  • Patent number: 4488882
    Abstract: To apply hard cutting particles, for example of tungsten carbide, on the surface of the cutting edge of a cutting tool, such as a saw blade, a drill, or the like, the cutting edge is partially melted by an energy beam, for example a laser beam, or an electron beam. A laser beam is preferred since, then, the process can be carried out in air, or in a protective gas atmosphere, rather than in a vacuum. The beam partially melts the cutting edge and the granules of the hard metal particles, preferably in a random grain size of between 0.3 to 1.5 mm is permitted to run down, over the partially melted surface, excess being collected for reuse; alternatively, the partially melted surface can be dipped into the granules, and permitted to solidify.

  • Patent number: 4489030
    Abstract: A method of making a top toothed endless power transmission belt construction that is formed mainly of polymeric material and a belt construction made by such method are provided, the method comprising the steps of disposing the material in substantially cylindrical form on a substantially cylindrical drum-like support member, disposing a substantially cylindrical toothed member about the disposed material, compressing one of the members toward the other of the members with the pressure of pressurized steam to form top teeth in the material and cure the thus formed material with the heat of the steam into a top toothed belt construction, introducing pressurized steam against the other member during part of the time that the one member is being compressed toward the other member by the pressure of the pressurized steam, and temporarily releasing the pressure on the one member before the polymeric material has been cured to permit the gas that has been initially heated and thereby expanded in the polymeric mate

  • Patent number: 4486376
    Abstract: A modified polymeric membrane having an excellent separating property is produced by applying, to a porous polymeric membrane, a volatile treating liquid containing a modifying agent which consists of at least one member selected from:(A) volatile dissolving organic liquids each capable of dissolving therein at least 1% by weight of the porous polymeric membrane at a temperature of 25.degree. C.; and(B) volatile shrinking organic liquids each capable of causing the porous polymeric membrane to shrink at a shrinkage of 3% or more.

  • Patent number: 4478781
    Abstract: Polycarbonate water bottles are refurbished by automated cycling through conveyor system having a loading and unloading section, a temperature adjusting section, a vapor exposure section, and a cooling and curing section. Each of the sections are associated in a continuous circuit by means of a conveyor system which conveys a plurality of bottles through the refurbishing system. Each bottle is first heated to not less than 103.degree. F. and then cooled to a predetermined state wherein the thinner portions of each bottle are at a temperature in the range of 75.degree.-80.degree. F. and the thicker portions are at a temperature in the range of 90.degree.-95.degree. F. Each bottle is then subjected to a dichloromethane vapor cloud for at least 10 seconds, during which time the skin layer becomes fluidic and the surface tension causes all blemishes and scratches to be removed.

  • Patent number: 4478609
    Abstract: A machine for surface finishing wood veneer feeds the veneer to a grinding drum positioned over a rigid bed plate. A continuous loop feed belt carries the veneer to and away from the bed plate but passes thereunder to permit a rigid gap between the bed plate and the drum grinding surface. The drum is carried on a swing arm that is independently driven about an arc between a working position and a retracted, repair position.

  • Patent number: 4474722
    Abstract: A method of making hard surface prototypes or styling concept models by assembling a contoured polystyrene foam pattern and applying an epoxy clay-like material in two steps to replace the surface of the polystyrene foam pattern. The polystyrene foam pattern is first assembled from blocks cut out to design drawing specifications. The pattern is then shaped to the design contour. The surface of the pattern is then grooved and the grooves filled with the epoxy clay. The remainder of the pattern surface is then removed and replaced by more epoxy clay which is then sanded and finished with paint and suitable trim pieces.

  • Patent number: 4474723
    Abstract: A plastic pipe part 1 is pushed across a head part 3 of a sealing sleeve 4, being supported by a support 8, thereby providing the plastic pipe part with a widened end 7. Subsequently the widened end is surrounded by an outer mold 11 with three successive widenings 12, 14, 15 and by means of a fluid pressure in the interior of the widened end 7, sealed by the head part 3, the widened end is provided with three socket end widenings 28, 22, 29. After removal of the support 8 the end portion 6 of the socket end is inwardly rebent around the head part 3 thus forming a groove chamber 5 retaining the head part 3 of sealing sleeve 4. Pushing the plastic pipe part across the head part is facilitated by applying a fluid pressure.

  • Patent number: 4472334
    Abstract: A method of making a magnetic core for a coil so that the coil obtains a desired final inductance value. The core is introduced into the coil by partly filling the inner volume of a coil former with a soft magnetic powdery material which is subsequently maintained in the correct position by the deposition of a tough liquid material on the powdery material surface, said tough liquid material forming a cover plate after curing.
