Title: Tumour diagnosis by immunoassay - of antibodies to or antigens of artificially induced microorganisms with tumour affinity e.g. pathogenic clostridium strains
Inventor: WINKLER CUNO PROF DR DR
IPC: G01N33/574
Filed: 1979-10-25
Abstract: In the detection in humans and animals of tumour-indicating antibodies, the antibodies determined are those induced by artificially induced microorganisms which grow in or whose development is promoted by tumours, and the antibody determination is carried out in the blood using radio-, fluorescence- or enzyme-immunological methods. Alternatively, antigenically active microorganisms are themselves determined directly using radioactively labelled antibodies. Used on diagnosis of tumours in humans and animals. The procedure is based on the finding that certain microorganisms, which are detectable by immunological methods, give rise to higher antibody or antigen levels in tumour-bearing animals.

Title: Appts. for conversion of calcium carbide to acetylene - for use in burner or gas engine
Inventor: PRIESEMUTH WOLFGANG
IPC: C10H21/16
Filed: 1980-02-15
Abstract: Process and appts. are claimed for the generation from calcium carbide of acetylene for use in a gas burner or combustion engine. Carbide granules, encapsulated in a water- soluble substance, are fed from their storage vessel to a reaction vessel by an electromagnetic pusher, acting in response to the pressure or amt. of gas in the reaction vessel. Water is fed to this vessel, in excess or in corresp. amt. to the carbide. Acetylene flows on demand to the combustion chambers via a buffer or feed vessel and a suction system. Lime powder or slurry is removed continuously or in slugs. The acetylene generation rate responds quickly to changing demand from the appts. consuming it. Encapsulation suppresses the carbide's smell.
