Abstract: The present invention involves bilayers that include cesium tungsten oxide as an infrared absorbing agent. Cesium tungsten oxide can be incorporated into one or more layers of a bilayer. Bilayers of the present invention incorporating cesium tungsten oxide are effective at blocking infrared radiation and, surprisingly, the cesium tungsten oxide agents do not degrade unacceptably over time.

Abstract: The present invention provides a method for continuously washing poly(vinyl butyral) in which a poly(vinyl butyral) slurry is passed through multiple continuous stirred tank reactors, each of which is adjusted to specific processing parameters that allow for continuous input, washing, and removal of poly(vinyl butyral). The resulting poly(vinyl butyral) can then be dried to form a powder resin that can be used in place of conventional poly(vinyl butyral) resin. In an alternative embodiment, a counter current screw washing unit is provided that passes wash water over the poly(vinyl butyral) in a direction opposite to the flow of the poly(vinyl butyral), thereby allowing the continuous washing of the poly(vinyl butyral) resin.

Abstract: There is disclosed herein novel functional fluids useful as aircraft hydraulic fluids comprising at least about 50% trialkyl phosphate ester and at least one aryl compound whereby the fluid exhibits in combination the fire resistant properties as indicated by a fire point in excess of 177° C., a flash point of at least 160° C. and an autoignition temperature of at least 400° C. The trialkyl phosphate esters contain between 6 and 18 carbon atoms and preferably between 12 and 15 carbon atoms. The aryl compounds are most preferably polyphenyls, fused ring aryl compound containing from 5 to 24 carbon atoms in the aryl portion such as biphenyl or terphenyl or alkyl substituted polyphenyls wherein the alkyl groups contain from 1 to 5 carbon atom. Other aryl compounds includes fused ring aryl compounds such as naphthalene, anthracene, diphenyl oxide and the like.

Abstract: This invention is directed to a plastic composite comprising color images printed onto a polymeric support film using UV ink. The polymeric support film layer may be bonded to a polymeric film selected from the group consisting of aliphatic polyurethane and ethyl vinyl acetate. The combined laminate can then optionally be disposed between two layers of plasticized PVB, forming the plastic composite. The plastic composite can then be placed between two sheets of glass forming the final laminated glass product. Preferably, when the UV image is printed on the polymeric support film, the image is only partially cured by a UV lamp. After the polymeric support film is contacted with the polymeric film, with the partially cured UV image therebetween, the laminate is exposed to a second UV lamp operating at full power so as to completely cure the UV image.

Abstract: Glass laminates are prepared using low-water content plastic interlayer material, such as polyvinylbutyral interlayer sheets, by a process employing nip roll de-airing, and high temperature finishing at atmospheric pressure.

Abstract: The process for manufacturing unsaturated mononitriles, such as acrylonitrile and methacrylonitrile, has been modified to add a partially condensed quench effluent stripper column to remove high boiling organic compounds from the reactor effluent prior to introduction into the extractive distillation recovery column. The high boiling organic compounds are preferably removed after the ammonia in the reactor effluent has been neutralized and the neutralization products have been removed. The targeted high boiling organic compounds are associated with fouling in the recovery section of the plant.

Abstract: The present invention discloses an improved spray suppression device for vehicles. One embodiment of the present invention comprises a front panel having generally opposed first and second main surfaces and being configured to have a plurality of first through openings laterally and longitudinally spaced apart from each other, each forming a flow path through the front panel and a plurality of protrusions each having a cap and at least one post, connected to said front panel and positioned to project from the first main surface for substantially facing their leading wheel of the vehicle. Each cap is positioned substantially above at least one said first opening in said front panel and forming a second opening between the first main surface and the cap. The present invention provides a mud flap which allows air to pass through its opening without clogging with mud, rocks, and road debris.

Abstract: This application discloses a high performance hydraulic fluid suitable for use as an aircraft hydraulic fluid comprising a major amount of tri(n-butyl)phosphate, a minor amount of a triaryl phosphate and optionally a minor amount of tri(isobutyl)phosphate. The compositions of this invention provide superior performance with respect to flash and fire points as well as extended useful fluid life in service. Such properties are highly valuable as hydraulic fluids modern jet aircrafts.

Abstract: A process for the ammoxidation of an alcohol feed, such as methanol, or a nitrile feed, such as propionitrile, or a mixture thereof, to form hydrogen cyamide uses a modified Mn—P catalyst having the following empirical formula: MnaP1AbOx where A=one or more of K, Ca, Mo, Zn, Fe or mixtures thereof; a=1 to 1.5; b=0.01 to 1.0 and x is a total number of oxygen atoms determined by the oxidation states of the other elements present.
