Publication number: 20110291506Abstract: Centrifugally decoupling mechanical bearing systems provide thin tensioned metallic ribbons contained in a support structure. This assembly rotates around a stationary shaft being centered at low speeds by the action of the metal ribbons. Tension springs are connected on one end to the ribbons and on the other end to the support structure. The ribbons pass through slots in the inner ring of the support structure. The spring preloading thus insures contact (or near-contact) between the ribbons and the shaft at rotation speeds below the transition speed. Above this speed, however, the centrifugal force on the ribbons produces a tensile force on them that exceeds the spring tensile force so that the ribbons curve outward, effectively decoupling them from mechanical contact with the shaft. They still remain, however, in position to act as a touchdown bearing in case of abnormally high transverse accelerations.Type: ApplicationFiled: May 31, 2011Publication date: December 1, 2011Inventor: Richard F.

Publication number: 20110291539Abstract: In a slide assembly, an adjustable detent mechanism enables the detent and, therefore, the holding force, between a slide member on a pull-out component and an opposite slide member to be adjusted based on the application and load conditions for the pull-out component. The adjustable detent mechanism may include a base having symmetrically-disposed detent arms and associated legs which interact with respective adjuster cams symmetrically disposed on an adjustment dial. The dial is co-axial with, and is received in, the base, and both are coupled to one of the slide members. The opposite slide member has two symmetrically-disposed retention tabs that interact with respective ones of the detent arms to adjust the holding force between the slide members. The dial's range of rotation may be defined by the interaction between a pin disposed on the base and a rotation restriction guide that is defined through an undersurface of the dial.Type: ApplicationFiled: May 20, 2011Publication date: December 1, 2011Applicant: ACCURIDE INTERNATIONAL, INC.Inventor: BENJAMIN SANCHEZ LEAL

Publication number: 20110291540Abstract: A cabinet includes one or more shelves that each include a substrate, a removable shelf liner, and a removable end cap. When the removable shelf liner or removable end cap needs to be replaced, either one or both of the removable shelf liner and removable end cap can be easily removed and replaced without removing or replacing the shelf. In addition, the sides and back of the cabinet preferably contain a dado joint so that the shelf substrate is captivated within the sides and back of the cabinet. The cabinet may also include metal rods to support each shelf substrate. The sides of the cabinet are attached by screws passing through the sides into the metal rods so there is a direct metal-to-metal connection. The combination of the metal rods and captivated shelves provides a cabinet that is very strong and durable, and can be repaired very easily and economically.Type: ApplicationFiled: June 1, 2010Publication date: December 1, 2011Inventors: Richard Dean Davidson, Len Alan Coates
