Abstract: 1,268,375. Coating apparatus. J. E. THOMPSON. 6 June, 1969 [6 June, 1968], No. 26988/68. Heading B2L. [Also in Division Fl] Coating apparatus comprises a delivery member having at least one internal passageway communicating at one end with a source of flowable material and also communicating with at least one valve-controlled capillary orifice provided in the delivery member, and pump means for supplying the material to the passageway to cause the opening of said valve and to permit the delivery of blobs or globules of the material for the orifice. Heated thermoplastic adhesive flows from a reservoir 1 through a passageway 6 in a static body 2, to a passageway 7 in a cranked rotary delivery body 8 journalled in bearings 11, 13 and driven via shaft 12, passages 6 and 7 communicating via a seal 14. Communicating with passageway 7 is a plurality of orifices 15 each of which is closed by a nozzle 19 having a capillary passage. A spring 18 shutting nozzle 19 biases a ball valve 17 against a shouldered portion of orifice 15 to close the latter. Pump plungers are operated intermittently in body 2 to force liquid adhesive past the balls 17 and through the nozzles 19 normally when the nozzles 19 are in the lowest position, to deposit globules of adhesive on a substrate moving therebeneath. The motion of the substrate may be at right angles to the axis of passageway 7 to form separate globules, or parallel to passageway to form continuous lines. Body 8 may also be reciprocated parallel to the axis of passageway 7 for producing a pattern of globule deposition. In a modification, the nozzles are arranged peripherally on a cylindrical or disc-like delivery body. The globules may be discharged on to a sheet of material to which they do not adhere and carried by a conveyor belt, the solidified globules thereafter being removed from said sheet, or the globules may be discharged into a trough of cold water to solidify individually.

Abstract: 684,085. Compound sheet materials. AMERICAN CYANAMID CO. Oct. 8, 1947. [Oct 25, 1946; Oct. 25, 1946] Nos. 27002/47 and 27003/47. Class 140. A transparent, protective surface finish is produced on wood, a decorative laminate, or other material, by heating in contact therewith a layer of paper made wholly or mainly of transparent, organic artificial fibres which has been impregnated with a heat-curable synthetic resin which, when cured, is transparent and has a refractive index differing by not more than 0.23 from that of the artificial fibres. The paper may be made from a mixture of viscose or acetate rayon fibres and fine grass fibres, and may be treated with regenerated cellulose to increase its wet strength. The synthetic resin may be melamine- or ureaformaldehyde resin as an aqueous or aqueous alcohol solution or a syrup, or an alkyd resin which may be modified by copolymerising with styrene or diallyl phthalate may be used. Suitable resins are made by reacting glycol, diethylene glycol, fumaric acid, and phthalic anhydride, and copolymerising the product with styrene or diallyl phthalate. Benzoyl peroxide may be added as catalyst, and paratoluene sulphonic acid as a gel-promoter. The resin may be applied to a polished steel pressplate and the paper smoothed over the coating, after which the assembly is heated to part-cure the resin and hot-pressed on to wood which has been similarly coated with partly-cured resin. The press-plate may be embossed and may be pre-treated with a parting agent such as soya bean lecithin, petroleum jelly, or a silicone lubricant. The surfacing treatment may be applied to plywood simultaneously with its formation by glueing the veneers together. Two superposed sheets of paper may be applied. Burn-proof table tops may be made by including a layer of aluminium foil beneath the top wood veneer. Sheets of paper impregnated with phenol-aldehyde resin may be interposed between the aluminium foil and the adjacent wood veneers.

Class 40(7) The invention relates to magnetic direction-finding aerial systems consisting of a rotatable coil wound around a. highly permeable core 2 and surrounded by symmetrically arranged highly permeable pole pieces 4 each connected to a radially extending highly permeable pick-up element 1. Such aerial systems when in use may be sited in such positions that the incident field is distorted by the presence of conducting surfaces and this results in quadrantal error. According to the invention a compensating arrangement for this error consists of additional highly permeable elements placed perpendicular to some or all of the elements 1 at their outer extremities. The additional elements may be of varying lengths, cross-sectional areas and/or permeabilities so as to provide the required compensation in given surroundings. A mathematical discussion as to the compensation affected and the conditions necessary to avoid distortion is given. Specifications 719,526, 763,886 and 764,032 are referred to.

Abstract: 814,208. Wafer-baking machines. SCRIBBANS-KEMP Ltd. Oct. 2, 1957 [Sept. 7, 1956], No. 27419/56. Class 28 (1). A wafer-baking machine consists of a series of pairs of hinged plates, carried on an endless chain, which are automatically closed together after receiving batter and then pass through an oven, after which they are opened and the wafers are positively lifted by suction and deposited either in a stack or on a conveyer. Fig. 1 shows a pair of wafer baking plates 1 travelling towards a discharge position at which a wafer is being removed from a preceding plate la by a suction device 2 to which suction is applied through a flexible conduit 4 connected to the hollow piston-rod 4a. Suction device 2 is reciprocated by a pneumatic cylinder 3 supported by two pairs of pivoted arms 5, 6, reciprocated with device 2 and cylinder 3 by a further pneumatic cylinder 7 operating through a connecting rod 8 and a link arm 9 acting on a shaft 11 on which arms 6 are mounted. In the retracted position, dotted lines, Fig. 1, suction device 2 is located over shoot 12 when a bellcrank lever 14 pivoted at 15 and actuated by link 16 pivoted at 17 on rod 6 actuates valve 13 to release the suction and deposit the wafer in shoot 12. In operation, cylinder 7 is energized to move arms 5, 6 to the full line position, Fig. 1, after which cylinder 3 is energized causing the suction device 2 to move forward and lift the wafer. Cylinder 18 is then energized, causing shaft 19 on which arms 5 are mounted to travel along the slot 21 cut into carrier 22, raising suction device 2 from plate 15 when cylinders 3 and 7 operate in the reverse direction to withdraw device 2 and move arms 5, 6 to the position shown in dotted lines, Fig. 1. Fingers 29, 29a, Fig. 4, pivoted at 30, 30a, to plate 1 are linked to the hinge so that they are retracted as the plates open, having held the wafer on the plate as the plates begin to open.
