摘要:
A collapsible hard top for a convertible including a top panel, two side longitudinal top carriers, two rear posts adjoining the two side top carriers from behind, respectively, a top element including a rear window of the convertible and displaceable relative to the top panel, and support and guide rails forming a displacement guide for displacing the top element, together with the rear top posts, with the support and guide rails being arranged in drop-down position relative to a rear panel of the convertible and within a trunk, and with the top panel being formed of at least two longitudinal sections at least one of which is supported for displacement in a longitudinal direction of the convertible on the two side carriers.
摘要:
A device and method for data transmission between a transducer and a processing unit which are coupled by one or several signal transmission lines, to selectively activate at least two different modes of operation of the transducer. The device includes a comparator unit which identifies the respectively activated mode of operation by comparing signals present on at least one signal transmission line with predetermined reference signals.
摘要:
A process for photochemical stabilization of non-dyed and dyed polyamide fibre material and mixtures thereof with other fibres which comprises treating the fibre material with a fibre-reactive copper complex of bisazomethines prepared from, for example, salicylaldehydes and aliphatic diamines is described. Some of these copper complexes used are novel compounds. The polyamide fibre material, for example textile material, thus treated largely retains its extensibility and elasticity even after relatively prolonged exposure to light. In addition, a clear improvement in light-fastness is achieved in dyed material by treatment with the metal complex.
摘要:
New fluorinated carboxylic acid amides of the formula ##STR1## are provided wherein R.sub.f is a perfluoroalkyl radical with 1 to 18 carbon atoms, R is hydrogen or methyl, R.sub.1 is hydrogen or R.sub.f CHOHCHR--, if m is 1, and hydrogen, alkyl with 1 to 18 carbon atoms, cycloalkyl with 5 or 6 carbon atoms, hydroxyalkyl with 2 to 6 carbon atoms, alkoxyalkyl with 1 to 4 carbon atoms in the alkoxy moiety or R.sub.f CHOHCHR--, if m is 0, A is an ethylenically unsaturated hydrocarbon radical with 2 or 3 carbon atoms, m is 0 or 1, y is 1 or 2 and p is an integer from 2 to 6. The fluorinated carboxylic acid amides are useful e.g. as wetting agents, emulsifiers or dispersants and for producing oil-repellent finishes on porous or nonporous substrates or as intermediates for the manufacture of homo- or copolymers, which show also oil-repellent properties.
摘要:
New perfluorinated amino compounds of the formula ##EQU1## ARE PROVIDED WHEREIN R.sub.f represents a perfluorinated hydrocarbon radical with 1 to 18 carbon atoms and R represents hydrogen or methyl each of R.sub.1, R.sub.2 and R.sub.3 independently represents hydrogen or the radical ##EQU2## in which R.sub.f and R have the meanings already assigned to them, p is an integer from 2 to 6 and m is an integer from 1 to about 500.Due to their surface-active properties the new compounds are useful e.g as foaming, wetting and levelling agents or as emulsifiers. They can be further used as soil-repellent additives for polishes and waxes, as corrosion inhibitors in oils or lubricants and they are also useful as intermediates for the manufacture of oil and water repellents.
