Patent number: 7764505Abstract: The invention relates to a joint which can be subjected to the temperature influences of an external medium (20) and joins an especially ceramic component (2) to an especially metallic component (1). Said joint consists of a first adhesive joint (14) between the metallic component and the ceramic component, and a second adhesive joint (22), the adhesive (16) of the second joint having a higher elasticity than that (10) of the first adhesive joint (14), and the second joint being arranged in such a way that it prevents direct contact between the first adhesive joint (14) and an external medium (20). The inventive joint can preferably be used, for example, preferably in a sensor module of a measuring appliance which can be introduced into a medium to be analyzed.Type: GrantFiled: December 17, 2003Date of Patent: July 27, 2010Assignee: Testo AGInventors: Mike Muhl, Andreas Derr, Gerd Heckelmann, Heinz Oswald, Jürgen Hall

Patent number: 4817896Abstract: A chuck is adapted to be cantilever-mounted for rotation about a longitudinal axis thereof in a winding machine for threads, such as synthetic plastics filament, glass fiber strands and so forth. The chuck comprises a chuck member and an element movable radially thereat between retracted and extended positions under the action of centrifugal force when the chuck is rotated about its longitudinal axis at or above a predeterminate operating speed in use. The element has a head portion which projects radially outwardly from the bobbin tube receiving surface of the chuck member of the chuck when the element is in its extended position, and is located inwardly of such bobbin tube receiving surface when the element is in its retracted position.Type: GrantFiled: January 28, 1987Date of Patent: April 4, 1989Assignee: Rieter Machine Works Ltd.Inventors: Peter Busenhart, Heinz Oswald, Ruedi Schneeberger

Patent number: 4762284Abstract: A machine for winding thread comprising an operating region in which thread packages are formed and retained, if necessary, to await doffing thereof. At least one chuck is provided in the operating region, which is rotatable about a longitudinal chuck axis for winding of thread into a package thereon and has a predetermined doffing position in the operating region. An enclosure having at least one access door is provided for the operating region, the door being movable relative to the enclosure for exposing an access opening to said doffing position while the enclosure hinders access to other portions of the operating region.Type: GrantFiled: June 27, 1986Date of Patent: August 9, 1988Assignee: Maschinenfabrik Rieter AGInventors: Adolf Flueli, Kurt Schefer, Heinz Oswald

Patent number: 4741485Abstract: The winder is provided with thread divertor guides for both the upper and lower chucks with the angle of diversion not exceeding 120.degree.. The geometry of the winder is such that the respective chucks contact the contact member in separate sub-zones of the winding zone which are spaced apart by a narrow gap. The included angle between the imaginary lines joining the axis of each chuck in its respective rest position to the axis of the chuck when in contact with the contact member lies in a range of from 60.degree. to 175.degree.. The contact member when in the form of a friction drive roll has an external diameter of from 100 to 155 millimeters. When the contact member is in the form of a contact roll with each chuck having an independent drive, the roll may have a diameter in the range of from 60 to 80 millimeters.Type: GrantFiled: December 15, 1986Date of Patent: May 3, 1988Assignee: Rieter Machine Works, Ltd.Inventors: Adolf Flueli, Claudio Molteni, Jurg Neff, Heinz Oswald, Beat Ruf, Kurt Schefer

Patent number: 4739940Abstract: The method of forming an overwound thread transfer tail entails moving a thread guide carrier which supports a thread guide in a first direction against an abutment and permitting the thread guide carrier to recoil and thereby cause a return movement of the thread guide after striking said abutment. The apparatus for performing the method comprises a thread guide and a movable member movable in a predetermined direction and connected to the thread guide. An abutment serves for limiting movement of said movable member in such predetermined direction, and structure is provided for moving the movable member against the abutment in a manner such as to cause recoil of the movable member.Type: GrantFiled: November 3, 1986Date of Patent: April 26, 1988Assignee: Rieter Machine Works LimitedInventors: Adolf Flueli, Heinz Oswald, Kurt Schefer

Patent number: 4739694Abstract: The thread winding machine includes a piston and cylinder unit, comprising a cylinder housing with first and second chambers and a dividing structure between said first and second chambers. A piston is movable longitudinally in the first chamber and a piston extension projects from said piston towards the second chamber. A port in the dividing structure receives the piston extension when the piston is near the dividing structure, thereby separating said first and second chambers. A thread guide is connected to the piston of the piston and cylinder unit for movement in combination therewith.Type: GrantFiled: November 3, 1986Date of Patent: April 26, 1988Assignee: Rieter Machine Works Ltd.Inventors: Adolf Flueli, Heinz Oswald, Kurt Schefer

Patent number: 4641793Abstract: The thread winding machine comprises a rotatable chuck having a thread catching device adjacent to a location for a bobbin tube upon the chuck. A thread guide engages the thread and moves it axially of the chuck into the catching device at a first speed and then onto the bobbin tube location at a second, higher speed. An overwound thread reserve or transfer tail is formed by moving the thread guide against a resilient damper, causing it to stop and rebound.Type: GrantFiled: April 16, 1985Date of Patent: February 10, 1987Assignee: Rieter Machine Works LimitedInventors: Adolf Flueli, Heinz Oswald, Kurt Schefer

Patent number: 4524918Abstract: A filament winder of the automatic exchange type in which chucks are brought successively into winding positions relative to a friction drive roller and thread is transferred from a package on an outgoing chuck to a bobbin on an incomming chuck. Each chuck moves along its own predetermined path towards and away from the friction drive roller. A free thread length is created between the friction drive roller and the outgoing chuck and this free thread length is intercepted by thread catching means on the incoming chuck.Type: GrantFiled: August 26, 1982Date of Patent: June 25, 1985Assignee: Rieter Machine Works, Ltd.Inventors: Markus Feusi, Josef Huber, Heinz Oswald, Peter Pfyffer

Patent number: 4482099Abstract: The thread catching and severing ring structure includes a ring element which is press fit onto a second ring element. The first ring element has a plurality of projections which overlie a groove on the second ring element. The projections and groove are sized so that a thread can be guided into the groove and thereafter into a gap between a land on the second ring element and a projection on the first ring element.Type: GrantFiled: June 3, 1983Date of Patent: November 13, 1984Assignee: Rieter Machine Works Ltd.Inventors: Heinz Oswald, Walter Vetterli

Patent number: 4477034Abstract: The thread catching structure is mounted on a chuck and includes a winding-on surface from which a thread winding may extend into a shaped recess under an overlying projection. The thread catching structure also has a clamping element which presses outwardly under centrifugal force against an underside of the projection to clamp the thread therebetween. Upon a subsequent severing of the thread, the resulting thread tail extending to the break location remains firmly clamped.Type: GrantFiled: August 15, 1983Date of Patent: October 16, 1984Assignee: Rieter Machine Works, Ltd.Inventor: Heinz Oswald

Patent number: 4106711Abstract: A chuck device for a tube used for supporting thread packages of textile yarns or threads comprisng a thread severing ring provided with protruding substantially tooth-shaped cutting elements and an adjacent thread guide ring which, for the purpose of guiding the thread in a direction towards the thread severing ring, is provided with a thread guide surface extending beneath the cutting elements and an adjacent extension or projection. The extension has recess means and radially movable clamping means are arranged in the recess means. At the operational rotational speed of the chuck the radially movable clamping means in conjunction with the cutting elements form clamping points or locations for the thread caught therebetween.Type: GrantFiled: November 10, 1977Date of Patent: August 15, 1978Assignee: Rieter Machine Works Ltd.Inventors: Heinz Oswald, Olivier Wust
