Abstract: A microscope stage is movably mounted to a base and is movable relative to the base by two separate drive units on separate rail systems situated at an angle relative to one another. The drive units are mechanically isolated from one another and one of the drive units uses a belt drive.

Abstract: The invention relates to a device (10) for moving a microscope (100) stage, which device (10) has a first and second rail system (16a, 16b), and has a microscope stage (12) that may be moveably fixed to a first base (14) with the first and second rail systems (16a, 16b), furthermore, it contains: —a first drive unit (20a) for moving the stage (12) along the first rail system (16a), connected to the stage (12) via a first drive connection, and —a second drive unit (20b) for moving the stage (12) along a second rail system (16b) positioned at an angle to the first rail system (16a), connected to the stage (12) via a second drive connection, the essence of which is that the first drive unit (20a) is arranged on a second base (15) that is mechanically isolated from the first base (14), and the first drive connection is provided as a belt drive.

Abstract: The installed fire fighting apparatus has one or more forwarding pipelines to transfer a fire extinguishing substance composition to a place of use, and one or more spreading devices connected to the output end of the forwarding pipeline, serving for directed discharge of the fire extinguishing substance composition and designed to be fixed to a flammable object. The apparatus includes a storage pipeline to store the fire fighting substance composition, comprising a pipeline with a cross-section exceeding the cross-section of the forwarding pipeline and closed at its ends or closed into itself like a loop, where the storage pipeline is equipped with a feeder pipe end with a pressure-tight shut-off device, a valve on the feeder pipe end, as well as a device to measure pressure in the interior space of the storage pipeline and a safety fitting, preferably a safety valve. The storage pipeline has a forwarding branch-off, to which branch-off the forwarding pipeline is connected by its input end.

Abstract: The fire fighting apparatus is equipped with a tank containing an extinguishing agent, a pipeline to forward the extinguishing agent, and a device to spread the extinguishing agent, particularly a nozzle. The tank (10) is located in a lower space of the building; the pipeline to forward the extinguishing agent is ascending pipeline (15) fixed along the height of the building; there are pipe sections branching off the ascending pipeline (15) at specific heights; and there are local shut-off devices and tools to spread the extinguishing agent at the end of each pipe section. The tank (10) is equipped with a gas space and the extinguishing agent inside it is a foam composition comprising water, a foaming agent, and in the solution of these two, a non-combustible foaming and propellant gas diluted or emulgeated under overpressure.

Abstract: Method for producing fire fighting foam using a composition is prepared consisting of foaming agent, water and gaseous medium. The composition is prepared via dissolving or emulsifying the components in one another under overpressure, the composition prepared this way is stored under overpressure at the required place for the required period of time, transported if necessary maintaining the overpressure, and it is expanded via decompressing it on the spot and at the time of application. The apparatus for producing the fire fighting foam comprises a high-pressure foam source (10), a foam expanding spreading device (60) and a pressure resistant pipeline (40) connecting the high-pressure foam source (10) with the foam expanding spreading device (60).

Abstract: The invention relates to an apparatus for impulse fire extinguishing which includes an ejection tube for storing fire fighting powder or liquid and a container for storing gaseous propellant. The container is connected to the ejection tube. A quick action closing element is located between the container and the ejection tube and is arranged in the container to move freely therein for separating the container into two parts: a propellant chamber and an equalizing chamber. The ejection end of the ejection tube extends into the atmosphere, and the input end thereof is arranged in the propellant chamber in a way that it is open in a first position of the quick action closing element and closed in another position thereof.

Abstract: A process and apparatus for the fine dispersion of liquid or powder in a gaseous medium, preferably in air. The liquid or powder is placed into an ejection tube (2) and pressurized gaseous propellant (4) is conducted at explosion-like speed behind the charge (1). The apparatus has an ejection tube (2) containing the liquid or powder charge (1), a propellant container (3) connected with one end of the ejection tube (2). The ejection tube (2) and propellant container (3) are interconnected by at least one transfer port (8) closed by a quick-action locking element.
