Title: Improved icing detector
IPC: B64D15/20
Filed: 1954-03-26
Abstract: 739,527. Meteorological instruments. NATIONAL RESEARCH COUNCIL. March 26, 1954 [April 13, 1953], No. 8950/54. Class 97 (3). An instrument for detecting icing conditions in an airstream comprises a tubular probe supplying air to a pressure-responsive device connected to indicating means, the probe having at least one upstream pressure hole with a baffle of substantially greater effective area behind it. Preferably, the baffle is less than 0.026 inch behind the hole. The hole may be formed in the wall of a probe of circular or rectangular cross-section, with a curved or flat plate behind it. The baffle may have a hole in it, offset from the pressure hole. The probe may have a figure-ofeight cross-section, the rear wall approaching close to the front wall in which the pressure hole is formed so as to act as a baffle. In Fig. 16, the probe 80 has upstream and downstream pressure holes 81, 82 respectively, and is fitted with an inner tube 83 having a flattened side 84 opposite holes 81 forming a baffle and having holes 85 formed therein offset from holes 81. In Fig. 18, the probe 90 extends outwardly from the wall 91 of an aircraft and is connected by a pressure tube 92 to a pressure-operated switch. The probe has upstream and downstream pressure holes 94, 95 respectively. The upstream pressure holes 94 are formed in a tube 96 surrounding a tube 97 which extends up to wall 91 and has holes 98 offset from holes 94. As is customary, the switch, when operated by the change in pressure resulting from the obstruction of holes 94 when ice is formed, gives an indication to the pilot that icing conditions obtain, and switches on a heater 93 so that the holes 94 are periodically freed.

Title: Improvements in or relating to the manufacture of laminated wood-fibre board
IPC: D21J1/00
Filed: 1961-03-13
Abstract: 939,863. Laminates; fibreboard. SVENSKA CELLULOSA A.B. March 13, 1961 [March 14, 1960], No. 9150/61. Classes 96 and 140. Hard or semi-hard bodies consisting essentially of wood fibre material are made by compressing an initially loosely felted wood fibre sheet to approximately its final thickness at high pressure and temperature and simultaneously uniting it with one or more, relatively thin, highly flexible sheets of paper impregnated and/or covered with a binding agent. The initially loosely felted sheet is obtained by the sedimentation of wood fibres in air, or by the sedimentation of wood fibres from an aqueous suspension followed by drying to a moisture content of less than 20%. The wood fibre sheet may be moistened before the impregnated or covered sheets are applied. These may be applied immediately before the pressing. The binding agent may be a heat-hardenable synthetic resin, e.g. urea-formaldehyde, melamineformaldehyde, or phenol-formaldehyde, or an oil polymerizable by heat or a derivative thereof, e.g. linseed oil, chinawood oil, soya oil, tall oils, tall oil derivatives or castor oil alkyds, which may be used in an emulsified state or with the addition of an additional binder, e.g. carboxymethylcellulose, melamine - formaldehyde, phenol-formaldehyde, or urea-formaldehyde synthetic resins, polyvinyl chloride, polyvinyl acetate, polymethyl methacrylate, starch, soya flour, tall oil or tall oil derivatives of casein. When the binder is emulsified, oleic acid may be used as emulsifying agent. The paper sheet may be coloured or patterned, and several layers may be used. It may be impregnated with the binder, or it may be coated on one side with a synthetic resin that will form a surface of the finished article while another, cheaper synthetic resin is applied to the fibre board to bond the layers together, or it may be impregnated with two different synthetic resins, or the outer surface may be free of synthetic resin. The surface may be porous enough to provide a key for paints and lacquers. When the binder is a polymerizable oil it may be hardened by heating after the pressing operation. In example 1 the loosely felted sheet is formed by sedimentation in air of wood fibres containing about 2% of phenol-formaldehyde resin.
