Patent DE-3150581-A1 (DE)
Title: Control method for remote-control purposes on low-voltage lines
IPC: H02J13/00
Filed: 1981-12-21
Abstract: The invention relates to a method for transmitting signals between a central station and a number of substations for remote-control purposes on low-voltage lines, by means of an RF signal. In this case, the invention makes use of the fact that, in accordance with the postal regulations, emission of a signal is allowed as regularly and as long as desired provided a prescribed transmitted power is not exceeded. In such a method, the transmission reliability is rather inadequate because of the very low permitted transmission level, since the range is also greatly limited because of the different characteristics of the installation network. The object of the invention is thus to increase the range of the transmitted signal by raising the signal level, taking into account the postal and VDE regulations which apply to this. This is achieved according to the invention in that the length of the signal emission and the regularity with which the signals are transmitted are limited in order to be able to achieve a maximum transmission level.

Title: Window
Inventor: HACK GUENTER
IPC: E06B7/10
Filed: 1982-01-05
Abstract: The window frames have venting ducts in the longitudinal direction which are divided by means of heat-exchanging partitions. The individual ducts are connected by means of air-inlet and air-outlet openings to the inside and to the outside. There may also be connected to the individual spaces the spaces between the window panes so as to use the central pane as a heat-exchanging wall. Venting ducts of different frames can be interconnected by means of passages. The airflows directed from the outside inwards or from the inside outwards predominantly cross one another in the lower and upper frame limbs. Venting ducts are also formed between the outer frame and wing frame or between wing frames. The window frames are formed in one piece, or butt-jointed from U-shaped and angled parts having integrated corners. U-shaped profiles are covered in such a way that access can be had to them, the coverings are particularly heat-insulating and soundproofing and may surround the entire construction core. The rabbet-forming slimline profiles of the frame of special material can be placed on the frame construction of inexpensive environment-friendly material, such as wood. <IMAGE>

Title: Method of relieving the drill-head mounting when sinking a drill pipe, as well as a device for carrying out the method
Inventor: JOURDAN KLAUS DIPL ING
IPC: E02D7/22
Filed: 1982-03-29
Abstract: The invention relates to a method of relieving the drill-head mounting when sinking a drill pipe and includes appropriate proposals for the design of a device for carrying out the method. Starting from the known methods of sinking displacement bored piles which have the disadvantages of a necessarily high applied load and the absorbing of a high torque in the drill-head mounting, i.e. in the drilling tower, the object of this invention is to facilitate the sinking of these drill pipes. This object is achieved in that the torque required for sinking the drill pipe (7/8) is partially or completely removed by the torque of a loosening worm (10) which rotates in the opposite direction, is arranged in front of the drill pipe (7/8) in such a way as to be displaceable coaxially to the drill pipe (7/8), induces a displacing resistance and is arranged on a conical supporting arm (9). The loosening worm (9/10) can be inserted into the inside diameter of the drill pipe (7/8) and thus its effective length can be adjusted. The speed ratio between the drill pipe (7/8) and the loosening worm (9/10) can likewise be varied. <IMAGE>
