Abstract: A fluid-actuated rotary actuator includes a housing having a tubular body extending in an axial direction, in which is provided a drive piston assembly for driving a rotatably mounted output shaft, which extends perpendicular to the axial direction through the tubular body and the axial end of which is routed out of the tubular body at an upper wall section of the tubular body, further including a magnet assembly associated with the axial end of the output shaft and receiving a rotary movement of the output shaft, and further including a position feedback device configured to detect the magnetic field generated by the magnet assembly and to provide, in accordance with the detected magnetic field, a position signal corresponding to a position of the output shaft, wherein the position feedback device is located in a receptacle chamber formed in the upper wall section of the tubular body.

Abstract: A position indicator for a rotary drive of a process valve is proposed, which can be mounted on a rotatable indicator shaft of the rotary drive and which has a base indicator element and an additional indicator element, wherein the additional indicator element can be positioned and fixed about a vertical axis in different angular positions. On the base indicator element a plurality of base indicator markings are arranged, while the additional indicator element has an additional indicator markings. In order to indicator various visually perceptible valve-type symbols, the additional indicator element can be positioned, inter alia, in at least one cover angle position, in which it covers at least one base indicator marking, but leaves at least one further base indicator marking uncovered, which together with the always visible additional indicator marking represents the valve-type symbol.

Abstract: The device for adjusting a time indicator includes a gear train (1), the kinematic chain of which includes a sliding pinion (2) driven by a driving wheel set (3). The sliding pinion drives a driven wheel set (4) when the driving wheel set rotates in a first direction (A) and disconnects from said driven wheel set when said driving wheel set (3) rotates in a second direction (B), opposite to the first direction. The shaft (6) that the sliding pinion (2) includes is engaged in a groove (7) having first (9) and second (12) end portions, at least the first end portion (9) of which is directed radially (R) to the driven wheel set (4).

Abstract: The mechanism (9) for triggering a striking work, is disposed between a timer (11), which is used to countdown and to display a pre-determined time interval on a dial, and a strike train (14) in order to make said striking work heard when the timer has counted down completely. The mechanism essentially comprises a lever (1) which is fitted with a leaf spring (3) and a locking stone (2).

Abstract: In order particularly to put a watch into beat and adjust the isochronism, in addition to the poising screws (2a, 2b) of the balance (1) and the fine adjusting screw (7) pressing on the index tail 20a to alter the orientation of the index (20), the device includes, on the one hand, two screws (19, 29) respectively fixed in the balance cock (10) and in the index (20) to maneuver clamps by means of L-shaped rocking elements (13, 23) to fix the end of the balance spring and define its useful length, and on the other hand, a screw (9) for immobilizing the index (20) in a determined position, these three screws (9, 19, 29) enabling a fine adjustment to be carried out.
