Patent DE-2646324-A1 (DE)
Title: Revolution speed controller esp. for IC engine - has input from inductive speed pick=up transferred to operational amplifier connected as integrator
Inventor: HORBELT MICHAEL ING GRAD
IPC: G01P1/10
Filed: 1976-10-14
Abstract: The revolution counter and controller, esp. for a rotary member of an IC engine, comprises a speed pick-up (1) (typically on inductance coil), a pulse former (2) and a transistor switch (3). The output from the collector terminal of the transistor leads to the inverting input of an operational amplifier (8) through a coupling resistor (7). The positive input of the operational amplifier is held at a fixed potential by a voltage divider which is formed by two resistors (12, 13). The output of the operational amplifier is carried through another coupling resistor (14) to an output transistor (15). In the input stage, the collector load resistor (4) is in series with an adjustable thermo resistor (20), which provides temperature compensation.

Inventor: RICHTER SIEGFRIED DR
IPC: B41N1/08
Filed: 1976-10-15
Abstract: The process for producing offset printing plates comprises rendering a roughened carrier hydrophilic, activating and catalysing the carrier on the printing side, one-sided coating of the carrier with a metal layer by means of a currentless reductive deposition process, treatment of the metal layer with a chromatisation solution and finally fixing of the metal layer by heat treatment. The process permits secure anchoring of the metal layer on the carrier, in particular a plastic carrier, and good adhesion of the photolayer to the metal layer.

Title: Felt tip pen mounting - is integral with body and has spring clamping members moving freely in radial direction
Inventor: ELSNER HORST
IPC: B43K8/02
Filed: 1976-10-22
Abstract: The pen or pencil tip mounting is partic. for felt-tipped pens, and is integral with the pen body or tip, being equipped with spring clamping members moving freely in the radial direction. It can comprise a clamping ring (3) slit for its whole length, and joined by one or more ribs to the body (1') or tip, or integral with it.

Title: Flue gas purification - by filtering through metal cloth combining dust removal with catalytic conversion of toxic components
Inventor: HOELTER HEINZ
IPC: B01D53/34

Title: Hydrodynamic torque converter for pump and turbine - has pivoted blades for pump of flexible type to reduce hydraulic losses during coupling of torque
Inventor: FLOEGEL EBERHARD
IPC: F16H61/56
Filed: 1978-01-26
Abstract: The hydrodynamic torque converter comprises pivoting blades (9) made of plastic material. The blades pivot around an axis (11) to be moved by the liquid current, to take the same direction as the current. Each of the pivoting blades is placed between two adjacent fixed blades so that its pivoting angle is limited by both directions of these two fixed blades (10). In each fixed blade is fitted a locking peg which may engage with a corrsp. cut-out in the moving blade, in order to locate the mutual orientation of the two blades. Each pivoting blade is made of a single piece of spring steel and is anchored at one end in a profiled member. The pivoting blade is for a flexible coupling between a pump and a turbine which have collinear but separate driving spindles connected to the housings for each component. The pivoted blades accommodate themselves to torque changes applied by the pump. Losses of hydraulic energy are reduced by the flexible blades.
