Inventor: STUEBS ALBERT
IPC: F02B1/04
Filed: 1984-07-24
Abstract: A device for measuring the intensity of knocking for a spark ignition engine with a knocking signal circuit. The technical problem is the provision of a device for measuring the intensity of knocking which indicates, for a measurement cycle which comprises a preadjustable number of operating cycles, the average number of knocking pulses and the number of knocking pulses which exceed a preadjustable intensity threshold. An oscillator (10) generates counting pulses. A preadjustable cycle counter (1) counts the operating cycles of the spark ignition engine. An analog-to-digital converter (7) converts the analogue signal of the knocking signal circuit (5). The counting input of a decrementer (8) which can be preadjusted by the output signal of the analog-to-digital converter (7) is connected to the oscillator (10) and the output (24) conducts a H level during the counting of the oscillator pulses and an L level when the zero counting stage is reached. The load input (14) of a preadjustable divider (13) is connected to the output (24) of the decrementer (8) and the counting input (25) is connected to the oscillator (10). A counter storage stage (15, 16) is connected to the output of the divider (13). The load input (26) of a preadjustable decrementer (18) is connected to the output (24) of the first-mentioned preadjustable decrementer (8) and the counting input (27) of the said decrementer (8) is connected to the oscillator (10).

Title: Drive circuit for power semiconductor which can be turned off.
Inventor: JUNGE GUENTER DIPL ING
IPC: H03K17/732
Filed: 1985-03-29
Abstract: In the case of a circuit arrangement for the turn-off control circuit of a GTO thyristor (GTO), a turn-off pulse is produced by switching a first auxiliary-voltage source (U2) and is transmitted in a floating manner via a transformer (T2) which is connected between the control connection (G) and cathode (K) of the thyristor (GTO) and is decoupled by means of diodes (D1...DN) from the turn-on control circuit (1) of the thyristor (GTO). In the case of high-power thyristors which can be turned off, it is necessary to make the reverse blocking voltage, which is required for blocking the thyristor (GTO), available for approximately 50  mu s to 150  mu s. For this purpose, the transformer (T2) is connected to a further circuit, which has a second auxiliary-voltage source (U3) and magnetises the transformer (T2) to be negative with respect to the magnetisation as a result of the turn-off pulse. The transformer (T2) is thus in the process premagnetised by the further circuit in such a manner that an adequate voltage/time integral is available for transmitting the turn-off control voltage. <IMAGE>

Title: Fast-running magnetically supported rotor whose supporting forces are produced by the electrical machine which is integrated with the rotor
IPC: H02K7/09
Filed: 1985-06-29
Abstract: In order to achieve a structurally simple arrangement in the case of a magnetically supported rotor, the electrical machine for coupling the energy in and out is designed such that it can also carry out the supporting function. A split into two magnetically mutually independent units, an axial field arrangement and a radial field arrangement, is provided for this purpose. In consequence, it is possible to carry out the control of the support of the rotor with the aid of the field setting of the machine in 5 degrees of freedom. A continuously acting force in one direction is in this case assumed in the axial direction. In order to control the normal force, the machines are each divided into 4 separately controllable winding quadrants whose energy conditioning is carried out by invertors. The normal forces are controlled by varying the phase angle of the current distribution, while the drive force is determined by the magnitude of the current amplitude. In this way, a very compact structural form is achieved for the entire unit, together with high energy conversion quality and minimising of interactions between the subsystems which control the magnetic field.

Title: Universal polarisation microscope
Inventor: BERGNER JOACHIM
IPC: G02B21/18
Filed: 1985-10-19
Abstract: The universal polarisation microscope according to the invention is applied in studying crystalline materials or substances. The aim of the invention is a microscope in which a rapid change between a plurality of methods of microscopic study is possible in conjunction with a constant viewing height. The object to be achieved consists in guiding the beam path in the microscope in such a way that it is possible for all the required optical components to be brought quickly and without complication into the beam path for at least two methods of investigation. The object is achieved when inside a tube which can be coupled to the microscope as a closed component the beams which image the object are guided to a common intermediate image plane optionally on two different intertwined imaging loops on which the imaging beams are physically influenced in different ways. From this plane, they are simultaneously guided via separate optical systems to an observation tube with eye pieces and a photometric tube with a photoreceiver.

Abstract: A portable planer is proposed which has an essentially circular-cylindrical planing tool (16) arranged in a housing (10) and fastened to a motor-driven shaft (11) running transversely to the planing direction. An exit sole plate (40) at least partly closing off the housing (10) at the bottom is attached behind the planing tool (16) tangentially to its flight circle, and an entry sole plate (57) displaceable parallel to the plane of the exit sole plate (40) is provided in front of the planing tool. The shaft (11), projecting on one side from the planing tool (16), is rotatably mounted only on this side of the planing tool (16), as a result of which the opposite end face of the planing tool (16) points freely outwards through a corresponding recess (24) in the housing (10). In this way, a simple and quick tool change is guaranteed on the one hand, and on the other hand planing can be carried out right into corners and edges by means of a portable planer of this type. <IMAGE>
