Patent CA-2162169-A1 (CA)
Title: Dent sur laquelle est applique un materiau resistant a l'abrasion
Inventor: CORNELIUS GREGORY S
IPC: E02F9/28
Filed: 1995-04-07
Abstract: Des dents sont généralement montées sur le bord d'attaque d'un outil de terrassement, tel qu'un godet, afin de faciliter la pénétration de celui-ci dans le matériau à exploiter. De plus, un matériau dur a été appliqué sur des surfaces sélectionnées des dents afin d'augmenter leur durée de vie. Toutefois, dans de nombreuses applications, le matériau dur est placé sur la surface des dents et est soumis à des chocs, ce qui provoque son élimination prématurée. Une dent symétrique (10), ménagée dans le dispositif en question, possède une languette surélevée (26, 44) dans ses parties supérieure et inférieure, chacune d'elles étant pourvue d'une rainure (30, 46) remplie d'un matériau résistant à l'abrasion (32, 48). Etant donné que les flancs de la dent (10) bordant chaque côté des languettes surélevées (26, 44) sont plus minces, ils s'useront à une plus grande vitesse que les languettes surélevées (26, 44) possédant le matériau résistant à l'abrasion placé dans leurs rainures respectives (30, 46). En conséquence, la languette surélevée augmente la résistance de la dent (10), le matériau résistant à l'abrasion placé dans les rainures (30, 46) de la languette surélevée (26, 44) augmente sa durée de vie et renforce l'acuité de son tranchant durant sa vie utile puisque les flancs de la dent s'usent plus rapidement.

Patent CA-2167495-A1 (CA)
Title: Ruminant feedstuffs and their production
Inventor: RUDDEN CONOR
IPC: A23K1/16
Filed: 1993-07-16
Abstract: A ruminant feedstuff comprises, in admixture, one or more edible, water-insoluble calcium or magnesium fatty acid salts and animal or vegetable protein nutritional material, the protein material having been converted during formation of the fatty ac-id salt into a form which is substantially non-degradable in the rumen but which is digestible in the lower gut. This feedstuff may be obtained by forming a substantially homogeneous mixture of animal or vegetable protein nutritional material, one or more fat-ty acids, suitably in liquid form, and a calcium or magnesium compound capable of forming an edible water-insoluble salt with the fatty acid under the conditions employed, initiating reaction of the fatty acid(s) and calcium or magnesium compound, suit-ably by raising the temperature of the ingredients e.g. by injection of steam into the substantially homogeneous mixture formed, maintaining the mixture at elevated temperature, e.g. 110 to 115°C, and then cooling the product. The process has the further ad-vantage that any mycotoxins present in the nutritional material are substantially detoxified by the combined action of the high temperature and the fatty acid and base, e.g. calcium oxide, preferably used.

Inventor: MICHELI PAUL L
IPC: H01M8/12
Filed: 1996-10-17
Abstract: A fuel cell and gas turbine combined cycle system which includes dual fuel cell cycles combined with a gas turbine cycle wherein a solid oxide fuel cell cycle operated at a pressure of between 6 to 15 atms tops the turbine cycle and is used to produce CO2 for a molten carbonate fuel cell cycle which bottoms the turbine and is operated at essentially atmospheric pressure.          A high pressure combustor is used to combust the excess fuel from the topping fuel cell cycle to further heat the pressurized gas driving the turbine. A low pressure combustor is used to combust the excess fuel from the bottoming fuel cell to reheat the gas stream passing out of the turbine which is used to preheat the pressurized air stream entering the topping fuel cell before passing into the bottoming fuel cell cathode.  The CO2 generated in the solid oxide fuel cell cycle cascades through the system to the molten carbonate fuel cell cycle cathode.

Patent CA-2192058-A1 (CA)
Title: Vital Wheel Detector
Inventor: BALLINGER FORREST H
IPC: B61L1/16
Filed: 1996-12-04
Abstract: A vital wheel detector for railways injects an oscillating electrical current into a short rail segment and produces a monitor signal in response the magnetic field around the rail. A high Q pickup coil is employed which, when a car wheel is present on the rail segment, sharply decreases in Q and significantly reduces the level of the monitor signal. Any failure of the detector apparatus is in a safe mode, as a loss of rail current results in a loss of the monitor signal whether through an electrical or a mechanical failure. Also, internal mechanical or electrical failures either interrupt the current to the rail or interrupt transmission of the monitor signal to the processing logic.
