Patent CA-2896361-A1 (CA)
Title: Production of non-carcinogenic brightstock extracts
Inventor: SIRCAR CRISTINA M
IPC: C10G53/06
Filed: 2014-02-20
Abstract: Provided are multiple correlations for relationships between MI value for a brightstock extract and the distillation cut point temperature used for separation of the vacuum resid that is used to form the brightstock extract. Based on these correlations, a BSE having a desired MI value can be formed based on an adjustment of the distillation cut point temperature. A first correlation establishes a relationship between a fractional weight boiling temperature for a vacuum resid fraction and a distillation cut point temperature for separating the vacuum resid fraction from at least one distillate fraction in a feedstock. A second correlation establishes a relationship between a fractional weight boiling temperature for a brightstock extract derived from the vacuum resid fraction, and the fractional weight boiling temperature for the vacuum resid fraction. A third correlation has been established between the fractional weight boiling temperature for the brightstock extract and a mutagenicity index value.

Title: Sliding sleeve bypass valve for well treatment
Inventor: TILLEY DAVID J
IPC: E21B34/12
Filed: 2013-03-13
Abstract: A downhole bypass valve utilizes a stationary sleeve defining an interior ball-seat. When a dropped ball is seated, fluid differential pressure is diverted to an annular area adjacent a first sliding sleeve. The sleeve slides in response to the pressure differential upon shearing of a shear pin, or similar, and opens ports to the wellbore annulus. Treatment or maintenance operations can then occur through the ports, which can be fitted with nozzles. A second sliding sleeve, independent from the first, is operated in response to dropping a second ball into the device. The second ball diverts fluid differential pressure to an annular area adjacent the second sleeve and movement occurs when a shear pin shears. The second sleeve covers the ports to the wellbore annulus and closes the valve. After a sliding sleeve shifts, pressure across the sleeve is equalized, allowing reverse flow without risk of accidental sleeve actuation.

Patent CA-2911616-A1 (CA)
Inventor: DJURICA RADOSLAV
IPC: B60F3/00
Filed: 2015-11-09
Abstract: The invention is an integrated system for travel on water and land that requires no tools, with an option to use only the specific bicycle as any other conventional bicycle.  The integrated system consists of the specific bicycle and the water travel gear which itself consists of plurality of parts that are either assembled into water travel mode or land travel mode.  In the case when the specific bicycle is to be used as any other conventional bicycle, water travel gear is easily detached and stored as a compact unit. Therefore, the integrated system consists of the specific bicycle and water travel gear consisting of plurality of parts that are either assembled into water travel mode, or assembled into land travel mode. When in land travel mode, water travel gear can be easily detached and stored as a compact unit. In water travel mode, 3-piece-float front and rear assemblies are assembled into a flat shape, meaning side floats are parallel to the main floats, and then attached to the specific bicycle axles by the means of embedded respective brackets in said 3-piece-float front and rear assemblies. Two paddles are attached to the rear wheel, providing propulsion.  Balancer and rack lock are secured with the bicycle rack. In land travel mode, members of water travel gear are interconnected at the back of the specific bicycle. 3-piece-float front and rear assemblies are first assembled into a U shape, meaning side floats are perpendicular to the main floats, and then, along with their embedded respective brackets, stacked on the bicycle rack. Two paddles are attached to the bicycle rack at front and to the balancer at the back, with balancer itself connected to the side front floats.  The whole assembly is secured on the specific bicycle with the bicycle rack lock. Alternatively, the specific bicycle can be used as any other bicycle. To do so, water travel gear can be easily detached from the specific bicycle as a single, compact unit and stored. That is, an user has to unscrew bicycle rack wing screw that connects it with the specific bicycle, as well as to unscrew rear wing nuts so the bicycle rack with all the other parts consisting the water travel gear can be taken off the specific bicycle. As the water travel gear that was previously assembled for the land travel mode on the said specific bicycle, the task is considerably easier.

Inventor: PHILLIPS MATTHEW THOMAS
IPC: H05K7/20
Filed: 2015-06-18
Abstract: An inverted exhaust plenum module exhausts air from an enclosure into an ambient environment while mitigating airflow restrictions caused by ambient wind conditions, particularly headwinds impinging on exhaust vents. The plenum module includes wall elements that extend downwards from separate edges of two separate roof elements of the enclosure, forming a plenum between the wall elements that is open at the top. Exhaust vents in the wall elements exhaust air from the enclosure into the plenum to circulate into the ambient environment via the top of the plenum. By exhausting air into a plenum that extends beneath roof elements, the vents are at least partially obscured from ambient winds that might otherwise impinge on the vents. A wing element can be installed to induce exhaust airflow via lowering air pressure at the top of the plenum. The plenum module can be a separate module that is coupled to a structure.
