Patent DE-4101649-A1 (DE)
Title: Flow sensor with two electrical connections - has heat source or sink and temp. sensor and changes internal resistance depending on flow exceeding or falling below threshold
IPC: G01P5/10
Filed: 1991-01-22
Abstract: The flow sensor (1) has at least one heat source or sink, at least one temperature sensor for detecting the temperature in the source or sink or its immediate surroundings, and an electronic circuit for evaluating the temp. signal. The heat source or sink and the temp. sensor can be combined into a single component which can act simultaneously or sequentially as the source or sink and temperature sensor. The sensor has only two electrical connections and two completely different values of its internal resistance, which it adopts when the flow exceeds or falls below a defined value, can be evaluated as its output signal. USE/ADVANTAGE - For e.g. for monitoring lubricant or coolant flow, measuring flow of surround flowing medium. Sensor has only two electrical connections and hence reduces cabling and connector costs.
Patent DE-4103408-A1 (DE)
Inventor: BEYER LUTZ
IPC: B28B13/02
Filed: 1991-02-05
Abstract: The invention concerns a device for the production of accurately dimensioned mouldings, e.g. oxide magnets, from moulding paste by wet-pressing. The invention also concerns a process for the production of such mouldings, and the mouldings themselves. The moulding paste is fed into the moudling die (6) by a pump (1), the die containing a punch (7) capable of exerting a pressure on the paste. The measurement and control electronics proposed by the invention includes a sensor element (8) which detects relative motion between the punch (7) and the die (6), plus control electronics which determine, from the measured data, the punch-travel distance and controls the pump feed pressure if punch travel lies outside a given range.

Title: Transistor-switched DC to DC transformer-based converter - utilises length of coaxial cable to absorb back emf frm transformer primary winding
Inventor: RUETT-HUEBNER WINFRIED
IPC: H03K17/08
Filed: 1991-02-11
Abstract: The transformer comprises a transistor (T), an open-ended length of coaxial cable (L) and a transformer (Tr), the primary winding (P) of which is connected in series with the transistor. The central core of the coaxial cable is connected to a transformer winding towards the transistor (collector) end of the primary winding, while the coaxial cable screen is connected to the transistor emitter. The base of the transistor is driven by a square wave signal that turns the transistor on and off, chopping the primary current (I) and inducing a voltage (and corresponding current) in the secondary winding (S). The length of coaxial cable acts to absorb the back emf of the primary winding that results when the transistor is turned off, reducing the voltage (U) across the transistor for a length of time proportional to the length of cable. When the transistor is turned on again, a slightly increased current will flow through the transistor initially as the charge stored along the cable flows back through the transistor. ADVANTAGE - Potentially damaging transformer back emf absorbed without incurring overheating or wasting energy.

Title: Electrical installation generating power in isolated region - includes solar collector equipment with heat pump powered with travelling wave generator from wind power converter
Inventor: KIRCHMAYER LEONHARD
IPC: F03D80/70
Filed: 1991-07-03
Abstract: The wind power converter (1) with a rotor (2) supported on a column (3) is designed as a travelling wave generator. The rotation axis is pref. vertical. Solar energy collector equipment (5) supported on a mast (4) is added. It includes four to five collector elements (6) designed as hybrid collectors, a first set of ducts for the primary heat agent and a second set of ducts in contact with the surrounding atmosphere. Each set of ducts is connected to a reservoir; some to a high temp. reservoir and others to a low temp. reservoir. In the junction between the reservoirs a heat pump is operated with the generator.
