Abstract: A fire retardant, intumescent, ceramic coating composition comprising an aqueous ceramic intumescent binder, intumescent ceramic particles, mineral fibers and a wetting agent is described. The intumescent ceramic binder comprises a mixture of a liquid alkali metal silicate, mineral fibers and a wetting agent. The coating provides enhanced intumescence and insulative properties suitable for application to structural steel and wood building materials.

Abstract: A modular electrical system kit interconnects a plurality of electrical wires of a power entry to at least one electrical outlet. The modular electrical system kit includes a plurality of circuit selectors, with each circuit selector being configured for interconnecting a respective selected combination of power entry wires to the at least one electrical outlet.

Abstract: The invention is directed to a lamp holder for carrying a fluorescent lamp, including two contact pins, with each contact pin having a diameter. A socket includes an inner hub, two slots and a conductor. The two slots are disposed on opposite sides of the inner hub. A spring biases the contact pins out of the slots. The conductor is associated with each slot, and is configured to engage each contact pin of the fluorescent lamp. The conductor and the inner hub define a clearance distance therebetween in a direction transverse to a longitudinal direction of each slot, with the clearance distance at all times being greater than the diameter of the contact pins. The clearance distance allows the contact pins to be moved away from the conductor by the spring, to thereby prevent electrical arcing when one of the contact pins is not fully engaged with the conductor.

Abstract: A double-diaphragm pump is designed to be molded almost entirely out of plastic and is provided with totally externally-accessible and serviceable check valves which do not require any significant disassembly of the pump itself. The pump is also fitted with a diaphragm which is formed from a uniform thickness of material and which have convolutions which are equally disposed on either side of the angle of elevation of the unstressed diaphragm. The pump is designed for mounting on top of a barrel or drum and has a set of radiused feet so as to fit snugly against the rim in an inlet pipe which fits into a bung plug having an eccentric opening such that the opening grips the inlet pipe and the plug may be rotated so as to snugly position the pump against the rim of the drum. The air valve to the pump is provided with U-cup seals in the housing.

Abstract: A multi-ply, fibrous material-based, conductive structure, and a method of making such a structure, which comprises as an integral structural member thereof at least one ply having an integral, continuous, uninterrupted, electroconductive barrier capable of intercepting and dissipating any electrostatic charges or discharges coming into contact with the structure. The ply provided with the electroconductive barrier can, during manufacture, be preselectively positioned with relation to the other, non-conductive plies comprising the structure to meet the specific performance demands of a user of the structure.

Abstract: A drive roller and roller system for positive transport of a web, which system utilizes a vacuum for drawing the web against a selected portion of the roller, thereby to control the linear speed and the tension of the web.

Abstract: A cutting knife assembly for severing a strip of material after it has been wound on a core and the winding operation is to be continued on a new core.
