Title: Stable polymerized hemoglobin blood-substitute
Inventor: RAUSCH CARL W
IPC: C07K1/107
Filed: 1996-03-22
Granted: 2009-08-18
Abstract: A method for producing a stable polymerized hemoglobin blood-substitute from blood characterized in the use of a chromatographic column, is disclosed. The method of this invention includes mixing blood wit h an anticoagulant to form a blood solution, washing the red blood cells in the blood solution and then separating the washed red blood cells from the white blood cells. This method also includes disrupting the red blood cells to release hemoglobin and form a hemoglobin solution, which is then treated by high performance liquid chromatography to form a hemoglobin eluate. The hemoglobin eluate is then deoxygenated, contacted with a first reducing agent to form an oxidation-stabilized deoxygenated hemoglobin solution, and mixed with a cross-linking agent to form a polymerization reaction mixture, which is then polymerized. The polymerized hemoglobin solution is then diafiltered with a physiologic solution and with a reducing agent, whereby the polymerized hemoglobin solution is made physiologically acceptable, and whereby the reducing agent scavenges oxygen, to form a stable polymerized hemoglobin blood-substitute, which is then package d and stored in an atmopshere substantially free of oxygen. Compositions made by the methods are also disclosed, as are methods of therapeutically, or prophylactically, treating a vertebrate to increase tissue oxygenation, or prevent oxygen depletion, in tissue of the vertebrate .

Abstract: A lightweight intervention system is described for use with single bore and dual bore intervention operations and which can be used with both horizontal trees and conventional trees and with wellheads without trees mounted thereon.  The system is based on a two-part intervention apparatus; the lower part provides the pressure control and consists of an xmas tree or wellhead connector and structural housing in which a sub-sea test tree is located and is coupled to the xmas tree and an upper part, a disconnectable section, attaches to the lower part and consists of a sub-sea test tree latch housed within an xmas tree connector and additional pressure control equipment as required. This general structure can be configured in various ways to create different embodiments for use with horizontal trees and conventional trees which have a single through-bore requirement and a dual bore requirement respectively. With horizontal trees access to the annulus space depends on the type of proprietary valve system used in the tree. The intervention apparatus may also be used directly on wellheads where the tree has been removed.

Abstract: An improved current collector for use in lithium ion batteries includes an aluminum grid of the type used for making conventional current collectors that is coated with a layer of zinc, the outermost portion of which is oxidized to zinc oxide. The current collector is made by first cleaning an aluminum grid in an aqueous basic solution to remove its outer layer of alumina. The cleaned aluminum grid is then coated with zinc by contact with an aqueous solution of zinc oxide. The coated aluminum grid is rinsed and dried in air to oxidize the outer surface of the zinc and form an outer layer of zinc oxide. The resulting zinc-coated current collector can be made into a battery with a higher conductivity at the interface between the current collector and the electrode active materials than a battery made with a conventional aluminum current collector. It also has a rough outer surface which improves its adhesion to the polymeric layers used in constructing a plastic lithium ion battery.

Abstract: A planar array antenna (12) having radiating elements characterized by dual simultaneous polarization states and having substantially rotationally symmetric radiation patterns. A distribution network (16), which is connected to each dual polarized radiator, communicates the electromagnetic signals from and to each radiating element. A ground plane (14) is positioned generally parallel to and spaced apart from the radiating elements by a predetermined distance. The conductive surface of the ground plane operates to image the radiating elements over a wide coverage area, thereby enabling a radiation pattern within an azimuth plane of the antenna to be independent of any quantity of radiating elements.  A central polarization control (18) network (PCN), which is connected to the distribution network (16), can control the polarization states of the received signals distributed via the distribution network by the radiating elements.
