  • Patent number: 5682383
    Abstract: An arrangement for interconnecting groups of users into collision domains in a Local Area Network such as an Ethernet comprises a plurality of repeater groups, with each repeater group being connected to a group of user stations. The arrangement also comprises an electronically reconfigurable switch matrix. The switch matrix comprises a plurality of segment lines (or other transmission media) each of which is used to form one collision domain or Ethernet segment. Switch elements under the control of a microcontroller selectively connect particular repeater groups (and the associated user groups) to particular segment lines to form Ethernet segments, each Ethernet segment being a single collision domain. Internetworking devices such as bridges and routers may also be connected to the switch matrix to interconnect particular collision domains.

  • Patent number: 5415836
    Abstract: An antifouling structure in contact with seawater or at least its surface layer is made up of a beryllium copper alloy having a beryllium content lying in the range of 0.2% by weight to 2.8% by weight. While this antifouling structure is immersed in seawater, a beryllium or copper oxide film is formed on the surface layer of the beryllium copper alloy mother material and beryllium or copper ions are liberated from the exposed surface layer of the beryllium copper alloy mother material into seawater. As years go by, the beryllium or copper oxide film peels away from the beryllium copper alloy mother material. Due to indeterminate repetition of such peeling, the liberation of beryllium or copper ions from the exposed surface layer of the beryllium copper alloy mother material into seawater is sustained.

  • Patent number: 5135582
    Abstract: The present invention is directed to a method for producing a diaphragm for highly brittle metals used in loudspeakers, comprising a step of making a laminated plate by stacking a plate of superplastic material on a plate of highly brittle metal. The laminated plate is arranged on a mould, and the laminated plate is heated to a predetermined range of temperatures, determined according to the highly brittle metal. Subsequently, the laminated plate is deformed by pressuring the laminated plate in the mould, at the range of temperatures. Thus, a diaphragm can be formed from a plate of highly brittle metals, without causing brittle fracture or generating internal or surface defects.

  • Patent number: 4923509
    Abstract: A powdered material and a process for producing the material are disclosed. The powdered material consists essentially of light metal based spherical particles which are essentially free of elliptical shaped material and elongated particles having rounded ends. The process for making the spherical particles involves mechanically reducing the size of a starting material to produce a finer powder which is then entrained in a carrier gas and passed through a high temperature zone above the melting point of the finer powder to melt at least about 50% by weight of the powder and form spherical particles of the melted portion. The powder is directly solidified.

    Abstract: Alloys of beryllium with Group IV or V metals of C22 Aluminum Boride, C15 Laves or C14 Laves phase structures and an atom ratio of 2:1 form hydrides reversibly. Either beryllium or the Group IV or V metal or both are in some instances substituted for in part by selected metals up to the solubility limit in the phase structures. Exemplary systems are based on Be.sub.2 Ti with substitutions made to increase the stability of the hydride, or are based on Be.sub.2 Zr with substitutions made to decrease the stability of the hydride.
