Abstract: The method and apparatus relates to the use of a staging conveyor between an initial conveyor and a main conveyor, such as is used for large multiwall or woven packages or bags. The staging conveyor is driven by a servo which is controlled by a programmable logic controller or similar device.

The position of the leading edge is fed back to the programmable logic device which then calculates a desired speed of the staging conveyor in order to present the package or bag to the main conveyor at the desired time. The programmable logic device controls the servo so as to achieve the desired speed.

Abstract: The present invention generally relates to the small-scale separation of a mixture of two or more components with different boiling points into enriched fractions. In some embodiments, a first and second fluid (e.g., a liquid and a gas, a liquid and a liquid, etc.) are passed through a channel. The first fluid may comprise at least two components, each with a unique boiling point. Upon contacting the first and second fluids within the channel, at least a portion of the most volatile of the components in the first fluid (i.e., the component with the lowest boiling point) may be transferred from the first fluid to the second fluid. In some instances, the transfer of the volatile component(s) from the first fluid to the second fluid may be expedited by heating, in some cases above the boiling point(s) of the component(s) to be transferred from the first fluid to the second fluid. Contact between the first and second fluids may be maintained, for example, via segmented flow, bubbling flow, etc.

Abstract: Certain example embodiments of this invention relate to techniques for making a coated article including a transparent conductive indium-tin-oxide (ITO) film supported by a heat treated glass substrate. A substantially sub-oxidized ITO or metallic indium-tin (InSn) film is sputter-deposited onto a glass substrate at room temperature. The glass substrate with the as-deposited film thereon is subjected to elevated temperatures. Thermal tempering or heat strengthening causes the as-deposited film to be transformed into a crystalline transparent conductive ITO film. Advantageously, this may reduce the cost of touch panel assemblies, e.g., because of the higher rates of the ITO deposition in the metallic mode. The cost of touch-panel assemblies may be further reduced through the use of float glass.
