Abstract: The invention relates to a method for rendering ultrasonic signals audible that is characterized in that the temporal dynamic range of the ultrasonic signal is maintained. The amplitude profile of the ultrasonic signal picked up in the time domain remains unaltered. The frequency shift from the ultrasonic range to the audible range is possible up to a factor of 32 using the present invention.

Abstract: A nozzle device for a spray arm of a dishwasher for spraying cleaning fluid out into a dishwashing space is provided with a fluid outflow surface for the outflow of the cleaning fluid from the nozzle device into the dishwashing space. The fluid outflow surface is configured with two subsurfaces which form an angle smaller than 180°.

Abstract: A water switch of a water-bearing appliance, in particular a domestic appliance, including at least one water supply path, several water discharge paths and an adjustable water distribution element, the water distribution element having at least one passage opening and being rotatable around an axis from a first angular position to a second angular position, in the first angular position the at least one passage opening connecting the at least one water supply path to a first water discharge path, and in the second angular position the at least one passage opening connecting the at least one water supply path to a second water discharge path, is characterized in that a guiding mechanism is provided for guiding an axial movement along the axis of the water distribution element when the water distribution element rotates from the first angular position to the second angular position.

Abstract: A chain tensioning device for use in a motor vehicle with a cylinder-piston unit (10) that has a piston housing (11) and a tensioning piston (12) that is provided for tensioning a chain and is arranged at least partially in the piston housing (11). A chain tensioner housing (13) is provided for establishing a flow connection between the cylinder-piston unit (10) and an operating medium circuit and holds at least partially the cylinder-piston unit (10). A compression joint fixes the piston housing (11) and the chain tensioner housing (13) against each other at least in the axial direction. The compression joint is constructed as a press fit by which the piston housing (11) and the chain tensioner housing (13) are directly connected to each other with a friction fit.
