Title: Perfusion catheter
Inventor: HIRAYAMA HARUO
IPC: A61M25/10
Filed: 1996-08-30
Abstract: A  perfusion  catheter having an  improved  fluidity  of blood  in  a blood passage and an improved operability  in  a blood  vessel.   The perfusion catheter is provided  with  an outer  tube  inserted  through a balloon and  an  inner  tube having  a tapered or pointed tip disposed in the outer  tube.

Title: Low friction packing
Inventor: LOVELL MICHEL K
IPC: F16J15/24
Filed: 1995-02-09
Abstract: A two-part, low friction, live loaded packing system for fire safety and low fugitive emission sealing (less than 500 ppm) of a valve stem at operating temperatures up to 450°F (232°C).  One lower packing ring set around the valve stem has PTFE washers sandwiched between flexible graphite rings to provide fire safety and low friction.  An upper packing ring set around the valve stem is closer to the loading source and has V-type PTFE rings to provide reliable low fugitive emission sealing and low friction.  The live loading is optimized to maintain a seal at the upper packing set to less than 500 ppm leakage, minimize packing friction from both the upper and lower packing sets, and seal the lower packing set during fire safety tests.

Title: System for determining motor position in a biomedical device
Inventor: HOLDAWAY CHARLES R
IPC: A61M5/00
Filed: 1995-09-11
Abstract: A drive member of a peristaltic pumping mechanism includes a disk (24) that rotates with the drive member (18) and has two transparent sectors (27, 26) and two opaque sectors (28, 29) alternating with the transparent sectors.

Title: Method and apparatus for image plane modulation pattern recognition
Inventor: LEE SHIH-JONG J
IPC: G06T7/60
Filed: 1995-09-13
Abstract: The detection of optical stripes on an image of a glass slide (20) of material of interest. An automated microscope system (511) with an illuminator (508) having a spatial intensity homogenizer (40) provides spatially uniform illumination of a microscope slide specimen (20). Periodic optical patterns formed from the illumination system (508) are detected by a computer system (540). The computer (540) forms a high transmission mask (717) of an image (712) of the biological specimen (20). Edges in the image are detected (716) and a low transmission area process (718) is performed. Horizontal stripes are enhanced (720). A final thresholding (722) generates a binary image (727) of the patterns. Stripes in the patterns are detected (724) and a stripe flag (706) and stripe area (708) are calculated.

Abstract: An axle measurement holder device to fasten a measuring head to the rim (5) of a vehicle wheel (2), includes a base body (3) for direct or indirect stable contact with a rim (5) of a vehicle wheel (2). Two arms (13,14) arranged diametrically opposed feature respective hooks (15,16) at their ends that are directed radially outward to hook into a tread of a tire (17). The ends of the arms (13,14) directed radially toward the inside are attached by means of a pivot bearing (11,12) to the end of a one armed lever (13,14), the end of which is directed away from the base body (3), the other end of which is connected to the base body (3) via an articulation (20,21) and tension springs (22,23). The one armed levers (7,8) canbe tensed radially inward by means of clamping devices. The one armed levers (7,8) are each preloaded radially toward the outside by centering springs (33,34) which exert the same force and have the same characteristics and which are supported at a central point of the base body (3). The centering springs (33,34)hold the arms (13,14) and thereby the hooks (15,16) located at their ends in anytensed position at the same radial distance to the axle that is defined by the axle shaft (6). This simplifies the attachment and clamping of the axle measurement holder device.

Patent CA-2215777-A1 (CA)
Inventor: DOSHI KISHORE J
IPC: B01D53/22
Filed: 1997-09-18
Abstract: A process is disclosed for the shut-down of a membrane separation zone comprising a non-permeate side and a permeate side and processing a feed stream comprising a non-permeable component, a less-readily permeable, condensible component, and a readily permeable component. When the feed stream is not passed to the membrane separation zone, a purge stream is passed at a relatively higher pressure to the non-permeate side of the membrane separation zone to remove a residual gas stream and thereby prevent condensation of the less-readily permeable, condensible component upon depressurization and/or cooling of the membrane separation zone. The invention reduces the need for oversizing membrane system which reduces treating costs and prevents permeate damage to membrane surfaces caused by condensation of less-readily permeable, condensible components such as C6+  hydrocarbons.

Patent CA-2218877-A1 (CA)
Inventor: POLLAK ALFRED
IPC: A61K51/08
Filed: 1996-05-16
Abstract: Compounds useful for high resolution diagnostic imaging incorporate an imaging agent having a chelator that is linked by a metal-cleavable bond to a ligand that has affinity for a site removed from the site of diagnostic interest. Upon labelling, the ligand is cleaved leaving the labelled imaging agent free to localize at the site of diagnostic interest unhindered, while the ligand and any unlabelled imaging agent is sequestered to the removed site. By sequestering unlabelled imaging agent, the labelled imaging agent does not compete to occupy the site of interest, resulting in images of enhanced resolution.
