Abstract: A flexible sensor assembly for detecting optical pulses in which said sensor assembly comprises a flexible printed circuit having mounted thereon at least one light emitting diode and at least one photoelectric detector connected to different circuit patterns with an insulative tape secured over the circuit and components and wherein the flexible sensor is adapted to be folded so that the photoelectric detector can be spaced from and disposed over the light emitting diode.

Abstract: The present invention provides a new and improved titanium metal drum cathode for use in the production of metal foils and a novel method of making the same. The method includes the steps of welding together the ends of a strip of titanium that has been roll formed into a cylinder. During the welding operation some of the weld beads that form the weld are hot peened immediately upon solidification. Upon complete formation of the weld, the formed and welded trip of titanium is subjected to a heat treating cycle that includes a double anneal. Preferably, the strip of titanium metal and the weld metal that is used to form the weld both comprise an addition agent such as yttria.

Abstract: The present invention relates to a process for making copper foil from copper-bearing material comprising:(A) contacting said copper-bearing material with an effective amount of at least one aqueous leaching solution to dissolve copper ions into said leaching solution and form a copper-rich aqueous leaching solution;(B) contacting said copper-rich aqueous leaching solution with an effective amount of at least one water-insoluble extractant to transfer copper ions from said copper-rich aqueous leaching solution to said extractant to form a copper-rich extractant and a copper-depleted aqueous leaching solution;(C) separating said copper-rich extractant from said copper-depleted aqueous leaching solution;(D) contacting said copper-rich extractant with an effective amount of at least one aqueous stripping solution to transfer copper ions from said extractant to said stripping solution to form a copper-rich stripping solution and a copper-depleted extractant;(E) separating said copper-rich stripping solution from

Abstract: A solid electrolyte cell and method for producing it in which the cell components are assembled within a ceramic frame which is closed on the top by a first terminal of the cell using a solder seal and closed on the bottom by a second terminal of the cell using a solder seal and said second terminal having the opposite polarity to that of the first terminal.

Abstract: A time delay fuse including a fuse casing, terminals located on the exterior of the casing, a hollow electrically insulated inner core having first and second holes in the walls thereof, a fusible element that makes electrical connection to the terminals and is disposed on the surface of the core such that the length of the element is greater than the distance between the terminals, the element passing through the holes, and a material that is deposited on a portion of the element passing through the interior of the core and lowers the melting temperature of that portion.

Abstract: A fuse that includes an insulating housing made from two housing pieces made of thermoplastic material, terminals extending through slots in the ends of the housing, and a fusible element having ends connected to both of the terminals. The housing includes a tubular portion and slotted end portions located at each of the two ends of the tubular portion. Each of the terminals has an internal portion inside the housing to which a fusible element is attached, an external portion outside of the housing, and a middle portion between the internal and external portions and located within one of the slots.

Abstract: A broadband optical fiber coupler comprising at least three continuous optical fibers fused at a region of coupling, at least one of the continuous optical fibers being dissimilar to others of the continuous optical fibers in the region of coupling, the region of coupling being of a length and the dissimilarity being of a degree to provide broadband response over a predetermined range of wavelengths. A related method for making a broadband optical fiber coupler is also disclosed.

Abstract: A fuse including a tubular casing, first and second blade-shaped terminals extending from respective sides of the casing, a short circuit fusible element attached to the first terminal, a heater attached to the second terminal, and a time delay overcurrent trigger mechanism electrically connecting the fusible element and the heater to each other in series in an electrical path between the blade-shaped terminals, the mechanism being connected to receive heat from the heater and to mechanically interrupt the electrical path when the heater heats up under low overcurrent conditions.

Abstract: A solid electrolyte cell and method for producing it in which the cell components are assembled within a ceramic frame which is closed on the top by a first terminal laser welded to the frame, and closed on the bottom by a second terminal laser welded to the frame and said second terminal having the opposite polarity to that of the first terminal.

Abstract: This invention relates to a method for increasing oxidation protection and decreasing the nonuniformities in an electrodeposited layer of a treated copper foil or treated copper-based alloy foil, comprising depositing a protective anti-oxidation coating onto at least one surface of said foil from a solution comprising arsenic. The invention also encompasses the copper foil or copper-based alloy foil coated to improve appearance and oxidation resistance of the foil.

Abstract: An easily peelable or chemically strippable laminate and method of making same comprising an aluminum carrier, an aluminum oxide layer, which is at least 800 Angstroms thick and deposited on the aluminum carrier, copper foil electrodeposited on the aluminum oxide layer and optionally, a brass layer electrodeposited on the copper foil have been discovered. Such laminates find utility in the electronics industry in the fabrication of printed circuit boards and afford an ease of strippability of the protective aluminum carrier-aluminum oxide layer heretofore unknown in the industry. The protective aluminum carrier-aluminum oxide layer of the laminates of the present invention may also be chemically etched away providing a universal carrier for copper foil.

Abstract: An externally mounted blown fuse indicator including a housing, a spring-biased plunger, a tungsten restraining wire, two terminals, and a cover, the plunger having a meltable region that is heated by the restraining wire and melts to release the plunger when the fuse blows, the spring engaging a midsection of the plunger, the housing carrying tabs at its ends for engagement with a switch to be activated by the plunger, the spring-biased plunger having greater than 3 ounces force at an extension of 0.11".

Abstract: A solid electrolyte cell and method for producing it in which the cell components are assembled within a ceramic frame which is sealed on the top to a first terminal of the cell using an adhesive and sealed on the bottom to a second terminal of the cell using an adhesive and said second terminal having the opposite polarity to that of the first terminal.
