Title: Method and system for determining the position and alignment of a surface of an object in relation to a laser beam
Inventor: HORVATH CHRISTOPHER
IPC: G01N1/40
Filed: 2003-09-19
Granted: 2012-09-11
Abstract: The present invention generally relates to a method and system for determining the position and alignment of a plane in relation to an intersecting axis and using that known position and alignment to allow for corrections to be made when using the plane as a reference plane. More particularly, the invention relates to a method and system for determining the angle of tilt of a planar surface in relation to a laser beam, and using the determined angle of tilt to calculate a correction factor to be applied to the laser beam. Briefly stated, the method and system ultimately calculates a correction factor, z-offset, that is applied when using the laser beam in a procedure.

Title: Method and device for treating water
Inventor: LAITINEN ILKKA OLAVI
IPC: B01D1/06
Filed: 2004-05-12
Granted: 2011-07-12
Abstract: Purified water for special purposes is produced using a falling-film multieffect evaporator. From the feed water, each effect produces a steam phase and a water phase. The steam phase is used for heating in the subsequent evaporating step, whereby the steam phase condenses to product water, and the water phase becomes feed water for the subsequent evaporation step. According to the invention, the product water may be wholly or partly recycled to the initial feed water, allowing process startup and sterilisation of the plant without conducting hot product water to the drain.

Abstract: The present invention relates to an apparatus for removing a flexible floor covering from a floor. The apparatus has a frame supported on a plurality of castors to allow rolling motion of the frame along the floor. A roller is supported on the frame for rotational motion relative thereto. The roller has an axis of rotation disposed substantially parallel to the floor when the apparatus is in use. A drive assembly is operatively connected to the roller for rotatively driving same. Gripping means in the nature of a plurality of gripping members, are carried on the roller for grippingly engaging a portion of the flexible floor covering. The apparatus further includes a grip releasing means for urging the gripping means to disengage from the portion of the flexible floor covering after the flexible floor covering has been detached from the floor. The grip releasing means is mounted to the frame and disposed adjacent the roller. The grip releasing means is operable to discourage the portion of the flexible floor covering from being wound about the roller. In operation, the gripping members grippingly engage the portion of flexible floor covering and cause it to detach from the floor as the roller rotates about its rotational axis. The grip release means meets the gripping members and functions as a wedge placed between the portion of flexible floor covering and the gripping members thereby causing the portion of flexible floor covering to physically separate from the gripping members.

Abstract: L'invention porte sur une nouvelle classe de complexes de ruthénium (II) contenant comme ligands des 2-(aminométhyl)pyridines et des phosphines, s'étant avérés extrêmement actifs comme catalyseurs dans la réduction des cétones en alcools par transfert d'hydrogène. En utilisant du 2-propanol comme source d'hydrogène, avec lesdits complexes de ruthénium, on peut obtenir rapidement de forts rendements de l'alcool correspondant en partant des alkyl aryl, dialkyl et diaryl cétones linéaires et cycliques. La conversion des cétones en alcools peut atteindre 100 % lorsqu'on opère dans une atmosphère d'hydrogène sous (2 - 3 atm). Si les phosphines utilisées sont optiquement actives, on peut, en partant de composés cétoniques prochiraux, obtenir différents types d'alcools optiquement actifs, importants intermédiaires dans l'industrie pharmaceutique, dans l'industrie agrochimique et d'une manière générale dans la production de produits chimiques fins.
