Abstract: Elements are supplied to a work station with the elements being arranged in a row. The elements are releasably retained at the work station. The articles to which the elements are to be transferred are moved through the work station with the row of elements at the work station extending in the same direction as the direction of article movement. Each of the elements is transferred to an associated article as the articles are moved through the work station. The elements are sequentially transferred with the most downstream element always being the next element to be transferred.

Abstract: Means and method for preventing distortion in ultrasonic pattern rolls used for quilting layers of thermoplastic material by ultrasonic energy, whereby uniformity of seal quality is maintained. The method contemplates the distribution of heat generated in the roll during warmup over the entire mass of the roll to eliminate distortion from true cylindrical shape, whereby the tendency of the roll to bow out of round resulting in high and low areas with each revolution and the formation of correspondingly uneven welds is eliminated.

Abstract: An apparatus for in situ preparing and applying foam to a surface, such as a roof, and at the same time applying a membrane onto the surface of the foam, produces a foam-membrane sandwich having an upper surface of controlled smoothness and thickness or pitch, which sandwich is firmly held to the treated surface. The apparatus is normally self-propelled and may be automatically controlled so as to be advanced across the surface to be coated with membrane-covered rigid polymeric foam, preferably of polyurethane foam, as the curing pre-foam and covering membrane are applied. In preferred embodiments of the invention the membrane is a roofing felt or fiberglass web, mat, treated paper or cloth fed from the apparatus from a roll thereon, producing with the roof or other surface to be coated, a form into which a curing pre-foam is deposited as the apparatus is advanced.

Abstract: Apparatus for and method of attaching a strip of a first material having a hot melt adhesive on both sides thereof to a second web of material. A web of first material is advanced toward and through a cutting station a distance substantially equal to the width of the strip to be formed therefrom and a strip is cut from the end of the web. The cut strip is held on the moving cutting member and is transferred to an anvil on a rotary transfer drum while the drum is stationary. The transfer drum is then rotated, with the strip on an anvil thereof, to a tacking station where a second web of material is supplied at a substantially constant velocity. The strip on the anvil is moved through the tacking station at a velocity substantially equal to the velocity of the second web and is brought into contact with a first surface of the second web.

Abstract: A method and apparatus for splicing two rolls of tire cord fabric in axially aligned relation. A plurality of splicing rods are forced through overlapped ends of the rolls from opposing longitudinal sides of the fabric. The splicing rods are guided through the overlapped ends at successive points spaced along parallel lines angularly disposed to the parallel warp cords of the fabric and alternately pierce and pass through the pieces of fabric from the farthest spaced faces of the overlapped ends. The splicing rods are firmly snubbed together and held in position by the coaction of the warp cords and weft threads of the fabric, as the fabric is tensioned.

Abstract: A method of constructing a model tree structure and the article resulting therefrom constitute the present invention. First a full three-dimensional pattern is constructed from wire and tin-lead. The pattern is then partially flattened and placed in a rubber mold. The mold is filled in around the pattern with rubber and the entire mold with the pattern in place is heated to vulcanize the rubber and form a mold cavity conforming to the configuration of the pattern. A casting metal is provided which preferably is at least 98% lead. Up to 2% antimony may be added to increase flow characteristics. It is also permissible to include a quantity of tin. The part is cast in the mold using centrifugal casting techniques. After the part has solidified and been removed from the mold it is bent into full three-dimensional form corresponding generally to the initial shape of the pattern.

Abstract: There is described a method for road surface marking with tape material, including the steps of forming an essentially bituminous primer layer on such surface and then pressingly laying a prefabricated tape material on said primer layer, such layer being formed with an essentially thermoplastic composition containing at least 60% by weight of solid thermoplastic substances fluidified for intimately contacting the road surface. The layer is capable of quickly solidifying to a viscosity of at least 10.sup.3 - 10.sup.4 cP for receiving the tape material and then up to at least 10.sup.5 cP within 30 seconds to provide a bond between the tape and said surface capable of resisting horizontal stresses of at least 1.5 Kg/cm.sup.2. Thereafter, the later further hardens at ambient temperature resist to a stress of at least 3 Kg/cm.sup.2. There are also described devices for applying such composition and tape and for melting the said solid thermoplastic substances.

Abstract: A method of protecting surfaces against deterioration by environmental factors is described. In a particular aspect of this invention a metal surface subject to electrochemical corrosion has applied to it a metal-plastic laminate comprising (a) a foil of corrosion-resistant metal, in particular lead; (b) a plastic film ranging up to about 20 mils in thickness, bonded to one surface of the metal foil, either by "extrusion coating" or by means of a suitable adhesive; and (c) a coating of pressure-sensitive adhesive on the opposite surface of the metal foil. (In some cases the outer plastic film can be omitted.) The laminate is bonded to the metal substrate by means of the pressure-sensitive adhesive. This method, when used in conjunction with a coating of anti-fouling paint, is effective for protecting the hull of a marine vessel both against corrosion and fouling by marine organisms such as barnacles; and the invention is also effective in protecting wooden vessels against marine borers.
