Title: Catheter release mechanism
Inventor: BOGERT DAVID L
IPC: A61M5/31
Filed: 1996-06-05
Abstract: A catheter insertion device incorporating a simple lever and clip structure which will safely lock a catheter hub of a catheter assembly to a normally disposable cannula housing and guard structure and which, in a simple mode, enables separation of the catheter hub from the cannula assembly or structure upon retraction and protective guarding of the used cannula.  Specifically, an aspect resides in providing the lever release clip for a safety catheter which upon unlocking and releasing of the catheter hub concurrently pushes the catheter hub off a nose guard of the cannula assembly, while enabling a physician or clinical personnel to release the catheter by employing only one hand. A further embodiment is adapted to enable separation between the catheter hub of a flexible catheter and the needle or cannula arrangement of'a catheter insertion device by simply manipulating a lever arranged on a cannula structure or nose guard thereof by simply pushing against a push-tab element.

Patent CA-2194695-A1 (CA)
Title: A direct conversion receiver
Inventor: SMITH CHRISTOPHER NIGEL
IPC: H04L27/14
Filed: 1995-05-10
Abstract: The receiver includes input means comprising an antenna and blocking filter, the output of which is connected to an amplifier. The input signal is split and mixed with an in-phase and quadrature phase signal generated by an oscillator in a mixer circuit, respectively. An output from each mixer circuit is applied to a low pass filter and to an input of a limiting circuit. The output from each low pass filter is applied to an input of a summator circuit respectively, a first of which is arranged to sum the in-phase and quadrature phase signals, and the second of which is arranged to subtract the in-phase and quadrature phase signals to generate a respective output signal having an axis intermediate of the in-phase and quadrature phase signal axes. These signals, together with the in-phase and quadrature phase signals are passed through a limiting circuit respectively, to a decoder circuit for recovering the data. The output of the limiting circuits represents signals quantised to eight possible phase states separated by 45~. When the input signal is GFSK  modulated the vector will always cross at least one axis, so the direction of rotation can be established prior to data recovery. In an alternative embodiment a ratiometric combiner may be used instead of the summator circuits, and this is particularly useful for .pi./4-DQPSK modulation, where the phase excursion per symbol is ~ 45~ or ~ 135~ depending upon the bit pair combination, and in this embodiment a minimum of eight axes are generated giving sixteen sectors and 22.5~ phase resolution.

La matière active du côté électrolyte (33) de la cathode à diffusion gazeuse comprend une matière de support catalyseur particulaire présentant une aire de surface comprise entre environ 50 et environ 2000 m?2¿/g; sur les particules de cette matière de support sont déposées de 0,1 à 50 % en poids, en fonction du poids de la couche active, de particules d'or ou d'alliage d'or présentant une taille moyenne ?40 mais inférieure à environ 200 .ANG.. Ces particules d'or ou d'alliage d'or sont essentiellement sélectivement catalytiques pour la réduction de l'oxygène en peroxyde (par ex. HOO?-¿). Les configurations d'écoulement de l'électrolyte sont conçues pour éviter toute perte de peroxyde résultant de l'oxydation au niveau de l'anode (39). Lors du fonctionnement de l'élément, on peut obtenir un produit avec un rapport hydroxyle:perhydroxyle inférieur à 2:1.

Title: Methods of preparing organs for cryopreservation and subsequent transplantation
Inventor: FAHY GREGORY M
IPC: A01N1/02
Filed: 1995-08-11
Abstract: The invention relates to the field of organ and tissue perfusion. More particularly, the present invention relates to a method for preparing organs, such as the kidney and liver, for cryopreservation through the introduction of vitrifiable concentrations of cryoprotectant into them. To prepare the organ for cryopreservation, the donor human or animal, is treated in the usual manner and may also be treated with iloprost, or other vasodilators, and/or transforming growth factor .beta.1. Alternatively, or additionally, the organ which is to be cryopreserved can be administered iloprost, or other vasodilators, and/or transforming growth factor .beta.1 directly into its artery. The invention also relates to preparing organs for transplantation by a method for the removal of the cryoprotectant therefrom using low (such as raffinose, sucrose, mannitol, etc.), medium (such as agents with intermediate molecular weights of around 600-2,000) and high (such as hydroxyethyl starch) molecular weight agents osmotic buffering agents. The invention is also directed to new post-transplantation treatments such as the use of transforming growth factor .beta.1, N-acetylcysteine and aurothioglucose.
Patent CA-2199574-A1 (CA)
Inventor: HOPKING RANDALL K
IPC: G01L1/26
Filed: 1997-03-10
Abstract: A load to be measured is transmitted to a load cell, such as a compression load cell, through a double piston, single cylinder load transmitter that has a pressure chamber between two pistons in the single cylinder. One piston bears against the load. The other piston bears against the load cell to form a floating link between the load and the load cell when a sufficient pressure is introduced into said pressure chamber to prevent unwanted, off--center load application force components from adversely affecting any measured results. Preferably, at least one axially outwardly facing end surface of the piston bearing against the load cell has a curved end surface area. A rocker pin with a pressure controllable variable length may be formed by making both axially outwardly facing end surfaces curved. Several load transmitters may be arranged in parallel to transmit larger loads into a load cell.
