Patent number: 8403188Abstract: A dosing device for powder has an inlet and an outlet for powder. A dosing disc rotatable from inlet to outlet has a dosing area of sintered material, which is provided with cavities for the volumetric dosing of the powder. A dosing body having open dosing cavities is provided which is movable from the inlet and outlet. By changing the speed of rotation of the dosing disc the quantity of powder to be discharged can be set in a wide range.Type: GrantFiled: March 13, 2008Date of Patent: March 26, 2013Assignee: Platsch GmbH & Co. KGInventor: Hans G. Platsch

Publication number: 20090162148Abstract: A feed device for conveying a powdery medium from a powder container into a powder conduit is specified and has a powder channel which connects the powder container and the powder conduit. The powder channel also, in a working position, is arranged with a vertical component of the axis of the powder channel above a charge end of the powder conduit. The powder channel has a joint unit with a charge joint part, to which the powder container is connected detachably in a sealed manner, and a delivery joint part for connecting the powder channel in a sealed manner to the charge end of the powder conduit. Displacement travel of the joint unit is sufficiently large for a filling level of the powder container to be located below an opening of the powder container in a lowered exchange position.Type: ApplicationFiled: May 20, 2008Publication date: June 25, 2009Applicant: Platsch GmbH & Co. KGInventor: Hans G. Platsch
