Patent DE-4213340-A1 (DE)
Inventor: ACOSTA JORGE LUIS
IPC: G06K7/10
Filed: 1992-04-23
Abstract: A laser scanner produces generally parallel scan lines at a target by moving, by dithering, rotating, translating, or wobbling a secondary mirror 51B, 132, optical device, or primary optical element in an optical arrangement which redirects a laser light beam to generate a scan pattern. The laser scanner typically includes an optical device 36 or primary optical element which receives and reflects laser light beams from a laser light source, and a multiplicity of secondary mirrors 51 disposed in positions relative to one another. One or more of the secondary mirrors 51B are mounted and dithered or continuously rotated to generate the scan lines. Other optical elements, such as a primary optical element or device may be rotated, dithered or wobbled in their mountings to produce the scan lines. <IMAGE>

Title: Sludge drying - using centrifuge for initial water extn. followed by feeding DC current through electrodes pressed against caked sludge for scraper extn.
Inventor: KLAY NORBERT
IPC: C02F11/15
Filed: 1992-05-07
Abstract: To extract water from sludge, with a combined mechanical action and treatment with an electric current, the sludge is initially treated mechanically in a scraper centrifuge to give the first water removal. Electrodes (5-8) are then pressed against the built-up sludge (4) forming a wall layer. A DC current is fed to the electrodes, to complete the water removal from the sludge. When dry, the caked sludge (4) is scraped out of the centrifuge. Pref. after the initial water removal, electrodes (5,6) moving with the centrifuge are pressed radially against the caked sludge (4) while rotating at centifugal speed and DC current is applied to complete the water extraction and, when finished, the electrodes (5,6) are withdrawn radially inwards in a short movement. A hollow scraper blade, mounted to the interior of the centrifuge, is extended radially through the gaps between the electrode sections to detach the caked sludge (4) for removal through the hollow scraper and a hollow shaft (10). When the initial drying is complete, the centrifuge is at rest and the electrodes (5-8) are moved to press against the caked sludge (4), and a current is fed to them. After electro-kinetic drying, the electrode sections are withdrawn, and a scraper detaches the caked sludge (4). The vol. of sludge fed into the centrifuge is set to give predried sludge in caked (4) thickness of 3-20mm, to be subjected to DC at 5-50V. ADVANTAGE - The process gives a dried sludge material with a high dry matter content.

Patent DE-4239361-A1 (DE)
Inventor: BENDEL KLAUS DIPL ING
IPC: F04B53/04
Filed: 1992-11-24
Abstract: The invention relates to a pumping set for a controlled braking system (ABS/drive slip control). In such an assembly, brake fluid forced by the piston accumulates in the spaced around the eccentric (4) and, when in sufficient quantity, is pressurised by the moving pistons. The use of a simple outlet channel in the environment raises problems, at least in immersion-proof vehicles, through the penetration of moisture and dirt. The invention helps here by the introduction of a check valve (15) fitted in the outlet channel which is so designed that it opens under the weight of the accumulated brake fluid and reliably prevents the ingress of dirt and moisture in the opposite direction.

Title: Tunable laser emitting beams with two different wavelengths
Inventor: NIKOLAUS BERND DR
IPC: H01S3/1055
Filed: 1993-01-22
Abstract: The adjustable two colour laser has a lasing medium (10), an end mirror (12) and a wavelength selective element (14). The selection characteristics of the latter (14) depend amongst other things on the angle of incidence (alpha) of the beam. To improve selectivity, a beam deflector (16) is used.A dispersive element (34) is inserted between the wavelength selective element (14) and the deflector (16) to split the beam into partial beams (30, 32). These are incident on the wavelength selective element (14) at different angles. Thus, the splitting of the selective characteristics is such that the autocollimation function for both partial beams (30, 32), both for equal and different wavelengths, is satisfied. The dispersive element (34) splits the laser oscillator into two coupled oscillators which can be tuned over the whole bandwidth of the lasing medium.

Title: Method for determining the surface quality of a test specimen (test piece)
Inventor: KASTENMUELLER ANTON
IPC: G01B7/34
Filed: 1993-05-11
Abstract: In a method for determining the surface quality of a test specimen, the surface of the latter is scanned along a predetermined path by a scanning device (10) which fixes two reference points (12, 14) on the surface separated from one another by a distance L. A scanning element (sensing element) (18) determines the vertical distance between a reference point (20) lying on the surface and the middle of the connecting line between the reference points (12, 14). The distance is converted at prescribed path intervals into an electric signal (S) which is subjected to a Fourier transformation. The Fourier coefficients (ak, bk, ck) relating to the local wavelength lambda  which are determined in this case are multiplied by corresponding values of a correction function (K). The corrected Fourier coefficients (ak', bk', ck') are evaluated for the purpose of determining the surface quality. <IMAGE>

Title: Process and assembly to separate metals from refuse - reduces volume of refuse requiring treatment and disposal as metallic waste by flow sub-division and recirculation of non-metals
Inventor: FOLSBERG JAN
IPC: B07C5/344
Filed: 1993-05-24
Abstract: In a process and assembly to separate waste metal particles from refuse, the metallic content is regulated (1) at a station and the non-metallic flow is diverted to the next treatment stage (21), while the metallic content is collected (13). The novelty is that materials collected (13) are passed to a second flow control station (3) at which the metallic content is again regulated, and where the metallic content is diverted. USE/ADVANTAGE - The process separates metallic residues from refuse. The quantity of material which must be removed from the overall volume of refuse is reduced, thus minimising the volume of material to be treated as a metallic residue.

Title: Protective circuit arrangement for electronic subscriber line interface circuits
Inventor: MANICKE ULRICH DIPL ING
IPC: H04M3/18
Filed: 1993-08-07
Abstract: Electronic subscriber line interface circuits, SLIC, (SLIC1 ... SLICn) are particularly susceptible to, and their function is particularly jeopardised by, overvoltages which occur primarily as a result of the effects of lightning on the subscriber connection lines (Ltg1 ... Ltgn). To protect against overvoltages, circuit arrangements with expensive special components and/or expensive additional circuits are known. The object of the invention is to indicate a protective circuit arrangement with low-cost components which guarantees common protection of a plurality of subscriber line interface circuits (SLIC1 ... SLICn). For this purpose, a conventional mains thyristor (Th) is used according to the invention whose gate control voltage (UG) or cathode voltage (UK) is compared by means of a comparator (K) with a reference voltage (UV) in the blocked state and, in the event of overvoltage, in the through-connected state. In the event of overvoltage, the comparator output voltage causes the subscriber line interface circuits (SLIC1 ... SLICn) to be isolated via a control input (IST) so that the current level falls below the level of the holding current of the thyristor (Th) and the latter reverts to the blocked state following the absence of the overvoltage. <IMAGE>

Title: Engine-operating system on mixed fuels - adjusts performance characteristics only after mixture proportions have altered for predetermined time.
Inventor: KAMMANN UWE DIPL ING
IPC: F02D41/00
Filed: 1993-08-11
Abstract: The system is esp. for engines running on a mixture of petrol and alcohol. Performance characteristics stored in a controller are used to give the ideal mixture of fuel and air for different operating conditions, dependent on the mixture proportions measured with the engine running. Adjustment of the characteristics takes place only after the alteration in the proportions measured with the engine running has continued for more than a predetermined period. The length of this period can be determined by the degree of alteration in the proportions. USE/ADVANTAGE - IC engine-operating system using mixed fuels, eg. petrol and alcohol, avoids unstable engine operation.
