Patent DE-2304846-A1 (DE)
Title: Pseudomonas fluorescens L-lysine oxygenase - for use as a cytostatic against L-lysine-dependent tumours
Inventor: BIERLING ROBERT DR
IPC: A61K38/44
Filed: 1973-02-01
Abstract: L-Lysine oxygenase which catalyses the decarboxylation of L-lysine to 5-amino-valeramide is enriched and purified by fractionally treating a crude extract of a Pseudomonas fluorescens fermentation fraction with protamine sulphate. Pref., a first treatment is used to ppte. impurities, then L-lysine oxygenase is pptd. in pure form from the supernatant by adding further protamine sulphate. L-Lysine oxygenase can be used as a cytostatic agent against lysine-dependent tumours without harming the host organism, even though L-lysine is an essential amino acid.

Title: Device for sepg sperm with Y-chromosomes - having a lamellar system contg. a medium of higher density than sperm
Inventor: NISHINO MITDUKO
IPC: A61K35/52
Filed: 1973-04-19
Abstract: The lamellar system can be e.g. incorporated into a vessel of the type usually used in gynaecology for closing the cervix (e.g. a cap, capsule etc) and may consist of lamellae arranged opposite each other or concertina-fashion. The distance between the lamellae should be such that the high-density medium (which may be e.g. a conventional physiological fluid contg. innocuous density-increasing additives) is prevented by capillary force from flowing out. The new appts. separates out Y-sperm, so that the sex of offspring can be predetermined, e.g. in animal rearing or in human family planning. The appts. can be used in situ, e.g. placed in the cervix of the female animal to be impregnated with the sepd. sperm.

Title: Analysis of trace elements in crystalline materials - using a non-destructive spectrographic system
Inventor: LAGERWEY ANTON ALFRED FERDINAN
IPC: G01N21/64
Filed: 1973-06-27
Abstract: A now destructive method for the analysis of crystals for the presence of trace elements (lanthanides and heavy metals especially) uses a beam of light having a continuous wavelength spectrum of 380-2000 nm (pref. 300-1200 nm) to produce an absorption and a luminescence spectrum in succession. A crystalline substance having a similar lattice and containing known amounts of the elements sought is used for comparison. Opaque and ground or granulated materials are analysed by an absorption spectrum produced by reflected light. Luminescence is produced by excitation with a light beam having a wavelength spectrum of 380-550 nm. Finely ground substances are coated onto an opaque carrier for analysis. Method is useful for the detection of Pr, Nd, Sm, Eu, Tb, Dy, Ho, Er, Tm, Cr and U, for quality control.

Title: Flexible snap fit hinge and joining profiles - with arcuate engaging profiles modified to change joint stiffness
Inventor: NEUMANN GERHARD
IPC: E05D1/04
Filed: 1974-03-13
Abstract: The snap fit hinge or connection is used for connecting panels intended to rotate relative to each other. The connecting profile is moulded integrally into the edge of a flat strip used for fastening purposes. The outer profile consists of a tubular edge section which is partly enclosed by a rib whose cross section is a circular arc. Into the space between these features is pushed a profile whose engaging curved edge cross section deviates from a strictly circular arc. This profile is firmly held in the arcuate gap within the first profile and it allows some rotation. Smoother joints are made if the connection is to act as a hinge. The configuration of the connection determines the force required for its rotation.

Title: Continuous coking process - passing material through tapered gap between endless belts at high temperature
Inventor: OELKERS WOLDEMAR
IPC: C10B7/06
Filed: 1974-07-27
Abstract: Thermoplastics are rapidly softened under compression between two heated endless steel belts with a tapered gap. Organic solids are rapidly and continuously degassed by compressing them (if necessary after reducing and preconsolidating), in a tapered gap between two perforated metal conveyor belts whilst heated externally by coking gases and steam. The material between conveyor belts is heated to low-temp. distn. and carbonizing temp. gases evolved escape through perforations in the belts. Superheated steam is blown in, which prevents the gases from igniting and promotes prodn. of larger oxyhydrocarbon molecules e.g. methanol. The end prod. is a sterile coke which falls onto a separate conveyor.
