Abstract: 1,237,085. Welding by fusion. BRITISH SHIP RESEARCH ASSOCIATION. 29 Oct., 1968 [15 Nov., 1967], No. 52089/67. Heading B3R. A method of joining metal plates, e.g. by submerged arc welding, includes the steps of magnetically gripping adjacent edges of the plates and effecting relative movement of the gripped edges to bring surfaces of the plates into alignment, the weld being made from one side only. Apparatus for use in the method comprises a pair of gripping devices for gripping adjacent edges of a pair of plates 22, 21, each gripping device comprising magnet means 10, and means for effecting relative movement of the gripping devices to align the surfaces of the plates. In one embodiment (as shown) scissors jacks support a pair of beams 11 for vertical movement between plates 12, the beams mounting a plurality of spaced magnets 10. The gripping devices are surrounded by a concrete bed 24 (Fig. 6) provided with castors which enable the plates to be positioned easily. The bed is provided with sockets for side stops to retain the plates laterally in position on the bed. Retractable centre line stops 26 are provided to enable the correct positioning of one of the plates above one of the gripping devices whereupon the plate is gripped, and the stops 26 moved into a retracted position (not shown) to allow the other plate to be brought up to the first, and gripped. Vertical movement of one gripping device is then effected to align surfaces of the plates. In a second embodiment (Figs. 7-11, not shown), raising of the gripping devices is effected through sets of wedge devices (48, 49), operated by hydraulic jacks. The bedplate of the gripping devices may be constructed in sections bolted together. During welding of the plates the weld pool may be supported by backing flux held by a pneumatically inflatable support, a copper backing bar, or a water-cooled backing bar.  Modifications include the replacement of the castors by driven rollers, and the stops may be electrically or mechanically retractable. Start and run-off plates may be welded to the plates prior to their welding.

Abstract: 1,085,580. Feeding webs. AERO ZIPP FASTENERS Ltd. Dec. 24, 1965, No. 54765/65. Heading B6B. [Also in Division D1] As a strip, web, tape, cord or string 19 is drawn over a pulley 21 by conical rollers 1 and 2, its tension exerts a force on the pulley 21 mounted on a pivoted arm 23 having a counterweight 26. If the tension varies, the position of the strip 19 on the roller 1 is correspondingly varied to return the tension to its initial predetermined value which is determined by the weight of the counterweight 26 and its distance from the pivot axis 25. The pivoted arm 23 and counterweight 26 may be replaced by a spring and a suitable guide for the pulley 21. Two such feeding arrangements as described above are positioned at the entry and exit to a treatment tank 36 (e.g. a soaping tank in a dyeing machine), the two sets of conical rollers being driven at the same speed by a common drive transmission. If shrinkage is present, one set of rollers may be driven faster than the other, or the rollers given different diameters and rotated at the same speed. The feed cores may comprise a resilient material such as rubber.

Abstract: 1,150,378. Television; interference suppression. RANK ORGANISATION Ltd. 27 Nov., 1967 [8 Dec., 1966], No. 55120/66. Headings H4F and H4L. To reduce the noise level during the blanking periods of a composite television video signal, the bandwidth of the composite signal is reduced by means of a switch and a filter only during the blanking periods. In a first embodiment, Fig. 1, a composite video signal from a mixer 6, supplied from a video signal generator 2 and a line and frame blanking signal generator 4, is applied to the input of a two-gang switch 8 arranged to pass the blanking signal pulses of the composite signal along path I which includes a filter network 12, and the remainder of the composite signal along path II. The resulting signal may be passed to a clamping circuit 10 the operation of which is improved due to reduction in the noise level caused by the reduction of the bandwidth in the blanking signal periods effected by filter 12. In a second embodiment, Fig. 2, the composite signal is passed via impedance 14 to the clamping circuit 10, switch 8 being operative only during the blanking periods to connect shunt capacitor 16 into the signal path, thus integrating the noise and thereby reducing the level thereof during the blanking periods.

When the voltage of source 12 falls below a predetermined value, a relay 14 actuates its contacts 13, 15-18 to operate members 20, 23, 25, 26, 31 as an inverter and so supply the load 11 through a filter 21. The charger drive circuit 24 and inverter drive circuit 41 are conventional and are isolated by diodes 37-40, respective pairs of which each form an OR gate. When charging battery 20 the voltage across transformer taps 27, 36 or 28, 35 is applied to members 25, 34 or 26, 33, and rectifiers 25, 26 pass current pulses whose duration and magnitude are determined by the difference in phase between the firing pulses from circuit 24 and the A.C. across the winding 30. During inverter operation diodes 33, 34 protect the rectifiers 25, 26 from high reverse voltages, these rectifiers being turned off by a commutating capacitor 52 whose charging rate is reduced by the inductor 31.
