Title: Pilot-controlled regulating device for AC amplifiers in communications systems
Inventor: HECHT GEORG ING GRAD
IPC: H04B3/10
Filed: 1981-03-18
Abstract: In a pilot-controlled regulating device for AC amplifiers in a communications system, transient processes occur in the mid-range amplification control state when the pilot or the operating voltage fails and the pilot receiver is removed if an integral regulator is provided and the voltage of the time-defining integration capacitor has a value which differs from the mid-range amplification control state when the pilot or operating voltage is restored or the pilot receiver is re-connected. If the voltage on the integration capacitor is set in such a way that it is equal to 0 for the mid-range amplification control state, each regulation procedure always begins with the mid-range amplification state following restoration. A resistor is disposed for this purpose in parallel with a series circuit of the integration capacitor and a resistor on the inverting input of the operational amplifier.
Patent DE-3116553-A1 (DE)
Title: Device for temperature regulation of insulating wires
Inventor: WUNDERLING KARL-HEINZ
IPC: H01B13/14
Filed: 1981-04-25
Abstract: Temperature regulation for wires which have subsequently been insulated by plastic material are known as a result of so-called conductor preheating apparatuses. In order to save these apparatuses and the energy required for operating them, reheating devices have been allocated to the upstream annealing paths. Since it is uneconomical to cool the wire after the annealing path in order to heat it again subsequently, hot-water cooling systems have already been used in order to use a portion of the heat from the annealing process as a result of a defined water temperature. This cooling operates with a large amount of inertia so that considerable quantities of waste can occur at the high flowrates. Temperatures above 100 DEG C cannot be achieved. The invention indicates the means for controlling the water column of the cooling path as a function of the initial temperature of the wire, so that a very large temperature range can be controlled very quickly.

Title: Apparatus for bending and hardening or just for hardening bar-shaped workpieces, in particular leaf springs
Inventor: POHL HANS CHRISTOPH DR ING DR
IPC: C21D9/02
Filed: 1981-07-14
Abstract: The invention relates to an apparatus for bending and hardening or just for hardening bar-shaped workpieces, in particular leaf springs. The apparatus has a plurality of tools, each comprising an upper part and a lower part, by means of which in each case the heated workpiece is gripped, in the process bent if required and, while still gripped, hardened in a treatment basin. Each closed tool is lowered from a dipping gantry by means of a dipping frame and, in the lowered position, released from the dipping frame and moved through the treatment basin on lower guide rails by means of supporting rollers before being captured by a lifting frame and raised by the latter in a lifting gantry into a position above the treatment basin, in which position the tool is opened and the workpiece removed and from which position the opened tool is transferred by means of its supporting rollers along upper guide rails to the dipping gantry. In order to shorten the cycle time and avoid intermediate tool positions, at least the upper cross-member of the dipping frame and at least the lower cross-member of the lifting frame are arranged outside the region of the dipping gantry and lifting gantry, respectively. Both frames have supporting pieces which project into the respective gantry and which engage the tools at a supporting surface offset from the supporting rollers in the vertical and/or horizontal direction. The end pieces of the upper guide rails, which end pieces project into the dipping gantry and into the lifting gantry, can furthermore be moved out of the gantry region.
