Abstract: An access floor system comprising (1) block panels made up of one or more panel units, (2) a groove structure defined by adjacent block panels, the groove structure capable of containing wiring, (3) lid panels for covering the groove structure, and (4) central locking plates to cover the spaces remaining at the juncture of lid panels and to lock the assembly together.

Abstract: This invention relates to a correction tape adhesiver for correcting a mistyped letter comprising a rotatable tape guider which may turn its direction according to the gripping posture and/or using direction of the user. Said tape guider is formed separately from the case at the backside edge thereof and combined with the guide sill so as to ensure rotation of the tape guider to the certain extent.

Abstract: An aqueous flux removing composition is provided comprising alkali metal carbonate salts, an alkali metal silicate corrosion inhibitor and a surfactant formulation which comprises an N-alkylpyrrolidone. The N-alkylpyrrolidone is added in amounts sufficient to permit significantly faster cleaning speeds.

Abstract: A frame or rack for creating a compact formation of billiard balls on a table. The interior of the side walls of the frame is angled inward to urge the balls into a compact formation. Sleeves, attached to the frame, house support legs. The relationship between the sleeves and the support legs provides for and controls the motion of the frame and likewise, limits undesired motion of the frame until the frame is clear of the ball formation. The player's effort is limited to pressing down on the frame to compact the ball formation, while springs within the sleeves bias the frame upward. Spring loaded contacts or projections may be housed within the inner walls of the frame to reduce contact between the balls and the frame.

Abstract: A metal cleaning composition useful in an aqueous solution comprises an alkali metal salt and a corrosion inhibitor. The corrosion inhibitor is provided in the form of zinc phosphate compounds such as zinc orthophosphate.

Abstract: The invention relates to a novel, advantageous process for the preparation of liposomes for the inclusion of water-soluble or hydrophilic substances or mixtures of substances, which process provides the surprising advantage, in comparison with known processes, that the proportion of substances or mixtures of substances actually included is increased and which, when used pharmaceutically, provides the advantage of sterile working conditions. In this process, a mixture consisting of at least one phospholipid and customary lipophilic excipients is subjected to a mobile carrier phase consisting of carbon dioxide and a polar organic solvent (modifier) under supercritical pressure and temperature conditions, the compressed mixed phase is reduced to normal pressure and transferred to an aqueous phase comprising a substance having water-soluble or hydrophilic properties for encapsulation in liposomes.
