A laminated fabric suitable for use in the production of electric heating pads or blankets is produced by placing a product comprising a fabric laminated solely by adhesive to a sheet of foamed natural or synthetic rubber or plastics material in contact with another product comprising a fabric laminated solely by adhesive to a sheet of foamed natural or synthetic rubber or plastics material so that the foam surfaces are in contact with each other and then laminating the products together, the fabric and sheet being laminated together by applying an adhesive material or potentially adhesive material to one face of the fabric and/or sheet and placing the fabric and sheet in contact with each other with the treated surface(s) innermost and forming the adhesive band by heat and/or pressure. Where the laminated fabric is used for an electric heating pad or blanket lamination of one foam surface to another may be effected in spaced apart lines disposed so as to accommodate an electric heating element, the foamed material preferably being thermoplastic or treated with a thermoplastic material and welding being effected by the application of heat and pressure suitably by high frequency welding in which the material is heated by the passage of a high frequency electric current. Alternatively lamination of the foam surfaces may be effected by means of an adhesive, bonding being effected over the whole surface or over discrete areas thereof. The fabric may comprise cotton, wool, viscose rayon, polyamide, polyester or polyacrylonitrile fibres and is preferably a stitch bonded or needle punched non woven fibrous web. In the case of needle punched webs these may be laid on woven or knitted reinforcing fabric and subsequently needle-punched. The sheet of foamed material may be of acrylonitrile-butadiene or styrene-butadiene copolymer, polyvinyl chloride or foamed polyester or polyurethane foam formed using a blowing agent or by heating air into a latex followed by drying and having closed cells or interconnecting cells. The adhesive used for laminating the fabric and foam sheet together may be applied as a solution or dispersion by spraying, brushing or knife coating or in the case of a pulverulent or granular material by scattering. Suitable adhesives are styrene-butadiene or acrylonitrile-butadiene copolymer latex, hydroxypropyl methyl cellulose, polyvinylidene chloride latex, polyethylacrylate latex, polyethylene granules or nitrocellulose.

Abstract: 874,849. Regulating switches; actuation of switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 26, 1960 [May 22, 1959], No. 17560/59. Class 38 (5). In a cam-operable contactor or other switch, contacts 4c, 6 are normally kept open by means of a roller 3 resting on a cam surface 1d. Clockwise rotation of the operating shaft 2 and cam 1 allows a member 8 on contact arm 4 to strike a face 9a of a cam insert 9, which is preferably metallic. By this means the contacts 4c, 6 are spaced by a predetermined distance, e.g. 0.02 inch until continued rotation of the cam 1 allows the member 8 to drop suddenly off the cam insert surface 9a, when the contacts 4c, 6 are rapidly closed by the contact spring 7. The member 8 is pivoted to the contact arm 4 and upon reversal of the cam 1 the member 8 is tilted by the cam surfaces 9a and 1c to assist the resetting of the roller 3 upon the raised cam surface 1d. The predetermined spacing of contacts 4c and 6 may be adjusted, e.g. by means of shims on either or both contacts.

Title: Crust-bearing iron oxide agglomerate
Inventor: VEALE JOHN HEAGY
IPC: C22B1/24
Filed: 1957-06-04
Abstract: Agglomerates of iron oxide are strengthened by the formation of a surface layer of between 2 and 7 per cent by weight of the agglomerate consisting of calcium ferrite, magnesium ferrite or mixtures of the two.  The process is particularly applicable to iron oxide ores such as taconite or haematite agglomerated either to form bricks or nodules which are sprayed with, or dipped into, a slurry of calcium carbonate, magnesium carbonate or dolomite and after drying are heated to above 2300 DEG F to form the ferrite layer.  When free silica is present in the ore, lime is mixed with the pulverized ore which is nodulized by heating to 2400 DEG F in a sloping rotary kiln and the resulting nodules, which contain calcium silicate formed by a solid state reaction, are coated with a slurry of lime and water and heated to 2400 DEG F. to form the ferrite layer.  A small proportion of ferrite may be formed in the centre of the agglomerates by diffusion of the coating. Specification 818,615 is referred to.
