  • Patent number: 5097611
    Abstract: An advertising and information display includes a mounting bracket for attaching the display to a conventional retail shelving unit or other structural support, a fixed carrier for holding a relatively small, continuously displayed information medium, and a flexible, user-operable, automatically-retracting carrier for holding a substantially larger, intermittently displayed information medium. The fixed carrier holds a removable user-enticing placard that does not interfere visually or physically with nearby exhibits or products located on that or adjacent shelves. The flexible carrier is preferably a plastic, cloth, or paper sheet which is mounted behind the fixed carrier on a spring-loaded roller or other automatically retracting storage device. A brake preferably controls retraction speed.

  • Patent number: 4520746
    Abstract: An inflated flotation collar is formed around at least part of the hull of a boat by positioning a longitudinal inflatable member along at least part of the length of both the port and starboard sides of the hull. The terminal portions of the member are secured so that the linear length of the gunwale over which the member extends is substantially fixed and so that the member is held substantially at gunwale level on the hull by securing devices passing around and optionally over but not under the hull. The inflatable member is inflated, whereby the expansion of the member causes the member to bear against the hull against the restraining effect of the securing of the terminal portions.
