  • Patent number: 9132575
    Abstract: A method of making a carburetor float by first creating a homogeneous mixture of gas and polymer in a plastic injection machine. The gas/polymer mixture is injected into a tool having a mold cavity. A moveable portion of the mold cavity allows the gas/polymer mixture to expand in that area thus forming a foamed portion of the finished float. The portion of the mold that is stationary does not allow the gas/polymer mixture to foam and thus forms a portion of the finished float with a higher density that the foamed portion. The result is a float made of the homogeneous mixture with two differing densities in two different portion of the float.

  • Patent number: 8584909
    Abstract: A dispensing tap for beverages that comprises an actuator and a valve housing. A conical spring washer is joined and/or sealed to an actuator base to form the actuator. The actuator is then inserted into the valve housing to form the dispensing tap for attachment to a container containing a liquid. In use, a force is exerted on the conical spring washer to actuate the actuator base within the valve housing and thereby create an opening and/or passageway in the dispensing tap. Once opened and as the force is maintained, the liquid in the container can flow through the opening or passageway for dispensing the liquid out the dispensing tap. Upon releasing the force, the conical spring washer returns back to its original position. This movement of the conical spring washer causes the actuator base to move in the reverse direction within the valve housing thereby closing the opening and/or eliminating the passageway in the dispensing tap.

  • Publication number: 20120111901
    Abstract: A drip resistant dispensing valve for fluids is disclosed, which provides a dispensing outlet configured to minimize the tendency for residual fluid to collect in and drip from the dispensing outlet while maintaining a simple construction for ease of manufacture. The dispensing outlet face is situated a distance away from the valve body, which tends to prevent, or at least minimize the risk of, contact between potentially contaminating external surfaces with the surfaces of the discharge outlet. Such construction assists in minimizing the retention of fluid on the surfaces of the dispensing outlet, and migration of the fluid to surfaces outside of the dispensing outlet that could tend to promote growth of biological contaminates and/or provide additional surfaces that could pool fluid following a dispensing operation and thereafter drip from the valve.
