Abstract: An electrically grounded, static absorbing drapery installation which employs a decorative conductive drapery fabric having disconnectable electrical connector means installed thereon for connection to the ground terminal of a conventional wall outlet for dissipating accumulated static charge. The electrical connector means do not interfere with opening and closing of the drapery in its installed condition. Also the electrical connector means can be selectively disconnected to permit cleaning or repair of the drapery.

Abstract: An antistatic chairmat for preventing electrical shocks due to triboelectricity. The chairmat consists of a transparent plastic material and includes an array of semiconductive inserts with a ground connection. The preferred design incorporates a conductive or semiconductive lower layer, and an insulative intermediate layer which may be a printed design, or sheet. The lower conductive or semiconductive layer provides electrical continuity to ground via studs at the bottom of the semiconductive inserts. An alternative antistatic chairmat includes a plurality of semiconductive layers bridged by one or more conductive grounding clips.

Abstract: An electronic cabinet having a conductive frame and a conductive removable access panel or door is grounded by a ground button. The ground button comprises a donut-shaped core of resilient material supported by a mounting plate. A layer of knitted-metal wire mesh at least partially surrounds the exterior of the core and the mounting plate. The button is constructed to be mounted to one surface of the cabinet with the layer of knitted-metal wire mesh in contact therewith. When the access panel or door is closed, the button is deformed between the frame and access panel or door to provide a positive conductive leak path therebetween.

Abstract: Charge accumulation inhibitor (100) in FIG. 2 of fuel filler pipe (200) prevents an accumulation of a portion of electrical charge that a conductor such as cap flange retainer (302) or a fuel dispending metallic spout may otherwise, in absence of inhibitor 100 or grounding of the spout, acquire. Inhibitor (100) is made of semi conductive material such as a nylon 12 filled with conductive particulate to yield a volume of resistivity of between about 1.times.10.sup.2 -1.times.10.sup.5 ohm-centimeters.

Abstract: When explosive fuels such as hydrocarbons are pumped into or out of a barge or tanker, a metallic conduit having an insulated flange therein is typically connected to the barge. The method of this invention involves connecting the barge to the earth through a barge-grounding cable, connecting the metallic conduit to the earth through a conduit-grounding cable, whereby a grounding test circuit is established with a current source connected between the earth and the grounding cables. A flange resistor is connected across the insulated flane to form a flange circuit. The currents flowing through the grounding cables are being continuously monitored in the grounding circuit to determine the presence of a broken connection or of an ineffective electric contact. A continuity test is also continuously being made of the flange insulation in the flange.

Abstract: Construction parts are protected against lightening by a layer which releases a cloud of ionized and ionizable particles to spread the area affected by the lightening flash and to fan out the current path. The layer may include additives which swell when heated to increase the volume and density of the cloud. An electrically and thermal conductive layer or two such layers each having predominantly one of these properties is provided underneath the releasing layer.
