Title: Cpds. for radiation therapy or diagnostics contg. Mossbauer nuclides - esp. ruthenium or iron in isotopically enriched form in metallocene or half-sandwich-carbonyl complexes
Inventor: WENZEL MARTIN PROF DR
IPC: A61K51/04
Filed: 1990-05-05
Abstract: Cpds. (II) for radiation therapy or diagnostics contg. Mossbauer absorbing nuclides (I), either in natural isotopic ratios or in enriched form, are new. (I) is an element from transition gps. VII or VIII, esp. Ru or Fe. (II) are esp. metallocene or half-sandwich-carbonyl complexes, which may be bound e.g. to mono- or polyclonal antibodies, esp. those against tumour antigens. USE/ADVANTAGE - (II) contain Fe enriched with 57Fe (most suitable for therapy) or contain Ru enriched with 99Ru (most suitable for diagnostics). The cpds. are stable so metal ion exchange does not take place and they are usually hydrophobic, so they are not readily removed from the body. Some (II) have high affinity for certain organs. Thus ferrocenyl-glycine has affinity for the kidney and 1-ferrocenyl-2-amino-propane and its N-alkyl derivs. have high affinity for the brain.  Excitement of e.g. a 57Fe atom in an organ with gamma-rays causes a localised Auger cascade and a very high localised radiation effect.

The individual consumption of heating power is calculated from the temp. measurers (21,22) as well as the measuring appts for the external temp. The latter is also taken into account for the adiitional charge incurred by having a window open. The room-specific value (27) is formed in a central measuring station (26) form the valves ascertained by the temp measurers. USE/ADVATNAGE - Suitable for single pipe heating circulation system. Avoids incorrect billing.
Patent DE-4018528-A1 (DE)
IPC: B65D83/16
Filed: 1990-06-09
Abstract: The invention pertains to a liner made of elastic, deformable, flexible material. By the special design of the contours in the area of its opening, shoulder, sides, and its bottom, the liner is intended to be so firmly attached to a top, that the assembled components can be handled, stored, and transported as a single unit. The liner, by its quality and form is, by vacuum, completely contracted in the moment of its pneumatic attachment and will be fixed at the top and oriented to its intended resulting shape and direction. Such a liner is used in connection with the manufacturing of a valve liner unit which is intended to be used in a pressurized container. With this valve liner unit, it is possible to easily manufacture a pressurized container by a method according to which the container is first pre-pressurized with compressed air or other compressed gases, while the filling goods make no contact with the inner walls of the container and whereby it is not necessary to create an additional opening to the container instead of the one opening for inserting the valve liner unit. The filling goods can be introduced into the pre-pressurized container according to this method without contact with environmental air.
