Abstract: 1,127,476. Making cement &c. pipes. FIBROTUBO S.A. 18 Oct., 1966 [23 June, 1966], No. 46473/66. Heading F2P. In making fibrocement pipes a coating of a plastics material is applied to a mandrel which is then rotated so that an outer coating of fibrocement may be continuously applied thereto and until the coating reaches the desired thickness; the pipe comprising an outer fibrocement wall and an inner wall of plastics material, is removed from the mandrel and allowed to harden. The fibrocement is transferred from a drum C, rotated in a trough, to a felt conveyer belt, the water therein being removed by suction boxes D and the dried layer of fibrocement is collected on the mandrel E which is maintained in position by pressure rollers F driven by a felt belt G. Bonding between the layers of the pipe is achieved by an adhesive or corrugations or anchorage projections formed on the outer surface of the plastics material; one layer may project beyond the other at one or both ends of the pipe. A layer of asbestos, fibreglass or rock fibre may be interposed between the plastics and fibrocement layers.

Abstract: 1,192,144. Semi-conductor devices. HITACHI Ltd. 1 Oct., 1968 [2 Oct., 1967], No. 46532/68. Heading H1K. An insulating coating on the surface of a semi-conductor substrate comprises a silicon nitride film and an inorganic insulating layer containing silicon oxide and phosphorus oxide formed on the surface of the silicon nitride film. The silicon nitride film may be directly in contact with the semi-conductor substrate or may be separated therefrom by a layer, e.g. of silicon dioxide. Preferably a silicon substrate is exposed to an atmosphere containing nitrogen, ammonia and monosilane at an elevated temperature (875‹ C.) to form the silicon nitride film and then exposed to an atmosphere of oxygen and phosphorus oxychloride (POCl 3 ) at between 800‹ and 1200‹ C., preferably between 1000‹ and 1100‹ C., to form the silicon oxide-phosphorus oxide layer. The invention may be applied to a Metal- Insulator-Semi-conductor diode comprising an N-type silicon substrate and gold and aluminium electrodes, the aluminium electrode being separated from the substrate by the silicon nitride and silicon oxide-phosphorus oxide layers. A plurality of diodes is made on a silicon substrate which is subsequently divided to form the individual diodes. It is stated that the provision of the insulating layer of the invention improves the stability of the capacitance-voltage characteristics. Other applications described include a planar junction transistor having diffused emitter and base regions and an insulated-gate field-effect transistor. In both cases, selected portions of the insulating layers are removed by etching first with hydrofluoric acid and then with phosphoric acid to permit the introduction of the electrodes to the appropriate regions of the semi-conductor devices. A plurality of fieldeffect transistors may be formed in a single substrate and interconnected by metal layers applied over the surface of the insulating layers.

In a smoke detector in which a photo-resistor responsive to scattered light operates a trigger device, the voltage across the trigger device is varied inversely with the supply voltage to compensate for variations in the light source intensity due to supply voltage variations. As shown in Fig. 3 relay R1 is normally energized by A.C. supply E half-wave rectified at D2, the current during the missing half cycles being supplied by capacitor F1. Light from a lamp 14 in a labyrinth Fig. 1 (not shown) is reflected by smoke on to a CdS cell C1, reducing its resistance and allowing a neon tube B1 to strike, illuminating a photo-resistive cell C2 which connects and opposing rectifier D1 to the relay R1, capacitor Fl by-passes the non-rectified fullwave current across the relay R1 so that it becomes de-energized, initiating an alarm A. Supply voltage compensation. The standing voltage across the photo-resistive cell C1 is stabilized by neon tubes B2, B3. Neon tubes B4, B5 are connected to the lower end of the neon tube B1 so as to compensate for the change in sensitivity of the circuit due to variation in brightness of the main lamp 14 in the event of supply voltage fluctuation. Lamp failure alarm. Failure of the main lamp 14 results in photo-resistive cell C3 becoming high resistance so that capacitor F1 becomes ineffective, hence relay R1 will chatter due to the unsmoothed half-wave rectified supply.

The liquid binder system contains 50 to 98% by weight of aqueous elastomer dispersion, calculated on the total weight of the system. The elastomer, e.g. butadiene-acrylonitrile-methacrylic acid copolymer, has free COOH, and/or OH, and/or NH 2  and/or NH and/or SH groups, for reaction with the isocyanate to cross-link the binders.  Carboxyl groups react to give off CO 2 , producing a porous binder. The liquid binder may consist of an aqueous dispersion of a butadiene acrylonitrile-methacrylic acid copolymer, an aqueous solution of polyvinyl alcohol (as the water soluble hydrophilic component) and an aqueous dispersion of either stearyl isocyanate or monoethylene urea and/or diethylene urea. Typical textile materials are fibre fleeces, in particular needled matted fleeces, consisting of or containing synthetic fibres, at least part of which are heat shrinkable and preferably consisting of mixtures of at least two chemically different synthetic fibres, e.g. predominantly polyester fibres and to a smaller extent polyamide fibres. The tithe of the fibres of the fleece is preferably 0.8 to 3 Denier and the weight per unit area is preferably 150 to 500g per square metre. Advantageously the heat action for coagulation is caused by irradiation of the fleece with an infra-red radiator at 30 to 80‹C and especially 35 to 50‹C. After complete coagulation of the elastomer, the fleece is introduced into a hot air heating chamber at 100‹ to 180‹C. and heated to a temperature of preferably 120 to 180‹C. for 2 to 30 minutes and preferably 5 to 15 minutes. After leaving the heating chamber the fleece is washed with hot water and then with cold water and then dried, e.g. in a drying oven fed with air at 120 to 150‹C.
