Title: Variable transformer with an electronic controller
Inventor: RAUPACH FRIEDRICH DR ING
IPC: H01F29/02
Filed: 1982-04-22
Abstract: The invention relates to a variable transformer having a primary winding (fixed winding) which is arranged around one or more transformer cores and, magnetically coupled thereto, secondary windings (variable windings), and having an electronic controller in order to achieve a secondary voltage which is at least approximately continuously variable. In order to achieve voltage regulation in such fine steps that a step width of 1% is not exceeded, the secondary windings (3) are constructed as winding groups (3a to 3e), which are electrically isolated from one another, with numbers of turns in the ratio of an increasing infinite numerical sequence. The individual voltages induced in the individual winding groups (3a to 3e) can in each case be connected together either in the same sense or in with respect to senses so that any desired voltage from the voltage value zero to the voltage limiting value can be set by connecting all the winding groups (3a to 3e) one behind the other, with the voltage of the winding group (3a) having the smallest number of turns as the voltage interval. <IMAGE>
Patent DE-3225949-A1 (DE)
Title: Stepping motor
Inventor: KANIA GEORG
IPC: H02K41/00
Filed: 1982-07-10
Abstract: The subject-matter of the application is a stepping motor by means of which very small angular steps can be carried out. It is based on a known stepping motor which operates, for example, on the swash-plate principle in which a circular contact surface (11) of a rotor (6) is rolled off, as a result of the operation of electromagnets (2, 3), on a circular contact surface (4) having a somewhat shorter length of the stator (1). According to one embodiment, the rotor (6) carries a further contact surface (12) which, on operation of a further electromagnet arrangement (17, 18), is rolled off on a contact surface (15) of an output drive arrangement (14) which is supported such that it can rotate. The track length of the contact surface (12) on the rotor side is somewhat longer in this case as well. In the case of successive driving of the electromagnets (2, 3 and 17, 18) of both electromagnet arrangements in the same rotation sense, one rotation of the output drive arrangement (14) with respect to the stator (1) is then obtained per revolution of the drives, which rotation corresponds to the difference between the length differences. <IMAGE>

Title: Pulsed radar equipment with digital Doppler evaluation
Inventor: RITTER GERHARD DIPL ING
IPC: G01S13/58
Filed: 1982-09-29
Abstract: The progression of the phase of the echo signals originating from a target from receiving period to receiving period is evaluated. The phase difference ( DELTA  zeta ) from receiving period to receiving period, containing information on the Doppler frequency, is averaged by means of low-pass filters (10, 11), in accordance with the target dwell time. The phase difference is determined in polar coordinate form and these differences are averaged in x-y coordinate form. A total of three coordinate transformation processes are then necessary since the input information is usually available in x-y quadrature coordinates (I, Q) and the output information containing the average Doppler shift of a target must have polar coordinate form. From the average Doppler shift, the radial speed of the target can be determined. The subject- matter of the invention can thus be applied to radar equipment which is to be equipped or retrofitted with a target speed determining system. <IMAGE>
