Title: Fluid pressure fittings
IPC: F16J15/08
Filed: 1964-02-05
Abstract: 1,009,682. Pressure fluid couplings; stuffing- box packing. L. & L. MANUFACTURING CO. Feb. 5, 1964 [June 5, 1963], No. 4980/64. Headings F2B and F2G. A pressure fluid coupling comprises a connecting member having a cylindrical surface, a split resilient sealing ring of substantially circular or elliptical cross-section which is loosely received coaxially on the cylindrical surface and a part included in the connecting member having a circumferential abutment surface, this part being movable axially with respect to a bore into which the connecting member is adapted to be fitted and the entrance of which is bevelled, so that the abutment surface contacts the split sealing ring and forces it into sealing engagement with the bevelled surface. A connecting member 26, Fig. 1, is screwed, by its thread 28, into the member 20, the screw-threaded bore 22 of which is, at its entrance, bevelled at 24. A nut 34 screws on to the bored connecting member 26, which is screw-threaded at 36 for the purpose, and between the threads 28 and 36 is an unthreaded portion 30, embraced by a loosely-fitting split metal sealing ring 42. A tapered annular groove is formed into which the ring 42 is forced and is contracted till its split is closed up. At this stage a small clearance 44 still remains between the ring and the plain portion 30 and this is filled by elastic deformation of the ring on further tightening of the nut 34. In Fig. 4 the member 20a has a plain bore with its entrance bevelled at 24a and a member 23 enters the bore and has a portion 30a, between two flanges 32a, 28a, the latter being tapered to allow a split metal sealing-ring 42a to be forced over it, the ring 42a then fitting loosely around the portion 30a. A nut 90 has a flange 92 which fits behind the flange 32a and has a screw thread 29a which coacts with a threw thread 22a on the member 20a. As the cut 90 is screwed towards the member 20a the ring 42a is first contracted and then elastically deformed, as is the ring 42 in the first embodiment. The nut 34 or the nut 90 could be integral with the remainder of the connecting member, in which case sealing would be effected by axial movement into the bore of the connecting member as a whole. Preferred cross-sections for the ring 42 are shown in Figs. 7, 8 and 9. In Fig. 7 the section is approximately elliptical, the major axis A being intended to be parallel to the axis of the bore of the coupling, but the sides are slightly flattened at 48, 50. The ratio of the length of the minor axis B to the length of the major axis A can be between the values of 0À25 and 1, 0À7-0À85 being especially suitable. The cross-section shown in Fig. 8 has a flattened peripheral part 56 and parts 60, 62 formed with large radii of curvature. Fig. 9 shows a cross-section approximately the same as that of Fig. 7 but with a groove 66 which is adapted to engage the threaded portion 28, Fig. 1. The rings may be made by coiling wire into a helix and cutting portions of the coil, the cut ends being given surfaces each lying in a radial plane of the ring.

Abstract: 1,262,153. Television; multiplex radio signalling. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 29 Jan., 1969 [2 Feb., 1968 (3)], No. 5041/69. Headings H4F and H4L. Facsimile signals are superimposed upon a television signal in the vertical blanking periods preferably after the second group of equalizing pulses, and at a television receiver the output of the video amplifier in addition to being applied to the receiver's display CRT is also applied directly to a facsimile CRT which is rendered operative i.e. unblanked, during the occurrence of the facsimile signals, the television CRT being then blanked. The same horizontal and vertical deflection circuits and the same high voltage supply circuit are connected to both CRT's. The facsimile CRT comprises a line scan CRT e.g. a pin or optical fibre tube, the resulting line display being recorded on a recording paper sheet which is intermittently moved one line width per television field i.e. one line of the facsimile signal is transmitted during the vertical blanking period of each television field. Instead of each line of the facsimile signal being spread over three horizontal line periods in the vertical blanking period as in the described prior art, it is arranged to occupy only one horizontal line period so that the horizontal deflection circuit current for the television display CRT may be applied directly to the facsimile CRT horizontal deflection coil.

IPC: B31B50/72
Filed: 1963-02-07
Abstract: 1,075,691. Laminates and laminating; making flat laminated bags. PLASTIC TEXTILE ACCESSORIES Ltd. Jan. 30 1964 [Feb. 7 1963] No. 5057/63. Headings B5D and B5N. [Also in Division B8] Bag making material is made by feeding tubular plastic material along a linear path, reversing the direction of feed by turning the tube inside out, feeding a second tubular web over the first while travelling in the reverse direction, hot-sealing the tubes together in narrow areas spaced apart around their circumference, and cutting them into flat tubes along the median lines of the sealed areas. The originating tubes may be of different plastic materials or of different structure, e.g. the materials may differ in transparency, opacity, colour, thickness, pattern or printing, or one of them may be of perforated or reticulate form. in which case sealing is effected by strips fed over the reticulate or like material and heatsealed to the other layer through the meshes. The non-netted material may be embossed. The number of sealing areas may be two or three and these may be arranged symmetrically around the tubes, or asymmetrically to produce bags of different widths. As shown, a flattened tubular plastic web 2 of net structure is fed from a reel 1 to rollers 4 and to a rectangular ring 7 of rounded cross-section where it is reversed in direction and fed to pairs 13, 14 of co-operating belts. Strips 8 of plastic material are fed from reels 81, pass around rollers 9 and move forward outside, and on reversal inside the tube 2. A second flattened tubular web 11 of plain plastic material is drawn from a reel 10 over the ring 7 and between the belts 13, 14. Narrow heated pressing members 15, 16 seal the strips 8 to the web 11 through the meshes of the tube 2, the seals are cooled by air jets 17 and the combined tubular material is slit by knives 18 into flat edge-sealed two-layer material from which bags may be made. The web 2 may be plain and 11 netted, in which case the strips 8 are fed over the latter web.
