Title: Compensating for multiple shaft angular velocity inequality - by using electronic pulse detectors passing torque signals to control unit producing difference signal
Inventor: QUIRUS THOMAS ING GRAD
IPC: B63H23/28
Filed: 1979-01-29
Abstract: A method of measuring and compensating revolution rate and angular position differences of two or more shafts is esp. for propeller drive shaft control of multiple screw ships. It enables regulation shaft revolution rates to the same value and compensation of mechanical oscillations simply and reliably. Electronic pulse detectors prod. measurement values which are fed to an electronic measurement and control device. The difference signal derived from the detector outputs is used to adjust the torque applied to the shafts for a given drive system power output by varying the propeller blade incidence angle. The torque may alternatively be controlled by varying the power supply generator power, the load of an electrical drive motor, the slip of an electrical slip coupling, or the effectiveness of an eddy current brake where fixed propellers are employed.

Title: Pressure exchanger driving IC engine supercharger - uses fluidic flip=flop admitting exhaust gas to compress air in tuned pipe
Inventor: WYDRA KARL
IPC: F04F99/00
Filed: 1979-05-11
Abstract: The supercharger has few moving parts. A fluidic flip-flop valve (1) admits a certain amount of exhaust gas alternately to one of two compression tubes (4, 5). The high pressure exhaust gas compresses the air in the tube and discharges it through a non-return valve (6, 7) into the air inlet manifold (10) of the engine. The suction created behind the volume of high pressure gas admitted to the compression tube (4, 5) opens a second non-return valve (11, 12) to admit air for compression in the next cycle. The compression tubes are interconnected by control lines (17, 18) which, when pressure rises in the compression tube (5), opens a discharge valve (13) in the other tube (4), now at the end of compression, to discharge the exhaust gas into the silencer. The exhaust valve (14) in the tube (5) is operated in the same manner by the other line (18).

Title: Particle size monitor using electrostatic noise - removes and separates samples also recombines fractions before returning to gas stream
Inventor: SVAROVSKY LADISLAV
IPC: G01N27/60
Filed: 1979-08-14
Abstract: The method and apparatus utilise the principle of differential flow classification in which the gas stream or a portion is passed through a separator whose separation efficiency is size dependent. The electrostatic noise of a particular fraction is related to the mass flow rate of the solids in that fraction, and is unlike the DC component, little affected by leaks or probe surface condition. The apparatus takes off a sample from the gas stream and feeds it to the separator. The apparatus also feeds the fractions back to the gas stream after the electrostatic noises have been compared. The two fractions are recombined before they are fed back to the gas stream.

Patent DE-2939255-A1 (DE)
Title: Pacemaker with high resistance batteries - uses low resistance load which is compensated by switches controlled by comparator
Inventor: EKWALL CHRISTER
IPC: A61N1/362
Filed: 1979-09-27
Abstract: Pacemakers have low resistance circuits in order to match the low resistance load formed by the heart. However modern pacemakers use lythium batteries which have a high internal resistance and should therefore operate with a high load resistance in order to avoid instability. The problem is solved by feeding the battery voltage to one input of a comparator and the voltage across a reservoir capacitor to the other. The output of the comparator controls a circuit which maintains a constant voltage level at the capacitor. A comparator (10) with high input resistance samples the battery voltage (Ur) and the voltage (Uc) of the capacitor (4) whose discharge through the heart (1) produces the stimulating pulse. The output of the comparator controls switches (8,9) which will tend to counteract the fluctuations of the voltage levels of the capacitor.

Patent DE-2947950-A1 (DE)
Title: Hair drying suction fan - has brush for air suction through bristles and hair, and uses only small proportion of hot air
Inventor: GRUBMUELLER HANSGEORG
IPC: A45D20/50
Filed: 1979-11-28
Abstract: The fan dries hair mainly by suction of air through the wet hair, with only partial application of small volume of hot air to the drying process. The hot air is directed so that it does not reach the skin and thus does not dry it excessively. It contains a brush, connected to two blowers, which increases the suction effect through its bristles and provides an air discharge 1 mm above the bristle tips. In this manner the hair roots and skin are free of excessive, damaging heat, while the time required for drying may be reduced by greater volumes of applicable hair. Such a hair drier also facilitates the hair shaping and conditioning.

Title: Diversity reception system for opposing fading - uses ring counter and comparator in logic system to control sequential aerial switching
Inventor: SARTASOV NIKOLAJ A
IPC: H04B7/08
Filed: 1980-02-25
Abstract: The diversity reception system for opposing fading uses a set of aerials connected to a switching system with a set of inputs corresponding to the number aerials connected to a multi-stable circuit which receives control pulses to operate a changeover from one aerial connection to another. This multi-stable device can be a ring counter, and the next aerial in the set is selected in turn, then the first aerial is again connected. The output of the receiver is connected with a stage which monitors the quality of the received signal. The voltage level of the intermediate frequency can be used as the reference value, also the signal to noise ratio or distortion can be used. An operational amplifier can be used as a comparator. A control unit connected to the ring counter receives pulses from a pulse generator and signals from the comparator. A memory supplies signals to the comparator and the whole forms a logical control system for the control unit.
