Abstract: 773,474. Induction motors; cooling electric motors. SCHMID, W. K. Sept. 6, 1955 [Nov. 20, 1954], No. 25502/55. Addition to 740,603. Class 35. A wound-rotor induction motor whose speed is controlled by rotor-current impulses of various durations is provided with a fan 14 driven by a special squirrel-cage rotor 15 within the main stator 4 and carried by bearings 11 on the motor shaft. The main rotor speed is controlled by intermittent short-circuiting by a rotating contact drum 21 engaged by a series of brushes 28-33 which are selectively contacted by a brush 35 on contact strip 34. As soon as the sliding contact 35 moves from A to B to start the motor, brush 36 engages strip-contact 37, thus energizing relay RL which places resistor 39 across the rotor slip-rings 8, 9 to carry the bulk of the rotor current, thus relieving the contact drum 21. At the top speed, contacts 40, 41 are bridged which closes relay RS to short circuit the rotor winding.

Title: Combustible gases
IPC: C10L3/08
Filed: 1975-05-30
Abstract: 1503506 Production of substitute natural gas IMPERIAL CHEMICAL INDUSTRIES Ltd 30 May 1975 [10 June 1974] 25639/74 Heading C5E A process for the production of a substitute natural gas comprises (a) reacting methanol vapour over a catalyst having both steam reforming and methanation activity in a decomposition reactor 10, (b) cooling the resulting gas, which has an outlet temperature above 550 C., by indirect heat exchange at 12, 14, 16 to a temperature in the range 250-350 C., (c) methanating the cooled gas in methanation reactor 20 to give a gas having an outlet temperature of 500-650 C., (d) cooling the methanated gas by indirect heat exchange at 22, 24 and (e) further methanating the cooled gas in reactor 28. In the particular example described, the resulting gas is cooled at 30, 32, 34, 36, has water removed in catchpot 38, is reheated at 30, and is further methanated in dry methanator 40. Further methanation stages may be employed if necessary. The methanol feed to the reactor 10 is preheated at 32, 24, vaporized in boiler 22, and mixed with stream at 18. The catalysts used for the decomposition in reactor 10 comprise nickel and/or cobalt alone or with one or more platinum group metals, on a refractory support, the nickel/cobalt content being 25-90% by weight as metal oxide. In the particular example, the catalyst used is nickel on an alumina support, and this is also used in the methanation reactors 20, 28 and 40. The hydrogen content of the product gas can be decreased by adding a hydrocarbon such as liquefied petroleum gas or liquefied natural gas to the gases to be methanated. Steam may be produced in cooling the decomposition gas and methanol vapour is produced by cooling the first methanation stage gas. The calorific value of the product gas may be adjusted by addition of l.p.g. or liquefied natural gas. Specification 1,437,957 is referred to and relates to a process for converting methanol to natural gas substitute.

Floor covering is produced by coating a layer of textile fabric on both sides with a synthetic adhesive, bonding a layer of foam-like porous and elastic material to one side of the coated fabric and applying to the other side thereof a layer of upstanding fibres or hairs by means of a continuous electro-static flocking operation known per se, both the adhesive and the foamlike material being such as to dry or set at room temperature. The layer of textile material may be loosely woven and may be first embedded between two layers of filling material which also is such as to set at room temperature, and thereafter applying to opposite sides, respectively, of the fabric so treated, the coatings of adhesive and foam-like material. The two layers of filling material, e.g. latex, may be applied so as to show perfectly continuous and smooth surfaces, and the layer of upstanding hairs may be applied so that the free ends of these hairs show a smooth surface, being approximately all in the same plane. One of the two layers of filling material may be applied so as to show a perfectly smooth outer surface, a layer of adhesive and a layer of the foam-like material being successively applied to the layer; the other layer of filling material then being applied so as to show a relief according to a predetermined pattern, a layer of adhesive and a layer of upstanding hairs being successively applied so that the free ends of the hairs show the same pattern as that of the layer of filling material. The foam-like material may consist of polymers prepared from cyanates and amines or glycols, e.g. polyurethane. The hairs may be fibres of synthetic material. Specification 387,451 is referred to.

A machine for loading rod-shaped products, e.g. cigars, into a container 4 includes a hopper 5, to which products 21 are fed and which is provided with two members 8, 9, movable towards each other to close the hopper outlet and carrying rollers 14, 15 on their facing edges. Means (not shown) may be provided for driving the rollers in opposite directions to move cigars in their path upwardly. As shown, rod 19, carrying a plate, moves downwardly in the container to support the cigars during filling. This downward movement is initiated when the hopper is sufficiently full for cigars to cover a photo-cell 18 and is arrested if the level in the hopper falls below a certain value, sensed by a microswitch 20. When the container is full, the hopper, with plates 8, 9 pivoted about axes 12, 13 to close the hopper outlet, is raised to permit the full container to be replaced by an empty one. Hopper walls 6, 7 may be vibrated.

Abstract: 714,901. Uniting by fusion. GENERAL ELECTRIC CO. Oct. 15, 1952 [Oct. 26, 1951], No. 25881/52. Class 83 (4). In an arc-welding head having a metal guide for a consumable electrode a guide extension is provided at the arc end of the guide of non- metallic electrically-insulating material of low mechanical adhesion with respect to molten electrode metal and of a length such that if the rate of electrode consumption exceeds feed rate the arc will be extinguished before the arcing electrode end can pass from the extension into the guide. In an embodiment a hand torch has a metal guide 6 formed of two tubes 7, 8 within an insulating member 5. A cooling fluid passage is formed between the tubes 7, 8 and shielding gas and the electrode 9 are fed through the inner tube 7.

An adaptor 16 in the end of the guide 6 has transverse holes 15 for gas flow, supports an electrode contacting brush 18 and carries a guide extension 17. A flexible tube 20 encloses an electrode feed tube, a gas supply tube, cooling fluid supply and exhaust tubes, a drive shaft for a feed roll 30 and control wires. A welding current supply lead is within the cooling fluid exchange tube. The extension may be of vulcanized fibre or soapstone for aluminium electrodes to produce in an arc an arc extinguishing gas without substantial carbonization. Silicone rubber or solid polymeric tetrafluoroethylene may be used. Ceramic material is used for stainless steel electrodes. The diameter of the electrode passage in the extension is such that a globule of electrode metal will block the passage. The extension may be used in a submerged arc welding apparatus.
