Patent DE-3827810-A1 (DE)
Title: Agglomerated phosphate furnace charge and process for its preparation
Inventor: FINLEY JOSEPH HOWARD
IPC: C01B25/027
Filed: 1988-08-16
Abstract: Calcined, finely divided phosphate, which is obtained as abraded material from agglomerates for the charging of electric furnaces for phosphorus production, is converted into a supplementary furnace charge. For this purpose, the finely divided phosphate is mixed with carbon as reductant (reducing agent), the required amount of silicon dioxide as flux and with phosphoric acid as binder and the mixture is shaped into briquettes which are hardened by heating to a sufficient temperature. Reaction takes place between the acid and the finely divided phosphate, and hardened briquettes of phosphate salts are obtained. The additional charge has a higher content of P2O5 than the main charge and thus makes possible an increased phosphorus yield.

Inventor: KUEBLER ULRICH DR MED
IPC: A61K31/095
Filed: 1990-07-03
Abstract: Thiols of formula RSH can be used to maintain sufficient cell division in vivo and in vitro, even in the presence of cell poisons. (R is not given). The thiol is pref. L-cysteine, or is a thiol in which the SH gp. is Me-substd., (e.g. L-methionine) or a methylsulphonium cpd. (e.g. S-adenosyl-methionine), or a sulphonic acid such as cysteic acid or tuarine. The thiols are modified by ethanoyl gps. and the aminoacid configuration are stabilised by organic salts, e.g. of zinc. The thiols are used to encourage cell growth and regeneration despite the presence of cell growth and regeneration poisons such as halides and hydrocarbons. The thiols can thus be used in the treatment of Alzheimer's disease (Al poisioning) and against poisoning by fluorine and Paraquet, Dieldrin and Lindane, used as insecticides and pesticides in agriculture and which damages the cytoskeleton. The thiols can be used in vivo to protect healthy or damaged cells against further damage.

Patent DE-4108000-A1 (DE)
Inventor: REINARTZ JOHANN OTTO
IPC: A01K1/015
Filed: 1991-03-13
Abstract: The advantage of the disclosed cat toilets over commercially available cat toilets is that it is automatically cleaned and supplied with fresh cat litter after use. Since the cat litter is conveyed in an air-tight closed drawer (6) provided with an exchangeable evacuation cassette (7), the annoyance caused by bad smell is largely excluded, not only obliging the human being but also complying with the cat's need for cleanliness. The problem is solved in that after each use of the cat toilets, the flexible bottom (8) is drawn away underneath the fresh cat litter kept in the supply tower (9) which scrapes and cleans the flexible bottom (8), and the used cat litter falls into the drawer (6) provided with an exchangeable evacuation cassette (7). When it moves back into its initial position, the flexible bottom (8) is supplied again with fresh cat litter by means of a dosing device (10) arranged in the supply tower (9).
