Title: Linearly or exponentially controllable amplifier circuit - with two amplifiers and eight bipolar transistors connected to form current mirror circuits
Inventor: BOEHME ROLF DR SC TECHN
IPC: H03G1/00
Filed: 1979-11-22
Abstract: The amplitude of a.c. signals in the low and medium frequency band is controlled linearly or exponentially to amplify variable input signals to a constant output signal with a large gain. Two (T1, T4) of four bipolar transistors (T1, T4) act as diodes with an earthed emitter and the base of (T1) is connected to that of (T2), and the basis of (T3) to that of (T4). A control voltage source (Qy) feeds the (T2, T3) emitters. The collector (T2) is joined to the emitter of (T5), to the input of a first amplifier (V1), and to the first input current source (Jx1). The collector of (T3) is similarly joined to (T6), a second amplifier (V2) and a second input current source (Jx2). The main current supply (JB) feeds the fases of (T5, T6) and the bipolar transistors (T7, T8); the main voltage supply feeds the transistors (T5, T6). This increases the useful frequency band and simplifies the circuitry. The negative feedback coupling remains unaffected by the set gain.

Title: Rapid temp. and pressure measurement - using conventional sensors and measurement intervals much shorter than sensor time constant
Inventor: GORILLE INGO DR ING
IPC: G01K7/42
Filed: 1980-04-26
Abstract: A method of measuring temp. is esp. applicable to measurement in the manifolds of internal combustion engines with turbocharging. It enables rapid measurement of temp. using conventional temp. sensors with long time constants. Two measurement values (V1,V2) separated by a small time interval (delta.t) are measured using the sensor. The internal (delta.t) is much smaller than the sensor time constant (T). The measurement temp. (v) is derived from a relationship involving the difference between the measured values (V1,V2) and the ratio between the time constant (T) and the time interval (delta.t). The relationship V equals (V2-V1).T/delta.t. is evaluated by a digital computer which raises the quotient to a power of two. Pressure in the manifold can be similarly measured using pressure sensors and a similar relationship evaluated by computer.

Title: Reclaiming solvent from adsorbent - esp. solvent removed from waste air leaving painting plant, where energy is also reclaimed
Inventor: BLAUDSZUN BERND DIPL ING
IPC: B01D53/04
Filed: 1980-11-07
Abstract: An adsorbant which contains a solvent is desorbed by a stream of hot inert gas. The gas is possibly pre-cooled, and is compressed. The gas is then used to drive an expansion turbine and is thus simultaneously cooled so the solvent vapours condense. The condensate is removed, whereas the inert gas is reheated and re-used in the desorption process. The pref. plant includes two adsorbers which are used alternately to collect solvent from waste air. While one adsorber purifies the air, a stream of hot inert gas is fed through the other and then through a network of heat exchangers and compressors and the turbine, so both the solvent and energy can be reclaimed. Used in reclaiming all types of solvents from air purificn. plant.
