Abstract: An adjusting drive operated by a pressure medium with a spring-loaded roller diaphragm secured to plates and displaceable within a housing by the pressure medium; the roller diaphragm actuates an adjusting member that is securely connected with a plate and extends out of the housing; in addition to its end positions, the adjusting member is also able to assume at least one intermediate position; the plates are thereby connected with each other by the roller diaphragm while a plate not directly connected with the adjusting member sealingly rests on a ring-shaped abutment projecting out of the inner wall of the housing in the intermediate position of the adjusting member.

Abstract: The passenger compartment of a motor vehicle operated at least partially on hydrogen may be heated after the engine is shut off by using a LT/HT hydride combination reservoir as the hydride reservoir for the vehicle. The heat capacity of the reservoir, present after the engine is shut off or produced by charging the HT reservoir with hydrogen from the LT reservoir, is supplied at least partially to the passenger compartment.

Abstract: An installation for changing the position of the upper fastening or deflection point, especially of the deflection fitting of a three-point safety belt with automatic belt roll-up mechanism in a two-door passenger motor vehicle without center column, in which the deflection fitting is provided at the upper end of a bearer adapted to be transferred from a lower rest position covered off by the inner vehicle side wall covering, into an upper use position projecting beyond the side wall covering.

Abstract: 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.

Abstract: A public passenger local traffic system with vehicles capable of driving either on streets or guided mechanically transversely in drive channels with at least approximately vertically extending switch guide surfaces being provided within an area of drive channel bifurcations or mergers, which are arranged substantially parallel to the respective outer continuous channel side and point away from the drive channel. The switch guide surfaces serve to guide the vehicles on both sides by means of switch guide rollers which are mounted laterally at the vehicle and having a substantially vertical axis. The switch guide rollers each have an at least approximately vertical roll-off surface in the operating position which cooperates with the switch guide surfaces. The switch guide rollers are supported on switch guide levers whose pivot axes are arranged at least approximately at the same height as the center of the switch guide surface.

Abstract: A method for producing two-component varnishes or paints involves withdrawing at least one colored basic varnish from a preselected source and introducing the varnish into a mixing zone, withdrawing a colorless hardener or cross-linking agent from another preselected source and introducing the hardener or cross-linking agent into said mixing zone, and maintaining a prescribed and previously adjusted mixing ratio between the varnish and the hardener or cross-linking agent by controlling the rate of flow of at least one component of the two-components, the basic varnish or the hardener or cross-linking agent, by a controllable metering means. The mixing ratio between the two components being determined by a means measuring a selected parameter of the mixture produced in the mixing zone. A suitable and measurable parameter of the mixture may be the electrical conductivity of the mixture, the dielectric constant of the mixture or the like.
