摘要:
A composition for reducing a copper oxide layer to metallic copper so as to facilitate bonding a resin to the metallic copper is disclosed. The composition is an aqueous reducing solution containing a cyclic borane compound. Examples of such cyclic borane compounds include those having nitrogen or sulfur as a ring-forming member, such as morpholine borane, piperidine borane, pyridine borane, piperazine borane, 2,6-Iutidine borane, 4-methylmorpholine borane, and 1,4-oxathiane borane, and also N,N-diethylaniline borane.
摘要:
An improvement in a method of bonding copper and a resin together wherein a copper oxide layer is formed on the surface of copper by the oxidation of metallic copper, the copper oxide layer is reduced to metallic copper with an aqueous reducing solution containing at least one amine borane represented by the general formula: BH3NHRR′ (wherein R and R′ are each a member selected from the group consisting of H, CH3, and CH2CH3), and the metallic copper is bonded to a resin. According to the improvement, a reducing stabilizer is added to the reducing solution in an amount sufficient to decrease consumption of the amine borane during reduction to a level less than that consumed in the absence of the reducing stabilizer during the course of the copper oxide reduction process, wherein the stabilized reduction process is initiated in a reasonable time and the metallic copper layer resulting from the stabilized reduction process is resistant to acid attack. Examples of such reducing stabilizers include thio-containing (—C(═S)NH2) compounds, triazole-containing (C2H3N3) compounds, isoxazole-containing (—C3HNO) compounds, thiazole-containing (—NCS—) compounds, imidazole-containing (—NCN—) compounds, and sulfone-containing (—SO3H) compounds.

摘要:
A method to significantly reduce the need for treating bottom ash with a bonding agent, such as lime or concrete, as is typically done by Waste-to-Energy facilities within the United States of America. Furthermore it is a method that will greatly reduce the costs associated with freight, and disposal typically associated with WTE bottom ash by extracting excess water, metallic, and eliminating the need for supplemental additives such as lime or concrete.

The present invention provides a method and system for scheduling service appointments based on service reminders sent based on the estimated mileage the vehicle. The mileage of the vehicle can be estimated based on the age of the vehicle, or it can be based on the last known mileage of the vehicle and estimating the additional mileage using average vehicle mileage statistics. The mileage of the vehicle may be estimated based on actual vehicle history, and may be adjusted based on the characteristics of the vehicle, the driver, or the geographic location of the vehicle. Service reminders sent to a recipient include a link to a scheduling server. The scheduling server provides a scheduling page allowing the recipient to view and select from available service time slots at the service shop.
