Inventor: HALDER MATHIS
IPC: H01F27/42
Filed: 1984-03-22
Abstract: A balanced Wheatstone measurement bridge (ABCD) is used for fault compensation of the current transformer (1a; 1b), in the side arms of which Wheatstone measurement bridge (ABCD) the secondary winding (1b) of the current transformer (1a; 1b) and three resistors (R1, R2, R3) are arranged and whose first diagonal arm (BD) is connected to a difference input of an amplifier (2), while its second diagonal arm (AC) is supplied from the output of the amplifier (2) via a load resistor (RL). The connection of one of the two poles of the first diagonal arm (BD) to the difference input of the amplifier (2) passes via a high-pass filter (3). A capacitor (C1 or C2) is connected in parallel with either the secondary winding (1b) or the resistor (R2) which is arranged diametrically opposite in the Wheatstone measurement bridge (ABCD). <IMAGE>

Patent DE-3418939-A1 (DE)
Title: Power controller for electrical loads
Inventor: FRANK WILLY DIPL ING
IPC: H02P27/02
Filed: 1984-05-22
Abstract: In the case of a power controller for electrical loads, having a nominal-value transmitter which supplies a nominal voltage which is dependent on the desired power, a circuit is provided which supplies a mains-synchronous, intrinsically changing digital ramp signal as well as a voltage which is a function of the maximum value of the mains-synchronous ramp signal and is used as a reference variable for the nominal value transmitter. A further circuit converts the nominal voltage, which is supplied by the nominal value transmitter, and is part of the maximum value of the mains-synchronous ramp voltage, into a corresponding digital signal. A digital comparator compares the digital nominal signal corresponding to the nominal voltage with the mains-synchronous digital ramp signal and, when the two digital signals are equal, activates a circuit which supplies a triggering current for the power element for the case when the power component is not carrying any load current.

Title: Device for generating fog on theatre stages
Inventor: BIDERBICK MANFRED
IPC: F41H9/06
Filed: 1985-01-24
Abstract: For certain productions, the generation of artificial fog on theatre stages is required. In addition to the fog generation by vaporisation of special oil and carbon dioxide, a process has proved suitable in which liquid nitrogen is sprayed onto the surface of hot water. In this case, the water is in an electrically heatable container. In this process, neither undesired residues and smells are produced, nor is there a fire risk. A certain disadvantage is only the fact that, in a prolonged operation, the water surface freezes and the fog generation thus ceases even if the water is continuously heated. In order to be able to generate fog by this process even over prolonged periods, the heating of the water is effected by an electric continuous-flow heater (14) which is fed from a cold-water container (11) and whose outlet line leads into the container with hot water. This hot-water container (1) also has a discharge opening (9) at the height of the water level (4), from where water flows back into the cold-water container. In this way, the water cooled by the liquid nitrogen at the height of the water level is taken back into the cold-water container and replaced by hot water from the continuous-flow heater, so that the water can no longer freeze. <IMAGE>

Title: Manual starting device with kick-back safeguard for an internal combustion engine
Inventor: REUTER HARALD
IPC: F02N1/02
Filed: 1985-03-15
Abstract: The invention relates to a manual starting device with kick-back safeguard for an internal combustion engine with a hand crank 19, which can be made to engage by way of a starting piece 7 and an axially disengagable override clutch 17 with the free end of a camshaft 2 of an internal combustion engine. The starting piece 7 is connected to a freewheel mechanism 9, the outer ring of which is connected to the housing 1 of the internal combustion engine. In the starting direction of rotation A the freewheel mechanism 9 is released, whereas counter to the starting direction of rotation it fixes the starting piece to the housing 1 of the internal combustion engine. In order to be able to reliably dissipate kick-back energy without damaging the manual starting device and the internal combustion engine and without any reaction on the hand crank 19, it is proposed to connect the starting piece 7 to the camshaft 2 by way of a friction surface under the action of axial force (fig. 1). <IMAGE>
