Abstract: A water-resistant porcelain enamel coating and method of making the same is provided. The porcelain enamel coating is prepared using a borosilicate glass frit, and mill additions of silica and a zirconia compound. The mixture is applied to a metal substrate and fired, resulting in a water-resistant coating that resists cracking and crazing. The coating is particularly useful in water heaters. In one embodiment, the coating comprises a fine zirconia compound having a median particle size of less than 10 microns.

Abstract: In a system for managing admissions into parks and attractions, a guest requests reservations via a kiosk unit or purchases advanced ticket attraction packages via the World Wide Web/Internet or through the phone. Once the reservations or purchase has been made, the confirmed reservation is printed onto a confirmation ticket or guest card and the data is uploaded into the system. The guest can then take their confirmation ticket or guest card at the appointed time and gain entry into the attraction through a barrier controlled by the controller unit. The controller unit reads or scans the guest card and allows guests with advance reservations to gain entry without waiting in long lines. In an alternative park operation system, admission to the park is permitted only with advance reservations. As part of the advance reservation, each guest is assigned to a menu group, with each menu group provided with assigned times for each attraction in the park.

Abstract: An anti-microbial porcelain enamel coating and a method of preparing the coating is provided. The porcelain enamel coating contains an anti-microbial agent having an anti-microbial metal compound such as silver, zinc, or copper disposed on a particulate support. The resulting porcelain enamel coating can be used, for example, as a coating over steel for those appliances and sanitary ware fixtures that could benefit from an increased level of resistance to microbes, mold, bacteria, and fungus.
