摘要： A VTOL rotor assembly for a compound VTOL aircraft, the VTOL rotor assembly having a rotor sleeve, a pair of rotor blades which are extendable from the rotor sleeve for vertical take off and landing and retractable to the rotor sleeve as forward air speed exceeds the stall speed for the compound VTOL aircraft, and a rotor hub for connecting the rotor sleeve to a rotor power assembly. Rotor blade motivators controlled by a rotor blade controller determine the pitch of the respective rotor blades through interaction of the pilot of the VTOL aircraft with the rotor blade controller.

摘要： An electrical transmission assembly for drill pipe segments for a drill string for oil wells and gas wells. A resilient pipe segment lining having an embedded lining conductive element extending from a first lining inductive element to a second lining inductive element is affixed to the interior surface of the pipe segment. A support sleeve dimensioned for slidable mating with the interior surface of the resilient pipe segment lining has an embedded sleeve conductive element extending from a first sleeve inductive element to a second sleeve inductive element. The position of the first and second sleeve inductive elements respectively provide for them to be positioned radially and longitudinally proximal to the first and second lining inductive elements respectively as the pipe segments are threaded together.

摘要： A positive displacement, shock dampening, plunger pump having a plunger chamber with a pressure chamber and a shock chamber, the plunger chamber having a plunger chamber longitudinal wall and the shock chamber having a shock chamber end wall. The plunger pump has a shock bearing slidably positioned in the plunger chamber and a shock spring positioned in the shock chamber between the shock bearing and the shock chamber end wall. The plunger pump has a pump plunger reciprocally positioned in the plunger chamber and extending from the shock chamber to the pressure chamber through a plunger port in the shock bearing. The shock bearing is in slidable contact with the plunger chamber longitudinal wall and the plunger longitudinal surface. The plunger pump has a reciprocating drive connection mechanism for interconnecting the pump plunger with a plunger drive mechanism.
