Patent DE-4221321-A1 (DE)
Inventor: AKAGIRI KENZO
IPC: G11B27/031
Filed: 1992-06-29
Abstract: Data recorded with bit compression at a constant bit rate on a magneto-optical disc (1) are reproduced and transmitted to an excess bit removal circuit (84) without an expanding operation, so that at least some bits which will give a quantization noise level imperceptible to human ears are removed by bit compression in relatively small blocks resulting from division along both the time axis and the frequency axis before recording the data on an IC card (2). By removing at least a part of the portions of the bit-compressed data which are not heard by human ears, the quantity of data recorded on the IC card (2) may be reduced further. Moreover, high speed dubbing can be achieved because data are transferred in the compressed state. The bit rate of the data bit-compressed by the bit removal is a variable bit rate, Fig. 2, (not shown). <IMAGE>

IPC: C07C45/50
Filed: 1993-05-14
Abstract: Process for the preparation of aldehydes by the hydroformylation of olefins having more than seven carbon atoms, comprising the step of hydroformylation by means of a rhodium catalyst dissolved in homogeneous reaction medium, the separation of the rhodium catalyst from the material discharged from the hydroformylation reaction, and the recycling of the rhodium separated off from the material discharged from the hydroformylation in the hydroformylation step by extracting the rhodium catalyst from the material discharged from the hydroformylation by means of an aqueous solution of a nitrogen-containing complexing agent from the group consisting of pyridines, quinolines, 2,2'-bipyridines, 1,10-phenanthrolines, 2,2'-biquinolines, 2,2',6',2''-terpyridines and porphines which are optionally substituted, sulphonated or carry sulphonated substituents and/or from the group consisting of carboxylated pyridines, carboxylated quinolines, and 2,2'-bipyridines, 1,10-phenanthrolines, 2,2'-biquinolines, 2,2',6',2''-terpyridines and porphines which are optionally substituted, carboxylated or carry carboxylated substituents, in the aqueous phase and feeding back the aqueous, rhodium-containing extract to the hydroformylation step.
Patent DE-4316486-A1 (DE)
Title: Valve
Inventor: MERZ SIEGFRIED
IPC: F16K1/54
Filed: 1993-05-17
Abstract: In the valve according to the invention, an inlet space arranged upstream of a regulating gap is formed in such a way by the shaping of a closing body and/or of a valve seat that different flow velocities arise around the circumference of the regulating gap. The differing velocity of flow is achieved, for example, by virtue of the fact that a valve cone (5) forming a closing body has, upstream of a seating surface (8), a control surface (13) which influences the regulating behaviour and which consists of component surfaces (13a, 13b, 13c) of differing configuration. These measures ensure that whistling noises, which generally occur in certain valve positions, cannot occur. Valves of this kind can be used for preference in systems in which a flow of fluid is being regulated. <IMAGE>
