  • Patent number: 9538843
    Abstract: An item of table furniture has a table top and a table frame supporting the table top. The table top, in plan view, is formed with first pair of opposite edges and a second pair of opposite edges. One edge of the first pair of edges is convex and the other edge of the first pair of edges is concave. The convex curvature and the concave curvature of the first pair of edges has a predetermined first radius of curvature of substantially equal size. One edge of the second pair of edges is longer than the other edge of the second pair of edges. Such a table can be arranged together with items of table furniture of the same kind and also with other items of furniture to an array in many ways.

  • Patent number: 5039649
    Abstract: Anhydrous, solid Raney catalysts in fusible, organic embedding media prepared by initially introducing a Raney catalyst slurry into a vacuum mixer under an inert gas atmosphere, admixing the embedding medium, removing the main quantity of the water at temperatures below the melting point of the embedding medium and removing the residual water above the melting point of the embedding medium in vacuum while maintaining mixing. After the dehydration, the vacuum is terminated by applying an inert gas and the product where called for is shaped into low-surface molded bodies.
