  • Patent number: 4273810
    Abstract: Preventing work pieces of iron or iron alloys in the form of a line of blocks which are pushed through an induction coil and heated to a forging temperature from sticking together. The surfaces of blocks which touch are subjected to an elevated temperature of heating and pressure due to pushing causing sintering with sticking. The application of a finely-divided material of predominantly iron oxide to the surfaces prevents sticking together of the surfaces when subjected to elevated temperature and pressure.

  • Patent number: 4218294
    Abstract: Release coatings are provided by including in a liquid monomer or prepolymer polymerizable by electromagnetic or ionizing radiation a waxy material of limited compatibility therein. Upon application of a film of such material by casting, coating or printing, a thin layer of the waxy material migrates to the surface to provide, after cure, the desired release properties. The thin surface layer of waxy material also tends to exclude oxygen from the film to permit radiant curing in air. Preferably the polymerizable liquid comprises acrylate monomers with or without unsaturated prepolymers co-polymerizable therewith dissolved therein. Novel prepolymers especially useful for providing release films and other radiation curable coatings are described, including the reaction product of polyamides, containing primary and secondary amine groups with unsaturated polybasic carboxylic acids and particular reaction products of polyether triols with toluene diisocyanate, modified with unsaturated monomers.

  • Patent number: 4199620
    Abstract: This invention is a method for forming a protective, strippable, elastomeric film on a highly reflective surface. The method is especially well suited for protecting diamond-machined metallic mirrors, which are susceptible not only to abrasion and mechanical damage but also to contamination and corrosion by various fluids. In a typical use of the invention, a diamond-machined copper mirror surface is coated uniformly with a solution comprising a completely polymerized and completely cured thermoplastic urethane elastomer dissolved in tetrahydrofuran. The applied coating is evaporated to dryness, forming a tough, adherent, impermeable, and transparent film which encapsulates dust and other particulates on the surface. The film may be left in place for many months. When desired, the film may be stripped intact, removing the entrapped particulates and leaving no residue on the mirror surface.

  • Patent number: 4137344
    Abstract: A method of enamelling sheets (e.g. cooker panels) in which hooks are used to suspend the sheets during the enamelling procedure and in which deposits of enamel are prevented from building up on the hooks by covering them initially with an under-coat of non-pellicular aluminium paint. This has the effect of retaining the enamel that may be deposited on the hooks until after firing (thereby avoiding spoiling the enamel of the sheets with particles of broken hook enamel) but of enabling the enamel to be removed after firing either by heating and quenching the hooks or by vibrating them (or both).

  • Patent number: 4098925
    Abstract: To protect the underwater surfaces of a ship against fouling and corrosion, several layers of wax are applied, one layer on top of the next but each layer having a successively lower melting point and/or degree of hardness. After a certain length of time, when the outermost layer of the treated surface has become fouled or roughened in some way, it is thus possible to remove whichever layer is outermost by melting or brushing, since the treatment can be regulated such that the underlying layer(s) will not be affected.

  • Patent number: 3969157
    Abstract: An improved technique is described for effecting decarbonization protection for the surfaces of ferrous metals during heat treatment in an oxidation atmosphere. The surface to be protected is coated, prior to the heat treating step, with a paste-like substance preferably formed from a mixture of boron carbide, potassium boron fluoride, borax and an aqueous binder. The resulting protective coating, which may be sprayed on the relevant surface, has a maximum thickness of .1 mm. Such relatively thin coating having the described composition, which in larger thicknesses is useful for boron-hardening of metallic surfaces, is effective to provide the required decarbonization protection without the accompanying disadvantages of excessive boron atom diffusion.
