Abstract: PCT No. PCT/DE88/00729 Sec. 371 Date Aug. 15, 1989 Sec. 102(e) Date Aug. 15, 1989 PCT Filed Nov. 25, 1988 PCT Pub. No. WO89/05388 PCT Pub. Date Jun. 15, 1989.A furniture hinge has a hinge arm connectible to the body of a piece of furniture and a lever connectible to a closure for the furniture. The closure is movable between a closed position and an open position. A damping device is disposed between the hinge arm and the lever and includes a housing having a bellows-like first part and a second part secured to the hinge arm. A piston rides in the housing and divides it into first and second chambers. The piston is provided with flow channels which allow hydraulic fluid in the housing to flow between the first and second chambers. The piston is mounted on a rod which extends through, and is coupled to, the first housing part and is articulately connected to the lever. A sealing member likewise mounted on the rod is arranged to seal the flow channels upon movement of the closure to its closed position. As the closure moves to its open position, the rod moves out of the housing with an accompanying expansion of the first housing part and unblocking of the flow channels. The pressure in the first chamber is reduced so that the fluid enters this chamber via the flow channels. Upon movement of the closure to its closed position, the rod moves into the housing and the flow channels are sealed. Fluid then flows from the first chamber to the second chamber by leakage. This may be accomplished by providing the sealing member with a slit and making the second housing part or the sealing member elastically deformable. Alternatively, the piston may be formed with an elastically deformable sealing lip which engages the inner surface of the housing.

Abstract: A method for the removal and concentration of desired ions from a source solution which may contain larger concentrations of other ions including H+ comprises bringing the source solution into contact with a compound comprising a polytetraalkylammonium and/or polytrialkylamine containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The polytetraalkylammonium and/or polytrialkylamine portion(s) of the compound has an affinity far the desired ions to forma complex thereby removing the desired ions from the source solution. The desired ions are removed from the compound by contacting the compound with a much smaller volume of a receiving Solution having a greater affinity for the desired ions than does the polytetraalkylammonium and/or polytri-alkyiamine ligand portion of the compound. The concentrated ions thus removed may be recovered by known methods. The process is useful in removing desired or unwanted ions from water streams and in the treatment of waste streams. The invention is also drawn to the polytetraalkylammonium and polytrialkylamine containing ligands covalently bonded through a spacer grouping to a hydrophilic inorganic solid support material.
