  • Method of producing dicarboxylic acids suitable for synthesis of polymers or polyamides
    Patent number: 6455715
    Abstract: A method is described for producing saturated dicarboxylic acids with a chain length of C6 to C21 or the corresponding diamidic dicarboxylic acids from fatty acid cleavage of unsaturated fatty acids or the bis-fatty acid diamides of these unsaturated fatty acids by oxidative ozonolysis and subsequent separation and purification of the dicarboxylic acids, whereby after oxidative ozonolysis, the reaction products are dissolved at a high temperature in a carboxylic acid or a mixture of several carboxylic acids with a medium chain length of C6 to C12 or esters of short-chain alcohols of these carboxylic acids as the recrystallization solvent.

  • X-ray tube with rotating anode core
    Patent number: 6453011
    Abstract: Conventional x-ray tubes are designed as stationary or rotating-anode tubes. While the former are restricted in output, the latter are of complicated design. An x-ray tube is provided having an anode comprising a stationary shell and a rotating core mounted therein. Consequently, it is more compact than a rotating-anode tube and permits higher focal spot loads than a stationary-anode tube. The tube can be used for imaging procedures in medical diagnostics and in material testing.

  • Photoelectric position measuring device
    Patent number: 6445456
    Abstract: In a position measuring device, a scale is embodied as a phase grating on which several partial beams impinge and are diffracted and caused to interfere with each other in the scanning unit. The entry angle (&agr;) of the partial beams corresponds to the Littrow angle, so that the diffracted partial beams of ±1st diffraction order are diffracted at the same angle &bgr;=&agr;. The diffraction efficiency of the scale is particularly great if the flanks of the bars of the scales are at an angle of approximately 70° with respect to the measuring direction, i.e., if the bars and gaps are embodied to be trapezoidal in cross section.

  • Process and apparatus for the control of the light distribution of a headlight arrangement of a vehicle
    Patent number: 6443603
    Abstract: A process and apparatus are provided for the control of the light distribution of a headlight arrangement of a vehicle with at least one first light sensor which senses light emissions acting on a driver from the field of vision in the direction of travel for various areas of the field of vision. A comparator device compares the intensity of the light emissions for each area with a threshold value. A control device controls the light distribution of the headlight arrangement as a function of a signal of the comparator device. In order to provide an improved process and an improved apparatus for the control of the light distribution of a headlight arrangement of a vehicle, it is proposed for the light distribution in the sense of an increase of the illumination of the edge of the road of the driver's own side of the road to provide a turn-off delay combined with a deadtime connected before it.

    Abstract: A cylinder head for a valve-controlled internal combustion engine with a cylinder head housing, in which there are bearing blocks for the inlet or outlet camshaft. At least one camshaft has a camshaft adjuster, by way of which the position of the drive wheel of the camshaft can be changed relative to the axis of rotation of the camshaft. At least the bearing block, which is provided next to the camshaft adjuster and is intended for the camshaft, exhibits a segment, whose width is reduced owing to a recess for the screw connection of the cylinder head housing. The bearing site, arranged next to the camshaft adjuster, provides a bearing sleeve for the camshaft, in such a manner that the segment of the bearing block that is provided with a reduced bearing block width is expanded to the actual bearing block width. The sleeve exhibits openings to supply oil for the camshaft adjuster.
