  • Patent number: 5445182
    Abstract: A mechanical control valve that can automatically direct the flow of fluid between two output lines. The control valve has a housing with a fluid inlet, a first outlet and second outlet. The valve also has a poppet that allows fluid to flow out of the first outlet when in a first position and through the second outlet when in a second position. The poppet is normally in contact with a mechanical timing switch. When fluid initially flows into the housing inlet, the poppet directs the fluid to the first outlet. The fluid activates the mechanical timing switch which releases from the poppet. When the fluid no longer flows through the valve, a spring moves the poppet into the second position. At the same time, the mechanical timing switch begins to move back into contact with the popper. An orifice controls the movement of the switch, so that there is a time delay between the moment the fluid pressure in the valve drop, to the point when the poppet is pushed back to the first position.

  • Patent number: 5395012
    Abstract: A attachment that can be attached to the opening of a container to pressurize the same with a gas. The attachment has a housing which holds a removable cartridge that contains either pressurized nitrogen or CO.sub.2. Extending from the attachment is a button that is connected to a valve which controls the flow of gas into the container. The button and valve are coupled to a spring which functions as a regulator that controls the gas pressure within the container. When the button is depressed, the valve is opened and the gas is allowed to flow into the container. The spring maintains the valve in the open position until the gas pressure overcomes the spring force and closes the valve. Varying the movement of the button varies the spring force and the gas pressure within the container.

  • Patent number: 5304971
    Abstract: A high speed solenoid valve that has a housing with an inlet and outlet that are typically connected to a pneumatic system to control the flow of air across the valve. The solenoid has a first magnetic core coaxial with an armature. Wrapped around the first core is a coil that is connected to a source of power. The coil emits a magnetic flux when current flows through the coil. Adjacent to the coil is a second magnetic core that is attached at one end to the first core and spaced from the opposite end of the first core by a first bushing. Attached to the armature is a magnetic plate that is adjacent to the spaced apart ends of the first and second cores. When the coil is energized, the magnetic flux flows through the magnetic cores and plate, pulling the plate toward the cores and moving the armature from a first to a second position.

  • Patent number: 5251659
    Abstract: A solenoid valve which has a first magnetic core that is separated from a second magnetic core by a bushing. The bushing has an inner corner that sits within an outer seat of the first magnetic core, and an outer seat that cooperates with an inner seat of the second magnetic core such that the magnetic cores capture the bushing.

  • Patent number: 5022565
    Abstract: A portable dispenser for fastening to a conventional carbonated beverage container and providing the convenient dispensing of the contents therein while maintaining the carbonation of the beverage until fully consumed is disclosed. The dispenser is comprised of a body assembly for threadedly engaging a conventional carbonated beverage container, such as one liter, two liter and three liter PET containers, and sealing with respect thereto. The body assembly contains a tube assembly for extending from the bottom of the beverage within the container to the dispenser outlet, with a valve mechanism spring loaded to squeeze the tube closed and manually operable for controllably allowing the flow of the beverage therethrough. The body assembly includes a unique pressure regulator and a CO.sub.2 cartridge in a cartridge holder for providing a source of CO.sub.2 at the regulated pressure to the beverage container.

  • Patent number: 4811221
    Abstract: Simplified battery operated automatic and manually operable valves for use in sprinkler systems and the like are disclosed. The valves are operable from a latching actuator controlled through a microcomputer programmed to turn the valve on and off at a specific time of the day. For purposes of programming the system once batteries are in place, the user simply pushes an on/off button at the desired turn on time of the day, at which time the valve will turn on. At the same time, the time of the turn on occurrence will be retained in memory. Similarly a subsequent operation of the same switch will turn off the valve and cause the storage in memory of the corresponding turn off time. Thereafter, the valve will automatically turn on and turn off at those programmed times on each subsequent day, or on such days as are commanded by control of a manually operated switch or as permanently wired.

  • Patent number: 4760681
    Abstract: A deformable molding is provided to form watertight sealing between formica covered panel members such as back-splash boards and countertops. The molding includes a first part to fit between first and second panel members and to be secured thereto by pressure-sensitive adhesive means. The molding also includes a pair of lip portions adapted to be biased into pressure sealing contact with respective adjacent panel members.
