Title: Detachable blood seal
Inventor: ERSKINE TIMOTHY J
IPC: A61M39/10
Filed: 1997-09-15
Abstract: A removable blood seal is provided for preventing the leakage of blood during the placement and use of vascular catheters and similar devices. The structure of the blood seal includes a housing having a proximal end and a distal end. The distal end is configured such that a catheter can be removably attached to the distal end. The proximal end is configured such that a needle hub can be fit to the proximal end. The housing includes an internal channel disposed through the housing and configured such that a needle can pass through the channel. An elastomeric seal is placed securely within the channel such that it substantially blocks fluid flow through the channel. The seal is preferably configured of an elastomeric material such that if a needle penetrates said seal and is then later removed, said seal substantially closes the internal channel to fluid flow.

Abstract: Une calotte pour bombe aérosol ayant une ouverture centrale pour un ajutage et un bord externe prévu pour être fixé à l'extrémité ouverte d'un corps d'une bombe aérosol. La calotte de la bombe aérosol est en un métal relativement mince, dans la plage de 0,005 à 0,013 pouces (0,127 à 0,330 mm) d'épaisseur, lorsque le métal est l'acier, et de 0,005 à 0,018 pouces (0,127 à 0,457 mm) d'épaisseur lorsque le métal est l'aluminium. L'épaisseur de la calotte est inférieure à l'épaisseur requise pour empêcher la distorsion ou le retournement de la calotte aux pressions légales minimales à l'intérieur de la bombe aérosol. Cette calotte présente une forme sensiblement convexe (dôme) et elle s'étend depuis son bord externe jusqu'à une ouverture centrale et elle est exempte de tout creux en forme de canal au voisinage de son bord externe. Dans un procédé pour réaliser la calotte du récipient aérosol, la calotte est fixée à un corps de bombe par une opération de sertissage conventionnel. La calotte, à l'étape initiale, a un creux en forme de canal au voisinage de son bord externe qui est utilisé dans l'opération de sertissage pour recevoir un mandrin de sertissage. Ensuite, le creux en forme de canal est retourné vers l'extérieur par la pression. Dans un autre procédé de sertissage du récipient selon l'invention, la calotte à paroi mince est dépourvue de creux en forme de canal et est placée sur un bord ouvert de corps de bombe. Un ou plusieurs bras extensibles sont introduits dans le corps en face de cylindres de sertissage, pour sertir la calotte sur le corps de la bombe.

Patent CA-2232175-A1 (CA)
Inventor: GRENKE EDWARD
IPC: E21B/
Filed: 1995-09-14
Abstract: A braking mechanism, for controlling the release of energy in a rod string (34) for a down-well rotary pump (33), incorporates a rotary member (16) positioned in the energy loop from a prime mover to the top end of the rod string, requiring that the rotary member rotate at a consistent speed ratio and direction with respect to the top end of the rod string. The rotary member drives a fluid pump through a slip clutch so that when the top end of the string rotates in the normal direction, the clutch slips and does not run the fluid pump. However when the top end of the rod string seeks to rotate in the opposite direction, for example on shut-down or power failure, the fluid pump is operated to pump fluid from a reservoir (20) and back to the reservoir in a closed loop which includes a mechanism for restricting fluid flow.

Title: Material for enhancing water tolerance of composite boards
Inventor: SLEETER RONALD T
IPC: C09J191/00
Filed: 1998-08-27
Abstract: A method of enhancing water resistance of composites uses a water repellant material which may be applied toward and other fibrous vegetable materials. The method begins with a saturated vegetable or animal fat triglyceride having a low iodine value. The triglyceride is rendered in a form which may be a fine powder, an emulsion, or a dispersion in a liquid. The sprayable triglyceride and a bonding agent are applied to the fibrous materials, preparatory to a press binding. There, the sprayed material is subjected to a hot press cycle in order to form a bonded fibrous composition. The low Iodine Value triglyceride may be selected from a group including hydrogenated vegetable oil, palm oil, stearine, winterized low IV fractions, soy stearine, animal fat, hydrogenated animal fat, and fractionated fats or blends of these materials.
Patent CA-2247322-A1 (CA)
Title: Method of correcting the determination of workpiece and tool positions in machine tools
Inventor: WELB SOEREN
IPC: G01B11/03
Filed: 1997-01-17
Abstract: The invention concerns a method of correcting the determination of positions of workpieces and tools which can be moved relative to one another in machine tools, in particular CNC machining centres, by means of measuring systems internal to the machines. Machining inaccuracies caused by changes in the positions of the workpiece and/or tool owing to heat in the working region of the tool can be avoided if the workpiece and tool are moved with associated measuring points or measuring edges through a stationary optical test barrier, simultaneously or at short intervals one after the other. If the test barrier is interrupted, the respective positions of the workpiece and tool are determined by means of the measuring system internal to the machine. The positions determined are compared with stored positions determined during a previous measurement, and the difference between the determined position and the stored position is used to correct the machine control. The invention further concerns a machine for carrying out the method.

Abstract: The present invention relates to a method for improving the success of a transplantation which at least addresses to one of the most serious problems: transplant survival. The method comprises the steps of transplanting donor cells in a patient in need for such a transplantation, the transplantation being made in the presence of an agent blocking the interaction between a ICAM1 molecule located at the membrane surface of the donor cell and a LFA-1 molecule located at the membrane surface of the patient's leucocytes, which blocking increases the viability of said transplanted donor cells by at least about four fold. The agent blocking this interaction is an anti-LFA-1 antibody which is injected to the host at the time of transplantation or an anti-ICAM-1 antibody fragment which is not capable of fixing complement, such as a F(ab)2 fragment.
