be obtained by copolymerizing the olefine with an unsaturated acid derivative, e.g. an ester, and converting the derivative to the free acid form.  Also, the acid monomer may be graft polymerized on to a preformed polyolefine forming, e.g., a methacrylic acid-polypropylene graft copolymer (other examples also listed).  The acid copolymer or graft copolymer may optionally comprise units of other monomers, e.g. methyl methacrylate, ethyl acrylate, acrylonitrile, styrene, vinyl methyl ether, vinyl acetate, vinyl alcohol, vinyl chloride, vinylidene chloride, vinyl fluoride and chlorotrifluoroethylene.  In one example, an ethylene-methacrylyl chloride copolymer (obtained by reacting the corresponding acid polymer with PCl5) is further reacted by heating with KHF2 to convert half the acid chloride groups to acid fluoride groups. In another example, a (chlorinated ethylene)-methacrylic acid copolymer is converted to the acid chloride form.  The acid halide copolymers are highly adhesive and are useful in forming laminates and coatings, and may be moulded into articles such as bottles.ALSO:Bottles blown from an ethylene-methacrylyl chloride copolymer are coated with a resin solution to decrease the permeability of the bottles to gases. Coating is effected by immersing the bottles in the resin solution, e.g. vinylidene chloride-acrylonitrile copolymer in methyl ethyl ketone, draining and heating in a vacuum oven to remove excess solvent.  Copper wire is extrusion coated with an ethylene-methocrylyl chloride copolymer.

Title: Improvements in machines usable as motors, pumps, couplings or the like
IPC: F04C2/36
Filed: 1960-02-02
Abstract: 882,262. Rotary engines and pumps. FISCHER, A. Feb. 2, 1960 [Feb. 11, 1959], No. 3713/60. Class 110 (2). [Also in Group XXIX] A liquid or gas motor, pump or the like comprises two coaxial relatively-rotatable cylindrical bodies 1, 3, Fig. 1, providing between them an annular channel, one of the bodies having one or more abutments 2 dividing the channel into working spaces 6, and the other having passages 11 for one or more rotatable pistons 4 which are in the form of hollow cylinders and have openings 8 in their walls for the entry of the abutments as the pistons roll over the abutments. Each passage opens at its ends 9 into the annular channel and is a close sliding fit, at least at its ends, on the internal and external walls of the piston, and the width of the sliding surface 2a of the abutment is wider in the circumferential direction than each of the openings 9 of the passages into the channel. Fluid passes to and from the spaces 6 through ports A, E and reacts against the pistons which have gears 17, Fig. 2, engaging a gear 18 on the member 1 so that during relative rotation between the bodies, the pistons roll over the abutments; the greater width of the surfaces 2a compared to the openings 9 effectively seals adjacent spaces 6 during the passage of the piston. The abutments may be formed wholly or partly of resilient material and/or be resiliently mounted, and the external surface of the pistons or the internal surface of the body 1 may be covered with a yielding material; the material on the body 1 may be mounted on radially adjustable segments to compensate for wear. The gears 17 may be formed on the pistons so that parts 3 of the body 1 inside the pistons can be supported at both ends, and the openings 8 may not extend the full length of the pistons so that annular bearings 13 can be provided at the ends of the pistons. The passages may be relieved except at the openings 9, as shown in the upper part of Fig. 1, to reduce friction between the pistons and walls of the passages, and seals may be provided therebetween. A space 21, Fig. 4, and other spaces at the bearings, may be supplied with pressurized fluid to balance the working pressure acting at 20 on the pistons. The spacing of the abutments is greater than that of the pistons and the abutments may be mounted on the inner body and the pistons carried on the outer body. It is stated to be known to provide the abutments with epicycloid flanks and for the abutments to have a variable height by which they adapt themselves to the pistons during the rolling-over process.

Title: Improvements in the methods of using three-electrode ionic tubes, applicable for wireless telegraphy and other purposes
IPC: H04B3/16
Filed: 1919-02-17
Abstract: 139,867. Turner, L. B. Feb. 17, 1919. Thermionic relays.-A pair of thermionic valves have their circuits arranged so that the plate circuit of each valve is coupled by a resistance or galvanic coupling to the grid circuit of the other valve. The arrangement may be employed for wireless telegraphy and other purposes as an amplifier, rectifier, oscillation generator, or as a current limiting device for eliminating interference by " atmospherics." Fig. 3 shows an arrangement in which the input electromotive force is applied at the terminals e in the gridfilament circuit of the valve 1, which comprises a battery b' and resistance r<2>. The plate circuit of the valve 1 comprises a battery B' and resistances R<1>, r'. The grid-filament circuit of the valve 2 includes a battery b<2> and the resistance r<1> of the plate circuit of the valve 1. The plate circuit of the valve 2 reacts on the grid circuit of the valve 1 by including therein the resistance r<2>. The amplified electromotive force may be taken off across the plate and filament of one of the lamps, or, as shown in Fig. 3, across the two plates. This may be applied to the grid of a third valve 3 having an indicating-instrument, for example, a telephone T, in its plate circuit. For receiving low-frequency signals, capacitative resistance coils may be used in the valve circuits, whilst for high-frequency currents the self-capacity of resistances and batteries should be as low as possible. Batteries with constant electromotive force, for example Weston cadmium cells, are preferred for the grid circuits, or the variation of electromotive force with temperature may be compensated by suitable resistances. In adjusting the circuits, r', r<2>, b<1>, b<2> may be varied and current changes in the plate circuits observed. If the product r<1>, r<2> is too large, sudden changes in the plate currents occur as the grid potentials are varied by potentiometers. The resistance r<1 >or r<2> is then reduced until the sudden changes disappear.
