摘要： A pressure regulated constant flow valve has a fixed orifice and a regulated orifice in series, the regulated orifice maintaining a constant pressure drop across the fixed orifice. To maintain the pressure regulation effective for either direction of flow through the valve, a shuttle valve shifts when the direction of flow is reversed and reverses the connections of the regulator with the upstream and downstream sides of the fixed orifice.

摘要： An endless-chain transport system for a photocopy machine is described for gripping copy sheets at a paper-feed station, transporting the copy sheets past a photoconductive drum while holding surfaces of the copy sheets in close proximity to the drum, and transporting the copy sheets to a copy-sheet-delivery station. The transport system comprises gripper bars mounted on transport chains having gripper jaws which are opened and closed by cams to grip and release the copy sheets. Gripper-bar bumper pads are mounted on the gripper bars to hold the gripper bars away from the photoconductive drum.

摘要： A doppler speed log for marine vessels transmits fore and aft pulses of high frequency sonic energy. The log normally operates in a mode such that a gating pulse permits signal processing circuits to respond only to signals derived from reflections from minute scatterers in the water occurring at a specified distance from the hull of the vessel. If the vessel is in shallow water, a variable threshold comparator permits the signal processing circuits to respond to reflections from the sea bottom when the magnitude of these reflected signals exceeds the threshold level. The processing circuit forms fore and aft enabling pulses each having a duration equal to the time required for the reception of a specified number of cycles of sonic energy reflected from the fore and aft directions, respectively. Pulses from a calibrated clock source are applied to an up-down counter during the time that only one of the enabling pulses exists. The readings corresponding to a specified number of transmitted pulses are accumulated and displayed on a suitable readout means.

摘要： A rotary sliding vane pump or motor has pressure loaded cheek plates on each side of the revolving rotor and vanes. The cam ring has alternate major and minor diameter circular arcs connected by rising and falling ramps along which fluid displacement occurs. End covers and cheek plates of similar configuration enclose the end faces of the cam ring, rotor and vanes. The cheek plates have pressure loading cavities of circular form opposite each ramp. All of the cavities on each end are connected with a terminal in the adjacent end cover and alternate cavities are perforated to provide fluid passages into the working chambers of the device. The intermediate cavities on each cheek plate are blind. The cheek plates are so located that a perforated cavity on one end lies opposite a blind cavity on the other end of the device and the areas of the cavities are chosen to slightly overbalance the pressure forces existing at the interface between the rotor and cheek plates.

摘要： Apparatus for providing a measure of the true angle of attack of an aircraft without external probes or vanes, which measure is derived from computations involving measurements of longitudinal and normal accelerations of the aircraft in conjunction with air data derived computations of vertical speed and true airspeed. Supplementary outputs of the angle of attack computer are instantaneous vertical speed of the aircraft which is accurate under pitch and roll maneuvers, true flight path angle, and acceleration of the craft along the flight path.

摘要： The radio navigation system provides simple instrumentation for transmitting omnidirectional radio waves from a reference location and for determining the azimuth and elevation angles of arrival of the transmitted waves at a remote receiver. An array of paired receiver antennas is employed for the measurement of differences in time of arrival of the transmitted waves at the paired antennas and these values are manipulated by a simple analog computer to yield the desired azimuth and elevation data.
