Abstract:
A double containment pipe fitting and method of making same is disclosed. The fitting includes a branch double containment pipe section butt welded to a double containment pipe header, or main section to form a fitting wherein the branch section extends away from the header section. The header and branch section primary and secondary pipe portions contain distinct engagement surfaces which are joined together to form the fitting. A unique, non-planar heating element having opposed heating surfaces is brought into contact with the main and branch pipe sections to soften the plastic for welding purposes which are then joined together in a manner such that the respective centerlines of each pipe section intersect.
Abstract:
A radiation-curable release composition is disclosed which comprises:(A) an organopolysiloxane represented by the formulaRSi(CH.sub.3).sub.2 --O--(Si(CH.sub.3).sub.2 O).sub.n (Si(CH.sub.3)(R)O).sub.m Si(CH.sub.3).sub.2 R (I) wherein in Formula (I), each R is --R.sup.1 --O(O)C--C(R.sup.2).dbd.CH.sub.2, --R.sup.1 --O--C(R.sup.2).dbd.CH.sub.2 or is derived from an organic molecule containing both ethylenic unsaturation and epoxide functionality; R.sup.1 is a hydrocarbylene group; each R.sup.2 is independently hydrogen or a methyl or ethyl group; m is a number from about 1 to about 15; and n is a number from about 50 to about 300; and(B) an organosiloxane copolymer represented by the formula(R.sub.3 SiO).sub.x (SiO.sub.4/2).sub.y (II) wherein in Formula (II), each R is independently a hydrocarbon group or a group represented by the formula--O(O)C--C(R*).dbd.CH.sub.2 wherein R* is hydrogen or a methyl or ethyl group; x is a number from about 0.25 to about 75; y is a number from about 1 to about 56; and the ratio of x to y is from about 0.3:1 to about 1.5. In one embodiment, the inventive release composition further comprises(C) an acrylate represented by the formulaCH.sub.2 .dbd.C(R**)--C(O)O--R.sup.2 (III) wherein in Formula (III), R** is hydrogen or a methyl or ethyl group, and R.sup.2 is a hydrocarbon group of about 10 to about 24 carbon atoms. A method of producing release-coated substrates, the release-crated articles thus produced, and multi-layer articles or constructions incorporating a release layer also are disclosed. When the release compositions are cured such as by radiation, the cured compositions exhibit a desirable high and controlled release force at high speeds such as the speeds utilized in label processing.

Abstract:
A toy or model vehicle having ground wheels, of which at least one is formed with a cam or lobe that cooperates with a pivotable or reciprocable member mounted in the vehicle, or with an intermediate member transmitting such motion, whereby such items as simulated engine pistons, toy figures of animals and men, and gun turrets, for example, may be given movement during travel of the vehicle over a surface.
