Title: Ultrasonic welding of aluminium to other metals - where anvil sonotrode is briefly activated after welding so aluminium does not adhere to anvil
Inventor: MOLL HELMUT ING GRAD
IPC: B23K20/10
Filed: 1980-07-10
Abstract: An Al workpiece is laid on an anvil sonotrode; and a welding sonotrode is used to press another workpiece on the Al. During the welding process, only the upper, welding sonotrode is activated and, after welding, the upper sonotrode is removed. The anvil sonotrode is then briefly activated. The method prevent Al workpieces from sticking to an anvil during mass prodn. Although an oil or similar substance can be used as a sepg. agent it makes the workpieces dirty and is unsuitable for mass prodn. Used esp. for welding thin sheets together, e.g. Ni/Al; Cu/Al/ steel/Al/ or Al/Al; e.g. Ni/Al joints for He-Ne laser tubes, or Cu/Al joints on Al cases for suppression filters.

Title: Control system for direct converter fed synchronous machine - mathematically processes stator supply current and rotary speed values
Inventor: GRUMBRECHT PETER DIPL ING
IPC: H02P6/00
Filed: 1980-11-29
Abstract: The method of regulating a direct converter fed synchronous machine, uses a rotary speed control from which are obtained the polarity and amplitude of a value corresponding to the stator supply current. This value and a second value are applied to a machine model. The second value is a value obtained from the rotary speed by using a characteristic curve generator or the resulting magnetisation from the voltage and current. The quadrature of these values and their sum by extracting their square roots are determined, and also the result of dividing the first value by the second by successive arc/tan formation of the control angle between imaginary pole voltages and input currents are obtained. The control angle measured against the measured angle is obtained from a desired value former for the three normal sine values shifted by 120 degrees. To evaluate these sine values against the current supply values, a desired value system for the instantaneous values of the three stator currents is used.

Abstract: A pen has a head attachment (2) which is screwed, by means of an insertion pipe (201), into the upper region of a shaft tube (1) so that it can be moved in the axial direction. A writing tip (3) extends removably through the head attachment, it being possible to adjust, as required, the length of the upper region (301) of the writing tip which projects from the head attachment. Formed on the outer circumferential surface of the insertion pipe (201) is a projection arrangement (202) which presses against the inner surface (101) on the upper region of the shaft tube. The insertion pipe has, furthermore, one or more slits (203) close to its end and extending in the axial direction, these enabling the insertion pipe to be deformed when it is screwed into the shaft tube. An ink-guiding core (5) is fixed in the shaft tube and is connected to an ink reservoir element (4). A collector (6) having a central aperture is placed on the top of the ink-guiding core and has a diameter which is adapted to the diameter of the writing tip. The central aperture has a conical widening in its upper region and, on its base side remote from the conical widening, has an aperture of larger diameter for receiving the ink-guiding core. The base region of the writing tip which projects downwards from the head attachment (2) extends through the collector (6) into the ink-guiding core (5). The effect of this arrangement is that the writing tips (3) can be exchanged without problems, and also that the length of the writing tip projecting upwards from the head attachment can be conveniently adjusted. Writing tips of relatively short length can be used for the pen. <IMAGE>
