Abstract: 1,091,040. Electric motors. SIEMENSSCHUCKERTWERKE A.G. May 31, 1966 [May 31, 1965], No. 24307/66. Heading H2A. [Also in Division H1] An electrical signalling device comprises three magnetic sensitive semi-conductor resistors positioned between fixed and rotatable parts of a magnetic circuit, the rotators consisting of three disc sectors at 120-minute intervals so that on rotation, concentrated magnetic field successively penetrates the resistors. In Fig. 1, rotatable cams 3, 4, 5 are positioned between pole shoes 6 and 7 to lie over magnetic sensitive resistors 8, 9 and 10; magnetic screens 13 prevent field interference. The resistors may be connected in the base-collector circuits of three transistors, the collectors of which supply three load impedances (Fig. 4, not shown). In a modification, the three resistors consist of tracks extending like comb teeth from a common electrode strip (Fig. 3, not shown) and are connected in the base emitter circuits of three transistors; the collectors supply the loads and thermistors (R11, R12, R13) may be included in the base collector circuits to compensate for temperature variation of the magnetic resistors. The resistors may consist of indium antimonide or indium arsenide, if desired with needles of nickel antimonide to form an anisotropic body, and may consist of deposited layers ground and etched to the desired thickness (e.g. 5 to 25Á) and pattern.

[Also in Division D1] In coating the surface of a flexible support in sheet or web form, the support is applied by suction to the curved surface of a rotary cylindrical drum and while on the drum is passed in front of a device for coating the outer side of the support with a liquid coating medium capable of drying to a permanent coating, the coating being then at least partly dried whilst the support is still maintained under suction. In the arrangement shown sheets 20 are fed from conveyor 21 on to the surface 4 of a perforated drum 1. The drum 1 is mounted for rotation on suitable bearings and is divided internally by fixed partitions 7, 8 into a chamber 10 which is partially evacuated and a chamber which can be subjected to excess pressure. Around the periphery of the chamber 10 part of drum 1 is arranged first a coating applying device 11 and then drying section 12. The coating applying device may be a nozzle device as shown, roller or brush applicator, an electro-static depositing means or a dip-coating device. Drying can be by heated gas or by thermal radiation. After drying the sheets are removed from the drum for example by air nozzle 29 or by the excess pressure in the second chamber of the drum and fed on to conveyor 32 which conveys the sheets through a further dryer 30 having radiating elements 31. The perforations 6 of the drum surface 4 may cover the whole surface or a part only thereof, or masking devices may be provided to mask some of the perforations according to the requirements of the coating operation. Similar apparatus can be used for coating a continuous web unrolled from a roll of the material and after coating rolled into another roll or cut into lengths.

Abstract: 1,252,651. Granulated ammonium salts. PRODUITS CHIMIQUES PECHINEYSAINT-GOBAIN. 20 Jan., 1969, No. 3141/69. Headings C1A and C1B. Substantially dry granulated or microgranulated ammonium salts are prepared by introducing into a single reaction zone having a generally horizontal axis and containing substantially dry ammonium salt particles, gaseous ammonia and a finely dispersed liquid inorganic acid or acids in close proximity to each other while causing the salt particles to move in a circular manner round the axis of the zone and removing the simultaneously granulated and dried ammonium salt particles obtained from the neutralization of the acid(s) by the ammonia from the zone. Suitable acids are phosphoric, sulphuric or nitric industrial acids or a mixture of two or all three of these. The phosphoric acid preferably has a concentration of 30-70% of P 2 O 5  and the nitric and sulphuric acids have a concentration of 50-99%. The granulated ammonium salts produced are used as fertilizers or as raw materials for the preparation of complete fertilizers. Additional salts required in the final product, e.g. KCl, NH 4 NO 3  are introduced into the reaction zone in immediate proximity to the acid(s) in the form of a concentrated aqueous solution or as a mixture with the acids. The process may be operated continuously by recycling to the reaction zone the granulated ammonium salts, optionally ground, the recycling ratio being between 1 and 5. In this case the additional salts may be introduced simultaneously with the recycled ammonium salts. The rotary tube for mixing the reactants is shown in Fig. 2, consisting of mixing devices 23 and 24 integral with the tube 1 and a bed of granules 25. Two devices 22 and 22<SP>1</SP> for dispersing the reagents are shown, and the acid and ammonia feed pipes are 2 and 3 respectively. The spraying device shown in Fig. 5 comprises six concentric pipes by which the dispersion of the reagents is effected, the acid solution being dispersed through pipes 2 and 33, the auxiliary fluid, e.g. compressed air through pipes 32 and 34 and the ammonia gas through pipes 3 and 35. Microgranules may be obtained by introducing the acid, NH 3  and additional salts in a direction parallel to the axis of the reactor, whereas from granules of 2-3À5 mm. they are introduced to the reaction zone at right angles to the axis of the reactor.
