摘要： A gel and container means capable of protecting a binding post and drop wire from moisture and corrosion is provided which will effectively prevent the exposure of the drop wire and binding post cap and screw from moisture and corrosive atmospheres without the need for a pressure maintaining means other than the combination of the cap and gel. The pressure of the gel is maintained on the binding post through the extraction of plasticizers from the container means causing a shrinkage.

摘要： This invention provides a process for making metal oxide varistor precursor powder comprising (a) dissolving soluble precursors of the additive metal oxides, e.g. bismuth nitrate as precursor for bismuth oxide, in an aqueous solution, (b) forming a suspension or slurry in the aqueous solution of a powder of the desired primary metal oxide, e.g. zinc oxide, having the desired particle size, (c) adding a precipitating reagent to convert the additive metal from the soluble precursor form to the oxide or hydrous oxide form and precipitate the oxide or hydrous oxide in the presence of the primary metal oxide particles, (d) removing water and by-product salts to form a powder. The resulting varistor precursor powder contains smaller particles of the additive metal oxides evenly distributed throughout larger particles of the primary metal oxide. Varistors prepared from the resulting powder can be sintered at temperatures lower than conventionlly used, for example 900.degree. C.-1000.degree. C. and the resulting varistors exhibit properties of volts per grain boundary value higher than conventional varistors for example 3.75 to 4.5 and dielectric constants lower than conventional varistors, e.g., under 1000.

摘要： An enclosure especially suitable for telecommunications applications. The opening and closing of the cover of the enclosure is about an axis that permits the installation of the enclosure in environments requiring a minimum of clearance. More specifically, the cover is affixed to a side of a base member of the enclosure opposite to an open face; and the cover has a centrally located hinge which permits the cover to rotate closely about the axis of the open face.

摘要： An actuator such as an electrical switch which responds to an event such as a change in temperature by movement of an element between first and second positions, for example in which an electrical circuit is open and closed respectively, includes a dimensionally heat-recoverable component which, on recovery when the actuator is exposed to a high temperature, changes configuration so that a portion of the component is positioned between the element while in its first position and a support for the component, so as to restrain movement of the element towards its second position. This allows the actuator to be locked as a result of exposure to the high temperature, which can be desirable, for example, because of damage to equipment to which the actuator is connected.
