Abstract: A lubricating arrangement for the overhead camshafts of an internal combustion engine. The cylinder head assembly (15) is formed with wells (48) in which lubricant can accumulate during the running of the engine and which surround at least in part the camshafts (35,54). When the engine stops running, the wells (48) will retain lubricant so that the camshaft will be lubricated immediately upon start up. The wells (48) associated with at least one of the camshafts are formed at least in part by the bearing caps (44,45) that journal the camshafts (35,54). One camshaft is supported by a greater number of bearings than the other camshaft and the fastening means associated with the camshaft bearings of the camshaft having the greater number of bearings are smaller than those associated with the other camshaft so as to insure equal torque down.

Abstract: An electric motor comprises a laminated stator core (13) supporting windings (16) to define similar adjacent poles. A rotor (12) is mounted to rotate within the stator. The similar poles in a group define flux paths with adjacent pole groups. Thus the flux paths (20) required are restricted to those between adjacent dissimilar pole groups. In this way the material of the core between the flux paths can be reduced as it is not required to carry flux itself. This redundant portion of the core can be shaped to accommodate neighbouring components or to reduce the material of the core laminations.

Abstract: An electronic circuit provides a linear output from an amplitude modulated transmission device such as a semiconductor laser which has inherent distortion. The distortion of the nonlinear device is compensated by applying a predistorted signal equal in magnitude and opposite in sign to the distortion introduced by the nonlinear device. The input signal is split into two paths with primary part of the signal applied directly to the device, with a time delay to compensate for delays in the secondary path. A distortion generator in the secondary path generates intermodulation signals, the amplitude of which is adjusted to match the amplitude of the distortion of the nonlinear device. A tilt adjustment is made to compensate the amplitude of the predistortion for frequency dependence of the amplitude of the distortion. A adjustment of the predistortion signal is also included so that phase of the distortion signal generated is in proper phase relation with the distortion inherent in the nonlinear device. A push-push amplifier is used as a distortion generator, with bias current unbalanced to produce net odd order intermodulation products as well as even order intermodulation products of the fundamental frequencies.

Abstract: The detection of nucleic acids can be achieved with certain advantages in polymerase chain reactions by using primers in unequal concentrations. In particular, the molar ratio of a pair of primers is at least 2:1. Amplification of the nucleic acid of interest is carried out using standard reagents, but denaturation of the complementary products prior to detection is not needed. Detection is then accomplished using an enzyme-labeled reagent which will provide a colorimetric or fluorometric signal in the presence of the appropriate substrate.

Abstract: A sample of a hydrocarbon oil containing asphaltenes is chromatographically analyzed by forming a mixture of the oil with a weak solvent. The mixture is passed in contact with a column of a stationary phase of fine solid particles of fully functionalized material, followed by a weak solvent. The solvent, after recovery from the column, is analyzed for aromatics by UV-absorption of UV radiation in the range 200 to 500 nm. The absorbance of the UV light by the irradiated eluents across the UV wavelength range is monitored and the integral of absorbance is derived as a function of photon energy across the wavelength range. The magnitude of the derived integral in at least one time interval corresponding with aromatics in the eluent from the stationary phase is measured as an indication of the level of aromatics in the oil sample. The weak solvent may be followed by a strong solvent which, in turn, may be followed by a strong solvent which is modified by the addition of a hydrogen bonding solvent. The solvents are analyzed for saturates, aromatics, polar compounds and any asphaltenic materials by the combination of the UV-absorption measurement and a mass sensitive measurement which measures the combined level of the saturates, aromatics, polars and any asphaltenic compounds present. Equipment to perform the foregoing analysis is also described. The analysis can be used for evaluation of an oil and/or for on-line regulation of an oil refining process.

Abstract: In the determination of motion vectors for the blocks of a source image sequence, hierarchical search methods are usually applied by using a block-matching error criterion. The motion vector found in a search step is used as starting value for improvement in subsequent search steps. In the invention, at least two motion vectors, in which the error criterion is smallest, are determined in a first search step in an image with reduced resolution. These motion vectors are interpolated to sub-pel accuracy and brought to a size which has validity for the non-reduced image. In the second search step, the search is refined in a small area surrounding these motion vectors and the zero vector and the motion vector is determined, for which the error criterion supplies the smallest value. <IMAGE>
