Compsns. contain a polymer as iodine carrier, bound, free and titratable iodine and iodide, and usual adjuvants, diluents etc. (A) contain a substantially constant ratio of titratable iodine to iodide of over 2.1:1, (B) exhibit a pH value of 4-6, and (C) contain an oxidising agent.

alpha -Hydroxycarboxylic acids are continuously converted into the corresponding optically active alpha - aminocarboxylic acids. The conversion is carried out in a membrane reactor in the presence of nicotinamide-adenine dinucleotide increased in molecular weight by bonding to a water soluble high molecular weight material, a dehydrogenase specific for the alpha -hydroxycarboxylic acid, a dehydr...

The two-part hook can be fixed to a handle and is used for passing a rope around a bollard, or through a mooring ring. When the rope presses against a locking catch (5) it releases spring-loaded arms (3AB) and slides past a further spring-loaded catch (8), being locked in place, so that the arms hold the lower part of the retracting portion against the supporting one. When the rope presses against...

The material which includes paper is coated on both sides with a thermoplastic liquid-proof material. At another work station an external layer of curable printing ink in a desired design is applied, subsequently the ink is cured by a radiation treatment.

The flexible tool is for domestic use, and can be employed for gripping, bending, breaking and turning. The tool is operated by two shafted levers articulated by a rivet to two toothed sections. The lever shafts and the toothed sections are circularly bent, and enclose a variable gap. When the levers cross with the shafts, sharp and blunt teeth are exposed. The tool is esp. for the removal of caps...

The building component, partic. for a cellar wall construction, comprises at least one concrete plate, a force-absorbing frame part and a connecting piece (2) between the two. It is also possible for the component to have one or more further layers. The connecting piece comprises zig-zag bent wires, the lower bends of which are attached to the force absorption frame part, whilst the upper bends ar...

The device is for use with a forklift truck (18) in clearing snow, and comprises a plough blade (10) which, via an arm (12), is fixed to or near to the lower part of the truck frame (19). The blade is in contact with the forks (21). The forks can lift the blade from the ground, and a counterweight (24) is fitted on the forks so that the plough blade contact pressure against the ground may be incre...
