Abstract: An acetabular shell component includes a solid substrate, a porous outer layer coupled to the solid substrate, a porous inner layer coupled to the solid substrate, and an inner bearing coupled to the porous inner layer. One or more adjuncts extend outward from the porous outer layer. Each adjunct includes an outer surface that defines a customized patient-specific negative contour shaped to conform to a positive contour of a patient's bone. A method for manufacturing the acetabular shell component using an additive manufacturing process is also disclosed.

Abstract: An in-line air pressure regulator for scuba diving is designed to augment an independent air supply system in the event of a failure of the primary pressure regulator. The in-line air pressure regulator comprises a small, encapsulated, spring-biased valve which is designed to reduce tank pressure to a level which is compatible with the spare, or backup, second stage regulator. In effect, it is a simplified auxiliary primary air pressure regulator.

Abstract: Apparatus for drying a web comprises a pair of spaced parallel plates defining a channel there between of predetermined thickness and length for receiving the web. The plates are provided with juxtaposed elongated openings respectively for injecting drying air into the channel on opposite sides of the web. Air under pressure is supplied to the openings to establish a high velocity laminar flow of air from the openings in opposite directions along the surface of the web. Air is evacuated from the channel on opposite sides of the web at a predetermined distance from said openings to maintain the heat transfer rate in the air higher than the heat transfer rate in the web.

Abstract: A pneumatic carcass tire having a replaceable tread belt modified by being molded with dual tread patterns of different configurations disposed on the outside and inside surfaces thereof to enable the more efficient and compatible use of the tread belt in alternate, reversible manner for different ground surface and prevailing weather conditions.
