Morbo di Morgellons e brevetti correlati

Nuovi studi ed esami di laboratorio hanno consentito di accertare che il morbo di Morgellons è collegato alla presenza nell’organismo dei malati di frammenti costituiti da silicone e da fibre di polietilene. Il polietilene è usato normalmente nell’industria delle fibre ottiche. A queste conclusioni è giunta la Dottoressa Hildegarde Staninger, tossicologa, nell’ottobre del 2006. La ricercatrice precisa che tali materiali sono usati dall’industria delle nanobiotecnologie per incapsulare i viron, ossia virus geneticamente modificati, da una a cento cinquanta volte più piccoli dei virus. Le analisi istologiche hanno rivelato la presenza di tubicini di vetro e di silicone, in pazienti in cui non erano mai state impiantate protesi di silicone nel seno o in altre parti del corpo. Da notare che gli effetti nocivi del silicone sono stati scientificamente dimostrati (...)

Morgellons & patents...

United States Patent patent # 03994437:

Abstract:

A method and apparatus are provided for evenly disseminating by broadcast techniques trace quantities of biologically active chemicals such as nutrients, insecticides, fungicides, growth regulators and the like. The biologically active chemical is encapsulated in a microdispenser such as a filamentary conduit of regulated cross-section and length. The filled microdispensers are then metered into a moving carrier fluid stream, preferably air, and the carrier fluid containing the microdispensers is then evenly dispensed throughout the area. In an alternate preferred embodiment, the microdispensers are coated with a second material which may be either another biologically active material or a sticker for attaching the microdispenser to living organisms such as plants or animals. The method and apparatus is also applicable to biologically active chemicals contained in laminated microdispenser structures for dissemination and release.

Process for the preparation of bead polymers of uniform particle size by polymerization of microencapsulated monomer

Document Type and Number: United States Patent 4427794

Link to this Page: http://www.freepatentsonline.com/4427794.html

Abstract:

Process for the production of bead polymers of improved uniform particle size and uniform quality comprising (a) producing droplets which have a uniform particle size from the monomer or polymerization mixture to be polymerized by spraying the monomer or polymerization mixture into a liquid (continuous phase) which is essentially immiscible with the monomer or polymerization mixture, (b) encapsulating these droplets of uniform size are by shells which are stable under the polymerization conditions to be used and © then polymerizing the encapsulated droplets, and with the provision to maintain in the process steps of droplet production and encapsulation of the droplets certain special conditions.


Encapsulation by interfacial polycondensation, and aqueous herbicidal composition containing microcapsules produced thereby

Document Type and Number: United States Patent 4280833

Link to this Page: http://www.freepatentsonline.com/4280833.html

Abstract:

This invention relates to a process for encapsulation, and particularly to the production of small or minute capsules constituted by a skin or thin wall of polyurea, which involves bringing together an aqueous phase containing a lignin sulfonate emulsifier and a water-immiscible phase containing a water-immiscible material, the material to be encapsulated, plus polymethylene polyphenylisocyanate, dispersing the water-immiscible phase in the aqueous phase followed by addition of a polyfunctional amine. Polymethylene polyphenylisocyanate reacts with the amine to form a solid polyurea shell wall about the encapsulated material. The capsules formed may be directly used as aqueous suspensions.

High concentration encapsulation by interfacial polycondensation

Document Type and Number: United States Patent 4640709

Link to this Page: http://www.freepatentsonline.com/4640709.html

Abstract:

This invention relates to a process for encapsulation, and particularly to the production of small or minute capsules constituted by a skin or thin wall of polymeric material e.g., polyurea, polyamide, polysulfonamide, polyester, polycarbonate, or polyurethane, which involves first providing an aqueous solution (continuous phase liquid) containing an emulsifier which is a water soluble, alkylated polyvinyl pyrrolidone polymer which will form a stable oil-in-water emulsion under the process conditions described herein. A discontinuous (immiscible or organic) phase liquid containing a water-immiscible material which is the material to be encapsulated, plus a first shell wall component; is dispersed in the aqueous liquid to form an oil-in-water emulsion. The second shell wall component is added to the oil-in-water emulsion whereupon the first shell wall component reacts with the second shell wall component to form a solid polycondensate shell wall about the material to be encapsulated. The capsules formed may be directly used as in the form of an aqueous suspension.
