Abstract: A bung assembly for closing an opening in a turret of a cryostat has a camera housing and bung body that is mechanically dimensioned to fit the opening, and is provided with a sealing arrangement for forming a gas-tight seal between the bung body and the turret.

Abstract: The apparatus for filtering and dispensing drinking water is disclosed which includes a container having an interior space with a dividing wall defining a first chamber for receiving unfiltered water and a second chamber for storing filtered drinking water, wherein a passage is formed through the interior wall adjacent a bottom surface of the container to provide fluid communication between the first and second chambers, and wherein at least one multi-layered filter pack is disposed across the passage to filter water flowing from the first chamber to the second chamber under force of gravity.

Abstract: A portable bottle for filtering drinking water is disclosed that includes a bottle having a threaded opening, a cover for cooperating with the threaded opening of the bottle and including a top wall having a plurality of internal engagement lugs depending downwardly from an interior surface of the top wall, a filter cartridge including an end cap having a circumferential side wall that includes a plurality of engagement ribs for cooperating with the engagement lugs of the cover, and a spout including a compressible circumferential flange configured to be positioned between the interior surface of the top wall of the cover and the upper surface the end cap of the filter cartridge to provide a resilient biasing force therebetween.

Abstract: A crowd control mechanism for a power shovel includes an extendible dipper handle having an extended position and a retracted position. A double acting hydraulic cylinder having a an extendible ram has one of the cylinder and the ram fixed to the dipper handle and the other of the cylinder and the ram is stationary relative to the dipper handle. At least one of the cylinder and the ram have at least one of a blind end port and a rod end port, and at least one of the cylinder and the ram have the other of the blind end port and the rod end port, wherein hydraulic fluid flowing into the cylinder through the blind end port urges the ram toward an extended position to extend the dipper handle, and hydraulic fluid flowing into the rod end port urges the ram toward a retracted position to retract the dipper handle. Hydraulic fluid flowing into and out of the cylinder is controlled by one or more pilot operated poppet valves.

Abstract: A method and apparatus for performing packet processing is described. A signal having a preamble sequence is received. A detection parameter estimate is derived from the preamble sequence. The detection parameter estimate is evaluated to process at least one packet in the signal.

Abstract: A photographic display apparatus which comprises a substrate, as for example, a glass sheet having a mirrored surface thereon. An orthochromatic, high contrast, graphic arts copy film, or so-called "ortho film," having a positive visual image is disposed on the substrate and is covered by a transparent sheet. These three components may then be secured together by conventional means. The image on the ortho film is viewed through the transparent sheet against the mirrored surface of the substrate and which presents a unique visual appearance, similar to that of an image etched onto glass. The ortho film may be made by using a positive print of the desired image and generating a negative film therefrom through conventional photographic techniques. This negative film may be printed and enlarged if desired during the printing process in order to produce a positive ortho film sheet which is used in the above photographic display apparatus.
