Title: D=A converter with increased precision - multiplies input by factor less than one when limit is exceeded
Inventor: ROEHRLE JOSEF ING GRAD
IPC: H03M1/18
Filed: 1979-02-21
Abstract: The d-a or a-d converter has its input signal multiplied by a factor less than one when that input signal exceeds a given limit. The output signal is multiplied by the reciprocal of this factor. Several limits may be provided such that when the limits are exceeded the input signals are multiplied by factors that decrease as limits increase. The digital signal is multiplied by the factor by using displacement in a shift register. The analog signal is multiplied by switching the feedback resistors of an operational amplifier. The converter's precision in converting small signals is therefore increased.

Title: Push=pull chopped voltage regulator - maintains steady output voltage by comparing voltage-time ratios of two conductive periods of switching transistors
Inventor: KALFHAUS REINHARD
IPC: H02M3/335
Filed: 1979-04-26
Abstract: The maintenance of a steady output voltage in the course of wide variation of input voltage of push-pull type regulator is achieved by sensing the output voltage, or current, in order to derive an error signal. The latter is then used for setting switching periods of transistors (34, 36) controlling the primary flux in the regulator transformer. The difference signal is obtained by comparing the ratio of the voltage-time curve during the conductive period of one transistor with the similar ratio of the preceding conductive period of the other transistor. The ON period of the transistor is then reduced, if its ratio is greater than that of the other transistor, or increased when it is smaller. Preferably amplitude variations are used for the transistor control.

Title: Marking strip for object detection monitored zone - has high permeability strip and narrower high coercivity strip
Inventor: TEITER WERNER
IPC: G06K19/06
Filed: 1979-08-07
Abstract: A marking element for detecting objects in a monitored zone is esp. for prevention of shop-lifting. An alternating magnetic field induces h.f. harmonic oscillations in the element which contains strips of high permeability and high coercivity materials. It is economical to make, contains little magnetic material, and is not easily deactivated. The high coercivity material strip is narrower than the high permeability strip by a factor between 0.1 and 0.75. The cross-section of the high coercivity material strip is chosen to ensure that its magnetic moment when magnetised by the field is not sufficient to saturate the strip of high permeability material. The element produces an identifiable signal when the high coercivity strip is magnetised. The total width of the strip is only a few millimetres.

Title: Fault monitor for NC machine tool data line - uses constant current transmission and voltage drop threshold detectors
Inventor: SCHILLINGER JAKOB DIPL ING
IPC: G01R19/165
Filed: 1979-10-06
Abstract: Data from a controller (2) are transmitted over a line (1) to an opto-coupler (3) forming the input to a numerically controlled machine tool (4). The 0 and 5V data levels from the controller are converted to 5 and 25mA by a constant current generator (6) which drives the line. The voltage drop across the line, due to its resistance (5) plus the opto-coupler, is monitored by two threshold detectors (7,8). One detector (7) gives an output (9) to the controller if the line voltage exceeds 2.5V e.g. if the line becomes open-circuit. The other (8) gives an output (10) if the line voltage falls below 0.5V, e.g. short-circuit. Line faults are thus immediately reported to the controller, which can take action to prevent damage or production of scrap. Series padding resistors (11,12,13) allow the same circuit to be used with lines of different resistance.
