Abstract: A system and method for preventing damage to a fuel cell stack resulting from impurities in the product stream from a fuel processor, such as may occur should the separation region of the fuel processor fail. The system and method include detecting the concentration of at least one component of the product stream and isolating the fuel cell stack should this concentration exceed an acceptable threshold level. Examples of impurities in the product stream include; carbon monoxide, carbon dioxide, methane and water.

Abstract: A plug is disclosed that provides for electrically connecting an electronic device, such as a television, to a signal port providing power, ground, audio/video, control and status-reporting signals to and from the device. The signal port is connected to terminals in a receptacle and the plug includes joining structure that can be inserted in or otherwise coupled to the receptacle to mechanically support the plug and the device. The joining structure is provided with retractable contacts to make the electrical connections with the terminals in the receptacle. The retractable contacts avoid damage when the joining structure is inserted into a receptacle that is fouled with debris because the contacts retract on contact with the debris rather than being bent or pushed out of place.

Abstract: A surface treated metallic material according to the present invention comprises a metallic substrate and a metallic compound layer formed thereon, wherein the entire surface of the metallic compound layer is covered with minute, upright, scaly protrusions. The width in the major axial direction of the scaly protrusions is between 0.05˜0.5 &mgr;m and the thickness between 0.01˜0.1 &mgr;m, and the thickness of the metallic compound layer is between 0.1˜1.0 &mgr;m. The metallic compound layer incorporates one, or two or more of, the materials selected from the group consisting of chromium oxide, chromium hydroxide, niobium oxide, niobium hydroxide, rhodium oxide, rhodium hydroxide, vanadium oxide, vanadium hydroxide, palladium oxide, palladium hydroxide, nickel oxide, and nickel hydroxide. By using surface treated metallic materials of this type, bonding strength to a resin layer can be improved.

Abstract: Methods for producing medium-density articles from recovered high-density tungsten alloy (WHA) material, and especially from recovered WHA scrap. In one embodiment of the invention, the method includes forming a medium-density alloy from WHA material and one or more medium- to low-density metals or metal alloys. In another embodiment, medium-density grinding media, such as formed from the above method, is used to mill WHA scrap and one or more matrix metals into particulate that may be pressed and, in some embodiments, sintered to form medium-density articles therefrom.

Abstract: A small fin extends radially aft from a golf club head to resist rotation of a golf club shaft about its longitudinal axis. The fin is aligned relative to the club head so as to produce minimum drag when the club is drawn smoothly through the desired arc without rotating the club shaft about its longitudinal axis. Rotation of the shaft about its longitudinal axis displaces the fin from its minimum drag position and hence puts the fin in disequilibrium, such that the drag is greater on the side of the fin that would urge the fin back into its equilibrium position, thereby rotating the shaft back into its correct position.

Abstract: A surrogate top tube for use in attaching bicycle without top tubes to vehicle-mounted carriers. The top tube includes yokes at each end for selective attachment to the seat tube and a vertical portion of the handlebars. The top tube may includes structure to prevent the yokes from rotating relative to each other about an axis extending therebetween. The yokes may also include a safety retainer to prevent the yoke from accidentally opening.

Abstract: A reel has a housing, an axle, a handle, a wheel and a friction element. The friction element is mounted in the housing and presses against the wheel. The friction element is made of an elastic material. The friction element includes an inverse U-shaped base and a protruding contact pad extending up from the base portion to press against the outer edge of the wheel. Consequently, the wheel can be stopped in any desired position by the friction element, and the degree to which the canopy can be expanded is controlled. The use of the suspended sunshade becomes more versatile.

Abstract: A collapsible massage table includes two folding table pieces hingably connected to each other so that when the table is set up it has four comer regions. Each corner region is supported by a leg that is connected to the table via a folding link. Each link has a cable portion that stabilizes the link in an orientation directed toward the ground when the table is set up.

Abstract: A rack assembly for carrying recreational equipment on a vehicle. The assembly includes at least one mount attachable to the vehicle, and a load-carrying support member coupled to the mount and configured to support the recreational equipment adjacent the vehicle. At least one securing apparatus is associated with the load-carrying support member and configured to secure the equipment to the support member. The securing apparatus includes a strap adapted to extend at least partially around the recreational equipment, and a ratchet drive mechanism adapted to receive and grip one end of the strap. In one embodiment, the ratchet drive mechanism includes at least one drive actuator that is operable to grip successive portions of the strap and draw it tight around the recreational equipment.

Abstract: A releasable jig for positioning and stabilizing while properly orienting an anchor bolt during construction where such a bolt is placed in wet, curing concrete. The jig includes a tube-like portion which is slightly tapered to effect a friction grip on such a bolt, and this tube-like portion includes a slot-like opening which exposes the outer, upper end extremity of a bolt so that the position of this end extremity can clearly be seen during installation.

Abstract: The invention provides a one-stage method of measuring antithrombin (AT) activity in a sample. In the method, a diluted sample is mixed with AT-deficient plasma containing intrinsic coagulation enzymes, an AT augmenting compound such as heparin, a phospholipid and an activator of the contact phase of the intrinsic coagulation pathway. Following addition of calcium ions, coagulation time is measured and compared to a reference standard to determine the level of AT activity in the sample.

Abstract: A modular display panel and edge latching system therefor which employs concealed movable latching mechanism that can be actuated between adjacent panels set up, for example, on a floor to lock the panels into vertical alignment and against any tendency of floor unevenness to cause adjacent panels to become misaligned vertically. The components in the latching mechanism which create vertical position locking are actuated by the insertion of actuators typically carried as downward projections on other panels which rest on top of directly floor supported, underlying panels.

Abstract: A stowable support system having an arm and an attachment member pivotal through a plurality of angular positions relative to the arm. The arm includes a follower assembly with a surface portion of a first contour, with the attachment member including a surface portion of a second contour that is cooperative to the first contour. A rest position is defined by at least one of the plurality of angular positions, in which the surface portions of the follower assembly and attachment member are in mating contact. The follower assembly and attachment member are biased toward engagement with each other, with at least one of the attachment member and the follower assembly being configured to be resiliently deformed when the attachment member is pivoted out of the rest position.
