Title: Acoustic echo sounder for detecting objects - uses broad-banded frequency modulated signal from signal generator and aids blind people to identify objects
Inventor: BEUTER KARL DIPL PHYS DR
IPC: G01S15/10
Filed: 1979-07-13
Abstract: The echo sounder system can be represented by two main parts, the signal generator and the transmitter. The signal generator consists of an astable multivibrator or pulse generator, with variable pulse train frequency and pulse time. The output signal is filtered by a low pass filter in the pulse shaper and afterwards used as an amplitude modulation signal for an amplitude modulated sine wave generator. The square wave of the multivibrator is transformed into an exponential signal, and its slope changed and added to a D.C voltage. The resulting signal is used to control the instantaneous frequency of the sine wave generator. The desired frequency and amplitude modulated pulse shaped generator signal, with a particular pulse time and repetition rate, is amplified and fed to an electro acoustic transducer, which is a loudspeaker or hydrophone.

Title: Data circuit error and synchronisation failure detector - divides incoming signal by frame for comparison with locally-generated quasi-random sequence
Inventor: EICHLER PETER ING GRAD
IPC: H04L7/04
Filed: 1980-06-26
Abstract: A special bit sequence, pref. a quasirandom sequence, is sent by the transmitting terminal and generated also in the receiver for comparison with the incoming bit stream and synchronisation with it. The incoming data stream is divided into frames of a specific bit length and the number of errors in each frame detected and the number of consecutive errors are detected. Both are compared with the design criterion for the system to determine whether or not synchronisation has been lost. Measurements of other criteria such as noise and impulse noise are also considered and detected. The method complies with CCITT V52 where a 511 quasi random bit sample is used to determine the transmission quality of a link. Four frames of 128 bits each are used in the comparison method and theoretically the error count should be less than 34. If two frames exceed 34 and two frames are clearly less than 34 frame errors are detected but not a synchronisation error.
Patent DE-3023975-A1 (DE)
Title: Waffle baking dough application - using additional coarse and fine filter upstream of spray nozzles
Inventor: WAEHNER FRIEDEMANN
IPC: A21C5/00
Filed: 1980-06-26
Abstract: A system for the automatic application of free-running dough on baking moulds, esp. of liq. dough for waffle baking moulds, uses a pump to pass the dough through a filter from a mixer vessel to a metering pump. Downstream of the metering pump, the dough has to pass another coarse filter and a fine filter before it reaches the nozzles through which it is extruded on the baking mould. A pump takes the dough from a mixer to a buffer tank with a paddle mixer and through a filter to the metering pump. A second filter system consists of a coarse filter and a fine filter cartridge. The dough enters the cartridge radially and is extruded through nozzles in the pouring tube in the waffle baking mould. This eliminates the frequent clogging of the nozzles with their effect on downtimes in mass prodn. The dough remains homogeneous and without lumps, thus producing high-quality waffles.
