Patent number: 9914989Abstract: A process by which molten solder is purified in-situ, making the soldering process more efficient and yielding better results, particularly for lead-free soldering. Lead-free solder becomes practical for use since the temperature for reliable soldering is reduced. A layer of active additive is maintained on the surface of molten solder for scavenging metal oxide from the solder and assimilating metal oxide into a liquid layer. The active additive is an organic liquid having nucleophilic and/or electrophilic groups. As an example, a layer of dimer acid maintained on a wave soldering apparatus scavenges metal oxide from the bath, and assimilates dross that may form on the surface. Scavenging metal oxide cleanses the bath and lowers viscosity of the solder, and PC boards or the like soldered on the wave have reliable solder joints.Type: GrantFiled: December 15, 2015Date of Patent: March 13, 2018Assignee: MS2 Technologies, LLCInventors: Lawrence C. Kay, Erik J. Severin, Luis A. Aguirre

Patent number: 7955561Abstract: Chemical sensors for detecting analytes in fluids comprising a plurality of alternating nonconductive regions (comprising a nonconductive material) and conductive regions (comprising a conductive material). In preferred embodiments, the conducting region comprises a nanoparticle. Variability in chemical sensitivity from sensor to sensor is provided by qualitatively or quantitatively varying the composition of the conductive and/or nonconductive regions. An electronic nose for detecting an analyte in a fluid may be constructed by using such arrays in conjunction with an electrical measuring device electrically connected to the conductive elements of each sensor.Type: GrantFiled: April 18, 2005Date of Patent: June 7, 2011Assignee: The California Institute of TechnologyInventors: Nathan S.

Publication number: 20100273022Abstract: Soldering with lead-free alloys is enhanced by use of two additives to a molten solder bath. One additive is an oxygen barrier fluid that floats on or envelops a bath. Another additive is an oxygen or metal oxide scavenger in the bath. Exemplary scavengers include metals with a higher free energy of oxide formation than oxide of tin, reducing gas, or an electrode immersed in the bath. The oxygen barrier may be an organic liquid, preferably polar in nature, which forms at least a monomolecular film over static surfaces of the bath. An exemplary soldering process is wave soldering of printed circuit boards.Type: ApplicationFiled: February 16, 2010Publication date: October 28, 2010Applicant: P. Kay Metal, Inc.Inventor: Erik J.

Patent number: 7593863Abstract: The present invention relates to systems and methods for measuring and testing a product using artificial olfactometry and analytical data sensory to identify preferences. The system accurately facilitates a consumer's choice between products using descriptors of similar yet different products. The system and methods provide an objective recommendation based upon analytical descriptors and attributes of particular products. The system eliminates the subjective recommendations of persons familiar with many comparable and related products and thereby makes objective recommendations between products.Type: GrantFiled: March 9, 2001Date of Patent: September 22, 2009Assignee: Smiths Detection Inc.Inventors: Steven A.
