Patent CA-2495301-A1 (CA)
Inventor: CATTEAU FREDERIC
IPC: G01F11/26
Filed: 2003-08-08
Abstract: The invention relates to a dosing apparatus (7) consisting of: a buffer chamber (6), the upper part of which communicates with the main chamber (3) of the fluid or powder container (1); and a dosing chamber (2) comprising a passage which leads to the lower part of the aforementioned buffer chamber (6). According to the invention, the container is tilted downwards such that the buffer chamber is filled at least partially and said container is then set upright such that the fluid or powder in the buffer chamber can flow into the dosing chamber. The invention is characterised in that the passage between the buffer chamber and the dosing chamber is a constricted channel (80) which forms an anti-siphon and which causes the formation of a bubble in order to restrict the release of the fluid or powder when the container is being set upright.

Inventor: ENGEL MANFRED
IPC: B02C18/18
Filed: 2005-03-31
Abstract: The invention concerns an arrangement for the adjustment of the position of a shearbar with respect to knives of a chopper assembly. The arrangement includes a first adjusting drive to position the first end of the shearbar at a predetermined first spacing from the knives and a second adjusting drive to position the second end of the shearbar with respect to the knives until a spacing measurement arrangement indicates that the spacing between the shearbar and the knives is less than a threshold value. An analogous procedure is applied to the first adjusting drive. On the basis of the measurement values the shearbar is brought into a position that corresponds to a desired gap between the shearbar and the knives.

Abstract: The invention relates to a window element 1 for insertion in a window aperture 7 in an outer skin 5 of a means of transport, in particular of an aircraft.   According to the invention, the window element 1 has a cover pane 10 which ends substantially flush with the outer skin 5 to achieve a fluid-dynamically favourable, largely flat shape of the outer skin 5.   As a result of the presence of an additional back-ventilated cover pane 10 arranged in front of the actual outer pane 26 of the window element 1, a fluid-dynamically favourable integration of the window element 1 into the outer skin 5 of an aircraft fuselage airframe is achieved.   Any deformation, especially any buckling of the outer pane 26 of the window element 1 as a result of a pressure difference between the interior of the aircraft fuselage airframe and the exterior space at high flying altitudes has no fluid-dynamically disadvantageous effect as a consequence of the outer pane 26 being covered by the previously-arranged cover pane 10 which is inserted substantially flush into the outer skin 5 of the aircraft fuselage airframe. Any deformation of the cover pane 10 is largely eliminated by the back-ventilation.   In addition, the components for forming the window element 1 according to the invention can be produced and assembled easily from the production technology point of view.
