Patent number: 10786790Abstract: The present invention relates to a static mixer for mixing together at least two components. The static mixer comprises a mixer housing; a mixing element having an upstream end with at least two entry openings and a downstream end, the mixing element being arranged at least partly within the mixer housing; a mixing head having at least two inlets provided at an input side and at least two outlets provided at an output surface, wherein each of the at least two inlets is in fluid communication with one of the at least two outlets; and a separating wall disposed between the output surface and the upstream end of the mixing element for separating the components leaving the outlets. The separating wall comprises a free downstream edge which is disposed with respect to at least one of the entry openings so as to allow at least partial flows of the components separated by the separating wall to combine after exceeding the downstream edge and to jointly enter said at least one of the entry openings.Type: GrantFiled: October 28, 2016Date of Patent: September 29, 2020Assignee: SULZER MIXPAC AGInventors: Andreas Hiemer, Joachim Schöck, Percy Leue

Patent number: 9707053Abstract: A dispensing apparatus for a flowable component includes a storage container having a storage chamber for the reception of the component, a filling opening and a dispensing opening. A piston is displaceably arranged within the storage container in the direction of an expulsion direction. Moreover, dispensing apparatus includes an actuation element by which the piston can be displaced stepwise in the direction of the dispensing opening. After release of the actuation element actuation element is displaced from a final position into a starting position by a spring.Type: GrantFiled: December 22, 2016Date of Patent: July 18, 2017Assignee: SULZER MIXPAC AGInventor: Percy Leue

Patent number: 9616454Abstract: A multicomponent cartridge which is designed for single use includes two separate supply chambers arranged coaxially of each other and two pistons. The two pistons are movable via a plunger to simultaneously discharge two components. A guide element guides the two pistons in the respective supply chambers and contains a discharge opening for discharging the first component. The guide element is movable relative to a housing via a movement element in order to open the discharge opening.Type: GrantFiled: February 9, 2010Date of Patent: April 11, 2017Assignee: SULZER MIXPAC AGInventors: Andreas Staub, Percy Leue

Patent number: 9617062Abstract: A dispensing apparatus includes a storage container having an outlet flange with a component outlet which is at least partly surrounded by an inlet flange. The inlet flange is configured to adopt a closed position and a dispensing position with respect to the outlet flange. A change from the closed position into the dispensing position is carried out by a rotation of the inlet flange with respect to the outlet flange. The component outlet is arranged at a cylindrical jacket surface of the outlet flange. The first component outlet is closed by the inlet flange in the closed position of the inlet flange. In the dispensing position, a connection is established by a crossover passage between the first component outlet and a dispensing opening.Type: GrantFiled: August 20, 2013Date of Patent: April 11, 2017Assignee: SULZER MIXPAC AGInventor: Percy Leue

Patent number: 8899412Abstract: A multicomponent cartridge designed for single use includes a first storage chamber for a first component and a second storage chamber for a second component. The first storage chamber being separate from the second storage chamber. The first storage chamber is arranged coaxially around the second storage chamber and forms a ring space, with a first piston being movably received in the first storage chamber and a second piston being movably received in the second storage chamber. The first and second pistons are movable by means of a plunger to dispense the two components simultaneously. The plunger is held in a housing element (and a guide element is provided to guide the first piston in the first storage chamber and to guide the second piston in the second storage chamber, with the housing element including an engagement element which can be brought into engagement with the guide element.Type: GrantFiled: May 10, 2010Date of Patent: December 2, 2014Assignee: Sulzer Mixpac AGInventor: Percy Leue

Patent number: 8651731Abstract: The invention relates to a dynamic mixer for viscose components in particular for the mixing of dental compositions, with a rotor (30) and a housing (2), which has front inlet openings (12, 13) for the components and at least one rear outlet opening (20) and the inner space of which includes a pre-chamber (17) and a main chamber (22), with the pre-chamber (17) opening into the main chamber (22) in a distal, tapering transition section (16). For the precise regulation of the concentration of the components to be mixed of the supplied components even with temporary concentration fluctuations of the same and in order to achieve a high degree of homogenization, it is proposed that the dynamic mixer (1) has at least one individual channel (23a-d) as a passage from the pre-chamber (17) into the main chamber (22), with the width of the individual channel (23a-d) extending over a part of the periphery of the transition section (16).Type: GrantFiled: June 6, 2008Date of Patent: February 18, 2014Assignee: Sulzer Mixpac AGInventors: Torsten Wintergerste, Hubert Holdener, Percy Leue
