Abstract: A two-stroke internal combustion engine has a duplex piston (48) slidable in co-axial cylinders (18,28). The engine has an inlet (15) for air/fuel mixture, an air inlet (29) and an exhaust outlet (36), and the combustion chamber has air inlet ports (32) and air/fuel transfer ports (34). The piston is arranged to pump a fresh air charge into the combustion chamber slightly in advance of the air/fuel charge to assist in scavenging and avoid unburnt fuel being passed directly to exhaust. The crankcase may or may not be used for charge compression.

Abstract: A shaft seal arrangement of a turbocharger (1) for an internal combustion engine having a throttle valve disposed upstream of a compressor of the turbocharger. First and second seal rings (12,13) are fitted on a cylindrical thrust spacer (11) fixed on a rotatable shaft (2) on which turbine and compressor wheels (4,3) are mounted. The seal rings (12,13) are spaced from each other and positioned between the compressor and bearings (6) for the shaft (2). An annular air chamber 14 between the seal rings (12,13) is supplied with atmospheric air through an air supply passage (15). The cross-sectional area of the air supply passage (15) is such that a pressure difference between the air chamber (14) and the bearing side is prevented from exceeding an experimental pressure difference value at which oil leak from the bearing side to the compressor side begins, thereby effectively avoiding oil leakage even in an engine operating condition in which the throttle valve is fully closed.

IPC: H02K41/06
Filed: 1990-01-24
Abstract: A trochoidal speed reduction mechanism forms an integral part of the stator and rotor of an electric motor so that a slow-speed high-torque output is produced without having any high speed rotating component in the motor. A rotor has an epitrochoidal contour with a predetermined number of lobes. Positioned around the rotor are two non-rotating orbiting stator-rings, phased 180 degrees apart, each provided with a number of rollers equal to the number of lobes on the rotor plus one. The rollers are rotatably mounted on the inner surface of the stator-ring and are in continuous contact with the epitrochoidal contour of the shaft rotor. The non-­rotating orbital movement of the stator-rings is produced by magnetic forces from a series of stator windings arranged as magnetic poles around the stator-rings. This action causes the rotor to rotate at a speed equal to the orbiting speed of the stator-rings divided by the built-in speed reduction ratio. Because the two stator-rings are orbiting 180 degrees apart, the orbiting masses and the torque on the rotor are balanced. The current flow through the stator winding, the sequential timing, the direction of rotation and the speed are all controlled by conventional solid state circuitry.

Abstract: A method is provided for predicting a property of a matter of biological origin, such as biological fluid, containing water, where the biological matter may be approximated to contain two compartments where one compartment has a proportionally larger or smaller amount of water than the other compartment having the property of interest. The method involves establishing a training set in the near-infrared (NIR) region with independent quantification of the property of the matter using known techniques. The training set is mathematically analyzed according to a correlation developed by regression analysis after employment of a pre-processing technique. The result is a mathematical transformation equation which quantitatively relates spectral intensities at specific wavelengths to the property of interest. This transformation equation may be applied to unknown samples so as to predict their properties, thereby eliminating need for the reference method, except for validation and recalibration. The method provides rapid and accurate prediction of the property of the unknown sample, which may be the property of hematocrit or hemoglobin concentration in whole animal blood. The pre-processing technique may be the transformation of the spectra using a multiple derivative calculation, such as computing the second derivative of the several spectra of known and unknown samples.
