  • Patent number: 10302382
    Abstract: A system and method for quickly and safely inserting multiple rounds of ammunition into a magazine. The system is adjustable for various sizes of magazines and calibers of cartridges. Users depress a plunger that applies a force to the exposed cartridge in the magazine thereby compressing the spring inside the magazine and providing room for another round to be inserted into the magazine. The plunger is then released and the process can be repeated until the magazine is filled or the user is done.

  • Patent number: 10131560
    Abstract: A system and method includes an aeration subsystem that excites enzymes in the liquid waste passing through the septic system along with a bypass system that directs liquid waste during power outages. The bypass system utilizes a mechanically activated bypass valve moved by a float. The aeration subsystem includes a compressor section that compresses the liquid waste. The method includes mixing enzymes into the fluid waste material, compressing the fluid waste material with the compressor, injecting air into the compressed fluid waste material, and determining whether the fluid waste material is at a desired cleanliness, and if not, recirculating the fluid waste material through the compressor.

  • Publication number: 20010008319
    Abstract: A prefabricated insulated wall panel for building a wall. The wall panel includes one or more outer planar portions, a plurality of rib portions integral therewith and normal thereto and between which insulation is received, a strip of insulation attached to the inner edge of each rib portion for reducing thermal conductivity from the respective rib portion to wallboard attached to the wall panel, and a wallboard nailer strip which extends about the sides of the strip of insulation and has edge portions which are anchored in the respective rib portion. In accordance with one aspect of the invention, the nailer edge portions are insulated from the respective rib portion to limit thermal conductivity from the respective rib portion to the nailer. In accordance with another aspect of the invention, a pair of planar portions extend at an angle relative to each other so that the panel serves as a corner wall panel.

  • Patent number: 5137368
    Abstract: A viscous fluid pumping system having a pair of opposing gears (130, 132) is provided in a housing (32) disposed above an inlet port (73) in a follower plate (70). The follower plate (70) is dimensioned to sealingly fit in a container or drum (D) filled with highly-viscous fluid. In operation, the gears generate a vacuum between the follower plate (70) and the viscous fluid, allowing atmospheric pressure to press the follower plate into the viscous fluid. This, in turn, forces the fluid through the inlet port (73) and into the gears (130, 132). The gears exert high shear forces and localized heating to the fluid, decreasing its viscosity. The fluid exits the system through an outlet in the gear housing. The pumping system may use two such pumps working in conjunction or incorporate a single such pump with a valve structure for recycling fluid through itself.

  • Patent number: 5005982
    Abstract: A material processor for processing materials to improve their rheological and material properties includes a housing defining a process chamber and having an inlet for introducing materials therein and an outlet for discharging materials therefrom. Intermeshing gears are rotatably positioned in the process chamber and define an area of intermesh which is positioned in the flow path between the inlet and the outlet of the process chamber. A power source is provided for rotating one or both of the intermeshing gears. The mesh between the gears is such that during rotation, a clearance exists therebetween permitting a path between the gears such that material may flow from the discharge side to the inlet side of the gears through the intermesh and be subjected to extreme pressures, localized heating, shear and cavitation effects resulting in the processing of the materials.

  • Patent number: 5005765
    Abstract: A method and apparatus for metering and pumping multicomponents of high and low viscosity materials and subsequently mixing and applying the mixture includes gear pumps for pumping each component. Each gear pump has gears operating in a gear housing for receiving and pumping one of the components. The gear pumps are simultaneously driven at a predetermined speed and each gear pump is designed to pump a predetermined amount of its respective components, at the predetermined speed. Flexible hoses connect the pumps to an applicator. Check valves are used to maintain the pressure in these hoses when the pumps are in their at-rest position. The gear pumps may be driven at the same rotational speed but are designed to pump a predetermined amount of the different materials so that the ratio of materials can be precisely set.

  • Patent number: 5004159
    Abstract: A method and apparatus for metering and pumping a single fluid of any viscosity includes a gear pump for pumping the fluid, the pump having a discharge connected by a hose to a dispenser. A check valve is used to maintain the pressure in the hose when the pump is in its at-rest position. The gear pump need only be operated as necessary to maintain pressure in the hose. Precise metering of the fluid pumped is accomplished by controlling the operation of the gear pump.
