  • Patent number: 10654160
    Abstract: A recoil bumper for a nail gun having a body, an axially elongated cylinder disposed within the body of the nail gun, a piston slidably movable in the cylinder, and a driver having a multi-sided cross-sectional configuration, in plan, axially extending along at least a lengthwise portion thereof. The recoil bumper includes a hollow elastomeric member through which the lengthwise portion of the driver endwise passes. The elastomeric member has first and second end faces axially spaced from each other. The first end abuts with the nail gun body while the piston impacts against the second end face during operation of the nail gun. The first end face of said elastomeric member defines a first opening. The second end face of the elastomeric member defines a closed marginal edge for a second opening.

  • Patent number: 8733744
    Abstract: A multipiece cushioning assembly adapted to be arranged in combination with a shock absorbing apparatus. The multipiece cushioning assembly is disposed between a pair of radial shoulders on first and second members telescoping members of the shock absorbing apparatus arranged in operable combination relative to each other. The radial shoulders on the first and second members limit travel of the shock absorbing apparatus, and with the multipiece cushioning assembly including a plurality of elastomeric bumpers arranged in a generally circular array for absorbing over-travel of the first and second members relative to each other and for readily permitting replacement of the multipiece cushioning assembly while maintaining the first and second members in operable combination relative to each other.

  • Publication number: 20100009957
    Abstract: A class of 7-oxo-2,6-diazabicyclo-[3.2.0]-heptane-6-sulfonic acid compounds substituted at the two position of the bicyclic ring with a heterocyclylaminocarbonyl group or a carbocyclylaminocarbonyl group are ?-lactamase inhibitors. The compounds and their prodrugs and pharmaceutically acceptable salts are useful in the treatment of bacterial infections in combination with ?-lactam antibiotics. In particular, the compounds are suitable for use with ?-lactam antibiotics (e.g., imipenem and ceftazidime) against micro-organisms resistant to ?-lactam antibiotics due to the presence of the ?-lactamases.
