Abstract: Inorganic fibrous pipe insulation in the shape of a tube comprising outer and inner flexible sheets on the outer and inner cylindrical surfaces of the tube. A majority of the fibers are at right angles to the flexible sheets and therefore extend radially of the pipe to offer good compression resistance to impact. By using substantially non-stretchable material for the inner sheet a fibrous layer whose fibers are generally perpendicular to the layer can be permanently formed into generally cylindrical shape. For insulation designed to cover very small diameter pipes the thickness of the fibrous layer is varied to provide fewer adjacent the inner flexible sheet than are adjacent the outer flexible sheet.

The method includes the steps of providing a first, relatively thin dielectric substrate portion having an antenna element formed on a surface thereof; providing a second, relatively thick dielectric substrate portion; shaping and securing the second substrate portion to the curved surface; and shaping and securing the first substrate portion and the antenna element to the second substrate portion. The method permits a microstrip antenna, or other thin structure supported on a substrate, to be mounted to curved surfaces of even short radius or curvature (e.g., less than four inches) in full conformity therewith without damaging the thin fragile antenna element.

Abstract: A heat-recoverable wrap-around sleeve for pipe protection, with a patch-type closure.The patch is heat-stable and comprises two polymeric layers bonded together through, for example, an open mesh glass-fibre fabric. No separate adhesive is required.The hot modulus of one of the layers is low enough to enable it to bond to the overlapping edges of the wrap-around sleeve, and the hot modulus of the other layer is high enough to withstand installation temperature.This new patch is easier to install and requires less materials than prior art patches, and does not need to be bonded to the sleeve in such a distinct heating step.

Abstract: A method and apparatus for creating an identification sleeve on a thin, elongate object (35, 67, 113), such as a wire, pipe or ring, is disclosed. A printer (15, 65, 91) prints identification indicia on a strip of ultrasonically weldable heat shrinkable material (13, 63, 93). The strip is cut into flat pieces (13A, 63A, 93A), each of which contain identification indicia in a predetermined location, preferably at the center of the piece. The pieces are wrapped around the elongate object to be identified such that the indicia overlies the object and the longitudinal axis of the indicia lies generally parallel to the longitudinal axis of the object. The pieces (13A, 63A, 93A) are wrapped around the object such that the pieces take on a U-shaped configuration. The outwardly extending legs of the U-shaped pieces are ultrasonically welded together adjacent to the object and the excess portion of the legs are cut away. Then the thusly formed sleeve is positioned by sliding it along the object.

Abstract: To apply a cover plate on a printing cylinder, particularly to prevent corrosion of the cylinder surface, a double-side coated adhesive foil (2) is applied to a cover plate (1, 36, 65) which is wrapped about the cylinder, so that the cover plate will be adhered to the cylinder by the double-side coated adhesive foil. To install the cover plate, the cover plate (1) with the adhesive foil applied on one side, and, upon removal of a protective strip (S), is first placed in a clamping groove (34, 47, 65) of the cylinder, temporarily secured therein to provide for the adhesive to retain maximum adhesion strength, then wrapped about the cylinder, for example by a resilient pressure roller (40) while stripping off the protective strip (S) from between the cover plate and the cylinder; the end portion of the cover plate, which is left free from adhesive foil, is then wrapped about the trailing edge (52) of the groove, angled against the groove wall, and there adhered by a liquid or contact adhesive.

Abstract: A process for making a moldable article for individualizing the operative surfaces of implements such as the hand grip of tennis racquets or hand tools. The moldable article is a sheet of polymeric material, including a polyurethane or thermoplastic-rubber copolymer component blended with volatile solvents and fillers to form a moldable mass that after receiving an individual's hand impression, for example, cures by solvent evaporation at ambient temperatures to a solid non-tacky hand grip. The moldable article is made by mixing the components together and forming a sheet which is sandwiched between semipermeable films that permit partial evaporation of the solvents. The sheet is then packaged between non-permeable films which prevent further evaporation until impressed by the consumer and exposed to air drying.

