IPC: B05D5/10
Abstract: 1,143,571. Coating. TELCON PLASTICS Ltd. 29 March, 1966 [29 Dec., 1964], No 26748/64. Heading B2E. A method of coating sub-strata with an adhesive comprises lowering the temperature of the adhesive when substantially solvent-free until it can be reduced to a fine powder, reducing it to a fine powder, and applying a sufficiently uniform layer of the powder to the substratum to ensure that, when the temperature of the adhesive is raised, the particles fuse together to form a substantially uniform coating. The adhesives are of the kind that cannot at ambient temperature be reduced to a powder and when substantially solvent free are at ambient temperature either solid or of such high viscosity that they cannot be applied by liquid coating methods without using solvent or raising the temperature e.g. heat sensitive, "hot 'melt" and solvent adhesives. The substrata may conductive or non-conductive sheet material e.g. papers, cloths, board, metal foils, plastics sheets. The adhesive may be frozen in a liquefied inert gas e.g. nitrogen and ground in an atmosphere of the gas. Active components or fillers of the adhesive may be   mixed before or during grinding. The powdered adhesive may be applied by electrostatic spraying or by electrostatic coating from a fluidized bed. In the Examples (1) cloth and aluminium foil are coated with "hot melt" adhesives e.g. an adhesive containing polyisobutylene, hydrogenated rosin, polyethylene, cyclised rubber and fillers and having a "tack" point of 75 to 80‹C, pressure sensitive adhesives containing polymeric materials such as ethylene-vinyl acetate copolymers, polyvinyl ethers, polymerised alkylated styrenes, wood rosin and its derivatives, terpene resins, coumarone indene resins. The pressure sensitive, melt adhesive coating is fused using infrared heat and immediately cooled, or laminated with another material; (2) solutions of solvent adhesives such as those based on natural or synthetic rubber e.g. butyl rubber, polyisobutylene, neoprene, nitrile rubber, a resin such as wood rosin and derivatives, terpene resins, coumarone-indene resins and a softener such as mineral oil, wool fat alcohol, ester plasticizers, are free-ground after removal of solvent and applied to say a plastics sheet; (3) heat sensitive adhesives such as copolymers of vinyl chloride, acetate mixed with plasticiser e.g. tricresyl phosphate, di-2-ethylhexyphthalate, nitrocellulose mixed with raw castor oil, polyvinyl acetate mixed with triglycol di-2- ethylbutyrate as plasticiser, ethyl cellulose mixed with beeswax or hydrogenated methyl abietate, vinyl polymers with phthalate plasticizer are applied.

Abstract: 1,225,809. Safety device for gas burners. SOC. LYONNAISE DES APPLICATIONS CATALYTIQUES. 18 Dec., 1968 [26 Feb., 1968], No. 60063/68. Heading F4T. A safety device for gas-fuelled apparatus comprises a combustion chamber 1 containing the tip of a pilot burner 3, a thermosensitive element 5 located in the immediate proximity of the tip of the pilot burner, and flameretaining means, such as a grill 6, located such that when the atmosphere within the chamber is of normal composition, the pilot flame 4 does not reach the flame-retaining means, but if the atmosphere becomes contaminated, in particular by an increase in the CO 2  level, the flame becomes detached from the burner tip and is caught on the flame-retaining means so that the thermosensitive element 5 is no longer heated, and on cooling, shuts off a gas supply valve associated with the gas-fuelled apparatus. As shown, the combustion chamber is in the form of a tube having openings 2, 7 to the atmosphere which are grilled and the thermosensitive element 5 is the bulb of a thermostat. Fig. 3 shows the device used in the gas flow system of a catalytic burner 20, the valve 10 being not completely closed even when the outlet 15 is closed, thereby allowing in this position a limited flow of gas to the burner 20 and to the pilot burner 3.

