Abstract: A fiberglass laminate used in fabricating a composite pile comprising a plurality of fiberglass type layers and an impervious tube array. A tubular composite pile construction includes the laminate as well as plastic inner and outer skins and a resin injected into the laminate. A method of fabrication includes providing a mandrel, wrapping a plastic inner sleeve about a bladder on the mandrel, wrapping the fiberglass laminate and wrapping a plastic outer skin about the laminate. Lastly, a resin is injected into the laminate to substantially fill between the inner and outer skins.

Abstract: A high speed shaftless rotor construction is disclosed including a method of sequentially building up the rotor to facilitate disassembly for reworking and maintaining precise alignment of the reassembled elements. End turn supports are matched and preliminarily assembled with bolts to the core and the parts machined to achieve desired tolerances. After machining, the end turn supports are separated from the core, matched with end shaft fittings and additional machining carried out, after which the turn supports are separated from the end shaft fittings and reattached with the core. The shaft fittings are realigned with the assembled end support fittings and bolted into position after which final machining can be completed. All elements are then disassembled and the parts deburred and cleaned to eliminate any contamination prior to winding the field coil.

Abstract: According to the invention, an insulator is provided at the axial ends of a rotor core. The insulator has radially spaced rows of notches at intervals approximately equal to the diameter of the winding wire for guiding placement of the turns of the winding at a predetermined location. After completion of the first turn, the wire is skewed at a first angle with respect to the plane of the first turn to coincide with the second notch and the remainder of turns in the first layer in turn completed in substantially parallel relationship. At the completion of the last turn of the first layer, the wire is crossed over the next to the last turn, skewing the winding in an opposite direction and situating the wire in the valleys formed between the successive turns in the first layer. The sequence continues alternately for the remaining layers.
