Abstract: A polymer blend comprises a high nitrile polymer and a compatible polyolefin functionalized with an unsaturated compound selected from the group consisting of unsaturated carboxylic acids, esters, anhydrides and imides. Such blends can be used to form films and membranes having improved thermal, mechanical and optical properties.

Abstract: Strip steel is continuously cast by immersing a mold into a melt of liquid steel, solidifying liquid steel on a starter bar disposed within the mold, and oscillating the mold as the starter bar is withdrawn upwardly from the mold. The mold includes, at its lower end, an insulating ceramic entry die. The remainder of the interior surface of the mold is defined by a water cooled copper or copper alloy liner. The mold can be vertical or it can be inclined at an angle to the horizontal in order to facilitate feeding strip steel directly into a rolling mill or hot coiler. Alternatively, the interior of the mold can be curved so that strip steel issuing from the mold is directed horizontally into the rolling mill or hot coiler.

Abstract: A method of electrodepositing a doped compound semiconductor film including tellurium and a metal selected from Group IIB of the Period Table of Elements by adding an effective concentration of dopant ions to the electrolyte bath. Cadmium telluride, mercury cadmium telluride and zinc cadmium telluride may be doped with copper, silver and gold. The conductivity type of the electrodeposited doped layers may be changed by a heat treatment. Thin film photovoltaic cells incorporating the doped layer to form a heterojunction with a semiconductor layer of the opposite conductivity type show substantial improvements in open circuit voltage, fill factor and efficiency over similar devices employing undoped electrodeposited layers.
