Title: Iron-polysaccharide complexes - for parenteral treatment - of iron deficiency anaemia
IPC: A61K33/26
Filed: 1970-05-21
Abstract: Complexes are produced by polymerising a mono- or oligosaccharide, with or without acidic catalysis, to a mixture of polymers of different mol.wt., heating the mixture with aqs. alkali and separating into two or more fractions according to mol. wt., selecting from these fractions a polysaccharide with a specified mol. wt. range, and reacting this with a water-soluble inorganic iron cpd. to give a non-toxic complex.

Title: Lanthanide single-crystal anticancer agent - produced by macerating lanthanide single crystals and converting into suspensions
Inventor: SCHULTE KURT DR
IPC: A61K33/00
Filed: 1973-05-19
Abstract: Production of an anticancer agent based on lanthanides (esp. oxides of lanthanides) comprises (a) growing a single crystal of lanthanides (esp. oxides of lanthanides or mixtures of such oxides), (b) macerating the single crystal to a particle size of is not > 7 mu m, and (c) bringing the macerated crystal into an aqueous, physiological suspension. The agent is effective against all kinds of cancer. It is injected into the bloodstream and the cancer tumour is immediately irradiated with relatively soft X-rays. This causes positive quantum energy to be released in the crystals. The energy is transferred to the negatively charged tumour, causing the potential drop across the tumour cell membrane to return to normal, so that the tumour cells are converted back into normal cells. Thus, unlike conventional anticancer treatment, the new treatment converts cancer cells into normal cells rather than destroying them.

Title: Sludge removal from metal treatment baths - using conveyor belt travelling along bottom of tank
Inventor: WASSEN JOHANN
IPC: C23G3/00
Filed: 1973-10-22
Abstract: This process removes the sediment from baths used for the surface treatment of metals, and consists of passing sheet or strip over rolls so that it covers the entire bottom of the tank; the sludge settles on the sheet which is periodically rolled out of the bath so the sludge can be removed. Squeezing rollers are pref. used to remove excess liq. from the sludge as it travels out of the bath. The sheet can be fed down to the bottom of the bath vertically but a gradual slope is used on the exit side so the sludge does not fall off; movement of the sheet or strip can be either periodic or continuous. The sheet can be wound from one roll onto another or an endless belt can be used and a protective grid is pref. located above the sheet. Used esp. in the picli pickling or phosphating of steel. The process avoids expensive filtration and/or periodic stoppages while tanks are cleaned out, i.e. involving labour and cost.
