Title: Process for treating heavy oil
Inventor: KYDD PAUL H
IPC: F02B3/06
Filed: 1981-10-21
Abstract: Crude shale oil, which contains compounds capable of precipitation, such as iron and arsenic, is preheated up to a temperature below the precipitation temperature and then mixed with hot recycled hydrogen and oil and catalytically hydrocracked in a reactor with a boiling catalyst bed. The metal compounds are precipitated on the catalyst in the reactor, from where they are withdrawn together with the spent catalyst which is replaced by a fresh catalyst. The outflow stream of the reactor is further hydrogenated in a fixed-bed catalyst reactor, in particular usually at extreme conditions from 416 to 443 DEG C (780 to 830 DEG F) and a hydrogen partial pressure from 124.1 to 172.4 bar (1800 to 2500 psig). The resulting material is phase-separated and distilled to give a jet and diesel engine fuel oil product which meets military specifications, while pure hydrogen and heavy oil streams are re-heated and recycled to the boiling-bed reactor.

Title: Lifting device
IPC: B64C31/04
Filed: 1981-11-12
Abstract: The invention relates to the utilisation of the power for low-loss generation of the drive in aircraft driven by muscle power. The available power is supplied to the system in the form of potential energy, by lifting a mass element and hence the total centre of gravity while obviating the power losses which occur, for example, in the case of propeller drives and the complex kinematics and mechanisms which are required in the case of reciprocating drives. One possibility for use is to improve the effective gliding angle, or to reduce the sink rate of hang gliders and gliders.

Title: Root-mean-square value measurement
Inventor: LOBJINSKI MANFRED DIPL ING
IPC: G01R19/02
Filed: 1982-06-11
Abstract: For measuring the root-mean-square value, a circuit is specified which operates in accordance with the principles of stochastic mathematics and by means of which the root-mean-square value can be measured within a greater frequency range and with a simpler circuit than in the known method. In this arrangement, the voltage to be measured is directly supplied to the input of a comparator which is thus the switching element which determines the upper cut-off frequency. The root-mean-square value is calculated in a subsequent microcomputer, the arithmetic operations of which relate to counting results which are obtained by sampling at the comparator output.

Title: Device for optically scanning markings
Inventor: SIEBE ULRICH DIPL ING
IPC: G06K7/10
Filed: 1982-09-04
Abstract: In this device, the light receiver is arranged in a measuring bridge circuit with a constant current source. This limits the current through the light receiver right from the start. In a further development of the invention, it is provided to form from the difference voltage derived from the measuring bridge circuit a reference voltage in that the difference voltage is detected whenever it assumes its lowest value and is stored again for forming the respective reference voltage, and to supply this reference voltage to a differential amplifier which is also supplied with the difference voltage. In this manner, output signals suitable for digital processing can be created. Finally, it is provided to control the current through the light transmitter in dependence on the reference voltage which is derived from the difference voltage of the measuring bridge in order to compensate for different setting-down angles of the device, which is preferably constructed as a light pen.

IPC: H02P27/06
Filed: 1982-09-16
Abstract: The invention relates to an excitation circuit for a frequency converter, having a DC intermediate circuit for supplying asynchronous motors, in particular standard motors. The object of the invention is to design an excitation state using known electronic means, in which the matching of the voltage to the frequency can easily be adjusted, is correct at all operating points and in which the adjustments of the various drive parameters, such as the characteristic response U1 = f(f1), the frequency increase at low voltages, and the starting frequency do not mutually influence one another. A further object of the invention is for it to be possible to install this excitation circuit easily in existing installations by the replacement of assemblies. The object of matching the characteristic is achieved with the aid of an electronic circuit of a characteristic rotator which rotates the excitation characteristic about a freely selectable operating point (Fig. 7). According to Fig. 8, said rotator consists of an amplifier 5 for positioning the rotation point, of three amplifier groups 2, 3 and 4 for rotating the characteristic and of a further two amplifier circuits 6 and 7 for correcting the characteristic response. According to the invention, the characteristic rotator is supplemented by a further circuit for rotation point localisation in accordance with Fig. 10, in which simple localisation and recognition of the operating point about which the characteristic is rotated is possible with the aid of light-emitting diodes.

Patent DE-3242260-A1 (DE)
Title: Heat exchangers
Inventor: KOTTHAUS HEINZ DR ING
IPC: F28F1/28
Filed: 1982-11-15
Abstract: The invention relates to heat exchangers, in particular for heating or cooling the engines of motor vehicles whose engines are liquid-cooled, consisting of a number of metallic gills which contain openings, the rim of each opening being deformed into a collar and it being the case that after the assembly of a multiplicity of gills to form a heat exchange block the collars of adjacent gills, which are assigned to one another and extend in the same direction, form continuous pipelines which extend perpendicular to the gills. Such brazed heat exchanger blocks require for their production a substantial technical outlay such as, eg, brazing furnaces having a specially set-up brazing atmosphere or vacuum brazing devices. In accordance with the invention, these substantial disadvantages are avoided when there are set over the outsides of the collars or into the insides of the collars, rings of preformed adhesive which have a solid or dry-elastic state at the processing temperature. <IMAGE>

Title: Elevating gate with unidirectional hydraulic cylinder
Inventor: KILGUS KARLHEINZ
IPC: B60P1/44
Filed: 1983-01-14
Abstract: A unidirectional hydraulic cylinder (20) has a cylinder space with a lower cylinder space region (25) of small diameter and an upper cylinder space region (26) of wider diameter. An actuating member (27 + 28) is guided through the upper wall (23) of the cylinder space in a sealed manner. The lower part (28) of the actuating member has a diameter (DK) which corresponds to the diameter (DU) of the lower cylinder space region (26). The upper part (27) of the actuating member has a smaller diameter (DS) than the lower part. Hydraulic fluid is fed to the lower cylinder region (25) via a fluid line (22).   In the event of high forces on the actuating member, it yields hardly at all if its lower part (28) is in the lower cylinder space region (25). Given a constant delivery volume, the actuating speed in the upper region is greater during the movement of the actuating member than in the lower region. Cylinders according to the invention can be used with particular advantage as closing cylinders on elevating gates. <IMAGE>
