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.

Abstract: An improved arm chair coaster formed of a main plastic container or body of elongated shape and closed for retaining in bulbuous end sections a weighted quantity of sand, gravel or shot, a wood, plastic or heavy cardboard block member of square or rectangular cross section secured to a mid or intermediate portion of the main plastic body, a stabilizer plate and rivets securing the main plastic bag to the block member, and underside of the main plastic body being sprayed with a non-slip, sprayed foam rubber coating to secure it onto the arm of a sofa or arm chair, and a lip, rim, or scalloped edge extending around the flat upper surface of the block means forming a receptacle. The main plastic body may be a transparent or a translucent material and each end of the main plastic body have equal weighted amounts of the sand, gravel or shot. Velcro may be used as securing means where a Velcro section is provided on the arm chair or sofa for receiving the improved arm chair coaster of the invention.

Abstract: A thermometer system for blowing heated air having a temperature value close to the temperature value of body temperature directly onto the tympanic membrane from tubing apparatus, and measuring the temperature of the air as it returns from the membrane, the air having membrane temperature.

Abstract: A quick chucking die holder device for forging presses comprises an upper and a lower die holder and two adapter plates with dies fastened therein. Centering gibs are provided for centering the adapter plates within the die holders and spring loaded wedges make the chucking connection.

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.
