Abstract: 883,942. Photoetching materials. RADIO CORPORATION OF AMERICA. Feb. 24, 1958 [March 1, 1957], No. 5971/58. Drawings to Specification. Class 98(2). A sheet as of silver or copper having a .photosensitive surface portion, or else a sheet of photosensitive glass, is characterized by a coating of insulating material which may have a finely divided photoconductor dispersed therein on the photosensitive surface; and use thereof comprises charging the insulating coating, projecting a light image thereon to form a complementary electrostatic image, forming a powder image corresponding thereto, exposing with light to which such powder image is opaque to harden the photosensitive surface imagewise, removing the powder image and the insulating coating, and subsequently etching through the hardened image. Typographic, lithographic or gravure printing plates or printed circuits may result from such use. In an embodiment of the invention the metal surface of a copper-clad phenolic resin sheet is coated with a specified glue-albumin-bichromate solution, dried, overcoated with a silicone resin containing zinc oxide in toluene, the latter is evaporated and a corona discharge is applied in darkness, the metal being grounded; a light image from a 35 mm. transparency is then projected on to the charged surface to leave the charge only on the dark areas, and a mixture of magnetic particles with opaque powder is applied thereto; exposure is then made from a mercury vapour lamp, the powder mixture is removed with a magnetic brush and the silicone coating with toluene, after which unhardened areas of the bichromate layer are removed with warm water, the remaining areas baked and the metal etched. In a further embodiment a perforated template is placed in contact with the insulating coating and the electrostatic charge pattern formed directly through the holes of the template.

Abstract: 1459931 Tyre shaping drums UNIROYAL Inc 12 Feb 1974 [16 Feb 1973] 06327/74 Heading B7C A tyre carcass shaping drum comprises two axially movable coaxial units 11, 11a each unit comprising a plurality of circumferentially spaced, pivotally mounted, substantially axially extending fingers 21, (21a), a sleeve 15, (15a), anchored at its axially outer edge to the fingers and means for pivoting the fingers between a radially retracted position and a radially expanded position. In the illustrated drum the axially inner edge of each sleeve is anchored to a member 37, (37a) of the unit and the means comprises a piston actuated cam arrangement 12. The application of a fluid e.g. air to chambers 33, 33a causes annular pistons 31, 31a to move against bias of springs 36, 36a and cam rollers 29 carried thereby engage surfaces 24 of pivoted arms 22. As each arm 22 is pivoted against bias of circumferential spring 28, cam rollers 25 each engage a respective finger 21 and pivot that finger against bias of a further circumferential spring 45. In this position the beads 13 of a tyre carcass will be securely held by the fingers and movement of the units away from each other will cause the beads to sealingly engage the sleeves (Fig. 3). Fluid, e.g. air, is now introduced into enclosed space C to shape the carcass while the units are moved together. Prior to shaping of the carcass, a previously prepared breakertread assembly removed from a drum (1), (Fig. 1, not shown), is transferred by a transfer ring (3) into a position surrounding the carcass. Pins 47, 47a which alternate with the associated fingers 21, 21a initially support the carcass beads. The members 37, 37a which pivotally carry the fingers are replaceable by other such members pivotally carrying fingers and adapted for carcasses with different diameter beads. Such replacement is effected by first removing annulus 48, releasing screws (39), (Fig. 11, not shown), and 39a which secure the members 37, 37a to the main housing of each unit, and moving the members to the left (Fig. 2). The annulus 48 and annulus 46a may also be replaced.

[Also in Division E2 and F2] A device for simultaneously releasing hydraulically controlled clamps which alternately grip and releasea cable or bar comprises a distributor controlling two hydraulic clamp releasing circuits one of which applies a small pressure force and ensures the clamps are simultaneously released only when no load is applied to the clamps. A movable clamp 155a and a stationary clamp 155b are connected to pistons 140, 143 and 146 slidable in a cylinder 136 having a partition 139. The cylinder is thereby divided into chambers A, B, C, D and E. The chamber A allows reciprocal movement of the clamp 155a along the cable or bar to drive the cable or bar as the stationary clamp alternately grips and releases the cable or bar. The clamps are simultaneously released in the absence of a load only, when the pressures in chambers B and D are greater than in chambers C and E respectively. A pressure is applied to chamberB slightly greater than that in chambers C and D and a small pressure is applied to chamber E by connecting chamber B to the distributor 330 by line 209 and pressure reducing construction to a high pressure line 189 connected to the chamber A. Chambers D and C are connected by line 205 to line 209 via a valve 331 which opens at a predetermined pressure difference. Line 205 also connects with a fluid reservoir via valve 201 which also opens at a predetermined pressure difference. The chamber E is connected to a reservoir via valve 198 or to the distributor via the valve and line 302. Under the pressure of fluid in line 302 the valve 198 is connected to the reservoir and the stationary clamp opens simultaneously with the movable clamp. Alternatively the valve 198 connects directly with the line 205 and the stationary clamp opens as the result of the difference in pressure on opposite sides of the piston 146.
