Abstract: A rotary hydraulic machine which includes a housing having a shaft mounted for rotation within the housing about a shaft axis. A cylidner block is coupled to the shaft for co-rotation with the shaft within the housing and includes a plurality of cylinders disposed in a circumferential array parallel to and surrounding the shaft axis. A piston is disposed to reciprocate within each of the cylinders and is coupled to a yoke for determining displacement of the pistons within the cylinders. A valve plate is mounted on a valve block and includes kidney-shaped slots for registering with the cylinders as the cylinder block rotates, and thereby connecting the cylinders to pump input and output ports. A microprocessor-based controller is externally mounted on the pump valve block and includes internal memory having various remotely-selectable control programs prestored therein.

Abstract: A method and apparatus for use in measuring the physical profile of a road surface and a methodology for frequency domain representation of the profile is disclosed. Force transducers and accelerometers are incorporated at each of the four wheels of a vehicle to measure the perturbations of the road surface in a direction normal to the surface over which the vehicle is driven. The disclosed implementation isolates the measurements from the motion of the vehicle body. A shaft encoder is incorporated at each of the front wheels to measure rotation of the wheels allowing the determination of distance traveled. A methodology for analysis of the data is also disclosed which provides vertical displacement data of the wheel/terrain interface while reducing the introduction of errors as the information is processed. Further methodology is used to analyze the data in the frequency domain and provide for the quantification of road/terrain characteristics useful for accelerated life testing of vehicles.

Abstract: The invention concerns novel renin-inhibitory peptides which are useful for treating renin-associated hypertension, congestive heart failure, hyperaldosteronism and diseases caused by retroviruses including HTLV-I and -III. Processes for preparing the peptides, novel intermediates useful in the preparation thereof, compositions containing them, and methods of using them are included. Also included is a diagnostic method which uses the compounds to determine the presence of renin-associated hypertension, congestive heart failure, or hyperaldosteronism.

Abstract: A bearing comprising a body of polymeric material and a reinforcing member embedded in the body and having a plurality of perforations throughout which are affixed in the reinforcing member. The polymeric material extends through the perforations. The bearing may have various configurations. The reinforcing member may comprise a thin metal sheet having perforations therein, a woven metal body defining the perforations, or adjacent woven metal bodies each having perforations. In one form, a backing member is adhered to on one side of said reinforcing member. Where a thin metal sheet is used, it has a roughened surface finish at the interface with the plastic body.

Abstract: A single cast solid propellant rocket motor grain having a centrally positioned rod portion integrally connected to an outer cylindrical portion at a base portion and comprised of a unitary solid propellant rocket motor grain wherein the central rod portion is approximately twice the thickness of an outer cylindrical portion and having the geometric dimensions and shape to achieve substantially a simultaneous burnout of the propellant burning surfaces after maintaining a burning neutrality from ignition to completion of propellant burning.

Abstract: An air heating system for a compression ignition engine comprises a combustion chamber which includes a burner through which fuel is supplied to the combustion chamber. A two stage fuel pump is provided to supply fuel to the burner with the output of the second stage being connected to the burner and the input of the second stage being connected to the output of the first stage. Valve means is provided to ensure that there is substantially no pressure drop across the second stage of the pump and control means is provided to control the speed of operation of the pump so that the rate of fuel delivery to the combustion chamber can be closely controlled.
