Abstract: A method for controlling a device for metering granular material and a metering device for metering granular material comprises a feed for the granular material from a container into a metering chamber. A metering piston can be actuated by a control device such that a gap between the feed and the metering chamber is opened by a predefined first distance and a second distance which is greater than the first distance. At least one sensor is arranged in a delivery line leading away from the metering chamber and is connected to the control device so that the metering piston can be actuated for a predefined duration such that the gap between the feed for the granular material and the metering chamber can be opened by the second distance if a blockage of the granular material is detected by the at least one sensor, so that the blockage is dispersed.

Abstract: A device and method for dispensing a friction-coefficient-optimizing mixture of at least one lubricant and at least one grit into the gap between a rail wheel of a rail vehicle and a rail. The device includes a reservoir for the lubricant, a reservoir for the grit, a metering unit for metering the lubricant, a metering unit for metering the grit, a delivery apparatus for delivering the lubricant, a delivery apparatus for delivering the grit, and a common dispensing nozzle.

Abstract: A vibration damper is proposed with two damper halves which enclose a passage opening in the assembled state and, in the installed position, bear against a component which is guided through the passage opening. The damper halves have corresponding latching means which permit an attachment of the vibration damper to the component. Each damper half has in each case one collar, which collars, in the assembled state of the vibration damper, are arranged at opposite ends of the vibration damper. The vibration damper can be mounted simply, even retrospectively. Moreover, the vibration damper can also be released again without damage.

Abstract: An exemplary holster system may include an attachment component configured to be secured on a user; a firearm holster configured to hold a firearm; and a holster adapter operatively coupling the firearm holster and the attachment component. The holster adapter may be configured for one-handed repositioning of the firearm holster relative to the attachment component along an arcuate path between a first position and a second position while the holster system is worn by the user. The first position may include a first location and a first orientation, and the second position may include a second location, different from the first location, and a second orientation, different from the first orientation.

Abstract: A device for scattering grit in front of the wheels of a vehicle comprises a housing having a feed inlet for the grit, an outlet for the grit and a substantially cylindrical recess for receiving a brush roll which is rotatably mounted and driven about a substantially horizontal axis of rotation for the metered delivery of the grit from the feed inlet to the outlet. At least one wedge is arranged in the region of the feed inlet for the grit, in front of the brush roll and tangentially and displaceably with respect to the brush roll so that the size of the feed inlet can be adjusted.

Abstract: A device for spreading granulate, particularly for spreading sand into the gap between a rail and a wheel of a rail vehicle, includes a housing, at least one inlet for the granulate and at least one outlet for the granulate, an axially movable metering piston and a compressed air connection, which leads into a pressure chamber and serves for actuating the metering piston by compressed air to meter the granulate.

Abstract: A method controls an UPS with a system having: first and second terminals, a switch having: first and second switch terminals respectively connected to the first and second terminals; first and second thyristors connected between the first and second switch terminals in anti-parallel; and an inverter connected to the second terminal and the energy store. Switch current and a first potential at the first terminal are detected. In a first fault, where the first potential drops past a first rule and the switch current rises above a second rule: a second potential at the second switch terminal is set using the inverter so the switch current becomes zero. Then the switch current is compared with a second threshold, and if it is exceeded, a first check result is positive, otherwise it's negative. When positive, the second potential is reversed.
