Abstract: An improved valve plate assembly is disclosed herein which incorporates a spring retainer which is press fitted into a suitable opening provided in the upper plate of a multiple piece valve plate assembly. The spring retainer element may be suitably designed for use with either coil or leaf type springs. An improved attachment arrangement for connecting the leaf spring to the valve member is also disclosed.

Abstract: Apparatus for vertically separating a motor drive shaft from a load shaft while maintaining alignment between the motor drive shaft and the load shaft so that the load shaft and associated apparatus may be accessed for repair or replacement.

Abstract: Nuclear reactor coolant pump having a tooling boom mounted on the periphery of the motor stand of the pump for transferring pump components through openings in the motor stand during performance of maintenance on the pump. The tooling boom comprises an articulated arm mounted on the periphery of the motor stand with a gripping mechanism attached to the arm at the end opposite the arm's attachment to the motor stand. The gripping mechanism is capable of having pump components firmly attached thereto so that when the articulated arm is swung in the horizontal plane, the pump components may be transferred between the inside and outside of the motor stand.

Abstract: An electrostatic, liquid spray, rotary atomizer has an atomizer housing, a power supply within the housing and an atomizer cup at a front end of the housing. The atomizer cup, which is formed of a non-conductive material, has several elongate conductive pathways embedded in the body of the cup. Each conductive pathway has one end exiting an outer surface at a rear end of the cup for receiving the charge from the power supply and another end exiting an inner surface at a front end of the cup for conveying an electrical charge from the power supply to the liquid (paint) particles passing through the atomizer cup. An electrode is provided for maintaining a small voltage at the access hole.
