Abstract: A method for protecting and for restoring structural strength and substance to a concrete, fluid containing or conducting structure deteriorated to the condition of removal of substance of the concrete by sulfuric acids and like corrosive material in contact therewith is described by positioning a relatively thin thermoplastic layer of polyvinyl chloride or polyethylene, injecting a substratum of epoxy foam, polyurethane foam, or a combination thereof between the thermoplastic layer and the deteriorated concrete, and welding the foam to the thermoplastic layer. The product of the process is described.

Abstract: An apparatus and method for splicing photographic films is disclosed, where the films are conveyed along a path and supported by a track element. Upon being positioned to receive a splice, the films are clamped between a movable splice pad and the track element. The clamping action produced by the movable splice pad substantially eliminates the problem of film foldovers caused by curling at the trailing end of a film. A splice head is lowered to apply a splice tape to the films, thereby forming the splice. The films are spliced together in a flattened state, producing a continuous web of film which can be wound onto a roll or core for further processing.

Abstract: A method and an apparatus for edge joining of strip shaped plate or sheet elements of veneer (42, 48) by application of a hotmelt glue to at least one of the veneer edges to be joined and then forcing the elements (42, 48) together edge to edge before the glue solidifies, characterized in applying the glue in fully melted condition through heated nozzle means (40, 44) arranged so as to direct the applied glue as a jet or flow directly against a middle area of the relevant edge or edges is described. Preferably, the supporting area (2) for the opposite veneer strip (48) edge is located at a higher level (50) and preferably partly overhead the nozzle (40,44). By means of the described method and apparatus it is achieved that the total edge area of the veneer elements being heated, while gluing, is small, thereby not inducing any drying effect of importance on the veneer elements.

Abstract: An elongate light-shield film is withdrawn for a length corresponding to the width of a photosensitive film by a light-shield film supply mechanism, cut off into a light-shield film by a first cutting mechanism, and fed to an overlapping position by a feeding and positioning mechanism. In the overlapping position, a transverse end of the light-shield film is caused to overlap a longitudinal end of the photosensitive film, and the overlapping ends are cut off by a second cutting mechanism. Abutting ends of the light-shield film and the photosensitive film are then joined to each other by a tape, and the light-shield film and the photosensitive film which are thus joined are around on a spool. Debris produced when the overlapping ends are cut off is automatically discharged.

Abstract: A splicer for joining with tape the abutted ends of two sheets, such as the headers and footers of stacks of fanfold paper to be printed upon, is comprised of a clamp assembly and a tape dispenser. The clamp assembly captures the ends of the sheets between the resilient surfaces of a base and a movable top comprised of two spaced apart bars. Pins in the base help align perforated paper for joining. The dispenser runs along the slot between the two bars. It dispenses, presses down, and cuts the tape as it is laid along the butt-line between the ends of the sheets. An optional reversing bar causes the two sheets to travel along different shape paths to the splicer, thus enabling application of tape to the opposing sides of the sheets.

Abstract: Method and apparatus for heat-welding two members by applying radiation, such as infra-red radiation, through one of the members to enter layer(s) interposed between the two members. Method relies on inclusions through thickness of the layer(s) to be responsive to said radiation to raise temperature through thickness and promote bonds at inter-faces with surfaces of said members. The bonds are assessed using thermal imaging camera detecting a near visible radiation arising from the layer(s), which radiation is different from infra-red used for heating.

Abstract: The invention concerns a seaming tape for seaming carpeting and other flexible materials, and method of seaming carpet thereby. The seaming tape is reinforced by rigid strips so that the seam does not visibly peak, profile, or otherwise bulge visibly when the flexible material is placed in tension in a direction perpendicular to the seam. The seaming tape comprises an adhesive, a reinforcing scrim, a flexible backing, and rigid strips that are aligned parallel to the scrim, on opposite sides of the longitudinal centerline of the scrim, and spaced apart a distance from the centerline of the scrim. The rigid strips are sized and placed so that after a seam is made using the tape, the rigid strips are on opposite sides of the seam and aligned parallel to the seam. When the seamed material is stretched, the rigid strips resist flexure, resulting in a seam that stays virtually flat and invisible.

Abstract: A splicing coupling and a method using a splicing coupling is provided for splicing a pair of drip irrigation hoses. The splicing coupling has an inner and outer member. Each member has a heat activatable bondable surface opposite a non-bondable surface. Each member is circuitous. The inner member is formed with the bondable surface on the outside and the non-bondable surface on the inside, while the outer member is formed with the bondable surface on the inside and the non-bondable surface on the outside. Typically, the inner member is preferably bonded to the outer member along a bond line midway between the members and perpendicular to the longitudinal axis of the members. To form a splice, an end of a first hose is slid over the inner member but under the outer member until it abuts against the bond line. An end of a second hose to be spliced is slid over the other end of the inner member and underneath the outer member until it abuts the bond line.

Abstract: Increasingly stringent environmental restrictions make it challenging to apply coatings (i.e., paint) by conventional processes like spray painting because of the volatile solvents and hazardous pigments. The environmental scrutiny is particularly focused upon conventional corrosion protection surface treatments, especially chromated primers and conversion coatings. We apply appliqu{acute over (e)}s to provide a vapor barrier over the substrate to provide corrosion protection. We can make curved appliqu{acute over (e)}s on a family of molds of different Gaussian curvature and thereby avoid making a “splash” mold of the surface of interest to create the appliqu{acute over (e)}s. Using curved appliqu{acute over (e)}s reduces ridges, creases, or gaps that sometimes otherwise occur with attempts to a cover a surface with complex curvature with flat (planar) appliqu{acute over (e)}s.

Abstract: An embodiment of the present invention is a method for splicing together a pair of drop irrigation hoses using splicing means internal to the pair of hoses. The pair of hoses are joined in axial alignment to form a junction with the splicing means interposed internal to each hose. A splicing means is bonded to an inside surface of each hose to fashion the pair of hoses and splicing means into a unitary structure using means for fixing the splicing means to another surface. A seal is formed using means for sealing circumferentially at the junction to create a water-tight seal.
