Title: Electrical connectors
IPC: H01R4/24
Filed: 1976-01-26
Abstract: 1519769 Electrical connector POST OFFICE 26 Jan 1976 [18 Nov 1974] 49878/74 Heading H2E An electrical connector comprises a first member at least partially received within a second member for relative rotation about an axis of rotation, said first and second members being infixed axial relationship and having respective first and second opposed surfaces one of which is contoured so that, when a conductor is inserted between the surface portions, relative rotation of the members causes the conductor to be drawn further into the connector in a direction substantially parallel to said axis of rotation, the member which has the contoured portion being electrically conducting. In the embodiment shown, an electrically conducting cylindrical member 3 is threaded, an outer member 2 having tapered recesses 7 which may each receive a conductor 8. A circlip 5 is received in a groove 4 at each end of member 3, portions 6 of the circlip abutting the end faces of member 2 without obstructing the end entry opening of each recess 7. An end of the threaded member may be provided with a screwdriver slot 11, may be knurled, or may be formed with wings in the manner of a wing nut. In a second embodiment (Fig. 4, not shown), relative axial movement of the members is prevented by a projection (18) of theoutermember snap-engaging in a recess (17) of the threaded inner member, the recess separating threaded portions of opposite hands. Thus, since aligned recesses (7b) extend from each end face of the outer member, conductors may be drawn into the connector simultaneously from both ends thereof. In a third embodiment, a terminal (Fig. 3, not shown) has an outer conducting threaded member, an inner member being provided with tapered recesses for receiving the conductors.

Abstract: 1,163,286. Ornamenting. E. I. DU PONT DE NEMOURS & CO. 8 Nov., 1966, No. 49900/66. Heading B6G. [Also in Division C1] A non-porous metal substrate carrying within its surface a particulate material consisting of glass, a glass-metal mixture, or a glass metal composite, the particulate material being impressed into the substrate to a degree such that it is firmly embedded therein with its outwardly facing surfaces substantially coplanar with the surface of the substrate, is produced by heating the glass or glass-metal to a temperature at which the glass viscosity is in the range 10<SP>2À8</SP>- 10<SP>7</SP> poises, then the metal in the glass-metal mixture to sintering temperature, finally the metal substrate to a temperature at which its surface becomes soft enough to accept the particulate material when compressive force is applied, then, before substantial cooling occurs applying the compressive force to the particulate material and to the metal substrate with the particulate material distributed over it, and then cooling the metal substrate with the particulate material embedded therein. Both sides of a metal substrate may be so coated, or the same or different coloured glass compounds may be applied by superposing a plurality of layers one over the other as by a silk screen process, each being hot-rolled. The three heating steps may be applied in sequence or, when their temperatures overlap, concurrently. Suitable metal substrates are aluminium, magnesium, zinc, and alloys thereof, low carbon steel, stainless steel, copper, nickel, titanium and alloys of copper, nickel or titanium. In a typical example (1) a lead borosilicate glass containing iron cobalt black sintered inorganic pigment (viscosity 10<SP>4</SP> poises) ground to a fineness of 100% through a 100-mesh screen is applied with methanolthinned epoxy-resin adhesive on an aluminium substrate and heat-rolled immediately at 580 C. In Example 5 glass decalcomania in the form of an antique automobile design is applied to an aluminium sheet, the maturing temperature of the glass being 540 C. at which the viscosity is 10<SP>4</SP> poises, the decalcomania being applied to the metal substrate, heated to a temperature of 580 C. and immediately hot-rolled. In Example 5a a similar decalcomania is applied to a metallic nickel strip, heated to 800 C. for 10 mins. and immediately hot-rolled.

Title: Nonwoven thermoplastic fabric
IPC: A61M5/00
Filed: 1973-10-26
Abstract: 1453447 Laminated non-woven material KIMBERLY-CLARK CORP 26 Oct 1973 50041/73 Heading B5N A non-woven material comprises a web of continuous, randomly-deposited, molecularlyoriented thermoplastic polymer filaments bonded to a mat of discontinuous thermoplstic microfibres of average filament diameter up to 10 microns at a number of discrete areas. The fibres and filaments may be of polypropylene, polyethylene, polyamide, polyethylene terephthalate or polyurethane and may be pigmented; in examples the web is of polypropylene and the mat is of polypropylene or polypropylene-nylon blends. The mat is formed by attenuating polymeric filaments and collecting the resultant fibres, which are of diameter less than 10 microns and of longer than staple length, to form an integral structure. The web is formed by drawing extruded filaments of diameter 12-55 microns and depositing them to form an unbonded structure. The web and mat may be laminated by passage between rollers to consolidate the web and then between heated rollers, one of which has a raised pattern (which may be formed by the crossovers of a grid), for bonding. Preferably the mat has a softening point 10-40 C. below the web and is in contact with the non-patterned heated roller before passage through the nip so that bonding is assisted by the softening of the microfibres and the web filaments are not substantially fused. The bonding points may occupy 5-50% of the surface area at a density of 50-1000/in.<SP>2</SP>. Alternative bonding methods use adhesive or needling. Mat - web - mat and web - mat - web laminates may be produced. The mat : web weight ratio may be 0À2-4 : 1. The product may be used as a fabric for garments, a wiping cloth or as a surgical wrapper and is breathable and water-repellent. Some products absorb liquid in the mat while leaving the web comparatively dry and are useful as wash cloth/ towel combinations.

