Filed: 1994-04-06
Abstract: A guidewire (16) for guiding and exchang-ing body insertable catheters includes a body insertable guide section (18) and an exchange section (20), both formed of flexible wire. In one embodiment, a pin connector (28) at the dis-tal end of the exchange section (20) includes a truncated conical head (32), a shank (40), and a groove (44) between the head (32) and the shank (40). A socket connector (24) is attached to the proximal end of the guide section (18). Four indentations (58, 60, 62, 64) are formed in the socket connector (24), spaced apart angularly 90° from one another. The maximum diameter of the conical head (32) is greater than the dis-tance between opposed nodules (58, 60, 62, 64), but less than the inside diameter of the socket connector (24). Thus, the pin connector (28) is insertable into the socket connector (24) and temporarily elastically deforms the socket as the conical head (32) moves past the nodules (58, 60, 62, 64). Once the head (32) is beyond the nodules (58, 60, 62, 64), the nodules (58, 60, 62, 64) are captured within the groove (44), to allow rotation of the exchange section (20) rel-ative to the guide section (18) while preventing any substantial axial relative movement of the sections (18, 20). The exchange section (20) can be disconnected from the guide section (18) by withdrawing the pin connector (28) proximally, again elastically deforming the socket (24) as the head (32) passes the nodules (58, 60, 62, 64).

Title: A covered roll and a method for making the same
Inventor: PAASONEN JAN ANDERS
IPC: B32B3/02
Filed: 1996-04-04
Abstract: The problems caused by chemical and thermal shrinkage of hard roll covers, are reduced by the inclusion of one or more intermediate compressive layers between the metal roll substrate and the outer cover, or topstock.   A compressive layer has the properties of being rigid enough to allow the cover to be applied to the roll, and compressible enough to deform and absorb the stresses which occur as the cover is shrinking during processing.    In  one  embodiment,  the  intermediate  compressive  layer comprises a three dimensional fabric that is  filled preferably with a thermoset resin system which cures at lower temperature than cover.   In a second embodiment,  the precise amount of shrinkage in the roll is predetermined to a high enough degree of accuracy so that a depth for the fabric layer can be used to compensate for the amount of shrinkage, thereby eliminating the need for filling.  In a third embodiment, the compressive layer is comprised of a meltable material wherein said material melts at cure temperatures. The resulting cavity is then filled with a thermoset resin.  The resulting cavity is then filled with a thermoset resin.    The problems caused by chemical and thermal shrinkage are further reduced through a method based on applying a polymeric cover layer over one or more intermediate compressive layers, curing at an elevated temperature, and, allowing the cover to shrink during curing or hardening.

IPC: G01F1/7086
Filed: 1996-05-29
Abstract: A failsafe apparatus for verifying a volume of aspirated reagent before it is provided to dilute a sample in an automated assay instrument.  A pump draws reagent through a tube having a reagent probe disposed at one end.  An optical flow detector includes an optical source disposed proximate the tube to illuminate the interior of the tube, and a photodetector oriented ninety degrees about the circumference of the tube from the source to detect reflected illumination  from the  contents  of the tube.          The photodetector provides one voltage level with gas/air within the tube, and a second level with a liquid within the  tube.  A circuit in communication with the detector discriminates  between the two levels.  The rate at which aspirate is pumped and the volume of the tube from a probe tip inlet to the detector are known constants.  Therefore, a  given  volume of  aspirate  takes a predictable  amount of  time  to  pass from tip to detector.  The actual time is determined by measuring  the elapsed time between the start of the aspiration on of a reagent, and a liquid-air transition detected at the end of the aspirated reagent.  If the liquid-air transition is not seen at the  expected time,   one   of  several problems with the system are assumed, and the assay is  cancelled.