Abstract: The two halves of a split annular inflatable brake are formed by laying up a number of flat rubber body plies and interleaved end patches which extend longitudinally beyond the ends of the body plies. The sides of the body plies, some of which are fabric reinforced, are successively folded over each other and stitched to form a multi-layered flattened tubular body. The end patches are folded in turn over the ends of the flattened tubular body, and in the case of fabric reinforced patches, are pinched and trimmed along the side edges of the flattened tubular body. Unreinforced end patches are cut inward from the sides to form a center flap which is folded down against the sides of the flattened tubular body and side flaps, one of which is removed, and the other of which is pulled circumferentially around the tubular body over the folded center flap. The split air brake is built up on an arcuate mold half and then the remaining mold parts are assembled around the built up part for curing.

Abstract: For all-over lining of a longitudinally slit pipe insulating shell consisting of mineral fibers, with a foil having a coating of a heat activatable adhesive, a fully automatic process uses the steps of bringing the foil into a preliminary position with its end portion bent over downwardly by means of a rail, subsequently moving the foil into a position of readiness in which its outer edge comes to bear on a vertically adjustable heating roller, so that an initial activation of the adhesive starts to take place, then raising the heating roller to the pipe insulating shell and permitting it to remain in this adhering position for a brief period, and finally carrying out the actual lining operation by rotating both the heating roller and the pipe insulating shell at the same peripheral speed, and in opposite direction by means of a winding mandrel.

Abstract: A method of constructing a collapsible mandrel for use in fabricating filament wound vessels or tanks includes the steps of preparing a rigid mandrel and supporting the mandrel on a rotatable axle, applying one or more layers of strips of rubber longitudinally on the mandrel to form an enclosure, applying coats of rubber solution over the layers, winding a layer of fibers over at least one of the layers, and curing the rubber layers. The layers are cut into two parts, removed from the rigid mandrel, and rejoined by using reinforcing straps along the seam of the joined parts. The collapsible mandrel may be used to fabricate either filament wound tanks or other collapsible mandrels, neither of which would have a seam or joint since, after constructing the tank or second mandrel on the first inflated collapsible mandrel, the first mandrel would be deflated, collapsed and removed from the interior of the tank or second mandrel.

Abstract: An apparatus for applying labels to cans of a straight or substantially frustoconical design is disclosed. The apparatus uses an elongated track for supporting one edge of the can and a single belt extending longitudinally above the track and adapted to selectively engage an edge of the can to rotate and advance the can along the track. Movement of the can transverse relative to the track is restrained by retaining the can against a pair of spaced, longitudinally extending nonmagnetic guide surfaces. The can is retained against the guide surfaces through magnetic attraction of the can by a series of magnets positioned intermediate of but offset from the guide surfaces. As the can moves along the track, a suitable label is affixed to the surface of the can.

Abstract: An ablative thermal barrier on the interior surface of a cylindrical combustor is made by first molding a silicone rubber strip with shaped edges. The strip is then laid inside the combustor so that it runs circumferentially either as a helix or as a series of circles. The adjacent turns are spaced apart by a gap into which is interposed a thermosetting polymer material. The rubber is then pressed radially outward so that the adjacent turns are caused to press laterally against each other. The thermosetting material is then cured while in its resultant compressed condition, to make the material into a circular or helical rib which better retains the rubber in place during use.

Abstract: In order to apply "hot melt" adhesives to thin plastic film labels for glass containers without distorting the labels, a "hot melt" adhesive which is thixotropic is melted at 350.degree. F. and is continuously worked to maintain its viscosity at a fairly low level while being cooled to about 110.degree. F., at which time it is applied to the label. The label is applied to the glass bottle and the resultant labeled bottle will have the property of being able to withstand pasteurization temperatures, as well as refrigeration temperatures, without having the label separate from the bottle.
