Abstract: An elongate cultivating tool adapted to be supported at each end so as to be able in use to rotate about a longitudinal axis.    The cultivating tool comprises an elongate cylindrical support (1) which may be a helical coil spring, a plurality of cultivating elements (2) on a peripheral cylindrical surface of the cylindrical support, each cultivating element linking up with four other like cultivating elements on the peripheral cylindrical surface and one and preferably two tines (3) extending from each cultivating element. There may be two banks of cultivating elements on the tool to give a greater number of tines on the tool. The axle (6) to support the cylindrical support for rotation may be telescopic to provide tension to maintain the position of the cultivating elements. The cultivating elements are formed from metal rod and in one form comprise a U-shaped body with each leg of the U-shaped body including a bend out of the play of the body with each portion beyond the bend comprising a tine. In another form the elements comprise a circular loop portion, two tangential legs extending from the loop portion and crossing each other and each leg including a bend out of the plane of the loop portion beyond the crossing with each portion of the leg beyond the bend comprising the tine.

Patent CA-2175942-A1 (CA)
Inventor: RUSSELL EDGAR E
IPC: H04N5/365
Filed: 1996-05-07
Abstract: A responsivity calibration system for use with an array of detectors. The invention includes a first mechanism for changing the orientation of the detector array from the first orientation, during an operational mode, to a second orientation, during a calibration mode, in which each detector sequentially samples the same portion of the same scene. The inventive system adjusts the output generated by each of the detectors in the first orientation in response to an associated signal generated by that respective detector in the second orientation. In a specific implementation, a normalization factor is generated based on the output of each detector during said calibration mode. The normalization factor is stored and multiplied by the outputs of the detectors during the operational mode. Hence responsivity correction is implemented without the need for either a wide area scene of extreme uniformity or an on-board target.

Title: Improvements in metallurgical conversion
Inventor: DOROFEEV GENRIKH ALEXEEVICH
IPC: C21B5/00
Filed: 1995-02-23
Abstract: Improvements in metallurgical conversion in accordance with the present invention consist in the preparation of a semifinished item (a charge stock) in the form of a pig by forming thereof in a molding box of a casting machine from a solid filler, for the most part an oxidizing agent, and a liquid pig iron followed by cooling, provided said solid filler and said liquid pig iron undergo, in the process of forming, an action which prevents the floating up of the solid filler in the liquid pig iron.  Such an action is effected both by applying a mechanical force, in particular by providing a casting machine with a cantilever (8) having a hollow roller (9) which rests on a molding box (2) and a weighting material (10), and by choosing relative dimensions of the solid filler pieces and selecting a rate of pig casting.  Optimal conditions for using such semifinished item for metallurgical conversion which in accordance with the present invention is carried out in oxygen converters and are furnaces are described.
Patent CA-2183414-A1 (CA)
Inventor: DI LULLO ARIAS GINO F
IPC: C09K8/46
Filed: 1996-08-15
Abstract: A method of cementing an oil and gas wellbore is accomplished by mixing togetherblast furnace slag, construction grade cement and water to form a pumpable slurry. The slurry is then pumped to a selected location within an oil and gas well and allowed to solidify within the wellbore. The blast furnace slag alters the properties of the construction grade cement so that it can be used in the construction of oil and gas wells, where it would otherwise not be feasible to use. The blast furnace slag enhances the physical and chemical properties of the construction grade cement, increasing gel times and decreasing fluid loss.

Patent CA-2190385-A1 (CA)
Inventor: BOSS ANDRE
IPC: F42C9/00
Filed: 1996-11-14
Abstract: It is possible to improve the hit probability of programmable projectiles by means of this method. For this purpose a predetermined optimal disaggregation distance (Dz) between a disaggregation point (Pz) of the projectile (18) and an impact point (Pf) on the target is maintained constant by the correction of the disaggregation time (Tz) of the projectile (18). The correction is performed by adding a correcting factor, which is multiplied by a velocity difference, to the disaggregation time (Tz). The velocity difference is formed from the difference between the actually measured projectile velocity and a lead velocity of the projectile, wherein the lead velocity is calculated from the average value of a number of previous successive projectile velocities.

Patent CA-2195096-A1 (CA)
Title: Method of controlling production of excess water in oil and gas wells
Inventor: DAWSON JEFFREY CARL
IPC: C09K8/512
Filed: 1995-07-07
Abstract: The production of excessive water in oil and gas wells and other subterranean formations is reduced by introducing a hydrocarbon fluid containing dispersed superabsorbing particles formed using invert emulsion polymerization techniques wherein the superabsorbing particles are formed from hydratable polymers which are cross-linked so that they are insoluble in water. By introducing these superabsorbing particles into fluid passages of the formation, the water producing zones can be selectively blocked off by allowing the superabsorbing particles to swell with the absorption of water within the aqueous fluid containing fluid passages, while the superabsorbing particles remain small and unswollen in the hydrocarbon conducting fluid passages. Thus, the ability of fluids to flow through the aqueous fluid containing fluid passages is selectively reduced resulting in the reduced production of aqueous fluids while maintaining production of hydrocarbons.

Le projet présenté innove en apportant un procédé permettant d'atteindre ces deu x objectifs, soit rejoindre la masse sociale, et ce, de façon personnelle. L'innovation du procédé consiste à surveiller les voies routières avec des équip ements vidéos performants, doublés de radars et d'ordinateurs. Par la suite, chaque infraction au code de l a sécurité routière peut être recencé et pour chacune d'elle, une lettre d'avertissement personnalisée est émise au co ntrevenant.
