Abstract: A method and apparatus for forming a shape such as a cavity in a workpiece. An aperture is provided in the area in which the cavity is to be formed. Thereafter, the cavity is depressed into the metal causing the metal to flow into the area from which metal was removed by the aperture formation. If desired, after formation of the original aperture, the cavity may be partially depressed, and the aperture requalified to a circular shape. Thereafter, the cavity may be depressed into the workpiece to its final depth.

Abstract: The present invention relates to a hydraulic fluid composition comprising: (a) a base fluid and (b) as an anti-mist additive, an alkylene-vinyl ester copolymer having a molecular weight of between about 5,000 and about 100,000 and soluble in said base fluid. In another aspect, the present invention relates to a process for imparting flame retardancy and reduced wear characteristics to a hydraulic system which comprises adding to the hydraulic system the above-identified hydraulic fluid composition.

Abstract: A cable tensioning system for use in an electrostatic transfer apparatus is provided to permit a developed image to be transferred from a first surface to a second receiving surface so that the dimensional integrity of the transferred image is ensured. The cable tensioning system is connected to a web or belt material that receives the transferred image as an intermediate transfer surface by a transfer roller traversing the length of the web bringing one surface of the web into close proximity with the developed image to permit it to be transferred to the web. The tensioning system prevents the web from becoming slack.

Abstract: Described herein is a process for the direct oxidation of propylene to propylene oxide in conditions such that propylene is above its critical temperature and pressure.

Abstract: An ammunition cartridge is disclosed comprising a projectile threadably attached to a combustible case body via a threaded combustible case adapter. At least one of the adapter end have an uniform density of polyurethane resin to provide strength and sufficient support for the threads. The combustible case body may also have an uniform resin density to support threads corresponding to those on the rear end of the adapter. The preferable uniform polyurethane density is about 0.75 grams per cubic centimeter.

Abstract: Described herein is an improved process for electroplating a conductive metal layer to the surface of a nonconductive material comprising pretreating the material with a carbon black dispersion followed by a graphite dispersion before the electroplating step.

Abstract: There has been provided an electrical component having resistance to oxidation and wear. The component has a copper or copper alloy substrate coated with a relatively thick layer of silver. A thin layer of gold may be deposited on the external surface of the silver coating layer to improve oxidation resistance, lubricity and to serve as a diffusion barrier.
