The process comprises the first step of shearing at least one film selected from the group consisting of a solution, a gel, or a mixture of a solution and gel, of the polymer material between at least one set of two solid surfaces which are in motion relative to one another and which, in a zone in which the shearing takes place, co-extend in closely adjacent face-to-face relationship, at least one of which surfaces is endless, so as to cause by such shearing, solidifi-cation of the polymer material from the solution, or the gel or the mixture of the solution and the gel to a degree sufficient that a coherent, oriented film of the polymer material is formed on one of the surfaces the film being sufficiently coherent to be capable of being removed from the surface on which it is formed.  The second step involves continuously removing the, or each, oriented film of polymer material from the surface on which it is formed.  The oriented polymer film so produced is also novel.

Title: Capillary-pumped heat transfer panel and system
Inventor: EDELSTEIN FRED
IPC: F22B37/10
Filed: 1986-05-13
Granted: 1990-06-12
Abstract: Abstract Of the Disclosure A thermal management system using heat pipe principles and incorporating capillary-pumped equipment mounting panels such that a heat transport loop without moving parts is provided. The panels can function to either absorb heat or to reject heat and can interface with heat generating equipment or heat radiators. Each panel comprises a pair of coextensive flat plates bonded together with a thin, fine-pore sheet wick interposed therebetween. A net-work of liquid grooves in one plate is in fluid communication with the sheet wick which covers the grooves and most of the plate and a separate liquid line connecting the panels. A network of vapor channels in the other plate is in fluid communication with the wick and with a separate vapor line connecting the panels. The vapor channel networks of the panels and the liquid groove networks of the panels are con-nected such that the panels are arranged in parallel in the fluid circuit or loop. A heat input into panels in the loop causes evaporation of liquid off the surface of the sheet wick. Vapor from the evaporated liquid is circulated to panels serving as cold sinks where the vapor is condensed. Capillary action of the wicks returns the condensate to the panels being heated where the cycle is repeated.

Title: Electric arc vapor deposition method and apparatus
Inventor: BERGMAN CLARK
IPC: C23C14/28
Filed: 1986-06-20
Granted: 1992-09-01
Abstract: Abstract An improved method and apparatus for maintaining cathode spots in an electric arc vapor deposition coating process, on the desired cathode evaporation surface are disclosed.   A primary anode is arranged, configured and biased within a vacuum deposition coating chamber relative to a cathodic source so as to maintain an electric arc therebetween.   A relative biasing network maintains a voltage difference during deposition between the primary anode and other conduc-tive surfaces within the chamber, or the chamber wall itself, such that electrons leaving the cathode are preferentially drawn toward  the primary  anode  rather than to other conductive surfaces.  The anode orienta-tion within the chamber causes those electrons drawn toward it to tend to maintain the cathode spots on the desired cathode evaporation surface for maintaining arc stability at low arc current levels.
