摘要:
By the invention is provided a roof window operating arrangement (10) and a roof window (1) employing the operating arrangement (10). The operating arrangement (10) is configured to provide manual opening and closing of the window (1) and further automatic closing of the window (1). The operating arrangement (10) has a winding drum (23; 123; 223) for winding up an operating element (30; 130; 230), such as a cord, in order to automatically close the window (1). The window may be manually opened because a free wheel clutch (40; 140; 240) enables the operating element (30; 130; 230) to be manually withdrawn. The operating element (30; 130; 230) is releasable from the window (1) and when released the operating element (30; 130; 230) is withdrawn into the operator housing (20; 120; 220) by a spring (24; 124; 224).
摘要:
The set of panels (300) comprises plate members including a top member, a bottom member and two side members and cooperates with a supporting frame to form a window lining spanning a thickness of a roof structure (200) from a window frame (100) of a window. The shape of the plate members is defined by the shape of the supporting frame.

The rotary atomizer is intended for a spray drying apparatus and comprises a feed supply pipe (104), a drive motor (102), a drive shaft (107), one or more bearings (111, 112, 113) supporting or guiding the drive shaft, and an atomizer wheel (106). At least one of the bearing or bearings (111, 112, 113) is a foil bearing. An additional supply device (114) for air or gas may be provided to be connected to the at least one foil bearing (111,112). Furthermore, the additional supply device (114) may be connected to further opening into a position nearby the atomizer wheel (106) by means of a branch connection (115).
摘要:
The roof window comprises a stationary frame (1) adapted to be built into a structure and having a top member (12), two side members (13, 14) and a bottom member (11), and defining a frame plane, a sash (2) having a top member (22), two side members (23, 24) and a bottom member (21), and carrying a pane (3) and defining a sash plane in parallel with the pane, an intermediate frame (4), and at least one first hinge connection (15) for connecting the sash (2) and the intermediate frame (4) to the stationary frame (1). Releasable locking means (16) for releasing the first hinge connection (15) are provided, and at least one second hinge connection (25) for connecting the sash (2) to the intermediate frame (4), as well as operating means (8) for opening and closing the sash relative to the frame. In order to provide a substantially weather-proof transition between the roof window and the surroundings, a first set of cover elements (100) is provided on the stationary frame and a second set of cover elements (200) provided on the sash. The second set of cover elements includes a top sash cover element (200) and the first set of cover elements includes a top frame cover element (100). The top sash cover element overlaps the top frame cover element to a maximum opening angle when the sash is rotated in a first direction relative to the frame plane, but is releasable from the overlap to allow a rotation of the sash in a second direction opposite the first direction.
摘要:
A nozzle for cleaning-in-place of a vessel has a nozzle body to be connected to a wall of the vessel and defining an opening, a nozzle insert is contained within the nozzle body and is able to assume at least two distinct positions relative to the nozzle body, a first position in which the nozzle insert is retracted into the nozzle body and a second position in which the nozzle insert is advanced in the axial direction relative to the nozzle body and protrudes into the vessel. Apertures are exposed in the second position to allow distribution of a cleaning fluid. The nozzle insert has two nozzle insert parts, in mutual abutment in the first position and spaced from each other in a direction transverse to the axial direction in the second position to form a gap between adjacent nozzle insert parts, the apertures being exposed in the gap.
