Abstract: FIELD: checkout technique.  
     SUBSTANCE: invention relates to the field of checkout technique and concerns a method for processing images of speckle structures. The method consists in processing images of speckle structures formed by nanoparticles of ferrofluid placed in a magnetic field formed in laser radiation transmitted through a cell with ferrofluid or reflected from speckle structures. Images are recorded using a camera without focusing optics with autofocus disabled and processed using the RGB color space. To exclude the influence of the intensity of channels B and G associated with the hardware completion of the computer image to improve its perception by the eye, the brightness, color gamut and shades are aligned to the average value. The remaining part of the light noise is compensated by adjusting the RGB channels. In the case of using high-intensity laser radiation to compensate for noise associated with the hardware completion of the computer on the G and B channels, the curves of the RGB channels are adjusted. At the final stage of processing, the choice of the color radiation intensity from the pixel sequence number is implemented.  
     EFFECT: improving of the obtained images quality.

Abstract: A ship with special features for mining the ocean floor while operating in water depths in excess of 18,000 feet. These include first, a very large well in the center of the ship, passing through, but enclosed by the hull. The well is closable across the bottom by movable gates. Second, a pipe-handling system for moving large diameter mining pipe sections between the storage hold in the hull and the rig floor in the derrick where they are joined to or disconnected from the existing pipe "string" from which the mining machine is supported. Third, the lift system which operates to raise or lower the pipe string on continuous feed basis. Lastly, the derrick, derrick pipe-handling equipment and entire lift system are motion compensated in roll, pitch and heave such that the derrick and suspended pipe string remain vertical with respect to the earth, isolated from the actual sea-induced motions of the ship. The entire motion compensated system is supported over the center well by a large structural A-Frame.

Bekannte derartige Objektive bestehen aus vier Gliedern.  Bei der Aufgabenstellung in der Reproduktionstechnik bestehen jedoch Probleme der Verzeichnung in den Extremstellungen da die sphaerische Aberration und der Astigmatismus sich   nur bedingt korrigieren lassen. Aufgabe der Erfindung ist es, ein viergliedriges Reproduktionsobjektiv zu schaffen, bei dem die Groesse der Einzelbrechkraefte eine sehr geringe Verzeichnung ergibt, wobei die zulaessigen Toleranzen der einzelnen Glieder noch eine wirtschaftliche Fertigung zulassen. Weiterhin soll durch ein entsprechendes Bewegungskonzept der Astigmatismus in allen Gebrauchsstellungen des Objektives gut korrigiert sein.

Abstract: Bei zahnärztlichen Handstücken mit einer gegen den zugehörigen Versorgungsschlauch frei verdrehbaren Griffhülse (1) hat sich gezeigt, daß die Handhabung des Handstücks am Patienten verhältnismäßig unbehindert durchzuführen ist, daß aber der Lichteinfall an der zu behandelnden Stelle des Patienten mit den bisher üblichen Lichtquellen oft nicht ausreicht. Um hier Abhilfe zu schaffen, wird ein die Griffhülse (1) im wesentlichen axial durchsetzender, strangförmiger, an eine Lichtquelle anschließbarer Lichtleiter (15) verwendet, der in der Griffhülse (1) wegen der freien Drehbarkeit des den Versorgungsschlauchanschluß bewirkenden Anschlußstückes (5) gegenüber der Griffhülse (1) unterbrochen ist oder endet. Durchfluß des Lichtstrahles durch die Griffhülse (1) wird bei einem solchen zahnärztlichen Handstück nun dadurch bewirkt, daß in dem Anschlußstück (5) ein Lichtbeaufschlagungselement angeordnet ist, das entweder der Abschnitt (15b) des strangförmigen Lichtleiters (15) oder eine Glühbirne (22) mit den zugehörigen Anschlußelementen (23, 24, 25) sein kann.

Abstract: Eine Scheibenkupplung (10) für ein Kraftfahrzeug besitzt eine Kupplungsscheibe mit radial verlaufenden Lappenabschnitten (28), die Reibbeläge (39) aus einem geeigneten Material tragen. Die Reibbeläge sind auf Dämpfungsmitteln (38, 53, 68) montiert, derart, daß sie mit den Eingriffsflächen der Kupplung einen Kontaktbereich veränderlicher Oberfläche bilden, um zur Ratterverringerung die Kupplungskapazität beim Einrücken herabzusetzen. Wenn das zu übertragende Drehmoment größer wird und der Einrückvorgang sich fortsetzt, wird die Kupplungskapazität durch eine Deformation der Dämpfungsmittel vergrößert, so daß sich die Reibbeläge gegen die Eingriffsflächen plattdrücken lassen und somit einen größeren Kontaktbereich bilden.
