Patent number: 6319617Abstract: A solder composition that bonds well to oxides and other surfaces to which solder bonding is conventionally difficult is provided. The solder is particularly useful for reliable bonding and packaging of optical components that often have oxide surfaces. The solder composition exhibits a microstructure containing a solder matrix in which is distributed fine, micron-scale islands of rare-earth-containing intermetallic particles. The existence of the islands makes the rare earth elements better available for bonding, and reduce the extent to which the rare earths are oxidized. Advantageously, the solder contains Au and/or Ag, in which the rare earth elements tend to have some solid solubility. Due to this solubility, the Au and/or Ag tend to provide some additional protection of the rare earths against oxidation, and thereby also provide accelerated dissolution of the rare earth into the molten solder.Type: GrantFiled: August 18, 2000Date of Patent: November 20, 2001Assignee: Agere Systems Gaurdian Corp.Inventors: Sungho Jin, Guenther Wilhelm Kammlott, Hareesh Mavoori, Ainissa G Ramirez

Patent number: 4629516Abstract: A process is provided for increasing the strength of antimony-lead alloys by specially treating an alloy which contains an effective amount of arsenic in the alloy, the process comprising working the alloy, rapidly heat treating the alloy, which includes quenching, for a period of time sufficient to activiate a strengthening mechanism in the alloy. The process is especially useful for the manufacture of battery grids on a continuous production line.Type: GrantFiled: April 1, 1985Date of Patent: December 16, 1986Assignee: ASARCO IncorporatedInventor: Michael Myers

Patent number: 4491679Abstract: The disclosed invention includes improved devices and materials for thermoelectric conversion, particularly for operation at temperatures of 300.degree. C. and below. Disordered p-type semiconductor elements incorporate compound adjuvants of silver and lead to achieve enhanced "figure of merit" values and corresponding increased efficiencies of thermoelectric conversion. Similar results are obtained with disordered n-type elements by employing lowered selenium contents, preferably in combination with cuprous bromide.Improved conversion devices include powder pressed elements from one or both of these materials.Type: GrantFiled: July 21, 1983Date of Patent: January 1, 1985Assignee: Energy Conversion Devices, Inc.Inventor: Diane E. Moore

Patent number: 4478919Abstract: A side terminal lead alloy is provided which is a composition of lead, 3 wt-% antimony and 10 wt-% brass. The alloy is capable of use in conjunction with resistance welding techniques. The terminal created thereby exhibits sufficient structural integrity to permit a mechanical connection to be made directly thereto without any additional threaded inserts and exhibits sufficient electrical current conductivity to permit direct electrical connection thereto.Type: GrantFiled: March 31, 1983Date of Patent: October 23, 1984Assignee: Tiegel Manufacturing CompanyInventor: Ralph G. Tiegel

Patent number: 4468415Abstract: An indium-antimony complex crystalline semiconductor consisting essentially of crystals of an indium-antimony compound and crystals of indium alone is disclosed. The atomic ratio of the total indium content to the antimony content in the semiconductor is in the range of from 1.1/1 to 1.7/1. A process for producing such semiconductor is also disclosed. In the process, the vapors of indium and antimony are deposited on a substrate in such a manner that the arrival rate ratio of indium to antimony is controlled to be within the range of from 1.1/1 to 1.7/1.Type: GrantFiled: March 25, 1982Date of Patent: August 28, 1984Assignee: Asahi Kasei Kogyo Kabushiki KaishaInventors: Keiji Kuboyama, Takeki Matsui, Takeo Kimura

Patent number: 4443405Abstract: The grain size and resistance to corrosion of lead-antimony alloys containing less than 4% of antimony and 0.005 to 0.1% copper, are improved by incorporating therein from 0.001 to 0.1% of a mixture of rare earths, preferably misch metal. The alloys may also contain up to 0.5% arsenic or up to 0.8% of tin.Type: GrantFiled: June 30, 1982Date of Patent: April 17, 1984Assignee: Societe Anonyme dite Compagnie Europeene d'AccumulateursInventors: Gerard Dalibard, Nicole Viaud

Patent number: 4427629Abstract: A process for metal-enrichment of lead bullion, wherein an alkali metal-desired metal intermetallic, such as sodium-antimony intermetallic, is added as a refining dross to the bullion and the desired metal is stripped from the dross and recovered as an enriched bullion. The process includes the steps of heating the lead bullion, in which the desired metal is to be recovered, to a temperature between 650.degree. F. and 900.degree. F.; agitating the molten bullion; adding said alkali metal-desired metal intermetallic to said bullion; mixing said intermetallic into said bullion; adding a stripping reagent for stripping said desired metal from said intermetallic; forming a desired metal-enriched lead bullion and a residue dross substantially void of said desired metal; and separating said enriched bullion from said residue dross. The process may also require a cleansing step to cleanse said enriched lead bullion of any said alkali metal in solution.Type: GrantFiled: November 23, 1982Date of Patent: January 24, 1984Assignee: GNB Batteries Inc.Inventors: Jitesh R. Mehta, Andrew H. Larson
