Abstract: An apparatus is disclosed comprising a first device for generating aerosol, smoke or vapour from one or more regions of a target, an inlet conduit to an ion analyser or mass spectrometer, the inlet conduit having an inlet through which the aerosol, smoke or vapour passes, and a Venturi pump arrangement arranged and adapted to direct the aerosol, smoke or vapour towards the inlet.

Abstract: The object of the invention relates to a method for scanning with an optical beam (50) using a first acousto-optic deflector (15, 15?) having an optical axis along a Z-axis and at least one acousto-optic crystal layer (14), involving directing the optical beam (50) in the first acousto-optic deflector (15, 15?), and deflecting the optical beam (50) along an X-axis perpendicular to the Z-axis by means of the first acousto-optic deflector (15, 15), during which generating a plurality of acoustic chirp signals (30) in the at least one acousto-optic crystal layer (14) of the acousto-optic deflector (15, 15?) by—generating a first acoustic chirp signal (30a) having a duration of ? in the acousto-optic crystal layer (14), then—generating a second acoustic chirp signal (30b) in the acousto-optic crystal layer (14) within a ? period of time counted from the start of the generation of the first acoustic chirp signal (30a).

Abstract: A wireless telecommunications network comprising a first cell and a user equipment (UE). The UE is operable to measure the RSRP for a communications channel and to monitor fluctuations of the RSRP so as to determine a quality factor for the channel. The UE is configured to determine a weighted RSRP using said quality factor, and report the weighted RSRP to its serving eNB.

Abstract: The invention relates to an arrangement for controlling the flow of gaseous and liquid media, particularly air, comprising of a housing, a number of movable closing members shutting off in closed position the internal cross-sectional area of said housing and an actuating mechanism connected to said movable closing members.

Abstract: The apparatus is suitably disposed within a circular tank and comprises a stationary bridge, a feeding bell, a scraper, driving means, and an optional foam scraping means. The apparatus is characterized in that it has a centrally suspended rotating scraper, mounted from a central vertical shaft and driven by a drive which travels along the rim of the tank, and additionally has at least one rotating drive arm. The drive arm is connected at one end to the drive and at its other end to the feeding bell, which is supported by the shaft of the scraper. The feeding bell is preferably capable of vertical adjustment. The scraper is preferably provided with at least one row of a plurality of vertical stick-like members. A foam scraper is optionally attached to the drive arm. The apparatus additionally contains means for automatically raising or lowering the scraper. depending on the relative rotary momentum between the scraper and the rim drive.
