A method for measuring, in particular simultaneously measuring, different particle concentrations, in particular particulate matter concentrations, preferably in a flow, using a particle measuring system, in particular a particulate matter measuring system, comprising a photometric scattered light unit () with a measurement volume (), wherein the scattered light unit () consists of at least one light transmitter () which emits () light signals, in particular pulsed light signals, and of at least one light-sensitive receiver system (), which is arranged at at least one angle () and which receives the scattered light () from the particles () forming the particle concentration, characterized in that the scattered light unit () with measurement volume () is hermetically sealed with the exception of at least one fluid inlet () and/or at least one fluid outlet (), which are provided with blocking devices (), wherein a sample of the fluid to be examined is applied to the scattered light unit () with measurement volume () and a predeterminable first number of measurement values is recorded.

A light construction panel having excellent outer appearance and high persistent against deformation is disclosed. The light construction panel is formed with an outer frame and a core, the frame and the core having the same material thickness, and also with an upper and a lower cover sheet which cover the frame and the core. The core consists of an inner part made from light construction material and an upper and lower sealing layer. Such a panel is distinguished by a particular rigidity. Moreover the transition between frame and core no longer shows on the surface of the panel.

A table with an interface for the connection of a data processing system includes a reading device integrated in the table which cooperates with a transponder. The reading device contains a circuit component for detecting a modulation of an electromagnetic field caused by the transponder as well as a circuit component for generating a signal corresponding to the modulation and transmitting the signal to the interface of the furniture system.

A table with a pivotable table top for changing between a working position and a stacking position. The table has a table top and a table frame, wherein the table frame has a horizontal beam, at least one support part for supporting the table top and one or more table legs fixedly coupled to the support part, wherein the table top is hinged to the table frame so as to be pivotable about a horizontal pivot axis, and wherein the support part is movable transversely with respect to the pivot axis between the working position and the stacking position or is coupled to the beam so as to be pivotable about a vertical axis. Between the table top and the support part coupling means are provided which effect common pivoting or turning of the table top and of the table leg coupled to the support part.

The invention relates to a suction device attachment ( ) comprising a suction channel ( ), whereby a component ( ) whose insertion is to be monitored is disposed in said suction channel. A valve (V) having a movable closing body ( ) in the form of a valve ball ( ) that is freely retained in a valve chamber ( ) is mounted behind the component ( ) in the direction of flow (R). The invention aims at ensuring reliable insertion of such a vacuum cleaner attachment that is disposed in such a way as to protect against jamming, destruction or manipulation and that stops the volumetric suction flow when no component or a wrong component is inserted. To this end, an inlet cross section of the valve chamber ( ), which is reduced by the insertion of the component ( ) to be monitored, provokes a sufficient flow deflection (S) so as to move the valve (V) to the opening position, whereby the cross section of the hole is so large that the valve ball ( ) is pressed into its closing position by the pressure of the flow when the component ( ) is not inserted.

A vacuum cleaner for cleaning floors or carpets, having a suction mouth (6), a base plate (5), which encloses the suction mouth (6), and a suction line, electrostatic charging of parts of the vacuum cleaner being provided in order to assist the dust uptake. In order advantageously to provide the vacuum cleaner with the dust uptake being assisted by electrostatic charging, the base plate (5) is electrostatically charged, and the electrostatic charging is carried out by a separate generator (8) provided in the vacuum cleaner.

A device (28) is transported into space for transmitting information from space to earth. On the device (28) there is disposed a plurality of reflectors (10) to be distributed in a raster or grid configuration on a framework (11). Of these reflectors (10), certain reflectors (10), which are selected as a function of the information to be transmitted, are brought into a position in which they reflect light beams, emanating from the sun, to the earth (26). The respective information becomes visible to an observer on the earth (26) in that the selected reflectors (10) give a sequencing of light points which corresponds to the information to be transmitted. On the other hand, the reflectors (10) which are not needed to the display of the respective information are in a position, relative to the sun, which does not allow these reflectors (10) to be perceived as light points by the observer on the earth (26). Any selectable different information may be sent in this manner, using one and the same device (28), to any selectable information regions (29) on the earth.
