Patent DE-4008379-A1 (DE)
IPC: C23G1/36
Filed: 1990-03-15
Abstract: In a process for regenerating alkaline solutions for pickling aluminium, in which aluminium hydroxide is recovered, a pickling solution containing alkali hydroxide, aluminate, a complex builder and other additives is transferred from a pickling bath into a reactor section consisting of at least one reactor, where aluminium is precipitated as aluminium hydroxide. The temperature of the pickling bath is higher than that of the reactor section. The process is operated so that the concentration of aluminate, alkali and gluconate and the temperature in the pickling bath, on the one hand, and the temperature drop from the pickling bath to the reactor section, on the other hand, are adjusted so that the pickling solution in the pickling bath is undersaturated or metastably supersaturated in relation to the precipitation of aluminium hydroxide but unstably supersaturated in the reaction section. A device for carrying out the process of the invention is also disclosed.

Title: Detection of winding faults on package end - has signals from scanning camera evaluated to allow for package rotation
Inventor: MASAI TETSUJI
IPC: B06B1/06
Filed: 1991-07-25
Abstract: Winding faults (15) in which yarns run across the end (14) of a package (P) are detected by shining a light (20) on it and scanning the picture produced with a camera (23) having charge coupled detector elements. The signal from each pixel is encoded in binary form, stored and fed to a computing unit. A number of pixels in the direction (x) are taken along the scanning line (y) and, where the value changes from 0 to 1, a new start point F(x,y) is taken from where the process is repeated. A visible light beam Lo is taken through a slot (21) to give a parallel beam L1 which is deflected on to the package face (14) by a mirror (22) so that the winding fault (15) throws a shadow.  The reflected beam L2 produces an image in the camera (23) via the mirror (22). because the package (P) is rotated the straight line fault (15) gives a curved image which is sensed. USE/ADVANTAGE - It gives a reliable means of detecting winding faults across the package face.
