Title: Improvements in or relating to the formation of lustrous surfaces on articles such as cabinets, panelling for walls and furniture
IPC: B32B27/00
Filed: 1943-08-20
Abstract: A lustrous polished or matt finish is imparted to a partly-compressed base of fibrous material containing a thermo-hardening resin by applying a preformed film of thermoplastic material and subjecting to heat and pressure to cause further compression of the base, to cause the film to flow, to adhere intimately to the base, and to afford a lustrous finish. The base may be a layer of paper pulp, or may be laminated, comprising sheets of blotting paper, pulp board, sawdust board interleaved if desired with sheets of wood veneer, or the base may consist solely of layers of wood veneer.  The base or its constituent laminations are coated or impregnated with a solution of phenol- or amino-formaldehyde resin and pressed at 70-250 DEG  F. up to 50 lbs. per square inch to cure the resin.  An ornamental layer of wood veneer, leather, paper printed to imitate wood or leather, or metallised paper may be united with the base at this stage.  The thermoplastic film, which may be polyvinyl acetate or polyvinyl acetal, celluloid or plasticised ethyl film, which may be polyvinyl acetate or polycellulose or cellulose acetate is subsequently applied at a pressure of 250 lbs. per square inch and a temperature of 250-300 DEG  F. by means of a press platen or mould with a polished or matt surface as desired.  The film may be transparent or opaque and coloured if desired.  The product is suitable for making cabinets for radio receivers, panelling for walls and furniture.  Cabinets &c. may be built up from flat finished panels, or articles with contoured surfaces may be formed by settling pulp on a wire former, drying or partly drying, impregnating with a thermo-hardening resin, partly compressing and applying a thermoplastic foil under higher pressure. The contoured moulds for the final pressing may be of cast iron suitably finished or lined, or may be made by electroplating a model of the required article and backing the electroplate with solder or type metal.  Specification 514,172, [Group VIII], is referred to.

Abstract: 1,147,585. Molecular beams. UNITED STATES ATOMIC ENERGY COMMISSION. 11 March, 1968 [18 July, 1967], No. 11809/68. Heading G6P. In a neutral particle beam, for use in thermonuclear reactors, low velocity contaminant gas atoms are removed by irradiation of the beam with monochromatic e.m. radiation directed transversely across the beam. The charged particle beam 11, of deuterons, protons or tritons passes through housing 13, where the beam particles are neutralized, through collimating slits 18 and 9, into housing 31. The contaminant gas atoms are removed from the beam in 31 and the uncontaminated beam enters a thermonuclear device after passing through apertures 37, 38. Neutralization of the beam particles is effected by sodium vapour 21 in 13, by charge interchange. Some of the sodium vapour atoms mingle with the beam and stream into housing 31. The contaminated beam is irradiated transversely by the sodium lamps 32 the light from which is absorbed by sodium atoms in the beam. The sodium light protons impart momentum to the sodium atoms which move from the beam in the direction 36 while at the same time re-radiating the absorbed radiation in random direction. Radiation is not absorbed by the beam atoms.

Abstract: 438,849. Kinematograph projectors. DEHN, F. B., 103, Kingsway, London.- (Automotion Pictures, Inc. ; 14, West 40th Street, New York, U.S.A.) April 18, 1935, No. 12032. [Class 97 (i)] In apparatus for feeding films to the projector from the interior of a coil and simultaneously rewinding the used film on the exterior, the film is fed to a positive feed device by frictional means with a slight excess of speed, the consequent slack in the film resulting in slip of the frictional drive. The coiled film 14 is rotatably mounted outside a circle of rollers 20, 20A and is led off from the interior over a conical roller 23 to a positively driven wheel 15 and thence to the projector 12. The used film is led over a wheel mounted coaxially with the wheel 15 and then to the outside of the coil. The film is rotated and fed frictionally by an endless belt 24 running over a driving sprocket 25 and between the rollers 20 and the film. The frictional grip of the endless belt between the rollers 20 and the film and hence the rate of frictional feed depends upon the tension of the film between the guide pulley 23 and the positive feed pulley 15. As the film rotates, adjacent turns slip slightly over one another so that the dimensions of the coil are unchanged.

Successive discontinuities in a microwave band filter are alternately inductive and capacitative. As shown, each half-wavelength cavity is bounded on one side by an inductive post 3 and on the other by a capacitative iris 2. The cavities are spaced apart by one quarter wavelength with unlike reactances adjacent each other. The Specification states that if the number of cavities is odd and the absolute values of the capacitative and inductive reactances are equal to each other a symmetrical characteristic is obtained. This results from a diminution in coupling by spurious modes. In order to equalize the values of the reactances, each capacitance may be varied by means of an axially movable pin extending from the centre of the board side of the guide into a recess in the edge of the iris.
