Patent DE-3620835-A1 (DE)
Title: Method for monitoring a digital hierarchically structured information transmission network
Inventor: WENZEL ROBERT DIPL ING
IPC: H04L1/00
Filed: 1986-06-21
Abstract: Analog transmission paths are frequently monitored by means of so-called line or group pilots. Digital transmission paths are monitored by means of the frame structure of the transmitted digital signal. To ensure that the transmitted signal arrives at the predetermined device, a code identifying the latter is inserted in a time slot of the time division multiplex frame in the multiplexing device and/or line terminating device in a digital information transmission network. Monitoring of the digital information transmission network and control of an equivalent network is possible in a simple manner by separating the code from the information signals and evaluating the code.

Patent DE-3701544-A1 (DE)
Inventor: SPAHN WALTER
IPC: B01D8/00
Filed: 1987-01-21
Abstract: The removal of impurities from exhaust gases takes place by cooling the exhaust gas by means of a circulation gas and condensing out of the impurities in two groups of reversible heat exchangers. Each group consists of two precoolers and one low temperature cooler. While the impurities condense out in one group, they are thawed in the other group. In order to simplify the control, only one precooler is used in each group, which is charged with two inside gases, namely, the exhaust gas and the circulation gas. Only two simple control systems which can be easily program-controlled are then required for the purification process. In addition, the temperature increase of the circulation gas in the circulation gas blower can be utilized for heating up purposes in the group to be thawed.

Patent DE-3801560-A1 (DE)
Title: Acutating device for a Venetian blind with an electric motor
IPC: E06B9/307
Filed: 1988-01-20
Abstract: As has been previously proposed, the slats of a Venetian blind assume an inclination, during lowering, of, for example, 45 degrees and are not pivotable into the closed position until the drawing-up and turning shaft is rotated back in the upwards direction through only a small angle of rotation and is then actuated again in the downwards direction. If the shaft is rotated back through a larger angle, the slats assume the intermediate position again and are lowered further. The invention ensures that the respective angle of rotation is maintained accurately, when the shaft is rotated back, by an electronic circuit arranged between the control station for the motor drive and the drive motor, depending on whether the control station is only touched briefly or is actuated for any length of time in the lowering direction.

Title: Borehole plug with self-restraining tube
Inventor: JAEGER FRITZ
IPC: E21B33/127
Filed: 1988-04-21
Abstract: A borehole plug provided in particular for use in underground mining and tunnelling has an extensible sealing part which is pressed against the borehole wall by consolidating material penetrating into the annular extension space in order to secure the borehole plug on the one hand and prevent the subsequent passage of consolidating material from the hole bottom on the other hand. Reliable and uniform pressing of the sealing part against the borehole wall is achieved, since the pipe piece is designed as a buckle-proof, robust supporting pipe, while the sealing part is a thick-walled tube which is flexible to a limited extent and is displaceably held on the end allocated to the inlet part. If consolidating material is fed into this borehole plug, this consolidating material, after passing the first non-return valve, penetrates through axial and radial bores in the buckle-proof pipe piece into the annular extension space, inflates the sealing part and presses its wall against the borehole wall, the bottom end being partly displaced in the holder so that a uniform inflation effect over the entire length of the sealing part is guaranteed. <IMAGE>

Title: Method for regulating the temperature of the flow or return of closed-circuit heating system and closed-circuit heating system temperature-regulated by the method
Inventor: SCHILLING JUERGEN
IPC: G05D23/19
Filed: 1988-04-23
Abstract: In a closed-circuit heating system having heating elements which are connected to a flow and a return and serve predominantly for the convection of the room air, and having a regulation of the temperature of the flow, controlled as a function of the outside temperature, from a certain limit value of the temperature of the flow the regulation is carried out not linearly but according to a function of higher order, in order thereby to ensure the maintenance of a sufficiently high lift for the convection action in the region of the heat-exchange surfaces of the heating elements, without the need for an arbitrary intervention in the regulating system to do this.
