Patent CA-2163945-A1 (CA)
Inventor: PAPPAS MICHAEL J
IPC: A61F2/38
Filed: 1995-11-28
Abstract: A femoral component with a femoral stabilizing implanted rod has condylar surfaces of different radii which mate with a thermoplastic bearing.  A mating tibial platform is stabilized in the tibia with a rod, the bearing translating on the platform in the posterior-anterior directions in response to knee flexion and extension.  The bearing bears the full extension load on congruent articulating contact regions with the condylar surfaces and lesser flexion loads via incongruent articulating contact. A hinge assembly is pinned to the femoral condylar component through a head having a depending shaft fixed to a thermoplastic tapered bearing axially floating and rotatably movable in a tibia platform component mating cavity.  The head passes through the bearing and stops the bearing translations at extreme posterior and anterior positions.  In a second embodiment, a projection on the tibial component mates in a recess in the bearing for controlling and limiting the amount of axial rotation of the femoral component relative to the tibial component as a function of the extent of flexion in a knee joint.

Title: Controlled Flow, Bursting Water Gun Release Mechanism
Inventor: D ANDRADE BRUCE M
IPC: A63H33/18
Filed: 1994-06-28
Abstract: The invention involves a water gun (1; 101) having at least one pressurizable air/water storage tank (13; 188, 189) and a release mechanism  including a plug valve (35; 135). The release mechanism also has a first spring (37; 137) connected to the plug valve which biases the plug valve to a closed position. There is also a delay spring (61; 161) located within a linkage (53, 55, 57, 59, 61, 153, 155, 157, 159, 161) that overcomes the forces of the first spring (37; 137) and internal water pressure holding the plug valve closed, such that the plug valve snaps open and there is rapid decrease of water pressure causing a burst of water to exit the water gun. When the delay spring can no longer overcome the internal pressure, the plug valve snaps closed. This creates a controllable burst and a realistic trigger release.

Patent CA-2168765-A1 (CA)
Title: Conductor locator adapter for electronic markers
Inventor: PARKINSON TIMOTHY A
IPC: G01V3/12
Filed: 1994-07-14
Abstract: An adapter for a conventional conductor locator allows the locator to additionally detect the presence of passive, electronic markers. The adapter includes an electronic marker locator and a wireless interface housed in a common body which may be releasably attached to the conductor locator. The electronic marker locator, which may comprise conventional circuitry, outputs a marker detection signal to the wireless interface, which conditions the signal so that it is compatible with the input sensor of the conductor locator.     The wireless interface includes an output antenna which is positioned adjacent the input sensor of the conductor locator when the adapter is attached thereto. If the conductor locator is of the type which may receive test signals at different operating frequencies, then the wireless interface also includes a modulator to selectively convert the marker detection signal to one of these operating frequencies. The electronic marker locator portion of the adapter may also be selectively adjusted to detect different discrete marker frequencies. The adapter may operate in a sleep mode, wherein the output signal of the wireless interface is disabled, but the wireless interface may still alert the user to the presence of an electronic marker by an audible alarm.

Filed: 1994-12-01
Abstract: Readily castable high density polyethylene (HDPE) films, preferably containing broad molecular weight distribution HDPE resin having treated upper skin layers and untreated lower skin layers, preferably coextruded, on each side. The treated upper skin layer is derived from a polymer, e.g. ethylene-propylene-butene-1 terpolymer, and the lower skin layer is derived from a polymer such as ethylene-propylene-butene-1 terpolymer and LDPE compounded with silicone oil. Such skin layers provide a film which is readily castable while maintaining the desirable properties of HDPE including dead fold, twist retention, TD tear and moisture barrier. The films are cast, and oriented in the solid state up to about two times in the machine direction and six times or more in the transverse direction to give films having good dead-fold characteristics making them highly suited for packaging, particularly for dry foods.

Title: Cell excluding sheath for vascular grafts
Inventor: BRUCHMAN WILLIAM CARL
IPC: A61F2/06
Filed: 1995-04-17
Abstract: The present invention is directed to a sheath for use with vascular prostheses derived from donor blood vessels, particularly mam-malian blood vessels. A vascular prosthesis of the present invention employs an external sheath around a donor blood vessel. The sheath pre-vents access to the donor vessel wall by host cells originating from perigraft tissue. While re-sistant to host cell ingrowth, the external sheath is permeable to the flux of macromolecules across its thickness. The exclusion of host cells by the external sheath and the bi-directional flow of macromolecules through the external sheath assists in maintaining the original function of the underlying donor vascular tissue of the prosthe-sis.

Une section RF/FI (21) reçoit une pluralité de signaux à spectre étalé. Une section RF/FI (22) reçoit une pluralité de versions synchronisées de la pluralité de signaux à spectre étalé. Des dispositifs numériques de temporisation (27, 28) retardent, d'une pluralité de temporisation par rapport à leurs versions synchronisées, les signaux à spectre étalé reçus. Des additionneurs (29, 30) combinent, sous forme d'une pluralité de signaux mixtes, les signaux à spectre étalé temporisés et leurs versions synchronisées. Un désétaleur (31) désétale les signaux mixtes sous forme d'une pluralité de signaux désétalés. Un dispositif d'amplitude (32) génère une pluralité de valeurs d'amplitude à partir des signaux désétalés. Un registre à décalage (33) mémorise une pluralité de valeurs d'amplitude précédente et de valeurs d'amplitude actuelle précédemment et actuellement produites par le dispositif d'amplitude (32). Un comparateur (34) compare les valeurs d'amplitude précédente aux valeurs d'amplitude actuelle et produit une pluralité de signaux de comparaison. Les dispositifs numériques de temporisation (27, 28), réagissant à ces signaux de comparaison, allongent ou raccourcissent la pluralité de temporisations.
