Patent number: 5006992Abstract: An integrated system for process control in which a process supervisor procedure (which is preferably the top-level procedure) is configured as a modular software structure, with modules which can be revised by a user at any time, without significantly interrupting the operation of the process supervisor. The modular software structure can define control parameters for many process control procedures, and can retrieve data from many sources (preferably including a historical database of process data, which can provide time-stamped data). The supervisor can also call on various expert subprocedures. Preferably the expert subprocedures can also be modified by an authorized user at any time, by calling up and editing a set of natural-language rule templates which correspond to the rules being executed by the expert subprocedure.Type: GrantFiled: September 30, 1987Date of Patent: April 9, 1991Assignee: Du Pont de Nemours and CompanyInventor: Richard D.

Patent number: 5001225Abstract: A continuous hybridoma cell line, designated 7H8, which secretes a monoclonal antibody (MAb 7H8) of the IgM class and which binds to a protein present in species of the genus Plasmodium. MAb 7H8 also recognizes an antigen (antigen Pf93) unique to P. falciparum. Methods of isolating the substantially pure antigen using the antibody of the present invention are disclosed. MAb 7H8 is well suited for use in immunometric assays. Preferred is a two-sited assay developed with MAb 7H8. Anti-idiotypic and anti anti-idiotypic antibodies to MAb 7H8 are disclosed. The antibodies and antigens of the present invention are useful for immunodiagnostic and immunotherapeutic treatment of malarial diseases of man and animals.Type: GrantFiled: December 8, 1986Date of Patent: March 19, 1991Assignee: Georgetown UniversityInventor: Diane W.

Patent number: 4989932Abstract: The invention is a multiplexer which enables light to be sent to and received from samples for simultaneous analysis. A multiplexer is described which uses a transverse probe to reflect light at an angle into an optical rod. The transverse probe is selectively rotated to transmit light to a second optical rod. Various numbers of optical rods may be used in the linear mutliplexer. A multiplexer is also described in which a conjugate optical barrel is utilized to selectively reflect light to various probes.Type: GrantFiled: March 3, 1989Date of Patent: February 5, 1991Assignee: LT IndustriesInventors: Isaac Landa, Michael M.

Patent number: 4990452Abstract: The invention relates to modified subtilisin enzymes which have increased thermal stability. The modified subtilisin enzymes have at least two or more amino acid mutations which confer increased thermal stability. It has been discovered that combining individual stabilizing mutations in subtilisin frequently results in an additive increase in thermal stability. In addition, the invention pertains to cloned mutant genes coding for a subtilisin material having at least two amino acid substitution which has increased thermal stability.Type: GrantFiled: April 12, 1988Date of Patent: February 5, 1991Assignee: Genex CorporationInventors: Philip N.

Patent number: 4985359Abstract: Vectors useful in the construction of cDNA libraries and methods for constructing these vectors are disclosed. According to the invention, a vector includes a polylinker region which is cut to linearize the vector. Oligo(dC) tails having terminal dideoxynucleotides are added to the two 3' ends of the vector. One oligo(dC) tail is removed and replaced with oligo(dT) to which poly(A) mRNA is annealed. The first complementary DNA strand is synthesized and tailed with oligo(dG), which anneals with the remaining oligo(dC) tail, thus circularizing the vector. The mRNA is digested and the second cDNA strand synthesized. Alternatively, the second cDNA strand can be synthesized before circularizing the vector. The resulting vector is used to transform microorganisms to create a cDNA library. The cDNA can be recovered by cleaving the vector at sites within the polylinker sequence.Type: GrantFiled: July 23, 1987Date of Patent: January 15, 1991Assignee: Ilse OberbaumerInventor: Ilse Oberbaumer
