Title: System for facilitating pathological examination of a lesion in tissue
Inventor: ZAVISLAN JAMES M
IPC: G06F19/00
Filed: 1998-02-19
Granted: 2010-01-05
Abstract: In order to facilitate pathological examination of a lesion (23a) in in vivo tissue, a system and method are provided having a computer system in which both a camera (19) for producing a digital macroscopic picture of the lesion, and an image (22) are coupled to the computer system. The image is responsive to the computer system and has optics for scanning the lesion to generate images representing microscopic sections of the lesion, which provide sufficient information for pathological examination of the lesion. The computer system generates location information, referencing the location in the microscopic picture of the lesion where the lesion was scanned to the images, and stores data in an electronic file structure which contains at least a macroscopic picture, and the location information.

Abstract: Partially deactivated catalyst in a slurry hydrocarbon synthesis process is rejuvenated employing a cyclic rejuvenation process in which syngas or CO flow into the slurry is stopped to stop the hydrocarbon synthesis reaction, the CO purged out of the slurry with a purge gas in the presence of hydrogen, the catalyst rejuvenated with a hydrogen containing rejuvenating gas and the hydrocarbon synthesis reaction restarted by passing the synthesis gas feed back into the reactor.  All or a portion of the purge gas and/or the rejuvenating gas may be recycled during the respective purge and/or rejuvenation. The hydrogen required during the purge is typically part of the purge gas.

Title: Retractable boat line
Inventor: KNIGHT DARREL C
IPC: B65H75/42
Filed: 1999-10-06
Granted: 2001-12-25
Abstract: A retractable boat line for mooring a boat is wound about a payoff reel contained within a stationary housing, which my be mounted beneath the exterior surfaces of the boat, for example within the hull, transom or gunnel. The invention provides a locking mechanism that latches into a guide wall of the payoff reel at a point remote from the edges of the guide wall to rotationally lock the payoff reel relative to the housing. The mooring line can thus be selectively extended to a desired length and remains locked to the selected length until the locking mechanism is disengaged.

Granted: 2009-03-03
Abstract: A pulley tensioner (10) for applying torque or tension to a pulley (14) is disclosed which includes a spring system (16) configured to at least partially encircle the periphery (18) of the pulley (14). The spring system (16) is anchored to the pulley housing (12) or some other fixed location. The spring system (16) is made up of one or more coil springs (28, 30, 32) which are wrapped at least partially around the periphery (18) of the pulley (14). Where multiple springs are used, preferably each spring has a different spring constant and length. This allows the operator to select the desired tension depending on the operating parameters of the printer (40). The applied tension may be further modified/tuned by using an additional spring member to anchor the spring system (16) to the pulley housing (12) or some other fixed location.

Abstract: It has been discovered that ammonia and amines are useful to increase the pH and corrosion resistance of high density brines, such as zinc bromide brines, without significantly reducing their densities. The ammonia or amine additive is preferably incorporated by contacting the brine with the additive which is in the vapor phase. Optionally, a substituted carboxylic acid, such as hydroxy carboxylic acid, may be used to increase the amount of ammonia or amine that can be included in the high density brine without precipitation of salts.

Title: Enhancement of antibody-cytokine fusion protein mediated immune responses by co-administration with angiogenesis inhibitor
Inventor: GILLIES STEPHEN D
IPC: A61K39/395
Filed: 1999-04-15
Granted: 2009-10-06
Abstract: Disclosed are compositions and methods for enhancing a cytocidal immune response directed against a preselected cell-type in a mammal. The methods and compositions rely on a combination of an antibody-cytokine immunoconjugate and an angiogenesis inhibitor.  Once administered to the mammal, the immunoconjugate induces an immune response against the preselected cell-type, for example, a cancer cell which, as a result of the synergy with the angiogenesis inhibitor, is greater than the immune response induced by the immunoconjugate alone. The methods and compositions are particularly useful at killing solid tumors or virally-infected cells in a mammal.
