Patent CA-2095788-A1 (CA)
Title: Local reclamation system
Inventor: BENSKIN CHARLES O
IPC: C02F1/32
Filed: 1993-05-07
Abstract: ABSTRACT      The local reclamation system includes an accumulation tank for a soiled solution.  A tank outlet valve selectively allows a flow of the solid soiled solution into the remainder of the system. A blend conduit leads from the outlet valve.  An oxidizing supply selectively provides an oxidizing agent to said soiled solution downstream of the outlet valve in the blend conduit.  A blend pump receives the soiled solution with oxidizing agent to promote the flow of the soiled solution through the system and a more uniformed disposal of the oxidizing agent throughout the solution.  A six stage filter section selectively removes particulate matter.  A biologic stage promotes a sterile reclaimed solution and a solution accumulator  accumulates  and  stores  the  solution.    Repeated injections of oxidizing agents occur before filter stage sections and pumps.   The reclaimed solution can be reused or discharged without penalty.

Inventor: BIXBY JOY P
IPC: H04Q3/00
Filed: 1991-09-30
Abstract: A data communication method and apparatus is presented that allows communication in a distributed heterogeneous network.  Communications managers reside in local processing environments and are responsible for interfacing local end users with the remainder of the heterogeneous network. Each communications manager receives distribution units from end users, the distribution units being assigned various priority levels and levels of assurance. Within each communications manager, an adjacent communications manager is determined in accordance with a communications path to a destination for the distribution unit. The distribution unit is then configured according to a network protocol stack existing between the communications manager and the adjacent communications manager, and the distribution units are transmitted according to priority.  Each communications manager can have any number of adjacent communications managers each communicating through different network protocol stacks. Also described is load distribution among a complex of processors that share common functions, as well as control of information flow between adjacent communications managers.
