  • Dark coating with low solar infrared absorbing properties
    Patent number: 5749959
    Abstract: A stable dark or moderately dark opaque exterior coating constituted of pentations and binder materials having low solar absorbing properties capable of visual and infrared camouflage. The pigmentations and binder materials may be selected for the proper optical qualities by previous testing before mixture and application as a coating.

  • Convectively cooled hot gas exhaust structure to reduce infrared radiation
    Patent number: 4993314
    Abstract: The invention is a new design for a structure such as a stack for exhaust hot gases. One embodiment is that of the top portion of a ship's stack (the watchcap) for exhausting a hot steam plant, a gas turbine, a diesel or other engine, or burner exhaust gases. The function of the invention is to reduce the infrared radiation generated by the hot metal of the exhaust pipe and surrounding structure. This function is accomplished by constructing an annular plenum chamber around a portion of the length of the smokepipe. The plenum chamber has air flow channels, an arrangement of insulation, and openings, top and bottom, so that convective air flow is established at the hot smokepipe wall. The thermal gradient produced also induces a secondary cool-air-flow along an outer wall. Another feature is an arrangement of a double-walled shield extending above, below, and around the terminal end of the smokepipe that blocks the low angle view into the hot smokepipe.

  • Surgical holder for a laparoscope or the like
    Patent number: 4573452
    Abstract: Mechanical components for holding and positioning a laparoscope incident to its use during surgery, wherein a selectively tensionable cable-type component is released for moving the laparoscope almost into its desired position and then tensioned into a rigid structure, and then a ball and socket joint is rendered operational to complete the moving of the laparoscope, if need be, to precisely position this instrument in its required anatomy-viewing position.
