Abstract: 1291735 Welding by pressure BAU-STAHLGEWEBE GmbH 8 April 1970 [12 April 1069] 16605/70. Heading B3R In a method of making simultaneously in a single welding machine two wire mesh grids, longitudinal and transverse rods or wires are fed through a wire mesh welding machine at two levels in two parallel planes and a welding beam 26 with welding electrodes 33, 34 arranged on its lower and upper edges reciprocates vertically between the two planes to weld the two grids alternately. Separate upper and lower feed devices having grippers 58, 59 operate out of phase so that one grid is advanced one mesh spacing while the other is stationary and undergoing a welding operation.. Welding pressure is provided by springs 29, 30 and the welding beam is reciprocated by an eccentric crank mechanism the throw of which ensures adequate welding pressure being generated. A common transformer 12 serves for both welding operations and, as shown, has its secondary terminals connected to the upper and lower fixed electrodes 7, 6. The transverse rods are disposed below the longitudinal rods in the upper grid and above in the lower grid so that the grids stack together without reversal as delivered from the machine. Reciprocation of the welding beam and feed of the welded grids may alternatively be effected by pneumatic or hydraulic means.

Abstract: 186,130. Fairweather, W., (Singer Manufacturing Co.). June 17, 1921. Clutches, friction; gearing for stopping and starting machinery.-In sewing and other small machines in which the mechanism for declutching the motor from the machine is arranged to cut in resistances into the motor circuit so that the motor runs at reduced speed during the idle period of the machine, a motor C is secured by housings 11, 12 on an outwardly projecting bearing-boss 10 of the main shaft 9. The shaft 16 of the motor carries a worm 17 meshing with a gear wheel 18 secured on a clutch disc 1 turning freely on the shaft 9. A hand-wheel 20 fast in the shaft 9 is clutched to the disc 19 by a ring 21 carrying pins 22 which slide in holes in the wheel 20 and are engaged by a pusher 24 to force the ring into contact with a loose ring 23 of compressed cork &c. which frictionally engages the disc 19. The' pusher is actuated by the engagement therewith of an adjustable stud 36 of anti-friction material such as oil-soaked hard wood mounted in a lever 34, pivoted on the frame and also carrying a brakeslroe 39. The lever 34 is connected by a link 42 to a lever 44 on a shaft 45 rotatable against the action of a spring by a treadle rod 48. Connected to the treadle rod bv a chain 57 is a rheostat arm 53 held by a spring 55, when the machine is at rest, on the uppermost of three contacts 54 so as to include in the motor circuit resistances r<11>, r<1>. When the treadle rod is depressed to start the machine, the resistances are successively cut out and immediately after the arm 53 meets the lowest contact the clutch is engaged. In a modified construction the motor is mounted on the standard of the machine arm within which the worm 17 and gear 18 are situated, and the driven clutch-member, directly actuated by the stud 36, carries a square-section ring of leather &c. engaging a conical driving- member.

Abstract: 798,603. Flexible hoses. RAYBESTOSMANHATTAN, Inc. June 1, 1956 [June 2, 1955], No. 16981/56. Class 99(2). A flexible, elastomeric hose comprises an inner tube 10, Fig. 1, of corrosion-resistant material and an outer tube 11 which snugly embraces the tube 10 but is substantially free of bondage thereto. The tube 11 is sufficiently thick to furnish the physical strength lacked by the tube 10 and prevent collapse thereof and the inner tube, when the hose is bent, is able to slip slightly within the outer tube. The extruded inner tube may have a thickness of from 10 to 100 mils and be of polytetrafluoroethylene or polymonochlorotrifluoroethylene, and the outer tube may have a thickness of at least 1/32 inch and be formed of natural or synthetic rubber. As shown in Fig. 3, the hose includes a reinforcement 13 in the form of single or multiple braids of cotton, wire or asbestos or helical or longitudinal wraps of cloth. The outer tube may be applied as an extrusion or a wrapping of rubber sheet, the inner tube being supported against collapse by a rigid or inflatable mandrel or by applying air or hydraulic pressure to the interior of the tube.

Abstract: 491,993. Electric signalling systems. GENERAL ELECTRIC CO., Ltd., COLLYER, J. E., and SMART, N. C. June 19, 1937, No. 17084. [Class 40 (i)] Lamps or other consuming devices of a group or sub-group thereof are switched on and off in succession by relays, one for each group or sub-group, each responsive to two signalling frequencies, one of which operates a relay to switch on its associated lamp or sub-group, the other to switch it off and also to switch on the lamp or sub-group of another relay. In the arrangement shown the lamps LA-LC, switches SA-SC and relays A-C are associated with a 3-phase supply, but they may be connected to a single phase or D.C. supply. The relays may be as described in Specification 491,980, [Group XXXVII], and have two tuned reeds, reeds 1 and 2 of relay A being tuned to frequencies f1, f2 respectively, reeds 2 and 3 of relay B being tuned to frequencies f2, f3 and so on. Consumption of power current is limited by condensers ZAZC which, however, pass the signalling frequencies. Assuming that all the switches are " off," f2 switches on LA and tends to switch off LB which is already off, f3 switches on LB and tends to switch off LC, f4 switches on LC. The lamps are switched off by applying frequencies f3, f2, f in succession. The arrangement may be extended to control any number of lamps or sub-groups.

Title: Improvements in and relating to the Manufacture of Fibres from Plastics Films Oriented in one Direction

Abstract: 1180545 Fibrillating thermoplastic polymer films KALLE A G 10 April 1968 [12 April 1967] 17226/68 Heading B5B [Also in Division D1] Fibres are made by suspending pieces cut from a film of synthetic organic thermoplastic polymeric material which has been uniaxially oriented at a stretch ratio sufficiently high to render it fibrillatable by mechanical treatment, in a liquid which is not a solvent for the film material and exposing the suspension tothe action of shearing forces which may for example, be produced by means of high-speed stirrers. The suspending liquid may be water. The film material may be a polyolefin, a polyvinyl compound a polyester or a polyether. The film may consist of two or more miscible or immiscible components, e.g. polypropylene and polyamide. The length of the piece or strip cut from the film may be from about 10 to about 40 mm., preferably 15 to 25 mm., and its width may be 5 to 50 mm. The thickness of the film may be between 5 and 40 microns, preferably 8 to 20 microns. An anti-agglomeration agent which is soluble in the suspension liquid may be added to the liquid. When water is used as the suspending liquid, polyvinyl alcohol or a watersoluble cellulose ether, particularly hydroxyethyl cellulose, may be added to the water. In addition, a surfactant such as a sodium alkyl sulphonate may be added to the water. The content of film pieces in the liquid may be 1 to 15 grams per litre. The fibres are suitable for further processing into non-woven fibrous or textile structures, particularly for the production of mats or fleeces. After separation of the fibres from the liquid in which they are suspended, such structures may be immediately formed from the resulting fibre slurry by consolidation by conventional methods and may be thermally solidified or reinforced by means of binders. In an example, 30 mm. wide strips of an 8 micron thick which has been uniaxially oriented in the longitudinal direction by stretching it at a stretch ratio of 9:1 and at a temperature of 150‹ C. Polypropylene film are cut into 5 to 20 mm. length portions, 80 grams of which are suspended in 40 litres of water containing 0À5% of hydroxyethyl cellulose and 0À15% of a wetting agent and the pieces of film are fibrillated by intensely stirring the suspension for 4 minutes. The fibres are deposited on a travelling endless screen belt to form a mat or fleece which is dried. The fibres in the fleece have good cohesive properties promoted by the binding effect of the hydroxyethyl cellulose.
