Patent DE-2544577-A1 (DE)
Inventor: DEMUS DIETRICH DIPL CHEM DR
IPC: C07C255/53
Filed: 1975-10-04
Abstract: New compounds of the general formula (I) <IMAGE> where R and m are each as defined in Claim 1, are used as crystalline-liquid nematic substances for electro-optical arrangements. The compounds can be used alone or mixed. Suitable mixture components include not only the substances of the formula (I) but also other crystalline-liquid substances and optically active non-crystalline-liquid substances. Owing to their high stability to air, light, heat, water and chemical effects and also on account of the large positive dielectric-constant anisotropy, the compounds of the formula (I) are particularly useful for electro-optical cells with a homogeneous or twisted structure of the liquid crystal.

Title: Microbiological sulphuric acid prodn. - from sulphur and pyrites mixt., used for leaching ores, clarifying water and bleaching earth prepn.
Inventor: SCHWEISFURTH REINHARDT PROF DR
IPC: C12P3/00
Filed: 1975-12-18
Abstract: Microbiological H2SO4 prodn. is effected by using a mixt. of S and pyrites as raw material. The H2SO4 prepd. is used for leaching oxidic ores, e.g. U ores, clarifying waste waters and the prepn. of fuller's earths from less active clays. The H2SO4 obtd. has a high degree of acidity. Acidity achieved by microbiological S + pyrites oxidn. is higher with pyrites alone. Fe oxide presence, caused by use of pyrites, is advantageous in technical processes, e.g. catalysis of U ore oxidn.; flocculation in clarifying waste waters; detoxication of bacterial poisons, e.g. As, by partial hydrolysis by means of Fe2(SO4)3 formed. A mixed bacterial flora obtd., contg. Thiobacillus types in addn. to Thiobacillus ferrooxydans and an accompanying flora, can be controlled more easily.

Patent DE-2642288-A1 (DE)
Inventor: WALZ ALFRED PROF DR ING
IPC: H01F38/10
Filed: 1976-09-21
Abstract: This transformer exhibits a series resonant capacitor (8) in the secondary load circuit and an iron core (1) of grain-oriented magnetic sheet-metal material with DC-isolated primary (2) and secondary (3) winding and with leakage yokes (4). The active iron and copper winding parts are installed in a can (7) consisting of metal material and predominantly used for removing dissipated heat, fully electrically insulated but resting closely against the can. The completely assembled transformer is impregnated and cast, using an epoxy casting resin. In order to increase the power density when operating gas discharge tubes or gas discharge lamps with the aid of the constant current transformer but keeping the losses low, it is provided in this constant current transformer that in the main magnetic circuit which exhibits a mean iron path length lm, a continuous non-magnetic gap (5) is arranged which has such a total length  delta  that  delta /lm is greater than 0.002, which results in a maximum magnetic induction Bmax of at least 1.7 Tesla at the primary winding (2) of the transformer at nominal mains voltage. It is also provided that the non-magnetic interlayers are fixed in the said gaps (5) by the impregnation with epoxy casting resin and that the surface of the can (7) is at least 40 % greater than the surface of the transformer parts. It is well adapted for lighting systems because of its high power density and therefore small installed dimensions. <IMAGE>
