Abstract:
A method and apparatus for converting a single instance computer application to a multiple instance application includes disabling the single instance application and linking the executable files associated with the single instance application to routines in a library that includes routines for use by a multiple instance application. Multiple instance metadata that represents the structure of the multiple instance application is automatically created based on metadata that represents the structure of the single instance application. The data from the single instance application is imported to complete the conversion to a multiple instance application.
Abstract:
An integrated memory device comprises a multitude of sense amplifiers which output an amplified data signal on a data line. The data line is forced to a precharge potential when idle. A transistor connects the data line to a precharge potential. The memory device avoids the kickback effect during a data read operation.
Abstract:
The self-erecting structure has resilient lower and upper support loops which provide it with shape and support. Fabric covers the support loops, and is permanently affixed to the support loops. The fabric has a lower, waterproof portion and an upper insect protection portion. The fabric is preferably treated to provide it with insect repellent and insecticide properties. The support loops are made of flexible, resilient rods made of a material, such as a vinylester and fiberglass combination having a diameter selected to enable the support loops to be folded into six loops, whereby the structure can be compactly stored in a rucksack. The method of folding the structure so that it can be stored in such a compact space is also disclosed.
Abstract:
A memory cell having first and second access transistors coupled to a storage transistor is disclosed. During a write 0 operation, a degraded logic 0 is written into the memory cell. By storing a degraded logic 0, the leakage current is reduced.
Abstract:
A system for reservoir control. The system allows segregated production of fluids, e.g. water and oil, to control the fluid-fluid interface. Downhole sensors are utilized in providing data about the location of the interface. This permits the proactive monitoring and control of the interface prior to unwanted intermingling of fluids, e.g. oil and water, during production.
Abstract:
A rack suitable for holding a flexible substrate panel, the rack having a plurality of clamps for providing current to a panel clamped to the rack, the clamps being positioned to uniformly distribute current to the substrate. Seven clamps are used to hold a flexible substrate panel bearing a copper seed or other conductive layer in place on the rack wherein one tautens the substrate while attaching the clamps so as to clamp the substrate in a “wrinkle free” manner. The seven clamps are arranged with 3 clamps on each of the left and right sides and one clamp on the bottom, the clamps making electrical contact with conductive layers of both the front and back surfaces of the substrate panel. The arrangement of the clamps provides adequate support to the substrate, provides for a good and uniform current distribution on the substrate, and allows a relatively large amount of current to flow through the panel without burning off the conductive/seed layers. In one rack, a spring clamp biased open is used wherein a thumbscrew is tightened against a surface of the clamp to force it against its spring into a closed, clamping position. The use of the spring clamp prevents the rotating pressure point contact which a thumbscrew causes.
Abstract:
A process for the preparation of glycerol di- or triphosphate derivatives comprising coupling the phosphate group of a glycerol monophosphate derivative in which one of the phosphate hydroxyls is replaced by a leaving group, with the terminal phosphate group of a mono- or diphosphate compound or a salt thereof, in the presence of a basic catalyst, under anhydrous conditions.
Abstract:
A method for bonding an attachment member to a substrate substantially simultaneously with the formation of a sealing member, and a panel assembly made according to the method. The method includes the steps of applying an adhesive to either the attachment member or the substrate, or both, and holding or otherwise retaining the attachment member against the substrate. A sealing member is deposited on the substrate and encapsulates at least a portion of the attachment member. Heat, generated by the polymeric material or added by an external source, causes the adhesive to cure, creating a strong secure bond between the attachment member and the substrate. The attachment member may then be used to mount the substrate to another surface and securely fixed thereto by an adhesive adapted to bond the surface and attachment member together.
Abstract:
Compounds are disclosed for treating viral infections due to herpes, influenza, hepatitis B, Epstein-Barr, and varicella zoster viruses, as well as cytomegalovirus and human immunodeficiency virus (HIV) by means of lipid derivatives of antiviral agents. The compounds consist of lipid derivatives of phosphonoacids having antiviral activity which are linked, commonly through the phosphate group of the phosphonoacid, to one of a selected group of lipids.The lipophilic nature of these compounds provides advantages over the use of the phosphonoacids alone. It also makes it possible to incorporate them into the lamellar structure of liposomes when combined with similar molecules. In the form of liposomes, these antiviral molecules are preferentially taken up by macrophages and monocytes, cells which have been found to harbor the target human immunodeficiency virus (HIV). Additional site specificity may be incorporated into the liposomes with the addition of ligands, such as monoclonal antibodies or other peptides or proteins which bind to viral proteins.Effective phosphonoacids are phosphonoformic acid or phosphonoacetic acid; lipid groups may be glycolipids, sphingolipids, phospholipids, glycerolipids, or fatty acids. The compounds persist, after intracellular hydrolysis, as the antiviral phosphonoacids. The compounds are effective in improving the efficacy of antiviral phosphonoacids by prolonging the antiviral activity after the administration of the drug has ended, and in preventing retroviral replication in HIV infections which have become resistant to therapy with conventional forms of the antiretroviral agents.
