A pane made of glass or plastic, whose optical degree of reflection can be controlled by switching between two different interference conditions. As a result, the transmissibility with respect to sun radiation can be reduced very efficiently and an excessive heating of glazed objects can be prevented. Preferred applications of the invention are the climate control of motor vehicles, rail vehicles, airplanes and buildings.

Reflectively controllable glazing

In an arrangement for marking of vehicles to hinder theft or unauthorized sale, the marking permanently applied to the vehicle comprises a multiplicity of microscopic information carriers having data (secondary information) encoded thereon which data normally coincides with information providing details on the identity of the vehicle (primary information) stored in some other way and not accessible to manipulation. Many thousands of information carriers encoded with the secondary information are incorporated in the manner of pigments into a vehicle coating, at least at certain locations.

A process for heating the passenger compartment (10) in a motor vehicle, particularly an electric vehicle, having a heating device (12), which is supplied with an air current (40) extracted, via a waste-air duct (11), from the passenger compartment (10). The air current enters into the passenger compartment (10) from the heating device (12) via an intake-duct (13). In order to prevent internal misting of the vehicle's windows, even with a low heating capacity, at least one partial air current (40a), which is branched off from the air current (40) prior to entry into the passenger compartment (10), flows through a sorbent (15) such as zeolite or the like.

The invention relates to a sorption method for air-conditioning vehicles, especially electric vehicles, and a device for working the method. To achieve rapid cooling or heating by means of vehicle air conditioning while achieving improved manufacturing, cost, and weight advantages, it is proposed that the sorption unit, composed of a storage container with sorbent, a supply container with sorbate, and a steam duct connecting the containers with one another, is evacuated only to perform an adsorption process employing a vacuum pump and is vented for desorption. The sorbent located in the storage container is traversed by hot air for desorption, said air, moistened with sorbate after passing through, being vented to the environment past the supply container after flowing through a vent line that branches off the steam duct.

The invention relates to a motor vehicle with an air-conditioning system which contains an environmentally compatible, non-flammable and non-toxic circulating medium. In order to avoid any risk to the vehicle occupants in a vehicle crash as a result of fire breaking out, it is proposed that the circulating medium be used as an extinguishing medium in the event of a fire breaking out on the motor vehicle.

A wind-up mechanism for eliminating the belt looseness of a safety belt system when exceeding a predetermined deceleration, in which an ignitable propellant charge, provided for triggering the retraction movement of the belt is arranged centrally in the hollow shaft of a belt roller that blocks automatically in case of danger. A liquid medium is preferably disposed in front of the propellant charge which, after the ignition of the propellant charge, drives a rotor coupled at that instant with the wind-up roller so as to eliminate the belt looseness by the gases forming during the ignition of the propellant charge. The hollow shaft accommodates at one end a cap and a toothed rim connected therewith, into which engages a blocking mechanism triggered in case of danger, while at least a part of the rotor is formed-on at the other end of the shaft in the course of a cold-flow or casting operation.
