    • An applicator for highly viscous materials such as dental filling materials has a housing and a first and second jamming element positioned spaced from one another in a longitudinal direction in the housing. A coupling rod is connected to the second jamming element. A piston rod is supported in the housing. An actuating element is positioned at the housing and connected to the piston rod for moving the piston rod in a forward direction from an inactive position into a working position, and in a rearward direction from the working position into the inactive position. The first jamming element is jammed, when the actuating element actuates the piston rod in the forward direction, and is moved with the piston rod in the forward direction. The second jamming element is jammed by a spring force in the rearward direction so as to rest at the housing, when the actuating element actuates the piston rod in the forward direction. The actuating element, when moving the piston rod in the rearward direction, acts on the coupling rod for releasing the second jamming element.
    • 用于高粘度材料(例如牙科填充材料)的施加器具有壳体和在壳体中沿纵向方向彼此间隔开的第一和第二干扰元件。 连接杆连接到第二干扰元件。 活塞杆支撑在壳体中。 致动元件定位在壳体处并连接到活塞杆,用于将活塞杆从非活动位置向前方移动到工作位置,并且在从工作位置向无效位置的向后方向上移动。 当致动元件向前方向致动活塞杆时,第一个卡住元件卡住,并且随着活塞杆向前移动。 当致动元件沿向前方向致动活塞杆时,第二阻塞元件在向后方向上被弹簧力卡住,以便搁置在壳体上。 当将活塞杆沿向后方向移动时,致动元件作用在联接杆上以释放第二干扰元件。

    • A hand-held light curing device has a light source and a light guiding device having a light receiving opening. A lens arrangement with a focusing lens is positioned between the light source and the light guiding device. The focusing lens has first and second cut-off filters on proximal and distal surfaces thereof, respectively. The cut-off filters are preferably vapor-deposited on the surfaces. Preferably, the focusing lens has a convex surface facing the light source, and the first filter has reflective properties with respect to infrared light.
    • 手持式光固化装置具有光源和具有受光开口的导光装置。 具有聚焦透镜的透镜装置位于光源和导光装置之间。 聚焦透镜分别在其近端和远端表面上具有第一和第二截止滤光片。 截止过滤器优选在表面上气相沉积。 优选地,聚焦透镜具有面向光源的凸面,并且第一滤光器相对于红外光具有反射特性。
