Patent DE-1815727-C1 (DE)
Title: Target control system for steered torpedo - uses acoustic target location data and switches from navigation mode to curved steering mode at given proximity
Inventor: SCHWARZ HANS-DIETER DIPL-ING
IPC: F41G7/22
Filed: 1968-12-19
Granted: 1985-10-31
Abstract: The control system uses acoustic target location data allowing the steering to be switched from a given course or a proportional or target area navigation mode to a curved steering mode. The switch on is effected at a given proximity (A) to the target, determined from the remaining time for the torpedo (To) to reach the target point (P). The steering angle for the curved steering path is pref. proportional to the target angle at the switch on point.

Title: Heat exchanger tube
Inventor: MACK ALBERT
IPC: F28D1/03
Filed: 1982-04-30
Granted: 1988-06-16
Abstract: In a flat heat exchanger tube (1) produced from a sheet-metal strip, one wide wall (3) of the two is bent over and overlapping lateral sections (6 and 7) of this strip are assembled, being soldered to one another. The overlapped lateral section (7) is held in contact with the lateral section (6) located thereabove by means of a resilient support element which is formed by the angular edge strip (10) of the overlapped section (7) which is supported by its rounded end (11) on the other wide wall (2). The non-positive contact of the lateral section (7) is ensured before the soldering of these two lateral sections and during this process. A perfect soldered joint is achieved even if before soldering the tube is plugged into tube bottoms or finned metal sheets, or zig-zag-shaped gills bear against its wide walls, these components being connected to the tube and the lateral sections (6 and 7) thereof being connected to one another in a single soldering process. It is possible in this way to apply flux soldering, which is economic, since because of the special configuration of the support all the flux can be rinsed from the tube after soldering. <IMAGE>

Title: Process for installing at least one pipeline for supplying flue gas into the interior of an existing cooling tower, and apparatus for carrying out the process
Inventor: ERNST EGON
IPC: F28C1/00
Filed: 1984-04-07
Granted: 1985-08-29
Abstract: The invention relates to a process for installing at least one pipeline for supplying preferably purified flue gas into the interior of an existing cooling tower, the pipeline being located above the cooling-tower internals used for heat exchange and penetrating the cooling-tower shell, preferably consisting of concrete, in the region of an opening. In order to be able to install and fit the pipeline during cooling-tower operation, after completion of preparations which only requires a short shutdown period of the cooling tower, the pipeline is assembled from individual lengths of pipe outside the cooling tower, in front of the opening in the cooling-tower shell, and is fed section by section into the cooling tower. The pipeline is supported on props, erected in the cooling tower, by means of roller bearings which allow an axial and rotary movement of the pipeline. The pipeline, provided with at least one radial discharge opening, is fed into the cooling tower with a downward-pointing discharge opening and, in the final state, is turned such that the discharge opening points upwards.

Patent DE-3939484-C1 (DE)
IPC: G09F25/00
Filed: 1989-11-29
Granted: 1991-04-25
Abstract: A process for generating a entertainment audio signal interrupted by advertising audio signals, in which pilot signals associated with the advertising audio signals cause switching between the entertainment audio signals and the advertising audio signals, makes it possible to broadcast different radio programmes of the desired acoustic quality in a shop, by means of a carrier frequency. To this end, a high-frequency control signal is generated from advertising audio signals and pilot signals which precede or follow the advertising audio signals, the control signal and preferably the entertainment audio signal are modulated to a high-frequency carrier signal, possibly with several channels for the separate recovery of the signals, the modulated carrier signal is transmitted, the transmitted carrier signal is demodulated and, if necessary, the signals are separated from each other. The pilot signals of the transmitted control signals are monitored for the presence of fading or flashback conditions. If fading conditions are present, an advertising audio signal forming part of the control signal, which follows the pilot signal, is faded into the added entertainment audio signal and the resultant signal is reproduced. If flashback conditions are present or if the advertising audio signal is interrupted for a certain time-interval, the entertainment audio signal is faded in and the resultant signal is reproduced.

Title: Container for condensed milk or mayonnaise, with opening enclosed by flat edge, has cover sealing opening adhered to edge, cover including pull-tab
Inventor: WILLEMSEN LOUIS RINZE HENRICUS
IPC: B65D77/20
Filed: 2000-10-05
Granted: 2002-04-08
Abstract: The container has an opening enclosed by a flat edge (2), and a cover sealing the opening adhered to the edge. The cover has a pull-tab (4) extending outside the edge. The cover is made from a flexible, tearable material, and the pull line (6), which extends between the far end of the pull-tab and the middle of that part of the edge adjacent to the pull-tab, extends at a distance from the center of gravity of the opening.
