Abstract: A personal care system includes an electrical shaver and a cleaning device for cleaning a shaving head. The cleaning device further includes a displacing system for displacing its supporting member relative to a cleaning fluid container from a first position in which the shaving head, when the shaver is supported by the supporting member, is not in contact with the cleaning liquid in the container, to a second position in which the shaving head is at least partially immersed in the cleaning liquid in the container. The cleaning device does not need any pump for displacing the cleaning liquid. Rather, activation of the shaving head that causes, e.g., rotation of a cutting unit, provides a sufficient pumping effect for the cleaning liquid when the shaving head is immersed in the cleaning liquid.

Abstract: The invention relates to a personal care system (1) comprising an electrical shaver (3) and a cleaning device (5) for cleaning a shaving head (7) of the shaver (3). The cleaning device comprises a container (11) for a cleaning liquid (13) and a supporting member (15) for the shaver. According to the invention the cleaning device comprises a displacing system (17) for displacing the supporting member relative to the container from a first position in which the shaving head, when in operation the shaver is supported by the supporting member, is not in contact with the cleaning liquid in the container, to a second position in which the shaving head, when in operation the shaver is supported by the supporting member, is at least partially immersed in the cleaning liquid in the container.

Abstract: An expansion tank to be connected to a pipe system filled or with a liquid is disclosed. The expansion tank includes at least one connection opening for a liquid pipe. The tank has a main valve to close off the connection opening at a defined difference in pressure between the interior of the tank and the connection opening and/or at a defined liquid level in the tank. The tank also has an additional valve for closing off a channel extending through the closure member of the main valve from the interior of the tank to the connection opening. The additional valve is closed during normal operation of the expansion tank and is open if the difference in pressure between the interior of the tank and the connection opening is higher than the original pressure in the expansion tank.

Abstract: An expansion tank (1) which is intended to be connected to a pipe system which is filled or is to be filled with liquid, comprises a substantially closed tank (2) having at least a first connection opening (6) for connection to a liquid pipe, a second connection opening for connection to a source of pressurized gas (14), and an element (8) which can move inside the tank and is designed to move with the interface (11) between liquid (9) and gas (10) in the tank. The tank is provided, at the location of the second connection opening, with a valve assembly (7) which can open and close the second connection opening and can be actuated by the movable element (8) in the tank.

Abstract: An operating assembly comprises a support structure (9), a user-operable operating member (7) movable in at least one direction of movement (10, 11) relative to the support structure (9) between a plurality of positions supported by the support structure (9); an array (14) of catches (15) extending along the direction of movement (10, 11); and a clicking pawl (16) resiliently accommodated for consecutive engagement with and disengagement from consecutive ones of the catches (15) of the array (14) in response to a movement of the operating member (7) in the direction of movement (10, 11). At least the clicking pawl (16) or the array (14) of catches (15) is accommodated with clearance (32) in the direction of movement (10, 11). A device comprising such an operating assembly is also described.

Abstract: An expansion tank which is intended to be connected to a pipe system which is filled or is to be filled with a liquid, comprises a closed tank with at least one connection opening for a liquid pipe. The tank is provided with a main valve inside the tank having a valve seat and a closure member and being designed to close off the connection opening at a defined difference between the pressure in the interior of the tank and the pressure in the connection opening and/or at a defined liquid level in the tank. The tank is further provided with an additional valve for closing off a channel or passage extending through the closure member of the main valve from the interior of the tank to the connection opening.

Abstract: A battery-powered apparatus is provided having a battery (B1), detection means (IC1) for detecting a discharge condition of the battery, and signaling means (D) for indicating the discharge condition of the battery, as well as discharge means (R5, T1) which are activated by the detection means when a predetermined first discharge condition of the battery is reached, in order to discharge the battery in a controlled manner until a predetermined second discharge condition of the battery has been reached.
