Filed: 1945-06-07
Abstract: 611,309. Walls, floors and roofs. HILLS PATENT GLAZING CO., Ltd., and HINCHLIFFE, E. D. June 7, 1945, No. 14325. [Class 20(ii)] A sheet 1 of aluminium or other metal or alloy or of other material for covering the wall, floor or roof of a building has channels 2, 2a along its opposite edges and grooves 4 close to the inner sides of the .channels. One edge is turned upwards at 5. The channel 2 is slightly larger than the channel 2a, so that it can fit over the channel 2a at the edge of a similar sheet 1a. The channel 2a on the opposite edge of sheet 1 fits inside the channel 2 of another similar sheet 1b. The upturned edges 5, by fitting into the grooves 4 of adjacent sheets, prevent the interfitting channels from spreading apart. Intermediate channels, such as 6, may be formed for stiffening.

Abstract: 528,878. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., and ADKINS, B. May 16, 1939, No. 14611. [Class 38 (iii)] [Also in Group XXXV] To regulate the speed of an alternating current shunt commutator motor two induction regulators are employed, one connected to the stator and one to the rotor, the two being mechanically coupled so that the voltage is decreased as the torque falls. Fig. 1 shows an arrangement with two double unit induction regulators. The primaries 5a, 5b of one regulator 3 are connected to the supply 2 and the secondaries are connected in series with the supply and the stator winding 7 of the motor 1. The primaries 8a, 8b of the regulators 4 are connected to the supply 2 and the secondaries 9a, 9b to the commutator 10 of the motor 1. In another form single unit regulators are employed, and in this case the secondary of the second regulator is connected to the commutator of the motor through an auxiliary winding in the stator of the motor. Gear such as that described in Specification 492,105, [Group XXXV], may be used for connecting the regulators. The invention is applicable to combinations of motors such as that described in Specification 526,183.

Abstract: 594,024. Coating webs. RUAU, F. F., and MOLINS MACHINE CO., Ltd. June 11, 1945, No. 14723. [Class 140] An adhesive applying device of the kind in which adhesive is applied through an orifice in a nozzle to a travelling surface comprises an axially rotating nozzle whereby any excess of adhesive is uniformly distributed around the circumference of the operative end of the nozzle. The nozzle may be positively rotated or may be, rotated by a friction device from a continuous travelling surface. A scraper may be provided to scrape the rotating nozzle to remove any adhesive from the periphery thereof. The adhesive may be milled by a device which may comprise a fixed disc 21, Fig. 1, the face of which bears against the face of a rotating disc 22 coupled to rotating nozzle 2 by being clamped between shoulder 8 and the end of part 4 while spring 19 presses the two discs together and seals the joint between the rotating parts and the fixed hollow shaft 17. Each disc has a ring of small holes 23 concentric with its axis, thus as the rotary disc rotates its holes pass over the holes in the fixed disc and the paste passing through is milled. The fixed disc comprises a long shank 24 extending along hole 6 nearly to the nozzle orifice and having one or more flats 25 on its sides to provide passage for the paste. The nozzle comprises two parts 3 and 4 screwed together at 5 while the extremity of the nozzle consists of part 30 screwed to part 3 as so capable of adjustment. A gear 15 is fixed to part 4 by means of which the whole nozzle device is rotated. A diagrammatic arrangement is shown in Fig. 7 for rotating a nozzle by frictional engagement with the web. The web 1 runs in a vertical plane and the nozzle 2 is rotated by a rubber tyred wheel 55 through the gears shown. Figure 6 shows the use of an adjustable scraper 54. Specification 594,010, [Group XXVIII], is referred to.
