Title: Coding of binary values - uses soft phase keying of carrier and starts with two rectangular oscillations from which two other signals are derived
Inventor: ROBRA JOERG DR
IPC: H04L27/20
Filed: 1978-08-02
Abstract: The coding starts from two rectangular oscillations. The frequency of the first is an n-th multiple of the carrier frequency, and that of the second and n-th multiple of half the transmission speed. Two further rectangular signals are derived by frequency addition and subtraction of the above primary rectangular oscillations. The two rectangular signals are applied to a frequency divider each, with a division ration n. They are then linearly superposed and applied to a low-pass filter. Pulses of the second primary rectangular oscillation are suppressed for coding of the binary "O".

Title: Measured value curves representation on CRT screen - by subtracting measured value proportional prior curved value from processed curve values for comparator
Inventor: HORNUNG MANFRED ING GRAD
IPC: G01R13/40
Filed: 1978-12-27
Abstract: The measured values are presented on a c.r.t. operating in a line raster mode. A receiver containing a comparator stage is supplied with a line position proportional signal and the image point position proportional signal within the line. The coincidence signal of the comparator triggers the brightness scan of the image point on the c.r.t. screen, the space between the measured values being bridged by brightness scanned image points. The next previous measured value proportional curve value is subtracted from the curve value addresses and curve values. The obtained difference is supplied to the comparator which transmits brightness scanned signals only, when the differences have the same polarity sign and when the difference of the curved values is of greater magnitude. Two differential stages are connected to the comparator. The logic signals are supplied to a triggering input of the comparator via an XOR-gate.

Title: Detoxification, esp. denitrification of combustion waste gas - using oxygen and steam to convert nitric oxide to nitrogen di:oxide, then nitric acid
Inventor: HEIN SIGRUN
IPC: B01D53/56
Filed: 1980-03-18
Abstract: Detoxification, esp. denitrification of waste gases from combustion plants is carried out by oxidising the NO to NO2, using the residual O2 content of the gas and the steam present in it as prim. energy carrier, and chemical reaction of the NO2 in water to a HNO3 + H2O mixt. NO and NO2 can be largely eliminated safely and economically from waste gases from plants, e.g. boilers with burners, engines and turbines using cheap additives. The gases are cooled below 100 deg.C (60 deg.C) in waste gas boiler(s) and the condensate is collected and re-used. The residual gases are passed through a by-pass pipe, mixing vessel, chamber or tube, fluidised chamber and/or gas scrubber, into which air, O3 and/or O2 is passed and in which catalysts are provided for the oxidn. of NO to NO2 or the decompsn. of 2NO to N2 and O2 and/or there is an electric charge carrier (e.g. from a high voltage field).

Title: Sliding piston with sealing rings - has drillings from grooves to interior to reduce ring pressure friction in cylinder
Inventor: BAYER WILLY
IPC: F16J9/08
Filed: 1980-04-17
Abstract: The piston is for use in an engine having rings forming seals in grooves. Drillings lead from the ring grooves to the interior of the piston, to prevent pressure building up inside them. The dimensions and number of the drillings can be such that the flow through the ring gap is greater than the outflow through the drillings. The design reduces the friction of the rings against the cylinder walls.
