Reliable and secure transmission of information over the Internet is provided in a financial transaction processing system. The system electronically integrates data captured in heterogeneous information systems and transmits that data reliably and securely over the Internet between multiple diverse servers. The system includes at least one local computer system which electronically captures information input by a user of the computer system. The local computer system can access one or more remote servers via the Internet for form a dynamically reconfigurable wide area network (WAN). The remote servers electronically transfer data to heterogeneous information systems translated into their natural communications protocol and data format.

The present invention describes a purified and isolated nucleic acid molecule which encodes for the biosynthetic pathway of tetracycline, chlortetracycline or an analogue thereof. The invention relates to the isolation and cloning of the nucleic acid molecule in an isolated fragment from Streptomyces aureofaciens and the expression of the biosynthetic gene in a heterologous host such as Streptomyces lividans.

Recombinant S. aureofaciens cells are provided. These cells comprise:(a) at least one CTC 11 gene; and (b) optionally(i) a CTC 09 gene;(ii) a CTC 03 gene; or(iii)a combination thereof;wherein:the CTC 11 gene is chromosomal, extra-chromosomal, or chromosomal and extra-chromosomal;the CTC 09 gene, CTC 03 gene, or a combination thereof is chromosomal, extra-chromosomal, or a combination thereof;expression of the CTC 11 gene is enhanced over that of a wild-type S. aureofaciens cell; andoptionally, the CTC 09 gene, the CTC 03 gene, or both of the CTC 09 gene and the CTC 03 gene are inactivated.The present invention also contemplates vector pLP21329 and vectors for allelic replacement in a S. aureofaciens host cell. The vectors comprise:(a) a functional E. coli origin of replication;(b) a functional Streptomyces origin of replication;(c) a functional gene that imparts a positively selectable phenotype on the host cell; and((d) a ribosomal S12 gene which is expressed in Streptomyces such that it imparts sensitivity to streptomycin to the host cell.In another embodiment, a method of mutating a target gene of a biosynthetic pathway of Streptomyces is disclosed. The method comprises(a) replacing the genomic copy of the target gene with a selectable marker gene through homologous recombination to form a first recombinant strain; and(b) replacing the selectable marker gene in the first recombinant strain with an altered copy of the target gene through homologous recombination to form a second recombinant strain.

The invention features a novel hybrid interferon species that comprises a chain of 161 and/or 162 amino acids. The hybrid is novel not only for its new structure, but also because the hybrid comprises a shortened or truncated segment of alpha interferon, and hence, an entirely new interferon species which is not occurring in nature.

The invention teaches means for detecting unauthorized tampering or substitutions of a device, and has particular utility when applied on a "seal" device used to secure a location or thing. The seal has a transparent body wall, and a first indicia, viz., a label identification is formed on the inside surface of this wall. Second and third indicia are formed on the outside surface of the transparent wall, and each of these indicia is transparent to allow the parallax angled viewing of the first indicia through these indicia. The second indicia is in the form of a broadly uniform pattern, viz, many small spaced dots; while the third indicia is in the form of easily memorized objects, such as human faces, made on a substrate by means of halftone printing. The substrate is lapped over the outside surface of the transparent wall. A thin cocoon of a transparent material, generally of the same material as the substrate such as plastic, is formed over the seal body and specifically over the transparent wall and the second and third indicia formed thereon. This cocoon is seamless and has walls of nonuniform thickness. Both the genuineness of the seal and whether anyone has attempted to compromise the seal can thus be visually determined upon inspection.
摘要:
Methods of constructing and using gene expression systems to indicate the pertubation of fungal cell envelopes are provided. The recombinant genes produce indicator cleavage enzymes such as .beta.-galactosidase when galactose is able to enter the cell, despite the presence of glucose, through discontinuous cell envelopes. The indicator cleavage enzymes such as .beta.-galactosidase cleaves a colorimetric indicator placed in the media to produce an easily detected measurement of altered cell envelope permeability.

A steam trap monitor positioned downstream of a steam trap in a closed steam system includes a first sensor (the combination of a hot finger and thermocouple well) for measuring the energy of condensate and a second sensor (a cold finger) for measuring the total energy of condensate and steam in the line. The hot finger includes one or more thermocouples for detecting condensate level and energy, while the cold finger contains a liquid with a lower boiling temperature than that of water. Vapor pressure from the liquid is used to do work such as displacing a piston or bellows in providing an indication of total energy (steam+condensate) of the system. Processing means coupled to and responsive to outputs from the thermocouple well hot and cold fingers subtracts the condensate energy as measured by the hot finger and thermocouple well from the total energy as measured by the cold finger to provide an indication of the presence of steam downstream from the trap indicating that the steam trap is malfunctioning.
摘要:
The invention is a tool to aid in the attaching of coaxial electrical cable ends to a half of a coaxial cable connector assembly. In detail, the tool comprises a wrench to prevent rotation between the connector halves when the connector halves are joined. A shaft is included having a threaded end for coupling to the recess of the other connector half. Finally, a drive preferably in the form of a portable electrical drill, is used to rotate the drive. Thus, with the joined connector halves installed in the wrench, so that rotation therebetween is prevented, the shaft can be threaded into the other connector half and thereafter coupled to the drill. The connector half to which the coaxial cable is to be joined is aligned with the prepared cable end and fed into the threaded recess as the wrench and joined connector halves are rotated.

A container includes a body forming an interior and having a sidewall with a distal edge portion forming an opening to the interior. A liner is disposed over the opening and includes an inner portion and an outermost radial portion disposed radially outwardly of the distal edge portion. A lid including an interior surface and at least one tab projecting inward from the interior surface is disposed over the liner and engages the body. The liner is sized to be releasably rotatably secured within the lid while the lid is initially attached to the body so that the at least one tab remains generally rotationally fixed relative to the outermost radial portion while being assembled to the body. The at least one tab is arrange to press the outermost radial portion while the lid is being removed from the body so that the outermost radial portion maintains a bent orientation.