Abstract: 1444813 Crimping yarns MONTEDISON FIBRE SpA 29 Oct 1973 [27 Oct 1972] 50267/73 Heading D1F In the operation of a device for continuously crimping synthetic, thermoplastic, continuous filament yarn, rotation of a cylinder 4 relative to and within an outer member 1 causes hooks 6 to slide in channels 7 as a result of engagement of hook bases 6B with a continuous groove 5. Thus, as each base travels along one arc BA the hook-end projects beyond the end of the cylinder, as at 6y, whereat it catches the (preheated) yarn; travel along an oblique portion AD of the groove causes the hook to retract to a position, as at 6x, whereat the entrained yarn is deformed by engagement around, and to a wave form determined by the shape of, the exposed ends of projections 9; during travel of each base through arcuate portion DC the hook holds the yarn so that it is set by cooling (which may be enhanced by injected fluid e.g. air); finally in the travel of base 6B in the oblique portion CB, the hook is advanced, as at 6z, beyond the cylinder end whereat the crimped yarn is released for takeup. The hooks are retained in the channels by the inner face of member 1 and a spring 8 housed in a peripheral cavity 10. In a continuous process, Fig. 4 (not shown) undrawn as-spun filaments/yarn may be drawn and/or heated by sliding contact with a hot surface immediately before entering the crimping device.

Abstract: 1535761 Automatic steering control system KOCKUMS AUTOMATION AB 9 Dec 1975 [11 Dec 1974] 50412/75 Heading G3N An automatic steering system enables a ship or aircraft 20 to follow a circular or eliptical path 13 of predictable radius in changing from one course 10 to another 11. The set radius R b  is determined using a model, either on a chart by a caliper or yaw lay-outs or by a display unit 22 with a radar PPI (plan position indicator) image. The actual instantaneous radius Ra = V/Wa where V is the vessel speed and Wa is the angular speed, both being determined by instruments aboard. A difference signal is then generated which can equal R b -R a , (R b <SP>-1</SP>-R a <SP>-1</SP>), (W b <SP>-1</SP>-W a <SP>-1</SP>), or (V-R b W a ), and this is used to control the rudder 21 either automatically or manually 31, to decrease the difference. Unit 32 displays, using analog digital or hybrid techniques, yaw Figs. 7-9 (not shown), using using light emitting diodes or liquid crystals. The path speed V is determined by a one or two component pressure or Doppler log 27 using a computer, or by computer calculations based on determining the distance and direction of fixed points. The angular velocity Wa is determined using an auxiliary gyro 28.

Abstract: 1,092,749. Moulding lenses &c. PITTSBURGH PLATE GLASS CO. Nov. 30, 1965 [Dec. 1, 1964], No. 50664/65. Heading B5A. In a method of producing thermosetting resinous articles, e.g. lens, a mould is produced from a master pattern of the article by casting a thermo- , plastic resinous material about the pattern removing the pattern and introducing a thermosetting resinous material into the mould, heating the filled mould to cure the thermosetting material and separating the cured article from the mould. A glass lens 20 may comprise the master pattern which is placed on a ring holder 25 located within a mounting ring 22. Polyethylene is poured into the ring and forms the male section of the mould; the female mould part is similarly produced after inverting the lens and mounting ring, and placing the lens on a support which locates it centrally of the ring. The female mould part (31), Fig. 12, not shown, is located in a ring (40), and its cavity supplied with thermosetting resinous moulding material, e.g. allyl diglycol carbonate to which a catalyst has been added. The male mould part 30 is then placed in position and the assembly subjected to a curing cycle. The mould may be melted down and re-used. The material of the mould and article are so matched that the mould material is relatively rigid during initial curing and becomes progressively softer so that surface stress on the article is obviated and the mould follows the curvature of the shrinking article.

Abstract: 1406577 Cathode-ray tube displays N K BUSHNELL 1 Now 1973 [24 Nov 1972] 50771/72 Heading H4T In a cathode-ray tube display system in which an image is produced on a raster scanned display tube 11 by "video" type information signals generated on coincidence of predetermined counts in horizontal and vertical image locating counters 23 and 24 respectively the position of the image may be changed by introducing differences between the counts produced by the latter counters and the counts produced by horizontal and vertical synch. counters 14 and 19 respectively. The horizontal synch, pulses 16 are produced by counter 14 which is pre-set by one count so that pulses 16 are produced after a count of 255 pulses from the 6 MHz clock 12. Pulses 16 are then counted by counter 19, also preset by one count, so that vertical synch, pulses 21 are produced when counter 19 has counted 255 of the pulses 16. Counter 23, normally produces an output pulse 27 when it has counted 256 clock pulses and counter 24, normally, produces an output pulse 31 when it has counted 256 of the pulses 27 coincidence of pulses 27 and 31 forming via AND gate 37 the "video" information which produces the image. To vary the displayed position of the image manually controlled preset selectors 38, 43 allow pre-set counts to be set up in counters 23, 24 so that the output pulses occur at selected time positions relative to the scanning of the raster. When the image movement is to be confined to a single axis switch 25 is operated to replace pulses 27 by pulses 16 as input to counter 24 so that there is no relative displacement between the counts in counters 16 and 24. However pre-set selector 43 may still introduce movement of the image. The invention has application to entertainment devices in which the position of the image is controlled by "players".
