Abstract: A computerized information retrieval system having consistency among a sensory network portrayed in a visual display, a semantic network that establishes the logic of data organization and retrieval and a mechanical storage network that locates data in a memory structure, the networks having an architecture based on a life tree array that splits the search and storage paths into multiple paths for rapid access and retrieval in response to user queries.

Abstract: An improved brake equalizer apparatus for equalizing fluid pressure and damping shock waves or pressure surges in fluid lines of a fluid pressure-actuated system, such as a hydraulic brake system. The apparatus has a shorter reaction time than a conventional brake equalizer, and can be manufactured with smaller overall length and weight. An important feature of the apparatus which results in reduced brake equalizer reaction time is an improved brake equalizer piston. The piston of the invention is shorter than a conventional brake equalizer piston (the ratio of the inventive piston's length to the length of the shock absorber which it abuts is substantially less than 0.5, and is preferably equal to about 0.23). The piston of the invention is also lighter than a conventional brake equalizer piston, and is preferably made of a hard, non-compressible, self-lubricating material.
