Abstract: Example apparatus for absolute position detection are disclosed. An example apparatus includes a housing and digit gears coupled to the housing to rotate about respective parallel axes. Each digit gear has a first portion including a first set of teeth disposed about an entire circumference of the first portion and a second portion including a second set of teeth disposed about only a portion of a circumference of the second portion. Each digit gear is to correspond to a respective digit in a code representing an absolute position of a shaft. A respective idler gear between each adjacent pair of the digit gears is to be intermeshed with the first set of teeth of one of the digit gears and the second set of teeth of the other one of the digit gears.

Abstract: Methods and apparatus for changing actuator output torques are disclosed. An example method includes decoupling a first end cap from a body of an actuator. A first spring assembly is positioned within a first outer chamber defined by the first end cap and the body. A first end of the first spring assembly is positioned adjacent a surface of a first piston. A second end of the first spring assembly is positioned adjacent the first end cap when the first end cap is coupled to the body. The method includes positioning a first spacer within the first outer chamber and coupling the first end cap to the body. The first spacer changes a distance between the first and second ends of the first spring assembly when the first end cap is coupled to the body to change an output torque of the actuator.

Abstract: An absolute valve position detector with self-powering capabilities is provided. An energy-harvesting position sensor is activated by the rotation of a pinion that rotates according to the opening and closing of the valve. The sensor outputs an electrical pulse that may be simultaneously used to provide power to the position detector and to indicate the rotation of the pinion and, therefore, the position of the valve. In a preferred example, the energy-harvesting sensor is activated by change in a magnetic field and the magnetic polarization of a Wiegand wire. In examples, the electrical pulse is induced in a coil wrapped around the Wiegand wire when a magnet disposed on the pinion is rotated.

Abstract: An actuator assembly includes a cylinder disposed in an actuator housing, the cylinder having a cylinder interior is in fluid communication with a source of pressurized fluid. A ram member has a piston head within the cylinder interior, and pressure on the piston head moves the ram member. An end of the ram member acts on a collar having a collar interior, and an end of a rod member is disposed within the collar interior. The rod member is displaceable relative to the collar such that the end of the rod member does not contact the collar. Accordingly, fluid in the cylinder interior acting on the ram member may expand due to thermal expansion without damaging a hard stop at an opposite end of the rod member and without losing system pressure by triggering a relief valve.

Abstract: An example rotary actuator includes a cam that is to be coupled to a valve. The cam is rotatable about an axis. The example rotary actuator also includes a linear actuator having a stem movable along a path offset from and perpendicular to the axis and a chain having a first end and a second end opposite the first end. The first end of the chain is coupled to the stem and the second end of the chain coupled to the cam. The chain is disposed around at least a portion of an outer edge of the cam, and movement of the stem along the path rotates the cam about the axis.
