Patent GB-396424-A (GB)
Title: Improvements in the production of films and foils
IPC: B29C41/24
Filed: 1932-01-30
Abstract: Apparatus for the manufacture of foils and films by dry or wet methods comprises a drum provided with a tough corrosion-resistant and substantially - permanent surface of stainless steel or cold-worked nickel on which the film or foil is formed.  The surface may be formed by shrinking an endless tyre of stainless steel or cold-worked nickel on to a drum or spider of other material.  A length of nickel band may be hammer welded into endless form, the joint being rolled and ground to the thickness of the rest of the band, and the band is then cold-worked to impart the necessary toughness and to make the joint uniform in its properties with the rest of the band.  The band after slight stretching is shrunk on a spider and a final polishing is given to ensure concentricity and smoothness.  Very glossy foils are produced by deposition of solutions upon such surfaces, and the deposition of gelatine or like coatings to receive the solutions may be dispensed with.  Although the stainless steel or cold-worked nickel surface has high resistance to corrosive influences, it may be protected by a coating of wax. For the production of cellulose acetate foils, the drum may be enclosed in a casing through which evaporative medium is caused to flow, preferably in the opposite direction to that of the film.  The casing and the evaporative medium may be heated.  The solution may be deposited from a hopper which s supplied by gravity, or by pumps or other pressure devices.  Alternatively, the solution may be transferred to the drum surface by a resilient roller. Specification 396,398 is referred to.

Abstract: 979, 021. Winding wires; spindle drives. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 26, 1962 [Jan.31, 1961], No.3019/62. Headings DiD and D1J. A wire winding device has a plurality of spindles 18 on which spools 19 can be mounted, each spindle 18 being driven by an individual friction clutch 21, 22 that is adjustable to permit a variable degree of slip in the drive to the spindle independently of the drive to the other spindle or spindles, said spindles 28 being mounted in a common rotatable housing 1 and being each surrounded by a freely rotatable gear wheel 9 driven by a common shaft 3 through an intermediate gear wheel 8, Fig. 2 (not shown). Each gear wheel 9 is rigidly secured to a sleeve 10 rotatable about a hollow shaft 12. A compression spring 23, surrounding the shaft 12, urges the gear wheel 9 and the sleeve 10 against a felt ring 22 carried by a sleeve 21 rigid with the spindle 18. The pressure exerted by each spring 23 is adjustable by turning an individual control knob 31 to rotate a screw-threaded rod 30, rotation of the rod 30 causing a U-shaped member 29, that is threaded on the rod 30, to displace a collar 27 along the shaft 12, the collar being coupled to one end of the spring 23. When a reel has been fully wound the housing 1 is rotated to bring a fresh reel into the winding position. Adjustment of the clutch settings enables the tensile force exerted on a wire by each individual spindle to be carried out accurately without affecting the tensile forces set up by the other spindles.

Title: An improved method and circuit arrangement for controlling and protecting the operation of controlled gas or vapour electric discharge gaps
IPC: H02M1/04
Filed: 1936-02-04
Abstract: 470,067. Converting. SIEMENSSCHUCKERTWERKE AKT.-GES. Feb. 4, 1936, No. 3374. Convention date, Feb. 8, 1935. [Class 38 (ii)] Grid control potentials for a gas or vapour discharge device are obtained from a circuit which includes auxiliary valves by means of which the internal resistance of the circuit may be periodically varied and the control potential changed by a desired amount in two or more stages and means for shifting the phase of the resultant potential. The grid potentials are supplied from a battery 32 through grid controlled auxiliary valves 6, 7 8 which have as many anodes as there are grids in the main discharge device to be controlled. These auxiliary valves are controlled by a device 30 and one cycle of grid potential is built up as follows : The valve 6 is first made conductive and applies a positive bias to the grid 4 from the section 27-26 of the battery to start discharge in the main device. At some point in the conducting half cycle of the main device, the valve 7 is made conducting and applies a moderately negative bias from the section 28-27 of the battery, the valve 6 being extinguished by means of a commutating condenser 24. Finally during the non- conductive half cycle of the main device the valve 8 is made conductive and applies a large negative bias from the section 29-27 of the battery, the valve 7 being commutated by a condenser 25. By this means the disadvantages due to having a large negative bias at the beginning of the negative half cycle are avoided, whilst the large negative bias at the end of the negative half cycle prevents premature ignition. Back ignition protection is obtained by means which applies a negative potential to the grid of valve 6 or if desired to the grids of all the auxiliary valves when back ignition occurs.
