Abstract: A novel clip-on shielding strip is disclosed, intended particularly for cabinets for electronic equipment such as computer apparatus, and the like, where it is necessary and/or desirable to provide access doors or panels and to effectively shield such doors or panels at the closure interfaces to prevent or reduce the escape of stray radio frequency and/or electromagnetic interference radiation. The new clip-on shielding strip is characterized by a specifically advantageous physical configuration which, on the one hand, simplifies and expedites installation in the first instance and, on the other hand, assures excellent electrical grounding of the strip to the current structure, providing a high degree of reliability in the shielding function of the strip.

Abstract: A ventilated interlocking floor tile is disclosed comprising a lower layer including a heavy, substantially solid edge region provided with a plurality of interlocks for attachment with contiguous tiles and an upper layer securely fastened to the lower layer to form an upper floor surface including a unidirectional slip-resistant tread pattern. The solid edge region defines a cavity on the backside of the tile and includes a plurality of ventilating grooves extending from the cavity to the outer edge of the tile to accommodate the flow of air to and from the cavity.

Abstract: A ventilated interlocking floor tile is disclosed comprising a heavy, substantially solid edge region provided with a plurality of interlocks for attachment with contiguous tiles. The solid edge margins define a cavity on the back side of the tile, and the cavity is provided with a plurality of knob-like projections to support the tile surface while providing open space within the cavity. The solid edge regions are provided with ventilating grooves to accommodate the flow of air to and from the cavity.

Abstract: The disclosure relates to a pier bumper assembly intended particularly for marine application, for protecting dock pilings and dolphins from impact and chafing by contact with ships and barges. The bumper assembly is vertically oriented, and is secured over an exposed face of a marine piling. The pier bumper, which may have a substantial vertical height (e.g., 16 feet would not be unusual) is comprised of a vertically laminated stack of elastic plates, which are held under substantial compression by rods extending vertically through the stack. Along one side, the elastic plates are of deeply concave contour, to receive and partly embrace the generally cylindrical contours of the marine piling. A generally flat front face forms the impact surface.At two or more locations along the overall vertical length of the bumper assembly, one or more of the plates are recessed and curved, to form a retaining groove. Cables received in the retaining grooves serve to secure the bumpers to the marine piling.
