Title: Preservation by vaporization
Inventor: BRONSHTEIN VICTOR
IPC: C12M1/00
Filed: 2005-06-01
Granted: 2018-01-23
Abstract: Significant research is being done to develop and improve delivery mechanisms for biopharmaceuticals and vaccines, including pulmonary (inhalation), nasal, transdermal, and oral alternatives. Market projections indicate that the delivery of proteins and vaccines by inhalation and oral formulation has become and will continue to be increasingly important. These delivery mechanisms, to be effective, will require better stabilization of the biologicals so that they can maintain potency and effectiveness at ambient temperatures for extended periods of time. The novel Preservation by Vaporization (PBV) Technology described herein provides cost-effective and efficient industrial scale stabilization of proteins, viruses, bacteria, and other sensitive biologicals, thereby allowing a production of products that are not possible to be produced by existing methods. The suggested new PBV  process comprises primary drying under vacuum from a partially frozen state (i.e. slush) at near subzero temperatures followed by stability drying at elevated temperatures (i.e., above 40 degrees Celsius). The new suggested method can be performed aseptically in unit doze format (in vials) and/or in bulk format (in trays, bags, or other containers). The drying can be performed as a continuous load process in a manifold vacuum dryer comprising a plurality (e.g., 30) of vacuum chambers attached to a condenser during the drying.

Title: Self-diverting resin systems for sand consolidation
Inventor: AYOUB JOSEPH A
IPC: E21B43/02
Filed: 2001-04-23
Granted: 2010-03-30
Abstract: Herein is described a fluid that is useful in consolidating a formation without the use of a gravel pack and screen. In particular, the fluid is useful in consolidating heterogeneous formations where the permeability is not uniform over the total formation thickness, e.g. a formation having at least a first layer and a second layer, wherein the permeability of the first layer is greater than that of the second layer. The fluid comprises at least one of a resin, a curing agent, and a surfactant, wherein the fluid is self-diverting. Optionally, a catalyst or other additives, such as an oil wetting agent, can be used. Fluids of the present invention are self- diverting, i.e. in a formation comprising at least a first layer and a second layer, wherein the first layer has a higher permeability than the second layer, the depth of penetration of the fluid into the second layer will be greater than that predicted from the permeability ratio (the ratio of the permeability of the first layer to that of the second layer). Self-diversion can be achieved by structuring the fluid by incorporation of another phase, either liquid or gas, or by using an additive in the fluid. Also disclosed are methods for using such a fluid to consolidate a formation, especially a heterogeneous formation.
