Abstract: The present invention relates to novel chromatography stationary phases comprising non-polysaccharide carbohydrate polyethers and methods for their preparation. Particularly, the invention relates to chromatography stationary phases comprising said carbohydrate polyethers and more particularly to chiral stationary phases. Also, since the carbohydrate polyethers of the present invention can be conveniently prepared with controlled functionality, molecular weights and polydispersity indices as well as controlled microstructure, tertiary structure stationary phases prepared from these polymers can be conveniently modified or custom synthesized to accommodate specific separation requirements.

Abstract: A billfold or pocket wallet for carrying paper money, credit cards, identification cards and the like comprising means to carry a paper notepad and a writing utensil integrated therein. The billfold is constructed to allow for the facile removal of single sheets from the notepad and the billfold is dimensioned to be conveniently carried in a clothing pocket.

Abstract: Disclosed are cooling tubes or straws for beverages and other liquids. The tubes or straws comprise a porous matrix to effect the cooling a liquid contained within by pervaporation.

Abstract: Disclosed are cooling jackets for containers for beverages and other liquids. Such a jacket comprises a porous matrix as an element of the jacket body to effect the cooling of the jacket by pervaporation of a liquid contained within the jacket body. The jacket therefore cools a liquid within a container maintained in direct contact with the jacket.

Abstract: The present invention provides processes for fixation of biological tissue and/or post-fixation treatment of such tissue that result in modified tissues with reduced susceptibility to in vitro calcification when used in prosthetic devices. The invention also relates to calcification resistant biological tissue and to methods of using such tissue.

Abstract: The present invention provides a dispensing apparatus and method for the delivery of remediation agents into waste systems wherein the apparatus is capable of generating and maintaining a controlled release of a concentrated remediation composition throughout the delivery cycle. The invention also provides a dispensing apparatus and methods wherein the remediation agent is a remediation agent that includes living organisms. Finally, the invention provides a waste water remediation dispensing apparatus and method useful in preventing dry trap in drain systems containing U-traps.

The invention also provides a dispensing apparatus and methods wherein the remediation agent is a remediation agent that includes living organisms. Finally, the invention provides a dispensing apparatus and methods wherein compositions of remediation agents are conveniently formulated for specific applications providing a range of retention, activation and release profiles that optimize the remediation effectiveness.

Abstract: Disclosed are self-cooling containers for beverages and other liquids. Such containers comprise porous matrices as elements of the container bodies to effect the cooling of contained liquids by pervaporation. The liquid vapor can pass through the porous matrix directly to the environment or to a collector or trap comprising an absorbent material in contact with the container. Also disclosed are self-cooling containers incorporating insulative sleeves that reduce radiative warming of container surfaces yet permit sufficient pervaporative flux to cool containers residing within such sleeves.
