Abstract: Systems and methods for storing and accessing data. Example embodiments may perform optimization based on patterns of requests received by the system and relations between data sets identified by the system. Example embodiments may identify restrictions on a data set based on a different data set. Conditions for automatically algebraically partitioning the data set based on a constituent of a different data set may be evaluated, including evaluation of the relationship between the data sets and identification of a pattern of statements restricting the data set using the same logical structure. If the conditions are met, component data sets and a partition data set may be algebraically defined based on ranges applied to constituent(s) of the other data set. The component data sets may also be realized in storage to physically partition the data set.

Abstract: The disclosed invention relates to a process and apparatus for separating a first fluid from a fluid mixture comprising the first fluid. The process comprises: (A) flowing the fluid mixture into a microchannel separator in contact with a sorption medium, the fluid mixture being maintained in the microchannel separator until at least part of the first fluid is sorbed by the sorption medium, removing non-sorbed parts of the fluid mixture from the microchannel separator; and (B) desorbing first fluid from the sorption medium and removing desorbed first fluid from the microchannel separator. The process and apparatus are suitable for separating nitrogen or methane from a fluid mixture comprising nitrogen and methane. The process and apparatus may be used for rejecting nitrogen in the upgrading of sub-quality methane.

Abstract: A continuous controlled atmosphere brazing system includes a dry-off oven for driving off moisture from materials to be brazed, a pre-heat section for pre-heating the material and a brazing furnace for brazing the materials. Heated gas produced in the pre-heat section and the brazing furnace is conveyed along a flowpath to the chamber of the dry-off oven to provide substantially the sole source of heat for the oven. The flowpath for the heated gas is defined by a series of tubes in communication with each component of the brazing system and intermediate manifolds disposed between components. The discharge mouths of the tubes open into the oven chamber at the suction side of recirculation fans operating within the oven. The overall temperature of the oven can be regulated by controllably mixing ambient air with the heated gas in relation to the oven temperature.

Abstract: An integrated circuit includes a plurality of interconnected circuit modules having memory elements and logic elements therein. The modules collectively perform the operations of the integrated circuit. However, rather than testing the entire circuit and limiting the degree of fault coverage, individual modules can be tested on a module by module basis. To facilitate testing at the module level, the circuit includes a plurality of control cells connected to respective ones of the modules. Each of the control cells preferably includes a shift register latch for retaining a data signal corresponding to whether the respective module is to be sequentially tested or temporarily disabled. The control cells further comprise a pass-through transistor network for passing the system clock to one or more of the modules under test and for withholding the clock from the modules not under test.

Abstract: An integrated logic circuit according to the present invention includes a plurality of logic circuit elements, such as field effect transistors, for performing a combinational logic function, and at least one test controlled-impedance element for loading the logic circuit and causing a first digital output signal to be produced when the impedance of a logic circuit element under test is within a predetermined range and produce another digital output signal when the impedance of the logic circuit element under test is outside the predetermined range. The test controlled-impedance elements typically comprise field effect transistors and are sized in accordance with a series of constraints. The constraints are obtained by considering the operation of the circuit under various impedance fault conditions (high, low and intermediate) and deriving a series of size relationships between the impedance values of the logic circuit and test elements.

Abstract: The specification discloses an apparatus for washing the interior of an elongate, generally rectangular freight container. The apparatus includes a wash dolly and a transfer carriage adapted to carry the wash dolly into alignment with the open end of the container. A control system including electrical and hydraulic circuits causes the wash dolly to travel off of the transfer carriage, along substantially the entire length of the container, and back onto the transfer carriage. The wash dolly scrubs and sprays the interior of the container as it travels.

Abstract: A seal ring for sealing an annular space between two telescoped and relatively movable parts. The ring seats in a groove in one of the parts, and leaf springs urge the seated ring against the other part to effect the seal. The leaf springs include annealed or reduced-cross-section portions which provide relatively low-rate and long-travel spring characteristics to accommodate tolerance variations, dimensional changes of the ring as wear occurs, and thermal expansion or contraction of the sealed parts. The wearing surfaces of the ring may be covered by a plastic cap or anti-galling coating.
