Title: Method of continuously treating the surfaces of the edge portions of metal sheets
IPC: C25D7/06

Abstract: 1,201,935. Coating apparatus. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 19 Sept., 1967 [30 Sept., 1966], No. 42688/67. Headings B2E and B2L. [Also in Divisions C6 and C7] The surface of the edge portions of a metal sheet 1 are continuously treated by moving the sheet longitudinally whilst having its edge portions immersed in a surface treating liquid 3 flowing down confronting faces of vertically positioned wall structures 2. As shown the fluid 3 flows from upper containers 4, down the surface of the wall structures 2 to collect in containers 5. The treatment may comprise cleaning, etching, polishing, coating, colouring, plating or anodizing, and the metal sheet to be treated may be iron, copper, aluminium, tin nickel or an alloy thereof. For electrolytic treatment, the walls 2 should form the counterelectrodes, and may be of graphite, e.g. with a layer of porous non-conductive material attached thereto to prevent short-circuit therebetween. .

Abstract: 1328761 Control circuits for flash discharge apparatus FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE] 14 Sept 1971 [14 Sept 1970] 42846/71 Heading H2H Flash discharge apparatus comprises a thyristor 2 connected to a storage capacitor 3, a discharge thryistor 9 connected in parallel with the capacitor, a voltage indicator 10 which can be adjusted to vary the capacitor voltage and a thyristor 6 for quenching the discharge thyristor. If the pro-selected capacitor voltage, determined by adjusting a potentiometer 4, is less than the existing capacitor voltage, the indicator 10 triggers the thyristor 9 so that the capacitor 3 discharges via a resistor 8 until the voltage falls to the pro-selected value. If the pre-selected voltage exceeds the existing capacitor voltage, the indicator 10 triggers the thyristor 2 to enable charging of the capacitor and also the thyristor 6 to quench the thyristor 9.

Abstract: 1370142 Combined drum and full-face disc brakes EATON GmbH 15 Sept 1971 [12 Oct 1970] 42964/71 Heading F2E In a combined disc and drum brake 1 in which the disc brake 2 is hydraulically actuated and the drum brake 3 mechanically actuated, separately or in unison with the disc brake, pivot pins 17 serve to guide axial movement of a disc 15 and through bushes 19 support and provide pivot points for the shoes 21 of the drum brake. The disc 15 is moved into contact with a friction lining 4 on a wheel 5 by means of an annular piston 14 slidable in a brake housing 10. Mechanical actuation is provided by an operating lever 30 mounted on a pivot pin 18 and connected to a cam sleeve 29 for spreading the brake shoes, which sleeve is mounted in a bush 28 of housing. A leaf spring 32 is attached to the lever 30. When the friction disc 15 is actuated, pivot pins 18, sleeve 29 and lever 30 are forced to follow the movement. As the wear increases lever 30 and leaf spring 32 move nearer to a rim 36 of wheel 5 until a leaf spring end 32b rubs against rim 36 thereby indicating the allowable degrees of wear in the disc brake. When lever 30 is turned, thereby turning sleeve 29, shoes 21 are spread and friction linings 20 pressed into engagement with rim 36. As linings 20 wear the sweep of lever 30 increases until the leaf spring end 32a engages a control stop 35 indicating the permissible degree of wear. In a further construction an electric switch (40), Fig. 5 (not shown), is provided and lever 30 has a conical cam in the axial direction and a curveshaped cam in the radial direction which actuate the switch when permissible wear of the disc brake 2 and drum brake 3 respectively is attained.
