    摘要: A process for protecting nonstable or moderately stable, cohesionless to slightly cohesive geologic formations, in particular, in tunnel construction, in which drill holes are first made by boring into the formation and, following completion of the boring, the drilling rod is removed. During this removal a hardenable injection material is forced into the drill hole, whereby, using a drilling rod, a pointed rod or anchoring element is placed in position in the boring. This element remains in the boring during removal of the drilling rod, and is solidly connected to the formation by the injection material.

    摘要: A tangled fibrous material from cut glass fibre bundles, with the cut glass fiber bundler being fed into a compressed air flow and a glass fibre-laden air being deflected into a turbulent eddy flow of varying direction, so that a tangled fibrous material of wadding-like consistency is formed. Through the simultaneous addition of dry polymer-based binder powder, it is possible to obtain a tangled fibrous material as a starting product for a production of glass fibre-reinforced plastic moundings, which can be compressed to a felt. This can be packed as an intermediate or further processed in a heated belt press to glass fibre-reinforced plastic plates.

    摘要: The invention refers to antiviral and antitumor compositions which are useful for the control of viruses and tumors and which, in addition to a known antiviral or antitumor active xanthate, contain an adjuvant which increases its antiviral and antitumor action. The adjuvant is an ionic, preferably an anionic, compound with a lipophilic group and a hydrophilic group, preferably an alkali metal deoxycholate or a compound the lipophilic moiety of which is a straight or branched, saturated or unsaturated, aliphatic group with six to eighteen carbon atoms, and the hydrophilic group of which has one or two carboxyl, sulphate, sulphonate, or phosphate groups, or a pharmaceutically-acceptable salt thereof.
