Title: Improvements in and relating to magnetic clutches
IPC: F16D27/00
Filed: 1946-07-09
Abstract: 614,136. Clutches. BRITISH THOMSONHOUSTON CO., Ltd. July 9, 1946, No. 20500. Convention date, July 11, 1945. [Class 80 (i)] A magnetic clutch comprises two magnetic driving shaft sections 2 spaced apart by a non- magnetic member 3, a plurality of sector-shaped magnetic plates 14 which are grouped in overlapping relation to the shaft portions to form the bearing for the driven member 13 to which they are attached for limited radial movement, and means 8 producing a magnetic flux causing the plates 14 to move radially inwards to grip the shaft sections 2 and so drive the member 13 through the pins 15. In a modification, the member 3a is made wedge shape to promote a rapid reduction of flux when the flux is deenergized. In an embodiment, Fig. 5, two clutches 13 are driven by a unidirectional motor 38 and are arranged to be energized alternatively through a switch 39 to move a stylus 29 in either direction at will through the medium of a cord 33 running on idle pulleys 34, 35. The clutch may be energized either by an electromagnet or a permanent magnet.

Abstract: 674,506. Friction couplings. WESTING- HOUSE AIR BRAKE CO. Aug. 22, 1950 [Aug. 31, 1949], No. 20727/50. Class 80 (ii). [Also in Groups XXIX and XXXIV] In a wheel slip detector device for use in controlling fluid pressure operated brakes, particularly for aircraft, it is arranged for a housing member 17 rotatable with the aircraft wheels to transmit a greater degree of torque to an internally toothed ring 29 when the housing is rotating less quickly than when it is rotating more quickly than the ring. This operating characteristic is provided by arranging for the torque to be transmitted from the housing to the ring in two ways (a) by a friction ring 41 and (b) by a thrust ring 45, under steady pressure of plate spring 44, through a friction member 42. The member 42 has projections-51 co-operating.with a spring pawl 47 secured to the casing so that when the casing tends to overrun the ring 29, the member 42 becomes inoperative as far as transmitting torque. The friction ring 41 is always operative to transmit torque.

Abstract: 850,785. Moulding glass-fibre rods. SIEKMANN, K. June 27, 1958 [June 28, 1957], No. 20751/58. Class 87(2). A continuous process for making rods from glass fibres impregnated with a polyester resin comprises passing the fibres and the resin downwardly through a drawing die in a heated vacuum chamber to draw together and bond the fibres and resin and cutting the finished rods into lengths. Glass-fibre threads 10 are drawn, by a drawing device 20, from spools 5 mounted on stationary discs 1, 4, and from spools 6, 7 mounted on discs 2, 3 rotating in opposite directions. The fibres enter a funnel 11 and are wrapped with woven glass fibre 25 and impregnated with resin from a container 8. On leaving the funnel 11 the strand of fibres enters a vacuum chamber 12 and is drawn through a heated lubricated shaping die 14 wherein the resin is set. A circular saw 22 cuts the set rod into lengths. The shaping die may produce rods of shapes other than circular, e.g. 1, Fig. 2 (not shown). The shaping die may be cooled.

Abstract: 1,191,902. Foamed plastics laminate. FARBENFABRIKEN BAYER A.G. 4 May, 1967 [11 May, 1966], No. 20789/67. Heading B5N. [Also in Division D1] A process for the production of a foamed plastics article reinforced in at least its marginal zone by a crimped fibre web or webs, the web or webs consisting of smooth or structured monofils, which monofils are crimped and have an individual titre of over 40 denier, at least some of the monofils being synthetic, comprises placing the crimped web or webs in the mould in which the foaming reaction is conducted. The or each web may be made by laying and stitching monofils, may vary in thickness, may be of polyamide monofils, may include natural or synthetic strengthening agents, may also include natural, mineral, metallic, or other synthetic fibres, and may be pretreated with a compound which is capable of reacting with the reaction mixture which produces the plastics foam. The plastics foam may be a polyamide, polyurethane, phenol-formaldehyde, unsaturated polyester, or epoxide resin or P.V.C. The fibre web may reinforce the whole of the volume of the plastics foam in which case it is held in place in a mould or a hollow body by pressure or by a bonding agent whilst the reaction mixture is foamed to fill the mould or hollow body. The reinforced plastics foam may be laminated with or sandwiched between layers of metal, wood, cardboard, paper or plastics. The reinforcement may comprise webs of different densities or thicknesses, and in one embodiment a plastics foam sandwich core is reinforced in its marginal zones by webs of one thickness, and in its central zone by a thicker lighter web. Alternatively the central zone is reinforced only in localized areas. In another example the reinforcement web is thicker than the plastics foam so that it projects on one face thereof.

In a pressurized water coolant nuclear reactor, boiling in the coolant is prevented and charges in density are compensated, by means of a pressurizer vessel connected to the coolant system. The vessel contains both vapour and liquid and both heating and cooling means may operate on the contents so as to adjust the pressure of the reactor coolant system. Cooling is effected by water introduced into the upper part of the vessel through a spray while heating is effected by either electric or fluid heated tubular elements immersed in the water in the lower part of the vessel. The spray nozzle and the heaters are automatically adjusted by the coolant pressure. Corrosion of the pressurizer is prevented by an internal lining of stainless steel.

Abstract: 819,105. Laminates. AKERLUND & RAUSING A.B. July 3, 1957 [July 5, 1956], No. 21018/57. Class 140. In applying webs of paper, metal foil, felted fabric, or fabric of man-made fibres, to extruded sheets of plastic material such as polythene the thickening of the edges of the plastic sheets, which is stated to result from the extrusion process, is compensated for by thinning the edges of the webs, e.g. by grinding. Grinding may be effected by individual grinding wheels rotating in planes transverse to the direction of travel of the web and grinding towards its lateral edges. In an example,. molten polythene extruder downwardly is applied to a paper web 0.22 mm. thick in the nip of pressure rollers, the roll contacting the plastic being maintained at a temperature below its solidification point. The polythene film is generally 0.05 mm. thick but has edge beads about 7 mm. wide and 0.20 mm. maximum thickness. The paper web before lamination is thinned at its edges by grinding, to a complementary section and minimum thickness of 0.07 mm., to make the laminate of uniform thickness throughout. The product may be printed and coated with wax on the paper side. Specification 688,637 is referred to.
