Abstract: A pumping system for an oral composition, having selected rheological properties, useful in oral treatment. The pumping system has defined rheological characteristics to move such an oral composition from a reservoir to an outlet of the system at a given rate.

Abstract: A carrying arrangement for a hand-guided power tool has a carrying element to be guided across a shoulder of an operator and a shoulder support arranged slidably in a longitudinal direction on the carrying element. A friction-reducing element for reducing friction between the carrying element and the shoulder support is provided. The shoulder support has a shoulder section and a lateral support section connected to the shoulder section. The carrying element is arranged on the shoulder section and the lateral support section rests against a side of the operator. In this way, excellent force distribution during operation is ensured.

Abstract: A carrying system for an implement, comprising a carrying arm and a receiving device held on the carrying arm for receiving the guide rod of the implement. In a first state, the receiving device is adapted to fix the guide rod in a longitudinal direction thereof. In a second state, the receiving device is displaceable in the longitudinal direction of the guide rod.
