Patent DE-4041858-A1 (DE)
Inventor: FLEISCHER RUEDIGER
IPC: H04R9/02
Filed: 1990-12-24
Abstract: According to the invention, a drive system designed with extended travel for bass loudspeakers (10) is specified which prevents the voice coil (21) from impinging on the magnet bottom pot and the voice coil (21) from coming to rest on the top pole plate (12) even if the mounting elements are designed to be very soft. For this purpose, a further coil arrangement (22), to which the amplifier power is also applied, is arranged on the voice coil former (19). Since the current is designed to flow in the opposite direction in coil (21) and coil arrangement (22), the voice coil former (19) is actively decelerated as soon as one of the two winding areas (23; 24) plunges into the air gap (25). <IMAGE>

Title: Gas turbine engine operating method - has atomiser nozzle to inject water, so that evaporation enthalpy corresponds to output of adiabatic compression
Inventor: POHL HANS CHRISTOPH DR ING
IPC: F02C7/143
Filed: 1991-05-06
Abstract: The method consists of the stages combustion air compression; combustion of a gaseous or liquid fuel; and subsequent expansion in the turbine. To approximate the compression process to a quasi isothermal process, liquid water is injected through atomizer nozzles into the air flow passing through the compressor. The water is at a suitable pressure (5-20 bar above the compressed perssure), dependent upon desired temperature distribution, distributed over the individual compression stages. The water supply for each stage results from the desired end temperature of a stage, but there is a limit for complete water volume of 0-approx. 0.2 kg water/air. This results from the fact, that the water flow per compression stage, and the lowest achievable compression temperature, are balanced to heat- and material transfer ratios.
Patent DE-4116939-A1 (DE)
Inventor: BEISEL WERNER DIPL ING
IPC: H04Q11/04
Filed: 1991-05-24
Abstract: In a data transmission system, a switching network in a connection node (VK) includes switch groups (SCH) for switching channels, which are each assigned to one or more time slots within the framework of a multiplex time signal, e.g. virtual containers of a STM-1 frame according to CCITT recommendations G707 to G.709. Each switch group (SCH) is modular and linked to one another, and contains a memory (DS) with several independently readable memory outputs (SA1 to SA4), through which the storage area can be accessed. Each part signal of a respective memory address can be connected with a data output of the switch group (SCH) through selectors (SEL1 to SEL4). A connecting memory (VB1 to VB4) controls the reading of each part signal from the memory (DS) to a memory output (SA1 to SA4) and a selector (SEL1 to SEL4). A coupling field may be composed of switch groups (SCH) arranged in columns and lines, as required. Each data outputs (DA1 to DA4) of one switch group (SCH MN) is connected to a connection input (VE1 to VE4) of the following switch group.
Patent DE-4118718-A1 (DE)
Inventor: HEMMINGER HERMANN DIPL ING
IPC: G01R35/02
Filed: 1991-06-07
Abstract: The invention relates to a circuit for testing the functional condition or status of a sensor. The sensor may either be operational or emit a fault signal, principally caused by a short circuit to earth, a short circuit to the power supply voltage or a break. Automatic status detection is important for such sensors which can be observed and monitored only at long intervals or which apply their signals to fully automatically operating devices. In such cases it is customary to monitor operating parameters continuously and emit binary status signals. In checking the operation of a sensor it is desirable to be able to discover different operational conditions in the simplest possible way. The problem thus arose of providing a test circuit for a sensor which makes it possible to differentiate between various operational conditions in a simple manner.

Title: Semiconductor relay with optical coupler for sepg. input and load circuit - and prodn. in small area of semiconductor chip with slightly doped n=islets
Inventor: ROST WOLFGANG DIPL ING
IPC: H01L21/762
Filed: 1992-02-29
Abstract: Semiconductor relay (SCR) with optical coupler for galvanic sepn. of the input and load circuit consists of a light emitter in the input circuit, a row of dielectrically insulated photodiodes, optically coupled with this, a load swtich with control FET controllled by this and a switch parallel to the control zone of row of photodiodes. The switch is controlled directly by tappings (12; 16; 17) of the rows (10) of the photodiodes, which generate the control signal for the load switch (18). These tappings pref. are sited so that the magnitude of the control voltage generated between them directly exceeds the thresehold voltage of the switch (15) and none of the control electrodes of the switch is directly connected with the outer terminals (11) of the row of photodiodes. The switch (5) pref. consists of 2 complementary, intrinsically conducting FETs (13,14) with interconnected source electrodes, with the drain connected to one terminal of the control zone of the load switch and an outer terminal of the row of photodiodes. The gate and source electrodes are connected to the tappings so that light emission causes switching in one direction, which is reversed when light emission stops. One of the FETs may be replaced by a resistor and the diodes parallel to this pref. have larger radiation-sensitive area for compensating the load. Apart from the diodes, the relay is protected from radiation by the light emitter in the input circuit by an opaque coating or opaque structurised metal wiring trace. ADVANTAGE - Fast switching times and direct control are obtd., serial voltage drop is avoided and the chip area needed is small.
