Abstract: 1,228,685. Rollers. GENERAL FOODS CORP. 25 July, 1969 [2 Aug., 1968], No. 37608/69. Heading F2U. A cradle C for applying a sheet (e.g. a negative) to a roll 10, e.g. a printing roll, comprises a frame 19. . . 21 having a support 22, 23 shaped so that when resting on the roll it positions a longitudinal axis (normal to the Figure) of the frame parallel to the rotational axis of the roller, and an aligner (e.g. a plate 66 with pins 65 to locate in holes in the sheet) on the frame to align a transverse dimension (e.g. the leading edge 80) of the sheet parallel to the axes. The sheet may be attached to the roll 10 by a length of tape T with pressure adhesive on both sides. When the sheet is in the position shown a roller 50 in the frame may be lowered by rotating a hand wheel 58 to rotate an eccentric 57, and pins 65 removed, and then the roll 10 may be turned clockwise to draw on the sheet from a support 66. This may pivot about an axle 69 with an arm 71 clamped at 75. The cradle may be supported by a structure Figs. 1 and 2 (not shown) including pulleys 33 for a counterweight 34 and an arm 41 pivotable to move the cradle, the structure supporting two rolls 10 end to end, which can be rotated by a geared down electric motor, and also adjusted axially.

Abstract: 1,231,658. Heptenes. ESSO RESEARCH & ENG. CO. 12 Jan., 1970 [14 Jan., 1969], No. 2224/69. Heading C5E. Heptenes are produced by subjecting a feed comprising propylene and iso-butylene dimer to elevated temperature and pressure in the presence of a polymerization catalyst wherein dissociation of the isobutylene dimer is effected before any appreciable polymerization is allowed to take place. A preferred catalyst is phosphoric acid on a support. The retardation of polymerization may be effected by deactivation of the inlet portion of the catalyst, e.g. by absorption of a base such as NH 3  or a volatile organic amine, or by replacing the inlet portion by a cracking catalyst such as Al 2 O 3  or SiO 2 - Al 2 O 3 . The feedstook may be diluted with propane.

Abstract: 1,252,901. Cutting glass. PILKINGTON BROS. Ltd., F. J. GROVE, D. C. WRIGHT, and F. M. HAMER. 21 March, 1969 [29 March, 1968], No. 15302/68. Heading C1M. Glass is cut along a predetermined cutting line by subjecting the glass to a high frequency electric field through its thickness so as to heat the glass and set up stress and so as to cause a controlled fracture to run along said line. The fracture is generally started from a weakened point in the glass, e.g. a score mark, and if the stress is insufficient to complete the fracture a mechanical force may be applied to separate the glass. Glass sheet 1 may be cut transversely, using apparatus comprising two electrodes 4 and 5, 4 being in rectangular plate form and 5 a rod lying parallel with the plate (4 and 5 may be of aluminium) and a high frequency generator 7 whose output may be varied. The glass may be cut transversely while moving, e.g. from a float process or a vertical draw process, in which case the electrodes are arranged to move at the same rate as the glass. Alternatively the glass may be cut in a direction parallel to the direction of travel, in which case the electrodes are maintained stationary and the power output is regulated to hold the fracture-head substantially constant relative to the electrodes. This technique may be employed in trimming the margins of a ribbon of glass. Stacked glass sheets may also be cut by the invention. Glass supported on an air cushion may also be cut. Shaped articles may be cut from a sheet by using one electrode in the form of a plate and the other in the form of a plurality of insulated electrode parts which are arranged in the profile of the desired article, and which may be energized in sequence. Alternatively both electrodes may be shaped to the profile of the desired article.

Abstract: 1,264,271. Welding by pressure. WESTERN ELECTRIC CO. Inc. 6 May, 1970 [7 May, 1969], No. 21774/70. Heading B3R. In a method of simultaneously bonding metallic wires to spaced regions on one or more substrates, a wire 20 is wound about and secured to a compliant member 19, the latter and the wire is severed to leave wire portions 21 secured to the compliant member and to deform the member and wire to produce visible marks 24 which are then used to align the wire portions with the regions. As shown, electrical leads to be bonded to spaced conductive lands on an integrated circuit substrate are formed by winding a gold filament 20 about a compliant support 19, which may comprise a strip of aluminium foil having a surface oxide, or PTFE. The support can have edge notches 23 to locate the turns of the filament. An adhesive tape 22 or an insulating varnish is used to secure portions of the filament to the support 19. Edge portions of the latter, including portions of the filament thereon, are removed as along lines a, a to leave a number of spaced conductors 21 (Fig. 3a) on the support. During the edge portion removal operation visible marks 24 are formed on the support. Using these as guides, the conductor end portions are placed in overlapping relation with the lands (13) (Fig. 4, not shown) and bonding energy applied through the support. The energy can be in the form of ultrasonic or acoustical vibrations and/or heat and pressure. During bonding, an end portion of each filament, bonded to respective lands, is slightly flattened. The lands can be gold-plated. In modifications (not shown), the edge notches 23 are replaced by apertures adjacent the edges, the filament being threaded therethrough; and the inter-turn distances are non- uniform and/or in different configuration(s) from that of the above description. Specification 1,239,631 is referred to.

A similar auxiliary " deflection " electrode 10, 11 may be positioned adjacent to the anode and likewise separated therefrom by a layer of insulating material, the deflectionelectrode being maintained at a potential less positive than that of the anode and preferably equal to that of the cathode. In the arrangement shown the layers of insulating material 2 are regions of a gas discharge tube of rectangular cross-section, the anode and cathode 4, 3, spaced counter-electrodes 6, 7 and spaced deflection-electrodes 10, 11 extending longitudinally of the tube.

The brush 4 is mounted on the end of a rod 6 with the interposition of a resilient washer 5, the rod 6 passing through an aperture in an upper projection 7 of the brush holder which also acts as a stop for the brush spring 8. An insulating sleeve 10 surrounding the brush holder 1 screws into the current supply bar 11 to press a shoulder 3 of the brush holder against a corresponding shoulder of the bar 11 by means of a resilient annular member 12. The insulating brush raising member 13, which is of square cross-section, is freely received within a generally square bore formed by the end of the sleeve 10 and is slidable on the rod 6, normally being urged against the projection 7 by a spring 14 which is weaker than the spring 8. To raise the brush, the member 13 is lifted out of the end of sleeve 10, and then rotated so that, under the force of spring 8, it will abut against the end of the sleeve. This action lifts the brush 4 away from the surface 9, so that the whole assembly may now be unscrewed from bar 11. Abutment of a block 15 on the end of the rod 6 against the bottom of member 13 prevents the brush being worn away too far, the block 15 also providing, by its position at any time, an indication of brush wear.
