  • Patent number: 11841048
    Abstract: The present invention is directed at products and methods related to the manufacture of a bearing with a bearing liner and the bearing liner on its own. The bearing liner within the bearing includes a fabric with a bonding side polymerized resin composition dispensed on one side and a sliding side polymerized resin composition disposed on a second side that contains dispersed lubricant. The liner preparation also offers the ability for the liner to conform to a selected bearing surface.

  • Patent number: 9951820
    Abstract: A bearing with a wear surface sensor configured to wirelessly transmit information comprising a bearing wear surface containing a wear surface sensor wherein the wear surface sensor includes one or more connecting wires for transmitting a data signal from the wear surface sensor indicative of the state of wear of the bearing wear surface. The one or more connecting wires extend outside of the bearing wear surface and are connected to a radio frequency communicator for transmitting a data signal from the sensor indicative of the state of wear of the bearing wear surface. The radio frequency communicator and the sensor are fixed relative to one another such that the connecting wires are not flexed to failure during bearing use.

  • Patent number: 7115037
    Abstract: Universal joints, and more particularly, an apparatus and method for servicing staked universal joints as well as a u-joint serviced with the method and the apparatus. The service kit includes a replacement bearing assembly, a retention assembly and a spacer sized to fit between the retention assembly and the replacement bearing assembly. The method generally includes the steps of removing the stakes from an aperture on a driveshaft, removing an original bearing assembly from the aperture, inserting the replacement bearing assembly into the aperture, inserting the spacer into the aperture and retaining the spacer and replacement bearing assembly within the aperture with the retention assembly.

  • Patent number: 6790646
    Abstract: A highly conserved active site helix present within the P-450 superfamily of proteins is found also in monoamine oxidase (MAO) B, a major enzyme that catalyzes deamination of neuro- and vaso-active amines in the nervous system of mammals. Mutation within the conserved region of the MAO B enzyme directly reduces MAO B's activity and alters its pH profile, which allows for indirect regulation of the cellular neurotransmitters and vasoamines.

  • Patent number: 5863776
    Abstract: The present invention provides a method of preparing apoenzyme of a riboflavin-dependent enzyme, comprising the steps of: growing COS-7 cells in a riboflavin-free medium; introducing a cDNA encoding a riboflavin-dependent enzyme; and expressing said cDNA. Also provided is a method of screening for an inhibitor of a flavin dependent enzyme, comprising the steps of;contracting a potential inhibitor of a flavin dependent enzyme with the cell line of claim 7 in the presence of riboflavin, FMN or Fad; and measuring the enzymatic activity of the flavin dependent enzyme.

  • Patent number: 5756479
    Abstract: The present invention provides an inhibitor of monoamine oxidase comprising a modified synthetic flavin adenine dinucleotide compound. Also provided is a method of inhibiting monoamine oxidase enzymatic activity in a cell, comprising the step of contacting said cell with a pharmacologically effective dose of a modified synthetic flavin adenine dinucleotide compound. Further provided is a method of treating a brain pathophysiological state in an individual, comprising administering a therapeutically effective dose of a modified synthetic flavin adenine dinucleotide compound to said individual.
