Title: Method for demodulating FSK data trains - using count output comparators for precisely detecting logic level changes
Inventor: DOSTER RAINER DIPL ING
IPC: D04B15/78
Filed: 1979-07-18
Abstract: The demodulator employs at least two high frequency counters which count the periods of positive half wave cycles contained in the message train. The method requires that at least two consecutive half waves are thus measured and retained in memory (2) in order to derive therefrom whether there takes place a transition from a lower frequency to a higher, or vice versa, or no change at all. It is the trend detector (2) which determines the clock rate inputted to an up/down counter (4). The counter counts up when there is a transition from a higher to a lower frequency (longer half wave period) and vice versa. The unit also comprises another counter whose digital count output is static and corresponds to the arithmetic mean half wave period corresp. to the mean of the two frequencies employed. By comparing the instant count of the trend counter with the digital status of the mean half period counter, it is possible to define very accurately the transition from one logic level to the other.

Title: Contact thermometer two-step regulator fail=safe circuit - switches irreversibly non-critical for excessive transfer resistance
Inventor: GERSTEL EBERHARD
IPC: G05D23/275
Filed: 1979-12-04
Abstract: A fail-safe circuit for a two-point controller contg. a contact thermometer with two contacts connectable via a mercury column can be switched between a critical and a non-critical state. It also contains electronic circuits and switches irreversibly to the non-critical state when the transfer resistance between the adjustable thermometer contact and its contact piece reaches an excessively high value. An amplifier circuit (16) produces a voltage (U1) inversely proportional to the total impedance of the connector leads and the thermometer. The amplifier (48) output drives three comparator circuits (62,64,66) with different reference voltages (U1,U2,U3). A first controlled circuit (76) switches critical when the amplifier output lies between the two lower voltages (U1,U2) and non- critical when it is greater than the middle voltage (Uz). A second circuit (78) switches the first (76) irreversibly non-critical if the output (U4) is less than the lowest voltage (U1) or between the middle and highest (U2,U3).

Patent DE-3007909-A1 (DE)
Title: Discontinuous waste heat boiler - esp. suitable for reclaiming heat in waste gases leaving steel-making converters
Inventor: WEBER WILHELM ING GRAD
IPC: F22B1/18
Filed: 1980-03-01
Abstract: Hot waste gases leaving a plant, such as a steel making converter using oxygen for the refining of molten iron, travel through chimneys. The chimney walls are used to heat boiler feed water, which flows through a boiler, and is then recirculated through the chimney walls via pumps. During an operating pause, when no heat is being generated by the plant, a third pump is used for reduced circulation of the boiler feed water through the chimney walls, and is connected to the latter via a pipe and valves. During steel mfr. in a converter, a boiler is used to reclaim waste heat in the exhaust gas leaving the converter. When no steel is being made, only one pump using a relatively small amt. of energy is used to keep the boiler warm, so excessive thermal stresses are avoided when the converter gases are next used for steam generation.
