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 sound-absorbing covering, especially a radiator covering for motor vehicles whose air channel is adapted to be traversed by a gaseous medium in a direction opposite to the direction of travel of the sound; at least one section of a channel wall of the air channel is formed by an arcuate wall portion parabolically shaped in cross section which faces with its apex the in-flow side of the gaseous medium and which terminates in an arcuate apex portion projecting into the interior space of the channel; the arcuate apex portion shields a trough-shaped recess open in the direction toward the discharge side of the gaseous medium, in which is arranged a sound-absorbing insert within the area of the focal line.

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.

Abstract: A battery with at least one cell containing an electrolyte liquid, in which the cell is adapted to be connected with the atmosphere by way of a fill-in venting connection determining its liquid level and by way of a separate fill-in connection for the filling in of electrolyte liquid and for the refilling of distilled water as well as by way of a control opening for the insertion of a testing device for checking the operating condition, and in which the free flow cross section of the fill-in connection is dimensioned so narrowly that a liquid seal closing off the fill-in connection gas-tight will form under the influence of the capillary action and of the excess pressure which will be established during the fill-in operation into the cell, when the liquid enters the opening of the fill-in venting connection which terminates in the cell; a control opening which can be restoringly enlarged in its cross section is disposed in an elastic wall and is separate from the fill-in connection and essentially closed as s
