Patent CA-2097341-A1 (CA)
Inventor: LHYMN CHANG
IPC: C22C1/00
Filed: 1993-05-31
Abstract: ABSTRACT OF THE DISCLOSURE A fabrication method of  strengthening metallic alloys by composite technology has been developed by mixing steel shots or aggregates with conventional alloys, thus preventing cold flow or creep.   Preventing creep is advantageous in thermal plugs which must withstand fluid pressure without leakage until subjected to dangerous temperatures such as caused by fire.  The matrix alloy primarily consists of some or all of copper, magnesium, bismuth, tin,  lead,  cadmium,  and  indium and the particle material  is preferably iron or steel.  New alloys exhibit a higher strength against a hydrostatic gas pressure than that of conventional matrix phase containing no reinforcing particles, while maintaining the melting temperature of new alloys in the same range of conventional unreinforced matrix alloy.  The mixing of steel particles with the matrix is achieved by employing a flux such as ammonium chloride.          Other reinforcible matrix alloys include tin-based,  lead-based, copper-based,  zinc-based,  cadmium-based,  indium-based,  bismuth-based, magnesium-based, and aluminum-based alloys used for dynamic and structural parts requiring strength and creep resistance.          Ferroaluminum shots are comprised primarily of iron and aluminum and they are light, relatively nonreactive with zinc, and bondable to aforementioned matrix alloys by using inorganic acid-based fluxes of zinc chloride, ammonium chloride, a mixture of chlorides, or a mixture of chlorides and fluorides.   Other fluxes such as organic acid-based chemicals work as a cleaning agent when they can clean surface oxides of both the matrix alloy and reinforcing shots.     Materials   for  alternative   reinforcement   include conventional  steel  or  iron  shots  coated with  sodium nitrite, ferroaluminum shots coated with sodium nitrite, nickel, copper, their base alloys,  refractory metals,  copper or nickel-coated metals, copper or nickel-coated plastics, and copper or nickel-coated ceramics.

Abstract: A valved catheter (10) having an elongated, flexible tubular element (18) defining a lumen (20) extending along an axis substantially parallel to the central axis (A) of said tubular element, and a bidirectional check valve assembly (12) near its distal end (16) which controls fluid flow in the tubular element. The valve assembly includes an aspiration valve (24) offset from the tip of the distal end of the tubular element and an infusion valve (26) formed at the tip of the distal end of the element. The aspira-tion valve is generally defined by one or more ports (24', 24") in the tubular element and a sleeve (30) within the tubular element underlying the ports, where the sleeve normally closes the ports. The aspiration valve (24) permits fluid flow from the patient's bloodstream into the tubular element (18) when the static fluid pressure inside the tubular element distal end (16) is lower than the static fluid pressure outside the aspiration valve by an amount sufficient to displace the sleeve (30) to allow fluid flow through the ports. The infusion valve (26) includes a throat (42) formed in the tubular element distal end (16) which tapers down to a mouth (44) formed by jaws (or "lips") (48, 48') at the tip of the tubular element. The mouth (44) is essentially closed to fluid in-flow from the patient into the tubular element and normally closed to fluid outflow from the tubular element into the patient. The infusion valve (26) permits fluid infusion into the patient's bloodstream when the static fluid pressure inside of the tubular ele-ment distal end (16) is higher than the static fluid pressure outside of the infusion valve (26) by an amount sufficient to force the mouth (44) open. A bidirectionally valved mutiple lumen catheter (10') is also disclosed.

Title: Twin Conical Refiner with Dual Ribbon Feeders
Inventor: DAHLQVIST KARL T G
IPC: D21D1/22
Filed: 1994-03-03
Abstract: Apparatus and method for the mechanical refining of high consistency lignocellulosic feed material in a frustoconical refining zone, by facilitating the backflow of steam generated in the refining zone through the upstream feed zone which, despite the backflow of steam, imparts outward force on the feed material sufficient for the material to enter the refining zone and pass therethrough, without blockage or flow interruption.  This is accomplished by providing, immediately upstream of the frustoconical refining zone (46), a hybrid feed/grinding zone (104), which acts on the wood chips with relatively high refining intensity at low refining power, so as to reduce the size of the material and outwardly convey the material by centrifugal force into the frustoconical refining zone against the backflowing steam, but without generating steam in the hybrid zone.  The hybrid zone receives chips from a feed screw (84) which preferably rotates at the same speed as the rotor (20) portion of the frustoconical refining zone and hybrid zone.  The feed screw is shaped (e.g., as a ribbon screw) so that the chip material is easily "handed-off" to the entry of the hybrid zone, while establishing an open channel (166) between the chip material and the shaft of the feed screw, for conveying backflowing steam away from the hybrid zone. First pressure control means (136) are provided in fluid communication with the backflow steam channel, for removing the backflowing steam from the refiner at a controlled pressure, thereby controlling the retention time of the material in the frustoconical refining zone (146).

Title: Fishhook setting device
Inventor: TESSIER YVAN
IPC: A01K97/01
Filed: 1994-09-02
Abstract: The invention provides a device for automatically setting a hook in a fish. The invention uses a simple post to which the major components are assembled, which post has a pointed bottom for insertion into ice or snow, for ice fishing in the winter, or to which appropriate clamping means may be attached so that the post can be connected to other supports such as a pier or the gunwale of a boat for fishing during the other seasons.   The invention incorporates a signal flag and it also incorporates means for avoiding activation if a fish only makes a passing attempt at taking the bait, rather than a full strike.   This means takes the form of a lever and a first spring-loaded rod attached to a recoil mechanism.  If the rod is caused to move with sufficient force it will actuate the recoil mechanism which, in turn, moves the lever and releases a second spring-loaded rod, effectively setting the hook in the fish's mouth.  The recoil mechanism is adjustable so that its sensitivity can be set in accordance with the species of fish being sought.  In addition, the recoil mechanism is provided with appropriate means to counteract the effects of wind and hence avoid inadvertent actuation when there is no fish striking at the bait.
