Patent number: 8794941Abstract: A positive displacement compressor designed for near isothermal compression. A rotor includes a curved sealing portion that coincides with a in an interior rotor casing wall. Liquid injectors provide cooling liquid. A gate moves within the compression chamber to either make contact with or be proximate to the rotor as it turns. Gate positioning systems position the gate in this manner, taking into account the shape of the rotor. Outlet valves allow for expulsion of liquids and compressed gas. The unique geometry and relationship between the parts provides for efficiencies and higher pressures not previously found in existing compressor designs.Type: GrantFiled: August 29, 2011Date of Patent: August 5, 2014Assignee: Oscomp Systems Inc.Inventors: Pedro Santos, Jeremy Pitts, Andrew Nelson, Johannes Santen, John Walton, Mitchell Westwood, Harrison O'Hanley

Patent number: 8570223Abstract: A micro electromechanical (MEMS) antenna (36) is positioned on one side of a substrate and is connected to a MEMS switch comprising a capacitor bridge (46) and to a transmission line (42) by means of a thru hole or via (48) which forms an electrically conducting path through the substrate. This arrangement provides a common ground plane for the antenna and switch and shields the switch from the electromagnetic radiation received or transmitted from the antenna. The switch may comprise a topmost metal layer which extends across a bridge structure formed by a polymer layer (19). The polymer layer comprises poly-monochloro-para-xylene (parylene-C). Homogeneous or heterogeneous antenna array structures are implemented. The antenna arrays may include one or more different type of antennas with for example different shapes, rotations and reflections.Type: GrantFiled: June 13, 2008Date of Patent: October 29, 2013Assignee: The University Court of the University of EdinburghInventors: Tughrul Arslan, Anthony John Walton, Nakul R.

Patent number: 7360611Abstract: A strainer system having two separate strainers positioned in parallel, where one strainer can be cleaned while still permitting normal flow through the other strainer. The system flow circuit is arranged so that a high pressure backwashing flow can be applied to one strainer while the other strainer is providing its normal straining function. The backwashed strainer is then isolated by valves so that its access flange can be removed and the particulate buildup within the valve plug cleaned out. The strainer is then returned to service following the replacement of the access flange. In this manner, it is possible to alternate between the two strainers so that continuous flow can be maintained to the hydraulic choke located downstream of the strainer system.Type: GrantFiled: May 23, 2007Date of Patent: April 22, 2008Assignee: Expro Americas, L.P.Inventors: Donald Glynn Sims, Michael James Taylor, Robert Frank Schmidt, David Anthony Schmidt, John Walton McCaskill

Patent number: 7275606Abstract: The invention contemplates a strainer based upon a four-way, two-position rotary cylindrical plug valve having a hollow plug. The normal entry port for the sealing plug of the plug valve is a circular radial hole passing from the exterior of the plug into the interior cavity of the plug. The normal exit port for the sealing plug is a regular array of small holes across from and coaxial with the normal entry hole. The ports for the valve body are in two pairs positioned at 90° from each other, with the axes of the ports lying in the same transverse plane as the ports of the valve plug.Type: GrantFiled: May 4, 2007Date of Patent: October 2, 2007Assignee: Expro Americas, L.P.Inventors: Donald Glynn Sims, Michael James Sims, Robert Frank Schmidt, David Anthony Schmidt, John Walton McCaskill
