IPC: G01R27/02
Filed: 1980-09-11
Abstract: Disclosed is a method to detect the rotor resistance of an asynchronous machine, wherein a first vector attached to the emf of the machine is determined by computing the emf-vector or the flux vector from the stator voltages and the stator currents; wherein a flux attached to an arithmetic model circuit is determined, whereas the arithmetic model circuit uses the stator currents and the rotor position of the machine and an adjustable model parameter for the rotor resistance as basic quantities and imitates the dynamic events leading to the magnetic flux of the machine; wherein a difference of two quantities is determined, wherein the first quantity represents a defining quantity of the first vector attached to the machine and the second quantity represents a respective defining quantity of a second vector derivable from the imitated flux and that the setting of a model parameter is varied until the value of the difference is a minimum, whereas the model parameter corresponding to the minimum of the difference is regarded as the resulting rotor resistance of the machine.

Patent DE-3100788-A1 (DE)
Title: Continuous dehumidifying apparatus for gases
IPC: F24F3/14
Filed: 1981-01-13
Abstract: The invention relates to a continuous dehumidifying apparatus for gases which includes two main flow channels, of which one conducts the gas to be dried and contains a filter device, while the other flow channel serves as a regeneration circuit, in order to regenerate the used filter device in sections. The regeneration circuit conducts a preferably heated regeneration gas either in the direction of the gas stream to be dried or in a counter-current direction. In order to ensure, in the region of the filter device, a complete separation of regeneration gas from the gas to be dried, the filter device is made up of at least one perforated disc and a plurality of filter cartridges which are arranged in the perforated disc at the same angular separation from each other. The arrangement is such that at least one of the filter cartridges can be connected into the regeneration circuit, while the other filter cartridges lie in the flow channel which conducts the gas to be dried. According to Fig. 1, the perforated disc (8) is equipped for example with four filter cartridges which, with the aid of two opposing hoods (6, 6'), can be connected into the regeneration circuit. <IMAGE>

Title: Method for continuously moving a multiplicity of successive documents, and apparatuses relating thereto
Inventor: CONE CLENDON W
IPC: B65H5/24
Filed: 1981-05-15
Abstract: An apparatus for continuously feeding and aligning documents for further processing at a point at which they are fixed by means of adhesive to a backing sheet, comprises a first belt device (16) which receives, moves and aligns the documents, and a multiplicity of stop elements fastened on the said device. Each stop element is situated at the same distance from the adjacent one along the length of the first belt device. A second belt device (18) cooperates with the first belt device to move and align the documents and is arranged above the first belt device and moves in the same direction as the latter. An alignment zone is therefore defined by the two belt devices. The second belt device has at least a first set of positioning elements which are fastened at predetermined intervals along the length of the second belt device, in such a way that they enter the alignment zone shortly after the stop elements. A positioning element is therefore placed above the leading part of each document. Each positioning element of the first set has a contact device which exerts a vertical pressure on the moving documents, and a horizontal positioning device which keeps the documents horizontally positioned as they move through the apparatus. The documents and the supporting sheet are in continuous movement from the moment at which they are fed to the moment at which the final arrangement of supporting sheet, with documents fastened to it, is folded over at the end of the processing sequence. <IMAGE>
