  • Patent number: 8479611
    Abstract: An improved corkscrew includes a unidirectional clutch mechanism that enables the user to grasp the corkscrew handle, place the screw tip impinging on the cork, and to rotate the handle reciprocally to advance the screw unidirectionally and embed it in the cork. The mechanism features a clutch spring that transfers rotation of the handle to the screw in one direction only, and rotates freely in the opposite direction.
    Type: Grant

    Abstract: An improved corkscrew includes a unidirectional clutch mechanism that enables the user to grasp the corkscrew handle, place the screw tip impinging on the cork, and to rotate the handle reciprocally to advance the screw and embed it in the cork. The mechanism features a clutch spring that transfers rotation of the handle to the screw in one direction only. As a result, fatigue of the user's hand and wrist is substantially reduced, and repetitive stress injuries are diminished.

  • Patent number: 5780237
    Abstract: There is disclosed a diagnostic assay for adult respiratory distress syndrome (ARDS), sepsis, multiple organ dysfunction (MOD) and systemic inflammatory response syndrome (SIRS), comprising (a) measuring the amount of selected unsaturated free fatty acids (FFAs) and saturated FFAs in a body fluid, and (b) determining a ratio value comprising the sum of the unsaturated FFAs divided by the sum of the saturated FFAs. There is further disclosed a diagnostic assay for ARDS, sepsis, MOD and SIRS, comprising (a) measuring the amount of 9- or 13-hydroxyoctadecadienoic acid (HODE) and 5-hydroxy-6-trans-8,11,14-cis-eicosatetraenoic acid (5-HETE) in a body fluid, and (b) determining a ratio value of HETE and HODE.
