Abstract: A method of making electrical connections between large-scale integrated cuit boards or the like using a plastic adhesive charged with conductive particles. The method includes the steps of: coating one board with the adhesive, placing another board on the adhesive coating, applying a field to make the conductive whiskers align perpendicular to the boards, and hardening the adhesive while the field is applied. The field may be electric or magnetic, depending on whether the whiskers are paramagnetic or ferromagnetic.

Abstract: Apparatus for and method of manufacturing a heat insulating material from an uncured, strip-shaped felt of fibres containing a heat hardenable bonding substance firstly form corrugations extending across the entire width of the uncured felt and following one another in succession along the length of the felt. The corrugated felt is then cured as a cured felt containing fibres extending in a serpentine array along the felt, and conveyed along a path of travel extending past a cutter having a cutting blade extending transversely across the path, whereby the felt is cut longitudinally into two partial felts, the corrugations being severed so that the fibres form U-shaped arrays disposed in succession along each of the partial felts. This fibre array provides compressive strength combined with flexibility, enabling the insulating material to be used on various pipe sizes.

Abstract: The specification discloses a reinforcing fabric for concrete or the like and a method for making the same in which stirrup members are joined to the fabric by rigid joining members such that the stirrup members are retained generally in the plane of the fabric. The joining members are bendable, however, such that the stirrup members can be rotated to an erect position projecting away from the plane of the fabric. In an alternative embodiment, individual stirrup projections are joined to the fabric and are made of rigid but bendable materials so that they can individually be bent out of the general plane of the fabric.

Abstract: Laminated material comprises two spaced sheets, one having perforations and one being plain, the sheets being connected by heat conductive portions. Cooling fluid is passed through the perforations, impinges on the plain sheet and then passes between the sheets to discharge from the end of the laminate.

Abstract: An electrical connector in which conductive rubber rods are mounted in a nonconductive substrate. The rods extend above and below the upper and lower surfaces, respectively, of the substrate for electrically interconnecting conductive traces on a pair of electronic components, such as a display panel and logic circuit used in a digital wrist watch. A method for making the connect is disclosed.

Abstract: A snow ski having a plastic foam core formed in situ between preformed top and bottom subassemblies.

Abstract: A process for producing a flocked fabric laminate by coating an auxiliary substrate with a temporary adhesive binder, flocking the coated auxiliary substrate with flock fibers, coating the flock fibers with a curable flock adhesive binder, marrying a substrate backing layer to the binder coated flock, permanently setting the flock adhesive binder, and then removing the auxiliary substrate from the fabric laminate whereby the flock remains secured to the substrate backing layer is disclosed. Flocked fabric laminates obtained by such method are also described.

Abstract: A process for producing a laminate by coating a continuous first layer of a film forming material onto a release sheet, distributing flock fibers uniformly onto the first layer, drying the first layer to form a film and secure the flock fibers thereto in a substantially upstanding position, coating the tips of the flock fibers with a flock adhesive, marrying the flocked film to a substrate backing layer such that the coated tips contact the said substrate layer, permanently setting the flock adhesive, and then removing the release sheet. Laminates obtained by such method are also described.

Abstract: A lightweight, reinforced structural material, having low density and high flexure and compression strengths, is prepared by combining together inorganic cementitious material and organic polymer-forming material to form a mixture and forming the mixture into a slab while embedding an elongate reinforcing members which are relatively rigid in the depth dimension of the slab. Polymerization and setting of the material tensions the reinforcing members.

Abstract: A tube of weldable sheeting for the production of carrier bags comprises first and second tube wall portions extending longitudinally of the tube in circumferentially spaced relationship. Alternating ribs and bands, extending longitudinally of the tube form together each of the first and second tube wall portions, each of the ribs being of lesser width and greater thickness than each of the bands. Third and fourth tube wall portions extending longitudinally of the tube are integrally connected to the first and second tube wall portions so as to form a tubular formation together with the first and second tube wall portions, the third and fourth tube wall portions having a thickness corresponding approximately to 1/4 of the sum total of the thicknesses of one of the ribs and one of the bands.

Abstract: An assembly of hollow fibers for use in fluid treatment apparatus and apparatus incorporating such assemblies, in which a primary frame is provided with a central window defined by edges at least two of the opposite edges being thinned down to form hollows. A web of hollow fibers is placed in the hollows and is secured in place, and the fibers secured to one another, by a mass of hardened resin material in at least one of the hollows.The assemblies are mounted in a container, through which a first fluid is caused to flow, the fluid passing around the fibers and through the windows before leaving the container. The interiors of the hollow fibers are connected to the exterior of the container so that either fluid permeate flows out of the apparatus via the interiors of the fibers or a second fluid is caused to flow through the interiors of the fibers if some form of fluid exchange is desired.

Abstract: A multi-ply woven article has stiffening elements positioned within pockets formed by double plies of the article to provide the article with substantial strength and rigidity. The double plies may comprise a generally parallel pair of rib plies which extend between the opposite faces of the article in generally zig zag fashion to form a plurality of intermediate rib portions, or a pair of generally parallel, spaced apart face plies forming each of the opposite faces of the article, or both. The various stiffening elements may comprise one or more layers of relatively stiff material. The various layers comprising each stiffening element may comprise unidirectional fibers or materials oriented relative to the woven article so as to impart maximum strength in selected directions.

Abstract: A multi-ply woven article has elements positioned within pockets formed by double plies of the article to provide the article with desirable acoustical properties as well as considerable strength and rigidity. The double plies may comprise a generally parallel pair of rib plies which extend between the opposite faces of the article in generally zig zag fashion to form a plurality of intermediate rib portions, or a pair of generally parallel, spaced apart face plies forming each of the opposite faces of the article, or both. Some of the pockets formed by the double plies are filled with acoustical elements having a selected number of holes of appropriate size so as to pass sound waves therethrough at a controlled rate, while still other pockets are filled with non-acoustical elements which are generally impervious to sound waves.

Abstract: A double-walled vessel wherein a grid is located between the walls to provide a support for the inner wall, the grid being made up of strips which are on edge and which define interconnected cells for passage of a fluid between the walls.
