Abstract: Disclosed is a method for sharply reducing diurnal breathing loss emissions from automotive evaporative emissions control systems by providing multiple layers, or stages, of adsorbents. On the fuel source-side of an emissions control system canister, high working capacity carbons are preferred in a first canister (adsorb) region. In subsequent canister region(s) on the vent-side, the preferred adsorbent should exhibit a flat or flattened adsorption isotherm on a volumetric basis and relatively lower capacity for high concentration vapors as compared with the fuel source-side adsorbent. Multiple approaches are described for attaining the preferred properties for the vent-side canister region. One approach is to use a filler and/or voidages as a volumetric diluent for flattening an adsorption isotherm. Another approach is to employ an adsorbent with the desired adsorption isotherm properties and to process it into an appropriate shape or form without necessarily requiring any special provision for dilution.

Abstract: An improvement is disclosed over conventional internal sizing of stock furnish for papermaking, wherein alum is added to the thick paper stock and the long retention time permits complete reaction with the fibers. The invention process permits successfully adding novel aluminum rosinate size composition unconventionally in thin stock furnish, where retention times are on the order of less that 1 minute. The highly charged aluminum rosinate size is able to be quickly adsorbed onto the fiber surfaces to permit surprisingly efficient sizing in thin stock. The quick sizing avoids concern with rising pH over time (in conventional thick stock application) and increases sizing efficiency.

Abstract: This invention concerns cationic core-shell particles having an acid-insoluble polymeric core and an acid-swellable polymeric shell component disposed generally about said core so that upon neutralizing said shell with acid, a portion of said shell remains attached or associated with said core. This invention further concerns polymer latex compositions wherein said polymeric shell component has been neutralized and substantially, but not totally, dissolved so as to form a blend of neutralized core-shell polymer and an aqueous solution of neutralized shell polymer. More particularly, the invention concerns the use of latex compositions produced from these cationic core-shell particles to formulate ink jet receptive coatings.

Abstract: A new shaped activated carbon and the method of its manufacture are disclosed. The invention resides in the crosslinking of a polymeric cellulose, such as sodium carboxymethylcellulose (CMC), within the carbon bodies after they are shaped, employing the CMC as a binder for the activated carbon. The approach to attain product mechanical strength and water stability by crosslinking rather than high temperature heat treatment is not obvious from the prior art teaching. The crosslinking reaction occurs at temperatures below 270° C. In addition, this new binder technology produces shaped carbon bodies having key properties beyond the best level that has been accomplished with other binders.

Abstract: The present invention is directed to a gene and gene product of sweetgum (Liquidambar styraciflua), referred to herein as the LSAG gene, which is a homolog of the AGAMOUS gene. The LSAG gene is a flowering gene which is required for normal flower development and sweetgum fertility. The present invention is also directed to an LSAG promoter and/or enhancer and/or intron which can be used to prepare gene constructs and transgenic plants for tissue specific expression of the gene construct. The gene constructs and transgenic plants are further aspects of the present invention. Finally, the present invention is directed to methods to control flower development and hence assure sterility in transgenic sweetgum.

Abstract: In a tall oil refining operating plant, a warm water loop is disclosed for cooling the tall oil heads fraction extracted from the crude tall oil, rather than the conventional use of cold water. This avoids condensation and the subsequent solidification of athraquinone pulping aid remaining in the crude tall oil; thus, avoiding fouling of the cooling towers. The temperature of the warm-water is controlled automatically by tempering the cold water entering the warm water “cooling” loop, while removing excessively warm water from said loop to the cooling tower system, as needed.
