Abstract: A roller shutter for a window or doorway wall opening, comprising a plurality of elongate slats coupled together to form a slat assembly, and a winding device overlying the slat assembly for winding and unwinding the slat assembly to a fully-closed position, a fully-opened position, and a partially-opened position with respect to the wall opening. The slats are coupled together by flexible coupling links coupled between adjacent slats at both ends of the slats, which permit each slat, when in a fully-opened or partially-opened position with respect to the wall opening, to move linearly away from an adjacent slat in the slat assembly to create a light and air space between the adjacent slats and linearly towards the adjacent slat in the slat assembly to close or restrict the light and air spaces, and angularly with respect to the adjacent slat in the slat assembly to enable the slat assembly to be wound onto or unwound from the winding device.

Abstract: A telescoping protective cowling for removing part of a machine tool. The device includes at least three elements consisting of panels and one of which is stationary or relative to the frame and provided with a window with inside edges restricting the freedom of movement of a moving part. The second panel is slidable relative to the first panel along two axes, is longer than the window of the first panel and is provided with a window within which the moving part is free to move. The third panel is movable and substantially larger than the window in the first panel and receives the moving part in its central portion. As a result, the movements of the moving part in the plane of the two axes in the window in the first panel means that the second panel has a proportional mobility and is thus able to fill the opening of the window in the first panel after it has been left clear by the third panel following the movements of the moving part.

Abstract: A closure system for a sliding main door and a sliding screen door system of the type typically used in houses and some commercial buildings operates to permit three modes of operation of the sliding screen door and the sliding main door relative to one another. In a first mode of operation handles on the doors freely pass by one another and the two doors may be operated completely independently of one another. The handle on the sliding screen door is capable of movement to different vertical positions; and in another position, cooperating surfaces on the two handles cause the sliding screen door always to be closed when the main door is closed. When the main door is opened, however, the sliding screen door in this mode is capable of movement back and forth independently of the main door to the extent of the opening of the sliding main door.

Abstract: A protective panel for the work area of a machine tool, consisting of a plurality of segments which are movably interconnected by connection elements.
