    摘要： Apparatus for allowing ventilation as usual for underground tunnels through a ventilation shaft opening to atmosphere yet preventing underground flooding from surface waters pouring through the grate, comprises an assembly that fits within the ventilation shaft and includes one or more panels held in an upright home position that allows ventilation as usual but is releasable to rotationally gravitate to a lower sealing position closing a passage between the ventilation shaft and atmosphere to prevent water from entering the underground tunnels. A panel position indicator moves from a hidden position to a visible position with lowering of the panels to visually signify that the panels are lowered and that flooding protection is activated.

    摘要： A rescue signal for use by a person in the water, consists of a tube of thin flexible material, at least about as long as the user's arm and as wide as his hand, inflatable by mouth, of a vivid color such as the international emergency orange. A flag of a similar but contrasting color may be fastened to the distal end. A lanyard for fastening to the user's garment is preferably included. The signal is folded into a compact package and is carried in a downward opening pocket on the user's outer garment, which is preferably a life jacket.

    摘要： A display device including a prism having an object surface, an image surface and a reflecting surface. The reflecting surface is symmetrical in configuration and the object surface is outside the reflecting surface. There is indicia positioned adjacent and outwardly spaced from the object surface such that relative movement between the object surface and indicia along the axis of symmetry of the reflecting surface changes the display visible at the image surface.

    摘要： A rotary display device using a transparent circular prism having a conical reflecting surface, an object surface and an image surface. Indicia is positioned adjacent the object surface and is visible at the image surface at least partially by the use of ambient light from the image surface.

    摘要： A display device using an arcuate-shaped prism having an object surface, an arcuate-reflecting surface and an image surface. There is fixed indicia positioned adjacent the object surface and movable indicator members arranged to move in a path adjacent the object surface such that the display at the image surface will provide useful information in the form of the relationship between the fixed indicia and movable indicator members.
