IPC: G05D23/19
Filed: 1992-03-24
Abstract: Abstract of the Disclosure A temperature-controlled environmental chamber includes a resistance heater controlled by a solid state relay and a refrigeration unit including an electronically controlled suction throttling valve connected in the refrigerant line between the evaporator and the inlet of the compressor.  A temperature controller senses the temperature in the chamber and compares it to a set point temperature and outputs a pulse-width modulated control signal indicative of the difference between the two temperatures.  The control signal directly controls the heater relay for substantially continuous variation between minimum and maximum heating conditions.  The control signal is converted to an analog signal for controlling the throttling valve of the refrigeration unit for substantially continuous variation between maximum and minimum cooling conditions, so that the amount of cooling provided is inversely proportional to the amount of heating provided.  A hot gas bypass is provided for maintaining a minimum input pressure on the condenser and a refrigerant bypass is provided to maintain the input temperature of the compressor below a predetermined maximum.

Title: Process and device for detecting measured substances in an ambient substance, especially for detecting gaseous warfare agents in ambient air
Inventor: DOERING HANS-RUEDIGER
IPC: G01N27/66
Filed: 1992-04-09
Abstract: Abstract Process and device for detecting measured substances in an ambient substance. especially for detecting gaseous warfare agents in ambient air A process and a device are used to detect measured substances (A, B) in an ambient substance, especially to detect gaseous warfare agents in ambient air. First, light reaction ions (O2-, H+ with H2O clusters) are generated from a reaction substance (ambient air, H2O), and are added to the mixture (32) of measured substance (A, B) and ambient substance. Reaction ions (O2-,H+ with H2O clusters) thereby attach themselves, in spatially inhomogeneous distribution in a measurement chamber (10), to heavy molecules (MA, MB) of the measured substance (A, B), forming quasi-molecular ions (MA-, MB+). An electric field of a predefined basic frequency and amplitude which varies over time and alternates about a zero line is generated in the measurement chamber (10). The quasi-molecular ion current resulting from the electric field is measured and the measured signal is analyzed. To differentiate a first measured substance (A) from a second measured substance (B) present simultaneously in the ambient substance, first, in a preliminary test for a defined measurement chamber (10), the correlation between the quasi-molecular ion current and the basic frequency, the amplitude, and one asymmetry in the change over time in the electric field strength with respect to the zero line are determined, each time in isolation for the first (A) and for the second (B) measured substance. Then a first measurement is made of the mixture (32) with a first asymmetry, followed by a second measurement of the mixture (32) with a second asymmetry. The measured signals of the two measurements are logically correlated (Figure 2).

Title: Standardizing and calibrating a spectrometric instrument
Inventor: TRACY DAVID H
IPC: G01J3/02
Filed: 1993-01-15
Abstract: A spectrometric instrument which exhibits an intrinsic profile for a sharp spectral line produces profile data for narrow spectral lines. The spectral lines are effected with a high finesse etalon of gold coated polymer. A transformation filter is computed for transforming the profile data to a gaussian profile. A wavelength calibration is combined with the filter to effect a correction matrix which is applied to sample data to generate calibrated standardized data. Iteratively a correction matrix is applied to calibration data to generate standardized calibration data which is utilized for the wavelength calibration. Calibration is effected with an optical standard, an interference etalon and a fringe formula. Etalon effective thickness is first estimated and then precisely determined so that fringe peaks calibrate wavelength.

Title: Ornithine carbamoyl transferase gene and utilization of the dna
Inventor: TSUKAMOTO AKIRA
IPC: C12N9/02
Filed: 1993-03-08
Abstract: This invention relates to a novel ornithine carbamoyl transferase (OCTase) gene, a recombinant DNA containing the OCTase DNA, a transformation system for a basidiomycete, and production of useful proteins using the system.      More particularly, this invention relates to the OCTase gene of Coriolus hirsutus to afford an efficient host-vector system in basidiomycetes (particularly a white rot fungus such as Coriolus hirsutus IFO 4917) for the preparation of useful proteins. OCTase is the enzyme to transform ornithine to citrulline in arginine biosynthesis in organisms. The present invention provides the OCTase genes of C. hirsutus, the useful Arg~ auxotrophic mutant of C. hirsutus deficient in the OCTase gene, the efficient condition for the preparation of protaplasts and the transformation of the mutant with the cloned OCTase gene and the recombinant DNA's including a promoter, a signal peptide-coding DNA and a protein-coding DNA, the construction of the navel host-vector system of C. hirsutus, and the new method of a large scale preparation of useful proteins using this novel host-vector system with a new recombinant DNA technique.      Furthermore, this invention provides a highly efficient method to produce a useful protein such as lignin peroxidase which is difficult to produce by the conventional method.
