Title: Control of individual sections in telephone exchange - employing microprocessor for managing each section and including number selection
Inventor: SCHWARZ GUENTER
IPC: H04Q3/545
Filed: 1979-11-26
Abstract: An electronic telephone exchange is controlled by a main computer (CC) with subordinated microprocessors controlling individual sections (00-30) of the exchange. The microprocessor (SGP) is also used for number generation and transmission instead of the computer or special appts. The processor (SGP) attends to number generation at intervals between normal duties. If the instruction memory (ASP) contains an order from the computer it is detected by the processor and the number generation commences at a set rate. Pulses are transferred to an output unit (I/Os), and from there to the designated section (00-30) at a rate and time set by the clock in the computer. Number generation is in intervals. The number of selection impulses transmitted is recorded in an auxiliary memory (ZS). At the start of each number generating time the processor checks both memories. The memories may form a part of a multipurpose memory (M) associated with the normal functions performed by the processor.

Title: Extrusions withdrawal mechanism - with one of two endless units compensated in motion for thickness differences
Inventor: SATZINGER DIETER
IPC: B29C48/355
Filed: 1979-11-28
Abstract: A withdrawal mechanism for extruded plastic sections and tubes consists of at least two endless units to grip and forward the extrusions. The lower unit runs on stationary supports but the upper unit is supported on two hinged two-armed levers. Power cylinders effect the swinging lever motion. At least one of the levers supports the upper unit on an element which is designed for a limited relative movement away from the parallelogram principle of the levers. The extruded product is withdrawn by a lower (2) and an upper (1) endless conveyor unit. The upper unit can be raised in the direction of the curved arrows by two-armed levers (3,4), hinged to pivots (31,41) to form a parallel motion linkage which is actuated by two power cylinders (6,7). This automatically compensates for any thickness differences of the extrusions, specially at the beginning of the extrusion operation.

Title: Temp. controller for protection switch - has snap-action spring for switch which prevents return to on-position from off-position
Inventor: KIRCHERER ROBERT ING GRAD
IPC: H01H35/26
Filed: 1980-03-19
Abstract: The temp. controller has a snap-action spring-loaded switch (12) acted on by an expansion element and a setting element. The controller is modified so that it acts as a protection switch. This is accomplished by making the distance between the stop (60) supporting the free end of the snap-action spring (13) in the 'off' position and the neutral snap-over position of the spring so large that the spring does not return the 'on' position after once having attained the 'off' position. The stop can be moved by a sprung lever (61) whose free end lies near the setting element (36) and that is pivoted by a setting knob (63) fitting axially onto the setting element. The downward movement of the knob by rotation causes the distance to be reduced.

Activities exemplified include stimulating growth of plants and yeasts; liver-protecting effect; inhibiting enzymes such as amino acid deaminase, insulinase (insulin-stabilising effect) or amino acid decarboxylase (prevention of enterotoxaemia); and regulating intestinal microflora (encouraging Lactobacilli at expense of coliforms).
Patent DE-3013336-A1 (DE)
Title: Detection circuit for delay modulated data stream - uses differentiated bit edges as clock pulses, with bit level supplying oscillator in phase locked loop
Inventor: SCHOLZ WERNER DIPL ING
IPC: H03L7/085
Filed: 1980-04-05
Abstract: The circuit is for converting delay modulated signals or the like into logic bit levels. A phase lag or phase advance in consecutive bits of a data stream (DM) reflects in a square pulse (T) generated by a voltage controlled oscillator (VCO) in a phase locked loop configuration with the phase and frequency of the incoming data bits (DM). The data stream is first converted into spikes (d) produced by the bit edges, and which act as the clock pulses. The logic levels produced by the clock pulses (T) when scanned by the spikes (d) yield the exact consecutive logic levels of the bit stream (DM). The circuit has a differentiator (2), an inverter (9) producing negative spikes of equal height (d), both outputs coupled over capacitors (5,8) to a resistor-diode load (10,11), the diodes being voltage biased (17). The voltage (U) applied to the oscillator (4) depends partly on the bias voltage produced by operational amplifiers (24,26) as set by potentiometer (34) and partly on the delayed, or accelerated spikes da or db in the form of low frequency voltage waves. To stabilise these variations into a steady phase and frequency follower voltage the spikes are also fed to the operational amplifiers.
