Patent DE-3812416-A1 (DE)
Title: Safety power interruption
Inventor: MOESSNER GERHARD
IPC: H02H5/00
Filed: 1988-04-14
Abstract: The invention relates to a method and an arrangement for automatic interruption of the power supply in secondary distribution systems in the event of inadmissible ambient conditions. In this case, an electric switch (14) installed for the purpose of electrically safeguarding the secondary distribution system is connected to a detection device (12) which monitors the ambient conditions and, when inadmissible variations occur, generates a signal which is used for operating the electric switch (14). The electric switch (14) is tripped by means of the signal, which causes the current supply to be broken. Suitable detection devices (12) are those for detecting gas concentrations, temperature variations or those changes in the ambient conditions where continued use of the electrical system may have detrimental effects on what happens. Tripping of the electric switch (14) may here be made mechanically or electrically. In addition, acoustic or optical warning may be provided. <IMAGE>

Title: Circuit arrangement for the phase synchronisation of clock pulses
Inventor: HOFBAUER RUDOLF DIPL ING
IPC: H04L7/033
Filed: 1988-05-27
Abstract: The circuit arrangement represents a phase control loop serving for the phase synchronisation of clock pulses, having a controllable clock oscillator (VCXO), a frequency divider (FT) connected downstream thereof and a phase discriminator (PLL). From this phase discriminator, the clock oscillator receives control signals fed via a low-pass filter, which permit phase control within a prescribed proportional range. Additionally, a control device (SE) is provided for coarse phase synchronisation, which control device determines a phase deviation lying outside a prescribed limiting value and, in the presence of such a phase deviation, modifies the clock pulse train emitted by the clock oscillator in such a way, that additional clock pulses are inserted into this clock pulse train or clock pulses are removed from this clock pulse train, according to the amount of the phase deviation, in each case according to the direction of the phase deviation. <IMAGE>

Title: Freely addressable peripheral transmitters
Inventor: AXINTEANU LUCIAN DIPL ING
IPC: H02J13/00
Filed: 1988-05-28
Abstract: A unique address, which can be set using coding switches on this peripheral transmitter, is assigned to peripheral devices such as:   - limit switches, press switches, selector switches, floating switches, buttons, etc., and analog sensors on the sensor side, - protectors, valves, amplifiers, regulators on the activating side.   They are sensibly grouped (up to 16 digital inputs or outputs and 2 analog inputs or outputs per peripheral transmitter). The data collector is informed of each change of a bit in real time, via the data transmission device, with difference phase modulation and two working sequences. Thus there are no cable connections between the grouping point and the freely programmable control device or computer. Considerable cost savings in industry and an increase in performance in the economy generally are thus achieved.

Title: Adder circuit using 5211 code
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1988-08-14
Abstract: The adder circuit according to the subject of the invention is not a standard adder circuit but a special adder circuit, which firstly has a dual full adder (7) to process the value 5, and secondly has one dual full adder each to process the values 1 and 2. If a carry with the value 4 occurs in the dual full adder (6), which processes the value 2, and this should be processed in the dual full adder (7), the remaining sum must be reduced by the number 1, so that a wrong sum is not formed. Circuit (2) is arranged for this reduction of the remaining sum by the digit 1. It is triggered simultaneously with high potential, and thus reduces its remaining sum value by the digit 1, because the negating circuit (74) is then at a low potential at its output. <IMAGE>
Patent DE-3827648-A1 (DE)
Title: Electrical automatic switch
Inventor: GOEHLE ROLF ING GRAD
IPC: H01H71/10
Filed: 1988-08-16
Abstract: Electrical switching apparatuses, especially automatic switches, have magnetic releases (34), with a moving magnet armature which interacts with a release plunger (36), for automatic tripping. In order to avoid possible functional defects, the magnet armature is intended to rest on the magnet yoke when the apparatus is switched off. Resetting devices provided for this purpose for the magnet armature necessitate relatively high release forces for the magnetic release and, because of this, its structural volume must be larger. A novel electrical switching apparatus (31) has a resetting lever (10, 30) which acts briefly on the release plunger (36) of the magnetic release (34) after tripping and resets it to its rest position, so that the magnetic release (34) is in its rest position when the switching apparatus (31) is in its switched-off state as well. The novel resetting lever (10, 30) is provided especially for use in the case of electrical automatic switches (31) with magnetic releases (34). <IMAGE>
