  • Modular knee prosthesis system
    Patent number: 5007933
    Abstract: A knee prosthesis system includes a tibial component having a tray element, a femoral component having laterally spaced apart condylar elements, a modular bearing member for being selected and seated within the tray element of the tibial component to provide a bearing support for the condylar elements of the femoral component for operation of the knee prothesis, the bearing member including an eminence projecting superiorly for reception between the condylar elements of the femoral component to provide controlled restraint against excessive relative movement between the femoral component and the tibial component, including control of the anterior-posterior portions of the relative movement, and a stabilizing post within the eminence for reinforcing and stabilizing the eminence against forces exerted upon the eminence during operation of the knee prosthesis.

  • Self-contained portable flood alarm
    Patent number: 4973947
    Abstract: A self-contained, portable flood alarm is installed at a prospective flood site by merely placing the flood alarm on a flood-prone surface at the site and activates an alarm signal in response to the occurrence of a flood condition on the flood-prone surface as a result of the flotation of a buoyant element of the flood alarm, the buoyant element being capable of floating the entire flood alarm so that the alarm signal will commence immediately upon the onset of the flood condition and will continue independent of the height of the crest of the flood condition.

  • Deuterium lamp voltage supply means
    Patent number: 4962335
    Abstract: A deuterium lamp starting circuit utilizing the arc-defining aperture cage of the lamp as the arc-starting electrode to enable the application of a positive, low starting voltage simultaneously with the application of the filament voltage. This positive, low starting voltage is applied to the cage which operates as a starting electrode. After the anode to cathode arc strikes and the anode voltage decreases below the cutoff level, current between the cage and the cathode is reduced and the current flows between the cathode and the anode of the tube.

  • Shade construction
    Patent number: 4934435
    Abstract: A shade construction of the type in which a vertically hanging sheet of shade material is divided by pleats into shade panels, each of which will fold into a forwardly-directed folded configuration upon retraction of the shade, includes a rearwardly-extending loop in the shade material at each pleat, the loop having portions extending in directions parallel to the hanging sheet of shade material so as to assure that the shade material is bent sharply rearwardly at transition portions of the shade material where the panels meet the pleats such that the shade material itself will bias each panel into an aesthetically well-formed forwardly-directed folded configuration.
