Abstract: Biodegradable anionic polymers are disclosed which include recurring polymeric subunits preferably made up of vinylic and dicarboxylic monomers such as vinyl acetate or vinyl alcohol and maleic anhydride, itaconic anhydride or citraconic anhydride, or combinations thereof. Free radical polymerization is used in the synthesis of the polymers, which are then hydrolyzed to replace ester groups with alcohol groups. The polymers may be complexed with ions and/or mixed with fertilizers or seed to yield agriculturally useful compositions. The preferred products of the invention may be applied foliarly, to seeds, to fertilizer, or to the earth adjacent growing plants in order to enhance nutrient uptake by the plants.

Title: Motoneige a positionnement actif du conducteur
Inventor: GIROUARD BRUNO
IPC: B62D55/07
Filed: 2002-11-15
Granted: 2005-07-26
Abstract: Une motoneige a un cadre avec un tunnel, un siège de chevauchement, une chenille d'entraînement propulsée par un moteur, et deux skis. Un dispositif de direction se connecte pendant le fonctionnement à au moins un ski pour diriger la motoneige. Le dispositif de direction est placé de telle façon que lorsqu'un pilote standard se trouve dans une position standard sur le siège, ses genoux sont placés à l'avant de ses chevilles et au-dessous de ses hanches. Les genoux du pilote sont également placés suffisamment loin du dispositif de direction pour que les genoux du pilote n'interfèrent pas avec la direction de la motoneige. Ce positionnement du pilote permet au pilote d'absorber facilement les bosses et de se placer activement sur la motoneige.

Abstract: Apparatus for positioning a surgical instrument (4) during a surgical orthopaedic procedure relative to the coordinate system of the apparatus, comprises a surgical instrument and a robotic control system (6) for moving the surgical instrument within the apparatus coordinate system according to program instructions. An instrument sensor (12) is fixed relative to the instrument to indicate the true position of the instrument within the apparatus coordinate system, and a reference sensor (16) is then fixed to a patient's bone to indicate the position of the patient's bone within the apparatus coordinate system. A detector (14) for monitoring the positions of the instrument sensor and the reference sensor, and a signal processor receives position signals from the detector, and generates a desired position signal to the robotic control system to position the surgical instrument at a desired location relative to the reference sensor, by a process which involves minimising the difference between the true position of the instrument and the said desired location.

Patent CA-2415009-C (CA)

Granted: 2011-04-12
Abstract: L'invention porte sur une méthode d'impression en couleurs dans laquelle seulement deux encres transparentes sont utilisées pour reproduire une image source. L'image à codage numérique originale en rouge, en vert et en bleu peut être initialement réglée en fonction du contraste, de la luminosité, de l'équilibre chromatique et de la valeur d'une teinte. Elle est alors convertie en codage cyan, magenta et jaune. Les deux canaux qui représentent le mieux les couleurs dominantes de l'image originale sont alors sélectionnés. Les couleurs critiques de l'image originale à reproduire avec une précision raisonnable sont déterminées, et des couleurs d'appoint qui les représentent le mieux sont sélectionnées d'une palette d'encre. Les couleurs d'appoint sont assignées aux canaux sélectionnés auxquels elles ont la relation de couleur la plus proche. Ces deux canaux sont ensuite superposés pour former une image composite et leurs valeurs en échelle de gris sont réglées pour produire une image ressemblant le plus à l'image finale désirée. De nouvelles séparations positives sont ensuite faites et inversées aux images négatives à partir desquelles les plaques d'impression peuvent être préparées. Un troisième canal peut être introduit, se rapprochant de la couleur d'un substrat coloré avant le dernier réglage de l'échelle de gris. Toutefois, ce canal n'est pas imprimé.. Une procédure supplémentaire utile avec les substrats de couleur est de préparer un canal masqué qui déposera une encre opaque, normalement blanc, qui sera sous-jacent aux deux encres transparentes et qui aidera à contrôler la couleur du substrat. Dans le cas de cette mise en oeuvre, le troisième canal est imprimé. La méthode a la capacité de rendre les images en couleur très attrayantes sur les substrats comme le papier kraft écru utilisé pour les contenants d'expédition ondulés.

Title: Method for the production of a material for the promotion of plant growth based on clay and rock powder and product obtained therewith
Inventor: BAUMANN GERHARD
IPC: C05D9/00
Filed: 2002-04-19
Granted: 2010-09-14
Abstract: The invention relates to a ground material, obtained by grinding mineral materials. Said ground material is mixed with matured compost and/or sludge, obtained by the elutriation of mature compost and is matured under controlled conditions, in particular at a temperature limited to 60 °C, for several weeks or several months. During said maturing process, the mineral material decomposes and biological activation occurs by means of the micro-organisms (fungi etc.) that have formed during the activation phase. The product thus obtained has an improved action for promoting plant growth. In a preferred embodiment, a plant seed cultivation is carried out on the activated substrate, in particular a thin layer cultivation. The green matter that has been formed, in addition to the substrate with interspersed roots, can e.g. be ground to produce an enriched product. The advantages already offered by the activated product are demonstrated by the addition of the green matter that has formed to inactivated (41, 43, 46) and activated material (42, 44, 45).
