Title: Incinerator filter dust - is sieved to give a coarse fraction with low neutral salts and heavy metal cpd. content to reduce vol. for special disposal
Inventor: GRAHLHER MANFRED
IPC: B03B9/04
Filed: 1991-10-26
Abstract: The filter dust from incinerators, and especially rubbish incinerators, is sieved to give a coarse fraction with a low content of neutral salts and heavy metal cpds. Any residual water soluble salts and heavy metal cpds. are washed out of the coarse fraction or separated by a caustic process.

The filtrate from the washing or caustic treatment is given a sulphide precipitation in a pH range of 3-4, to separate dissolved brass and bronze such as zinc and cadmium to give a usable concentration. The washed filtrate, and also the filtrate cleaned of bronze and brass, is evaporated to increase the dry content matter, and the vapour is used to moisten the fine fraction through sieving. The sieving is pref. through a channel wheel system. USE/ADVANTAGE - The technique is for the treatment of incinerator filter dust which contains a high portion of water soluble salts and heavy metal cpds. such as chlorideed dioxin/furan etc. The sytem reduces the amt. of dust which has to be given special disposal treatment.

Patent DE-4201272-A1 (DE)
Inventor: STAIGER ULRICH
IPC: G03B21/53
Filed: 1992-01-18
Abstract: The present invention relates to a method of automatically focusing glass-mounted and glassless slides, said method permitting quick and reliable focusing as a function of the thickness of the glass mount. According to the invention, this is attained in that the multiple IR radiation images of a mask aperture reflected from glass-mounted slides are focused onto a CCD line sensor. Number and spacings of the images are subsequently detected with respect to their sequence on the CCD line sensor via electronic means, the second image detected is projected onto a predetermined cell of the line sensor by shifting an autofocusing device and projection lens carrier by means of electromechanic adjusting means, said cell corresponding to a focused projection image of a glassless slide. Simultaneously, a signal is produced by electronic means which signal corresponds to the spacing between a first and a second aperture image and causes an adjusting means to shift the projection lens within the autofocusing device carrier by the spacing determined.
