Abstract: A lightweight seat suitable for applications such as those in which the seat and occupant must withstand extreme amounts of applied force during use, e.g., encountering high waves in boats of seven meters (23 feet) or greater at speeds of at least 20 knots (37 km/h (or 10.3 m/s)).

Abstract: A rotationally molded article, preferably a boat or equivalent floatable marine structure, has a compressible truss structure either assembled to the mold and molded into the internal structure of the article, or added to a previously molded article and permanently attached in place. The compressibility of the truss accommodates key challenges to molding articles of large dimension without encountering buckling or twisting or other structural defects. For example, when molded integrally with the article, the compressible truss compresses as the thermoplastic material shrinks slightly during cooling. When added to a previously molded article, the compressible truss allows the article to withstand extreme amounts of applied force during use, e.g., encountering high waves in boats of seven meters [23 feet] or greater at speeds of at least 20 knots [37 km/h (or 10.3 m/s)].

Abstract: A cleat for use in a resilient flexible ground engaging portion of an article of footwear or an attachment for an article of footwear to provide resistance to slippage. The web of resilient material has an inner side and an outer side, and an aperture extending therethrough for receiving portions of the cleat assembly. The cleat assembly includes a base member, a projection member, and an optional cover member. The base member is an annular ring having a central opening and is arranged to be located within the opening in the web of resilient material. The projection member has a hub having an outer surface, from which a spike projects, and a flange projecting radially outward from the hub. The flange includes a peripheral bead. The projection member of the cleat assembly includes plural posts and the base member of that assembly includes plural lugs defining plural recesses therebetween.

Abstract: A tape hub including a support portion defining a peripheral surface around an axis adapted to frictionally receive a cylindrical inner surface of a core wound with tape, and axially spaced radial projections and locating members on the tape hub for positioning a first edge of the length of tape wrapped around the core at either of two discrete tape edge positions axially with respect to the hub. The tape hub is useful on devices that adhere tape along one edge of masking material to afford selecting different amounts of overlap between the tape and the masking material. The tape hub can have a plurality of radially extending hub portions having spaces therebetween and axially extending ribs on the hub portions defining its peripheral surface with the peripheral surface being adapted to frictionally receive the cylindrical inner surface of cores of slightly different inner diameters.

Abstract: A lock adapted to be used in conjunction with a slidably insertable card comprises a front housing segment and a rear housing segment, a bolt movable along a slide path from a normally open position to a fully locked position, a card housing, a lockout member with a first blocking position and movable to a second release position, a blocking member affixed to the lockout member, and normally disposed in the slide path of the bolt but movable out of the slide path of the bolt. The lockout member also has a peg that engages opening in the card and in the front housing segment constructed and arranged to receive the peg and allow free movement of the bolt into the fully locked position. An improper card or a proper card inserted improperly will not allow the peg to move into the opening, and the blocking member will remain in the slide path of the bolt, preventing the lock from being locked.

Abstract: A latch mechanism to secure a switch cover panel to a railroad track switch to cover the switch to avoid accumulations of ice and snow that would impede operation of the switch. An anchor bar is positioned beneath the housing of the cover panel. A linkage has a hook at a lower end that engages the anchor bar. The upper end of the linkage is connected to an over-center cam mechanism. A cam member is pivotally connected to a hinge plate secured to the upper surface of the switch cover panel housing. The upper end of the linkage is eccentrically connected to the cam member. A lever rotates the cam member on the hinge plate. Rotation of the cam member moves the upper end of the linkage from a relatively low position to a relatively elevated position to lift the hook for engagement with the anchor bar. Opposite rotation of the cam member releases the hook from the anchor bar.

Abstract: A fishing bobber has a self-contained electrical circuit therein, to provide an audible noise that signals when a fish has pulled sufficiently hard on the line supported by the bobber. The line is supported on the bobber and contacts are closed to complete a circuit to a noise-making buzzer or the like when the bobber is pulled sufficiently. The case of the bobber is preferably provided with a sound outlet so that the noise is not greatly attenuated by the bobber case.

Abstract: A heat retaining and snow deflecting cover assembly for railroad track switches is made up of panels that prevent snow and ice from building up in the regions where the switching rails must move. An inner panel assembly is mounted between the switching rails near the entry point of the track switch. Outer panels are secured along the outer sides of the main tracks. The panels also retain heat generated by conventional heaters. Deflecting panels are secured at both ends of the inner panel assembly to guide snow inwardly to the center of the track and away from the switching rails. The cover assembly is easily installed for winter use and removed when no snow is present.

Abstract: An air bag jack comprising an inflatable member made of a flexible material with a uniform thickness having a top section and a plurality of lower annular sections. The sections sequentially taper in diameter and have a base diameter smaller than the base diameter of the section below forming a generally pyramidal shape enabling the sections to collapse within one another upon deflation into a compact form. The top and bottom annular sections have the ability to conform to the object being supported and the surface of the terrain that is being used. Further the top section's top end wall has a concave surface preventing slippage during inflation. There are also a plurality of rings, one between each pair of adjacent sections extending around the outside of the jack to provide annular support for the wall section adjacently above. Each ring has a half-circle cross sectional configuration to prevent thinning of the inflatable member's wall in the area of junction between sections.

Abstract: A quick disconnect, lockable mounting for a C.B. (citizens band) antenna, or other type of antenna, which permits removing the antenna whenever desired simply by unlocking a key lock device, and taking off a cap carrying the antenna. Yet, when the cap is in position, it cannot be removed because the lock member securely holds it in position.The problem associated with breaking and stealing C.B. antennas (and radios, which are indicated as being present in a vehicle by the full antennas) has increased substantially, and the present device permits not only the quick disconnect and removal of the antenna, but the locking of the antenna to discourage thieves from attempting such removal.
