Patent CA-2337976-C (CA)
Inventor: WAWRZYNOWSKI MICHAEL
IPC: F16D11/04
Filed: 2001-02-23
Granted: 2008-12-02
Abstract: A pump rod drive and torque release mechanism for use in association with a downhole pump positioned within a well. The pump rod drive and torque release mechanism comprises a central housing having a generally hollow interior, a drive shaft received within the central housing, a drive rod received within the central housing, and a torque transfer mechanism positioned within the central housing. The drive shaft may be operatively connected to a pump rod rotator to impart rotational movement to the drive shaft. The drive rod may be operatively connected to a downhole pump so as to enable transference of rotational energy from the drive rod to the downhole pump. The torque transfer mechanism has an engaged position wherein it operatively connects the drive shaft to the drive rod such that rotation of the drive shaft causes rotation of the drive rod. The torque transfer mechanism also has a disengaged position wherein it operatively disconnects the drive shaft from the drive rod. When it is in its disengaged position, the torque transfer mechanism permits rotation of the drive rod relative to the drive shaft and a release of torque exerted on the drive rod by fluid present in the well above and bearing against the downhole pump.

Patent CA-2344180-C (CA)
Inventor: SMITH KEN
IPC: B01J23/28
Filed: 1999-09-17
Granted: 2008-04-29
Abstract: Single-walled carbon nanotubes have been synthesized by the catalytic decompo-sition of both carbon monoxide and ethylene over a supported metal catalyst know to produce larger multi-walled nanotubes. Under certain conditions, there is no termination of nanotube growth, and production appears to be limited only by the diffusion of reactant gas through the product nanotube mat that covers the catalyst. The present invention concerns a catalyst-substrate system which promotes the growth of nanotubes that are predominantly single-walled tubes in a specific size range, rather than the large irregular-sized multi-walled carbon fibrils that are known to grow from supported catalysts.  With development of the supported catalyst system to provide an effective means for production of single-wall nanotubes, and further development of the catalyst geometry to overcome the diffusion limitation, the present invention will allow bulk catalytic production of predominantly single-wall carbon nanotubes from metal catalysts located on a catalyst supporting surface.

Title: Canoe and kayak mid-point sponsons safety
Inventor: INGRAM ROBERT TIMOTHY
IPC: B63B43/14
Filed: 2002-01-14
Granted: 2003-11-25
Abstract: Canoe and kayak mid-point sponsors attach to the canoe or kayak only at the mid-point of the sponsors, to enable the sponsors to rotate around the midpoint in order to reduce drag in waves and simplify attachment and detachment to the canoe or kayak. They create greater sponsor buoyancy and stability than any other type of sponsor, without interfering with normal paddling to safety. They are attached to any canoe or kayak by material such as only one adjustable strap and two clips, extending to kayak deck fittings adjacent the cockpit or a canoe middle thwart, in such a manner as to facilitate normal paddling of the stabilized craft in life threatening emergencies. They can be directly attached to both sides of the hull near the waterline. The mid-point sponsors can be solid buoyant material, waterproof and airtight stowage bags containing bulky lightweight items such as sleeping bags, orally inflatable sponsor floats, and gas cartridge inflatable sponsor floats. A  particular feature is permanent or semi-permanent attachment to the hull above the waterline to eliminate drag unless inflated, in which case the inflated sponsors are forced to immerse in the water. When not inflated each midpoint sponsor is neatly stowed in a small and rescue-emergency marked stowage bag or covering that holds sponsors upward from the waterline. Such an arrangement ensures that the sponsors rest sleekly and unobtrusively along the hull side when not deployed.

Granted: 2006-10-03
Abstract: An intelligent fluid delivery system and method for controlling fluid delivery and monitoring parameters of fluid usage in a fluid jet printing system. The intelligent fluid delivery system (IFDS) includes the controls and electronic of the base station and fluid bottle. The replaceable base station, or nest, includes a micro-controller, independent of the main controller of the main printing system, for controlling fluid delivery and fluid management. The intelligent fluid delivery system provides a detection mechanism so that it can be ascertained with near certainty that an inserted fluid bottle is an appropriate fluid bottle having a fluid media that is compatible with the fluid jet printing system (e.g., within the specifications of the printing system and suitable for use with the other components of the ink jet printing system). The micro-controller of the intelligent fluid delivery system may be programmed to record and store information relating to the fluid bottle and the fluid media that may be useful when servicing the printing system. The intelligent fluid delivery system also improves the reliability of fluid delivery and fluid management, and hence, the overall performance of the fluid jet printing system by preventing/reducing the use of unknown or non-compatible fluid media. The intelligent fluid delivery system provides an improved fluid delivery system with controlled metering of fluid media, recording capability for the fluid delivery function(s), wireless communication of information between the base station and the fluid bottle, and can also provide communication of status and other information between the base station micro-controller and the main printing system (e.g., OEM  provided) controller.

Abstract: The invention relates to a screw connection comprising a seal ring (1), a connecting piece (10), and a union nut (11) for joining pipes, whereby the seal ring is designed as a cutting ring having one or more cutting edges (2, 3). Said cutting ring can be inserted into a boring of the connecting piece, said boring conically exitin g a face, by screwing the union nut onto the connecting piece, and the exterior of the se al ring is provided with a ring reinforcement on the side of the nut. Said ring reinforcement forms a ring surface on the transition thereof to the narrow ring part. The ring surface produced by the reinforcing part of the cutting ring is provided with a slope to the pip e axis that ranges from 45 .degree..degree. to 90 .degree..degree.. When fully assembled, the axial length of the ring reinforcement is such that the transfer elements placed on the ring surface transfer their negativ e image or themselves onto the face of the connecting piece. The transfer elements have three-dimensionally shaped contours whose negative image can be transferred to the face of the connecting piece. In a manner similar to a die, the negative image is presse d into the face of the connecting piece by the pressing force exerted by the assembler.

Title: Color separation method and printed product of the method
Inventor: LEE DAVID L
IPC: H04N1/58
Filed: 2003-01-07
Granted: 2011-08-16
Abstract: A method is described for overcoming the adverse visual effect of misregistered ink planes in multiple ink color prints. Color separations are initially made in a normal fashion. The separation carrying the greatest object detail is then chosen as a luminance or achromatic channel. This may be used as is or preferably it is sharpened using a high pass filter. Normally this separation will be black. However, it may be a surrogate color for black, particularly if only two or three separations are made. Object detail in all other separations (chrominance separations) is degraded, usually by a low pass filter such as a Gaussian blur. The printed image formed when the separations are recombined in a conventional manner is remarkably visually tolerant of misregistration of the various ink planes in the image.
