  • Development of fuseal mechanical joint
    Patent number: 11603950
    Abstract: A pipe (12) coupling assembly (16, 116) includes a body (64, 120), a rib (65, 122), and teeth (56, 124). The body (64, 118) has an outer diameter and first and second inner diameter sections (68, 128, 70, 130). The first inner diameter section (68, 128) is wider than the second inner diameter section (70, 130). The rib (65, 122) extends around the first diameter section (68, 128) and projects radially inwardly therefrom. The teeth (56, 124) are situated within the second inner diameter section (70, 130) and project radially inwardly toward a central axis (38, 134) of the body (64, 120).

  • Electrical feedback device for valves
    Patent number: 9518678
    Abstract: An electrical feedback device (6) of a valve (1) is provided for feeding back the position of a hand wheel (4) of the valve (1) and thus the position of a shut-off member of the valve (1). The electrical feedback device (6) can be mounted in a spindle housing (13) of a housing upper part (2) of the valve (1). The electrical feedback device is configured so that the rotational movement of the hand wheel (4) is converted into a linear movement of a trip cam (45). The electrical feedback device (6) has a gearwheel (43) which is driven by a screw thread (42) which is mounted on a ring (41).
