Compositions of this invention, which are rendered semi-conductive by the addition of carbon black thereto, are especially useful as outer layers bonded to layers of crosslinked olefin polymer insulation of electrical conductors.

Abstract: Multi-phase paste and liquid polish compositions having improved gloss life and water resistance durability are obtained by providing an oil external emulsion phase containing aminofunctional polysiloxane, and a water external emulsion phase containing dimethyl polysiloxane. The oil external emulsion phase and the water external emulsion phase are packaged in the same container or in separate containers in a manner as to keep each phase separate from the other phase until the polish compositions are applied to a surface to be polished. The method of preparing and packaging the multi-phase polish compositions is also disclosed.

Abstract: Water-curable, silane modified ethylene polymers produced by reacting an ethylene polymer having a density of 0.875 to 0.930 gram per cc with a silane having an acryloxy moiety. The water-curable silane modified polymers, having improved properties, are particularly desirable as extrudates about wires and cables.

Abstract: A valve assembly has an outer body with an internal passageway for gas containing a valve seat and a valve member which can be lifted from the valve seat by rearward pressure. An inner body is threaded in the passageway, and itself includes an internal passage and a plunger within the passage. The plunger has a forward hollow sleeve portion and two arms extending rearwardly at diametrally opposite positions, the arms being linked at their rearward ends by a bridge from which extends an activating member adapted to hold the valve member away from the valve seat. The plunger has a sealing member forwardly of the activating member for closing the internal passage when the plunger is in a forward position. The inner body has two opposed grooves to receiving the arms, thus interlocking the plunger and the inner body so that rotation of the one requires rotation of the other. The bridge portion can be engaged by a forked tool for rotating it.

Abstract: A process of modifying ethylene polymers by reacting granular ethylene polymers having a density of about 0.87 to about 0.93 gram per cc and a pore volume of about 0.1 to about 1 cc per gram with a gaseous chlorosulfonating agent to produce elastomeric, granular, chlorosulfonated polymers having a tensile modulus of less than about 2,000 psi and a crystallinity of less than about 10 percent.

Abstract: Reaction products of a difunctional compound and an organotitanate, process for the preparation thereof and the use of these reaction products as crosslinking agents in the preparation of cured products based on alkylene-alkyl acrylate copolymers. The cured products are especially useful as protective coatings about wires and cables.

The silicone additives have the formula: ##STR1## wherein each R, which can be the same or different, are alkyl radicals, R.sup.1 is a monovalent organic radical containing at least one ethyleneoxide group, vicinal epoxy group or amino group and x and y, which can be the same or different, each have a value of at least one.

Abstract: A valve assembly for dispensing a gas, particularly for medical use into a connector of a gas using device, comprising: an outer body with an internal passageway containing a valve seat and a valve member which is lifted from said seat by rearward pressure, an inner body threaded into the passageway of the outer body and having an internal passage and a plunger within said passage which includes an activating member adopted to hold the valve member away from the valve seat when the plunger is moved rearwardly, the plunger and inner body having interlocking parts by which rotation of the plunger requires rotation of the inner body, said inner body has a stepped profile on the outside for mating with a complementary stepped bore in the outer body and a stepped bore on the inside for mating with a hose connector.
