METHOD OF BONDING PLASTIC PIPES

... 7566-959 The invention relates to a method of bonding plastic pipes by inserting a plastic pipe into a plastic joint and melt-bonding them together, which is a so-called socket bonding method. The inner circumferential surface of the socket portion of a plastic joint is tapered so that the socket portion becomes progressively smaller in diameter in a direction away from its end portion, or the outer circumferential surface of the end portion of the plastic pipe is tapered so that the end portion becomes progressively smaller in diameter towards its insertion end. When the end portion of the plastic pipe is to be heated, the length from its insertion end of the part to be heated is made nearly equal to the final insertion length of the pipe. When the socket portion of the plastic joint is to be heated, the length from the socket end of the part to be heated is made shorter than the final insertion length of the pipe by a predetermined distance.

Structural Composition and Method

A structural polymeric composite includes a stiffening layer. The composite is made in a continuous extrusion process in which the stiffening layer is pulled through a cross-head die as a polymer is extruded over it. The layer includes a film or textile carrier, a filler of carbon fibers, fiberglass, organic fibers or minerals forming a mat. A binder may be dispersed over the mat and a second carrier applied. The mat is subjected to heat and pressure to soften the carriers and binder so they penetrate into the interstices of the filler and binds mechanically with them and the carriers and binder bind chemically with each other to form the stiffening layer. A polymer is then extruded over the stiffening layer, which may be used flat, provided with holes or punches for composite action with the polymer, formed into a profile, or segmented to provide spaced-apart stiffening layers.

Perform extended finish for processing light weight ecologically beneficial bottles

Disclosed are preforms which incorporate improvements in the region of the neck and upper segment of the body to allow the production of lightweight containers, such as bottles suitable for containing water or other beverages.
