  • Patent number: 7204479
    Abstract: A vibration isolator assembly, such as an isolator bushing or cradle mount, includes a housing and an isolator connected to the housing. A shaft assembly includes first and second mating components, the first component being connected to the elastomer and having a cavity of a first dimension for receiving the second component having a different, second dimension therein. The differing dimensions alters the stress characteristics of the vibration isolator assembly. According to a preferred method of altering stress characteristics of a vibration isolator assembly, the method includes the steps of forming a cavity in the shaft and varying a dimension of the shaft to alter the spring rate characteristics. In the preferred arrangement, the shaft assembly includes a split, first component and a second component is inserted between the split portions to relieve tensile stress in the isolator and, if desired, to impart a compressive stress in the isolator.

In the preferred arrangement, the shaft assembly includes a first component comprising first and second portions, a thin layer of elastomer interposed between the first and second components and a second component which is inserted between the portions to relieve tensile stress in the isolator and, if desired, to impart a compressive stress in the isolator. The thin layer of elastomer permits the first components to be made more economically.

  • Publication number: 20060061023
    Abstract: A vibration isolator is provided that can produce spring rate characteristics of a large preloaded engine bushing mount while also controlling mount excursions similar to those encountered with a smaller engine bushing mount. The isolator assembly improves isolator retention under dislodging forces such as those produced during bumper impact events.

  • Patent number: 6465235
    Abstract: Novel carbonyl hydrolase mutants derived from the amino acid sequence of naturally-occurring or recombinant non-human carbonyl hydrolases and DNA sequences encoding the same. The mutant carbonyl hydrolases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant carbonyl hydrolase to encode the substitution, insertion or deletion of one or more amino acids in the amino acid sequence of a precursor carbonyl hydrolase. Such mutants have one or more properties which are different than the same property of the precursor hydrolase.

  • Patent number: 5939315
    Abstract: Processes for producing various heterologous polypeptides which when expressed are either incorrectly processed and hence asssociated with the surface of the host cell or are not processed to mature form. More specifically, processes for the production of heterologous non-human carbonyl hydrolases expressed either in host cells incapable of producing enzymatically active endoprotease or host cells deficient in enzymatically active extracellular endoprotease are disclosed. Such non-human carbonyl hydrolases generally are incapable of autoproteolytic maturation and become associated with the surface of expression hosts which are deficient in enzymatically active extracellular endoprotease. Processes for preparing non-human carbonyl hydrolase and heterologous polypeptides which are expressed as part of a fusion polypeptide are also disclosed, as well as non-human carbonyl hydrolases which are substantially free of the host cell membrane with which they are normally associated.

  • Patent number: 4086950
    Abstract: A doorway screen has a support extending transversely above a doorway opening. A plurality of individual flexible plastic strips or panels are at their tops secured to and suspended from the support. The strips or panels are formed to have in horizontal cross-section a relatively thin, straight central portion merging at the end edges with relatively thick bulbous or enlarged bead ends. The strips or panels are disposed to overlap each other with each of the end edges of one strip in abutment with the straight portion of an adjacent strip to define discrete pockets between adjacent end edges.
