Patent DE-19506006-A1 (DE)
Inventor: HELLMANN BERND DIPL ING
IPC: H02P25/26
Filed: 1995-02-17
Abstract: In order to increase the power of a three-phase asynchronous motor (1) with a slip ring rotor (3) in a drive with a variable speed of rotation and to reduce the amount of equipment required for that purpose, the motor (1) is fed at the stator side by a frequency converter (5) that regulates the stator voltage or current (IS) and the stator frequency (fS) and at the rotor side by another frequency converter (I) that regulates the rotor voltage or current (IL) and the rotor frequency (fL). The frequency converters (5, 9) are controlled by a controller (12) so that the motor power is distributed to a predetermined extent between both frequency converters (5, 9) and that a predetermined speed of rotation of the motor results from the stator frequency (fS) and rotor frequency (fL). In order to operate the motor (1) with high voltages and the frequency converters (5, 9) with low voltages, transformers (4, 8) are arranged between the motor (1) and the frequency converters (5, 9). In order to keep small the transformers (4, 8), the stator frequency (fS) and the rotor frequency (fL) never fall below a predetermined minimum frequency. The speed of rotation of the motor may be nevertheless regulated over small values all the way down to its standstill.
Patent DE-19509231-A1 (DE)
Inventor: KOBLINGER OTTO DIPL PHYS DR
IPC: H01L21/768
Filed: 1995-03-17
Abstract: A process is disclosed for applying a metallisation layer on an insulator and for piercing through-holes in the insulator with one and the same mask. A substrate (1) has a first (3) and a second (4) insulating layer on its surface (2), a covering layer (5) on the second insulating layer (4), a structured masking layer (6) on the covering layer (5) and metal-filled through-holes (7) that extend from the rear side of the substrate to its surface (2). The masking layer (6) is structured in such a way that it has openings in the areas located above the through-holes (7) and in the areas to be provided with a metallic layer (7). The covering layer (5) is pierced in the areas that are not covered by the structured masking layer (6) by a first etching process. The second insulating layer (4) is then laser ablated in the areas located above the metal-filled through-holes (7) by means of a dielectric mask. The first insulating layer (3) in the areas located above the metal-filled through-holes (7) and the second insulating layer (4) in the areas to be provided with a metallic layer (8) are then pierced at the same time by a second etching process. The through-holes (7) are thus completely freed from the first insulating layer (3), the second insulating layer (4) is completely removed from the areas to be provided with a metallic layer (8) and the first insulating layer (3) remains substantially intact on the surface (2) of the substrate.

Title: Ore material comminution
Inventor: PATZELT NORBERT DIPL ING
IPC: B02C23/12
Filed: 1995-04-04
Abstract: In a method for comminuting ore material, pre-comminuted ore material is subjected to material bed comminution in a material bed roll mill where it is further comminuted in the grinding gap between two rolls which press against one another under high pressure and revolve in opposite directions. Finely ground ore material is drawn off as finished prod., where the ore material is pre-comminuted in an autogenous mill and then classified into fractions of fine material, while the rest of the material is delivered to the material bed comminution. The classification is carried out with the aid of a screening device, a screw classifier or the like. Wet classification is carried out also in a screening device in which the fine material as well as any plastic and sticky material fractions are washed out of the ore material sliding over the screen by the spraying of fluid such as water, and drawn off as screenings, whilst the remaining material as screen residue is subjected to material bed comminution. The fine material is finely comminuted to a predetermined prod. in at least one fine grinding mill or fine grinding installation. The rest of the comminuted prod. from the material bed comminution which has not been recirculated is reground to a predetermined fineness of the finished prod. in a fine grinding stage before being drawn off as finished prod..  The fresh ore material is pre-crushed in a primary crusher before being fed into the autogenous mill.

Title: Solar cell arrangement with maximum light utilisation
Inventor: MEYER-STAUFENBIEL TORSTEN ING
IPC: G01W1/12
Filed: 1995-04-04
Abstract: The arrangement (10) has multiple, e.g. four, rectangular cells and perform three functions: it can monitor brightness; it can supply power to devices such as roller shutters; and it can produce a signal when the sun's position is related to a time. The sunlight falls on the solar cells (11-14) in different ways because of the use of screening elements (15) between the individual cells. A combination of different signals is produced in an evaluation unit which detects the sun's position. By connecting this to a control unit, any solar powered equipment, e.g. blinds, can be operated directly, depending either on the light intensity or on the sun's position, and not on the operation of a time switch.

Title: Control system for PWM AC-to-DC converter
Inventor: NAKAZAWA YOOSKE
IPC: H02M7/162
Filed: 1995-08-24
Abstract: A control using an open or closed loop process to obtain DC from the single phase AC input. It has a circuit into which are input the instantaneous output direct voltage, a reference direct voltage, an instantaneous input alternating current, a supply voltage and a supply phase angle, thereby generating a reference alternating voltage.  A triangular waveform generator (2) receives the supply voltage phase angle and generates the triangular waveform.

IPC: G01D5/244
Filed: 1996-03-19
Abstract: The invention relates to a tracking detection system of electrical servomotors with incremental position detection in particular for servomotors in motor vehicles. To determine the position, said tracking detection system is provided with a microcontroller with an autoalarm device. Said microcontroller can be moved from run mode (B1) to sleep mode (B0) to reduce the average current intake, and after a predetermined period of time (e.g. 1mm) can be automatically moved back to run mode (B1). Said microcontroller samples the position signals (HS) of position transmitter when it is in run mode (B1) at particular sampling points (11, 12), and is moved between the required sampling points for a particular, calculated period of time in sleep mode (B0). The particular, calculated period of time is calculated from a detected edge change of the position signal.
