The invention relates to a milk-frothing apparatus, in particular for a coffee or espresso machine, comprising a froth-generating unit (22) which is in the form of a disposable part, which is easy to replace, and has a mixing chamber (40), an outlet (39), which leads to the outside from the mixing chamber (40), for the generated milk froth, and first means (42) through which the froth-generating unit (22) is supplied with steam and air (53), and also second means (43) through which the froth-generating unit (22) is supplied with milk, wherein the froth-generating unit (22) can be connected to a holding means (30) in a detachable manner. The froth-generating unit (22) can be replaced in a simple and reliable manner while at the same time operating in a flexible manner by the first means comprising a first inlet (42) through which steam and air enter the froth-generating unit (22) together, by a combined steam/air nozzle (33), which projects outward and is connected to a steam generator and an air pump and through which steam and air are routed together, being provided on the holding means (30), and by the first inlet (42) and the steam/air nozzle (33) being designed and matched to one another such that they form a detachable hydraulic plug connection.

The invention relates to a particularly reliable sliding door construction for platforms, by means of which a passenger area of platforms may be separated from a track area when closed, preventing entry to an arriving train and permitting access to the arriving train in an open state, comprising stationary regions and sliding doors, both the stationary regions and the sliding doors having a height of 1-2 m above the floor level of the passenger region above which no separation of passenger region and track region is arranged. The construction is characterized in that the sliding doors have a self-supporting embodiment and are guided to move in or on the stationary regions with provision of an upper and lower guide and one guide is embodied as a roller guide or ball bearing linear guide and one guide is embodied as a slide guide or roller guide.

A membrane for a cover for closing a container having the general form of a cylinder and being compressible in the direction of the axis of the cylinder. The membrane comprises two mutually parallel, generally flat parts arranged to move axially in relation to each other guided in the movement by guiding elements; resilient element arranged to generate a counterforce between the flat parts during compression of the membrane in the direction of the axis; at least a first and a second electrical contact device operated by the axial movement between the circular parts, the combined electrical settings of which contact devices will carry information about the compressions and decompressions of the membrane and elements for presenting the settings to the outside of the membrane. A cover comprising such a membrane and use thereof are also described.
