Title: Tape dispensing machines
IPC: B65H35/00
Filed: 1961-02-22
Abstract: 975,258. Adhesive tape dispensers. MINNESOTA MINING & MANUFACTURING CO. Feb. 22, 1961 [Feb. 23, 1960], No. 6503/61. Heading A4G. A tape dispensing machine has an annular brush 24 of radially extending nylon bristles 25 supporting the adhesive tape T, the brush being rotatably mounted on frame 20 and driven by an electric motor. Tape is drawn from the rotatable supply roll 34 mounted on a shaft 36, on which it is retained by wing-nut 38 and a spring which control the unwinding tension and passes over guide roller 42. The tape is carried on brush 24 until its leading edge strikes actuator 49, mounted in shield 47, which acts to stop the motor and energize the solenoid 54 which in turn depresses knife 50 whose angled and serrated cutting edge severs a piece of tape on the brush. The position of the actuator 49 may be varied by rotating its mounting arm, so that the desired length of tape may be cut off. Removal of said piece of tape returns the actuator to its first position and so deenergizes the solenoid and re-starts the motor.

Filed: 1927-03-08
Abstract: 268,319. Lilienfeld, J. E. March 27, 1926, [Convention date]. Static contact rectifiers, arrangements of. - A dry-cell rectifier for alternating current comprises in combination an electrode of a powdered compound of an electropositive and an electronegative element, such as copper sulphide, which has been compressed to withstand a pressure of about four kilograms per square millimeter, and a metallic electrode, having formed thereon a plurality of projections of a relatively small crosssectional area, forced into contact therewith under intense pressure. Fig. 7 shows such a cell, the electrode 12 consisting of a ring of aluminium with rounded projections 13 which contact with the powdered and compressed copper sulphide 11 in an annular metal container 10. Two blocks of four such cells are shown in Fig. 1, mounted on a rod 20, and held in position by the members 23, 26, 27, 30, an intense pressure being applied between the electrodes by the spring 21. Shrinkage of the electrodes 11 is taken up by moving the nuts 27, and the necessary pressure is thereby maintained. The batteries of cells may be secured to a panel 37 by means of spring clips 35 having eyes 36 projecting through slots in the panel and being engaged at the back by rods 39. The panel may be provided with an opening 41 to accommodate the spring 21. The method of connection to the alternating-current input and the direct-current output is shown in Fig. 8.

Title: Method and apparatus for coating surfaces of helically grooved tubes of any length
IPC: B21C37/12
Filed: 1951-03-28
Abstract: <PICT:0716183/III/1> <PICT:0716183/III/2> In treating the surfaces of helically grooved tubes (flexible pipes) of any length which are manufactured by winding strip material on to a stationary mandrel so as first of all to form a smooth tube which is then corrugated by means of a threaded socket secured against axial displacement and consisting of a screw and nut rotating in the same direction at the same speed, after which the tube leaves the mandrel and the helical corrugations are compressed until they are in contact with one another, the tube, immediately after the compression, is provided on its outer and/or inner surface with a coating by being passed through a liquid or pasty material.  Suitable materials are paint, lacquer, rubber, or synthetic material.  In the modifications shown, bands 8 and 9 p  of material drawn from supply rolls are wound on a hollow mandrel 1.  The resulting smooth tube 10 is engaged between the threaded extension 4 which is rotated by a sprocket 5 via a sleeve 3 and the internally threaded member 7 formed on a sprocket 6.  The sprockets 5 and 6 rotate in the same direction at the same speed and the parts 4 and 7 in consequence helically groove the tube 10 and push it forward as it is prevented from rotating by engagement with the longitudinal teeth 18 and a cylindrical longitudinally slotted resilient extension 31.  These longitudinal members also cause the corrugation to be pushed together until their flanks are in contact. The tube is then coated externally by material received from a chamber 12, the thickness of the coating being controlled by adjusting a gland 15 of a stuffing box.  The inner surface of the tube is coated by means of material pumped through a pipe 21 and radial bores 24 leading to the inside of the head 22.  A brush 26 attached to the front of the head 22 completes the spreading of the inner coating.  Alternatively, the stuffing box with gland 15 may be replaced by a tapering bore 20 (Fig. 2) to form the outer coating and the longitudinal members 18, 31 may be replaced by a toothed divided clamping chuck for pushing the corrugations together.
