Patent CA-2364702-A1 (CA)
Title: Agricultural seed meter
Inventor: HAGEN RUSSELL A
IPC: A01C7/12
Filed: 2001-12-07
Abstract: An agricultural seed meter is disclosed including a seed selection mechanism in the form of a belt or a drum having pockets and moving through a seed reservoir area for loading seeds into the pocket. A cut-off brush is movable between a singulating position and a volume metering position so that the meter may be used either as a singulating meter or for volume metering without changing, deleting parts or adding parts. In either mode, seed release is accurate and repeatable through the use of a retainer brush for holding the seeds in their associated pocket until the pocket, in a downward, curving path, passed beyond the end of the retainer brush, thereby releasing the seeds into a discharge conduit.

Title: Genetically modified t-cells, method for producing them and use thereof
Inventor: RITTER THOMAS
IPC: A61K35/12
Filed: 2001-06-08
Abstract: The invention relates to in-vitro genetically modified T-cells for preventin g allogenic transplant rejection in vivo, to methods for producing them and to  their use. T-cells of the transplant recipient are stimulated in vitro with cells of the transplant donor or with cells which express dominant MHC molecules and at the same time, transduced with immunomodulating genes by means of gene transfer. After the gene transfer, the transduced T-cells begi n to express the immunomodulatory genes. The gene transfer can be carried out using retro viruses, other viral vector systems or liposomes. The conditions  selected for the experiment, which result in the generation and expansion of  allo-specific T-cells, ensure that the T-cells migrate into the allogenic transplant and into the draining lymph nodes specifically according to the i n vivo application and can express the immunomodulating genes there. The invention provides an effective means of preventing the rejection of allogen ic transplants (cells, tissues, organs) and is therefore an effective means of inducing and maintaining tolerance of allogenic transplants (cells, tissues,  organs) in transplant medicine.

Title: Workpiece grinding method which achieves a constant stock removal rate
Inventor: MAVRO-MICHAELIS DANIEL ANDREW
IPC: B24B49/00
Filed: 2000-10-26
Abstract: In a method of grinding a component such as a cam, a reduction in the finish  grinding time is achieved by rotating the component through only a single revolution during a final grinding step and controlling the depth of cut and  the component speed of rotation during that single revolution, so as to maintain a substantially constant specific metal removal rate during the fin al grinding step. The headstock (12) velocity can vary between 2 and 20 rpm during a single revolution of the cam during the final grinding step, with t he lower speed used for grinding the flanks and the higher speed used during th e grinding of the nose and base of the cam. Using a grinding machine (10) havi ng 17.5 kw of available power for rotating the wheel, and cutting a grinding wheel in the range 80-120 mmdiameter, typically the depth of cut lies in the  range of 0.25 to 0.5 mm.

Title: Small scale cogeneration system for producing heat and electrical power
Inventor: GUYER ERIC C
IPC: F01K17/02
Filed: 2001-01-24
Abstract: A small-scale, space-heating and electrical power co-generation system includes a heater (104) and a pump (136) for supplying high-pressure water t o the heater (104). Within the heater, the high-pressure water is heated to at  or near its saturation or boiling point so as to produce both vapor (e.g. steam) and liquid (e.g., water) fractions. This high pressure, two-phase mixture is then provided to an expander (120) which expands the two-phase mixture to a lower pressure and, in the process, produces mechanical energy.  The expander (120) is coupled to an electrical generator (122) so that the extracted mechanical energy can be used to drive the generator and thus produce electrical power. The fluid exiting the expander is then provided to  a condenser (126). A space heating fluid (e.g., air or a separate water supply ) is brought into proximity with the condenser so that it may be heated.</SDOA B>
