  • Patent number: 4241797
    Abstract: An improved impact tool being attached to a drill stem about ten (10) or more feet above the drill bit, and in drilling mud flows through the impact tool to the drill bit when the well is being drilled. When the drill becomes stuck, plunger means is inserted through the drilling mud passage way from the ground level and is forced down to the impact tool by pressure of the drilling mud, and on reaching the impact tool, it engages a lip forming surface at the upper end of the impact tool and seals off the flow of drilling mud. The pressure placed on the drilling mud flowing from ground level forces a set of sleeves to move downward against the force of a helical spring, causing the drilling mud to flow through a jet contoured nozzle for directing the drilling mud toward the stuck drilling bit for thereby dislodging the drilling bit.

  • Patent number: 4166390
    Abstract: A scanning radiometer having a series of laminations forming a tightly bonded sandwich structure each being electrically insulated from adjacent ones thereof, said series including a thermometric or thermo responsive material, a heat pump functioning material, a heat sink functioning material, and an insulator functioning material, and in which the thermo responsive material is formed of a set of matrix of thin metal alternately with absorptive or blackened portions, each forming opposite arms of a Wheatstone bridge.The use of the term "thermoelectric or thermoresponsive material" designates a metallic or other electric resistor whose resistance is temperature sensitive and when measured, is an indicator of its temperature. "Heat pump functioning material" is a thermoelectric device that tranfers or "pumps" heat from one of its two surfaces to the other when an electric current is supplied to its terminals.

  • Patent number: 4162855
    Abstract: A lightweight magnetic stirrer apparatus which may be positioned for rotation in a fluid containing vessel, having a magnetic rotor assembly including a generally vertical center hub on which is mounted a generally horizontal magnetic impeller. The rotor assembly is rotatably mounted in a positioning cage which generally positions the rotor assembly within the vessel and prevents it from contacting the walls of the vessel to allow the rotor assembly hub to rotate free relative to the vessel in the cage under the influence of an exterior magnetic drive. The magnetic stirrer apparatus is also provided with a cage in which the legs are totally removeable so as to make it any size for different beakers. Furthermore, the magnet may be removed completely from the cage so that it may be dropped into the neck of a bottle and the magnet per se used by itself. High lubricity bearing surfaces of the hub and cage reduce frictional forces and allow rotation of the impeller at very low speeds.
