Patent number: 4786844Abstract: An ion plasma electron gun for the generation of electron beams which exhibits electron beam dose uniformity and which is capable of varying the dose received by a material to be irradiated. Positive ions generated by a wire in a plasma discharge chamber are accelerated through an extraction grid onto a second chamber containing a high voltage cold cathode. These positive ions bombard a surface of the cathode, causing the cathode to emit secondary electrons which form an electron beam. After passing through the extraction grid in the plasma discharge chamber, the electron beam exits from the gun by way of a second grid and a foil window supported on the second grid. The gun is constructed so that the electron beam passing through the foil window has a relatively large area and uniform electron distribution which is subsantially the same as the ion distribution of the ion beam impinging upon the cathode.Type: GrantFiled: March 30, 1987Date of Patent: November 22, 1988Assignee: RPC IndustriesInventors: Sherman R.

Patent number: 4771818Abstract: A process for shaping a metal alloy in which a semi-solid metal alloy charge is shaped under pressure in a closed die cavity. The metal alloy is vigorously agitated, while in the form of a liquid-solid mixture, to convert from 30% to 55% by volume to discrete degenerate dendritic solid particles. The liquid-solid mixture is then cooled to solidify the mixture and reheated to form a semi-solid slurry. The reheated metal alloy slurry contains discrete degenerate dendritic primary solid particles, in a concentration from about 70 to 90% by volume based upon the volume of the alloy, suspended homogeneously in a secondary liquid phase. The process is characterized by low pressure and very rapid shaping and solidification times. The process produces complex, close tolerance, high quality metal alloy parts.Type: GrantFiled: August 5, 1981Date of Patent: September 20, 1988Assignee: Alumax Inc.Inventor: Malachi P. Kenney
