Patent CA-2187073-A1 (CA)
Title: Integrated introducer and drive rod positioning system for a fetal spiral electrode
Inventor: KENARD URION E
IPC: A61B5/288
Filed: 1996-10-03
Abstract: An integrated introducer and drive rod system used to position and attach a spiral-shaped, biological needle probe to a fetus during labor and delivery.  The system ensures that the sharp, pointed, probe (typically, a fetal spiral electrode) remains protected in a retracted position inside the introducer until attachment to the fetal scalp is desired.  The flexible drive rod of the system has a "C"-shaped safety ring with an outside diameter slightly less than the inner diameter of the introducer at a point on the introducer; a "C"-shaped radial web with an outside diameter only slightly larger than the inner diameter of the introducer creating an interference fit between the drive rod and the introducer; or a "C"-shaped segmented rib that engages the rear end of the introducer.  The introducer has an inner diameter sized to create an interference fit with the drive rod; a forward interior wall with an inside diameter slightly less than the outside diameter of the safety ring; a ramp on the front end of the introducer; a longitudinal slot disposed along its entire length; or a combination of one or more of these structures.  In combination, the structures of the drive rod and introducer resist but (upon exertion of a predetermined force on the handle of the drive rod) allow translation of the drive rod within the introducer.

Title: A vacuum apparatus having textured web-facing surface for controlling the rate of application of vacuum pressure in a through air drying papermaking process
Inventor: TROKHAN PAUL DENNIS
IPC: D21F11/00
Filed: 1997-08-29
Abstract: A papermaking vacuum apparatus having a web-facing surface adapted to support a papermaking belt and comprising a head, a body and at least one vacuumslot disposed in the head and defining an aperture on the web-facing surface. The vacuum slot is in fluid communication with the web-facing surface and extends from the web-facing surface to the body which is in further fluid communication with a vacuum source. The web-facing surface comprises a textured area in the region ofthe web-facing surface juxtaposed with the aperture defined by the vacuum slot. This textured area creates a leakage of at least about 35 Marlatts at a pressuredifferential of 7 inches of Mercury. This leakage eliminates the vacuum seal between a smooth backside of the papermaking belt and the web-facing surface of the vacuum apparatus.
Patent CA-2215140-A1 (CA)
Inventor: TROMPF MICHAEL
IPC: G06F17/30
Filed: 1997-09-24
Abstract: A data bank in accordance with the invention can be queried by means of linguistically unclear terme.  Since the meaning of linguistically unclear terms depends on the context in which they are used, each data set in the data bank contains associative values for the linguistically unclear terms, which indicate to what relative degree a respective linguistic value coincides with the corresponding data set as compared to the other data sets.  The data bank is derived from the first data sets and contains for each first data set a corresponding second data set in which the associative values are stored.  In addition a method of querying such a data bank is indicated, and a method of deriving such a data bank from the first data sets by using the rules of the fuzzy logic theory.

Title: Methods for g protein coupled receptor activity screening
Inventor: SADEE WOLFGANG
IPC: A61K38/08
Filed: 1996-05-21
Abstract: A method for screening G protein coupled receptors is provided in which G protein coupled receptors that are constitutively active are determined, such as by measuring receptor phosphorylation agonist independent signalling. When a G protein coupled receptor is found to be regulated by constitutive activity, then assay systems may be set up to classify test compounds as agonists, neutral antagonists, or negative antagonists with respect to G protein coupled receptor signalling and phosphorylation. Such determinations and screening are useful for selecting new pharmaceuticals potentially useful in treating disease states mediated by G protein coupled receptors, with applications including treatments in conjunction with narcotic analgesia.

Filed: 1997-08-27
Abstract: A novel polypeptide exhibiting a growth promoting activity on hematopoietic stem cells; a gene encoding this polypeptide; an antibody reacting specifically with the polypeptide; a process for isolating the above-mentioned gene; and a vector to be used in this process. Thus, the pathologies of various hemopoietic organ diseases caused by abnormalities in hematopoietic cells and bone marrow inhibition can be clarified and, in its turn, these diseases can be diagnosed or treated. Also, it becomes possible to amplify hematopoietic cells in vitro for marrow graft required in treating these diseases or to elevate the gene transfer efficiency into hematopoietic stem cells for gene utilization. Moreover, the above-mentioned process and vector for isolating the SCGF gene are applicable to the clarification of other novel genes and thus contribute to the development of genetic engineering techniques.
