Filed: 1964-12-14
Abstract: 1,134,746. Moulding tubular articles. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 9 Dec., 1965 [14 Dec., 1964], No. 50796/64. Heading B5A. [Also in Divisions C1 and G6] Tubular articles comprising concentric zones of material having different properties are moulded from powdered material by first forming the zones in axially spaced relationship, secondly moving these into alignment and thirdly compressing and heating the whole to form the unitary article. In the embodiment  shown, the mould cavity for forming the outer zone A is defined by an outer annular part 1, supported by a ring 2 on a base 3, an inner mandrel 6, and upper and lower annular plungers 4 and 7. The mould cavity for the inner zone B is defined by a reduced portion of the mandrel 6, the inner surface of plunger 7, the shoulder 9 upon the mandrel, and a third plunger 10. In operation, the parts start in the positions shown in the figure and plungers 10 and 7 are lowered slightly to lightly compact the material in cavities A and B to render the material selfsupporting. The stop 5 is then removed and pressure is applied to cap 11 to push the material in cavity B into alignment with that in cavity A (see Fig. 3, not shown). Ring 2 and cap 11 are then removed and the whole placed between the platens of a press (see Fig. 4, not shown) and heated, the composite article being pressed from above by plungers 7 and 10 and from below by plunger 4. To form a nuclear fuel pellet the material in cavity A is a mixture of graphite and a binder with a fissile oxide, nitride or carbide and in cavity B is a mixture graphite plus binder. The binder may be removed during the heating and the particles sintered together or it may be hardened, and if required subsequently carbonized.

The impure n-paraffins may be produced as byproducts in the production of amines by nitration of paraffins and subsequent hydrogenation of the nitroparaffins produced or in the production of secondary alcohols via borate esters. The impure n-paraffins may be passed through a bed of alumina, silica gel or activated carbon before hydrogenation. Further hydrogenation may be carried out at 450-650‹ F. to remove olefin impurities. The catalyst may comprise Pt, Pd, Rh, Ru, Ni or Co, and optionally Re, molybdenum oxide or tungsten oxide.

Abstract: 1536286 Camera exposure indicator NIPPON KOGAKU KK 11 Dec 1975 [28 Dec 1974] 50898/75 Heading G2A A camera has indicators 4-1 to 4-n, means 2 for selectively energizing them to indicate the computed value of an exposure factor, and means 5 for selectively energizing them to indicate the actual value of the exposure factor as set by a control on the camera. As shown, a circuit 2 responsive to subject brightness, aperture value and film speed makes one of terminals 2-1 to 2-n conductive to energize one of a set of shutter speed indicating LEDs 4-1 to 4-n. A contact 5a coupled to the shutter speed setting dial (not shown) connects a pulse generator 16 to one of the LEDs to cause it to flash. The dial can then be adjusted until the LED that flashes is that energized by circuit 2. In Fig. 3 (not shown) the LED energized by circuit 2 flashes and the LED energized by circuit 5 is continuously lit. The LEDs may alternatively indicate stop values or a combination of shutter speed and stop values. The arrangement may also be used in fully automatic cameras having a manual over-ride.

Title: Pile surface materials
Inventor: PATERSON WILLIAM GILCHRIST
IPC: D04H11/00
Filed: 1963-12-24
Abstract: A pile structure comprises a foundation material and a layer of flock fibres of which at least a proportion had potential crimp which provide the structure with a pile surface and which are attached to the foundation material by means of an adhesive and which have had the potential crimp developed.  The fibres may be derived from heterofilaments defined as a unitary filament comprising two or more components arranged continuously along the length of the filament which components have different shrinkage behaviour, e.g. consisting of poly hexamethylene adipamide as one component and a poly hexamethylene adipamide-poly epsilon caprolactam or polyepsilon capro lactam as the other.  The fibres may be derived from edge crimped polyhexamethylene adipamide or polyethylene terephthalate yarns from which the crimp has been temporarily removed by heating under tension or have been subjected to a gear-crimping process.  At least 50% of the fibres may be crimped and the balance, if any, are straight and rod-like. The fibre flock may be supplied in the form of substantially straight rod-like fibres of a length preferably not in excess of 6 mm. to an adhesively coated surface of the foundation material through the action of mechanical and/or electrostatic forces, and thereafter crimping the potentially crimpable fibres e.g. by pressure and/or heat.  The foundation material may be a sheet-like body or preformed article e.g. a hat or toy, a texture fabric e.g. of cotton or other form of cellulose including regenerated cellulose, cellulose esters and ethers; silk, wool, casein, soya bean protein; condensation polymers e.g. nylon; polyesters such as Terylene (TM); addition polymers e.g. copolymers of vinyl chloride with vinyl acetate, vinylidene chloride or acrylonitrile; and glass; foamed materials, e.g. of polyurethane or plasticized polyvinyl chloride. The fabric may be coated on one side with butadiene-acrylonitrile copolymer prior to the application e.g. by spraying, of the adhesive e.g. a polyurethane.

Abstract: 1,244,347. Testing fibres. E. SCHWARZ. 13 Nov., 1968 [17 Nov., 1967], No. 53914/68. Heading D1F. In apparatus for automatically and continuously testing a succession of fibre samples and determining the fibre length distribution in the fibre stock sampled, continuous relative movement occurs between a comb and a cooperating drum and in each cycle of such movement, in sequence, the comb removes fibres from tufts protruding through the drum shell, these fibres are secured to the comb to form a trading "beard", the fibres of the beard are parallelised by cards, the beard is optically scanned and light passing therethrough is converted into electrical signals which are evaluated and computed (so as, finally, to provide the required data) and the fibres are removed from the comb in preparation for the next cycle. As shown, a comb 17, carried around a drum 10 on a manually or power operated arm 13 swinging about axis 14, in an angular section 21 of its travel removes fibres from tufts 30 (of a bundle 11 within the drum) protruding through perforations 29; in section 22 an eccentrically mounted roller 18 is turned to clamp the fibres caught between the comb teeth; in section 23 the fibres are parallelised by cards 31 which also remove short fibres, neps and foreign matter; in section 24 the homogenuity of the beard may be improved, e.g. by reorientation of fibres as roller 18 is temporarily loosened; in section 25 additional cards 32 act on the beard; in section 26 the beard may be smoothed and further cleaned by a counter-revolving brush 33 and/or a vacuum suction device (not shown); in section 27 the fibres are scanned as by light from an elongated source 36 in an enclosure 37 passing through fibres (trailing over a transparent plate 38) and a slit 39 to impinge on a light sensitive element 40; finally in section 28 the clamping roller is released and the loosened fibres are pneumatically removed by blowing (or sucking) action of air flowing through a tube 34 and emerging radially through holes 35. According to modifications (not shown) the drum rotates and the comb and associated members are stationary, the drum may be oval or rectangular with semi-circular ends in crosssection, the comb may be guided by a rail equipped with control devices for actuating the several operations on the fibre (in sections 21-28), and the light source (36) may be stationary and/or external or the element 40 and the source 36 may be interchanged.
