摘要： An hydraulic pump or motor, accepting fluid at an inlet passage and translating the fluid to higher pressure at an outlet passage is constructed with a by-pass line communicating the inlet and outlet. A valve member, responsive to an abnormal condition, normally closes the by-pass line; but in the event an abnormal condition is sensed, such as abnormally high temperature or pressure, the valve is set to a position where the by-pass line is opened, whereupon the working members of the device merely circulate fluid between the passages.

摘要： The corners of the lip of a power shovel adjacent the digging edge of the lip are protected by removable guards, more specifically in the form of teeth, and projecting forwardly at each corner; each corner guard preferably includes an integral shroud embracing the portion of the digging edge of the lip which intervenes between the corner and the next adjacent dipper tooth, the latter being of any preferred form. Additionally the guard is so constructed as to present an extension at the rear thereof constituting a portion of the side wall of the dipper.

摘要： Fixed displacement hydraulic transducer apparatus of axial piston type having a rotatable piston barrel mounted within a body, a rocker cam defining a swash plate mounted in pivotable relation within a cam cradle defined within the body, and a plurality of pistons axially mounted within the piston barrel and abutting the swash plate. The pistons are adapted to reciprocation upon rotation of the barrel relative to the swash plate. The rocker cam may be pivoted to any angle relative to the axis of the pump from a maximum angle in one direction through a zero deviation to a maximum angle in the other direction to provide a constant rate of fluid displacement through the apparatus which is adjustable to a maximum rate from a minimum rate to a maximum rate in either direction. Anchor means are provided in association with the rocker cam and the body to fix the rocker cam at any position within its range of adjustment in a manner permitting the apparatus to be operated at a corresponding rate of fluid displacement.

摘要： A precision constant-speed control for a motor or other prime mover driving an output shaft and equipped with a speed control device, such as a servo valve, reponsive to an applied D.C. control signal. The precision control includes a prime signal generator developing a prime electrical signal having a frequency that varies with changes in the shaft speed; the prime signal is applied to a solid-state synchronous gating detector, having a filter connected to its output, to develop a D.C. control signal which varies in amplitude as a linear function of the frequency of the prime signal. This control signal is applied to the speed control device to maintain the prime mover speed constant within about one percent.

摘要： A railroad car retarder, adapted for installation in a classification yard or the like, and of the weight-compensating type, is so constructed as to reduce substantially the hydraulic requirements used for positioning the retarder. This is accomplished by operating four rock shafts simultaneously from a single source of power.

摘要： An automated control system for the track switches on the hump tracks of a two-section classification yard having two inlet hump tracks interconnected by a cross-over, allowing manually controlled or automated routing of cars from each hump track to any destination track in either section of the yard. The control system, actuated primarily by two selector switches, affords three distinct operating conditions: (1) automated route switching from the first hump track to any classification track in either section of the yard; (2) automated route switching from the second hump track to any classification track in either section of the yard; and (3) cross-over switching from either hump track to the other under manual control. The system automatically inhibits other operating conditions to preclude erroneous operation.

摘要： In a reversible fluid power transfer package, sensing means detect which of two mechanically interconnected fluid pressure translating devices is required to operate as a pump and which is required to operate as the motor. In response to a signal from the sensing means, dual-functioning check valve-flow limiter components associated with each device are ported according to the required mode of function of the respective device, so that whichever device is to operate as the motor is automatically provided with a flow limiter valve, and whichever device is to operate as the pump is automatically coupled to a check valve on its outlet side. The check valve may incorporate variable bypass features.
