Abstract: The present invention describes an extrusion process for manufacturing a glass honeycomb structure having a variety of shapes and sizes depending on its ultimate application. Unlike prior art honeycomb structures made from ceramics, the inventive glass honeycomb can be readily viscously bent and/or redrawn. Furthermore, the inventive honeycomb structure is lightweight, yet able to support heavy loads on its end faces. Therefore, the inventive honeycomb can be used as a light-weight support for such objects as mirrors. These honeycombs can be used singularly or in aggregates to provide such support. Embodiments are described wherein the mass of the honeycomb is further reduced by removing select portions of the honeycomb without deleteriously impacting its ability for load bearing.

Abstract: A compact fluorescent lamp in the shape of a conventional light bulb. The exterior and interior surfaces of the lamp are formed by the front and back surfaces of an envelope which defines a cavity whose surface is coated with phosphor. There is a gas discharge channel having at least two electrodes, is located within the cavity for receiving a discharge or ionizable gas. A ballast housed in the cavity is electrically connected to the two electrodes, and when connected to a screw-base, the base is in electrical contact with the ballast.

Abstract: This light scattering technique for size measurement is based on the fact that an illuminated particle (inclusion) serves as a secondary radiation source in a manner which is related to its size. This technique allows for detection of inclusions in the interior of transparent solid media, such as bulk glass. When illuminated with a beam of monochromatic light such as a laser beam as the primary light source, the angular distribution of the scattered intensity originated from the inclusion in the micron to submicron range, is a function of intensity, wavelength and index of refraction. A lens and light trap block the primary light for reaching a detector. The light trap, however, allows the secondary scattered light to reach the detector.

Abstract: This discharge lighting device is directed to a high efficiency, long-life neon discharge lamp with a unique channel configuration.

Abstract: This colloidal silica soot is a byproduct of chemical vapor deposition processing of fused silica or ultra low expansion glasses in the finishing industry. The colloidal silica by product is referred to as "soot". Retaining the same physical properties as the parent glass and having a spherical morphology, the colloidal silica soot is an ideal candidate for polishing applications. The soot has a large particle size when compared to conventional colloidal or fumed silica. As a result, the large size produces less surface damage and allows for a higher (faster) removal rate. The large particle size also results in super polished surfaces.

Abstract: An adjustable stand is disclosed for raising and lowering a cantilevered load while reducing friction and preventing binding in the raising and lowering mechanism.

In addition, an air clamp is provided for lockably positioning the cantilevered load in a desired rotational orientation with respect to the cantilever arm.

The apparatus includes a carriage (26) which is urged along the purlins (18) of the roof structure (11). A roll of insulation material (43) is mounted to the carriage (26) and dispenses a substantially continuous sheet of blanket insulation material (39) over the purlins (18) as the carriage (26) is progressively moved along the length of the purlins (18). A radiant barrier dispenser (70) dispenses a layer of radiant barrier material (72) over the dispensed blanket insulation material (39), and a cross-wise layer of insulation (86) is applied across the length of the purlins (18) in a direction normal to the direction of application of the blanket .insulation material (39). Thereafter, sheets of hard metal roofing material (24) are attached to the purlins (18) over the cross insulation (86) to form the insulated roof structure (11).
