Abstract: Compositions that are used in nucleic acid amplification in vitro are disclosed, which include a target specific universal (TSU) promoter primer or promoter provider oligonucleotide that includes a target specific (TS) sequence that hybridizes specifically to a target sequence that is amplified and a universal (U) sequence that is introduced into the sequence that is amplified, by using a primer for the universal sequence. Methods of nucleic acid amplification in vitro are disclosed that use one or more TSU oligonucleotides to attached a U sequence to a target nucleic acid in a target capture step and then use a primer for a U sequence in subsequent amplification steps performed in substantially isothermal conditions to make amplification products that contain a U sequence that indicates the presence of the target nucleic acid in a sample.

Title: Process and system for production of asphaltene by-product in paraffinic froth treatment operations
Inventor: STEVENS GEOFF
IPC: C10G1/04
Filed: 2009-10-20
Granted: 2016-08-09
Abstract: A process and system for treating bitumen froth with paraffinic solvent is provided which uses three stages of separation. Froth and a first solvent are directed to a first stage at a solvent/bitumen ratio for precipitating few or substantially no asphaltenes. A first stage underflow is directed to a second stage and a first stage overflow is directed to a third stage. A second stage underflow is directed to waste tailings and the second stage overflow joins the first stage overflow. A third stage underflow is recovered as an asphaltene by-product and a third stage overflow is recovered as a diluted bitumen product. At least a second solvent is added to one or both of the second or third stages for controlling a fraction of asphaltenes in the third stage underflow. Asphaltene loss to waste tailings is minimized and asphaltenes are now recovered as asphaltene by-product.

Granted: 2016-01-12
Abstract: In a front wheel drive vehicle a traditional twist beam axle suffers from a short service life due to premature failures in intermediate areas between the end sections and the transitional section. A  twist beam suspension is provided comprising a transverse strut (16) interconnecting longitudinal control arms (12). The transverse strut (16) may be formed from a tubular pipe. The tubular member may define a pair of tubular end sections (18), a deformed, U-shaped transitional section (20), and a pair of intermediate sections (22) between the end sections (18) and the transitional section (20).  The intermediate section (22) may define a contour (28), known as a tongue. The tongue (28) enhances the flexibility in torsion and improves the stiffness in bending of the transverse strut (16). The tongue (28) may also include a concavity, to further aid in improving stiffness.

Abstract: The invention relates to measuring devices to be used in the measuring of angular velocity and, more precisely, to vibrating micromechanical sensors of angular velocity. In a sensor of angular velocity according to the invention, a mass is supported to the frame of the sensor component by means of an asymmetrical spring structure (1), (2), (3), (4), (22), (24) in such a way, that the coupling from one mode of motion to another, conveyed by the spring (1), (2), (3), (4), (22), (24), cancels or alleviates the coupling caused by the non-ideality due to the skewness in the springs or in their support. The structure of the sensor of angular velocity according to the invention enables reliable measuring with good performance, particularly in small vibrating micromechanical so-lutions for sensors of angular velocity.
