Abstract: An endless loop article of manufacture comprises a core consisting essentially of at least one skein and a protective covering consisting essentially of hose fabric loosely enclosing said core, and a warp threading and a weft threading which latter comprises at least one monofilament thread extending transverse to the central loop axis, and preferably a monofilament and a multifilament thread arranged to run side by side. The protective covering comprises an endless toroidal part and an internal annular selvedge flange extending radially inwardly from the latter.A strap can be formed from such article of manufacture so deformed that opposite segments of the internal selvedge flange are brought into contact and sewn together, e.g. with an auxiliary warp thread, or by superimposing a protective layer to which the segments are sewn.The protective covering of the article can further comprise an external circumferential selvedge flange projecting radially outwardly from the toroidal part.

Abstract: A member adjacent to an engine, as an engine cover such as an engine head cover and oil pan and an air cleaner, is made of fiber layers by shaping organic or inorganic fibers mixed with a resin and its crosslinking agent while heating so as to cause a crosslinking reaction, thereby absorbing vibrations transmitted from an engine and remarkably decreasing noises resulting from surface vibrations of the member with the aid of the damping capacity of the fiber layers.

Abstract: A vacuum heat insulator comprises compressed glass fibers, a planar thin metal plate and a drawn metal plate. A receptacle is air-tightly formed of the planar thin plate and the drawn metal plate. The glass fibers are encased in the receptacle under a vacuum condition. A small amount of the glass fibers is penetrated thereinto in a direction perpendicular to the heat transfer direction of the insulator by inserting needles having hook portions into the glass fibers whereby the compressed glass fibers are kept under a vacuum condition at a high density without any remarkable deformation.

Abstract: In a building element of the type in which an internal core member of a material of an open air-permeable structure is covered on both side faces with cover boards and on the edge faces with edge strips, an adhesive bond having improved strength characteristics is obtained between the core member and the cover boards by means of a moisture-curing adhesive applied to the major surfaces of the core member and the internal surfaces of the cover board after application of moisture to all of said surfaces prior to arrangement of said core plate in an open casing formed by one of said cover boards and said edge strips, closing said casing by securing the remaining cover board to the edge strips and establishing a contact pressure between said surfaces by applying suction to the interior of the closed casing.

Abstract: A vacuum thermal insulation panel comprises a pair of laminated plastic and aluminum sheets together with a plastic edge strip sealed to the edges of the sheets so as to define an evacuable volume in which a glass fiber mat is disposed. The insulation panel of the present invention takes advantage of the light-weight, low cost and low thermal conductivity of plastic materials to form an evacuable volume into which a glass fiber insulating mat is disposed for support of the panel which is evacuated to provide improved thermal insulation. Additionally, a gas permeation barrier is employed on the edge strip of the panel to minimize gas permeation at its edges. A metal foil layer provides gas permeation protection through the large surface areas of the sheets themselves.

Abstract: Two sheets of reflective plastic film included in the construction of a fiber-insulated thermal garment mitigate radiated heat loss while retaining the conventional insulating properties of fibers. A layer of porous matted fibers separates the two layers of reflective sheets, holding them apart and allowing a free passage of air between. The plastic sheets are provided with venting holes which allow the garment to "breathe" and prevent moisture accumulation. The venting holes in opposing plastic sheets do not align but rather are offset, forcing warm air passing through the garment to follow a zigzag route. The plastic sheets are further provided with a flat black finish on their outer-facing surfaces in order that the inside sheet may recapture radiated heat from escaping warm air and the outside sheet may absorb any ambient radiated heat, such as sunlight.

Abstract: A thermal drapery construction including first and second metalized fabric panels, a third panel of high loft, low density, randomly oriented fibers disposed between the first and second panels and a thermal drapery liner located adjacent the metalized surface of the second fabric panel. The panels and liner are typically bound together along their aligned outer edges to form a highly insulating liner assembly. The liner assembly is lightweight, flexible, drapes well and can be used in conjunction with a decorative drapery fabric opposite the metalized surface of the first fabric panel to form pleated hung draperies. Adhesive means, such as magnetic strips, can be attached to the outer surface of the liner to seal against heat loss between the liner assembly and the window.

Abstract: In the manufacture of a building element of the type in which an internal core member of a material of an open air-permeable structure is to be covered on both side faces with cover boards and on the edge faces with edge strips by gluing with a moisture-curing adhesive, contact pressure is established by applying suction directly through an opening in one of the edge strips to produce an underpressure in the core member. Thereby, and by applying the amount of moisture necessary to cure the adhesive to the cover boards prior to application of the adhesive, a considerable reduction of the processing time and, thereby, a simplification and cost reduction is obtained. Relative to usual mechanical pressure application technology, adhesive bonds having improved strength characteristics are obtained together with effective removal of poisonous fumes arising during the curing.

Abstract: A three component adhesive is used for a nonwoven web in combination with a water based lotion containing borate ions. The adhesively bonded web has substantial tensile strength while saturated with the lotion for extended periods of time (e.g., months) and is water dispersible when exposed to a large volume of water. The three component adhesive system provides the tensile strength for the web during prolonged exposure to the water based lotion even under extreme temperature conditions. The components of the adhesive composition applied to the web are polyvinyl alcohol, a non-self-cross-linking, thermosetting, polymer emulsion and a self-cross-linking thermosetting polymer emulsion. An organic acid capable of complexing with borate, such as .alpha.-hydroxy acids or o-aromatic hydroxy acids, when in combination with borate ions in the lotion produces a synergistic effect upon the PVA adhesive in the web.
