Title: Down hole tool for determination of formation properties
Inventor: ZIMMERMAN THOMAS
IPC: E21B49/00
Filed: 1989-09-22
Abstract: The apparatus of the present invention relates to a down hole tool capable of extraction of valid samples and making pressure measurements useful in calculating formation permeability. The tool incorporates the features of a straddle packer to allow formation fluid specimens to be taken at large flow rates without depressing the pressure below the formation fluid bubble point. When used in combination with a pressure probe the tool is used to obtain meaningful permeability readings in a larger radius area than previously permitted with known designs. Additionally, the apparatus of the present invention allows flow control during the creation of the pressure pulse which enhances extraction of valid samples and the permeability determination. The apparatus is modularly constructed so that in a single descent of the tool, a pressure profile of the zone of interest can be made, a fluid analysis can be made at each station, multiple uncontaminated fluid samples can be withdrawn at pressures above the bubble point, local vertical and horizontal permeability measurements can be made at each station, a packer module can be set at a location dictated by previous measurements and a large scale pressure build up test can be performed. <MATH>

Abstract: A radio transmitter is described, having power control for increasing and decreasing the power of a transmit signal for use in, but not limited to, a time division multiple access (TDMA) radio system. The transmitter has frequency control means (11, 56) for tuning the transmitter to transmit a signal on a selected radio channel, power control means (13, 26) for increasing and decreasing the power of the signal for transmission in preselected time slots to and from a peak value, and control means (20) for causing the power control means to commence increasing the power while the frequency control means tunes the transmitter to transmit outside the selected radio channel and for causing the frequency control means to tune the transmitter to transmit the signal in the selected radio channel when the power has been increased to the peak value. By ramping up from outside the channel, a slower ramp-up can be achieved, giving rise to less interference. <IMAGE>

Abstract: An E.coli strain which 'over-produces' L-tryptophan, comprises, in the genome thereof, a mutant gene which encodes partially-defective tryptophanyl-tRNA synthetase (preferably the trpS378 allele) - which when present in a non-producing strain, is characterized by a temperature-dependent tryptophan auxotrophy - and has a further mutation on the chromosome thereof in at least one gene selected from mtr (especially mtr - 24 ), aroP (especially aroP579 ), tnaA (especially tnaA1 ) and tnaB . The strains may be transformed with a plasmid which carries the tryptophan operon encoding an anthranilate synthase enzyme, freed from feedback inhibition by tryptophan, and/or which possess mutations in at least one gene selected from the trpEDCBA - group (which, when present in a non-producing cell, confers tryptophan auxotrophy thereon). L-tryptophan may be prepared by the cultivation of the said strains at ca. 30 degrees C (preferably in the presence of yeast extract), limiting growth by the concentration of available phosphate (in an appropriate medium), followed by fermentation (in the absence of yeast extract) at from 33 to 37 degrees C.
