Abstract: An electrohydraulic power vehicle braking system for a motor vehicle driving autonomously on public roads is equipped with two redundant power brake pressure generators so that, in the event of independent driving and a failure of one power brake pressure generator, the other power brake pressure generator is able to decelerate the motor vehicle without driver intervention.

Abstract: A brake-force simulator for a motor vehicle includes a piston operatively connectible to an operable brake pedal that is guided in an axially displaceable manner in a cylinder; and at least one elastomer spring element situated in the cylinder, which acts with a spring force counter to the movement of the piston in one direction.

Abstract: The present invention relates to a package for preserving a medical device or the like comprising an external capsule and a cap sealingly engaging the external capsule, wherein a means is provided for releasingly connecting medical device with the cap upon removing the cap and the medical device from the external capsule. In a variation the package may comprise in addition a transport means surrounded by the cap and extending therein, wherein the transport means is adapted for releasingly connecting to the medical device. Also a seal may be provided at an opening of the external capsule.

Abstract: A bottle or container closure for a precise addition of a contents constituent includes a lower part having internal threads for a leak-proof application for the bottle or container, in which the lower part of the closure includes, in a clearance area, a chamber that can be closed with a membrane liner opening toward the bottom of the closure, which has a dome-shaped top side that includes a penetrating pin projecting downwardly inside the dome-shaped top side. The dome-shaped top side can be pressed downwardly, via deformation, so that the projecting pin can be pressed through the membrane liner. A pouring spout is located adjacent the chamber on the lower part of the closure, which releases through suction, or pressure, on the bottle or container.

Abstract: A device automatically applies an object (7) to a cutting edge (11) of a knife 10), and automatically makes an initial cut in the object (7), in microtomes, especially ultramicrotomes. Force sensors (27,28), length sensors (29) or other sensors, an elecrotronic control unit (25) and an encoder (22) coupled to a drive device register forces (k,-k) connected with the separation of sections by the knife edge (11) or variations in the system triggered by these forces. Subsequently, via the electronic control unit (25), a transition from a rapid speed or rate of feed to a lower cutting speed or a lesser rate of feed for making an initial cut is automatically performed. A visual and/or acoustic signal informs the user of this change. Signals (S.sub.1, S.sub.2) from the sensors (27-29) serve for automatic adjustment of the position of two switch-over points (U.sub.1, U.sub.2) from the rapid return speed (V.sub.R) to the slower cutting movement (V.sub.

Abstract: A device for controlling the drive and forward feed of a microtome, particularly an ultramicrotome, includes a driving motor for moving a specimen or knife and a servomotor for generating a forward feed of the specimen towards an edge of the knife or vice versa. A high travelling speed of the specimen needed for rapid initial cutting is coupled to a high rate of forward feed. One single switching operation is performed, for instance, by a snap-engaging step switch via relay switches. The driving motor and the servomotor can be simultaneously switched over to pairs of values which correspond to subsequent rough cutting and ultra-thin cutting. Individual values for cutting speed and forward feed are separately preselected, readjusted, and read from a display. Selected program stages are indicated by signals.
