Abstract: This invention relates to a method for genetically engineering coniferous plants. In particular, this invention relates to a particle-mediated gene transfer method for producing and developing transgenic somatic embryos for plants of the genus Pinus and Pinus interspecies hybrids. This method is well suited for producing transgenic clonal planting stock useful for reforestation.

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.

More particularly, the invention pertains to the use of stabilizer-containing cationic acrylic colloidal dispersion polymer compositions to enhance the ink jet printability of coating formulations.

Abstract: A paper web is smoothened by passing the web through a pre-calender device on a paper machine before the application of a coating. The pre-calender device comprises at least one pair of steel rolls, one of which is heated, and a liquid application device which applies a thin film of water to the surface of the web which contacts the heated roll before the web enters the nip between the rolls. The web is then dried after exiting the nip either by wrapping the heated roll and/or by applying heat externally to the web.

Abstract: Phase change (hot melt) ink compositions for use in a phase change (hot melt) ink jet recording device in which recording is conducted by thermally melting the ink at a temperature above ambient temperature (20° C.) to provide prints that possess high quality images, scratch resistance, abrasion resistance, low-temperature storage stability and flexibility, offset and pick resistance, adhesion, and other desired properties are disclosed to comprise: (a) from about 0.1% to about 30% of one or more colorants; and (b) from about 0.1 to about 99.9% of one or more hybrid polymers. Components other than those listed above may be included in the ink compositions to achieve specific printer, substrate, or end use requirements.

Abstract: The present invention discloses an improved paperboard for use in food or non-food products. The disclosed board utilizes a novel method of applying adsorptive material to packaging paperboard to overcome emissions (by adsorption thereof) of odiferous manufacturing components from the board, as well as any offensive odors emitted by contents of packages made from the board. The disclosed approach utilizes known adsorptive materials, which are applied to the pulp stock in such a manner that it does not negatively impact either the appearance or physical attributes of the finished board.

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: The disclosed invention is a dimensionally stable laminate prepared by layering resin saturable sheets, treating the layered sheets with a polymeric resin, pressing the treated layered sheets together under high pressure and high temperature to form a laminate and then subjecting the newly manufactured laminate to high humidity (greater than 65%) at relatively low temperatures (32°-45° C.) before exposure to ambient conditions.
