Abstract: Provided is an aerosol method, and accompanying apparatus, for preparing powdered products of a variety of materials involving the use of an ultrasonic aerosol generator (106) including a plurality of ultrasonic transducers (120) underlying and ultrasonically energizing a reservoir of liquid feed (102) which forms droplets of the aerosol. Carrier gas (104) is delivered to different portions of the reservoir by a plurality of gas delivery ports (136) delivering gas from a gas delivery system. The aerosol is pyrolyzed to form particles, which are then cooled and collected. The invention also provides powders made by the method and devices made using the powders.

Abstract: This invention provides certain polycarbonates and polycarbonate blends useful in optical article applications. In a preferred embodiment, copolymers of, for example, certain ortho substituted bisphenol A-based polycarbonates and bisphenol A, optionally further comprising polycarbonate residues derived from ortho subsitituted spirobiindane compounds and alkylene or cycloalkylene diacid moieties. In a further embodiment, the invention provides copolymers of certain ortho-substituted bisphenol A moieties and ortho-substituted spirobiindane moieties. Also provided are optical articles comprised of the copolymers and blends of the invention. We have found that such copolymers and blends exhibit superior dimensional stability when exposed to water or moisture.

Abstract: Aliphatic tricarboxylic acids, as exemplified by 9-carboxy-1,18-octadecanedioic acid, may be prepared by the biotransformation of an olefinic monocarboxylic acid such as oleic acid to the corresponding olefinic dicarboxylic acid, preferably 1,18-octadec-9-enedioic acid, in the presence of a strain of yeast, such as a strain of Candida tropicalis, followed by the carboxylation of the olefinic dicarboxylic acid by reaction with carbon monoxide and water in the presence of a catalyst. The product tricarboxylic acids are useful as branching agents for polycarbonates.

Abstract: The present invention is directed to a report cover combination that includes a slide lock. The slide lock includes a wall defining a channel. Two edges define a slit extending through the wall of the slide lock along its length, and the longitudinal ends of the slide lock are sloped toward the slit to facilitate the insertion of a folded edge of a report cover into the slit of the slide lock. Preferably two parallel lips protrude inward from the edges of the slide lock at the slit. The report cover includes front and back covers having an outer surface. The front and back covers are connected by a hinge. At least one protrusion extends from at least one of the covers adjacent the hinge. The hinge of the report cover is insertable into the channel of the slide lock through the slit. The protrusion is configured and dimensioned to catch against the opposing edges of the slide lock such that the report cover resists extraction from the slide lock.

Abstract: A binder, with a first panel and at least one fastener. The fastener has a base attached to the panel and a binding member positionable in a closed position defining a closed loop, and in an open position in which the loop is open for mounting and dismounting sheets thereto. A lock is disposed in close proximity with the base and in releasable locking association with the binding member in the closed position. A lever is operatively connected with the lock such that depressing the lever in an unlocking direction causes the lock to release the binding member from the closed position.
