Patent CA-2857016-A1 (CA)
Inventor: HANNAPPEL ULRICH
IPC: C07K1/14
Filed: 2012-11-28
Abstract: The invention broadly relates to methods of fragmenting seed by use of mechanical devices such as crushing pins or other crushing devices with a preconditioned hard seed. Methods of preconditioning the seeds to soften the seed for more effective fragmentation which are adapted to enhance extracted DNA yields and/ or DNA quality are shown. Extracted DNA yield from alkali-soaked seeds can be significantly increased by adding an osmoticum to a seed-softening alkali soaking solution used for pretreatment of the seeds prior to crushing them. The osmoticum inhibits and reduces liquid uptake by the seeds, but the seeds are weakened enough to be crushed with steel beads, without requiring the use of crushing pins or other crushing devices.

IPC: G01S17/08
Filed: 2010-08-31
Abstract: Techniques that optimize performance of simultaneous localization and mapping (SLAM) processes for mobile devices, typically a mobile robot. In one embodiment, erroneous particles are introduced to the particle filtering process of localization. Monitoring the weights of the erroneous particles relative to the particles maintained for SLAM provides a verification that the robot is localized and detection that it is no longer localized. In another embodiment, cell-based grid mapping of a mobile robot's environment also monitors cells for changes in their probability of occupancy. Cells with a changing occupancy probability are marked as dynamic and updating of such cells to the map is suspended or modified until their individual occupancy probabilities have stabilized. In another embodiment, mapping is suspended when it is determined that the device is acquiring data regarding its physical environment in such a way that use of the data for mapping will incorporate distortions into the map, as for example when the robotic device is tilted.

Patent CA-2892390-A1 (CA)
Inventor: WYLLE IAN W
IPC: C02F11/147
Filed: 2015-06-25
Abstract: The invention described herein is a method of treating sludges or other wastes containing organic compounds to generate biogas and to recover useful products from those wastes including sulfur compounds. The Kraft pulp process which utilizes sulfide ions (S2-) as a feedstock to strengthen paper through lignin or other non-cellulose material removal is a particular but non-exclusive application for this invention. The generation of biogas from forestry product wastes is indicated in part because of the large concentration of carbon-compounds in the waste which produces a high yield of biogas containing methane, carbon dioxide, and hydrogen sulfide. The hydrogen sulfide in the biogas is undesirable because of its toxicity and the regulatory barriers to its presence and use in natural gas streams.  Preferential removal of the hydrogen sulfide (H2S) Is performed with a gas-liquid Interaction (scrubber) of the biogas with an alkaline solution, preferably containing caustic (NaoH). The configuration and parameters of the scrubber is described herein, Optionally, the capture of H2S Is performed with a "white liquor" solution from a Kraft pulp and paper process and optionally recycled for further use In the Kraft paper process. Other Kraft process gases, such as methyl mercaptan (CH4S), can also be captured in an alkaline solution for similar purposes. An additional method of producing and treating biogas contaminated with sulfur compounds is described. This method describes a preferential treatment of the organic waste at a lower temperature (below 35°C) to enhance the production of these sulfur gases by sulfur reducing bacteria (SRB) followed by a higher temperature (above 35°C) methanogenic biogas formation step to produce Wages essentially free of reduced sulfur compounds. A method of capturing less water soluble reduced sulfur gases, such as dimethyl sulfide (C2H6S) and dimethyl disulfide (C2H6S2), using a solution containing methanol is also disclosed with an optional method of electrochemical treatment of the dissolved gases. Finally, the biogas process may also constitute one step of a combined treatment process for forestry product wastes which may include a step of recycling other nutrients for enhanced waste digestion including nitrogen and phosphorus.

Abstract: Un manchon coulissant s'ouvre avec un ballon déployé. Le manchon présente un siège disposé dans l'enveloppe et le siège possède des segments sollicités vers l'extérieur indépendamment par une bague en forme de C ou un autre élément de sollicitation. Initialement, le siège se trouve à l'état déployé dans le manchon coulissant de telle sorte que les segments des sièges se déploient vers l'extérieur contre l'alésage de l'enveloppe. Lorsqu'un ballon de taille appropriée est déployé en fond de trou, il vient contre le siège déployé. Une pression de fluide appliquée contre le ballon reposant sur son siège déplace le siège dans l'alésage du manchon interne. A ce moment-là, le siège se contracte, ce qui augmente la zone de contact du siège avec le ballon. Finalement, le siège atteint l'épaulement dans le manchon interne si bien que la pression appliquée contre le ballon sur son siège déplace le manchon interne dans l'enveloppe pour ouvrir l'orifice d'écoulement du manchon coulissant.
