Abstract: Disclosed is a method and apparatus for forming a joint in a confined space between two abutting ends of conduit liners. In the method, an excavation is formed to provide access to a buried conduit. Thereafter, the conduit is opened and cleaned of debris and elongated sections of conduit liner are inserted through the opening into the conduit in opposite directions from the opening. Once insertion is completed, a sleeve is positioned concentrically around one of the conduit section ends. The ends of the sections are positioned in an abutting coaxial relationship and are aligned and attached together by tape. The sleeve is then moved to a position overlapping the intersection of the two sections and the annular space between the sleeve and the exterior of the conduit sections is closed by sealing with foam rubber stripping constrained by tape. A polyurethane material is injected through a port in the sleeve to fill the annular space. Thereafter, the polyurethane material is allowed to set.

Abstract: The present invention relates to a method of treatment on the surface of copperfoil mainly used for printed circuits. More particularly, it relates to a method of electrodeposition of a binary alloy consisting of zinc and tin as a barrier layer against copper migration into an adhesive substrate during subsequent heat press lamination, while a binary alloy on copperfoil is converted to ternary alloy defusing into copper by heat press lamination resulting in a layer of Cu-Zn-Sn, ternary alloy. This layer prevents spottings on the etched surfaces and provides high resistance to hydrochloric acid, and better adhesion than hitherto used alloys.

Abstract: An improved process for mending clothes with a unique means for applying a thermoplastic synthetic resin to form a strong border between a basic cloth and a mending cloth. The resin is applied to both the mending cloth and the basic cloth before fastening them together. The cloths are then temporarily fastened together. The mending cloth is placed over the torn portion of the basic cloth and a hole is stamped through the two cloths. Additional resin is applied to the circumference of the hole and the piece of mending cloth which has just been cut out is manually pressed into the hole. A reinforcing cloth is placed on the back of the mended area and an iron is used to heat the resin and cause the various pieces of cloth to adhere. The mended area is difficult to distinguish and resists tearing or fraying.

In this application process, a foamed thermo-plastic thermal insulating material is bonded with a membrane having a tacky compound layer on one surface thereof so that the tacky compound layer is in close contact with the foamed thermoplastic material, without causing any damage due to heating, and a built-up roofing or waterproofing is formed on the other surface of the membrane according to the conventional application process.

Abstract: A method of making a non-slip plastic film comprises extruding separate plasticized plastic materials in two streams so that one stream abuts against and adheres to the other to form a combined plastic layer. The combined plastic layer is then stretched by directing air centrally into a tubular formation of this layer. One of the plastic materials comprises a material having an expanding agent or a foaming agent and the stretching causes the breaking of the voids of the foam plastic to form a rough, irregular net-like formation on the exterior of the other plastic. The apparatus includes two separate nozzles arranged to extrude plastic material so as to intersect and form a combined plastic.

Abstract: A compact machine for measuring, cutting and applying insulation blanket material onto sheet metal workpieces as they flow along a conveyorized lower line. The blanket material flows along an upper path. A flying shear mechanism, which travels a short distance along this path, is driven downstream when the trailing edge of a workpiece is sensed. Rack and sector mechanism brings the shear to an incisive stop at its downstream cutting position when the shear blade strikes its cutting block; hence the kinetic energy of the downstream movement is utilized for shearing. The shear remains in downstream position, to serve as a gage for starting the blanket material, until a sensor in the lower flow path senses the leading edge of the next sheet metal workpiece; this raises the shear blade and moves the shear mechanism to upstream position. A pneumatic system accurately times the cut-off mechanism to match the shearing of the blanket material to the length of the workpiece, leaving a margin if desired.
