摘要: There is provided a heat dissipating device. An exemplary heat dissipating device comprises a thermally conductive plate that is adapted to be disposed adjacent to at least one heat generating device. The thermally conductive plate has surface features configured to promote turbulent airflow over the thermally conductive plate, the thickness of the surface features being approximately equal to or less than the thickness of the plate.

摘要: An apparatus for separating and extracting printed circuit boards in a computer system. More specifically, a basket assembly is provided through which a number of printed circuit boards may be attached to a motherboard. A card divider and extractor assembly including a card divider and card extractor is coupled to the basket assembly between each of the printed circuit boards. The card dividers provide structural and electrical isolation between the printed circuit boards. The card extractors provide a mechanism whereby printed circuit boards can be easily removed from the system while the system is operational.

摘要: Indexing apparatus is disclosed whereby a constantly rotating drive shaft can intermittently drive apparatus driven thereby. An arm carried by the drive shaft pivotally carries a second arm which has means for engaging a cammed surface whereby the pivoted arm is moved radially toward and away from the drive shaft. The rotated output member is mounted for rotation about the longitudinal axis of the drive shaft and includes a projection adapted to be engaged selectively by an engaging member on the pivoted arm as the pivoted arm is rotated in response to the positioning of the camming surface. In the preferred embodiment, the projection is an extended member and the engaging member is initially brought into contact close adjacent the drive shaft and moved radially outward in a decreasing amount whereby the rotated member is smoothly accelerated. Correspondingly, upon disengagement, the engaging member is moved radially outward in an increasing amount to smoothly decelerate the rotated member.
