Abstract: A protective bar for restricting passage through a window type opening in a building structure includes a tubular member adapted to be seated in a recess provided in one side of the window frame with a spring biased slidable bar protruding from the opposite end of the tubular member and adapted to be seated in a recess provided in the opposite window frame member. A malleable material is utilized to form a seat for the spring which biases the rod axially of the tubular member and the malleable material is positively positioned in place by applying axial compression to the material so that it radially expands into a tight frictional relationship with the internal surface of the tubular member. A pull cable release system is also provided which allows the bar to be quickly and easily removed from a location in the interior of the building structure.

Abstract: The quantity of fluid utilized in flushing a conventional closet-type toilet bowl is reduced by a water saving device. The water saving device is adapted to be positioned within the trap of the toilet, and includes a supporting frame with a movable gate operatively connected therewith to open and close the fluid flow passage through the trap to the sewer access opening. After the toilet flushing operation is effected, the gate remains in a closed position until the level of fluid in the toilet bowl reaches a predetermined level, at which time the gate opens to allow the fluid to flow into the sewer access opening by a natural siphoning action. After the flow of fluid through the trap diminishes, the gate returns to a closed position. As a result, the needless flow of fluid from the toilet bowl prior to the time the natural siphoning occurs is eliminated and a water savings is effected.

Abstract: A system for dynamically and automatically balancing vehicle tires includes a plurality of mobile mass elements loosely positioned within the tire of a wheel-tire assembly so as to be mobile therewithin. Inherent physical characteristics of the mass elements in the form of variations in the shape and composition of the mass elements and/or the interior of the wheel-tire assembly inhibit movement of the mass elements after they have been automatically positioned through rotation of the wheel-tire assembly to balance the wheel-tire assembly.
