Abstract: A toilet odor ventilating assembly (TOVA) (10) that is designed to be produced either as a kit for modifying a standard toilet assembly or to be integrated on to an original equipment manufacture (OEM) toilet assembly. When produced as a kit, the TOVA (10) can be easily installed onto a standard toilet assembly (160). The TOVA (10) kit is comprised of three major elements: a lower air-flow conduit (12), an upper air-flow conduit (56), and an electrical activation unit (120). The three elements function in combination to effectively eliminate or substantially reduce toilet odors emanating from the toilet bowl (168). The OEM design of the TOVA 10 requires that the toilet bowl (168) include an air inlet opening (200) that has attached an air inlet flange (204) and an air outlet opening (202) that has attached an air outlet flange (214). Between the two flanges is attached a flexible air hose (130) that passes the air flowing from the toilet bowl (168) into the sewer.

Abstract: A fire-extinguishing device (10) that is disclosed in three embodiments. All three embodiments utilize a water-spraying unit (12), a water hose (20) and a water-delivering tube (28). When the device (10) is attached to a pressurized water source (150) a water spray can be directed into a burning area. The first embodiment of the device (10) utilize a triangular water-delivering tube (28) that when attached to an elongated water supply tube (64) functions as a battering ram for penetrating a building structure. The second embodiment consists of an elongated water-delivering tube (28) having a lower section (36) that has attached a support structure (94) that is angled to substantially fit over a gabled roof. The third embodiment is also comprised of an elongated water-delivering tube (28) that is attached to a side of a fire truck (160). When the truck (160) is parked alongside a burning structure a water spray is produced that is directed into a burning area.

Abstract: An improved wheelchair for mechanically assisting in moving a disable person between a sitting and a standing position. A method and apparatus for automatically coordinating the movements of the feet, lower-leg, thigh, seat and back, including the initial pivotal raising of the lower-leg and foot followed by a reversal of direction as the upper-leg and back commence pivotal movement to achieve preliminary alignment of the leg prior to achieving complete upright alignment of the entire body. A lever mechanism having a forward lever arm coupled to a lower-leg support through a cam, and a rearward lever arm coupled to a seat and/or back through a delayed-action channel member.
