Abstract: The invention relates to a device for suctioning gaseous or liquid media, which arise preferably in medical care, for example in medical aids, and are suctioned out of said medical aids noiselessly by means of a vertically extendable bellows (4), the bellows upper end (5) of which is fastened to an upright (1, 3) and the bellows lower end (6) of which is connected to a slidably guided loading part (2), which produces a vacuum in the interior (14) of the bellows (4) as the loading part drops under gravitational force, which vacuum forces a suctioning of the medium from the aid into the bellows (4), wherein the bellows (4) unfolds.

Abstract: The invention relates to a device comprising an absorption article, and an air-extraction device for humid conditions prevailing in the region of the absorption article, for example a diaper, when worn by a person, and also comprising a flexible container, which is arranged in the humid region of the person's body, is provided with apertures in its wall and has air exchanged by way of a pump. A method of operation for improving the conditions in the absorption article by having air extracted by suction from the absorption article using the air-extraction device is also described.

Abstract: The construction has been created such that the hot water is flowing from a closed secured container without danger of scalding and dripping over to the drinking cup, which is also secured.

Abstract: The device for heating a drinkable liquid, having a liquid-storage container (9) and an electric heating element (11) arranged therein, the liquid-storage container (9) having a valve which is arranged at the bottom in the base (12) of the liquid-storage container (9) and of which one sealing surface is the border of an opening (14) in the base (12) and which opens, in a manner which cannot automatically be reversed, on account of the base curving outwards at a predetermined internal pressure in the container, and the power supply to the heating element (11) being designed such that it is interrupted when the pressure in the liquid-storage container (9) is essentially equal to the atmospheric pressure, which device can be positioned on a collecting container for the liquid, is distinguished in that the other sealing surface of the valve is a plate-like element (15) which consists of elastic material and, in its non-loaded state, is shaped essentially conically, with the cone tip directed towards the interior

Abstract: The container which can be inserted into a power-supply unit (17, 18) and is intended for the preparation of hot drinks, with a liquid-storage container (4), an electric heating element (7) arranged therein and a collecting container (1) for the drink prepared, the liquid-storage container (4) having a closure (9, 10) which is arranged in the bottom (8) of the liquid-storage container (4) and opens in a manner not automatically reversible at a predetermined internal pressure of the container, due to the arching outwards of the bottom (8), which is provided with contacts (6) for the supply of electrical power and which can be inserted or is inserted into the collecting container (1) in such a way that, in the operating position, the collecting space is essentially below the storage container (4), and the power supply to the heating element (7) being designed in such a way that it is interrupted when the closure (9, 10) is opened, is distinguished by the fact that the closure (9, 10) is formed by an annular pro

Abstract: A device for preparing hot drinks is disclosed having a liquid-storage vessel 3, an electric heating element 14 arranged therein, a current supply circuit 17 and a collecting vessel 1 for the prepared drink. This device can be used very advantageously, particularly in vehicles. It is characterized in that the storage vessel 3 is designed as a unit separate from the current supply circuit 17 and closed by valve 10-13 which opens irreversibly at a predetermined pressure inside the storage vessel 3, and is provided with contacts 16 for the supply of electrical current which are connected to the heating element 14 via an electric line 15 which is interrupted when the valve 10-13 is opened. The storage vessel 3 is insertable into the collecting vessel 1 in such a way that in an operative position of the storage vessel 3, a collecting space of the collecting vessel 1 is situated essentially below the storage vessel 3.
