Patent EP-0269576-A2 (EP)
Inventor: CASAGLIA LUIGI
IPC: B03B9/00
Filed: 1987-05-29
Abstract: The equipment disclosed comprises a plurality of nozzles (10) serving to flood the concrete mix prior to separation of the coarse aggregates by a first wide mesh screen (1); these aggregates are collected at a first recovery station (6), whereas the finer aggregates fall together with the water and cement into a first tank (2) below. The contents of this tank are maintained at a constant level, and fed by a pump (11) into a hydrocyclone (3), whereupon fine aggregates are separated from the water and cement, discharged by the cyclone outlet (4) onto a second, fine mesh screen (5) directly below, and conveyed toward a second recovery station (7), and the water and cement residue is routed into a second tank (8), agitated, and recovered at a third station (9). 
     The method thus implemented is also claimed.

Abstract: The process for making a honeycomb core from a fibrous material preimpregnated with a curable plastic for a lightweight sandwich panel comprises the sequence of following process steps: a. Alternate layering of a prepreg layer 6 and a lattice 4, a prepreg layer 6, a lattice 4, a prepreg layer 6, a lattice 4 and so on until the predetermined thickness of the stack is reached, the lattices 4 being formed by parallel rods 5 at a predetermined spacing and the rods 5 of one lattice 4 being offset in a staggered arrangement with respect to the rods 5 of a neighbouring lattice 4;  b. Pressing of the stack perpendicularly to the axes of the rods 5;  c. Curing of the stack under pressure and heat, and  d. Drawing out of the rods 5 from the stack. The process can be carried out both with horizontal layering and with vertical layering. In particular in the case of vertical layering it is of advantage that all the operations involved can be performed largely automatically by means of drivable devices. <IMAGE>

Abstract: A process for making metal contacts and interconnection lines which are self-aligned to each other is disclosed. After semiconductor devices are formed and an in­sulating/planarizing layer is deposited, a layer of polyimide is deposited. A pattern of trenches into which the metal interconnection lines will be deposited is formed in the polyimide layer. Next, a pattern of contacts to the underlying semiconductor devices is formed in a photoresist layer. This pattern of contacts is subsequently etched into the insulating/planarizing layer. Since both the patterned photoresist layer and the patterned polyimide layer are used as etch masks, thc contact windows through the insulating/planarizing layer and the trenches in the polyimide layer will be aligned with respect to each other. After metal de­position, the metal contacts and interconnection lines will be self-aligned.
