Abstract: Described is an apparatus for transferring an article from a first conveyor to a second conveyor which branches therefrom. The apparatus has a drive shaft from which at least one pivot arm radially projects. A displacement member is rotatably mounted on an end portion of the at least one pivot arm. The displacement member is connected to the drive shaft by an endless loop so that, upon a rotary movement of the drive shaft the associated displacement member performs a circular movement around the drive shaft and in so doing remains in parallel orientation with respect to the direction of advance movement of the first conveyor. The pivot arm involves a lower angular speed during the phase of contact of the displacement member against an article to be transferred than during the phase of displacing the article.

Associated with each outside raised portion (14) on the inner peripheral surface (16) are a pair of inside raised portions (18) which are disposed in symmetrically laterally displaced relationship with respect to the associated outside raised portion (14).

Abstract: A collection container with transport pump (4) for conveying liquids containing production residues, for instance chips, coolant and lubricant. The collection container (1) is developed as a cylindrical pot with a substantially flat container floor (5). A rake which travels over the container floor (5) conducts the chips which have deposited on the container floor to the transport pump (4). The collection container thus has a slight structural height and assures optimal removal of the chips by means of the transport pump.

Abstract: A handgun comprises a grip (1), a slide (2), a trigger device (3) having a trigger (10) and a trigger safety lock. In order to provide a simple, ergonomically correct trigger safety lock, this safety lock is formed by a safety locking element (8) which moves vertically above the trigger device (3) in the grip (1), has, at the bottom, a hook (9) which interacts with a catch (11) on the trigger (10), in the safe position, projects visibly out of the grip (1; 60) in front of the trigger (10; 62), and has side projections (15). This safety locking element is held with respect to the grip (1) by a spring-loaded lock (18, 19, 20, 21).
