  • Patent number: 4686754
    Abstract: A method for manufacturing a heat insulating shaped bar including a pair of spaced side walls and a heat insulating connecting portion formed by heat insulating material and connecting the pair of side walls together from an integrally extruded metal shaped bar having the pair of side walls and a connecting wall (or walls) extending and connecting between the side walls is disclosed. The connecting wall(s) includes on one surface thereof a recess having sloped sides and extending longitudinally of the metal shaped bar and the method includes a step of cutting the material of the connecting wall(s) from the other surface at the area of the recess.

  • Patent number: 4620355
    Abstract: The invention provides a novel method for manufacturing a heat insulating sash bar comprising two face members connected together with two connecting members formed of a heat insulating material which is pourable and is cured or solidified after impregnating the space between the face members of a bar material of, for example, aluminum composed of two oppositely positioned face members connected together with at least one inner connecting part to have, for example, a H-wise cross section and provided with one or two pairs of inwardly extending flanges each on one of the face members.

  • Patent number: 4563322
    Abstract: A method and an apparatus for continuously filling grooves in metal sash bars with heat insulating synthetic resin are disclosed. The method comprises the steps of closing the opposite ends of the groove of each of the metal sash bars by end caps each having an end wall with a thinned top edge; continuously moving the metal sash bars through a path below an injection device with the grooves facing upwardly and with at least the top edges of the end caps of one preceding sash bar and the succeeding sash bar in close contact with each other on the upstream of the injection device; and continuously injecting a solution of the heat insulating synthetic resin from the injecting device into the grooves of the sash bars at a constant injecting rate while continuously moving the sash bars.

  • Patent number: 4342144
    Abstract: A method of manufacturing a thermally insulating sash bar from an elongated hollow metallic sash bar including a pair of spaced outer members connected by a pair of spaced first and second inner members so as to define between the outer members a pair of longitudinally extending first and second channels and a longitudinally extending hollow chamber. A mass of foamable and thermally insulating synthetic resin is introduced into the first channel and then cured to fill the latter with the cured or thermally insulating synthetic resin. Then, a longitudinal gap is formed in and along each of the first and second inner members. The longitudinal gap in the second inner member is covered with a thermally insulating strip. Finally, a mass of the foamable and thermally insulating synthetic resin is introduced into the second channel and then cured to fill the latter with the cured or foamed thermally insulating synthetic resin.

  • Patent number: 4210695
    Abstract: A colored pattern imitating the grain of wood is formed on the surface of an article formed of an aluminum or its alloy by dipping the article in a coating bath floating a coating material in a multilinear pattern or multiannular pattern to form on the surface of the article a masking film in a pattern of the wood grain, subjecting the article to an oxide film application or etching and, after removal of the masking film, subjecting the article to an electrolytic coloring process.

  • Patent number: 4210499
    Abstract: A colored pattern imitating the grain of wood is formed on the surface of an article formed of an aluminum or its alloys by dipping the article, after oxidation process, in a coating bath floating a coating material in a multilinear or multiannular pattern to deposit the coating material in a wood grain pattern on the surfaces of the article and applying thereto a finish coating.

  • Patent number: 4023244
    Abstract: An emergency opening slider to be mounted, in addition to the usual fastener slider, in any selected position on interlocked rows of fastener elements to permit the fastener to be forced open from the selected position in an emergency. The slider body has a guide channel therethrough which consists of contracted terminal portions at both ends and an expanded midportion, with the latter portion divided into a pair of branch channels where the rows of fastener elements are incapable of interlocking engagement. The slider body includes a portion or portions which, upon application of operating force as through a pull string connected thereto, are displaceable to permit disengagement of the fastener elements.
