Title: Process for clarifying milkhouse wastewater
Inventor: MALCOLM IAN
IPC: C02F1/52
Filed: 1995-03-31
Abstract: A process and apparatus are described for clarifying milkhouse wastewater, which is rich in phosphorous and also contains colloïdal and suspended solids.  This wastewater is obtained during the washing of milk pipelines of a diary milking system. The wastewater is collected in a treatment vessel, with the ratio of suspended solids to phosphorus in the wastewater being lowered either before entering or while in the treatment vessel. To this wastewater of lowered suspended solids:phosphorus ratio, there is added sufficient calcium, preferably in the form of lime, to react with all of the phosphorus in the wastewater to form calcium hydroxyapatite precipitate. It has been discovered that, by lowering the ratio of suspended solids:phosphorus, sufficient calcium hydroxyapatite precipitate is formed to sweep with it during settling substantially all colloïdal and suspended solids thereby leaving a clear, environmentally safe effluent water. The ratio of suspended solids:phosphorus is easily lowered by initially flushing the system with a small quantity of water and separately collecting this initial flush water having a high concentration of suspended solids.

Title: Method and apparatus for providing real-time animation utilizing a database of postures
Inventor: LACHAPELLE PIERRE
IPC: G06T13/40
Filed: 1998-02-27
Abstract: This invention relates to a method and apparatus for animating a synthetic body part, more particularly to a 3D-animation system and method utilizing a database of basic postures. In a first step, for each frame, a linear combination of the basic postures from a database of basic postures is obtained by minimizing the Euclidean distance between the displacement of critical points. The displacement information is supplied externally, and typically can be obtained by observing the displacement of physical markers placed on a moving physical body part in the real world. For instance, the synthetic body part may be an expression of a human face and the displacement data is obtained by observing physical markers placed on the face of an actor. The linear combination of the postures in the database of postures is then used to construct the desired posture. Postures are constructed for each time frame and are then display consecutively to provide animation. The invention also provides a computer readable storage medium containing a program element to direct a processor of a computer to implement the animation process.
