Abstract: An improved animal feed dispenser is provided having a slow speed paddle wheel and a high speed distributor wheel. The high speed distributor wheel transports feed out of an opening in the device to spread it on the ground. The slow speed paddle wheel moves feed at a measured rate from a storage hopper and feeds it to the distributor wheel. A detachable mounting plate is used to attach the dispenser to a storage hopper, and is releasable therefrom without emptying the hopper of feed. The slow speed paddle wheel is formed from a material flexible enough to prevent feed jams caused by water absorption of the feed and other events.

Abstract: A downhole pumping assembly has a tubing string with plural barrels which are arranged in-line with the tubing. The tubing string has a seating location adjacent to each barrel. A standing valve arrangement, which includes a standing valve and a seating device, is located with the standing valve adjacent to the lower end of one of the barrels. A plunger has a traveling valve that is located for reciprocation within the one barrel. The plunger has a clearance with each of the barrels so as to form a fluid seal. The plunger reciprocates inside the barrel so as to lift fluid to the surface. Over time, the barrel will exhibit wear. Instead of pulling the entire tubing string to replace the barrel, the standing valve and the plunger are relocated to one of the other barrels located in the tubing string and reciprocation is resumed to resume pumping.

Abstract: Mixed alcohol formulas can be used as a fuel additive in petroleum, synthetic or bio-derived gasoline, diesel fuels, jet fuel, aviation gasoline, heating oil, bunker oil, coal, petroleum coke or as a neat fuel in and of itself. The mixed alcohol formulations can also be utilized as a thinning agent to improve the transportation of heavy petroleum crude oils or bitumen produced from tar sands. The mixed alcohol formulations can contain combinations of two or more, three or more alcohols, or blend of C1-C5 alcohols, or C1-C8 alcohols or higher C1-C10 alcohols in order to boost energy content. The primary benefits of mixed alcohols are increased combustion efficiencies, improved fuel economies, reduced emissions profiles and low production costs. These improved combustion efficiencies result in increased miles per gallon of blended fuel.

Abstract: An inexpensive and disposable dispenser has few parts. The dispenser has a housing with a reservoir of fluid therein. The housing has a valve seat and a valve. The valve is biased in a closed position by resilient spring arms. Each spring arm has a fixed end coupled to the housing and a free end that contacts a rounded or inclined surface of the valve in a location that is offset from a centerline of movement. As the valve moves to an open position, the spring arms flex with the free ends moving apart. When the spring arms straighten and the free ends move closer to each other, the valve is moved to the closed position. The dispenser can be manipulated by a hand or by a massager. A massager imparts vibrations to the valve by way of the housing and the spring arm. The dispenser can be used to work the fluid into an object such as human skin.

Abstract: A wheel is for use in manually turning a shaft on rolling stock, such as for a handbrake. The wheel has a hub and a rim. The hub is made of a first material and has an opening that is structured and arranged to receive the shaft. The opening has a rotational axis. The hub has an exterior around the rotational axis, with the hub having drive surfaces relative to the rotational axis. The rim is coupled to the hub so as to engage the drive surfaces. The drive surfaces include flat surfaces and corners of a tube portion of the hub, a radially extending plate with holes therethrough and teeth in an outer edge and gussets coupled between the tube portion and the plate. The rim has an outer periphery structured and arranged to be gripped by a human hand for rotating the wheel. The rim is made of a second material that is softer than the first material.

Abstract: A stress and torque reducing tool has a plunger that reciprocates inside of a body. The tool is connected between the pump and the sucker rod string and reduces stress transmitted therebetween. The body and plunger have longitudinally extending surfaces located at the plunger upper end portion, which surfaces cooperate and limit rotation of the body with respect to the plunger. An upper fluid port is located in an upper end of the body, while one or more lower fluid ports are located in a lower end of the body.

Abstract: A system for use in monitoring, measuring, computing and displaying the rate of compression of aircraft landing gear struts, experienced while aircraft are executing either normal or hard landing events. Further by measuring the vertical compression rate of the landing gear strut, thus with aircraft hull angle correction to horizontal, determining the vertical sink-rate of the aircraft, as it comes into initial contact with the ground. Accelerometers are attached to opposing sides of a compressible landing gear strut, monitoring and measuring parallel data streams; then identifying differential acceleration data streams, which computed through mathematical algorithms measure the collapse rate of the landing gear strut. Pressure sensors are attached to the working pressure within the landing gear strut, so to monitor in-flight landing gear strut pre-charge pressure, until such time as the pre-charge pressure suddenly increases, to detect the aircraft has come into initial contact with the ground.

Abstract: The present invention provides an apparatus, system and method for handling glass containers that has a takeout jaw assembly with a base with a first side, a second side and a groove. The groove extends from the first side to the second side and is adapted to fit an insert. The groove also has a recess with one or more flexible retaining tabs positioned to secure the insert and a yoke extending substantially perpendicular from the base.

Abstract: The action camera has a housing, a lens, and an image sensor located in a light path from the lens. A filter is operable to move between first and second positions, with the first position located in the light path and the second position located out of the light path. An actuator moves the filter between the first and second positions. The actuator includes an electromagnet and a magnet. One of the electromagnet and the magnet is fixed relative to the light path, while the other of the electromagnet and the magnet is movable relative to the light path and is coupled to the filter. The magnet has poles that interact with the poles of the electromagnet. As the electromagnet is energized, the magnet rotates. The polarity of the electromagnet is reversed in order to reverse the rotation of the magnet. The camera is also provided with a light source. When the light source is activated, then the filter is moved accordingly. The actuator is small and consumes little electrical power.

Abstract: A power generator has a mass that is capable of moving vertically up and down. A generator has a rotor and a stator. A shaft couples the mass to the rotor, with the shaft allowing the mass to move vertically up and down. The shaft has spirals that produce relative rotation between the shaft and the rotor. The mass can float on a body of water that is subject to fluctuating water levels, such as a tidal body or a lock, or the mass can be used on dry land. The mass has an interior cavity. When the cavity contains gas, the mass rises in the water. When the cavity contains water, the mass sinks in the water. When the mass has sunk, gas is introduced into the cavity. When the mass has risen, the gas is vented from the cavity.

Abstract: A downhole pump for a well has a barrel and a plunger. The barrel has a passage extending along the length of the barrel, with the passage having an inside diameter. The plunger has an outside diameter and is received by the barrel passage for relative reciprocal movement. One of the barrel or the plunger is equipped with wear rings, with a wear ring at one or at each end. The wear rings are made of a material that is harder than the material of the respective plunger or barrel. The wear rings provide protection from abrasion, particularly in a sandy well.

Abstract: A face mask has mask material and ties or ear loops coupled to the mask material. The face mask is flat until worn. The mask material has an outside and an inside, which inside is designed to be against the wearer's face when the mask is worn. A deformable nose strip is provided near a top edge of the mask material. The nose strip is preformed into a contour for fitting about a nose. The contour bows out from the inside to the outside. A wearer donning the mask intuitively knows to orient the contour to the wearer's nose, wherein the inside is automatically positioned against the wearer's face.

Abstract: A system for use in monitoring, measuring, computing and displaying the rate of compression of aircraft landing gear struts experienced while aircraft are executing either normal or hard landing events. A high speed computer attached to high speed cameras, or range-finders, mounted in relation to each of the landing gear struts are used to monitor, measure and record the landing gear compression rates and aircraft touch-down vertical velocities experienced by landing gear struts, as the aircraft landing gear initially comes into contact with the ground. The system also determines through landing gear strut compression rates if aircraft landing limitations have been exceeded.
