  • Patent number: 5454127
    Abstract: An unbalanced bascule bridge having an unbalanced bridge span including a pair of longitudinal girders with a low torsional stiffness interconnected at a pivoting end by a torsionally rigid cross-girder and interconnected along a longitudinal expanse of the longitudinal girders by a steel frame which forms a closely spaced lattice for supporting a relatively thin, lightweight concrete roadway deck. The bascule bridge span is raised and lowered by an actuator assembly including a plurality of hydraulic cylinders pivotally mounted on support columns and corresponding piston rods which apply a torque to the cross-girder through crank-plates welded to the cross-girder and pivotally interconnected to a base. The cross-girder isolates the longitudinal girders from all support and reaction forces while raising and lowering the bascule bridge span.

  • Patent number: 5439724
    Abstract: A lid for sealing a container. The lid adheres to the container by a vacuum formed within the container. The lid is formed of a substantially circular panel having a flanged perimeter and a concave depression on an upper side of the circular panel. A pressure release hole extends through the concave depression of the circular panel and sanitary coating is disposed on a lower side of the circular panel. A first adhesive material is applied to the lower side of the lid by fusion to the sanitary coating to form a thin film over the release hole, and a second adhesive material is disposed in the concave depression on the upper side of the lid to form a removable seal. The second adhesive material has the same properties as the first adhesive material.

  • Patent number: 5439853
    Abstract: In order to provide a mixed oxide ceramic sintered body having no defect such as void and pore, and high strength, toughness and reliability, a mixed oxide of rare earth oxide-alumina oxide added with silica is fired with a non-oxide mixture of SiC and/or Si.sub.3 N.sub.4. In the production method, the crystal grain size of the sintered body is controlled to not more than 30 .mu.m, and abnormal grain growth and occurrence of pore can be restrained to easily produce a practically usable mixed oxide ceramic sintered body having excellent toughness inherent to oxide sintered body and excellent high-temperature strength inherent to SiC and Si.sub.3 N.sub.4 and uniform structure.

  • Patent number: 5438667
    Abstract: A method of bidirectional data transmission between a computer system comprising at least two computers and at least one peripheral unit e.g. a magnetic tape terminal via data paths. The computers have different control unit address administration using addressing logs. Each of the peripheral units has a unique control unit address and is connectable via normal data path to that computer which has a consistent control unit address. The procedure provides detecting the addressing logs on the data paths, whereby an addressing compatibility device is switched into the data path of a computer having a control unit address which is not identical (inconsistent) to the control unit address of the peripheral unit. An addressing generator is set to the designated control unit addresses.

  • Patent number: 5432989
    Abstract: An apparatus for joining a plurality of metal sheets by first drawing and then laterally extruding the metal into an enlarged shape which will permanently and mechanically interlock the two metal sheets. The apparatus utilizes a novel die body construction in which the die body has a cavity wall provided with a plurality of longitudinally extending flutes which communicate with a depressed groove surrounding a centrally raised portion of an anvil. Upon compression and drawing, the material from the metal sheets will extrude from the raised central portion of the anvil into the depressed groove and the extrude laterally into the substantially longitudinally extending flutes which allow the finished assembly to be withdrawn from the die body along the path of the substantially longitudinally extending flutes. A method of forming a joint between metal sheets is also disclosed. Also disclosed is a die body which permits withdrawal of the finished product without requiring movable releasable portions in the die.
