摘要:
An improved air filter having a frame that permits collapse and compression of the entire filter to save costs associated with transportation and for other advantageous reasons. The ends of the filter frame open to permit collapse of the frame to reduce the volume thereof. The filter frame is made of frame members at opposing frame ends, and each frame member has web panels that open for collapse of the frame, and close for construction of the useful frame. The web panels have legs on opposite lateral edges to form a channel in which filtration media is inserted, and four frame members are attached at opposing ends to form a rectangular frame. The web panels open by removing a temporary fastener, such as adhesive, or by other means.

A scanning probe microscope comprises a probe module. In some embodiments the module is easily removed from the lateral and vertical scanning mechanisms. The module further comprises one or more vertical motion actuator that may be controlled by a multi-path feedback control loop. By coupling the second vertical motion actuator directly to the probe the speed of the scan may be increased over the speed of prior art microscopes. The feedback loop is part of the probe microscope and feedback paths may be independently designed to create independent control of multiple paths.

摘要:
A method and apparatus are provided for detecting and handling an instruction flush in a microprocessor system. A flush mechanism is provided that is distributed across all of the execution units in a data processing system. The flush mechanism does not require a central collection point to re-distribute the flush signals to the execution units. Each unit generates a flush vector to all other execution units which is used to block register updates for the flushed instructions

A communication system, method, computer program product, and apparatus include common equipment shared between multiple independently administered networks. The common equipment is reconfigurable and expandable and provides changed communication capacity and functions when additional elements are added or reconfigured. Configurable features include, for example, communication bandwidth, Quality of Service, and a number of communication satellites included in the communication system. The common equipment includes expandable elements including, for example, a single hub modem chassis that can expand to communicate with more than one communication satellite and a protocol processor that can share a protocol processing task with another protocol processors.
摘要:
A central floating device with a plurality of peripheral connection points and tethers. The tethers may be retractable, and are of sufficient length to allow the users some amount of spacing distance from each other. Each individual user thus maintains a separation from each other so as not to interfere with each other in the pool, lake, or body of water while remaining tethered together. The floating device may further include cup-holders, lights, storage compartments, and an anchor.

A method, an apparatus, and a computer program product are provided for detecting load/store dependency in a memory system by dynamically changing the address width for comparison. An incoming load/store operation must be compared to the operations in the pipeline and the queues to avoid address conflicts. Overall, the present invention introduces a cache hit or cache miss input into the load/store dependency logic. If the incoming load operation is a cache hit, then the quadword boundary address value is used for detection. If the incoming load operation is a cache miss, then the cacheline boundary address value is used for detection. This invention enhances the performance of LHS and LHR operations in a memory system.

The present invention relates to a process for the synthesis of oxandrolone from mestanolone. The process comprises the steps of: (a) oxidizing mestanolone to form 17β-hydroxy-17α-methyl-5α-androst-1-en-3-one; (b) hydroxylating the 17β-hydroxy-17α-methyl-5α-androst-1-en-3-one to form 1α,2α, 17β-trihydroxy-17α-methylandrostan-3-one; (c) cleaving the 1α, 2α, 17β-trihydroxy-17αmethylandrostan-3-one to form 17β-hydroxy-17α-methyl-1-oxo-1,2,-seco-A-nor-5αandrostan-2-oic acid; and (d) reducing the 17β-hydroxy-17α-methyl-1-oxo-1,2,-seco-A-nor-5α-androstan-2-oic acid to form oxandrolone.
