  • Patent number: 7353615
    Abstract: The tilt detector has a container with a receptacle located therein. The receptacle has open and closed ends. In its normal, upright orientation, a first mass is located inside of the receptacle. A second mass is located adjacent to the open end of the receptacle. When the receptacle is in its normal, upright orientation, the second mass is located above the receptacle and blocks the exit of the first mass from the receptacle even when the first mass moves in response to vibration frequencies to which the first mass is sensitive. When the receptacle is tilted beyond a predetermined angle, the second mass moves from its blocking position so as to allow the first mass to exit the receptacle. A tilting indication occurs when the first mass has exited the receptacle.

  • Patent number: 7278476
    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 has upper and lower fluid ports to allow the ingress and egress of well fluids from the body as the plunger reciprocates. If the tool fails, it typically does so by the body breaking into two parts, namely the upper body and lower body, at the upper fluid ports. The upper end of the plunger is provided with a fishing neck. Thus, upon failure of the body at the upper fluid ports, the fishing neck is exposed and can receive a fishing tool for retrieval of the tool and the pump.

  • Patent number: 7274310
    Abstract: A system for use in monitoring, measuring, computing and displaying the Kinetic Energy generated and experienced while aircraft are executing either normal, overweight or hard landing events. Pressure sensors and motion sensors are mounted in relation to each of the landing gear struts to monitor, measure and record the impact loads and aircraft touch-down vertical velocities experienced by landing gear struts, as the aircraft landing gear initially comes into contact with the ground. Velocity adjustments are made to correct for errors caused by landing gear per-charge pressure and landing gear strut seal friction. The system also measures the landing loads experienced by each landing gear strut during the landing event and determines if aircraft limitations have been exceeded.

  • Patent number: 7270690
    Abstract: The separator has a vane assembly made up of a number of corrugated vanes that provide serpentine paths for the gas stream therethrough. As the gas stream flows through the serpentine paths, it changes direction and liquid in the gas stream impacts the surfaces of the vanes. The upstream section of the vane assembly has roughened surfaces to decrease the surface tension of the liquid, thereby causing the liquid to coalesce. The downstream section of the vane assembly has smooth surfaces so as to increase the surface tension of the liquid. The vane assembly is followed by filters, which capture the liquid that passes through the vane assembly. The vane assembly coalesces the liquid to enable the filters to operate more effectively.

  • Patent number: 7231754
    Abstract: A horse blanket has a back portion and side portions that extend down from the back portions. The side portions couple to each other at a front chest area. The straps that couple the chest area side portions together are elasticized. A neck opening above the chest area is elasticized around the entire circumference. The areas of the blanket near the horse's front legs are also elasticized. The elastic portions allow the blanket to fit snuggly around the horse's neck and front area, while allowing flexibility for the horse to exercise. In another embodiment, the blanket has a notch in the neck opening at the mane and another notch at the rear for the dock of the tail. The notches reduce the wear of the blanket on the mane and tail.

  • Patent number: 7225757
    Abstract: A method of cleaning bedding sand soiled with animal manure removes the bedding sand from an animal bedding area. An aqueous slurry of the bedding sand is made. The slurry is subjected to cyclonic action so as to separate the sand from the manure. The separated sand is then respread back into the animal bedding area for reuse. The clean bedding sand is free of organic contaminants such as manure, urine and milk. In addition, the bedding sand may contain inorganic contaminants such as clay and silt particles as well as fine particles which are undesirable in a bedding material. Processing the sand removes these inorganic contaminants and fine particles to produce a superior bedding sand for animals.

  • Patent number: 7199483
    Abstract: A tidal power generator has a floating vessel hull that is subject to rising and falling water levels so that the hull moves vertically up and down. Linear-to-rotary converters are coupled between the vessel hull and a fixed object. The converters allow the hull to move vertically while constraining the horizontal movement of the hull. The converters convert the vertical movement of the hull into rotary movement, which is then used to drive an electrical generator. A harborage is provided to protect the hull and the converters and to regulate the water level for the vessel hull as well as become a fixed object relative to the vessel from which a change in relative position causes power to be developed. If the hull is subject to tidal variations, vertical movement of the hull can be desynchronized from the tidal variations so as to store energy during slack tides.
