A multilayer laminated body has a determinate system of hollow passages and is formed by an assembly of flat layers of polymeric materials having major dimensions in orthogonal X and Y directions and a thickness dimension in a Z direction perpendicular to the X and Y directions. Selected ones of the layers have openings extending through in the Z direction, and other layers have canals formed in an X-Y plane. The openings and canals form parts of hollow passages so that assembly of multiple layers joins openings and canals forms complete and continuous passages through the assembled layers. Layers joined in pre-laminate assemblies are assembled together in precise relative positions for desired alignment of the canals and openings. The passages can be filled with optically conductive material or electrically conductive material and electrodes can be appropriately positioned for acting on fluids passing through the body.

Thin laminated microstructure with precisely aligned openings

Apparatus for preventing formation of a sediment layer at the bottom of a tank containing a liquid mixture such as crude oil, refinery products and petrochemical products which tends to form a precursor in the form of a thickening precipitation zone above the bottom. The deposit of sediment is prevented by disturbance of the precipitation zone. The disturbance is created in the form of an overall disturbance pattern with local disturbance regions with vibrating bodies such as strings or bells strings excitable to vibrate and immersed in the liquid mixture. Exciting elements including push and pull units cause the strings or bells to vibrate in fundamental and harmonic overtones and deflect components of the mixture as a function of the amplitude of said sound wave components.

Apparatus for avoiding sedimentation

A method and apparatus for preventing the deposit of sediments from multi-material mixtures, such as crude oil (4), refinery products and petrochemical products, at the bottom of a tank (T), in which the sediments form a precursor in the form of a thickening precipitation zone (4.2). The deposit of sediments is prevented by disturbing the formation of the precipitation zone (4.2). The disturbance is created in an overall disturbance patterns (S) with local disturbance regions (L) according to a disturbance pattern (S) and is brought about by disturbance apparatus (V) in a disturbance zone hydro-kinetically by the supply or removal of crude oil (4) in the disturbance zone through a pipe system (7).
