Abstract: 525,936. Cleaning and tinning metals; annealing; automatic control systems. SYNCRO MACHINE CO. March 3, 1939, No. 7027. Convention date, March 18, 1938. [Classes 72 and 82 (ii)] [Also in Groups XXII and XXXV] In a method of heat-treating metal strands such as wire or strip, which may be followed by tinning, the strand is passed through an elongated ribbon-like Bunsen flame at a position in the flame close to the boundary between the burning and unburnt gases, and is then passed directly to and cooled in an inert atmosphere. The flame may be oxidizing, or the strand may be passed first through an oxidizing flame and then through a reducing flame. In the apparatus shown, wire is passed through a tube 1 comprising sections A, B, and C containing respectively an oxidizing flame, a reducing flame and an inert cooling gas ; or the section C may be cooled by a water jacket, or the wire therein may be cooled by water jets, or a water bath. The wire is then passed into a tinning pot 14 which is provided with means for automatically feeding tin thereto as required, and for determining the thickness of the coating. A supply of tin 21 is provided in a casing 19 having a perforated bottom 20 through which molten tin passes to the pot 14 when the tin 21 is heated by a gas burner 22 which is automatically ignited when an electro-magnetically operated valve 29 in the gas supply pipe is opened, this operation occurring when an electric circuit 35 is broken through the level 18 of the molten tin falling out of contact with an electrode 36. A well 12 is provided to catch any tin escaping from the tinning pot 14 through the inlet 38.

Abstract: 1384778 Storage system control DIGITRON AG 17 Feb 1972 [18 Feb 1971] 7443/72 Heading A4T [Also in Divisions G1 and G4] A pallet engaged by the telescopic fork (9) Fig. 1 (not shown) of the lifting slide (5) of a shelf conveyer (1) is accurately positioned adjacent a shelf compartment by controlling the motor for the conveyer by the output signals from photosensors 22, 27 (Fig. 3) carried by the slide conveyer and receiving light by reflection from a shelf compartment which is illuminated by a light source. Preferably each shelf support is painted with a light or luminous substance or has a reflecting strip fixed to it. In the embodiment described the output signals from the photo-sensors resulting from the reflected light are compared in comparators 35-40 with a reference signal 41 derived from an average value former 34 receiving all the photo-sensor outputs, the former 34 also controlling via a regulator 42 the intensity of the light source to keep the average illumination constant. The digital outputs A1-A6 of the comparator are applied to a logic circuit 44 to derive signals to move the conveyer upwards, downwards or to stop it. The telescopic fork may be moved in or out of a shelf compartment without a load when the second comparator output A2 is 0 and the third output A3 is 1 and with a load when the first output A4 is 0 and the fifth output A5 is 1. To detect whether a shelf compartment is full or empty a light source (60) Fig.4 (not shown) is directed on to the shelf support. The output from the regulator 42 may then be used to indicate the presence of a pallet since if the shelf is empty the regulator will react in such a way that light source 12 becomes virtually currentless. Preferably the photo-sensors 22-27 each consist of a line of three photo-cells connected in parallel to reduce errors due to faults. If the shelves are curved to accommodate for example barrels each line of three cells may also be curved.

Abstract: 1,167,497. Melt-spinning plasticized alcoholsoluble polyamides; laminates. COURTAULDS Ltd. 20 Feb., 1967 [21 Feb., 1966], No. 7463/66. Headings B5B and B5N. [Also in Division D1] A non-woven fibrous web in which the fibres are disposed at random and which may be used as a potentially adhesive interlining which can be rendered adhesive by heating, may be made by melt-spinning in a downwards direction a plasticized alcohol-soluble polyamide having a melting point in the range of 100‹ to 150‹ C. through a multi-hole spinneret to form a number of filaments and allowing the filaments so formed to fall freely on to the upper run of an endless moving belt under such conditions that the filaments are deposited on the belt in criss-cross fashion and are bonded together at their crossing points to form a self-supporting web structure. The moving belt may be moved forwards intermittently or continuously and simultaneously reciprocated from side-to-side to produce the criss-cross deposition of the filaments. Alternatively the spinneret may be oscillated in a path transverse to the path of forward movement of the operative run of the belt to produce the criss-cross deposition of the filaments. In a third modification the spinneret may be in the form of a strip having its holes arranged in one or more rows parallel to the longitudinal axis of the strip which is transverse to the path of movement of the operative run of the belt and the rate of movement of the belt relative to the rate of extrusion of the material from the spinneret may be so selected that the filaments coil back on themselves and overlap on to adjacent filaments to form the random web, the vertical distance of the operative run of the belt from the spinneret being not less than 6 inches and preferably from 12 to 30 inches. The polyamide used to form the filaments may be an alcohol-soluble copolymer of nylon 66 and nylon 6 or an alcoholsoluble methoxylated polyamide. The term "alcohol-soluble" is defined as meaning that the polyamide is completely soluble in methanol, ethanol, isopropanol or normal propyl alcohol at concentrations of at least 5% by weight at the normal boiling point of the alcohol. The plasticizer used may be a sulphonamide such as a mixture of ortho- and para-toluene N-ethyl sulphonamide or an organic ester of phosphorus. The potentially adhesive interlinings of the invention may be used in the clothing industry for bonding fabrics to other materials such as a second fabric or to a polyurethane foam.

Abstract: 404,166. Aircraft. GALLEGO Y HERRERA, F., 12, Calle de Peligros, Madrid. March 14, 1933, No. 7732. Convention date, March 14, 1932. [Class 4.] A flying machine is provided with a compressor and a reservoir 1 for air compressed thereby which communicates with the leading edge of supporting planes to discharge a stream of air tangentially over the upper curved surfaces only in such a manner as to support and propel the machine. In one form, the air compressed by a screw propeller is heated by the engine M on its passage to the planes. Arcuate adjustable plates 4 direct the issuing air and control of these plates facilitates steering. The action of the plates may be combined with that of the ailerons 7. The bases of the passenger compartments are made of celluloid and the landing gear is retractable under the action of the air current set up by forward motion of the craft and released by the pilot to fall under the action of gravity on landing. Fuel tanks G are arranged as shown. In a modification, suitable for flying at high altitudes, the fuselage is set back from the leading edge of the planes. Control in this case is by the ailerons and the air after being heated by the engine is circulated through ducts 16 to prevent formation of ice on the craft. The pilots can shut off communication with the engine through passages 21 in the fuel tank by doors 17, doors 18 being then kept open, but when flying at high altitudes the doors 18 are closed, air being supplied to the cockpits by opening the doors 17. The compressor may include a series of air-screws and air contained in a reserve reservoir may be used in case of failure of the engine.
