Patent DE-4032000-A1 (DE)
Title: Pure and technical phosphorus penta:sulphide simultaneous mfr. - using separate reactors for continuously condensed distillate and sump in second stage
Inventor: ZSCHALICH ARNDT DIPL CHEM
IPC: C01B25/14
Filed: 1990-10-09
Abstract: In the simultaneous continuous prodn. of P2S5 (I) of different qualities by reacting pure liquid yellow P with liquid S at temps. above the m.pt. of P2S5, a fluid P sulphide melt (II) with a P content of over 28.2% is formed in a first stage in a small reactor and P2S5 is formed in a second stage by adding S. The novelty is that the second stage is carried out in 2 separate reactors. One reactor is supplied with up to 50% of (II) from the condensation zone of the first steps and reacted with S to (I) of high purity. The other reactor is supplied with the remaining (II) as sump prod. and reacted with S to (I) of technical purity. USE/ADVANTAGE - Costs are reduced, the quality of (I) is better than usual and operational safety is improved. Impurities (organic cpds.) accrue almost exclusively in the sump of the first reactor and affect only the quality of the technical (I), with no disadvantage to the user. The additional plant cost is small. (I) of high purity is used e.g. in the prodn. of insecticides.

Patent DE-4129062-A1 (DE)
Inventor: JONAS ROCHUS DR
IPC: C07B57/00
Filed: 1991-09-02
Abstract: The invention relates to a process for the resolution of enantiomers of 5-heteroaryl-1,3,4-thiadiazinones of formula I by the kinetic resolution of racemates, characterized in that racemic I is dissolved in an inert solvent or solvent mixture and acylated with a chiral acid chloride. The resulting mixture of diastereoisomers is reacted with an amine or alcohol, thereby achieving a complete resolution of one of the diastereoisomers and a very slight or partial resolution of the other diastereoisomer into the enantiomers on which they are based, the resolution products are then separated off and the remaining pure diastereoisomer is converted to the corresponding pure enantiomer by reaction with an amine or an alcohol.
Patent DE-4134246-A1 (DE)
Inventor: SCHABERT HANS-PETER
IPC: G21C19/07
Filed: 1991-10-16
Abstract: For the purpose of interim storage of spent fuel assemblies of a pressurised water reactor or boiling water reactor it is necessary to make the optimum use possible of the storage space present inside a cooling pond. In the case of a storage rack in accordance with the invention, a plurality of rectangular shafts (4) are arranged in the manner of a chess board on a base plate (2), being located diagonally opposite one another in each case. The shafts (4) are connected to one another along their mutually bordering longitudinal edges (42) by at least two connecting elements (20, 26), there being provided at least a first connecting element (20) with a high stiffness in a first direction (30) parallel to the base plate (2), and at least a second connecting element (26) with a high stiffness in a second direction (36) parallel to the base plate (2). A storage rack built up in this way is mechanically stable with respect to transverse forces which act parallel to the base plate, so that an additionally supporting lattice bond is no longer required. As a result, the intermediate positions (5) of the storage rack which are not occupied by shafts (4) can also be loaded with fuel assemblies.

Title: Sludge filter - has closure blocks to be operated for rinsing to clean filter without interrupting the filtration
Inventor: BARTELT BERTRAM
IPC: C02F11/12
Filed: 1993-01-13
Abstract: To filter a liquid, where the filter is cleaned during the filtering action at time intervals, a block leading to a chamber for sludge sepn. is opened and/or closed without interrupting filtration. Also claimed is a filter assembly with a chamber for sludge separation after the filter housing, for the material to drop through by gravity. In pref. embodiments, after the block has been closed, a further block is opened for free rinsing. When the second block is closed, the first block is opened and the sludge is removed by back rinsing. The free rinsing and/or back rinsing uses air and/or other gases which are suitable for drying. A further block is closed at the end of the back rinsing action. A continuous filtration is effected by sensors and/or other controls. USE/ADVANTAGE - The system is for sepn. of sludge for drying. The method gives a continuous filtering action and reduction in the residual moisture content.
