Title: AGC using linear characteristic region of transistor - reduces distortion by using second transistor to control base current to gain control transistor
Inventor: HORNBURG KLAUS
IPC: H03G3/20
Filed: 1980-02-27
Abstract: The gain control has a control transistor (T1) grounding the inputs of a conventional amplifier (V). The transistor receives a very small base current in the region where gain control is not required. The transistor is connected at its base via a second transistor (T2), diode (D1) and capacitor (C3) to the output of the amplifier. The control transistor is shunted by a capacitor (C1) and forms a voltage divider with an input resistor (R1). The second transistor is connected via a resistor (R2) to a control voltage and acts as a current regulator. The distortion in the controlled ac output from the amplifier is very small as a result of the linearity of the characteristics on which the second transistor operates.

Title: Torque and thrust-transmission - for offset output shafts by ball and socket joints
IPC: F16D3/18
Filed: 1980-03-05
Abstract: A device to transmit a torque from an input shaft in stationary bearings through an intermediate shaft to an output shaft in an offset position which is additionally loaded by axial forces, e.g. the twin and multi-screw extruders of plastic tubes, profiles, sheets and granules, uses balls in the joints of all shafts. The shafts end in spherical cups which encompass the ball which has in each of two planes at right angles to each other a semicircular bulge to fit into a corresponding semicircular groove in each of the spherical cups. This enables the designer to keep the input shafts at a much greater centre distance than a given centre distance for multi-screw extruders. A simpler gearing and larger thrust bearings can thus be applied.

Title: Centrifugal pump for fire fighting - has priming pump automatically controlled according to both speed and discharge pressure
Inventor: GUETTLER ERNST DIPL ING
IPC: F04D15/02
Filed: 1980-05-23
Abstract: The fire fighting pump (1) and its priming pump (2) are driven by a common motor (4) through a gear box (3). A controller (5) operates a clutch (6) and a valve (7) to disengage the priming pump when the main pump discharge pressure (9) reaches a preset value. A tachometer (10) on the motor provides a signal which stops the controller from acting below a preset speed and prevents the priming pump being started below that speed. This prevents priming being stopped too soon. A switch (12) on the gear drive (3) provides a signal which activates a positioner (13) to increase the speed of the motor. This brings the pump into action quickly.

Title: Division of semiconductor rod into wafers - by forming standing wave along axis with ultrasound
Inventor: KELLER WOLFGANG-LUDWIG DR RER
IPC: C30B33/00
Filed: 1980-09-17
Abstract: Division of semiconductor rods into wafers involves subjecting the rod to ultrasound, at least at one end, so that a standing wave results along the axis of the rod. The frequency of the ultrasound generator used is adjusted so that the spacing of the vibration peaks of these waves corresponds to the desired thickness of the wafers. The rod is held at both ends and the holder on the end away from the generator acts as reflector. An ultrasonic generator can be placed at both ends. The holder consists of a material with small internal damping and high elastic modulus, pref. steel (in a half- tube) or ceramic. The rod is placed in a boat filled with liquid (water, an aq. soln. oil or etchant (KOH)). It is masked with a protective layer (of Ni or Ni-Cr alloy). The generator is adjusted to a frequency of 5-50 MHz and gives an energy of some 100W or some kW. The ultrasonic waves can be like an explosion or of gradually increasing amplitude and act on the rod for 1/2-1 min.. The process is specified for the division of Si monocrystal rods with the axis in the (III) direction into wafers with a thickness of 150-1500 (200-500) microns. Wastage is reduced considerably.

Title: Method of pushing a large-sized structure section by section through an earth body
IPC: E21D9/00
Filed: 1981-05-08
Abstract: So that large-sized structures, especially underpass structures extending lengthwise, can be pushed through an earth body, they are as a rule produced subdivided into sections and, with the inclusion of jack stations, are jacked one behind the other. In this arrangement, sections lying one behind the other had the same cross-section. In this mode of operation, high earth resistance had to be overcome in the final state and considerable deviations of the structure from the desired position could occur. By the use of sub-sections, of which in each case the front section in the driving direction has a slightly smaller outside diameter than the clear inside diameter of the rear section and is telescopically jacked from the rear section, the earth resistance is kept low and correction of the driving direction is possible from section to section.
