Abstract: An apparatus for rotatably hanging a tubing string in the wellhead of a well casing. The apparatus includes a tubing hanger shell that has a mandrel rotatably mounted therein. The mandrel has upper and lower ends with the upper end connected to a tubing rotator and the lower end engaging a tubing string. To facilitate the connection and disengagement of the mandrel to the tubing rotator, a hollow sleeve is used to couple the parts together. The hollow sleeve is received within the mandrel and has longitudinal splines which engage corresponding splines on the mandrel to transfer rotational energy from the rotator to the mandrel. The rotator is removed from the mandrel through the application of force, and through movement, in a direction parallel to the longitudinal axis of the tubing string.

Abstract: The assembly comprises an electrically insulated linear array of a plurality of active plates working in conjunction with common return plate means to provide a line of capacitors. The electrically insulated active plate array and common return plate means extend through a column of multi-phase fluid. A discrete oscillator circuit is positioned adjacent to and is permanently connected to each active plate for charging and discharging it. Means are provided for sequentially enabling the oscillator circuits to produce signals which are each indicative of the dielectric constant of the thin horizontal slice of fluid extending between the active plate and the return plate means. The signals are collected by a microprocessor which analyzes them to provide a dielectric constant profile of the fluid column. Interfaces of phases can be located from the profile and the composition of the fluid phases can be determined.

Abstract: The apparatus is comprised of a platform with a teeing mechanism operated by a user. The user depresses a lever arm that depresses a tee and that activates a dispensing mechanism that feeds golf balls to the tee in its depressed position. The mechanism is comprised of a set of levers, a ratchet and an axle which extends into a reservoir of gold ball dispenser. The reservoir includes a hole leading to a chute that terminates at a vertical tube in which moves a depressible tee. On the axle, within the reservoir, is a flexible rotating disk with a plurality of oval holes. As the disk rotates, balls in the reservoir fall into the holes, and as the holes pass over the hole in the reservoir, the balls fall into the chute and onto the tee. The ratchet coordinates the motion of the flexible disk so that one ball is moved into position over the hole in the reservoir for each depression of the tee.

Abstract: Pyrohy makers usually comprise ordinary stamp out plastic molds or multiple molds, both of which often present difficulties in sealing the pyrohies and/or releasing same from the molds.
