Title: Magnetic memory members
Inventor: GASSAWAY JAMES SCOTT
IPC: G11B5/68
Filed: 1969-02-03
Abstract: 1,263,890. Magnetic structures. J. S. GASSAWAY. 3 Feb., 1969 [8 Feb., 1968], No. 4321/71. Divided out of 1,251,756. Heading H1H. In a magnetic memory member comprising a rigid substrate bearing a coating comprising magnetic particles embedded in a binder, the inner portion of the binder being bonded to the substrate, a major proportion of the magnetic particles are concentrated in the outer portion of the binder. The magnetic coating may be provided on each of opposed flat surfaces of the substrate, which may be a disc. The magnetic coating may be bonded to the substrate by a non-magnetic and electrically-insulating adhesive. The magnetic members may be made by a process of coating a flat master member with hardenable magnetic composition, bonding the substrate thereto, causing the magnetic particles to gravitate or be vibrated towards the master member, and then separating the magnetic coating from the master member (see Specification 1,251,756). Separation may be aided by a vapour-deposited metallic parting agent, which may remain on the magnetic coating as a protective film, or by adding a lubricant to the binder. In one embodiment, the memory member comprises an aluminium disc coated on both sides with a dispersion of magnetic iron oxide in epoxy resin.

The froth may contain a catalyst as long as it does not initiate polymerization at ambient temperatures. Conventional polyisoeyanates which may be masked are used. The active hydrogen-containing compound is suitably a polyether polyol or a polymer of a cyclic ester. Organosilicon surfaetants are preferred, especially trimethylsiloxy-silicate copolymers consisting of SiO 2  units and (CH 3 ) 3 SiO 0À5  units in a mol. ratio of 0À8 : 1 to 2À2 : 1, and partially cross-linked siloxane-polyoxyalkylene block copolymers wherein the siloxane blocks and polyoxyalkylene blocks are linked by silicon to carbon, or by silicon to oxygen to carbon linkages. Nickel catalysts, e.g. nickel acetylacetonate, may be used and conventional tin catalysts may be used in the presence of the trimethylsiloxy-silicate copolymer surfactants. Auxiliary blowing agents, e.g. high-boiling fluorocarbons, may be used. The inert gas which is preferably air, but may be nitrogen or carbon dioxide, is incorporated in the liquid phase by mechanical beating in amounts which must be adequate to provide a froth having a density of less than 45% of the density of the liquid phase prior to frothing. The froths can be shaped by moulds or doctor blades and cured by heating to temperatures above 70‹ C.

Title: Compositions for rendering textile materials resistant to creasing
IPC: C08F255/02
Filed: 1964-02-03
Abstract: Compositions for rendering cellulosic textile materials resistant to creasing comprise an aqueous dispersion of (1) an aminoplast resin, a polyfunctional formal resin, a polyfunctional epoxide resin or a bi- or tri-functional ethyleneimine compound, (2) an agent having an acid reaction and (3) a copolymer of ethylene and propylene and, optionally, a third monomer, on to which there has been graft polymerized a monomer containing a functional group, which group renders the grafted polymer cross-linkable. The grafting monomer is preferably one containing an -NH2 or -CONH2 group, e.g. acrylamide or b -aminoethyl acrylate; when acrylamide is used, the graft polymer obtained may be subsequently reacted with formaldehyde. Biscyclopentadiene may be used as the optional third monomer component of the base olefin copolymer.  Components (1) exemplified are dimethylol-ethylene-urea, dimethylol-dihyroxy - ethylene - urea, dimethylol - propylene-urea, di-methylol-urea di-methyl ether, hexamethylol-melamine trimethyl ether, dimethylolurea, tris - aziridinyl - (1) - phosphine oxide and glycol diglycidyl ether.  Acid agents (2) exemplified are magnesium chloride, ammonium chloride and zinc fluoborate.  In the examples, octadecyl-ethylene-urea plasticizer is additionally employed.  The compositions are cross-linked after application to a cellulosic textile material.ALSO:A process for improving the resistance of textile materials to creasing, in which said materials consist of (a) natural or regenerated cellulose fibres or (b) natural or regenerated cellulose fibres in admixture with a proportion of synthetic fibres that is insufficient to impart to the material resistance to creasing, comprises treating the textile material in a finishing bath with an aqueous dispersion of (1) an aminoplast resin, a polyfunctional formal resin, a polyfunctional epoxide resin or a bi- or tri-functional ethylene-imine compound and (2) an agent having an acid reaction (e.g. magnesium chloride, ammonium chloride or zinc fluoborate), and fixing the crease-proofing component (1) on the fibres by a thermosetting process, the improvement with regard to crease resistance being effected by simultaneously adding to the finishing bath an aqueous dispersion of (3) a copolymer of ethylene and propylene and, optionally, a third monomer (e.g. biscyclopentadiene), onto which there has been graft polymerised a monomer containing a functional group, which group renders the grafted polymer cross-linkable, (e.g. acrylamide or b -amino-ethyl acrylate).  The finishing bath may, if desired, also comprise a sizing agent or plasticiser, e.g. octadecyl-ethylene-urea.  Treatment of the textile with the finishing bath may be effected by dipping, spraying, painting or padding.  In Examples the treated materials are bleached and mercerised cotton poplin, printed staple fibre muslin fabric, and mercerised and dyed twill cotton fabric.
