Filed: 1955-12-28
Abstract: 795,515. Snap-action linkages. AMERICAN SEATING CO. Dec. 28, 1955, No. 37070/55. Class 80 (3). A snap-action two-position control lever 20 actuating a slide-rod 18, particularly for locking an aircraft pilot's shoulder harness reel, is pivoted at 21 and acted upon by two compression springs 32, 38. Each spring surrounds a tube pivoted to the lever, and each tube telescopically houses a pin whose head 30 or 36 pivots in a socket in the casing 10. In the position shown the lever 20 is held only by the spring 32, since the line of action of spring 38 passes through the axis of the lever pivot 21. The lever may thus be readily " flicked " to its other position, the lines of action of the two springs changing so that the lever is firmly held in its other position by the combined action of both springs. The lever 20 and rod 18 are coupled by a roller on the lever engaging a recess in a slide-bar on the rod, forward and rear stops being provided for the slide-bar. It is stated that in a modification the two springs may lie on the same side of the lever. Specification 795,517, [Group XXXIV], is referred to.

Title: Non-woven fabric usable as a substratum sheet for artificial leather and process for producing the same
IPC: D04H3/10
Filed: 1975-09-10
Abstract: 1514553 Non-woven leather substitute ASAHI KASEI KOGYO KK 10 Sept 1975 [13 Sept 1974 8 Aug 1975] 37263/75 Heading D1R A non-woven fabric comprises filaments or fibres having a denier of 0.005 to 0.5 present both as individual filaments or fibres and as bundles thereof, the filaments or fibres within the bundles being autogeneously adhered together, the individual filaments or fibres and the bundles being entangled together yet free to move somewhat at their cross-over points. The fabric may be impregnated with polyurethane and coated with polyurethane to form an artificial leather. Viscose rayon or cuprammonium rayon filaments may be extruded, incompletely coagulated, formed into bundles of 50 to 1000 filaments and allowed to adhere to the other filaments of their bundle. In Examples 9 and 27 a blend of nylon 6 and polystyrene was extruded, solidified and the polystyrene dissolved in hot trichloroethylene or chloraform to leave the nylon 6 "island" filaments which were then caused to adhere to each other by exposure to steam at 130 to 200C. Filaments of cellulose diacetate, cellulose triacetate, nylon 66, polyethylene, polypropylene and polyacrylonitrile are mentioned. The filament bundles and/or the fabric formed therefrom may be sized with polyvinyl alcohol, methylmethoxy nylon 6 and/or a nylon 6-nylon 66-nylon 612 copolymer. The size may be removed before or after impregnation of the fabric with a dimethylformamide solution of polyurethane and immersion in water to coagulate the polyurethane. The filament bundles may be crimped in a stuffer box. The filament bundles may be random laid (examples 3, 7, 9, 10, 11, 14, 15, 16, 19) or parallel laid (examples 12, 13, 22) on a wire mesh belt and the resulting fabric may be cross laid. In examples 24-27 a filament bundle is cross wound, e.g. upon a frame of diameter 1m using a traverse guide at a cross angle of 85. The layer is then cut along the longitudinal axis of the frame. In examples 17 and 17 the fabric is formed from an aqueous slurry, of cut bundles by a paper-making process. In examples 18, 20 and 21 cut bundles are air laid. In examples 1, 2, 4, 5, 6, and 8 they are carded and cross-lapped. The fabrics may be needled or subject to water jets or to both in either order in order to break some of the bonds between fibres in a bundle and to cause entanglement. In example 3, the fabric is calendered by a pair of rollers at 170C before impregnation with polyurethane solution. The amount of individual filaments or fibres and of bundles of 5 or less filaments or fibres is preferably 5 to 95% by wt. of the fibres/filaments. The flexural rigidity in mg/100 denier of the fibrous bundle is determined by a press bending test to be between 0.15 and 5 times the Youngs Modulus (in g/denier) of a filament, Youngs Modulus for a cuprammonium filament being about 100g/denier. The weight, thickness, tensile strength, breaking elongation and ratio of weight of polyurethane to weight of fibres is specified for each example.

Title: Improvements in or relating to melt spinning process and apparatus
IPC: D01D5/08
Filed: 1956-12-07
Abstract: Filaments are produced by extruding molten filament-forming material through a spinneret in the form of at least one filament in semi-liquid state, removing excess heat from the extruded semi-liquid filament near to the spinneret, reheating it immediately thereafter along a portion of its length so as to reduce its cross-sectional area, and collecting the reduced filament in the solidified state at such a rate as to impart not more than 5 grams tensile stress to the filament and preferably to avoid stretching or tensile stress on the filament as far as possible.  As shown, suitable apparatus comprises a hopper 4 which feeds filament-forming material, e.g. cellulose acetate, to a screw conveyer having a first screw section 12 of large diameter, substantially completely surrounded by a cooling jacket 14, and a smooth frustoconical section 26 connecting the first screw section to a second screw section 30, the latter being disposed in a heating chamber 20.  Filament-forming <PICT:0816016/IV (a)/1> <PICT:0816016/IV (a)/2> <PICT:0816016/IV (a)/3> material in powder form is fused and conveyed by second screw section 30 to spinneret 34 from which it emerges as a semi-liquid filament 40, which is cooled in housing 42, e.g. by application of a vacuum, reheated to a temperature above its melting-point in jacket 46 by heating bands 48, to reduce its denier, and collected on winding device 54 adjusted so that the filament tension indicator never exceeds 5 grams.  The single-apertured spinneret 34 may be replaced by spinneret 60 (Figs. 4 and 5) having a concave upper surface 62 and a plurality of tapered apertures 64 which converge on the inlet side so as to give an even overall pressure distribution on the spinneret plate.  Soluble and insoluble dyes and pigments may be incorporated in the filament-forming material.  Other specified filament-forming materials are cellulose propionate, cellulose acetate/propionate, cellulose acetate/formate and cellulose acetate/butyrate. Specification 777,475 is referred to.

In the manufacture of optical fibres 15, comprising a glass core and a sheath of a different glass, by drawing the fibre through coaxial orifices 7a, 8a in the bottoms of two crucibles 7, 8 placed one within the other, the outer crucible 8 contains the sheath glass 10 and a rod 1 made of the core glass is introduced into the inner crucible 7 and the drawing speed, the temperature of the glass 10 and the length of the rod 1 extending into the inner crucible 7 are regulated so as to maintain only a low level of core glass in the bottom of the inner crucible. This reduces the time at which the core glass is kept at drawing temperature and prevents discoloration and devitrification. The crucible 8 is surrounded by electric heating means 9 and the rod 1 is heated by the molten glass 10. The rod 1 is secured to a bracket 2 movable vertically by a screwthreaded rod 3 rotated from shaft 4 by gear-wheels 5 and 6, the rate of lowering being adjusted according to the speed of the drawing rolls 14 and the temperatures used. The crucible 7 is mounted on an arm 11 fixed to a bracket 13 by an adjusting screw 12 so that the relative positions of the orifices 7a, 8a can be adjusted to control the thickness of the sheath. To avoid bubbles in the glass in the inner crucible, a platinum filament may be secured to the crucible so as to lie between the rod 1 and the level of the glass to guide the thread of glass from the rod. The orifice 7a may be tapered to extend into a tapered orifice 8a. The glass core may have the following composition in percentages by weight: SiO 2  14; B 2 O 3 17; BaO 48.5; La 2 O 3  10.5; ThO 2  10.
