Abstract: A cleaning procedure for removing grease and oil from articles soiled with organic materials comprising using circulating cleaning fluid at least part of which is sterilized to limit living micro-organisms, is new. A cleaning procedure for removing grease and oil from articles soiled with organic materials comprises using a cleaning fluid of which at least part is circulated between a washing unit (1) in which it picks up organic materials from the articles being cleaned, and a treatment unit in which living micro-organisms biologically degrade the organic materials contained in the fluid. At least part of the fluid circulating in the cleaning installation is subjected to at least partial sterilization to limit or suppress the living micro-organisms present in the fluid. The Sterilizing system uses heat and/or radiation and/or UV rays and/or chemicals with a bactericidal and/or bacteriostatic action in a unit with at least one treatment chamber (2A) filled with a filtering material (2) which holds the living micro-organisms and contains nutrients for them that are preferably insoluble or only slightly soluble in the cleaning fluid. The first treatment chamber (2A) is linked to a second one (2B) which recuperates and stores the fluid from the first chamber and has a circuit to recirculate it back to the first chamber with a fluid recirculation circuit as well as a Sterilizing unit (12).

Patent CA-2526739-A1 (CA)
Inventor: NIEDERREITER JOHN F
IPC: F28D19/04
Filed: 2005-11-18
Abstract: Frosting and fouling are two of the most prominent concerns regarding heat exchangers, in particular, regarding heat exchange between hot and cold air flows for building ventilation. Frosting and fouling both cause a build up of material on heat exchange surfaces thereby increasing the thermal exchange resistance between the hot and cold air flows.  This document defines a heat exchanger that is based on the heat sink principle, like the heat wheel and reverse flow exchangers. However it differs from these in that the thermal mass or heat sink is a continuous body that passes through each fluid successively, perpendicular to each fluids direction of flow. In addition, because of its continuous nature and movement, the heat sink surfaces may be continually scraped clean by strategically placed scrapers

Abstract: A system is described for maintaining synchrony of operations among a plurality of devices hat have independent clocking arrangements. The system includes a task distribution device that distributes tasks to a synchrony group comprising a plurality of devices that are to perform the tasks distributed by the task distribution device in synchrony. The task distribution device distributes each task to the members of the synchrony group over a network. Each task is associated with a time stamp that indicates a time, relative to a clock maintained by the task distribution device, at which the members of the synchrony group are to execute the task. Each member of the synchrony group periodically obtains from the task distribution device an indication of the current time indicated by its clock, determines a time differential between the task distribution device's clock and its respective clock and determines therefrom a time at which, according to its respective clock, the time stamp indicates that it is to execute the task.
