Abstract: Described is a plastic bottle fitted with a one-way check valve and an inner bladder containing a substance such as mustard or ketchup. When squeezed, the substance is dispensed from an inner bladder through an aperture in the top. When released, air is allowed into the bottle through the valve to displace the substance dispensed. Since the valve will not allow air out of the bottle, the bladder continuously shrinks until all the substance is dispensed without any waste or the need to strike the bottle or store it upside down. No air comes into contact with the substance thus avoiding bacterial contamination.

Abstract: An improved pushbutton quick-release socket wrench includes an adaptor which comprises a hollow elongated member having a spring-loaded elongated member mounted axially within a central recess. A ball extends through the side wall of the member at one end of the member to engage a bearing recess in a socket which mounts to one end of the adaptor. A cam portion of the spring-loaded elongated member permits coupling of the ball to the mating socket when a plunger button on the wrench is depressed. Releasing the button drives the ball into contact with the socket recess to provide an integral structure for operating purposes. The adaptor is coupled to the driving stud of the wrench by driving a protruding ball into contact with a mating hole on the other end of the adaptor. The ratchet structure with a hollow stud extending therefrom with an axial plunger is mounted within a toothed recess in the wrench handle.

Abstract: The circuit of this invention provides a safety belt system for both shoulder and seat belts which require the driver and any passengers to positively fasten the seat and shoulder harness in a sequential manner in order for the automobile to be started. After the engine is started, disconnection of any belt or harness causes a buzzer or like alarm to be actuated. The circuit is shown as being operable with either of two relay systems. One system uses a latching relay the other uses a stepping relay.
