Abstract: Non-yellowing finishing agent comprising an optionally sulphonation-solubilized aldehyde condensation product with a hydroxyl-containing aromatic body and a stabilizing reductant.

Abstract: The invention relates to a process for protecting reduction-sensitive dyes in the course of dyeing or printing fiber materials with dyes using a compound of the formula (I) or a mixture thereof where the substituents are each as defined in the claims; novel compounds of the formula (I) and printing and dyeing media containing compounds of the formula (I).

Abstract: A disc brake has a brake disc and a brake caliper spanning the brake disc. A brake applicator shaft is supported on the brake caliper and arranged transversely to an axis of rotation of the brake disc. The brake applicator shaft has a rotary lever for actuating the brake applicator shaft. An adjusting device provided with a thrust spindle having an end face facing away from the brake disc is provided. The brake applicator shaft transmits upon brake application a brake force through the thrust spindle onto the brake disc. A monitoring device is provided that has a measuring element moveable relative to the brake caliper and resting against the end face of the thrust spindle.

Abstract: In order to determine the complex pulse response of a radio channel, for instance in a digital mobile radio network, signal portions of the wanted signal transmitted via the radio channel, which signal portions are preset at the receiver end, are measured and the pulse response is then calculated from the signal portions by linear transformation.
