Title: Integrated circuit for driving MOS gated power semiconductor devices
Inventor: WOOD PETER N
IPC: H03K17/0812
Filed: 1996-09-27
Abstract: In a circuit for driving MOS gated power semiconductor devices (10, 11 Fig 1) connected in a half bridge circuit for supplying an output signal to a load circuit, such as a discharge lamp (60, Figs 5 and 6), a latch circuit 104 is coupled to a timer circuit 101-103 for controlling the frequency at which the MOS gated devices are switched, high and low side dead time delay circuits 107, 108 are each coupled to the latch circuit 104 for delaying an output signal from the latch circuit so as to prevent simultaneous conduction of the MOS gated devices (10, 11), high and low side driver circuits 116, 110 are coupled to the high and low side dead time circuits 107, 108 and provide high and low side outputs for turning on and off the MOS gated devices (10, 11), and dead band control circuit (R IN ,Rf and 21, Fig 3) provides a dead time control signal to the high and low side dead time delay circuits in response to a feedback signal from the load circuit. A further aspect relates to a circuit for driving a load comprising a self oscillating driver circuit and a time delay circuit for preventing simultaneous driving of first and second MOS gated power semiconductor devices. A dimming function is obtained by controlling the feedback voltage by means of a resistor (70, Fig 6).

Patent DE-19647186-A1 (DE)
Title: Colour mixing for in-line application
IPC: G05D11/02
Filed: 1996-11-15
Abstract: Production of a specific colour involves mixing three primary colours, i.e. red, blue and yellow.  Each colour is drawn from a storage tank into one of three intermediate storage tanks in proportions and volumes determined by a computer, in accordance with a colour recipe and the predicted requirements of a particular application.  Water and other auxiliary liquids are then added so that the volume in all three intermediate tanks is the same.  The tanks feed colours at equal rates into a mixer, which then delivers the required blend to the point of application.

Title: Information display for time differentiated system of telephone charges
Inventor: KOEHLER THOMAS DIPL PHYS
IPC: H04M15/28
Filed: 1997-01-31
Abstract: The memory module provides information about the telephone charges to the display from an electronic data memory for specified required information. An electronic control links, during a time repeatable selection, the actual time signal with at least one non-validity or validity criterion of a time-limited charge. Accordingly, a selection is made from telephone charge information of the memory group dependent on a presettable selection scheme. Information about the charge height is selected for at least one charge valid at the actual time, and for at least one not yet valid, but validated in the next charge change. The control regulates an electronic display to show the charge selected for the actual time.
