Title: Controlled automatic lifting of telephone handset - using amplified ring tone signals as part of remote monitoring of rooms to operate trigger counter and solenoid
Inventor: KAETZLER GEB DUMANSKY BRIGITTE
IPC: H04M1/06
Filed: 1979-05-30
Abstract: Examples of the application of the remote monitoring system are rooms for the elderly or small children which are unattended, and checking for intruders. The system employs the conversion of acoustic signals into mechanical effort to raise the handset from its position when at rest. A microphone (1), sensitivity control (2), and amplifier (3) detect sound in the room being monitored. A filter (4) eliminates background noise and ensures that only signals associated with the ring tone are passed to a further amplifier (5) and integrator. The latter operates a trigger (6) and counter (7). After a preset count a power amplifier (9) is energised to feed the solenoid of an electromechanical device (10, 11) to lift the receiver or handset. A timer (8) can be incorporated in the circuit to hold the handset in the raised position for a predetermined interval.

Patent DE-3042848-A1 (DE)
Title: Five-limbed core frame for 3-phase transformer - has cross cooling channel between frames of main limb
Inventor: VALKOVIC ZVONIMIR DR ING
IPC: H01F27/245
Filed: 1980-11-13
Abstract: The five limbed core frame is constructed with three main limbs (I,II,III), consisting of coupled frames, joined in such a manner, that only the cooling channel between the first frame of the second limb (II) is bridged with the yoke (2), i.e. both frames (1) of the second limb (II) only, are connected together at the lower section. The magnetic coupling between the frames, only exists in the magnetic intersection of the main limb of the B-phase, while on the other hand, the frames of the main limbs (A,C) are not connected magnetically. This construction is based on the fact that the one single magnetic coupling in the limb of the B-phase, is sufficient for obtaining a satisfactory magnetic stray coupling in the core, so that, in such a core coupled in this way, an optimum is reached between local losses in the magnetic intersection, and the losses which are dependent on the magnetic coupling. This arrangement reduces magnetising current, heat losses, vibration, and other adverse effects.

Patent DE-3045106-A1 (DE)
Title: Temp. control of industrial esp. pusher-type ceramic furnace - uses variation in preheat of combustion air at constant flow rate
Inventor: MAIER PETER DR ING
IPC: F27B9/40
Filed: 1980-11-29
Abstract: If the temp. in the combustion zone falls below the set- point, the temp. of the combustion air is raised, instead of increasing the fuel supply and combustion air supply. Pref., the combustion air temperature in the recuperator and air preheater is increased and/or already preheated air or ambient air are supplied for regulating purposes. An additional air preheater is connected before or behind the recuperator for the furnace.Alternatively, the recuperator is in two parts, operating with different air temperature. Used in particular for industrial ceramic furnaces operating at 1200 deg.C and above. System avoids variation in heat transfer rates in the downstream zone of the furnace where in any case the temp. may be high enough; pressure fluctuations in the furnace; changes in the operation of the recuperator itself; and sluggishness in response of burners to the changes.
