Abstract: A golf training apparatus device may include a ball plate with golf ball spaced markings on a surface; a ball slide including a channel configured to slideably receive the ball plate as a linear guide and configured to enable linear sliding motion of the ball plate relative to the ball slide; a foot plate; a foot slide including a channel configured to slideably receive the foot plate as a linear guide and configured to enable linear sliding motion of the foot plate relative to the foot slide, the foot slide is rotatably coupled to the ball slide, and may include a telescoping member rotatably coupled to one of the slides, and may further include a swing slide rotatably coupled to a swing plate, where the swing slide may be slidably coupled to the ball or foot plate, and the foot plate may include feet.

Abstract: An apparatus for applying segmented ceramic coatings includes means for supporting and moving one or more substrates; one or more heat sources disposed proximate to one or more substrates, wherein at least one of the heat sources is positioned to apply a heat stream to pre-heat a thermal gradient zone on a surface of a substrate; a material deposition device disposed proximate to one or more heat sources, wherein the material deposition device is positioned to deposit a material on a deposition area located behind the thermal gradient zone on the surface; and means for monitoring a surface temperature of one or more substrates.

Abstract: A gas turbine abradable seal is prepared by plasma spraying an oxidation resistant metallic material and boron nitride. The resultant structure comprises a metallic matrix encompassing a lubricating amount of boron nitride, with porosity of less than about 15 percent and a fabricated surface roughness of less than about 600 microinches. The reduced surface roughness and substantially reduced permeability of this seal provide substantially enhanced engine efficiency, and improved durability.

Abstract: An apparatus and method are described for simultaneously thermal spraying at least two types of powders onto a substrate, wherein both powder types are carried by a single spray stream and impacted upon the substrate. According to the invention, the different powder types are injected into the spray stream through separate powder ports in such a manner that there is substantially no mixing of the powder types in the spray stream. The spray system and substrate being sprayed are moved relative to each other to produce a homogeneous sprayed powder deposit.
