Abstract: A multi-paned insulated light, such as a window, incorporates an interior panel spacer/seal that includes a thermal insulating layer of cardboard. The cardboard serves as a low cost insulating layer and may be used in conjunction with rolled or extruded metal spacer forms, so as to vastly diminish the thermal bridging effect normally present with such metallic sections. The cardboard spacer can be used adjoining either the "cold" pane or the "hot" pane of the multi-paned unit, or may be interposed between adjacent metallic sections, as a thermal break therebetween. The cardboard is preferably sealed with a surface sealing layer such as polyvinyl alcohol, to effectively preclude gas percolation therepast. Alternatively, an effective gas seal such as polyvinyl alcohol may be incorporated into the cardboard at its time of manufacture.

Abstract: A spacer/seal for use in multi-pane glazing units, to provide a thermally non-conductive peripheral hermetic seal comprises a hollow tube of selected cross-sectional form, built up of a laminated construction of helically wound laminated layers and incorporating a layer or layers of gas impermeable barrier material to ensure long lived hermetic sealing characteristics. The construction may include respective layers wound to opposite hand, and layers wound to different lead angles. Also, the gas impermeable barrier layer or layers may be selected from materials that serve as adhesive to the laminated structure. Suitable barrier layers may be selected from polyvinyl alcohol, polyvinylidene chloride, thermoplastic polyesters, ethylene vinyl alcohol copolymers, and combinations thereof.

Abstract: A window spacer system for multi-paned window and door lights uses a paper or carboard substrate, generally built up in laminated ribbon structure as a low cost hermetic seal possessing unusual thermal insulating and thermal expansion characteristics. The ribbon may be impregnated or laminated with superior sealants, including polyvinyl alcohol and SARAN (TM) and can be scored or marked for folding into hollow seal sections, from which a peripheral seal frame can be readily manufactured. Metallic foil, in a range of thickness can be incorporated, to enhance the sealing characteristics, and in certain instances to provide a dead-fold characteristic to the seal ribbon.

Abstract: An insulative, gas impermeable spacer frame is provided for the precision separation of two or more transparent glass or plastic panes, and is hermetically sealed in place to prevent the ingress or egress of moisture vapor, and to contain various noble gases, or air, between the adjacent panes, being used in insulated lights for windows and doors. The spacer is made of insulative organic material of suitable stiffness such as cardboard, or plastic over which is applied a coating or lamination of gas and moisture vapor barrier materials, thus forming a composite insulative web which may be fabricated into tubular structures to form separate frame units. Such spacer structures may possess extremely low thermal conductivity, so as not to constitute a thermal bridge between the panes being separated, thereby diminishing and even eliminating the problem of window edge frosting and/or peripheral dew point development, such as occurs when metal spacer devices are used.

Abstract: A system for providing multi-paned glazing lights, primarily for use as insulated glazing units in door and windows, employs noble gases for filling the insulative spaced enclosed between the glazing panes. The system uses the glazing light or lights as a gas flow manifold, mounted within a sealed vacuum chamber, for evacuating the chamber and the one or more glazing lights located therein. The glazing light, or lights, then also serve as the gas flow manifold for filling the lights and the surrounding exhausted chamber with the required noble gas. The system operates at room temperature, and enables selection of the internal pressure of the noble gas within the glazing units, in accordance with predetermined factors such as the altitude of the ultimate site where the lights are destined to be used. The lights are sealed off within the vacuum chamber, prior to removal therefrom, while in a controlled environment.

Abstract: A peripheral frame is provided suitable for use as the frame or sash for a glazed window or patio door unit, or for use as an outer frame or semi-peripheral frame to contain window or door units. The frame is of U-form section, having a pair of substantially parallel legs and an interconnecting end portion forming an outwardly facing bight. The outer surface of the section end portion forms the inner periphery of the frame and the leg portions of the section form the faces of the frame, and, provide an outer peripheral access to the interior of the frame section. The frame can be provided with various concealed inserts appropriate to its function located in the interior of the section, such as wood, metal or other inserts. Such inserts may comprise reinforcement frames and insulation material, including foamed in-situ insulation and reinforcement; and attachment and/or suspension hardware for components supported by the frame.

Abstract: The invention teaches an improved arrow construction which, by the partial or complete elimination of tail feathers as a means for stabilizing flight trajectory, improves both the speed and the accuracy of the arrow. A resilient stabilizing tail is substituted for tail feathers which substantially eliminates aerodynamic drag. In addition, the invention contemplates the use of a "shock piston" within the interior of the arrow shaft which serves to increase arrow penetration in the target by striking the arrow head after the initial target impact.

Abstract: A method of and apparatus for injection molding solid steel-banded industrial rubber tires wherein a steel band is inserted in the bottom mold member cavity when the top mold member is in open position. Bite ring and knockout member components are contained in mold member cavity recesses. Closing movement of the mold members to mated position seals the bite ring and knockout member components against the steel bank and mold member recess surfaces to prevent leakage of injected rubber compound from the cavity during injection and curing. The mold has an internal wedge member which expands a split ring against the steel band when the mold is closed to prevent band distortion from pressure existing when the mold is injected and the rubber is cured therein to form the tire tread portion which is bonded to the steel band during curing. Mold components knock the cured tire out of the top mold member upon opening the mold.

Abstract: Interlocked channel section panels having an interlocking joint wherein the male and female members are provided with deformable hook portions. During field assembly the female member overlies the male member with the outer surface of the corresponding upstanding members and upper portions of the male and female members adapted to mate throughout their lengths, and the deformable flange hook portions of the male and female members are capable of being reformed so as to conform intimately to effect continuous, positive interlocking of male and female ribs. A clip connector, including a body portion tightly sandwiched between associated corresponding upstanding members, upper portions and deformable flange hook portions of the sidewalls of the coupled panels, and a foot at the other end of the body portion of the clip connector anchored to a supporting member and fastening the connector along with the coupled panels to the supporting member, is also provided.

Abstract: A rolling support for moving scaffolding alongside the side or end of a building under construction, the support including frame structure which rigidly connects two outriggers together, a leading outrigger and a trailing outrigger, each of such outriggers having a near-side traveling wheel to ride on an exposed structural roof member adjacent the side or end of a building, and a far side force roller which extends beneath a parallel exposed structural roof member inwardly from the side or end of the building, the outriggers being parallel to one another and riding on parallel exposed structural roof members. The near-side travel wheel bears down on its exposed roof member and exerts substantial downward pressure thereon while the far-side force roller bears upwardly against the underside of its exposed roof member. Remote controlled motor means are mounted on the frame so as to drive the near-side traveling wheel.
