Title: Cooling of air in an aircraft
Inventor: SOLNTSEV ALEXANDER
IPC: B64D37/32
Filed: 2005-08-11
Abstract: Nowadays in aircraft so-called on-board inert gas generation systems (OBIGGS) are used to generate inert gases, to which OBIGGS cooled bleed air of engines or auxiliary power units is fed. According to an embodiment of the present invention, an air-cooling device for an OBIGGS system in an aircraft is proposed that comprise a bleed position (1). By way of the bleed position (1), cooling air from an air conditioning unit (4) on board the aircraft can be bled, which cooling air can subsequently be used for cooling supply air (18) for the OBIGGS system. Thus, there is no need for an additionalram-air inlet channel for cooling the supply air. Air resistance and weight are thus reduced, and the stability of the primary structure is enhanced.

Abstract: A security device is disclosed that has an image formed upon a substrate. The image has a first printed region and a second different printed region both printed with a same ink formulation of field alignable flakes. At least one of the printed regions has optically variable effects. One of the first and second printed regions at least partially surrounds the other. The second printed region is formed of thin parallel lines and the first printed region has substantially wider lines than are printed in the second printed region. The area density of the ink in a line in the first group of wider lines is greater than the area density of a line in the second group of narrower lines. A surprising effect of this image is that particles or flakes in the ink are field aligned so as to produce a visible kinematic dynamic effect visible in the first region and not visible in the second region when the image is tilted or rotated.

Abstract: Disclosed is a fiber composite component comprising first and second partial elements (1, 2) which at least border each other and are provided with one respective fiber structure (3, 4) and different matrix systems that embed the fiber structure (3, 4) while hardening in a different manner from a liquid state. In order to increase the stability of the connection between the two partial elements (1, 2), the matrix system of the first partial element (1) is liquefied first and irregularly penetrates into the area of the bordering second partial element (2), whereupon the matrix system of the second partial element (2) is liquefied, and the matrix systems are hardened. Embodying the irregular boundary surfaces results in the matrix systems engaging into each other or interlocking such that a boundary surface (5) having an increased shear strength is created. Alternatively, the first partial element is consolidated with a fiber structure (102a) that is not moistened by the matrix system (103) while leaving a transition area (104) which is to be connected to the second partial element (105), whereupon the second partial element (105) is consolidated once the matrix system (106) of the second partial element (105) has penetrated into the transition area (104) of the first partial element (101).
