    Abstract: A hydraulic control circuit for a hydraulic motor operable at least at two displacements, having a proportional speed control valve with a control valve spool continuously moveable by means of a force generated by a pilot pressure being controlled by a continuously, electrically adjustable pilot valve having an electrical actuator, wherein the control valve spool is moveable between a full-torque end position, a reduced-torque end position, and at least one intermediate position. A time related control current function is provided for controlling the current applied to the electrical actuator for controlling the pilot pressure including a pre-current portion with a constant non-zero current and a current ramp portion during which the current is raised or lowered continuously from a ramp starting current level to an intermediate current level. The current is changed abruptly to a switching current level at the end of the current ramp portion for allowing the movement of the speed control valve spool from one of the two end positions via the at least one intermediate switching position into the other end position.

    Abstract: An air motor assembly includes an exhaust block with an exhaust port that conveys exhaust air into an exhaust manifold. The exhaust port includes an expansion chamber that creates a pressure drop in the exhaust gas, thereby decreasing the temperature of the exhaust gas. The expansion chamber is defined between a first wall that is tangential to the air motor cylinder and a second wall that is transverse to an axis of the exhaust port. Poppet valves control actuation of a shuttle. The poppet valves are disposed on the exterior of the air motor assembly and are thermally insulated from the air motor assembly.

    Abstract: A container storage facility has storage portions for storing containers, and supplies a purge gas to the interior of the containers. The container storage facility includes ejection portions that eject the purge gas, a gas supply device that controls the supply flow rate of the purge gas, a main pipe that conducts the purge gas output from the gas supply device, and branch pipes that are branched from the main pipe and are connected to the ejection portions. The ejection portions eject the purge gas regardless of whether or not containers are stored in the storage portions, and the gas supply device controls the supply flow rate of the purge gas so as to increase as the total number of containers stored in the storage portions decreases.

    Abstract: Solid particle erosion in a steam turbine is minimized by diverting through angled slots formed in appendages of outer rings of the diaphragms, a portion of the steam from the steam flow path thereby bypassing downstream rotating components. The slot through the first stage appendage lies in communication with a passage through a downstream outer ring of a following stage such that the diverted solid particle containing steam may be extracted from the steam flow path and passed to the feed water heater of the turbine. The slot in the second stage appendage diverts steam from between the first and second stages and about the second stage. Solid particle erosion in various regions, i.e., the trailing edge of the stator vanes, along the surfaces of the buckets and in the regions of the cover and its connection with the buckets as well as the sealing devices is thereby minimized.
