Title: Fibrous Sheet Compositions
IPC: C08J9/42
Filed: 1967-07-05
Abstract: 1,183,616. Fibrous sheet materials. GENSET CORP. 5 July, 1967 [5 July, 1966], No. 30942/67. Heading B2E. A fibrous sheet material comprises fibres distributed throughout a polyurethane foam with a dispersed, resilient soft filler not completely filling the pores of the composition, the fibres having sufficient movement so that individual fibres adjust themselves to disperse applied stresses over several fibres. The polyurethane may be formed from a polyester or a polyether. Suitable polyethers and polyesters are listed, as well as suitable polyisocyanates. The foams may have opencell or closed-cell structure. The polyurethane foam may also have dispersed therein a thermoplastic vinylidene chloride polymer containing at least 25% by weight of chlorine. The fibres may be of natural or synthetic materials such as polyesters, acrylics, polyamides, modacrylics, vinyls, cellulosics, wool, or silk. The fibres may be crimped or uncrimped and may have a denier between 0.5 and 6. The filling material may be a soft-resilient thermoplastic or thermosetting material such as polyurethanes and copolymers of butadiene and acrylonitrile and may contain surfactants, lubricants, or blowing agents. At least one surface of the material may be coated with a flexible polymer which coating may be porous and comprise a poly urethane, a polyacrylate, a vinyl polymer, a polyester, an epoxy or a polyamide. The products of the invention may be prepared by placing a fibrous mat on the flexible foamed sheet, forcing the fibres of the mat into the sheet to produce an integrated fibre-foam combination, compressing the fibre-foam at a temperature and pressure sufficient to cause the combination to retain its compressed dimensions, impregnating the compressed product with a filler material, depositing the filler material into the substrate either by heating or by coagulation by the addition of a miscible liquid in which the filler is not appreciably soluble, and again compressing to produce a substantially permanently set product of the desired dimensions.

Convention date, Nov. 20, 1929. [Class 55 (i).] In the manufacture of carburetted water gas in which the entire depth of the fuel bed is blasted and blue water gas generated by steaming the ignited fuel bed, the blue water gas is carburetted by oil introduced at the top of the fuel bed as well as by oil introduced to the carburetter. The fuel bed 5 is blasted with air admitted through inlet 6 and the blast gases burnt in the carburetter and superheater with secondary air supplied through inlet 16. An up-run is then made with steam from inlet 7 and simultaneously oil is sprayed on to the top of the fuel bed through the spray 12. The mixed gases pass through the carburetter and superheater to collection. During the latter part of the "run," oil is introduced into the carburetter through the spray 14, but both oil admissions may be simultaneous. The cycle may be completed by a down-run by steam supplied at inlet 21, the gases passing off through offtake 9. The oil introduced into the generator is such as to leave a high coke residue, and that introduced into the carburetter a low coke residue.

Abstract: 905,289. Polyfocal contact lenses. PLASTIC CONTACT LENS CO. Sept. 15, 1959 [Oct. 6, 1958], No. 31438/59. Class 97 (1). A poly-focal or mono-focal contact lens is adapted to adhere to the cornea by the lacrimal layer's capillary attraction and has means to prevent it from rotating on the cornea. An example of a bifocal lens is shown in Fig. 2, in which the radii of curvature of zone 30 are chosen for distant vision and those of zone 32 for near vision. The posterior radii of the zone may be equal in order to prevent the lens from rotating either its centre of gravity is arranged to be below its axis or its posterior surface is made toric to correspond with the shape of the eye. The centre of gravity may be lowered by (1) making the lower zone thicker than the upper zone, for example, by making zone surfaces eccentric, (2) by inserting in the lower zone a heavier piece of glass or plastic, in which case the change of power may be due to the different refractive indices of the zones and not to their different radii, or (3) by replacing the circular outlined lens by one having the outline shown in Fig. 8. One way of forming the lens (see Fig. 12) is to mould a large lens 56, the radii of which correspond with those required for one of the zones and then cut or mould a section 132 of this lens to the curvature required for the other zone. Several lens L<SP>4</SP> may then be cut from this large lens. Specification 882,907 is referred to.
