Abstract: Production of strong lightweight membrane structure by applying a thin reflective coating such as aluminum to a rotating cylinder, applying a mesh material such as nylon over the aluminum coating, coating the mesh overlying the aluminum with a polymerizing material such as a para-xylylene monomer gas to polymerize as a film bound to the mesh and the aluminum, and applying an emissivity increasing material such as chromium and silicon monoxide to the polymer film to disperse such material colloidally into the growing polymer film, or applying such material to the final polymer film, and removing the resulting membrane structure from the cylinder.

Abstract: In a security system in which at least one fibre-optic wave guide, which is carried in a strand, extends along a boundary, light is directed into one end of the guide and the light leaving the guide is detected by an optical detector. An indication is given when the intensity of the detected light falls below a predetermined threshold, so as to warn when the wave guide is disturbed significantly or cut through.In order to manufacture the strand, a fibre-optic wave guide is positioned against an elongate carrier and secured to the latter by bonding agent and/or adhesive tape.A dummy strip, having identical external appearance to the strand but not including a fibre-optic wave guide, can also run along the boundary in question.

Abstract: Non woven fabrics are made by a method and an apparatus in which a preformed, planar set of adhesive coated or impregnated fill strands having a fixed orientation, spacing and tension of the fill strands is laminated to warp strands in the nip of pressure rolls.Adhesive lines are printed on a side of the warp strands opposite that engaged by the fill strands to prevent warp strands from hanging loosely from that side of the fabric.

Abstract: Tubular sheet material is produced by extruding a fluid polymer material through a hollow center die having an annularly extending extrusion orifice exit rotated about the die axis to form a continuous or discontinuous annular-form structure which is collected on a supported surface advancing through the hollow center of said die which surface at least in the zone of collection has a generally cylindrical shape concentric with the axis of die rotation. The collected structure undergoes attenuation because of the die exit rotation and, consequently, has a grain therein extending at an angle, e.g. helically, to the general extrusion direction. The collected structure may after solidification be slit and opened into sheet form or separated into filaments.

Abstract: The invention relates to a method wherein thin wires are three-dimensionally embedded in a uniformly finely undulating manner in the intermediate film of laminated glass by filaments of the same base material as the intermediate film with wire wound around them in stretched helical coil configuration being pressed into the film and made to disappear during the pressing procedure to form the laminate. Manufacture is simplified, economical and efficient. Also, better visibility conditions are obtained. The method is specially suited for the manufacture of heated panes for all kinds of transportation.

Abstract: A hot-melt adhesive line and an article of manufacture including the same are made up of one or more bundles of fibrous strands (49% by weight) and hot-melt adhesive to effect interfibrous adhesion after heated dispersion throughout the fibers of the strands. The line has an extruded outer layer of compacted adhesive to enclose the strands of the bundle and to adhere by uniform spreading of the entire strand onto a container surface. Typically, 1000 strands of man-made material are included in a hot-melt adhesive line that is 0.024 inch in diameter. Adjoined, side-by-side strands provide tape one-half inch in width.

Abstract: A reinforcement seal and tear tape or line is produced by a method wherein selected fibrous yarn is passed into a bath of hot-melt adhesive maintained at a desired temperature. The yarn is spread laterally and tensioned within the bath to cause the adhesive to penetrate and surround the fibrous yarn. The adhesive adhered to the yarn is extruded within the bath to controllably reduce the amount and cross-sectional shape of the adhesive coating on the yarn by contact with rollers, one of which is submerged in the adhesive bath or a die partly submerged in the adhesive bath. The yarn with an extruded adhesive coating thereon is then cooled by passing through a refrigerated cooling chamber after which the adhesive coating is formed into a desired shape by contact with a chilled-forming surface of superimposed rollers. Reels are then used to coil the coated yarn into spools.

Abstract: A monolayer tape for use in making up a multilayer matrix or composite which is bonded at a high pressure and temperature by pressing the composite between heated platens in air to cause densification, the tape consisting of collimated fibers held together by metal wire woven with and at right angles to the fibers, the wire being the same material as the matrix to become a part thereof when the composite is bonded. The aluminum matrix in which the fibers are embedded is provided by aluminum foils alternating with the collimated fibers in the multilayer matrix.

Abstract: A low density matting structure of improved transverse strength obtained by vertically laying continuous melt-spun thermoplastic macrofilaments (diameter=0.1-1.5 mm) onto a horizontally moving profiled support in overlapping rows of irregularly looped filaments to form a peak and valley three-dimensional structure undulating in its longitudinal and/or transverse directions. The matting articles consist essentially of the melt-spun filaments which are self-bonded or fused at random points of intersection without using any bonding agent or reinforcing inserts, and the resulting matting is especially distinguished by a high transverse strength per unit of surface weight of at least 2 Nm/g and preferably 4 Nm/g.

Abstract: Track belts designed to fit circumferentially around a pneumatic bladder or tire carcass can be sealed against the ingress of soil and rock between the track shoes attached about the outer periphery of the belt by forming individual and permanent flat sites on the outer circular periphery of the belt so the flat undersurface of each track shoe is nested on a flat shoe site and therefore does not have triangular shaped gaps under its leading and trailing edges. A transverse rib of elastomer, raised from the surface belt between each of the adjacent flat sites further seals the belt in the narrow gaps formed between adjacent track shoes thereby preventing the ingress of soil and rock in these gaps when the shoes pass through a footprint formed as the pneumatic supported system is rolled.
