Abstract: A hand carried, manually operated apparatus for cleaning flooring, carpet, upholstery, and the like includes a cleansing fluid chamber, a waste fluid chamber, a pump and an applicator. A first fluid passageway connects the pump and cleansing fluid chamber, a second passageway connects the cleansing fluid chamber and applicator, a third passageway connects the applicator and waste fluid chamber, and a fourth passageway connects the waste fluid chamber and pump. A first one-way valve permits flow from the pump to the cleansing fluid chamber but inhibits reverse flow; and a second one-way valve permits flow from the applicator to the waste fluid chamber but inhibits reverse flow. Air is transferred through the pump from the waste fluid chamber to the cleansing fluid chamber as cleansing fluid is transferred to the applicator from the cleansing fluid chamber and waste fluid is transferred from the applicator to the waste fluid chamber.

Abstract: The invention comprises a cross-linkable lyotropic (i.e., surfactant) liquid crystal (LLC) monomer platform that forms type I bicontinuous cubic (QI) polymer networks containing 3-D interconnected nanopores.

Abstract: Presented are systems, apparatuses, articles of manufacture, and methods for identifying information about a particular entity including receiving electronic documents selected based on one or more search terms from a plurality of terms related to the particular entity, determining one or more feature vectors for each received electronic document, where each feature vector is determined based on the associated electronic document, clustering the received electronic documents into a first set of clusters of documents based on the similarity among the determined feature vectors, and determining a rank for each cluster of documents in the first set of clusters of documents based on one or more ranking terms from the plurality of terms related to the particular entity, where the one or more ranking terms contain at least one term from the plurality of terms for the particular entity that is not in the one or more search terms.

Abstract: A collapsible, portable child's play-pen, which may be foldably collapsed onto two half-members which are pivotably coupled together along an axis and which together form a base for the play-pen, which may then be subsequently folded together to form a compact portable unit. First and second frame members, each pivotably coupled to the base along parallel but mutually opposite edges of the base, form one set of opposite side walls of the play-pen. Each of the first and second frame members are provided with a respective pair of first and second pivotable linking arms. One end of each of the first pair of linking arms is pivotably coupled to a first frame member, and similarly one end of each linking arm of the second pair of linking arms is pivotably coupled to the second frame member.