Abstract: 1,228,068. A naval combat game. L. GODMER. 2 April, 1969 [16 April, 1968], No. 17141/69. Heading A6H. A game of the naval combat type for two players is played on a board as shown in Fig. 1. The two playing areas 5 are of insulating material and have parallel and orthogonal rows of holes in them. As shown in Fig. 2 these holes are stopped in their middle portion by plugs of conducting material. The two playing areas are connected by the hinges 3 to the central indicating panel 4 which consists of a conducting plate 16 through which are screwed low voltage electric lamps. Connected to this plate is a lead 13 which connects via the battery 14 to the probe 15. Also provided are multipronged conducting riders 10 which plug into the underside of the playing area. These represent fighting vessels, the number of hits required to sink the vessel being determined by the number of prongs. Each type of rider is connected electrically to one of the indcating lamps. At the beginning of the game each player folds up his playing area and inserts the various conducting riders unseen by his opponent. The playing areas are then folded down into their playing positions and the players change ends. They then take it in turns to "fire a salvo" that is probe a hole in their opponents playing area. If a salvo strikes home a bulb will light up and indicate the type of vessel hit. Each hole probed is marked by plugging it with a coloured plug, the colour of the plug indicating a hit or a miss. A modified board (see Fig. 4 not shown) is also described.

A method of crimping a channel-type clip 1 to clamp a wire or wires between the bottom 1a and flanges 1b of the clip comprises superimposing while folding the flanges inwardly towards the bottom of the clip a compressive stress acting upon the channel wall towards the channel bottom said stress exceeding the limit of elasticity of the metal during the folding operation. The wires are positioned by triangular tabs 2 located in the bottom of the clip. To protect the end surfaces of the clip a channel section 5 of insulating material, e.g. rigid polyvinyl chloride, is used. A crimping tool comprises a punch 27 provided with projections 4 for piercing the channel bottom to form sharp edged projections to engage the wires. The punch slides between two side members 28 of a folding and compressing die whose flat portion 29 exerts the compressive stress on the flanges whilst they are bent by the curved lead-in portion 30 to form the folded joint. Thus during the folding operation bending stresses are superimposed on a high compressive stress and the completed joint shows no tendency of springing back.

Abstract: 1,257,678. Measuring length. ABBEY ELECTRONICS & AUTOMATION Ltd. 20 Feb., 1970 [20 Feb., 1969], No. 9200/69. Heading G4H. A device for measuring the length of a ferromagnetic wire records magnetic marks on the wire at preset intervals and counts them. The wire 1 passes an erase head 8 which demagnetizes it, a record head 6, and a pick-up head 7, a predetermined adjustable distance from the record head 6. The pick-up comprises a Hall plate into which an oscillator 14 and amplifier 15 feed a 50 kc/s. signal. The output from the pick-up passes through a pre-amplifier 17, an amplifier 19, to a phase-sensitive discriminator 16 into which a reference signal from amplifier 15 is also fed. Schmitt trigger 20 is switched as the signal increases as a mark approaches and switches off as the signal subsequently passes through zero, triggering monostable 11 and causing a work to be recorded on the wire. When this work reaches pick-up 7 the cycle repeats itself. Thus by counting the works, the length of the wire may be measured. A thermistor 3 is used to provide temperature stabilization of the output from the Hall plate. The apparatus may be used to measure the velocity of the wire, and to control the rate at which the wire 3 is wound on to a mandrel.

[Also in Division F2] A belt having reinforcing cords, e.g. of steel, between cover plies of resilient material is made by applying a pressure of 500-800 p.s.i., to compress the assembly in sequential sections but without vulcanizing. The belt may subsequently be vulcanized at a lower pressure under controllable tension, optionally after storage. The cords and/or the plies may be heated before pressing. As shown, cords 13 are aligned in a parallel layer by guides 14, 15 and pass through a first clamp 16, a cleaner 17, a tensioning device 18, a cold platen press 20 and a second clamp 37. The press 20 is movable on rails 21 and carries reels 25, 26 of sheeted covering material. In operation, the clamps 16, 37 are closed and the cords 13 are tensioned by the device 18. The press 20 is moved to its dotted-line position and actuated. The tension is then removed, the clamps are released, and the actuated press is moved to the right to draw the cords 13 forward. The clamps are re-engaged and tension re-applied, and the press is released and moved to its initial position, thereby bringing fresh covering material within the press. The cycle is then repeated. In an alternative arrangement the clamp 37 is movable and the press 20 is fixed. Before pressing the cords 13 pass through a chamber 32 where they are heated by warm air flowing via ducts 34, 35. Radiant or induction heating can also be used. If the belt is to be vulcanized without storing, it is allowed to hang limp before being passed under tension through a continuous rotary vulcanizing apparatus (Fig. 3, not shown).
