Title: Improvements relating to regenerated cellulose fibres, threads, films and the like
Inventor: REEDER FRANK
IPC: D06M13/11
Filed: 1956-08-02
Abstract: Regenerated cellulose threads, films and like products having a reduced water imbibition are produced by applying to the products a compound containing at least two 2 : 3-epoxypropyl groups and then heating to bring about reaction between the regenerated cellulose and the epoxy compound.  The regenerated cellulose products may be treated with an aqueous solution of the 2 : 3-epoxypropyl compound, e.g. bis-(2 : 3-epoxypropyl)ethyl amine or tris-(2 : 3-epoxypropyl)amine, dried and then heated at 70-150 DEG  C. for 5 minutes to 12 hours.  Alternatively the impregnated products may be heated in a closed vessel to effect the epoxide-cellulose reaction and then washed and dried.  The process may be modified by using a compound containing two or more 3-chloro-2-hydroxypropyl groups, e.g. tris-(3-chloro-2-hydroxypropyl)amine, the heat treatment being then effected in the presence of alkali to convert the 3-chloro-2-hydroxypropyl groups into 2 : 3-epoxypropyl groups on the products.  Compounds containing one or more 2 : 3-epoxypropyl groups as well as 3-chloro-2-hydroxypropyl groups, e.g. N,N1-bis(2 : 3-epoxypropyl)-tetra-(3-chloro-2-hydroxypropyl)ethylene diammonium chloride, may also be used.  In one example, staple fibres of "never-dried" viscose rayon are treated. Specifications 471,880, [Group IV], and 795,356 are referred to.

Abstract: 1450791 Laminates VICKERS Ltd 6 Aug 1974 [18 May 1973] 23929/73 Headings B5N and B5A [Also in Division C3] A sound absorbing material comprises contiguous first and second layers, the first layer being a sound absorption layer formed of a composition comprising an elastomeric material and a particulate filler material and provided on a surface with a plurality of integral tapered projections and the second layer being a layer of syntactic foam having a surface in contact with the said surface of the first layer. The second layer is of a cured resin matrix, e.g. of epoxy, phenolic or polyester resin, containing hollow lightweight particulate filler material, e.g. hollow microspheres derived from pulverized fuel ash produced by the firing of pulverized coal. The first layer may be of butyl rubber or polyurethane rubber containing, as filler, lead, aluminium or graphite particles or crushed mineral rock, the filler material being homogeneously distributed throughout the elastomeric material or distributed in a manner such that the concentration of the filler is graduated so that it is a maximum at the tips or bases of the projections. The projections may be in the form of rectangular pyramids, triangular pyramids, right circular cones, single sided wedges or double sided wedges, the tips of the projections bein pointed or rounded. The sound absorbing material may be produced by applying the curable resin containing hollow lightweight particulate filler material on to the surface of the sound absorption layer provided with projections and curing the resin, or by providing a cured syntactic form layer having a surface including recesses of a configuration and size corresponding to the configuration and size of the desired projections, and applying the elastomeric material containing filler on to the surface thereof to fill the recesses and form a continuous layer. In use, e.g. on an underwater structure, the sound absorbing material is suitably positioned so that the tips of the projections point towards the sound source. When the underwater structure is a metal vessel the free surface of the first layer of the sound absorbing material is bonded to the outer surface of the vessel, and when the underwater structure is a hollow vessel having walls of glass fibre-reinforced plastics material the free surface of the second layer of the sound absorbing material is bonded to the inside surface of the vessel.

Abstract: 302,210. Bell, W. T., and Bennett, J. F. Sept. 12, 1927. Surface markings. - A machine for marking roads, tennis courts, and the like, has a roller or wheel 1 provided with V, U, or other shaped projections or ridges 2 or a series of pyramidal or rounded projections for impressing recesses in the ground, and a hopper 4 for feeding marking composition through a pipe 5 into the recesses. The invention is shown applied to a road roller, the rear roller 3 of which is fitted with a special ridged roller 1 for grooving the ground. The roller 1 is mounted on the axle 11 of the roller 3 by means of an eccentric bush 10 which can be adjusted to raise or lower the roller 1 by a worm gear 14. The pressure on the roller 1 may be increased by weighting material placed in a container 15. In a modification, the rigid roller is fixed to the end of the main roller. The marking material, which may be extruded from the hopper 4 by a worm driven by the chain gear 9, is plastic when kept airtight but hardens quickly on exposure to air. Heat may be applied to the roller 1 and to the hopper 4. A plain roller may follow the grooved roller 1 and a rotary brush or scraper may clean the road in front of the marking means.

Abstract: 1 : 8-Dicyano-2 : 6-octadiene or a mixture of 1 : 8-dicyano-2 : 6-octadiene and 2-vinyl-1 : 6: dicyano-4-hexene is obtained by heating a solution of 1-chloro-4-cyano-2-butene in an inert solvent (e.g. an aliphatic alcohol or nitrile) in the presence of iron powder.  The presence of the 2-vinyl-1 : 6-dicyano-4-hexene product may be avoided by using an iron powder produced by reduction of an iron oxide or hydroxide or an iron powder to which has been added a nickel salt.  The 1 : 8-dicyano-2 : 6-octadiene and the 2-vinyl-1 : 6-dicyano-4-hexene may be hydrogenated to sebacic nitrile, and ethylsuberic nitrile respectively and the latter compounds may be hydrolysed (e.g. with concentrated hydrochloric acid) to give sebacic acid and ethylsuberic acid respectively.  The 1 : 8-dicyano-2 : 6-octadiene may alternatively be hydrogenated to give decamethylene diamine, or hydrolysed to give octa-2 : 6-diene-1 : 8-dicarboxylic acid, which is preferably converted to the alkali metal or ammonium salt prior to subsequent hydrogenation to the corresponding sebacic acid salt.
