Abstract: The components (11) to be examined are held by suction at a support device (10) and inspected by a video camera. The workpiece is recorded from two different sides via different beam paths (25, 26) using the same video camera, wherein two pictures of the same object are reproduced in different views and evaluated by image processing. Thus, it can be determined whether the component (11) is intact and, in particular, whether its legs (13) are present and at the correct place.

Abstract: The device for separating metal parts from a stream of material to be conveyed comprises a multiple-way junction (11) in the form of a rotary tubular multiple-way junction. The rotary tubular multiple-way junction contains a rotary element (36) configured as a stopcock having two inlet ducts (37,38) which can be selectively brought in congruence with an inlet opening (32), and an outlet duct (39). The outlet duct (39) normally leads to a material outlet (34) but is moved to the separation outlet (15) when the rotary element (36) is repositioned. A metal detector (28) responding to the presence of metal parts in the conveying duct (30) controls the rotary element (36) which is rotated by less than 90°0 for the purpose of separating the metal part.

Abstract: A device for detecting the position of a movable element of an adjusting member operated by fluid pressure. A cylindrical probe is introduced into the wall of the actuator and extends to near the inner surface of wall. The probe is mounted to be axially displaceable at the holder so that it may be adapted to different wall thicknesses. The holder contains a sealing means for sealing the passage of the cylindrical probe, which is extended by the shaft and is adapted to be rotatable in a thread bore at the rear end of the holder. A circuit box accommodating the electric circuitry is secured to the end of shaft. The position detector, which detects when the piston has approached the probe, may be simply adapted to different cylinder wall thicknesses. This eliminates the requirement of using different types of position detectors whose probes vary by the length of their projection.

Abstract: A device for sorting out metal particles from a current of conveyed material, such as grinding stock or granular material, including a retarding device in the form of a whirling chamber between a metal detector and a sorting device.
