Patent number: 8625212Abstract: A system for guiding optical elements, in particular lenses, along an optical axis of a microscope, in particular a stereomicroscope, or of a macroscope, guide system including at least one guide rod which extends parallel to the optical axis and is at least partially made from a magnetizable material, and further including a carrier for the optical elements, the carrier being displaceable along the at least one guide rod and providing magnetic attraction between itself and at least one guide rod; for providing magnetic attraction, including at least one magnetizable wheel adapted to roll along the at least one guide rod while rotating about an axis as the carrier is displaced; the at least one guide rod (312, 314) being made of magnetizable material and/or the magnetizable wheel being at least in part permanently magnetic.Type: GrantFiled: February 11, 2011Date of Patent: January 7, 2014Assignee: Leica Microsystems (Schweiz) AGInventor: Didier Henry

Patent number: 8424844Abstract: An apparatus for adjusting a tension of a pulling device in a pulling-device drive includes a body and a lever arm. The pulling-device drive includes first and second shafts and the pulling device loops around the first and second shafts. The body includes a receptacle adapted to interact with the first shaft and a support point adapted to rotatably dispose the body about an axis of rotation. The lever arm extends from the body so that a spacing between the first and second shafts is modifiable by action of a force on the lever arm.Type: GrantFiled: February 17, 2009Date of Patent: April 23, 2013Assignee: Leica Instruments (Singapore) Pte. Ltd.Inventor: Didier Henry

Patent number: 7762527Abstract: A vacuum valve comprises a valve body with a valve opening, a valve plate which is adjustable from an open position, in which it releases the valve opening, to an intermediate position, in which it covers the valve opening but is lifted from the valve seat, into a closed position in which it contacts the valve seat, and from the closed position to the intermediate position into the open position, a valve rod carrying the valve plate, a transverse drive unit by which the valve plate can be displaced in a transverse adjusting direction extending transverse to the longitudinal axis of the valve opening, a longitudinal drive unit by which the valve plate can be displaced in a longitudinal adjusting direction extending parallel to the longitudinal axis of the valve opening and opposite the longitudinal adjusting direction, and a guide device by which the transverse drive unit is guided so as to be displaceable relative to the valve body parallel to the longitudinal adjusting direction.Type: GrantFiled: July 17, 2007Date of Patent: July 27, 2010Assignee: VAT Holding AGInventors: Mathias Schoen, Didier Henry
