Abstract: A mechanism for positionally restraining a microplate is disclosed. The mechanism is defined by a base having at least one surface with a receptacle for the insertion of a microplate into the base. Supports and/or positioning structures on a surface of the base have point contacts to restrain movement of the microplate in a stable position for repeatable optical detection measurements. The supports and/or positioning structures permit insertion of the microplate for an initial measurement, removal of the microplate for analytical manipulation, and re-insertion of the microplate to an exact position so as to allow analysis of precise comparative measurements by an optical reader.

Abstract: A pull roll assembly is described herein that is used to draw a glass sheet. The pull roll assembly includes a first roll assembly, a second roll assembly and a device (e.g., differential drive, sensor(s)). The device enables one to control the first and/or second roll assemblies based in part on pulling forces (e.g., glass contact normal force and/or required sheet pulling force) associated with a glass sheet while the glass sheet is being drawn between the first and second roll assemblies. A glass manufacturing system and method for using the pull roll assembly are also described herein.

Abstract: A high speed high resolution solid film measuring apparatus and method uses coherent monochromatic light by passing the coherent monochromatic light through the solid film and referencing the degree of absorption to known or on-line measured reference values. The measuring apparatus and method accounts for difference in clarity and translucency to derive a running analysis of the solid film thickness. Resolution and speed of the measuring apparatus provides for the adaptation of the measuring device to on-line manufacturing systems as part of a feedback control loop through the manufacturing process.
