IPC: D21D5/02
Filed: 1993-10-18
Abstract: ABSTRACT      A  rotary  pulp  screening  device  having  a  high efficiency. The screening device includes a rotor having an upper paraboloidal segment surrounded by a cylindrical baffle to split the incoming flow of pulp stock in two unequal parts.  The predominant part flows through a first passage defined between the baffle and the paraboloidal segment of the rotor and is discharged against the screen at an intermediate axial location.  The smallest part of the incoming flow passes between the baffle and the screen and merges with the main stream of the flow when reaching the outlet of the first passage.

Title: Process for the enzymatic preparation of optically active transglycidic acid esters
Inventor: KIERKELS JOANNES G T
IPC: C12P41/00
Filed: 1993-12-16
Abstract: The invention relates to the preparation of an optically active ester of trans-3-phenylglycidic acid in which a mixture of the 2 enantiomers of the trans-3-phenylglycidic acid ester is stereoselectively hydrolyzed using an enzyme originating from Candida antarctica and the non-hydrolyzed eater is separated off from the reaction mixture.      A racemic mixture of trans-phenylglycidic acid esters is selectively and enzymatically hydrolyzed in a relatively short reaction time, the residual ester being obtained in a high yield and with a high e.e. Such esters are used for the preparation of pharmaceuticals such as benzothiazepines and benzazepines.

Title: A system and a process for membrane filtration of a dispersion
Inventor: SAUGMANN AKSEL
IPC: A23C9/142
Filed: 1993-05-03
Abstract: A dispersion having an aqueous continuous phase is membrane filtrated in one or more membrane filtration steps, where a feeding dispersion fed to a filtration membrane is separated in each step into a retentate retained by the filtration membrane and a permeate passing through said filtration membrane, whereby the retentate from one step can be used, if desired, as a feeding dispersion or a portion thereof in one or more succeeding steps. The permeate resulting from one or more steps is subjected to a concentration to form a concentrated fraction containing an increased concentration of the dry matter or a portion thereof present in the permeate, and this concentrated fraction is returned as a portion of the feeding dispersion in one or more membrane filtration steps. A  system for membrane filtration of such dispersion comprises one or more membrane filtration units each associated with a feeding pipe, a retentate exit pipe, and a permeate exit pipe, one or more of the permeate exit pipes (8n-1, 8n, 8n+1, ...) being coupled to one or more concentrating units (10n-1, 10n, 10n+1, ...) adapted to separate the permeate into a diluted fraction and a concentrate, each concentrating unit being provided with an exit (12n-1, 12n, 12n+1, ...) for the diluted fraction and a concentration exit pipe (14n-1, 14n, 14n+1, ...) for the concentrate, said concentration exit pipe being coupled to a return pipe (16n-1, 16n, 16n+1, ...) opening on to one or more of the feeding pipes (2n-1, 2n, 2n+1, ...) of the membrane filtration units.

IPC: F16K1/226
Filed: 1994-11-21
Abstract: Disclosed is a disc valve with a laminated seal ring secured to the housing which forms a leakproof seal with a seating surface on the valve disc.  The seal ring is made of two or more metal laminates, the outer peripheral edges of which are cold welded together, by WIG welding or laser welding, for example, to prevent any leakage of fluid past the opposing, abutting surfaces of the laminations.  A bolt-tightened pressure ring presses the laminated seal ring in an axial direction against an axially oriented support face of the housing. An axially open groove in support face is covered by the proximate seal ring lamination and is filled with a graphite gasket to prevent leakage behind the seal ring.  Alternatively, the laminated seal ring can be mounted on the disc and the cooperating valve seat is formed on the housing.
