Abstract: An actuation device for a motor vehicle, in particular for specifying a braking and/or acceleration request, with a first and a second housing portion is disclosed. The first housing portion includes an actuating surface on a top surface facing away from the second housing portion, or a cover with the actuating surface is arranged on the top surface. The housing portions are connected to each other by a hinge. An axis of rotation of the hinge is arranged laterally spaced apart from the actuating surface.

Abstract: Novel carboxylic acid dianhydrides are obtained by esterifying or trans-esterifying hydantoindiols, or diesters thereof, of the formula ##STR1## in which m and n are each a number from 1 to 4 and R.sub.1 and R.sub.2 are each an alkyl having 1 to 5 C atoms, or R.sub.1 and R.sub.2 together are the pentamethylene radical, R.sub.3 is a hydrogen atom or methyl and R.sub.4 is a hydrogen atom, acetyl or propionyl, with trimellitic anhydride.The novel dianhydrides are valuable curing agents for epoxide resins and are suitable for the preparation of polymers which are derived from carboxylic acid dianhydrides.

Abstract: The invention relates to a trimellitic anhydride ester mixture which is suitable for lacquers and which is obtained by heating trimellitic anhydride together with a diol, in the molar ratio of 1:1 to 2:1, for at least 4 hours at 190.degree. to 250.degree. C., at an external pressure of 5 or 30 Torr for at least part of this time, and in the absence of a catalyst.The mixture is used as curing agent for the epoxide resin in a laquer containing epoxide resin and optionally pigments. The lacquer is used for the inside coating of tins (cans) for foodstuffs.
