Title: Post-prodn. treatment of hollow-fibre membranes - by two-stage treatment with mixts. of solvent and non-solvent
Inventor: ALBRECHT WOLFGANG DR
IPC: B01D67/00
Filed: 1990-06-29
Abstract: Post-prodn. treatment of hollow-fibre membranes made of a synthetic polymer (I) is effected by (a) continuously drawing the surface-dried fibres through two treatment baths in succession in an appts. designed so that the fibres do not change direction or contact the walls of the appts., and (b) washing and/or extracting the fibres to remove bath components and any contaminants resulting from the prodn. process. The 1st bath comprises at least 90 wt.% of one or more solvents for (I) and up to 10 wt% of one or more nonsolvents and/or solutes. The 2nd bath comprises up to 50 wt.% of one or more solvents for (I) and at least 50 wt.% of one or more nonsolvents. The temps. of the 1st and 2nd baths are 0-150 and 1-50 deg.C respectively. The residence times in the 1st and 2nd baths are 0.1-120 and 1-300 sec respectively. The time delay between the 1st and 2nd baths is no more than 300 sec. USE/ADVANTAGE - Used to modify the properties of the membranes, e.g. to increase water permeability and reduce separative selectivity. the membranes may be used in technical, medical and biotechnological applications and in the food industry.
Patent DE-4026585-A1 (DE)
Title: Prodn. of non-composted substrate for edible fungi - comprises treatment of organic material, e.g. cereal seeds, with aq. base and neutralisation with carbon di:oxide
Inventor: KYNAST JUERGEN
IPC: A01G1/04
Filed: 1990-08-23
Abstract: Prodn. of a synthetic, non-composted substrate (A) for fungi comprises treating an organic material with a basic, aq. soln. and subsequently neutralising with carbon dioxide. The treatment with the soln. serves to swell, disinfect and chemically modify the organic material and the neutralisation produces a protective layer of carbonate, e.g. calcium carbonate, on the particles of the substrate which inhibits spore germination and bacterial growth,. Material pref. contains protein and starch and is esp. seeds, e.g. of cereals or legumes, or pelleted milling byprods., opt. straw or wood. The organic material is pref. treated at up to 100 deg. C with a base soln. which contains calcium hydroxide. An improved disinfecting effect can be achieved by carrying out the treatment in the presence of an oxidising agent, esp. potassium permanganate, and/or a biocidal gas, esp. propylene oxide. After removing excess base soln., the material can be pasteurised at 70-100 deg. C and treated with substances which regulate pH, mineral content and water-retaining capacity, before finally being neutralised. The latter is achieved using carbon dioxide present in the air or produced after the admixture of spawn of vigorously growing fungi, e.g. Pleurotus spp.. USE/ADVANTAGE - (A) is used esp. for cultivation of edible fungi and for the prodn. of their spores. (A) is obtd. by simple and quick method and in use gives higher yields in shorter cultivation periods than conventional procedures. Further, (A) does not require autoclave sterilisation (unlike the substrate described in DE2151326), is suitable for use with a wide variety of fungi which can be cultivated simultaneously and is not attacked by air-borne spores and bacteria.

In an example, 22(S)-Dihydro-iso-FR520 (100 mg) in toluene, (2 ml) was stirred with p-toluenesulphone acid (5 mg) for 70 hrs., at 60 deg.C. Work up gave 22,26-epoxy-22,26-didehydroxy- 22(S)-dihydro-iso-FR520. In tests on the proliferative response of lymphocytes to allogenic stimulation, (I) were active in concns. of 0.01-10 nm.

Title: Ion beam machining control for lenses - using simulated machining strategy for computer control of aperture system
Inventor: NICKEL ANDREAS
IPC: H01J37/304

Title: New gamma-amino butyric acid permease gene - for growth inhibition of microbial or plant cells or as selectable marker
Inventor: BARTSCH KLAUS DR
IPC: C12N1/21
Filed: 1992-02-12
Abstract: A gene for GABA permease is claimed (GABA = gamma-aminobutyric acid). Also claimed are: (1) GABA permease having a cytotoxic effect on cells in which it is overexpressed; (2) a plasmid contg. the gene; and (3) microorganisms (esp. E. coli), plants, plant cells and seeds contg. the plasmid. USE - Overexpression of the gene in microbial or plant cells may be used to produce cytotoxic effects in microorganisms, plants, plant cells or seeds, e.g. transforming plants with the gene under the control of a pathogen- or wound-inducible promoter produces hypersensitive resistance to pathogen attack, and transforming plants with the gene under the control of an anther-specific promoter may be used to produce male-sterile plants. The gene may also be used as a selectable marker for: (a) detecting plasmids contg. DNA inserts, since cells contg. plasmids with the insert in the GABA permease gene will not be inhibited in growth; and (b) positive selection of integrated DNA fragments in the genome of an organism, by using a cloning vector contg. a selectable DNA fragment and the GABA permease gene, and selecting clones contg. the integrated fragment without episomal or chromosomal copies of the GABA permease gene
