A Moineau style stator includes a helical reinforcement component that provides an internal helical cavity. A resilient liner is deployed on an inner surface of the helical reinforcement component. The helical reinforcement component includes a solder or braze material and is typically metallurgically bonded to an inner wall of a stator tube. In exemplary embodiments, the helical reinforcement component includes a composite mixture of solder and aggregate. Exemplary embodiments of this invention address the heat build up and subsequent elastomer breakdown in the lobes of prior arts stators by providing a helical reinforcement component. Solder reinforced stators tend to be less expensive to fabricate than reinforced stators of the prior art.

Spray assemblies for use in coating a regular or irregular internal surface of a cylinder, and methods for coating the inside of a cylinder are disclosed. The spray assemblies may include: a spray head comprising a nozzle for spraying a coating material on an internal surface of a cylinder; a support wand coupled to the spray head; and a roller sleeve rotatably connected to the support wand and configured to contact the internal surface of the cylinder and to rotate radially as the cylinder is rotated. The spray assemblies may be used to provide a consistent and repeatable coating thickness, regardless of cylinder internal diameter. In some embodiments, the spray assemblies may be used to coat the internal surface of a stator tube.

Steel bit bodies are manufactured in a production process that employs polystyrene patterns in a lost foam casting process. The patterns are machined to permit the formation of complex shapes that cannot be reproduced in simple patterns that are extractable from reusable, two-piece pattern molds or dies. The patterns are machined from a billet material according to a basic, programmed, five-axis machining process to form multiple copies of a reproducible complex pattern body. The process is modified to produce multiple copies of a modified design. Machining the complex patterns and producing variations by changing the machine program permit multiple bit patterns of variable forms to be produced without need for building an intermediate, reusable pattern mold that would require multiple mold pieces, thus eliminating the associated time and expense required in the creation of a new pattern mold for each variation of the bit design. The pattern is machined in a single chucking operation in a machine tool adapted for machining plastics in a three-dimensional global process. The plastic has a composition and a density that permit it to be machined into a pattern having relatively small, unsupported structural projections and smooth surface features.
