摘要:
All improvement in a kit for converting a motorcycle to a tricycle is described. The kit includes a pair of swing arms having a first end and a second end. Axle couplings are provided at the first end of each swing arm whereby the swing arms are secured to an axle which supports two wheels. Pin receiving couplings are provided at the second end of each swing arm whereby the swing arms are pivotally secured by pins to a motorcycle frame. The improvement is characterized by swing arms having a top surface and a bottom surface. The axle coupling and the pin receiving coupling extend vertically from the top surface of the swing arms. The top positioning of the axle couplings and the pin receiving couplings leaves the majority of the top surface of the swing arms dropped below the level of the original floor boards of the motorcycle. The swing arms can pivot as intended without their movement being impeded by the original floor boards.
摘要:
An optical interconnection system, particularly useful in a backplane arrangement in an electronic assembly. The interconnection system includes “dual-use” protective covers for protection from damage and/or cleaning within backplane and daughter card style connectors. The protective covers are modular for easy use. Some versions contain adhesive members that can remove contaminates from various portions of the connector assembly. The protective covers can be inserted into a backplane connector of an electronic assembly using a tool or as part of a “dummy board.”
摘要:
An optical connector system joining waveguides in two printed circuit boards. A flexible optical conductor is connected at one end to one of the boards. The flexible conductor includes at its free end an alignment structure that provides a separable, low loss interface to an alignment structure coupled to the waveguide on the other board. The ends of the waveguides are enclosed in housings that protect the waveguides from abrasion and contaminates, but expose the waveguides when the connectors mate.
摘要:
An optical connector system assembled from modular components. These components include connector modules that position ferrules for mating and providing fine alignment to fibers. The modules are assembled to support members to form connectors of various sizes. Mounting modules are attached to the support members. Various shaped mounting modules are provided, allowing connectors to be assembled for various configurations, such as a matrix configuration, a parallel board-to-board configuration or a panel mount configuration.

The invention encompasses a method and apparatus for producing high-purity metals (such as, for example, high-purity cobalt), and also encompasses the high-purity metals so produced. The method can comprise a combination of electrolysis and ion exchange followed by melting to produce cobalt of a desired purity. The method can result in the production of high-purity cobalt comprising total metallic impurities of less than 50 ppm. Individual elemental impurities of the produced cobalt can be follows: Na and K less than 0.5 ppm each, Fe less than 10 ppm, Ni less than 5 ppm, Cr less than 1 ppm, Ti less than 3 ppm and O less than 450 ppm.
