Granted: 1995-06-21
Abstract: A process for working up household, industrial and other similar waste for the recovery of a fibrous and/or granulated material, in which the waste material is subjected to preliminary comminution, magnetic separation, classification, drying and fractionation, wherein the light fraction resulting from the classification carried out after the magnetic separation is subjected to secondary comminution by cutting, and the heavy fraction to a predominantly granulating secondary comminution and thereafter both comminution products are recombined, dried and fractionated into fibrous matter and granulated material, is to be simplified, and in particular the costs reduced. This is achieved in that before the secondary cutting comminution appliance at least one part stream or the whole stream of the light fraction is diverted and fed directly and/or after comminution in a further comminution unit to further utlization. A device for carrying out the method is also proposed.

The plastic multi-chip package includes a dyepaddle (2) fixed on basd (2a) of package (8), a  printed  circuit  board  (2) having bonding pad (1c), opening (1a), and vacant region (1a), and chips (3a,3b) deposited at the opening (1a) or the  vacant  region (1a) of the printed circuit board (1). The chips are connected  by lead wires (4b).

Abstract: The luminescent screen (10') acting as an  anode  covers  the inside of the front substrate (10). Into the vacuum space  between this and the rear substrate (20), electrons are  emitted  from  an array of parallel filamentary cathodes (40).  Between  the  screen (10') and cathodes (40) the accelerating electrode (30)  comprises a wire mesh deformed into a  number  of  parallel  channels  (30') corresp. to the cathode spacing  and  convex  towards  the  screen (10'). All emitted electrons undergo the  same  acceleration  from the cathodes (40) to the screen.
