Abstract: A flow plate for use as an anode current collector in an electrolytic cell for the production of hydrogen from water is provided. The flow plate comprises a channel plate and a cover plate. A front face of the channel plate is provided with a flow field pattern of open-faced channels defined by depressed portions alternating with elevated portions. The cover plate made of a material that is corrosion resistant in an anodic environment of water electrolysis. The cover plate is arranged parallel on top of the channel plate and in electrical contact with the front face thereof. The cover plate is further provided with a pattern of through-going apertures alternating with closed portions, and the closed portions cover at least the elevated portions of the channel plate.

Abstract: Intercutaneous implant devices useful in intraluminal and extraluminal procedures for externalization of vessels are provided which have a hollow cylinder with an upper and lower end and an interior and exterior surface, said hollow cylinder having a central aperture which is greater in diameter than the exterior expanse of the access site and a length which provides for adequate annular separation of the externalized vessel at the exterior and interior surface of the implant to ensure adequate blood supply to the vessel; a flange extending from the upper end of the hollow cylinder which provides a platform onto which is attached a termination device; and a plane contacting surface extending from the lower end of the hollow cylinder which provides a means for fixation of the implant to the patient.

Abstract: A fiber-reinforced composite material and articles of manufacture formed thereof are formed by the method comprising: forming a compound material comprising a mixture of curable matrix-forming binder, heat resistant reinforcing fibers, and at least one particulate material, wherein the curable matrix-forming binder is 5 to 50% by volume of the compound material; curing the curable binder under simultaneous application of externally applied pressure and ultrasonic energy. Articles according to the invention are useful in a multitude of applications, particularly in applications where the article must retain its shape and properties when subjected to temperatures above the melting point of usual thermoplastic materials, e.g. above 1000.degree. C. The method provides dense, thermally stable, coherent composite materials having a desired high density. Forming and curing times are typically 10 times shorter than conventional methods, e.g. for brake pads in about 3-5 seconds.
