Title: Method for controlling an amount of material delivered during a material transfer
Inventor: ASH RAYMOND HOUSTON
IPC: G01G13/12
Filed: 2000-11-22
Abstract: A method for controlling an amount of material delivered during a material transfer. This method includes the steps of inputting a target amount for a material to be delivered from a source location to a target location, updating the target amount during the delivery of the material using a predictive model-based algorithm, and updating the predictive model-based algorithm based on process performance data using a recursive least-squares procedure. An adaptive selection algorithm which is used to determine whether at least one previous predictive model-based algorithm parameter should be replaced with at least one new predictive model-based algorithm parameter in order to adapt the predictive model-based algorithm in response to a process change. A method for overlapping a delivery of at least one independently measured material with a delivery of a main material during a material transfer process.

Patent CA-2438975-A1 (CA)
Title: Wet combustion engine
Inventor: ST LAWRENCE THOMAS W
IPC: B09B3/00
Filed: 2003-08-28
Abstract: This invention relates to systems, apparatus and methods of operating a wet combustion engine and apparatus therefore, capable of biologically burning fuels within a wet combustion chamber within a bioproactor system, including but not limited to, organic carbon containing materials especially biological, hazardous or toxic waste contaminants, in an environmentally sensitive manner. An integrated computer control system that, proactively and pre-emptively, uses feeback from bio-sensors, to monitor, record and control applicable components of the bio-system, to optimize, replenish, and sustain exponential growth of selected life-forms, including but not limited to microbes such as bacterial. In the intake cycle, a suitably prepared fuel mixture is metered into the wet combustion diffusion separation membrane chamber located within the life-support chamber of the bioproactor. In the combustion cycle, diffusion and combustion rates are monitored and timed. In the exhaust cycle, products of combustion, including water and incomplete combustion by-products both organic and inorganic, are removed. The above cycles may be repeated sequentially. The subsequent accumulation of all of the exhaust cycle's products of combustion may be collected, stored, classified, separated, recycled or discharged. Some of the potential energy released during the combustion cycle's reaction directly results in the conversion of wastes, the generation of gases and, in the case of organic carbon fuels, the generation of water. Other uses of the kinetic and potential energy released by this engine include, but are not limited to the, mechanical movements of actuators, and heat transfer to heat exchangers.
