Abstract: A form clamp particularly useful in construction environments for clamping two side-by-side forming panels is provided. The form clamp includes a frame having a first jaw and a slider having a second jaw opposed to the first jaw. The slider is shiftable along the frame, and at least one includes a locating pin configured for receipt in holes in forming panels.

Abstract: A method of consolidating a tubular composite article of polymeric matrix material and fibrous reinforcing material, comprising enclosing a length of the tubular composite article in a tubular protective member and advancing the protective member to carry the length of the article thus enclosed through a consolidation zone wherein the article is progressively subjected to consolidating temperature and pressure. The method enables the composite to be pulled through the consolidation zone without the distortion which tends to occur in standard "pultrusion" methods owing to surface friction and longitudinal tension on the composite.

Abstract: First and second bodies of heat recoverable polymeric material are fusion bonded together with their directions of recovery at an angle to each other, the bond preferably being cross-linked after bonding to enable the resulting article better to withstand the recovery forces encountered in use. The invention is especially useful for making wraparound tubular enclosures for "T"'s and bends which enclosures in use will recover radially about two tubular axes.

Abstract: A process for the production of a marker sleeve assembly which comprises deforming a substantially non-cross-linked web of polymeric material at a temperature below the crystalline melting point or softening point of the material to render the web heat-recoverable, fusing together parts of the web or parts of the web and at least one other polymeric web to define a plurality of radially inwardly heat-recoverable marker sleeves, disposed in side-by-side relationship and preferably separable and subsequently cross-linking the resulting assembly.

Abstract: A process for the production of a heat-recoverable wraparound closure having a closure means along at least one of a pair of opposed edge regions thereof which includes the steps of fusing together substantially non-cross-linked parts of a polymeric material which is or may be rendered heat-recoverable, or a substantially non-cross-linked part or parts of said material and at least one other substantially non-cross-linked polymeric material to produce the configuration of said closure means and subsequently cross-linking the substantially non-cross-linked polymeric material.
