  • Patent number: 11002347
    Abstract: An actuator system can be used to adjust a position of a component in a spatial light modulator. The actuator system has a pair of actuators that are coupled together by a frame that is used to adjust the height of the component relative to the substrate. The frame includes a pair of moment arms that are coupled to the actuators and a pair of connecting arms that are coupled to the moment arms. The connecting arms are then connected together at about the center of the frame, which portion of the frame can be used to raise or lower the plate. The center of the frame can be raised or lowered by a shortening or lengthening of the connecting arms relative to each other.

  • Patent number: 10995856
    Abstract: In a parking lock for an automatic transmission, an electrical parking lock actuator has an electric motor, a spur gear stage driveable by the electric motor, and a worm gear stage driveable by the spur gear stage. A worm shaft of the worm gear stage is connected rotationally conjointly to an output gear of the spur gear stage, and a worm gear of the worm gear stage is connected rotationally conjointly to a transmission-side parking lock shaft. The worm shaft is fixed in an axially displaceable manner in the output gear. A stop limits the pivoting movement of the worm gear when a parking lock position of the parking lock shaft is reached. A spring braces the worm shaft in an axial direction of the worm shaft against a holding mechanism which is situated in a stop position, in which the holding mechanism is fixed by an electrically energized electromagnet.

  • Patent number: 10947825
    Abstract: Cushioning dampers are beneficial for preventing stress cracks on a sucker rod reciprocating pump whose circular arc head is contiguous with a counterweight and is pivotably connected to the pitman arm, crank arm weight, and speed reducer. The pitman arm is substantially horizontal and the crank arm to wrist pin phase angle is about 70-90 degrees. Auxiliary counter weight extends from the head weight on a stinger and the head weights are adjustable. The head weight diameter is either constrained within the circular arc head's outer diameter or can be larger. The upper pitman bearings are outboard on the equalizer which is integral with the head. The center bearing of the head is outboard on the rectangular sampson post. The head counterweight increases permissible load on a speed reducer. This invention has embodiments for adjusting sampson post height and pitman arm length; and for changing the stroke length without removing the wrist pin from the crank weight hole.
