Patent DE-1810688-A1 (DE)
Title: Dynamic filter press
Inventor: LAMBALLERIE GUY DE
IPC: G01N15/08
Filed: 1968-11-25
Abstract: Filter press described in the main patent makes it possible to study the filtration of all types of mud, across a sample of earth placed in the axis of the apparatus. The displacement of the fluid being effected by an immersed stirrer. The present patent improves this by provision of a stirrer, which is constituted by a squart cone arranged with the point downwards in contact with the bottom of the vat or vessel. The Hassle cell containing the sample to be studied is placed in an off-centre opening of the vessel. Preferably this vessel is cylindrical, and its upper part is internally grooved so as to receive directly the screw cap through interpolation of a simple toroidal sealing joint.

Patent DE-1911587-A1 (DE)
Title: Process for urea feed for ruminants
Inventor: HORSTMAR HECHT DIPL-CHEM DR
IPC: A23K50/15
Filed: 1969-03-07
Abstract: A process for urea feed for ruminants consists of the use of a granulated urea having a physiological neutral coating and which results in a lowering of the solubility rate of the urea in the acid medium of the stomach of the ruminant. The decreased solubility of the urea permits a much better utilisation and a higher conversion to albuminous food material by microbioligal action in the stomach. In this way it is possible to use urea as a cheap and effective high nitrogen contng. material. More specif. the urea is coated with an aqueous dispersion of a film-forming copolymerisate from at least two of, vinylchloride, vinylidene chloride and methacrylic acid ester. The ratio of urea:coating is 6.5-1.5:1.

Patent DE-1941767-A1 (DE)
Title: Water supply to a cooling system
Inventor: GLAUDE KRUG JEAN
IPC: C21C5/40
Filed: 1969-08-16
Abstract: Water is syphoned from a constant-level supply container to the cooling enclosure, and from there to a collecting container. The syphon action is primed by a pump, after which it proceeds automatically. In the event of rupture of the inner wall of the cooling enclosure the syphon action is broken and much of the water already in the enclosure driven back to the supply container. The system is designed particularly for cases where the cooling enclosure is exposed to very high temps., where the effects of water leakage through a rupture can be dangerous. Particular applications are to steel making (oxygen lance refining), to collector hoods for gases from converters, and to continuous-flow ingot moulding.
Patent DE-1945511-A1 (DE)
Title: Controlled release formulation of - differing medicaments
Inventor: HESSE GUENTER DR MED
IPC: A61K9/24
Filed: 1969-09-09
Abstract: In a time-controlled pharmaceutical combination with polytopic sites of action, multidimensional medication is rendered possible by combining different pharmaceuticals having antagonistic, contrary, or otherwise differing efficiency, the resorption gradients of the individual ingredients being adjusted to the required extent so that e.g. hypnotics, stimulants, laxatives circulatory agents etc. can be administered simultaneously. This gives a valuable simplification of dosage regimens when, for example, administering psychopharmaceuticals together with other medicaments required to counteract such undesirable side-effects as hangover, constipation and hypotension.

Title: Electrolytic metal extraction process
IPC: C25C7/06
Filed: 1971-02-03
Abstract: Hydrometallurgical process includes refining in an electrolytic cell in which particles of the unrefined metal or metal sulphides are suspended in the area round the anode and nuclei of the pure metal are suspended round the cathode. The particles collide with the anode or cathode respectively whilst an electric current is passed through the cell contg. the electrolyte. On collision with the electrodes the particles-receive positive or negative charges resulting in corresponding electrochemical reactions taking place with the electrolyte. Preferred the cell is oscillated both horizontally and vertically. The process cuts out several operations as compared with conventional processes. As the result of close proximity of the electrodes which is about 1.5 cm very high current densities can be used. It can be used for extraction of Cu, Zn, Fe, Co, Ni, Pb, Co.
