Abstract: Materials variously treated with sodium silicate were studied until enough information was obtained to find a way to solve the problems that have prevented sodium silicate from being the used as a fire retardant. These problems are: 1) water solubility (miscible with water), which results in extensive leaching when exposed to water, 2) cracking, chipping and peeling of treated surfaces, and 3) surface granulation. During flame tests it was discovered that sodium silicate formed a foam-like material, and this material was found to have become water insoluble, yet its elemental composition had remained virtually identical to that of the unmodified sodium silicate. This investigator proposes that under the influence of heat and dehydration, sodium silicate undergoes a polymerization process resulting in particles sizes too large to dissolve in water, and then developed a mechanism to explain how the process could occur.

Abstract: A catheter for delivering therapeutic and/or diagnostic agents directly into the tissue surrounding a bodily passageway. The catheter comprises at least one needle cannula able to be projected outboard of the catheter so as to deliver the desired agents to the tissue. The catheter also preferrably includes one or more inflatable balloons.

Abstract: Angiogenesis healing factors residing in omentum-derived lipid fractions with or without gangliosides or their synthetic equivalents can be used to treat myocardial ischemic conditions including but not limited to myocardial infarction, angina, as well as in heart transplant, vascular grafts, and re-opened vessels leading to improved vascularization, perfusion, collagenization and organization of said lesions; the involved and adjacent tissues.
