Abstract: A method and system for pre-processing a set of related files associated with an application driver and stored on a computer server system is disclosed. The set of files is analyzed in order to determine the application-specific loading sequence within the set of files. The loading sequence hierarchy is encoded into a file usage hierarchy data structure in order to enable the sorting and the packaging of the analyzed files into transmittable structured file archives sorted according to the proper loading sequence. Based on the packaging, the application driver is modified to replace in the body thereof a set of references to the packaged files with references to the transmittable file archives. When the application driver is downloaded to a client system the associated file archives are transmitted concurrently for optimal processing on the receiving system.

Abstract: A single acting dual piston positive displacement pump with alternating piston motion. A pump suitable for manual operation and operable at relatively high pressure such as 400 to 800 psig. A pump suitable for pumping corrosive liquids with the drive mechanism separated from the liquid lines. A pump housing with cylinder section and abutting manifold section, with the alternating reciprocating pistons in the cylinder section and the inlet and outlet openings in the manifold section, with the pistons projecting from the cylinder section opposite the inlet and outlet openings for connection to the piston drive mechanism.
