Abstract: A reinforcing underlayment including dry uniform particles evenly applied to a wet bonding material layer on a surface of a substrate. The substrate, including the layers, is then cured to harden the one or more of the layers. A final coating or topcoat is applied to the cured surface of the substrate. The dry particles are evenly distributed onto the bonding material layer creating a uniform surface for subsequent coatings. The dry particles increase the strength of the liquid coatings increasing solid particle density within the coating system and thereby imparting properties not available for the liquid coatings. The present invention enables a user to easily introduce very heavy, dense, strong particles into a liquid coating and allows the user to apply very dense, heavy particles into and onto a wet bonding material layer followed by a subsequent wet topcoat layer which is cured as one contiguous material with reinforcement and underlayment strengthening coming from the added, dry particles.

Abstract: A rotary position sensor is formed with a self-lubricating bearing. The rotary position sensor includes a race which forms one bearing surface. A drive arm assembly forms a bearing element forming two mating bearing surfaces. For applications in which the bearing may be subjected to environmental conditions that could result in corrosion, one bearing surface may be formed from a corrosion resistant metal, such as stainless steel, while the mating bearing surface is homogeneously formed with the bearing element from a composite material which includes PFTE or Teflon. By homogeneously forming the bearing element from a composite material which includes Teflon, wear of the bearing element will not effect lubrication of the bearing.

Abstract: A slide bearing for a centrifugal pump in which the slide bearing is lubricated by the pumped medium and is composed of a stationary part disposed in the housing of the centrifugal pump and a rotatable part which is supported by the shaft of the centrifugal pump and interacts with the stationary part to give a sliding pair. One part of the sliding pair is composed of a composite material, especially carbon fibers or silicon carbide fibers in a matrix of PEEK, carbon or carbon combined with silicon carbide. The other part of the sliding pair has a sliding surface made of a hard metal material and supported by a support material. A bond produced in the molten state is formed between the hard metal material of the sliding surface and the support material which supports the sliding surface of the other part of the slide bearing. The resulting slide bearing can be used in chloride-containing and/or corrosive media and has a sliding surface that is not prone to undercutting corrosion.
