Abstract: A system and method for enhancing revenue of vehicle dealerships by increasing both the number of service appointments made by customers at the dealership as well as the number of those appointments which are kept by customers. A computer automated, Internet-based method is provided for supervising the appointment making and the service providing process at vehicle service locations. Service department activity at multiple service locations maintained by a single dealership or by multiple dealerships can be monitored so that material and labor resources can be efficiently allocated and managed between the multiple locations.

Abstract: Vitrified bonded abrasive bodies prepared from sol gel sintered aluminous grit particles and a vitreous (glass) bond exhibit improved abrasive performance by treating the surfaces of the grit particles so as to give them silica-enriched surfaces.

Abstract: A grinding wheel is disclosed which is made up of sintered aluminous abrasive and a vitrified bond, the vitrified bond being a frit. A large portion of the sintered aluminous abrasive may be replaced by a non-sintered abrasive and the bond may include fillers and/or grinding aids.

Abstract: A method for making grinding wheels having an annular grinding section mounted on a central hub in which a slurry of abrasive particles and ceramic bond is coated on a pre-formed core, shaped, and fired. Method has particular advantage in formation of wide wheels and contoured wheels. Premium abrasive may be employed in the wheels.
