Abstract: A method of joining composite parts including disposing reinforcing elements through the thickness of two composite adherends to be joined, at least a number of the reinforcing elements extending from the joint surface of each adherend; assembling the adherends so the joint surface of one faces the joint surface of the other defining a joint region therebetween, wherein the extending reinforcing elements are interstitially disposed in the joint region; and disposing an adherent within the joint region about the interstitially disposed reinforcing elements and the joint surface for providing an improved and reinforced joint.

Abstract: A veneer for the veneering of especially curved surfaces has a face veneer formed from thin veneer sheets. The veneer sheets are adhesively bonded along their edges so as to be butted flush and on the side opposite the visible side to a mock veneer which is arranged underneath and which extends over the entire region of the face veneer. To maintain the relative movability between the veneer sheets and the mock veneer, an adhesive is coated on underneath the veneer sheets and is influenced in its setting reaction. In terms of the setting reaction, the adhesive is still reactive over a particular timespan. Thus, when the veneer is finally applied, the adhesive does not tear apart at the joints during a shaping curvature of the veneer because the adhesive in the joint region of adjacent edges of the veneer sheets is set completely.

Abstract: A space filling unit for use in a container for cargo shipment to prohibit shifting of the cargo is formed by flat first and second panels, with first and second slots formed in each so that, when assembled, an x-shaped structure is formed. When placed in the container, respective end edges of the panels are supported on the bed of the cargo container while the other of the panel's end edges engage the container's sidewalls. The panel side edges form a pair of x-shaped bases which serve to support the cargo against movement toward the end wall of the container. An anti-slip element may be included on the respective end edges, braces may engage the panels proximate respective end edges, and panel wear on the cargo. An auxiliary bearing penal may also be used adjacent at least one of the x-shaped bases. A plurality of x-shaped structures may be utilized in the present invention, with a corresponding plurality of bearing panels interposed between the x-shaped structures.

Abstract: A cylindrical filter is formed from a sheet of filter material which includes two connected layers of filter media. Opposed edges of the sheet are joined to form the cylinder by separating the media adjacent the edges and then sealing together the first of the separated layers followed by sealing the second of the separated layers. The two seals are spaced inwardly of the edges and are spaced from one another. In this way, failure of one seal does not result in failure of the cylindrical filter.

Abstract: A portable display device for displaying educational material or student's work comprising a plurality of panels, each panel separated from the next adjacent panel by a score line to permit relative movement between adjacent panels, each panel comprising a base portion including a first and second corrugated substantially rigid section separated by a substantially rigid member and a writing surface adhered to the outer surface of the first corrugated substantially rigid section, the score line formed between adjacent panels extending entirely through the second corrugated substantially rigid section and a portion of the first corrugated substantially rigid section such that adjacent panels may be folded relative to each other for storage and transport or extended relative to each other for display.

Abstract: A woven conveyor belt splicing fabric of optimal strength, elongational and dimensional properties is produced by intermeshing relatively high tenacity and relatively high elastic modulus warp yarns (e.g., KEVLAR yarns) in a highly crimped one-by-one weave construction with nylon or other suitable filling yarns. The tenacity of the warp yarns provides high strength per unit fabric thickness while the crimp of the warp yarns provides a limited degree of initial stretchability of the fabric from a relaxed state sufficient to accommodate strain and deflective forces imposed on a conveyor belt splice during normal belt operation.

Abstract: Spun textile yarns from new polyester staple fiber, and downstream textile articles, such as fabrics and garments, made from such, and blends thereof, wherein the staple fiber is of intentionally mixed denier, the higher denier being about twice the lower denier. Such staple fiber and precursor tows are preferably made by spinning filaments of different deniers, and collecting them in the same filament bundle on the same spinning machine, from orifices/capillaries of different diameters and/or throughputs.
