Patent number: 10086218Abstract: A respiration system is provided with a container (1) in which, by an exothermic chemical reaction of a reaction material, CO2 is removed from the respiration air or oxygen is generated, and with an indicator of the consumption of the reaction material. The consumption indicator has a predetermined amount (7) of material which can be melted by the reaction heat of the exothermic chemical reaction. The material is kept in thermal contact with the container interior in such a manner that a measurement of the total reaction heat, and thus the consumption of reactive material, can be read from the degree of melting of the meltable material.Type: GrantFiled: February 5, 2013Date of Patent: October 2, 2018Assignee: Dräger Safety AG & Co.

Patent number: 7282482Abstract: This invention pertains to the discovery that nerve growth factor (NGF) is capable of preventing further demyelination of nervous tissue in pathologies characterized by the demyelination of nervous tissue (e.g. multiple sclerosis). In one embodiment, this invention provides a method for inhibiting demyelination in a subject having an inflammatory disease of a nervous tissue. The method involves administering an effective amount of NGF, an NGF analogue, or an active fragment of NGF where the effective amount is sufficient to downregulate the production of interferon ? by T cells infiltrating the central nervous system and/or to upregulate IL-10 production by glial cells.Type: GrantFiled: May 10, 2001Date of Patent: October 16, 2007Assignee: The Regents of the University of CaliforniaInventors: Ilse Bartke, Jurgen Unger, Claude Genain, Stephen Hauser
