Patent CA-2280174-A1 (CA)
Title: High speed, high density electrical connector
Inventor: MCNAMARA DAVID M
IPC: H01R12/50
Filed: 1998-01-15
Abstract: A high speed, high density electrical connector for use with printed circuit boards. The connector is in two pieces with one piece having pins and shield plates and the other having socket type signal contacts and shield plates. The shields have a grounding arrangement which is adapted to control the electromagnetic fields, for various system architectures, simultaneous switching configurations and signal speeds, allowing all of the socket type signal contacts to be used for signal transmission. Additionally, at least one piece of the connector is manufactured from wafers, with each ground plane and signal column injection molded into components which, when combined, form a wafer. This construction allows very close spacing between adjacent columns of signal contacts as well as tightly controlled spacing between the signal contacts and the shields. It also allows for easy and flexible manufacture, such as a connector that has wafers intermixed in a configuration to accommodate single ended, point to point and differential applications.
Patent CA-2281591-A1 (CA)
Inventor: CHOI NAG JOON
IPC: F27B15/00
Filed: 1998-12-16
Abstract: A two step twin-single fluidized bed type reduction apparatus for fine iron ore, and a method therefor, are disclosed. The fluidizing of the fine iron ore is stabilized so as to improve the reduction degree and the gas utilization rate, and so as to minimize the elutriation loss of the iron ore. The apparatus includes a first fluidized bed furnace (110) for carrying out a first pre-reduction on only coarse/intermediate iron ore particles among fine iron ores of a wide particle size distribution by a bubbling/turbulent fluidization after their charge from a charging hopper (100), while making fine iron ore particles fly away. A second fluidized bed furnace (120) carries out a first pre-reduction on the fine iron ore particles flown from the first fluidized bed furnace (110) by a bubbling fluidization, and a third fluidized bed furnace (130) carries out a second pre-reduction on the iron ores discharged from the first (110) and second (120) fluidized bed furnaces after their first pre-reduction. A first cyclone (124) captures extremely fine iron ore particles from an off-gas discharged from the second fluidized bed furnace (120) to circulate them back to the second fluidized bed furnace (120). A  second cyclone (134) captures extremely fine iron ore particles from an off-gas discharged from the third fluidized bed furnace (130) to circulate them back to the third fluidized bed furnace (130). A gas reforming system (140) reforms a part of the off-gas of the first cyclone (124) to circulate the reformed gas to the first (110) and second (120) fluidized bed furnaces.

Title: Assessing lipid metabolism
Inventor: BARENDSE WILLIAM JOHN
IPC: C12Q1/68
Filed: 1998-10-23
Abstract: This invention relates to methods and nucleic acid probes for assessing characteristics of lipid metabolism in animals, and in particular to methods of predicting fat levels in meat, milk, or other fat depots of animals. Thus the invention provides a method of assessing the fat metabolism characteristics of an animal, comprising the step of testing the animal for the presence or absence of one or more markers selected from the group consisting of: a) an allele of the 5' untranslated region of the gene encoding thyroglobulin; b) an allele of the DNA polymorphism CSSM34, associated with the gene encoding retinoic acid receptor gamma (RARG); c) an allele of the DNA polymorphism ETH10, associated with 11-cis, 9-cis retinol dehydrogenase (RDH5). The invention is particularly applicable to predicting deposition of fat in muscular tissue, which produces the characteristic "marbling" of meat, and to assessment of milk fat content. The methods of the invention are useful in selection of animals, particularly cattle, for ability to produce or high levels of marbling in meat, and to produce high or low levels of milk fat content.
