Abstract: Digital processor for surveillance radar, in particular for air traffic control, constitude by a set of transverse fitters which cover the unambiguous Doppler frequency interval with Doppler frequency response selectable for each filter in order to adapt the filtering to the interference characteristics produced by unwanted echoes (clutter). At the output of the filters there is the extraction of the modulus and the comparison with the detection threshold, possibly adaptive. The result is sent to the overall detection logic.

Abstract: For binding the pollutants in flue gases downstream of combustion plants, especially for flue gas desulphurisation, it is proposed to admix NaHCO3 and/or Na2CO3 as an additive to the flue gas cooled to about 120 DEG  to 320 DEG C and to precipitate the resulting salt in a fabric filter. To facilitate purification of the salt formed and its further use, the fly ash is already precipitated before the additive is charged, and the residence time on the fabric filter is thereby also extended by increasing the period between two cleaning steps, so that the result is an improvement in the utilisation of the additive. <IMAGE>

IPC: E02D5/80
Filed: 1986-10-01
Granted: 1989-12-28
Abstract: For the installation of an anchor member at a location below a water level through a retaining wall into a soil formation for supporting the wall, a drill mount is pivotally mounted about a horizontal axis on a retaining member secured to the wall. The drill mount can be pivoted between a drilling position inclined downwardly toward the wall and an upwardly extending loading position where the drill mount is accessible above the water level. A cable line secured to the drill mount pivots it between the drilling and loading positions. A drilling machine is displaceable on a sliding carriage along the drill mount. A drilling tool inserted into the drilling machine is used to drill an opening through the wall. Subsequently the drilling tool is replaced by a borehole pipe and the pipe is driven through the wall opening into the soil formation. With the borehole pipe inserted, an anchor member can be placed into the pipe and by withdrawing the pipe and grouting around the anchor member at the same time, the installation of the anchor member can be completed.
