Patent DE-4011588-A1 (DE)
Inventor: KELLER LIBOR DIPL ING
IPC: G01R33/02
Filed: 1990-04-10
Abstract: In a materials testing method employing measurements of the magnetic flux induced in a sample of the material under test by an applied field, an operating period is divided into n (i.e. 2 or more) intervals. During these intervals, determinations of the intensity of the applied field are carried out to give n values that are formed into an n-dimensional vector representing field intensity. A corresponding set of n values of the flux induced in the material is obtained and formed into a further n-dimensional vector representing induced flux. Analysis of the vectors yields information on structural and mechanical properties of the material. A computer 8 controls units 1, 3, 6, 7 via data-buses 9, 10 in equipment suitable for carrying out the method. <IMAGE>
Patent DE-4011711-A1 (DE)
Inventor: GRABOWSKI WALTER
IPC: H02G3/16
Filed: 1990-04-11
Abstract: The installation concerns an electrical house-wiring system in which plug blocks are mounted in sockets in the floor by virtue of their special design. This makes it possible not only to combine these sockets mechanically by simply plugging in a usually three-pin bridge unit in the form of a pin-and-socket connector, but also to combine them electrically without any loss of time. To this end, each unit in a combination has facilities for directly connecting up appliances to be installed. The appliance connection can take the form of a pre-assembled three-wire cable harness. In addition, at least one take-off line can be taken from each of these combined sockets to supply power to other socket systems. In general, with this installation technique no wiring work is necessary on the building site to connect up the individual sockets within a combination to their power supply. The generally individually laid connector clips previously used are no longer necessary. Sockets of this type can be used not only as appliance sockets or appliance connector sockets but, if required, also as pure connector sockets.

Title: Squirrel cage induction motor speed control method - having triac-controlled AC supply with suppression of regular periods of waveform and phase gate control of half-waves
Inventor: KONSTANZER MICHAEL DIPL ING
IPC: H02P1/44
Filed: 1991-09-13
Abstract: The method involves regulating the speed or input power to an induction motor to suppress regularly a whole period of the AC supply, e.g. the 1st, 2nd, 4th, 5th, 7th, 8th, half-waves. The remaining stream of alternating half-wave pulses are then shaped by phase-gate control of thyristors or triacs. During the "missing" periods of the AC supply, the motor speed is sampled and used in the control of stator current. When the motor is initially started for a short time (set by the user) the effective value of the AC voltage is increasing using the phase gate control. The motor current is measured and the value is used to alternate between half-wave excitation or continuous full-wave excitation. ADVANTAGE - Less expensive then using rectifier-inverter systems; improvement in efficiency.
