Patent EP-0050915-A1 (EP)
Inventor: MOSIER DOUGLAS R
IPC: H01H47/00
Filed: 1981-09-09
Abstract: A system adapted to remotely control a transformer relay (12). The load switch (36) of a transformer relay (12) is controlled by controlling the direction of current flow in the secondary winding (34). A switch module (26) is coupled with two wires (28) to the secondary winding (34) of the transformer relay (12) providing a unidirectional current flow above a predetermined threshold in the secondary winding (34) in response to a control signal. The unidirectional current flow may be selectively controlled in either direction or may be only purely unidirectional. A control module (14) is then coupled to the switch module (26) momentarily producing the control signal in response to an external stimulus. The switch module (26), the control module (14), or both draw a quiescent current from the secondary winding (34) of the transformer relay (12) when the switch module (26) is not activated. The quiescent current is of an amount which is less than the predetermined threshold. In one embodimentthe voltage and current at the control module (14) are limited to values less than those available at the secondary winding (34) of the transformer relay (12).

Abstract: The present disclosure is directed to an electrode active layer or sheet containing from about 60 to 85 weight % active carbon in intimate admixture with 15 to 40 weight % fibrillated PTFE, a process for making said active layer laminated electrodes containing said active layer, and a process for forming said laminates. This electrode has improved strength and is capable of operation at high current density with resistance to mechanical failure due to blistering of the electrode. 
     The process for making the electrode is characterized by combining a dilute dispersion of smaller polytetrafluoroethylene particles with a suspension of catalyzed or uncatalyzed larger active carbon particles to discontinuously coat active carbon with PTFE; fibrillating same; comminuting said fibrillated PTFE/active carbon mix; and then rolling same into a self-sustaining, coherent sheet form. Alternatively, the sheet form can be provided by deposition of the heat treated, "Teflonated" active carbon on a filter paper or like medium containing a bed of soluble salt. 
     The three-layer laminated electrodes of this invention are suitable for use as oxygen (air) cathodes in chlor-alkali and other electrochemical cells, fuel cells and in other electrochemical applications. 
     These three-layer laminates include an active layer or sheet containing from about 60 to about 85 weight % active carbon, the remainder being unsintered, fibrillated polytetrafluoroethylene in intimate admixture with said active carbon, said active layer being laminated on its working surface to a current distributor and on its opposite surface to a porous, coherent, hydrophobic polytetrafluoroethylene-containing wetproofing layer.

Abstract: An externally threaded split end fitting having a surface serving as a camming surface for an end-mounted nut. By advancing the nut along the split end of the fitting the camming surface reacting upon the nut causes a transmission of a reactive force through the nut onto the external threads of the split segmented end of the fitting causing in turn a radially inward bending of the jaw-like segments of the split head. The longitudinal axis of the fitting has a passageway for receiving one or more work pieces, whereby the pivoting of the segments clamp the workpiece(s) into the fitting. The fitting is unitary.
