Abstract: A weight measurement apparatus, includes a weight scale having a weight output for providing a weight output signal indicative of the apparent weight of an object being weighed. An accelerometer (or an array of accelerometers) is used to measure a force which contributes to the apparent weight and causes the apparent weight to deviate from the object's true weight. A computer coupled to the scale and the accelerometer computes the true weight of the object from the apparent weight and the accelerometer output. This true weight is displayed on a digital display.

Abstract: Disclosed is a counter-balanced sheave assembly for supporting a cable comprising a plurality of sheaves mounted in an arcuate path on a support frame; counter-balancing weights positioned above the support frame and rigidly connected thereto; and a suspension arrangement, connected at the center of the assembly, for providing rotation of the assembly about two perpendicular axes of rotation; and sensors are provided for determining downward force on the sheave assembly and the angle of the cable by monitoring the number of pulleys rotating.

Abstract: The present invention relates to an improved internal combustion engine which separates the compression stroke from the power generator. In particular, the invention utilizes a cam profiled power shaft of a shape to accomodate the new movement of the power pistons to suit the particular phase of the combustion process.

Abstract: An axial piston type internal combustion engine of novel three cycle variety, wherein the complete combustion process within the combustion chamber consists of three distinct cycles, accomplished over two distinct strokes of each piston, the three cycles being: the high pressure charging cycle, the power cycle, and the postive total exhaust expulsion cycle. The aspiration is controlled by a rotary disc valve, while the fresh gas charge is pre-compressed to high pressure by a separate high pressure charger. The conventional intake stroke and compression stroke, normally directly or indirectly carried out by the power piston in conventional two stroke or four stroke engines, is entirely divorced from the functions of the power piston and its power train components. Intended to replace conventional engines when high specific output, high power to weight ratio, and economy of operation are paramount.

Abstract: A cam operated internal combustion engine of piston type positive displacement variety, having novel piston-to-cam connecting means. The pistons are cam operated to optimize the aspiration, combustion and expansion process. Executed in axial and radial cam versions, with alternatively a two cycle, four cycle or novel three cycle mode of operation. The arrangements provide advantages in manufacturing and construction, as well as improved thermal efficiencies.

Abstract: A piston type internal combustion engine of novel three cycle variety, in which the intake and compression functions are divorced from the combustion cylinder entirely and are carried out by a separate high pressure compressor; with a high pressure charging cycle, a power cycle and an exhaust cycle carried out in the combustion chamber in a positive manner. The gas charge is pre-compressed to maximum permissible value and injected into a varying volume combustion chamber, without any appreciable change in pressure. Power output is varied by varying the initial volume of the combustion chamber. Executed in radial cam driven and crank driven versions. Intended to replace conventional variable output engines.

Abstract: An automotive engine having an automatically adjusted geometric compression ratio, wherein the charge is compressed to maximum permissible values under all throttle settings. This is achieved by a cylindrical valve carrier, raised or lowered by a screw jack, while valve stem contact is maintained by a fast acting hydraulic valve actuator. The compact arrangement provides an engine profile which is not significantly taller than a standard overhead cam engine.

Abstract: Disclosed is a water sampler device for collecting a sample of water at a desired depth, the water sampler device comprising a tubular member having at each end a rotatably mounted ball valve, a valve pulley mounted on the exterior of the tubular member and coupled to the ball valve for rotating the same, a center pulley mounted on the tubular member between the valve pulleys, an endless belt positioned around the three pulleys, an electric motor coupled to rotate the third pulley, electric circuitry for activating the electric motor and then deactivating the electric motor to open the ball valves at a desired level and then subsequently closing the ball valve at a level whereat the sample is taken.

Abstract: An apparatus for sensing the orientation of an inclinometer in both direction and magnitude for determining the velocity and direction of currents in a body of water having a magnetic north seeking sphere buoyantly supported in a housing. Implanted on the sphere is a plurality of tuned circuits of different resonant frequencies set at right angles to each other and a sense-drive winding or coil mounted about the housing. Upon applying a series of pulses of voltage to the sense-drive coil, the tuned circuits will oscillate with decaying amplitude at their resonant frequencies in the intervals between the pulses of voltage. The mean voltage across each of the tuned circuits is a measure of the amount and direction of tilt of the housing caused by the currents. The sense-drive coil senses these voltages across the tuned circuits and between the induced pulses of voltages, will transmit them to conventional recording equipment whereby a continuous determination of the currents velocity and direction are obtained.
