Abstract: 1,225,670. Melt spinning composite polyamide filaments. ASAHI KASEI KOGYO K.K. 20 June, 1968 [22 June, 1967], No. 29406/68. Heading B5B. Composite polyamide filaments are produced by simultaneously extruding through each orifice of a spinneret a homopolyamide melt and a copolyamide melt, the homopolyamide and the copolyamide having been raised to the same temperature in separate melting zones, the process being characterized in that the relative viscosity of the copolyamide is from 0À2 to 1À0 higher than that of the homopolyamide, the inclination of the portion of the bottom surface of the spinneret in which the outlets of the orifices are situated to the vertical axis of each spinneret orifice and the relative dispositions of the two polymer streams being such that the homo-polyamide melt stream remains longer in contact with the wall of each orifice than does the stream of the molten copolyamide. The solidified melt spun composite filaments are then stretched at a temperature between 100 C. and a temperature not less than 30 C. below the melting point of the polyamide component having the lower melting point. The term " relative " viscosity is defined as the ratio of the viscosity of a solution of 1 gram of the polymer in 100 ml. of 95À5% sulphuric acid at 25 C. to the viscosity at the same temperature of the acid alone. The spinneret assembly used may be that described and claimed in the applicants' Specification 1,225,669. The homopolyamide may be either nylon 6 or nylon 66. The copolyamide may be a copolymer of #-caprolactam and hexamethylene diammonium adipate or hexamethylene diammonium terephthalate. The copolyamide may be a copolymer of hexamethylene diammonium adipate and hexamethylene sebacate. The copolyamide may be a terpolymer of #-caprolactam, hexamethylene diammonium adipate and hexamethylene diammonium terephthalate.

Abstract: 1,226,804. Image reproduction. SYLVANIA ELECTRIC PRODUCTS Inc. 25 July, 1968 [1 Aug., 1967], No. 35597/68. Heading H4F. A picture tube 25 may be provided with signals either from a television receiver 5 or from a system 7 which develops electrical signals from photographic film. In the embodiment the photographic film is situated in a holder 53 and is scanned by a flying-spot system using a cathode-ray tube 49 operated synchronously with the picture tube 25 using operating potentials obtained from the received television signal. For colour film a signal transmitter 51 is provided having colour separation means to produce red, green and blue component signals, and a signal processing matrix 55 then obtains luminance and colour control signals at terminals A, B, C and hence at A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP>. With a switching means 21 set to position F these signals are applied to the picture tube 25. When the switching means 21 is set to position P the picture tube 25 receives the television signal from the television receiver 5, and the filmscanning cathode-ray tube also receives a disabling potential from a voltage source 45.

Abstract: 1,232,036. Two-part couplings. BENDIX CORP. 1 Aug., 1968 [29 Aug., 1967], No. 36672/68. Heading H2E. Connectors 2 and 3 comprise socket contacts 6 and pin contacts 11 respectively housed in tubular shells 4 and 8 and are locked together by three lugs 7 on the shell 4 which make a bayonet-type connection with three helical grooves 35 of six arcuate segments 34 which together form a coupling sleeve. The connectors 2, 3 may be uncoupled by reverse rotation of the coupling sleeve, or by axial movement of an outer sleeve 21 which allows the segments 34 limited radial movement so that they may pivot to disengage the grooves 35 from the lugs 7 irrespective of the angular position of the coupling sleeve relative to the connectors 2, 3. The sleeve 21 may be moved by pulling an attached lanyard 33, the force of the pull being transmitted through six circumferentially distributed springs 26 (Fig. 4), to an annular ring 27 located in an inner sleeve 12, to a bevelled flange 37 of the sleeve 12, to the segments 34 which, however, are retained by the lugs 7 on the shell 4. The sleeve 21, therefore, moves alone until its flange 45 and groove 46 engage grooves 42 and flanges 44 of the segments 34 which allows the segments 34 to move radially outwards and to pivot about integral tabs 40 located in grooves 41 in the sleeve 12. During coupling of the connectors 2, 3, rotation of the segments 34 moves the sleeve 12 relative to the connector 3 against an annular, corrugated spring 15 to provide a pressure seal between contact mounting blocks 5 and 10; an annular washer 19 preventing the sleeve 12 from moving to the right. Keys 9 extend axially from the shell 8 into complementary apertures in the shell 4 to prevent relative rotation of the shells. A rubber band 39 may be located in a peripheral groove in the segments 34 to provide resilience.

A method of bending a laminate of a layer 1 of a thermoplastic resin e.g. of polyethylene or polypropylene, with a metal cover sheet 2 e.g. of aluminium or an alloy thereof, on each side thereof comprises removing a strip 3 of the cover sheet 2 on the inner side of the corner to be formed and symmetrical about the bending line, the width of this strip being such that after the bending the free edges of the sheet left by its removal abut, pressing a heated blade into the resin along the bending line to form a groove U-shaped in cross-section with consequent displacement of some of the resin and to heat the resin and bending the laminate, the heated walls of the groove being brought into contact to weld together while the free metal edges abut against one another and shear away the displaced resin. In a preferred method, the corner formed is reinforced by sticking an angle strip of aluminium or aluminium alloy along the inner side of the bend by the interposition of a layer of adhesive or an adhesive foil.
