Patent DE-4324296-A1 (DE)
Title: Fingerprint scanning process for identification purposes - has optical scanning to provide data pattern in CCD memory that is processed to obtain X and Y axis phase spectral data for comparison
Inventor: HAMADA TOSHIO
IPC: G07C9/00
Filed: 1993-07-20
Abstract: An impression of a finger print is obtained by pressing the finger (11) against the surface of a triangular prism (12) that is illuminated by a light source (13). The light is reflected off the surface (123) of the prism onto the surface of the finger and is redirected to a CCD memory module (14). The information is stored in matrix form and is available as X and Y axis data. The data is processed to provide phase spectral data for both X and Y directions. This spectral data can be used as stored reference data for comparison with that obtained when a new finger print is entered.

Title: Thin film photovoltaic converter mfr. for mass production of solar cells - has flexible carrier guided into airtight coating chambers having sealing mechanism which adheres to carrier at inlet and outlet
Inventor: SASAKI TOSHIAKI
IPC: H01L31/0392
Filed: 1993-07-20
Abstract: The method involves guiding the flexible carrier (1) into different coating chambers (31, 32, 33) arranged in a line.

Patent DE-4414449-A1 (DE)
Inventor: KEINATH ARMIN DR
IPC: G06K7/10
Filed: 1994-04-26
Abstract: The invention relates to an opto-electronic device for recognising marks having defined contrast patterns, with a transmitter emitting a light beam and a receiver. The transmitted beam is moved periodically over the marks by means of a deflecting device, whereby the received beam reflected by a mark exhibits amplitude modulation according to the contrast of the marks and dependent upon the spatial intensity cycle of the transmitted beam. The received light is converted in the receiver into an analog received signal. The analog received signal is converted in an n-bit analog-digital converter (15), the word width of which is n greater than one, into a digital received signal which is taken to an digital filter (16) with a set of factors changeable in time. The various sets of factors of the filter are selected so that the transmission characteristic of the filter (16) for the individual factors substantially correspond to the inverse frequency spectrum of the spatial intensity distribution of the transmitted beam (8) at different distances from the device (1).

Title: Gasifying process for waste matter in slag pool
Inventor: ALBRECHT JOHANNES DR
IPC: F23G7/00
Filed: 1994-07-13
Abstract: The gasifying process involves gasifying waste matter in a reactor with a slag pool at temp. 122-1600 deg.C. The slag pool consists at least partly of the slag formed from the oxidation of the waste matter. Some of the oxygen-containing gas, to maintain the temp. in the pool, is introduced through under-pool jets coming out in the pool, while the rest of it is introduced through above-pool jets. Ten to fifty percent. of the oxygen-containing gas goes through the under-pool jets, creasing slag foam. The waste matter from outside is fed into the slag foam, which is at least 30 cm. thick.

Title: Semi=trailer coupling with safety=catch release
Inventor: HAWTHORNE V TERREY
IPC: B62D53/12
Filed: 1994-10-06
Abstract: The coupling has a claw securing a kingpin and an actuating rod automatically releasing the catch. The rod (102) has a handle (108), top and bottom sections and a coupling section, also a shaped segment joining the bottom and coupling sections together. It passes through an opening in an edge (44) on the coupling (24), the coupling section extending through a passage formed by a lever coupled to the claw. The top rod section is mounted on the bottom one near the coupling and has a first ramp face at one end, there being a second one on the catch, which pivots on the outside edge surface and engages with the rod. On moving the latter, the ramp faces bear against each other and swing the catch into the release position. At the same time the rod is turned os that its top section can pass through the edge opening and hold the catch in the free position.
Patent DE-4437345-A1 (DE)
Title: Decontamination of porous waste materials, esp. plaster work covering walls
Inventor: DONNER SIEGFRIED
IPC: A62D3/00
Filed: 1994-10-19
Abstract: In the decontamination of porous waste materials esp. plasterwork covering walls, the novelty is that the materials to be decontaminated are in a room, in which the atmosphere has a reduced oxygen partial pressure and raised temperature. The oxygen component is reduced by means of a gas flame burning in the enclosed room at a temperature which precludes the production of dioxin. After it has separated from the wastes, the gas effluent is either exhausted to the outside or returned to the decontamination chamber.

Abstract: A retaining clip designed for holding heating tubes in a floor heating system comprising spring-loaded arms (13, 14) which surround recesses (15) in which heating tubes of varying cross-sections can be inserted and held there securely. The secure holding is ensured in particular by hooked (16, 17, 36, 37) parts which extend from the ends of the spring-loaded arms (13, 14) into the recesses. As a result a low construction height is possible since the spring arms (13, 14) are folded together with the hooked parts (16, 17, 36, 37). At the height of the hooked parts attachment strips (34, 35) applied outside on the spring-loaded arms serve for the secure holding of the retaining clip when it is attached a structural steel grid.
