Title: Process for blowing coal dust or the like into a burner, and solids firing device for this purpose
Inventor: VONNEGUT KLAUS A
IPC: C21B5/00
Filed: 1982-07-30
Abstract: In a process for controllably blowing coal dust or the like solid fuel into a burner, solid fuel from a fuel supply is mechanically conveyed in a metered quantity into a mixing region for a respective burner (18) or burner group (20) and is mixed there with an air stream. Preferably, the fuel conveying and mixing can either take place continuously or intermittently. According to an advantageous development of the process, the fuel conveying takes place from an intermediate fuel supply, available beneath the mixing region, to an air stream located higher, the fuel expediently being loosened before the beginning of its mixing with the air stream. A solids conveying device which is particularly suitable for carrying out the previously mentioned process is equipped with at least one metering device (5) and also with a container (4) containing the fuel. The apparatus thus has at least one metering device (5), which has a metering screw (6) engaging in the available fuel. A particularly advantageous development consists in that the apparatus has an intermediate feed container (4) which has a loosening device (10) for the fuel. The worm wheels (7) of the metering screw (6) can also be constructed with a pitch which increases upwards. A retaining space (73) for the fuel is provided between the uppermost screw turn (75) of the worm wheel (7) and a mixing channel (33) of a metering housing (32) of the metering device (5). Space is thus created, for example to make a larger quantity of fuel (74) available for an air pulse. <IMAGE>

Patent DE-3239403-A1 (DE)
Title: Method for determining gun sites
Inventor: FISCHER JOHANNES DIPL ING
IPC: G01S5/22
Filed: 1982-10-25
Abstract: For acoustically locating guns, at least two measuring crosses of four adjacently arranged microphones are mounted in the terrain. Muzzle reports of the guns are received by the microphones and transit times between received signals of diametrically opposite microphones of a measuring cross are determined. The arc tangent of the quotient of the transit times supplies a direction-finding angle between measuring site and gun. The determination of the transit times is problematic if the variation with time of the received signals to be compared is different due to, for example, weather influences. By correlative processing - conjugate complex multiplication of the frequency spectra of the received signals and inverse transformation of the cross spectrum - the cross correlation function of the received signals is obtained, the major maximum of which specifies a search time range. The cross spectrum is multiplied by a frequency function, preferably the Hilbert transformer. The inverse transform of this product, possibly the Hilbert transform of the cross correlation function, exhibits a steep zero transition at the point of the major maximum of the cross correlation function within the search time range. The zero transition is determined and supplies the transit time. This method is used in artillery reconnaissance.

Title: Ultrasonic transmitting/receiving system
Inventor: SOLDNER RICHARD DIPL ING
IPC: B06B1/06
Filed: 1983-03-25
Abstract: This system operates in reflection mode and has at least one transducer for focused radiation of ultrasound of defined frequencies. According to the invention, the transducer (1, 11, 31-34, 51-59, 61-69) is designed for generating different ultrasonic frequencies, in such a manner that the transmitting/receiving foci (fi) for the different frequencies (Fi) of ultrasound radiated into the tissue under examination are allocated at different depths and especially the lower frequency components (Fi) form a focus which is deeper in the tissue, a depth-or-time-related selection of the individual frequency components (Fi) being affected during the receiving phase. The ratio of the ultrasonic frequencies is preferably the inverse of the ratio of the focus distances in the tissue. A depth-dependent frequency window suppresses echo components which do not originate from the area of focus. Such frequency weighting has the advantages of automatic dynamic focusing in the transmitting and in the receiving case, of automatic dynamic aperture adaptation with respect to depth and of an effective automatic suppression of multiple echoes and sidelobes. <IMAGE>
