Title: Receiver for signals with residual carrier - carrier filtered out by narrow band-pass filter from two sidebands
Inventor: TAUSCHECK EBERHARD DIPL ING
IPC: H03J3/14
Filed: 1973-11-23
Abstract: The filtered out carrier is used for automatic frequency control. A phase bridge first input is connected to the filter through an oscillating element whose equivalent circuit consists of a damped series oscillating circuit in parallel with a capacitor, so that two resonant frequencies exist, between which the impedance is inductive, and outside which it is capacitive. A second input of the phase bridge is connected to the filter through a resistor. When the oscillating element phase shift is positive or negative, the phase bridge delivers a signal at its first or second output respectively. A signal responsive optical display device is connected to one of the phase bridge outputs through a monostable flip-flop.

Title: Remote operated wing mirror - with second hand lever to dip mirror when dazzled without losing mirror setting
Inventor: KIELMANN ERICH ING GRAD
IPC: B60R1/08
Filed: 1974-04-23

Title: Screw conveyor for sticky granulated materials or sludge type mixtures - two parallel helical conveyor shafts used for axial transport with pins for blade cleaning
IPC: B65G65/46
Filed: 1974-06-18
Abstract: A screw type conveyor system employs two counter rotating screw type shaft for the transport of granulated materials with a tendency to clog or various types of sludge. The main shafts (2, 3) are tubular in cross-section and are parallel to each other and a thin helical profiled section (5) along the length. Rotation of the two shafts at the same speed, but in opposite directions results in an axial transport of material from the container in which the system is located. The conveyor may be moved in a direction at right angles to the axis of the shafts. With materials that exhibit a tendency to build-up on the helix a number of pins (8) are located equidistant radially on one of the conveyor shafts in order to clear the blades of the other shaft.

Title: Induction furnace crucible fullness and erosion monitor - uses relationship between voltage and current in induction coils
Inventor: KOEHLER HENNING DIPL ING
IPC: G01F23/26
Filed: 1974-10-24
Abstract: The amount of material in the crucible, and an indication of the erosion are displayed on a panel using lights. Basically, both parameters are inferred from the relationships between the voltage supplied to the various induction coils and the current flowing through them. There are three coils wound round the crucible at various points, supplied by mains transformer windings. A current detection produces a tunable output voltage via a suitable transducer proportional to the supply current, and this is compared with each coil voltage in two different tunable ratios, to give three outputs monitoring the content level in the crucible, and three outputs monitoring erosion state. These outputs are binary in nature and light lamps when given thresholds are exceeded.
