Abstract: A method comprises: storing, by a computing system, a relational data in a data lake; spinning-up, by an orchestration system of the computing system, an ephemeral computing node on a computing device of the computing system; importing, by the ephemeral computing node, a copy of the relational data from the data lake into a relational database management system (RDBMS) installed on the ephemeral computing node; after importing the copy of the relational data into the RDBMS, performing, by the ephemeral computing node, a computing process that runs within the RDBMS and that uses the copy of the relational data; and after completion of the computing process on the ephemeral computing node, spinning-down, by the orchestration system, the ephemeral computing node.

Abstract: A method and apparatus for chronologically combining fault data, repair data, and operational parameters for a railroad locomotive. Generally, this data is collected and stored in separate databases. The present invention teaches combining the data so that an ordered analysis reflecting the timing of faults, repairs, and operational information can be carried out to determine the root causes of the faults.

Abstract: A system and method of a combination and sequencing of a first cleaner around a blanket cylinder, a second cleaner around one of the rollers in an ink form roller assembly, and a fluid applicator around another one of the rollers in the ink form roller assembly effectively clean the press rollers and the blanket cylinder used in a printing machine.

Abstract: An eddy current sensor probe which includes first and second rigid end portions coupled together with a central portion comprising a flexible membrane. The flexible membrane includes indentations comprising sensor supporting regions. A differential pressure is applied across the membrane to position the sensors in a favorable location for collecting data related to the condition of the wall portion of hollow tubes.

Abstract: Methods and apparatus for removing a pollutant such as dust (33) from a fluid stream (34). A nested array of fibers (35) is provided in a substantially annular container (36) having openings in its inner (32) and outer (31) cylindrical sides of such size as to retain the fibers (35) within the container while permitting fluid (34) to pass through easily, and the pollutant-containing fluid stream (34) is passed through at least a substantial portion of the container (36) from a region (37) outside the outer side (31) to a region (38) inside the inner side (32). Thus a substantial fraction of the pollutant (33) is separated from the fluid stream (34) in a portion of the nested array (35) generally nearer to the outer side (31) of the container (36) than to the inner side (31).

Abstract: A method and apparatus for the internal or blind side sealing of a small local leak (such as a void in casting). The sealing is accomplished by first drilling a hole in the conduit or container where the leak is located and setting a blind side sealer apparatus in the hole. The device consists of a guide that fits loosely into a drilled hole; a slitted metal conical capping means having an outside diameter approximately the same as the drilled hole diameter; a sleeve; and a retractable stem. The slitted cone is filled with a viscous sealant and the slitted cone part of the sealer assembly is pushed through the hole. Once on the other side of the hole, the slitted cone expands enough to prevent it from backing out. When the stem is pulled outward, the slitted cone is forced against the pipe or container wall, spreading the sealant. The stem then snaps at a necked-down position, signaling completion to the operator.
