Patent EP-0416263-A1 (EP)
Inventor: SCHLEUTER WILLIBERT DR ING
IPC: B62D101/00
Filed: 1990-07-26
Abstract: A method for acting on the damping of a power steering system, in particular of a motor vehicle, is proposed, in which the damping of the power steering system can be determined as a function of the actuation direction of the steering system, in particular as a function of the direction of the power flux. At the same time, the restoring forces from the wheels acting on the steering system can be damped in their effect differently from steering movements carried out by the driver. The damping of the two actuation directions can be adjusted largely independently of one another. <IMAGE>

IPC: B65G21/10
Filed: 1990-09-28
Abstract: In a belt conveyor (10) with two conveying parts (11, 12) forming an adjustable angle with each other and a continuous conveyor belt (25), the conveying parts (11, 12) are interconnected via an articulation pin which extends at a distance from the upper section position (28) of the conveyor belt (25). As a result, the overlapping of side cheeks (44, 45), which extend on both sides along the conveyor belt and project beyond its upper section position (28), can be preserved in the entire adjustment range and the formation of gusset-like openings can be avoided. One of the deflection rollers (38) guiding the continuous conveyor belt (25) is mounted movably in the longitudinal direction of the conveyor belt and supported elastically yieldingly in such a manner that automatic length compensation (40, 41, 42) takes place during pivoting of the conveying parts towards one another.

Abstract: A video signal compression apparatus in which a video signal having a non-matrix pixel arrangement is separated (2) into a plurality of partial images each having a matrix pixel arrangement. The partial images thus separated are interpolated (3,) into those containing low-frequency components and those having high-frequency components. The partial images having low-frequency components are coded by an orthogonal transformation (5), while those having high-frequency components are coded by a non-linear quantization or orthogonal transformation (6). The amount of data is adaptively assigned (7, 8) from the code length of the partial images having high-frequency components to those having low-frequency components, thus effectively utilizing the orthogonal transformation coding which has a great compression on a video signal having a non-matrix pixel arrangement. Further, by virtue of a comparatively small amount of data for the signal of high frequency region, the signal of low frequency region having a comparatively great amount of information can be assigned with a greater amount of data thereby to improve the compression efficiency.

Abstract: Devices, processes and compositions are provided for effective separation of cells from a mixture of cells, where depletion or positive selection may be employed to provide a cellular population of interest. Of particular utility is the separation of cells from peripheral blood mononuclear cells, where members of the lymphoid or myeloid lineages may be isolated and used for research, diagnosis or therapy. Also of interest are cellular separation from bone marrow, tumor suspensions or lymphoid tissue suspensions, where cells can be isolated and used for a variety of purposes. The separated cells may be homogeneous, free of exogenous biologicals, viable, capable of replication and exhibit their full complement of biological activities. Multiple phenotypes can be captured simultaneously. Captured cells can be specifically activated with cytokines and antigens to provide cells which are MHC restricted and have antigen-specific effector functions.

Abstract: A stator vane stage (54A) in a split-case, variable geometry axial flow compressor (30) includes two 180-degree spoke-like arrays of stator vanes (56) on upper and lower case halves (16,18) of the compressor case (12) and a pair of unitary, 180-degree arc shroud ring segments (84,86). Each stator vane (56) has a pivot shaft (64) at one end rotatably supported in a radial bore (70) in the corresponding case half by a bushing (74), and has a cylindrical vane button (66) at the other end. Each shroud ring segment (84,86) has a corresponding plurality of cylindrical vane button sockets (100) in an outer surface (88,94) thereof, each of which rotatably receives a corresponding vane button (66). The spoke-like array of the stator vanes (56) rigidly positions the shroud ring segments (84,86) relative to the compressor case (12). To assemble the shroud ring segments (84,86) to the stator vanes (56), the shroud ring segments (84,86) are first resiliently squeezed radially inwards, whilst the vane buttons (66) are sequentially inserted into the corresponding vane button sockets (100), and then are released to spring back to their true 180-degree arc shapes in which they are retained on the stator vanes (56).

Title: Heterodyne stage having precise closed-loop control of the amplitude of the injection signal thereof.
Inventor: GRANDFIELD WALTER JOSEPH
IPC: H03D7/12
Filed: 1990-01-05
Abstract: A heterodyne stage of a receiver which includes a conventional mixer circuit and local oscillator circuit further includes a differential amplifier circuit which measures the amplitude of the injection signal generated by the local oscillator circuit and controls it precisely to a desired reference level by adjusting the current bias supply to the local oscillator circuit within a banded range to ensure start-up of the local oscillator upon energization and to protect against loss of injection signal under all operating conditions. The differential amplifier circuit provides for a precise amplitude reference setting and sufficient closed-loop gain for controlling the amplitude of the injection signal with a minimum of error between the measured and reference values.
