Patent number: 8026309Abstract: A process is provided for producing a compatibilized polymeric blend. A first thermoplastic polymer and a reactive moiety are provided to a progressive melt kneading apparatus. The reactive moiety comprises a first reactive group capable of reacting with the first thermoplastic polymer but not a second polymer and a second reactive group capable of reacting with the second polymer but not the first polymer. The first thermoplastic polymer and the reactive moiety are then melt kneaded so that the first reactive group reacts with the first thermoplastic polymer and the second reactive group is grafted to the first thermoplastic polymer, forming a molten self-compatibilizer. A molten second polymer is then provided. The molten self-compatibilizer is melt kneaded with the molten second polymer so that the second reactive group reacts with the second polymer to form a compatibilized polymeric blend. Also provided are articles formed from the compatibilized polymer blend.Type: GrantFiled: February 29, 2008Date of Patent: September 27, 2011Assignee: PRS Mediterranean Ltd.Inventors: Izhar Halahmi, Oded Erez, Adi Erez

Patent number: 7970455Abstract: An ingestible pill platform for colon imaging is provided, designed to recognize its entry to the colon and expand in the colon, for improved imaging of the colon walls. On approaching the external anal sphincter muscle, the ingestible pill may contract or deform, for elimination. Colon recognition may be based on a structural image, based on the differences in diameters between the small intestine and the colon, and particularly, based on the semilunar fold structure, which is unique to the colon. Additionally or alternatively, colon recognition may be based on a functional image, based on the generally inflammatory state of the vermiform appendix. Additionally or alternatively, pH, flora, enzymes and (or) chemical analyses may be used to recognize the colon. The imaging of the colon walls may be functional, by nuclear-radiation imaging of radionuclide-labeled antibodies, or by optical-fluorescence-spectroscopy imaging of fluorescence-labeled antibodies.Type: GrantFiled: May 19, 2005Date of Patent: June 28, 2011Assignee: Spectrum Dynamics LLCInventors: Yoel Zilberstein, Michael Nagler, Benny Rousso, Izhar Halahmi
