Patent GB-1100473-A (GB)
Title: Modified epoxy resin and anodic coating method
IPC: C08G18/83
Filed: 1965-04-21
Abstract: Modified epoxide resins are produced by reacting an epoxide resin with the anhydride of 1,2,4 benzenetricarboxylic acid, together with an olefinically unsaturated acid.  Olefinically unsaturated acids specified are unsaturated oil acids and maleic, citraconic and crotonic acids. The modified resin may be blended with pigments, fillers, extenders and/or polymerizable monomers (including unsaturated acids).  The modified resins may be dispersed in water preferably in the presence of hydroxylamine, ammonia or an amine to give electrodepositable coating compositions.ALSO:<PICT:1100473/C6-C7/1> A method of anodically depositing coating material comprises immersing an electrically conductive object in an aqueous bath having dispersed therein a synthetic resin prepared by reacting on epoxide resin with the anhydride of 1, 2, 4-benzenetricarboxylic acid, together with an olefinically unsaturated carboxylic acid while the object (anode) is in electrical connection with a cathode spaced apart from it and transmitting a direct current flow of electrical energy through the bath.  The resin may be dispersed with the aid of NH3, NH2OH or an amine and the bath may also contain pigments, fillers, extenders and/or polymerizable monomers.  In the preferred embodiment the electrolytic tank 11 forms the cathode and the article 19 is carried to the bath 13 on a conveyer 35 by hangars 21 and 23 with insulators 25 and 27 whilst in electrical connection with a bus-bar 33 by a means of sliding contacts 29 and 31.

Title: Process for the production of polyvinyl chloride compositions having high impact strength and compositions obtained thereby
IPC: C08F279/02
Filed: 1964-04-22
Abstract: Polyvinyl chloride compositions of high impact strenght may be prepared by mixing suspension polymerized polyvinyl chloride with an intimate mixture of an emulsion polymerized polyvinyl chloride and an emulsion polymerized terpolymer of 50 to 75% by weight of butadiene, 20 to 30% by weight of styrene and 5 to 30% by weight of acrylonitrile, said terpolymer constituting 1 to 50 weight per cent of the composition.  The suspension polyvinyl chloride may be prepared by polymerizing vinyl chloride in aqueous suspension in the presence of lauroyl peroxide or azobisisobutyronitrile as catalyst and polyvinyl alcohol, methyl cellulose, starch or gelatin as suspending agent. The terpolymer may be prepared by copolymerizing the monomers, optionally together with up to 3% by weight of a cross-linking agent such as divinyl benzene, in aqueous emulsion in the presence of a catalyst, e.g. hydrogen peroxide, ammonium persulphate, potassium persulphate, cumene hydroperoxide or p-menthane hydroperoxide, and emulsifiers, e.g. soaps, alkyl sulphates, hydrocarbon sulphonates, fatty acid monoglycerides and polyethylene glycol ethers.  The vinyl chloride polymer emulsion may be prepared by polymerizing vinyl chloride in the presence of similar catalysts and emulsifiers. The emulsions may be mixed and coagulated, e.g. with sodium chloride or aluminium sulphate, and the coagulate dried and blended with the suspension polyvinyl chloride. Alternatively the emulsions may be spray dried with or without prior mixing thereof, and the dried product then incorporated in the suspension polymer.

Title: Method and apparatus for the reduction of metals to powder
IPC: B22F9/08
Filed: 1919-07-04
Abstract: 150,490. Mellor, J. P. July 4, 1919. Granulating or pulverizing.-Zinc or other metal is reduced to powder by heating the metal to the highest possible temperature it can attain without volatilization, and pouring it in a thin stream upon a steam jet issuing at high pressure in an horizontal direction from an orifice, elongated horizontally so as to give a flattened formation to the jet. A convenient form of apparatus comprises a small furnace with a melting-pot for heating the metal and a chamber, enclosed except for a space in the top beneath which an inch steam pipe, flattened at the end to an opening <1>/16 in. deep, enters, and long enough to allow the jet to expand itself in travelling its length. The molten metal poured by a ladle on to the. jet a short distance from the orifice is instantly disintegrated and blown along the chamber, and may subsequently be collected, dried and screened.

In a reclining chair, which is adapted to move between three positions, a normal rest position in which the leg rest is retracted upwardly beneath the seat, an intermediate balanced position, and a fully reclined position, a seat link 24 is connected to fixed pivots 24 and 18 on a base link 10 by links 34, 30 and 20, and leg rest link 50 is connected to fixed point 38 on base link 10 by links 48 and 40. The normal rest position, Fig. 1 (not shown), is established by the engagement between an offset portion 64 on seat link 24 with a projection 66 of base link 10. A stop pin 68 on base link 10 is engaged by the lower end of control link 40 when the chair is in its fully reclined position, Fig. 4 (not shown). The control link 40 is pivoted intermediate its ends to fixed pivot 38 and its ends are pivoted to links 44 and 48 connected to the seat link 24 and the leg rest link 50, respectively. The intermediate balanced position, Fig. 3, is achieved by applying opposing forces upon the chair seat and the leg rest which are transmitted to opposite ends of the control link 40. The leg rest may be divided into two parts AL and ML, Fig. 7 (not shown), so that in the retracted position the part AL forms a downward continuation of the front surface of the seat.

An arrangement for detecting the presence of an obstacle in the path of a vehicle includes a directive waveguide aerial having at least one leaky slot, the leaky waves are directed across that path and reflections by the obstacle and/or reflecting means on the remote side of the path re-enter the waveguide to constitute a signal for obstacle detection. The leaky waveguide aerial may be a spaced helix of a single conductor, or a parallel winding of several conductors, provided with a dielectric matching layer and with an enveloping metallic shield incorporating slots of variable sizes and spacings to permit variation of the radiated beam axis relative to the longitudinal axis of the helix and to permit variation of leakage magnitude; a horn concentrates the beam in the horizontal plane. The reflecting means may be a corrugated plate with the corrugations so orientated and dimensioned to reflect energy back to the leaky waveguide such that it travels back to the transmitting end of the waveguide but is of reduced amplitude when an obstacle is present. A common reflector may be used for a double-track railway, which also need have only one leaky waveguide, between the two tracks, if reflectors are placed at the two boundaries. The preferred leaky waveguide structure is the subject-matter of Specification 1,113,665.

Abstract: 186,665. Hettinger, J., and Vandervell & Co., Ltd., C. A. June 22, 1921. Photographic recorders. -In an arrangement for photographically recording electric signals, a transverse line of light falls through a slit upon a moving sensitized tape, and the signal currents vary the illumination so that a record is obtained the depth of tone of which depends upon the strength of the signals received. The source of light is an incandescent lamp influenced by the signals in the manner described in Specifications 130,368 and 185,551, [both in Class 40 (v), Wireless signalling &c.]. Adjustment may be made so that normally the light just affects the tape signal impulses ot opposite sign are then recorded as lighter and darker than normal. Two simultaneously received messages may be recorded, superimposed, by one lamp and slit, provided that the strengths of the signals are different for the two messages. Preferably, two lamps are used with two slits end to end, arranged so that, as the luminosity of either lamp increases, that of the other decreases. Fig. 8 shows a record made with this arrangement. A number of lamps, say five, associated with currents of different frequencies and with a corresponding number of slits, end to end, may be used for recording letters &c., the signal impulses being selectively received to affect corresponding lamps.
