Patent GB-1105358-A (GB)
Title: Method of producing coated articles
IPC: B44F9/02
Filed: 1966-03-21
Abstract: 1,105,358. Ornamenting; printing special designs. M. LADNEY. 21 March, 1966 [10 June, 1965], No. 12257/66. Headings B6C and B6G. A method of producing a workpiece having a simulated wood grain finish comprises forming a die with a surface having small projections thereon which simulate in reverse the appearance of the small depressions in a wood grain surface, forming the workpiece against the surface of the die such that the projections form depressions in the surface of the workpiece which simulate the depressions in the wood grain surface, applying to the textured surface of the workpiece, a base coat having the colour desired in the depressions of the finished simulated wood grain surface, applying over the base coat a ground coat which does not penetrate into the depressions of the textured surface, the ground coat being of a colour lighter than the base coat and corresponding to the desired background colour of the wood grain finish and thereafter applying over the ground coat the desired simulated wood grain pattern of a colour which is substantially the same as the colour of the base coat. When the workpiece is of a plastics material the die is in the form of a mould and if the workpiece is of metal the die is of the stamping type; the base coat is applied by spraying so that it penetrates into the depressions and is of the type which when dry provides the somewhat porous surface capable of absorbing the ground coat, such as a nitro cellulose lacquer, plasticized with non- drying alkyd and di-butyl phthalate. Drying of the base coat is helped by subjecting it to a temperature of 170‹ F. for about 20 minutes. The ground coat is of the pigmented plastioizer type having a high degree of opacity and is of a material which does not dry in the atmosphere to enable it to be applied by means of a roller coating apparatus so that it does not penetrate into the depressions; it is absorbed into the porous base coat to give a dry surface. A suitable ground coat is pigmented di-butyl phthalate. Instead of being applied by roller coating apparatus the ground coat can be applied by a printing apparatus or hot stamping. Absorption of the ground coat into base coat is facilitated by drying it at 170‹ F. for half an hour. The simulated wood grain pattern is applied over the ground coat by conventional roller printing and the coat is of the non-drying type which is absorbed into the base coat, a suitable material is again pigmented di-butyl phthalate. Finally a transparent film is applied over the simulated wood grain pattern, a suitable film being a clear lacquer.

A semiconductor device having only one PN junction comprises a semiconductor wafer of one conductivity type one face of which is attached to a mechanical backing of the same material of similar conductivity type and a region of opposite conductivity type at the opposite face of the wafer. In one embodiment an N type silicon wafer 70 (Fig. 2) is fixed to a slab 74 of heavily doped N type silicon by coating the abutting surfaces with a gold anitmony alloy 72, 73 and heating to fuse the alloy. The wafer is then reduced to a thickness of 5-15 mils by grinding and etched. A PN junction is formed on its surface by evaporating on an acceptor material 82 (Fig. 3) and heating and cooling to form a recrystallised P type region 81. Where it is desired to form a number of PN junction diodes a series of wires or pellets containing acceptor material are applied or acceptor material is applied through a multi-apertured mask. After formation of the recrystallised zone or zones the wafer may be diced to form a plurality of diodes. The PN junction may alternatively be formed by passing current through an acceptor coated wire contacting the wire surface. Specifications 768,740 and 807,728 are referred to.

Abstract: 316,246. Clarke, H. M. April 26, 1928. Loud-speakers; magnetic instruments.-In a loud-speaker or microphone of the moving-coil type, an additional winding coaxial with and of axial length at least equal to that of the moving coil is provided to produce a magnetomotive force in opposition to that in the latter, and having a distribution and position substantially the same as that produced by the current flowing in the moving coil. The additional coil may be of enamelled copper wire and in two parts a, b on either side of the moving coil e, the coil a being wound on the central pole c of a pot-magnet and insulated therefrom by a paper ring, the turns being cemented together by celluloid cement, while the coil b is wound on a former, removed therefrom and attached to the outer pole-piece d. Coils a and b each have half the number of turns of the moving coil, have an axial length at least equal to that of the latter, and are connected in series with each other and the moving coil. in such a way that the resulting magnetic effect is a minimum. Alternatively, the additional coil may be in the form of two highly conductive metal cylinders, one within and one around the moving coil, and of axial length equal to or greater than the latter. The additional windings may in other modifications be non-rigidly suspended in such a position relative to the moving coil as to produce the required effect. The additional windings may be electrically connected in series or parallel with the moving coil or alternatively to one winding of a transformer (e.g. a secondary winding) and the moving coil mav be connected to another winding (e.g. another secondary winding) of the same transformer, or the two coils may be connected to different tappings on one winding. In each case resistances, capacities, or other means by which an adjustment of the magnetomotive force in the additional coil and its phase can be made, may be shunted across the additional winding. Specifications 250,931 and 252,228 are referred to.
