Abstract: A secured server computer hosting a conventional website, displaying a relational database to participating members that contains identification information pertaining to individuals maintaining an outstanding balance of preferably $150.00, or having a history of delinquent payments with one or more member businesses. The present invention functions to alert small businesses to delinquent customers, as well as to facilitate the resolution of debts between crediting businesses and individual debtors. Automated alerts are enacted through direct mediums such as email, telephone, and conventional postal mail, providing the debtor a chance to dispute accusations, or resolve listed debts prior to being marked as delinquent by the present invention.

Abstract: An exhaust system for fume extraction from a work area such as the vicinity of a welding gun is provided, having an articulted exhaust duct with a fume hood mounted at the forward end thereof. A signal emitter is mounted on the work tool, and three sensors are mounted on the fume hood, one at the front and one at each side so as to form a triangle. One motor is provided at the joint between the front and rear portions of the articulated exhaust duct, and two further motors are provided at the rear end of the exhaust duct. The first motor opens and closes the angle between the front and rear portions of the exhaust duct, and the second motor moves the rear portion of the exhaust duct backward and forward in the same vertical plane as that in which the front and rear portions of the exhaust duct move under the influence of the first motor. The third motor turns the entire assembly in an arc.
