    摘要： A reverse percussion device for use with hydraulic percussive drills is provided. The reverse percussion device includes a cycling piston, valve and anvil. The piston and valve move in opposing directions between low and high pressure passages automatically until a lodged drill bit is freed, thereby facilitating removal of the drill bit from the drilled hole and eliminating alternate loosening and tightening of drill string threads. The reverse percussion device preferably includes an automatic disabling feature which causes the reverse percussion operation to cease when the bit is free to retract normally.

    摘要： Glycerol or other reduced carbon sources may be used as a feedstock for the microbial production of chemical products under certain microaerobic conditions. For example, such production may occur under microaerobic or microrespiratory conditions in which electron acceptors are consumed in the reaction as quickly as they are added. In such reactions, the reaction product is at least as reduced as carbon source. Further, during such a reaction, at least some of the carbon source is used to generate cell mass. In addition, microorganisms with modified genomes are provided for carrying out the methods herein.

    摘要： A retaining-locking system for chain link fence slats includes specially notched fence slat elements having a pointed upper or lower end. The slat elements are sized and shaped to be interwoven between consecutive links of a chain link fence. A retaining-locking strip is formed of resilient material, and has an inner surface and an outer surface and at least one securing protrusion. The securing protrusion is sized and shaped to fit slidably within the notch. The protrusion is located on the outer surface of the strip. When the slat elements are interwoven into between consecutive links of a chain link fence with each of the notches aligned with one another, the retaining-locking strip inserted between the slat elements and the links, with the securing protrusion disposed within the slats, the strip will urge the slats toward the links, thereby retaining the slats within the chain link fence.

    摘要： A beverage dispensing apparatus being formed so as in use to provide a vortex motion in the mass of beverage flowing through the apparatus. In the vortexial flow, a low pressure area is produced at the center of the vortex so that the pressure in that region falls below equilibrium pressure and thus results in gas separating out from the liquid beverage. Since the gas breakout is achieved without the need for a flow restrictor, the pressure drop associated with these devices does not occur. Consequently, the beverage may enter the apparatus at a lower pressure. Moreover it has been found that a high quality head is formed on the draught beverage dispensed from the apparatus of the invention.

    摘要： A method and apparatus for handling an accessed bit in a page table entry is provided. When a page table entry is not present in a translation lookaside buffer (TLB), an electrical circuit causes a TLB miss exception and branching to a first software exception handler. The first software exception handler fetches the page table entry from main memory. The first software exception handler places the page table entry in the TLB. An electrical circuit determines whether an accessed bit of the page table entry has not been asserted. If the accessed bit is not asserted, an electrical circuit causes an accessed bit exception and branches execution to a second software exception handler. The second software exception handler asserts the accessed bit in the page table entry in main memory. The second software exception handler returns control back to the original memory access, causing execution to resume where it had left off prior to the TLB miss exception. This process may be practiced for an upper-level page table entry or a lower level page table entry.
