Disclosed are glass materials generally belonging to the P2O5—ZnO—TeO2 system and process for making the same. The glass may comprise Bi2O3 as well. The high refractive index and low Tg materials are particularly suitable for refractive lens elements for use in portable optical devices. The process involves the use of P2O5 source materials with reduced amounts of reducing agents or a step of removing the reducing agents from such source materials by an oxidizing step such as calcination.

Sodium containing aluminosilicate and boroaluminosilicate glasses are described herein. The glasses can be used as substrates or superstrates for photovoltaic devices, for example, thin film photovoltaic devices such as CIGS photovoltaic devices. These glasses can be characterized as having strain points ≧535° C., for example, ≧570° C., thermal expansion coefficients of from 8 to 9 ppm/° C., as well as liquidus viscosities in excess of 50,000 poise. As such they are ideally suited for being formed into sheet by the fusion process.

The disclosure teaches methods of forming at least one bump in a glass substrate having a surface and a body portion. The method includes performing a first irradiation of a portion of the glass substrate to form in the glass surface the at least one bump having bump height. The method also includes performing thermal annealing of at least a portion of the glass substrate that includes the first irradiated portion. The method then includes performing a second irradiation of the bump to increase the bump height.

The invention relates to a food product dispenser that includes a food delivery mechanism and a cleansing mechanism. The food delivery mechanism includes a food source, a food conduit associated with the food source for receiving a food component therefrom, and a dispensing mechanism configured to dispense servings of the food component from the conduit. The cleansing mechanism includes a cleansing conduit associated with the food delivery mechanism to direct a cleansing fluid along a fluid path in cleansing association with the food delivery mechanism under conditions for performing a cleansing operation on the food delivery mechanism. A controller can be provided for automatically conducting cleansing operations based on predetermined conditions. The controller, delivery mechanism and cleansing mechanism can be configured to switch between the dispensing of the servings and the cleansing operation at a plurality of intervals during a day without substantial intervention from an operator.
