摘要:
A mixture of the compound of the formula II--CH.sub.2 CONH.sub.2 (I)with amines or quaternary ammonium compounds is used to control, in particular, micro-organisms in water and in aqueous systems.According to the invention, the compound of the formula I can also be employed without additional biocides for the control of micro-organisms in certain selected systems. These include, for example, swimming pools, ponds, cooling water, cutting and drilling oils, cellulose compositions, glues and starch pastes.Agents which contain the biocide mixture or the compound of the formula I, together with auxiliaries, are claimed.
摘要:
The invention relates to the use of diamines of the formula I ##STR1## in which R and R.sup.1 are, for example, identical and are alkyl, as active substances for the control of harmful organisms in water and other materials, especially industrial materials. Inter alia, bacteria, fungi, yeasts and algae are controlled.The control is effected in standing and running waters. In preservatives and disinfectants, the diamines are used for natural and synthetic materials, especially industrial materials.

A method of using mono- or dibromodicyanomethane for controlling harmful organisms in water, in aqueous systems, in oil or in fuels is disclosed. The compounds act extremely rapidly in very low concentrations.
摘要:
A non-contacting sealing arrangement for sealing two counter-rotating shafts with the aid of a housing having a tire-casing-like shape which surrounds at least one centrifugal disk connected for rotation in unison with one rotatable shaft and laterally surrounded by the casing-like part with a narrow gap; the casing-like part is arranged eccentrically to the axis of the shaft on which the centrifugal disk is mounted in order to thus assure a return feed for the liquid sealing medium, such as oil, to bearing places. The invention enables alternate pressure loads and is particularly suited in applications between at least two bearing chambers of aircraft propulsion units.
