Patent DE-19714679-A1 (DE)
Title: Air conditioning system with regulated coupling of solar collectors and heat pumps
IPC: F24J2/00
Filed: 1997-04-01
Abstract: The system has an earth collector and a solar collector for extracting heat energy. A heat pump extracts energy from the earth with the earth collector or from a buffer store (1). The buffer store primary side output (2) is connected to the input (1) of a collector field whose output is connected to the buffer store primary side input (4). The secondary side heat pump output (9) is connected to the heat pump store primary side input (11) and the heat pump secondary side input (10) is connected to the heat pump store primary side output (12). The heating circuit is selectively heated from the heat pump secondary side via a heat exchanger (19) and three-way valve (20). The liquid in the heating circuit can be cooled by the heat exchanger by switching over the heat pump. The heat extracted from the room is passed to the reservoir or earth. Three-way valves (21,22) change over between the earth collector and reservoir.

Title: Method to determine target parameter, e.g. total mass flow of two-phase fluid in pipe
Inventor: ECK MARKUS
IPC: G01F1/36
Filed: 1997-06-07
Abstract: The method involves measuring the pressure of a multi-phase flow as the primary parameter. The variation in time of the primary parameter is measured and compared with reference variations. The measurement value of the target parameter is calculated as a function of the results of the comparison. The primary parameter may be a static pressure, an impact pressure, or dynamic pressure. The pressure may be measured at a point which is always in contact with the same phase of the fluid. The target parameter may be the total mass flow, used to regulate the fluid flow in a pipe.

Patent DE-19804891-A1 (DE)
Title: Circuit for vehicle display lighting
Inventor: KEINATH JENS
IPC: B60Q3/04
Filed: 1998-02-07
Abstract: The circuit has a bipolar transistor (5) for current flow through a number of LEDs (1-4), which are directly connected to the vehicle board net. The transistor characteristics and cooling continuously compensate for power surges of the onboard supply's effect on the brightness of the LEDs. The flow of current through the LED is regulated so that the forward current remains constant. The emitter feeds the collector emitter current through a resistor (6) to earth or to the negative potential of the supply voltage. The lighting is then regulated via the base by a potentiometer (7) or digital control circuit providing a pulse width modulated signal to the transistor base. The potentiometer is adjusted by the vehicle driver. Voltage fluctuations appear across the collector emitter of the transistor (5), the transistor can quickly compensate to intercept fluctuations of up to 150 V without change in the LED brightness.
