Patent DE-2831336-A1 (DE)
Inventor: KAMBER FREDY
IPC: H05B41/392
Filed: 1978-07-17
Abstract: This method is used for the light brightness control of a gas discharge lamp (L) by means of phase-gating control (PS) for the supply alternating voltage. Ignition of the discharge path is performed with the aid of a capacitive auxiliary electrode (Eh) which is at least approximately at the potential of one lamp electrode. In order to reduce the mains flicker at low brightnesses by a simple type of connection of the auxiliary electrode, the ignition is initiated in those half waves of the supply alternating voltage (Un) which correspond to a negative potential of the lamp electrode (Eo), which is at the same potential as the auxiliary electrode, with respect to the lamp electrode (E1) whose potential differs from the auxiliary electrode. In this case, the initiation is performed at a phase angle which is earlier with reference to the other half waves. <IMAGE>

Title: Circuit breaker with overcurrent trip test switch - has additional connections to permit use as remote trip
Inventor: BOEKER GUENTER ING GRAD
IPC: H02H3/33
Filed: 1979-03-14
Abstract: The circuit breaker has an overcurrent trip, and an overcurrent trip test circuit. It may be opened from a remote point without the necessity of a separate trip coil. The contacts (12a, 12b) of the trip test switch (12) are brought out to additional terminals (12', 12"). This allows them to be connected (15) to a remote control centre in which there is a switch (16) for bridging the contacts. The trip test is typically connected between one phase and neutral, with a limiting resistor in series in order to produce a simulated overload current. A further advantage is that the circuit breaker cannot be reclosed until the overload trip has been reset. It can thus also be used as a lock out to prevent unauthorized reclosure.

Title: Calling tone monitoring and recognition circuit - converts sinusoidal signal into square wave and measures time between edges
Inventor: HARTL ALBERT DIPL ING
IPC: H04M7/00
Filed: 1979-09-26
Abstract: The circuit eliminates incorrect response to the telephone equipment to spurious impulses or signals on the incoming line. The normal sinusoidal calling tone is converted into a square wave and passed to a unit (IFS) producing an impulse for each edge of this wave. A filter eliminates impulses due to noise (StIU), and the clean signal passes to a time measuring circuit (Z) which is set and reset (ZRS). The timer (Z) responds only if the interval between pulses is initially longer than a set minimum value, this value reducing after initial recognition. The timer operates in conjunction with a frequency evaluator (FA) to determine if a genuine calling tone is being received. Only when this condition has been established is an output signal given to allow the call to proceed.
Patent DE-2940439-A1 (DE)
Title: Transformation system for colour coordinate system - transforms digital chroma signal from rectangular coordinates into digital colour signal and saturation signal in polar coordinates
Inventor: KUHN FRANZ DR
IPC: G03F3/08
Filed: 1979-10-05
Abstract: The polar colour coordinate system is divided into quadrants, each identified by a number. The higher bits in the chrominance signal are evaluated first to determine the relevant quadrant. The equations for transforming the chrominance signal into colour signal and saturation signal for this quadrant are stored in a table memory. The colour signals for all quadrants are obtained from the quadrant number and the stored values. The amount of storage space required is reduced by subjecting the signals to a shift in position before addressing the table memory. This shift is reversed when the values are read from the table memory.. The system is fast, cheap and reliable.
