Abstract: Mechanical goods made of rubber-like material, such as belts, hose, and the like, are reinforced with stitch-bonded web fabric.This invention relates to mechanical goods made of rubber-like material reinforced with a stitch-bonded web fabric.Mechanical rubber goods such as conveyor belts, hose, power transmission belts including V-belts and timing belts, snowmobile tracks, and the like, require reinforcement to achieve sufficient strength, rigidity, dimensional stability, and durability. Classically such mechanical rubber goods have been reinforced with various types of woven fabrics, mostly plain woven. More recently attempts have been made to use non-woven or scrim fabric but these generally increase the performance of one property at the expense of another. This is also true when it is attempted to use felts or spray-bonded fabric. Examples of prior disclosures of the use of non-woven fabric in rubber goods are U.S. Pat. No. 3,312,584, Charlton et al., Apr.

Abstract: Shaped articles such as tiles and panels are produced from calcium aluminate cement motars by casting in a mold with a glossy water-repellent synthetic polymer surface to yield castings with highly reflective glassy surfaces. The calcium aluminate layer need only be several mils thick with the rest of the mold volume being filled with other cementitious compositions. Color pigments may be added to the calcium aluminate slurry to yield castings with brilliant glassy colored surfaces.

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 woven structure comprising at least a continuous band around an internal axis, suitable for impregnation with resin or for internal deposition of graphite from a reactive vapor, comprises axial threads, circumferential threads, and radial threads. The device employed to produce the structure comprises principally a series of flat rings or disks, aligned and slightly spaced from each other axially, having small apertures located around their circumference or one or more helical worms, with central openings, whose successive turns are similarly provided with apertures. Radial threads are passed through homologous apertures in successive disks, or successive turns of the helical worm, and are then drawn toward the central axis by wrapping of circumferential threads around them in the axial space between adjacent disks. Axial threads are then passed between the radial threads, and are drawn by further wraps of circumferential threads.

Abstract: Adhesive joining system for joining a plurality of superimposed material layers. An elongated needle-like member is reciprocally and rotatably driven along and about its longitudinal axis so that each reciprocation causes the needle to pass through and be withdrawn from the superimposed layers. After the needle has passed through the layers, at least the outer tip is coated with an adhesive material. The adhesive material itself may be in solid, liquid or powdered form and be either heated or unheated. After coating, withdrawal of the needle from the material layers causes the adhesive on the needle to be deposited on the material through a wiping action caused by the pressure of the material exerted against the needle. Rotation of the needle-like member gathers loose fibers from the material layers and wraps them together in the adhesive to form a reinforced joint.

Abstract: A panel having a double wall construction of a structural plastic material is provided with improved thermal insulative properties by (1) metallizing at least one surface of each wall of the panel with metal such as silver to provide a light reflective surface and to produce a partial barrier to atmospheric gases, (2) coating the metallized surface with a barrier plastic such as vinylidene chloride polymer, (3) evacuating the space enclosed by the walls of the panel, and (4) adding to the evacuated space a gas-absorbing material.

Abstract: A panel is provided having two metallic sheets separated by an insulating core, in which a portion of each of the metallic sheets extends beyond the insulating core to form sheet ends, a unitary metallic member is joined to one of the sheet's ends, and insulating means are provided to both thermally and electrically insulate the sheet ends from each other. The unitary metalic member has a joining surface including a flange designed to be fastened to a corresponding flange of a like panel end structure to form a joint which is recessed with respect to the metallic sheets, and which maintains thermal and electrical insulation between the two metallic sheets of each panel.

Abstract: The invention provides for repairing a crack in a pane of plate glass caused by the impact of a hard object without removing the glass from its location by cutting out a section from the glass surrounding the crack and replacing it with a disc of a similar sheet of glass.

Abstract: A face plate suitable for use with an acoustical-optical image tube is disclosed and its method of manufacture. A fused glass capillary array which constitutes a disk having a large number of smooth parallel passages or pores therethrough is metalized, preferably by an electroless plating process, whereby the inside surfaces of all the pores are coated. The resulting layer of gold, silver or platinum may then be increased, if desired, by further plating, after which the disk is cleaned, heated to approximately 470.degree. C. and the pores filled with a sealant such as silver chloride. One or both surfaces may then be lapped to provide a disk having a glass surface but with many conducting cylinders extending therethrough which then appear as rings on the surfaces.

Abstract: A Christmas Tree formed of collapsible sections of trunk and branches with electrical lights mounted in sockets on each branch. Electrical conductors run from a portable supply cord joining the base of the trunk through the trunk and branches with the individual sections of the tree joined together by plug and socket fittings that form both mechanical and electrical connection of the joined members. The top section of the trunk is fitted with a spring-biased member that rests against a ceiling to hold the trunk in a vertical position, with the base of the trunk resting on the floor or other support surface. A multi-pole switch is fitted on the portable supply cord for switching various combinations of tree lights.

Abstract: Improved placement apparatus comprises a compliant backer sheet, e.g., formed of foamed polyvinyl chloride, and a clear transparent overlay sheet, e.g., of vinyl, disposed over the backer and secured on three sides thereto, as by thermowelding, to fuse the contiguous backer and overlay plastic materials.A graphics sheet desired by a consumer, e.g., a wallpaper or fabric segment, is inserted between the backer and overlay, and enclosed by securing a flap-like member affixed to the overlay to the backer sheet. A double sided acrylic copolymer adhesive strip is advantageously utilized to secure the flap and backer sheet.

Abstract: A plurality of corrugated sheets are fixedly superimposed one on another so that the axes of the corrugations of one sheet are not parallel to those at adjacent sheets.

Abstract: Upon a substrate containing different zones which are to be connected with one another, there are successively deposited a layer of thickness e.sub.1, of a first metal (tantalum) oxidizable by heat treatment, and a layer of thickness e.sub.2 of a second metal (aluminium) non-oxidizable by said treatment, deposited upon the surface of the first layer in accordance with the desired connection profile. The thickness of the aluminium layer is controlled so that it is equal to the increase in thickness of the tantalum layer as a consequence of the transformation of the tantalum into tantalum oxide.

Abstract: An automated process of making reinforced roof and wall sheets for trucks and trailers employs step-by-step advancement of the sheet stock and lateral infeed of the structural reinforcing members. As the reinforcing members are sequentially fed into registry with the sheet stock, two kinds of adhesive are applied to them, one being a hot melt adhesive and the other being a catalyzed room temperature curing adhesive. The hot melt adhesive sets to provide an initial bonding which allows normal handling while the room temperature curing adhesive cures in the joint ultimately to augment the hot melt and provide a high strength joint.
