Patent CA-2142450-A1 (CA)
Title: Dynamical destabilization of systems characterized by kinetically coupled components using a differential flow
Inventor: MENZINGER MICHAEL
IPC: B01J19/00
Filed: 1993-08-20
Abstract: A method of destabilizing the homogeneous steady state of a dynamical system with two or more dynamically coupled variables through the action of a differential bulk flow of the key species, termed Differential Flow Induced Instability (DIFII), is disclosed.  The DIFII is also applicable to systems with time periodic (limit cycle) and aperiodic (chaotic) states. Turing predicted that in systems characterized by activator/inhibitor kinetics a homogeneous, stable steady state of the reactive system may lose its stability and form inhomogeneous patterns due to the interaction of diffusion and reaction when the diffusion coefficient of the inhibitor is sufficiently greater than that of the activator. This mechanism is believed to form the basis of biological morphogenesis.  The method of the present invention avoids this constraint on the diffusivities in the dynamically coupled two component system by using a differential bulk flow between the activator and the inhibitor species rather than a differential diffusivity. In systems with three (or more) dynamically coupled components the requirement of the presence of an activator species (or subsystem) is relaxed and if there is no activator species (or subsystem) present, the system may be destabilized by a differential flow of its components, in contrast to systems of two dynamical variables.  Technological advantages such as reaction yield enhancement are shown.  The method disclosed herein is shown to be applicable to a wide range of systems including chemical, biological and physical.

IPC: B29C48/305
Filed: 1995-05-03
Abstract: A method of continuously fabricating a cushiony recycled plastic floor tile or wall cover incorporating a decorative printed design wherein a single-ply sheet, made up substantially of recycled membrane and a proportion of discrete fibres sufficient to create a cushion effect in the tile is extruded at an extruding temperature in the range of 300°F-350°F in a hot state of semi-solidity in which it can be drawn under tensile load without reducing in thickness. The hot substrate proceeds immediately into the nip between laminatinq rolls and a transparent cover film, having decorative imprinting on one surface is passed closely alongside one of the laminating rolls to apply radiant preheat to it, before passing on into the nip with the substrate. The cover film utilizes the heat in the substrate and the heat imparted by one of the laminating rolls to bring it to bonding temperature while compressive pressure is applied to autogeneously heat weld the substrate and cover film in surface to surface sealed contact without the imposition of air bubbles or wrinkles between them. The welded product is then cooled and cut into discrete sizes, which are applied as very durable, tough, cushiony floor tile or wall covering.
