Patent CA-2833008-A1 (CA)
Inventor: FIEBIG KEVIN M
IPC: A61B10/02
Filed: 2012-04-10
Abstract: A biopsy device comprises a needle, a body portion, and a needle firing assembly. The needle firing assembly is operable to fire the needle distally relative to the body portion. The needle firing assembly includes two translating members, a resilient member, and a motor. The motor is operable to selectively move the first translating member distally and proximally. The second translating member is secured relative to the needle such that the needle and the second translating member translate unitarily. The resilient member compresses as the first translating member is moved distally toward the second translating member. The first translating member is then secured to the second translating and the translating members are moved proximally while holding the resilient member in the compressed state. The second translating member is released from the first translating member when they reach a proximal position, which allows the resilient member to fire the needle distally.

Title: Improved heavy duty modular flooring and roadway device
Inventor: ROSAN ARNON
IPC: E01C5/00
Filed: 2012-04-19
Abstract: A modular flooring system is disclosed which is designed to support heavy loads while providing stability and ground protection. The invention contemplates a modular mat having an integral main body with offset mounting and assembly flanges and a lattice interior. The mat is constructed from a unitary piece of high strength plastic. Each flange edge contains an outward radiused edge, while each non- flange edge contains an inward radiused edge. Each flange engages with a corresponding flange on an adjacent tile, allowing the outward radiused and inward radiused edges to properly mate. One or more metal cam locks located along the upper flange edges are secured into corresponding cam receptacles located along the lower flange edge. The mats may utilize optional top covers to prevent water and debris from entering the mats. The modular flooring system provides increased strength and stability and protection of the subsurface in heavy industrial applications.

Title: Rotary steerable assembly inhibiting counterclockwise whirl during directional drilling
Inventor: LARRONDE MICHAEL L
IPC: E21B7/08
Filed: 2012-08-17
Abstract: A bottom hole assembly avoids damaging vibrations that can develop during directional drilling with a rotary steerable system. The assembly has a drill bit, a first collar that rotates with the bit, a rotary steerable tool that controls the bit's trajectory, and a second collar that rotates with the drill string. The first collar between the bit and the tool defines a bend that deflects the bit from the first collar's axis. During operation, this bend causes portion of the assembly to engage the borehole wall to inhibit counterclockwise (CCW) bit whirl by promoting clockwise whiri in the assembly, generating friction against the borehole wall, and dampening vibrations. By inhibiting CCW bit whirl, other damaging vibrations such as CCW whirl in the drill string can also be prevented up the borehole.

Patent CA-2851633-A1 (CA)
IPC: C04B35/46
Filed: 2014-05-12
Abstract: Thermal sprayed ceramic coatings are successfully employed to enhance the load carrying capacity and the tribological performance of the base material in order to extend the in-service life of equipment, including metal-seated ball valves (MSBV's) in Hydrometallurgy service. Ceramic coatings are vital to protect machines in the harsh abrasive conditions encountered in corrosive processes such as Pressure Oxidation (POx) and High Pressure Acid Leach (HPAL). Velan, a leading designer and manufacturer of industrial valves, has 20 years of experience in the engineering of severe service MSBV's for critical isolation applications around the autoclave. The National Research Council of Canada (NRC) in Boucherville and Polytechnique Montreal have world recognized know-how on coating engineering and characterization, in particular for wear. A detailed characterization project was undertaken by Velan in collaboration with the NRC and Polytechnique Montreal to perform mechanical and tribological resistance evaluation of the most promising ceramic coatings potentially suitable for this service, including a novel blend of n-Ti02-Cr2O3. Hardness and shear strength were evaluated using micro-hardness indentation testers and universal tensile testing equipment. Wear resistance of the coatings under different conditions such as sliding wear, abrasion and galling were measured by standard pin-on-disc tests, abrasion tests and custom-design galling tests. It was found that TiO2-Cr2O3 offers superior tribological performances compared to n-TiO2, mainly due to the presence of Cr2O3. Optimized balance between the hard and brittle Cr2O3 phases and the soft and ductile TiO2 phases yields to higher abrasion, sliding and galling resistance. In parallel, the novel mix of n-TiO, and Cr2O3 is considered as a promising evolution of the current TiO2-Cr2O3 blend.
