  • Patent number: 6081952
    Abstract: An electrical T-fastener pliers has jaws (1, 3) with grip bays (8, 9, 39, 40) that are positioned on T-joint fastener jaws (15, 16, 17, 18) to be clamped onto targeted wires (19) by hand-squeezing handles (2, 4) of the electrical pliers. Jaws of the T-joint fasteners (12) are pressured against jaws of the pliers by outward pressure of outwardly sprung T-joint fasteners against designedly opened pliers jaws or optionally by inward pressure of the pliers jaws against jaws of unsprung T-joint fasteners (13). This provides a spring-pressured containment of a T-joint fastener while the pliers are being positioned in T-joining relationship to targeted electrical wiring. The handles can be extended at angles from the jaws to position a bottom handle designedly removed from a working surface in order to provide finger space between a working surface and in order to facilitate positioning the jaws under wires in close proximity to surfaces.

  • Patent number: 6081954
    Abstract: A loading dock includes a dock leveler movable between raised and lowered positions. The dock leveler includes a dock board and a lip assembly that can be horizontally extended and retracted relative to the forward edge of the dock board. The ability of the lip to extend and retract horizontally means that the dock board does not have to be raised as far to extend the lip as in prior dock levelers having a pivotally mounted lip. This eliminates or reduces the need for toe protection structure at the sides of the dock board and enhances manufacturing economy without compromising safety.

Each one of the linkages moves in reversed orientation, such that a pivotal movement is initiated to cause an upward and a downward movement simultaneously while the operating device is activated. The movement of the operating device in reversed orientation will accomplish the extending or folding of the tubes.

  • Patent number: 6081968
    Abstract: A hinge assembly for an enclosure for electrical apparatus includes a hinge pin non-rotationally fixed to either the door or the door jamb. A hinge housing is secured to the other of the door and the door jamb and clamps the hinge pin with a compression fit. The housing includes an angle member forming an internal corner and a clamping member having clamping flanges forming at least one, and preferably a pair, of spaced apart, external corners with corner recesses smaller in radius than the hinge pin in which the hinge pin is received and wedged into the internal corner of the angle member. Clamp tabs on the clamping flanges are secured to one of the flanges on the angle member such as by rivets to produce the compression fit. An elongated flat body on the clamp member and a mounting flange on the angle member abut and are secured to the other of the door and door jamb by common mounting fasteners.

  • Patent number: 6081972
    Abstract: The invention concerns a textile machine operating on fiber band with a feeding device for the fiber band and a guide element for the fiber band and further provided with a band monitor for the discovery of band breakage. The band monitor (BW, BW1, BW2, BW3) is placed always in the area of the guide element, in particular one band guide (BF) and another band guide element (FE, FE1, FE2, FE3) in the area of the band monitor (BW, BW1, BW2, BW3). The running time behavior of the fiber band (FB) is directly improved by the guide element (FE, FE1, FE2, FE3), that is, the vibrations of the fiber band (FB) are damped. This will avoid a situation wherein false alarm signals are given because of an originally vibrating fiber band at the band monitor.

  • Patent number: 6081974
    Abstract: An anchor device for use with a security slot in a portable electronic article that provides an anchor for attaching a cable or other security device. The anchor device includes an internal member, an external member, and a securement for securing them together. The internal member includes a right angle portion inside the portable article that is approximately parallel to the inside wall. The external member has a clamping surface that abuts the outer surface of the portable article. The external member has an aperture into which the internal member fits and is secured either permanently or removably. The preferred removable securement is a screw that extends through the external member and into a threaded hole in the internal member. The securing device denies access to the screw when engaged with the external member. The external member provides an anchor for removably attaching the security device.

    Abstract: A hook for webbing comprises a metal rod bent in a single piece having an upper cross piece (1) intended for receiving a webbing, said cross piece transforming into two legs (2, 2') which converge from opposite ends thereof so as to form a loop part together with the cross piece, at least one of the legs transforming into a curved portion (4, 4') forming a lower hook part (5). The curved rod portion (4, 4') of the hook part (5) has a height which is larger than the width thereof in a cross-section in the area of the bottom of the hook part and thus a moment of inertia which is larger than the moment of inertia of a conventional round rod. In addition, the cross piece (1) has a cross-section-wise larger height than width and is, with the geometrical normal or major axis thereof, obliquely inclined in relation to the legs, more precisely into a plane of forces extending towards the hook part (5).

  • Patent number: 6081979
    Abstract: A piezoelectric ceramic-polymer composite is made of a substantially two-dimensional polymer matrix and a monolayer of sintered piezoelectric ceramic granules dispersed throughout the matrix so that each granule has an upper portion protruding from one side of the matrix and a lower portion protruding from the opposite side of the matrix. The composite is formed by partially embedding a monolayer of sintered piezoelectric ceramic granules in a pliable material, then partially covering the granules with a polymer resin, curing the resin to form a matrix and removing the pliable material. A transducer is formed by flattening the upper and lower portions of the granules to form coplanar top and bottom surfaces parallel to, but not coplanar with the surface of the matrix, then electroding the granule surfaces, attaching top and bottom cover plates, and sealing the transducer around the edges.
