20090145921 | Method and Device for Producing a Multicomponent Compound - The method and the device for producing a multicomponent compound, in particular for dental purposes, is characterized in that the pressing-out process, at the beginning thereof, is carried out at a reduced pressure. | 06-11-2009 |
20090266839 | Method and Device for Producing a Multicomponent Compound - The method and the device for producing a multicomponent compound, in particular for dental purposes, is characterized in that the drives of the pistons of cartridges are initially moved with a higher speed until air pockets in the cartridges are eliminated and said cartridges are filled only with the component, and in that the feed speed is then reduced to constant values with which the components can be pressed out. | 10-29-2009 |
20100091607 | DEVICE FOR PRODUCING A MULTI-COMPONENT COMPOUND - A device for producing a multi-component compound, in particular for dental purposes, by mixing its components after they have been pressed out of cartridges which open into a dynamic mixer and are arranged exchangeably in the device, with a first motor for advancing all of the pistons assigned to the cartridges, and with a second motor for rotary driving of mixing elements in the mixer via a shaft, which is held in engagement with the mixer by spring pretensioning and can be pulled back from the mixer counter to the spring pretensioning, is characterized in that the shaft is provided with a radially extending projection which, by means of the spring pretensioning, is pressed onto a ramp-like upwardly sloping cam surface, which is provided on its foot with an abutment surface, of a toothed wheel, which is provided with saw-like teeth and is coaxial to the shaft, which toothed wheel, in a first angle direction in which the cam surface slopes upwards, is prevented from rotating by a catch and, in the second angle position opposite thereto, is rotatable, the mixer drive shaft being pulled back during rotation in the first direction of rotation. | 04-15-2010 |
