Abstract: A liquid dispenser for dispensing a cosmetic or pharmaceutical liquid produced by mixing two starting liquids. The liquid dispenser has at least two liquid reservoirs for holding the two starting liquids and a discharge opening, and at least one pump device by which liquid can be delivered from the liquid reservoirs to the discharge opening. The dispenser has one intake opening for removing the liquid, via the at least one pump device, at one end of each liquid reservoir, and one intake tube extending from the intake opening to a bottom end of each liquid reservoir. Further, one filling opening is provided at the bottom end of each of the liquid reservoirs.

Abstract: A length compensator for pipelines, preferably plastic pipelines, containing two connecting components, preferably made from plastic, a compensating element made from an elastic material, preferably a thermoplastic elastomer (TPE), and a supporting pipe, wherein the compensating element is arranged between the two connecting components and the compensating element ends are connected to the connecting components, wherein the outer lateral surface of the compensating element is suitably encompassed by the inner lateral surface of the supporting pipe around its entire circumference, wherein the supporting pipe has a circular cross-sectional area and the compensating element expands and contracts exclusively in the axial direction.
