  • Patent number: 4640070
    Abstract: Methods of adding floors to an existing building structure without altering the exterior of the structure is described. One method involves providing additional foundations within the existing structure and supporting a plurality of internal columns upon these new foundations. The internal support columns are brought through the existing roof and a large platform truss is supported on these columns. A conventional construction skeleton is built on the platform truss and provides as many floors as is required. Another method involves building a further foundation immediately adjacent the existing structure and supporting external columns and also providing new foundations within the existing structure with internal support columns. A platform truss is supported on the external columns and the internal columns and the platform truss acts as a base for conventional construction skeleton with as many floors as required above the existing building structure.

  • Patent number: 4640066
    Abstract: This invention relates to a vehicle window structure. The vehicle window structure includes a window glass, a body member, a window molding, a retainer for the window molding and a seal member between the window glass and body member. The window molding is in contact with the window glass and the body member. The window molding is fixed on the retainer which supports the seal member. Accordingly, the window molding, retainer and seal member are united to form a sealing assembly which is secured to the window glass before the window glass is fixed on the vehicle body. Further, the retainer has an engagement portion which can engage with the body member. Thus, the window glass and its sealing assembly can be attached to the body member in a simple one-step operation.

  • Patent number: 4630798
    Abstract: Proposed is a method for the erection of structures, such as bridges, that display pre-fabricated concrete beams, according to which the individual pre-fabricated beams are produced, on the spot, on a feed rigging within the corresponding work area of the structure, in a heated and laterally tiltable form. After removal from the form, the thusly produced pre-fabricated beams are transferred sidewardly into their final position by means of gantry cranes. During concretizing of the individual pre-fabricated beams, flexure of the feed rigging carrying the form is equalized in continuous fashion, in correspondence with the progressing, concretizing process, by transfer pumping of ballast liquid.

  • Patent number: 4628656
    Abstract: A demountable wall system is disclosed in which panels are removably connected to H-shaped metal studs. The principal structure of the panel is provided by a wallboard having a width less than the modular spacing between studs. Sheet metal mounting strips are adhesively secured along the opposite edges of the wallboard and are positioned with respect to each other so as to provide the assembled panel with an exact modular width. Each mounting clip includes a connector portion which releasably secures the panels to the studs and a finish portion which extends along but is spaced from the side edges of the wallboard. A facing sheet of flexible sheet material is laminated to the forward face of the wallboard and extends across the gap between the finish portion of the mounting clips and the wallboard to hide such gap. The facing sheet then extends back along the finish portion and is provided with an edge positioned where it is not likely to be loosened during the handling and assembly of the panels.

  • Patent number: 4627201
    Abstract: A window stay for the support of a window glass for use in vehicles, with a window frame and a glass retainer firmly secured to the window frame with the peripheral edge portion of the window glass sandwiched fluid-tight between the window frame and the glass retainer. An elastic cushioning strip encircles the peripheral edge portion of the window glass and is held in position between the window frame and the glass retainer during assembly of the peripheral edge portion of the window glass in the sandwich. To avoid relative displacement of the glass retainer, a rim projection is integrally formed with the window frame, thereby permitting the glass retainer to resist the reactive force exerted by the compressed elastic cushioning strip.

  • Patent number: 4625470
    Abstract: In order to provide a pleasing aesthetic appearance, and also in order to enable concealed, directional lighting to be used, an openword grid-like suspended ceiling system has outer squares which contain four inner blades forming an inner square surrounded by four rectangles. Light fittings are associated with the rectangles so that the axis of a light fitting can be inclined. In order to enable the ceiling system to be packaged at low packing density, the four inner blades are hinged to each other and collapse so as to lie parallel to each other. After opening out, they can be hooked into the sides of the outer squares.

  • Patent number: 4625475
    Abstract: An extensible mast is shown which is erected from a portable base having a plurality of tape reels mounted thereon. The tape reels are angularly oriented on the base with respect to a common, vertical axis, and each of the tape reels is adapted to receive a resilient metal tape having longitudinal edges for winding and unwinding the tape. A plurality of guide rollers on the base receive the respective longitudinal edges of the metal tapes and orient the tapes whereby the tapes are fed upwardly in planes parallel to the vertical axis and at an angle to each other to form a rigid structure. A geared winding mechanism, including a plurality of rotatable windings rotates about the vertical axis and wraps a wrap material about the rigid structure to reinforce the structure as it is being erected.
