Abstract: A tubular fluorescent lamp (2) comprises an electrode (8) mounted inside the glass tube (4) which is at least partly surrounded by an electrode cover (16) mounted inside the glass tube (4) and situated between the electrode (8) and the wall of the glass tube (4) at a distance from them. According to the invention, a spacer (24) is placed in such a way that when the electrode cover (16) unintentionally is moved from its mounting position in a radial direction relative to the longitudinal axis of the glass tube (4), contact occurs between the electrode cover (16) and the spacer (24), and between the spacer (24) and the inside of the wall of the glass tube (4), preventing the movement of the electrode cover (16) before it comes into direct contact with the inside of the wall of the glass tube (4). Thereby is prevented that the tubular fluorescent lamp cracks and may fall out from its fittings. The spacer is preferably a mica plate (24) with larger diameter than the electrode cover (16).

Abstract: The present invention relates to a device for injecting a cleaning liquid into a teat cleaning cup (3). Each nozzle means (55a-b) is connected to a corresponding and separate cleaning liquid supplying means (27, 29) for injecting said cleaning liquid alternately through said nozzle means (55a-b). The nozzle means (55a-b) are also so arranged in said teat cleaning cup (3) that when alternately injecting cleaning liquid trough each of said nozzle means the teat (9) is deflected away from the nozzle means (55a-b).

Abstract: A method of reducing noise in a video signal which includes a plurality of video frames being composed of a plurality of pixels, the method comprising the steps of: comparing video information contained in a current video frame and a plurality of temporally adjacent video frames; selecting from the current video frame and the adjacent video frames the video information that according to a predetermined condition is likely to be correct for the current video frame; and finally assigning the selected video information to the current video frame to thereby produce a video frame wherein noise has been reduced.

Abstract: A novel and simple method of making a novel concrete slab structure supported on vertical columns (1) and having high strength against punching shear failure involves: placing stirrup cages (3, 3′) with their open sides downwards directly on top of the bottom reinforcement net (7) in a form; laying, crossed bent bars (8) over the top of the column and running along the bottom reinforcement net (7); laying a top reinforcement net (7′) on top of the stirrup cages (3,3′) and the crossed bent bars (8); pouring concrete into the form to a level above the top reinforcement net (7′).
