Title: Verfahren zur bestimmung der fremdstoffverfluechtigung
Inventor: KERBE FRIEDMAR
IPC: G01N24/10
Filed: 1988-07-21
Abstract: Die Erfindung betrifft ein Verfahren zur qualitativen und quantitativen Bestimmung der Fremdstoffverfluechtigung aus Stoffgemischen bei der Herstellung von Oxidkeramik in Abhaengigkeit von den Sinterbedingungen, das zentren- und elementspezifisch mit hoher Empfindlichkeit und zerstoerungsfrei arbeitet. Das Verfahren ist daher sowohl zur Qualitaetskontrolle als auch zur Optimierung der Herstellungsbedingungen einsetzbar. Erfindungsgemaess wird der Gehalt an Fremdstoffen in Probekoerpern durch die Intensitaet eines EPR-Signals der betreffenden Fremdstoffzentren bestimmt, wobei fuer den Fall, dass die Fremdstoffzentren im diamagnetischen Zustand vorliegen, die Probekoerper zunaechst mit Quantenenergien groesser als der Bandabstand des Materials bestrahlt und die Probekoerper unmittelbar nach der Bestrahlung EPR-spektroskopisch vermessen werden.

Title: Verfahren zur gewaesserueberwachung
Inventor: AUGSTEN HELMUT
IPC: E02B15/00
Filed: 1988-07-25
Abstract: Das Verfahren zur Gewaesserueberwachung beruht auf der Schnellbestimmung von Gewaesserverunreinigungen durch Schwermetalle und kann in Einrichtungen des Umwelt- und Gewaesserschutzes angewendet werden. Intakte Ganzpflanzen, vorzugsweise Lemnaceen (Wasserlinsengewaechse), werden als Indikatorpflanze benutzt und in das zu pruefende Gewaesser oder in entsprechende Wasserproben uebertragen oder es werden die im Gewaesser von vornherein vorhandenen Organismen untersucht. Die photosynthetische Effektivitaet der Indikatorpflanzen (Verhaeltnis von Photosystem II/Photosystem I) wird ESR (Elektronenspinresonanz)-spektroskopisch bestimmt; sie ist nach Schwermetallbelastung vermindert. Dieser Effekt ist schon nach 15 min Exposition sicher erfassbar und von Expositionszeit und Schwermetallkonzentration abhaengig. Verschiedene Schwermetalle (Quecksilber, Cadmium, Kupfer) zeigen vergleichbare Wirkungen.

Title: Procedure to detect and display outline of moving objects for video camera, thermal imaging camera
Inventor: VILMAR GORDIAN
IPC: G06V10/46
Filed: 2000-02-03
Abstract: Procedure is performed in cycles to make moving objects stand out from background. Image contents of number of temporal sequence of single images are Fourier transformed to provide power spectrum. Power spectrum are compared with frequency band specific threshold values. Overstepping of threshold is added to last image. Envelope of last image provides rough contour. Image content of sequence of single images are Fourier transformed. Each single image is divided into equal image segments, power spectrum of image segments having same image coordinates, is determined and compared with frequency band specific threshold values. Overstepping of the threshold value in relation to image segment coordinates, is added to the last single image of the temporal series, whose envelope provides a rough outline. Adaptive scenery forming static background, is subtracted from image content of the last single image of the image area enclosed by the rough outline, this causes a fine outline surrounding the object to be inserted into the last image of temporal sequence.

Title: Liquid sample processing apparatus has two-part housing locked together by compression forces through their surface structures to contain membrane with seal for concentration and/or cleaning of macro-molecules
Inventor: VASSAROTTI VINCENZO
IPC: B01D63/00
Filed: 2000-02-08
Abstract: The apparatus to concentrate and/or clean macro-molecules in a solution uses filtration with a membrane (15), with a concentration chamber for the liquid sample and a filtrate chamber, separated by the membrane. The seal (7) is an elastic O-ring, or a flash of elastic material as an integral component of at least one of the chambers. The housing has a ring shape, with a fitting or conical inner surface, and at least one of the chambers has a fitting or conical outer surface where they work together as wedges on assembly of the apparatus to give the required compression forces to lock the housing sections together. A number of concentration chambers can be assembled for the simultaneous filtration of a number of liquid samples. The apparatus has a support (6) with a number of openings to carry a sealing mat with passage openings aligned with the support openings. Cuffs are fitted over the sealing mat with a larger inner width than the width of the openings, to form a laying surface round each opening, of separate flat membranes. A plate with a number of parallel chambers, open at both ends, contain the liquid samples and are pushed into the cuffs until their lower ends rest on the membranes. The two-part housing (2), placed over the plate, has a number of passages aligned with the chambers in the plate, for the liquid samples to be inserted from above to be filtered and flow down into the chambers. The closed housing is pushed into place over the assembly to exert compression forces between the parts and force the membranes against the laying surfaces in a fluid-tight seal, and the passage openings are all in alignment in a vertical flow path for the samples. The openings in the support are fitted with outlets for the filtrate.

The null crossing of the induced voltage is monitored after switching off a current-carrying stimulation winding at the phase junction (Ph1-Ph4) between the stimulation winding and end stage and depending on the null crossing a commutation signal for the control unit can be derived for to supply current to the next winding in the cycle.
Patent DE-10019788-A1 (DE)
Inventor: GROSMANN WALTER
IPC: B23Q1/62
Filed: 2000-04-20
Abstract: The invention relates to a machine tool, comprising a machine frame, a support which is located on said machine frame and which has a first workpiece or tool holder; and a compound slide system which is located on the machine frame and which has a second workpiece or tool holder that can be displaced by means of the compound slide system within a range of movement on a compound slide displacement surface. The aim of the invention is to improve a machine tool of this type in terms of the characteristics of the compound slide system. To this end, the compound slide system comprises two slide elements, one of which is supported on the machine frame and the other of which supports the second holder. The slide elements are guided in such a way that they can be moved towards each other by means of a single two-dimensional guide that can be moved in the direction of both compound slide axes of motion. Said guide determines the precision of the guiding of the second holder parallel to the compound slide movement surface. A drive device is also provided and enables the slide element that supports the second holder to be moved and fixed in relation to the other slide element in both directions of movement of the compound slide, with defined alignment of the slide elements with each other.

Title: Control method for IC engine uses variation in engine compression and alteration of crankshaft synchronization to change their relative positions
Inventor: KLAIBER GERHARD
IPC: F02D15/02
Filed: 2000-04-20
Abstract: The engine has two synchronized crankshafts (11,12), driven by a piston (2) via two connecting rods (8,9). Control is via varying the compression of the engine.
