Abstract: A method may comprise placing a plug in a chamber of a housing, sending a carbide powder through the one or more access ports such that the carbide power is directed around the plug and deposited on the inner surface, and removing the plug from the chamber. A rolling element assembly may comprise a housing having an outer surface and inner surface, carbide powder on the inner surface, and a rolling element attached in the chamber with a portion of the rolling element extends from the chamber, wherein the rolling element is in contact with the carbide powder deposited on the inner surface.

Abstract: A racking board for retaining tubulars is disclosed having a first finger, a second forger positioned generally parallel to the first finger and with a gap between the fingers serving as a storage area for tubulars. A first inflatable member is supported adjacent to the first finger and a second inflatable member is supported adjacent to the second finger, the inflatable members adapted to expand radially into the gap upon inflation so as to capture and retain the tubular. In some embodiments, a single inflatable member in employed to expand into the gap and retain the tubular. A method of racking tubulars is disclosed using elongate, inflatable restraints.

Abstract: Methods and systems for transferring pipe (including tubulars such as casing, tubing, drill pipe, etc.) or stands of pipe from one location to another in a wellbore derrick, e.g. from a fingerboard to a well center.

Abstract: A combination seat cushion and tote bag device broadly comprises a seat cushion portion and a tote bag portion. The seat cushion portion includes a padded cushion and a flexible outer covering surrounding the cushion. The outer covering presents a front face with opposed upper and lower edges. The tote bag portion includes a back panel and a front panel defining a storage pouch. The tote bag portion is coupled with and depends from the front face of the outer covering. The front panel is constructed from a generally transparent material enabling viewing of contents of the pouch through the front panel of the pouch.

Abstract: A chair accessory device comprises first and second tote bags, and a coupling panel coupling the bags together. Each tote bag includes an inner and an outer panel. The coupling panel includes opposed first and second, each end attached to one of the bags together. A first shoulder strap is coupled with the first bag and a second shoulder strap is coupled with the second bag. The device further includes bag attachment structure for selectively securing the first and second bags in close proximity to each other.

Abstract: An adjustable sweatband for uniform caps and the like having a flat generally tubular resilient casing with one open end and one closed end and a vertical opening adjacent the closed end; a semi-rigid regulator strap passing through the casing having one end extending beyond the vertical opening and fixed to the casing and the other end extending beyond the casing open end; and circumferentially spaced tabs on the strap fixed end and circumferentially spaced openings on the strap free end.
