摘要： The rotary expander device combines a square working chamber with a three lobed sext-arcuate rotary working member which defines four expansible and contractible spandrel chambers in the corners of the square as the three lobed rotor revolves and its external surfaces make wiping contact with the interior surfaces of the square working chamber. Fluid flow from exterior intake and exhaust ports to four ports in the spandrel corners is controlled by a rotary valve coupled to the drive shaft, which is coupled to the center of the rotor. The ports and valving provide sequential spandrel chamber expansion and contraction with intake and exhaust of fluid as the sext-arcuate rotor revolves with its center describing a retrograde circular orbit around the center of the square chamber. The device may serve as either a motor when fluid driven or a pump when shaft driven.

摘要： Apparatus (10) for generating a radar waveform (W). A noise generator (20) generates a series of pulses in a pseudo-random pattern, and a frequency generator (16) generates a carrier wave having a frequency within a predetermined band of frequencies. The carrier wave is modulated with the pseudo-random pattern of pulses, and the resulting modulated carrier wave passed through both a filter (30) and an attenuator (32) to suppress any discernible feature or signal characteristics of the resulting waveform. The modulated carrier is transmitted by an antenna (42) and a received return signal is processed by a signal processor (100) to obtain pertinent information about a target. The transmitted waveform has no discernible attributes by which the waveform, if processed and analyzed by someone else's radar detector (E) would convey any intelligence as to the presence or source of the transmitted waveform.

摘要： An axial piston machine having double acting piston assemblies incorporating swivel joints from which connecting rods extend to drive points on the radial arms of a wobble plate, the central pivot of which is established by a universal joint support. The wobble plate is connected by a crankpin and a crankarm to a crankshaft establishing a precessing driving plane at a tilt angle to the crankshaft axis of preferably less than 18.degree.. A valve rotatable about the crankshaft axis controls the supply and exhaust of fluid to the piston assemblies.
