Patent number: 9598883Abstract: A security device fitted to the base casing of a portable object for securing the portable object is provided. The security device includes a housing having an indentation formed within one face of the housing and a retractable tongue pivotably mounted at one end within the indentation. The tongue has an aperture formed within the tongue's non-pivotal end. In a first mode, the retractable tongue is storable within the indentation and in a second mode, the retractable tongue may be extended beyond the contours of the device allowing for a secondary component to be attached to the aperture.Type: GrantFiled: August 24, 2015Date of Patent: March 21, 2017Inventor: Alexander Gad Avganim

Publication number: 20140194593Abstract: The present invention provides processes for determining the molecular weight of glatiramer acetate and other copolymers. The present invention further provides a plurality of molecular weight markers for determining the molecular weight of glatiramer acetate and other copolymers which display linear relationships between molar ellipticity and molecular weight, and between retention time and the log of the molecular weight. The molecular weight markers also optimally demonstrate biological activity similar to glatiramer acetate or corresponding copolymers and can be used for treating or preventing various immune diseases. In addition, the subject invention provides pharmaceutical compositions for the treatment of immune diseases comprising a polypeptide having an identified molecular weight and an amino acid composition corresponding to glatiramer acetate or a terpolymer.Type: ApplicationFiled: January 31, 2013Publication date: July 10, 2014Applicant: Yeda Research and Development Co., Ltd.Inventors: Alexander Gad, Dora Lis
