Abstract: A power operator for switchgear for use in mains power distribution systems such as public medium high voltage distribution systems, where the switchgear comprises a closed cabinet (5) with an operating shaft protruding therefrom that is rotatable between two positions and has a coupling part. The motor operator includes a housing (11, 20, 21, 27) which is mountable on an external surface (4) of the switchgear cabinet (5), and a rotatable connection shaft connected to an electromechanical linear actuator. The connection shaft has a first coupling part which connects with the coupling part of the switchgear in a longitudinal axial sliding and non-rotational interlocking manner. The housing (11, 20, 21, 27) is a tube element which is tamper resistant, is relatively easy to seal against dust and moisture, and is inexpensive to manufacture.

Abstract: A power operator for switchgear (1) for mains power distribution systems, where the switchgear comprises a closed cabinet (5) with an operating shaft protruding there from. The operating shaft is rotable at least between two positions and has a coupling part (2, 3). The operator comprises a housing (10), which is mountable on the external surface (4) of the switchgear housing, and a rotatable connection shaft (14) connected to an electric drive mechanism (11). It has a first coupling part to fit with the coupling part of the operating shaft in a longitudinal axial sliding and non-rotational interlocking manner. The coupling part of the connection shaft (14) is a separate interchangeable part (24, 24a) of the connection shaft attached thereto by non-rotational interlocking means. Further, it has an activation knob (16) extending from the housing (10) to operate the switch manually.

Abstract: A motor operator for switchgear for use in mains power distribution systems comprising a closed cabinet (5) with an operating shaft (53) protruding there from said operating shaft being rotatable at least between two positions and has a coupling part (2). The motor operator (6, 7) comprises a housing mountable on the external surface of the switchgear cabinet. A rotatable connection shaft (51) is connected to an electric motor via a drive mechanism, and has a first coupling part (52) to fit with the coupling part (2) of the switchgear in a non-rotational interlocking manner, and further has a second coupling part (54) extending from the housing to operate the contact of the switch manually and, for which purpose, the motor operator has a release mechanism releasing the connection shaft. The motor and the drive mechanism is designed as an electro-mechanical actuator with a rear mounting (23) for mounting the actuator in the housing of the motor operator and ?.

Abstract: A linear actuator includes a reversible electric motor which drives a spindle via a reduction gear with several stages and an activation element connected with it, and an overload clutch in connection with the first stage or one of the first stages in the reduction gear. This is advantageous in terms of structure and load and greater flexibility is achieved in the construction of the structure.

The housing (11, 20, 21, 27) is a tube element which has the inherit quality that it does not invite to vandalism and unauthorized access. It is relatively easy to seal against dust and moisture. When cut from a length of a pipe it is easy to manufacture as well as inexpensive.

Abstract: A linear actuator with a reversible electric motor (2) which drives a spindle (4) via a reduction gear with several stages and an activation element (6) connected with it. An overload clutch (21) is arranged in connection with the first stage or one of the first stages in the reduction gear. This is advantageous in terms of structure and load. Greater flexibility is achieved in the construction of the structure, and the clutch is moreover not loaded so severely.

Abstract: A gripping device for nappy workpieces which is capable of handling both small and large pieces of textile materials. A gripping device is provided having a base part and a slidable part, between which is provided a substantially closed hollow to which pressurized gas is supplied through a series of slots. The slidable part is moved in such a manner that the slots are squeezed together and the gripping device grips the nap of the upper piece of textile material. Pressurized gas is led through the upper piece to the piece lying immediately below to ensure efficient separation of the upper piece from the piece below, and avoiding the inadvertant lifting of more than one piece at a time.
