Abstract: A sheet molding composition is disclosed which includes a four component resinous system which comprises (a) an unsaturated polyester comprising a polycondensation product of one or more dihydric alcohols and one or more ethylenically unsaturated polycarboxylic acids; (b) one or more low-profile additives which are thermoplastic polymers which cause phase separation and porosity during the curing reaction; (c) one or more olefinically unsaturated monomers which copolymerize with the unsaturated polyester; and, (d) one or more compatible components comprising at least one compound containing one or more ether substituents. The compatible component is compatible with the reacted unsaturated polyester and monomer during cure and imparts improved surface characteristics when added to low-profile resin systems.

A substrate is heated, and organocupric powder is sprayed at the substrate, using oxygen gas as the carrier gas. Up to one-third greater deposition rate results, as compared to the process using compressed air as the carrier gas.

Abstract: This invention is directed to a process for forming coatings comprising light metal fluorides on a substrate. More particularly, the coating comprising light metal fluorides is preferably made using sol-gel techniques and may comprise a concentration gradient of the light metal fluorides across the thickness of the coating to provide it with unique anti-reflective properties.

Abstract: An accumulator for use with a vehicle air conditioning system is provided. The accumulator comprises a housing having first and second sections, an outlet tube, and an outlet tube shield. Inlet and outlet openings are formed in the housing through which refrigerant enters and exits the interior chamber defined by the housing. The outlet tube extends to the outlet opening and is preferably integral with the second section. The outlet tube shield is integral with the first section and extends into the interior chamber between the inlet opening and the outlet tube to prevent the direct passage of liquid refrigerant into the outlet tube. A desiccant container is preferably provided in the housing to dry the refrigerant as it circulates through the accumulator.

Abstract: A compliant device for a scroll-type fluid compressor including a drive shaft having an axis of rotation. A disk shaped rotor is affixed at one end of the drive shaft and includes a drive pin extending from the side of the rotor opposite the drive shaft. The drive pin 13 disposed at a location eccentric to the axis of rotation of the drive shaft and includes at least one external spline extending therefrom. The scroll-type fluid compressor includes a bushing having an axis of revolution and an orbiting fluid displacement member which is movable in cooperating relationship with the bushing. The bushing has an aperture adapted to receive the drive pin including at least one internal spline mating with the external spline of the drive pin. Clearances defined between the external spline and the internal spline allow displacement of the disk shaped rotor in relation to the bushing upon rotation of the drive shaft.

Abstract: Three-layer, low color purity, anti-reflection coatings reduce the reflection of visible light rays and display a low color purity when glazings carrying such coatings are oriented at high angles of incidence with respect to a source of visible light. The reflectances are comparable and the color purity values are lower for such glazings, when compared with conventional glazings coated with 1/4-178 -174 wavelength anti-reflection coatings.

Abstract: An accumulator is provided for use with a vehicle air conditioning system. The accumulator comprises a housing having first and second sections, an outlet tube integral with the second section, and a desiccant container. Inlet and outlet openings are formed in the housing through which refrigerant enters and exits the interior chamber defined by the housing. The outlet tube extends from the outlet opening into the interior chamber and terminates in a free end. The desiccant container is mounted in the interior chamber between the housing and the free end of the outlet tube to define a first path between the housing and the desiccant container through which incoming refrigerant may flow. The desiccant container also has a second path therethrough through which incoming refrigerant may flow.

Abstract: The present invention relates to a method for inhibiting significant oxidation of a film on a substrate during heating of the substrate. The method includes providing a metal or metal oxide film on a substrate and providing a material adjacent to the film. The substrate is then heated to a temperature sufficient to cause the substrate to bend and the material adjacent to the film reacts in such a way as to protect the metal or metal oxide film on the substrate from further significantly oxidizing.

Abstract: An accumulator is provided for use with a vehicle air conditioning system. The accumulator comprises a housing, an inlet tube, an outlet tube, and an outlet tube shield. The housing includes first and second end portions and a cylindrical body portion which are joined together to define an interior chamber. An inlet opening is provided through which refrigerant in an inlet tube enters the interior chamber. The inlet tube directs the incoming flow of refrigerant against the first end portion of the housing. The outlet tube shield is attached to the inlet tube, and prevents the direct passage of refrigerant between the inlet tube and free end of the outlet tube.

Abstract: A glass treating apparatus suitable for heating glass sheets, such as in a process of forming motor vehicle windshields, comprises a heater suppoted by a modular support structure. The heater comprises a non-monoplanar heating surface subdivided into heating zones. The heating zones are individually controlled. The heating surface can approximate the configuration of the glass sheet. The invention allows preferential heating of selected zones of the glass sheet. One or more such modular radiant heater assemblies can be used in a glass forming process.

Abstract: An anti-reflective coating employing silicon as a high refractive index material in a film pair together with silicon dioxide as a low refractive index material is found to be substantially transparent to visible light and to provide good anti-reflectance where the silicon film is ultra-thin, preferably less than about 50 Angstroms and the thickness of the silicon dioxide film is matched to that of the silicon film. Laminated glazing units having such anti-reflective film can be used, for example, even in applications requiring high transmittance of visible light, such as motor vehicle windshields, in view of the substantial transparency of the coating.

Abstract: A glazing article comprises a substrate bearing a substantially transparent coating comprising an optically functional layer and a thinner anti-iridescence layer undercoat mediate the optically functional layer and the substrate. The anti-iridescence layer eliminates or substantially reduces iridescence and, in addition, is readily designed to make the overall coating colorless or to provide a substantially uniform, muted color. The anti-iridescence layer comprises a high refractive index zone on the substrate, having a refractive index higher than that of the substrate. Multiple gradient step zones are stacked on the high refractive index zone, including a low refractive index zone. A second gradient step zone having a refractive index higher than that of the first gradient step zone is positioned on the low refractive index zone, such that the low refractive index zone is directly sandwiched between the two higher refractive index zones.
