Abstract: ABSTRACT           A composite comprises a coating which is ad-hered to a highly saturated elastomer having a corona discharge activated surface which is chemically fixed by a halogenating agent.  A coating such as a paint, a weather-resistant film, etc., or an adhesive layer, is adhered to the activated and fixed surface.  Various halogenating agents include N-halohydantoins, N-halo-imides, N-haloamides, aqueous chlorine or bromine solu-tions, and acidified hypochlorite solutions.  The com-posite is useful for EPDM roofing and consumer goods, e.g., a flexible polyurethane paint applied to the side-walls of tires, as a decorated article, bonded com-posites, and the like.

Filed: 1990-08-03
Abstract: ABSTRACT OF THE DISCLOSURE An adjustable mechanism for supporting an article, particularly for use with an article transportation system, is disclosed.  The support mechanism includes a closed cylinder having a movable piston disposed therein.  The piston divides the interior of the cylinder into upper and lower closed chambers.  A pair of oppositely oriented pressure relief valves are disposed in the piston to selectively permit fluid communication between the upper and lower chambers.  The pressure relief valves open only when the pressure differential exerted thereacross exceeds a predetermined value such that the piston is normally locked in position within the cylinder.  A first rod is connected to the piston and extends upwardly out of the cylinder.  An article engaging platform is secured to the upper end of the upper rod.  A second rod is also connected to the piston, extending downwardly out of the cylinder. The lower rod cooperates with a fixed guide to urge it upwardly or downwardly, as desired to raise or lower the platform relative to the cylinder.  The guide may be adjustably supported to permit easy adjustment of the relative height of the platform.

Title: Isotopically pure single crystal epitaxial diamond films and their preparation
Inventor: BANHOLZER WILLIAM F
IPC: B01J3/06
Filed: 1991-05-09
Abstract: ISOTOPICALLY PURE SINGLE CRYSTAL EPITAXIAL DIAMOND FILMS               AND THEIR PREPARATION                   ABSTRACT OF THE DISCLOSURE The present invention is directed to the production of single-crystal diamond consisting of isotopically pure carbon-12 or carbon-13. The product is believed to be like that diamond product in application Serial No. 448,469, but is made by a different method. In the present invention, isotopically pure single-crystal diamond is grown on a single crystal substrate directly from isotopically pure carbon-12 or carbon-13. One method for forming isotopically pure single-crystal diamond comprises the steps of placing in a reaction chamber a single crystal substrate heated to an elevated CVD diamond-forming temperature. A gaseous mixture of hydrogen and a hydrocarbon of isotopically pure carbon-12 or carbon-13 is provided in the chamber. The gaseous mixture then is at least partially decomposed in the chamber to form an isotopically pure single crystal diamond layer on the single crystal substrate disposed therein. The thus-formed isotopically-pure single crystal diamond layer optionally may be removed from the single crystal substrate. Another method for forming isotopically-pure single-crystal diamond comprises diffusing isotopically-pure carbon-12 or carbon-13 through a metallic catalyst/solvent under high pressure to a region containing a single crystal substrate to form an isotopically-pure single-crystal diamond layer on said single crystal substrate. The single crystal substrate is stable under the high pressure and elevated temperatures used during the diffusion process. The single crystal substrates optionally may be diamond, including the isotopically-pure single-crystal diamond films formed by the inventive method disclosed herein, thus forming multi-layered diamond structures.

Abstract: The invention relates to an iron sponge briquetting press having two opposite rollers. The rollers consist of a roller base body and a coating affixed thereto, in which the moulding recesses for shaping the briquettes are formed. In order to provide less expensive roller coatings as compared with the segments used formerly as coating, which have moreover longer service lives, the invention provides that the coating is produced as a closed ring from a chromium nickel molybdenum steel and is held in press fit on the roller base body. Open grooves are produced in the sleeve surface of the roller base body or on the inner side of the ring as cooling ducts, their open sides being covered by the inner side of the ring or the sleeve surface of the base body in the assembled condition of the rollers.
