Title: Improvements in methods of lining walls, in particular concrete walls
IPC: B65D90/04
Filed: 1952-06-24
Abstract: 728,229. Granular materials adhered to fabrics. FERRIER, J., and BOUE, J. June 24, 1952 [July 9, 1951; Sept. 17, 1951], No. 15882/52. Class 140. [Also in Groups X and XXIX] In the preparation of metal or plastic sheets for use as linings of concrete walls, the sheets travel under hoppers to receive coatings of glue and granular material and then under compacting rollers; they may pass through a drying oven after the glue is applied. Plastic sheets may be softened before being coated. In one form, sheeting of plastic material from roller 13 is coated with adhesive layer 5 and by granular material 6, and the coated sheet is rolled by roller 10. The granular material may, however, be secured directly to a heat-softened plastic sheet, either through hoppers or by transfer from an endless band, or the granular material may be sprinkled on the plastic sheet and rolled in. The plastic sheet may be partially fused with the adhesive, where such is used, to obtain better adhesion. Sheets may be of polythene, " Teflon "( Registered Trade Mark), polyamides, vinyl chlorides, or rubber. Granular material may be sand, gravel, crushed brick, clinker, emery, infusorial earth, colloidal clay, &c.

Title: A method for etching glass
IPC: C03C15/00
Filed: 1957-05-20
Abstract: 803,850. Ornamenting glass. FIFE, J. G. (Coming Glass Works). May 20, 1957. No. 15959/57. Class 93 [Also in Group XVI] In a method for selectively etching a glass body with an etching fluid, a coating, which reacts with the etching fluid to exert a neutralizing effect and form a barrier to etching, is applied over that portion of the glass surface which is to remain unetched, whereafter an etching fluid is applied to the portion of the glass to be etched. The etching fluid may be dilute hydrofluoric acid, and the coating contains a watersoluble boron containing material such as boric acid, borax or other alkali-metal borates; and may also contain phosphates, and calcium chloride. Examples, (1) 10 parts H 3 BO 3 , 50 parts water; (2) 10 parts Na 2 B 4 O 7 .1OH 2 O, 50 parts water; (3) 10 parts H 3 BO 3 , 10 parts Na 2 B 4 O 7 .1OH 2 O, 50 parts water; (4) 16 parts H 3 BO 3 , 10 parts Na 2 B 4 O 7 .10H 2 O, 50 parts water; (5) 14.5 parts H 3 BO 3 , 19 parts Na 4 P 2 O 7 , 50 parts water. For perforating a glass sheet 10, Figs. 2 and 4, an opacified crystalline pattern 12 is formed in the glass by exposing it to short-wave (e.g. ultra-violet) radiations through a negative or other suitable pattern-bearing screen, and subjecting it to heat treatment. One surface is then preetched for a few minutes in a spray, stream or bath of 10 per cent hydrofluoric acid solution. forming cavities to a depth of about 10 mm. The coating is then applied to the pre-etched surface by dipping or flowing, providing a smooth continuous film 16 which also fills the cavities. The coated glass is dried at about 140 ‹C. The glass is then immersed in an etching bath. which produces cavities 20. bevelled due to lateral etching. The coating is covered before etching with a wax layer 24. After etching, the wax is removed, and the coating dissolved in warm water. The effective diameter of the resulting perforations is that of the original cavities. A glass article may be covered with resist and wax coatings and a design scribed or cut therein. On etching, cavities are formed extending laterally owing to undercutting action. Specification 699,897 is referred to.

Title: Improvements in and relating to the production of articles comprising a conductive metal pattern on an insulating support
Inventor: LYNN ROBERT ATCHESON
IPC: H05K3/34
Filed: 1955-06-03
Abstract: 841,864. Coating with metals. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 1, 1956 [June 3, 1955; June 30, 1955], Nos. 15979/55 and 18937/55. Class 82(2) [Also in Groups XXII and XXXVI] In the production of a printed circuit comprising a conductive metal pattern on an insulating support, a thin layer of solder or other suitable fusible metal or metallic alloy is provided over the metal pattern before components are secured to the pattern by a dip soldering process. Preferably the layer consists of tin-lead solder in eutectic proportions. The printed circuit comprising a copper pattern 8 upon an insulating plate, is fluxed using an alcoholic solution of colophony resin and is then passed between rollers 3, 4, the lower one of which dips into a heated solder bath. The rollers rotate continuously and the lower roller carries off a thin film of solder which it transfers to the pattern 8. Doctors 12, 13 are provided to reduce any tendency for impurities to be transferred to the pattern 8, while surface oxidation in the bath may be reduced by providing a film of resin or oil on the molten solder surface. The ensuing dip-soldering process may be carried out in a bath supplied with ultrasonic energy; this enables the dip soldering to be effected without the use of flux. The pattern 8 may be produced by any convenient process such as etching of metalclad laminate stock, electroplating, dusting with metal or transfer of the metal pattern from a preliminary support.
