Patent DE-3323544-A1 (DE)
Title: Impedance circuit with electrically controllable impedance and selectable control characteristic
Inventor: RALL BERNHARD DIPL ING
IPC: H03H11/48
Filed: 1983-06-30
Abstract: For an impedance circuit with electrically controllable impedance and selectable control characteristic which uses an operational transconductance amplifier it is proposed to connect the inputs of the amplifier via one resistor each to an earth line carrying the reference potential, to provide feedback by means of a third resistor from the output to the inverting input of the amplifier and to use the output of the amplifier and the earth line as input terminals for the impedance circuit. The control input of the amplifier which controls the slope is connected to a first current balancing circuit with selectable current balancing ratio and two current outputs which lead to a second current balancing circuit. The current of one current output can be controlled by means of the second current balancing circuit and the current of the other current output influences the current of the one current output in the sense of positive feedback. The input impedance can be controlled in steps via the second current balancing circuit if it is constructed as an A/D converter. Using a constant current which only depends on the absolute temperature in addition to a feedback current, a temperature-independent linear resistance variation as a function of the control variable is achieved.

IPC: B21B39/16
Filed: 1983-07-16
Abstract: In a cold strip rolling chain for selectively feeding the rolled strip continuously from a strip accumulator and discontinuously from a strip reel, it is difficult to decide which of the two operating modes should be given priority as regards the design and arrangement of the auxiliary equipment for feeding the rolled strip. The intention is to improve a cold strip chain of this kind in such a way that equally favourable conditions are achieved for the continuous rolling mode as for the discontinuous rolling mode. For this purpose, a guiding apparatus, which is arranged ahead of the coil preparation device and guides the strip coming from the strip accumulator into the coil preparation device, is provided.

Title: Domestic corn mill
Inventor: VOGLER HARTMUT
IPC: A47J42/16
Filed: 1984-08-07
Abstract: In order that different grain can be stored and, if appropriate, mixed in a mill, in particular a domestic corn mill, a mill consists of four partitions and corresponding inner and outer walls which form a supply compartment having four chambers for the grain and enclose a motor and control compartment. In a support plate, four valves, which can each be opened individually, with their piping system are assigned to the chambers in order to feed the grain to the mill stones. An upper stationary stone and a runner, which forms the centre of the stone conically with part of its basic surface, receive the grain via spoon-shaped screens. Opposite the grinding sides, each millstone is enclosed in a die-cast plate. Steel bars anchored in the stationary stone guide the electric motor, via spring-mounted support plates, and the crusher stone, connected to the motor spindle, to a horizontally parallel spacing of the two grinding surfaces. The vertical spacing of the grinding surfaces can be adjusted via a flanged-on lifting/lowering spindle. The vibrations occurring during a grinding process are absorbed via a system of Silentbloc-type rubber-metal connections.

IPC: H04M3/523
Filed: 1984-11-22
Abstract: The distribution of calls to switchboard positions of a telecommunication system, particularly a telephone switching system, takes place in such a manner that first the switchboard position stored at the first location in a trunk group memory containing the switchboard positions in the order of allocation is checked for allocatability in a position data memory, the field allocated to the type of call of the respective call being checked for a first identification indicating the operating mode of the respective switchboard position, for a second identification indicating the number of maximum permissible calls on hold and for a third identification indicating the number of calls on hold at the switchboard position in the position data memory which has a memory area for each switchboard position and corresponding fields for each type of call within the memory areas, and if a call can be allocated, it is allocated and the address of the switchboard position is deleted at the first location and entered at the last location in the trunk group memory. The call itself is transferred to the switchboard position and there stored in a call-type-individual memory. Non-allocatable calls are stored in a queuing memory and, after a call has been allocated by a switchboard position, are supplied again to the call distribution system. The same occurs when a switchboard position is disconnected, all calls stored at the switchboard position being supplied to the call distribution system again.
