Abstract: 1,008,356. Printing surfaces. C. TINLING & CO. Ltd. Nov. 28, 1961 [April 20, 1961], No. 14228/61. Heading B6C. A method of manufacturing a plastic-backed printing plate having a type face consisting of a metal shell bearing the printing indicia, includes the step of forming the rear face of the shell with an irregular or roughened surface which constitutes a key for a subsequently applied backing of a synthetic thermosetting resinous material. A copper shell 12 is produced electrolytically on a mould 10 of a thermosetting material and the rear face 14 of the shell is roughened by placing the mould in a copper sulphate solution containing copper dust in suspension and by electrolysis causing copper dust to be deposited on the rear surface of the shell, Fig. 2 (not shown). Alternatively, the face 14 may be simultaneously sprayed with copper dust and an adhesive such as sodium silicate, Fig. 3 (not shown). The face 14 is then coated electrolytically with a further layer of copper which retains the copper dust in position. The copper dust may alternatively be sprinkled on to the shell. An assembly comprising thermosetting resinous powder 32, paper sheets 34 and 40 impregnated with a thermoplastic or thermosetting resin, a sheet of synthetic rubber 36, and a perforated zinc plate 38 is then placed as shown on the roughened rear face of the shell and is cured under heat and pressure.

Abstract: 774,278. Centrifugal moulding of micaceous material. EICHENAUR, F. May 21, 1953 [May 29, 1952 ; March 26, 1953], No. 14285/53. Classes 70 and 87(2). Apparatus for the production of a number of mica insulating members by centrifuging a suspension of mica particles comprises a screening drum having projections on its internal circumferential surface, the projections being arranged to divide a layer of mica precipitated on the internal surface into separate members and to form apertures in the members. A perforated drum 28 rotated by a motor 25 is mounted within a stationary casing 22 having an outlet 24 for centrifuged liquid. The circumference of the drum is lined with screening' sections 31 having projections 34, 36, 37 which respectively divide the precipitated mica into insulating members 39, form apertures in the members, and form depressions in the members. In modifications dispensing with screening sections, the projections may be formed by deforming the wall of the drum or by vulcanizing rubber elements to the inner surface of the drum. The members are centrifuged from mica suspension without binding agents and are thereafter dried. The members are then treated with binding agents and subjected to small modifications in shape.

The bottom blank is separated by the usual suction separator (not shown) and rotating gapped discs 5, and withdrawn from the pile by two rotating segments 6 and co-operating rollers 8. As the bottom blank is withdrawn, the rear edge 38<SP>11</SP> of its window opening is deflected below the leaf springs and hence prevented from engaging the front edge 38<SP>1</SP> of the window opening in the superposed blank. After the rear edge 38<SP>11</SP> has moved past the superposed front edge 38<SP>1</SP>, the leaf springs are withdrawn at high speed to free the bottom blank for complete withdrawal. Each leaf spring moves in a guide block 32 secured to a support 35. Each guide block is cut away centrally to provide a guide surface 29. A freely rotatable roller 31 is mounted in said cut-away portion.

Abstract: 1,014,640. Knitting-machines. TEXTILE MACHINE WORKS. April 9,1964 [April 12,1963], No. 14749/64. Heading D1C. In a mulfifeed circular knitting machine pivoted selector levers 20 operate on frangible butts 16 of rocking jacks 14 for needle selection each selector lever being formed with two nose portions to read a pattern drum and a control drum. During normal operation the nose portion 19 of the levers read the butt pattern of the pattern drum 21 which is moved by a pawl 25 from the main cam shaft of the machine. The control drum however controls an arm 130 Fig. 2 (not shown) which carries a downwardly extending bent rod 131 to move the pawl out of operation and hence stop the movement of the pattern drum 21. The pattern drum 21 is driven, through the pawl 25 from link 41 forming part of a bell and crank lever which is driven from an eccentric 55 and this bell crank lever may be locked in the position corresponding to the high part of the eccentric by a lever 67 which is controlled by a Bowden cable from the main cam as shown in Fig. 6. A single lay out lever 95 is provided to move all the selectors to their machine positions but the control drum 97 is also used to move selected single levers to their machine positions. The cam drum 92 moves through one complete cycle for each stocking knitted but the control drum 97 moves through only one complete cycle for every four completed stockings. For the formation of 3 x 1 pattern of tuck stitches eight selectors read the butt pattern of the trick drum 21 and the butt pattern of one segment of the control drum may be set up to activate the eight selectors to form this pattern, and subsequent segments may be set up to vary the normal 3 x 1 pattern in spaced portions of the leg patterns or throughout the leg pattern in each of the other stockings.
