Patent CA-2239304-C (CA)
Inventor: HOPPER HENRY E
IPC: G01F15/18
Filed: 1996-12-20
Granted: 2006-10-17
Abstract: An instrument installation system is provided which uses interchangeable hardware components and improved methods to connect differential pressure transducers to process piping. The system is designed to permit the instrument to be close coupled, direct mounted to the process connection or close coupled, support mounted using substantially the same system in both designs with simply the addition/subtraction of interchangeable components. Close coupling and very close coupling ensure that maximum accuracy in the measurement is possible. Pre-aligned root valve pairs and flange adapters pairs are provided, along with further adapters used when needed, to allow a rigid pipe, direct mounting of the transducer to the process connection without flange alignment problems. The installation system forces the rigid pipe impulse lines into a horizontal coplanar alignment with the centerlines of the high and low pressure ports of the differential transducer to minimize measurement errors of the kind associated with prior art remote mounted instrument installations.  An improved feature of the system over the prior art is also the elimination, if desired, of threaded connections in contact with the process fluid. The interchangeable hardware components are provided in different combinations that form instrument installation kits which provide substantial economies in design, procurement, installation, maintenance and servicing of process instrumentation.

Abstract: A packer is provided which reduces the number of components required in a retrievable packer. The packer is compact in size, and convenient and economical in use. In a described embodiment, the packer includes seal carrying and gripping assemblies mounted on a mandrel. Axial compression of the assemblies causes a seal and grip structures carried on the assemblies to radially outwardly deflect. Each of the assemblies may be integrally formed, thereby further reducing the number of components needed to construct the packer. Each of the assemblies is usable separately on the mandrel to produce apparatus which only grippingly engage or only sealingly engage a tubular member in a well. The packer or similar apparatus is retrieved by releasing the force axially compressing the assemblies.

Title: A method and a system for deicing of airfoil wings of composite material
Inventor: GRABAU PETER
IPC: F03D80/40
Filed: 1997-07-03
Granted: 2006-01-03
Abstract: For avoiding icing of windmill wings of composite materials, use is made of microwave energy for heating of the composite material itself, this energy preferably being supplied from interior, fixedly mounted microwave generators in response to detection of potential climatic conditions for icing to occur. The wing surface can be coated with a layer reflecting the microwaves, whereby these may propagate by reflections through and between the shell parts of which the wing will normally consist. It is possible to arrange for selective heating by the use of more generators, which may then, each, be of the type that is already in production with modest size and at low costs for use in ordinary microwave ovens.

Filed: 1999-03-04
Granted: 2009-09-22
Abstract: The operation of multistage catalytic hydrocarbon conversion system in which hydrocarbons flow serially through at least two reaction zones is improved by using staggered by-passing of a portion of the change to each zone such that the first zone processes only a first portion of the feed and the second zone processes the remaining portion of the feed and at least a portion of the effluent from the first zone. Where three reaction zones are used, processing of the effluent stream from the first reaction zone is split between the second and third reaction zones so that a portion of the charge to each zone always is directed around the zone and processed in the next reaction zone. One portion of the effluent stream is combined with hydrocarbons that bypassed the first reaction zone, and the combined stream is passed to the second reaction zone. The other portion of the first reaction zone effluent stream and at least a portion of the effluent stream of the second reaction zone are passed to the third reaction zone. This invention is applicable to processes where the first and second reaction zones are susceptible to pinning in that this invention decreases the mass flow through the first and second reaction zones while nevertheless maintaining high hydrocarbon conversion capacity.

Title: Well reference apparatus and method
Inventor: XU WEI
IPC: E21B47/04
Filed: 2000-05-18
Granted: 2008-04-01
Abstract: The well reference apparatus and method of the present invention includes a reference member preferably permanently installed within the borehole at a preferred depth and orientation in one trip into the well. The reference member provides a permanent reference for the location of all operations, particularly in a multi-lateral well. The assembly of the present invention includes disposing the reference member on the end of a pipe string. An orienting tool such as an MWD collar is disposed in the pipe string above the reference member. This assembly is lowered into the borehole on the pipe string. Once the preferred depth is attained, the MWD is activated to determine the orientation of the reference member. If the reference member is not oriented in the preferred direction, the pipe string is rotated to align the reference member in the preferred direction. This process is repeated for further corrective action and to verify the proper orientation of the reference member. Upon achieving the proper orientation of the reference member, the reference member is set within the borehole and the pipe string is disconnected from the reference member and retrieved.
