Title: Gas analyzers
Inventor: KNODLE DANIEL W
IPC: A61B5/097
Filed: 1988-09-14
Granted: 1994-12-13
Abstract: Gas analyzers of the non-dispersive infrared radiation type which are designed to measure the concentration of one gas in a mixture of gases containing that gas.  A novel, electrically modulated, stable, thick film infrared radiation emitter is employed to emit a beam of collimated, focused energy; and two electrically biased detectors are preferably used so that a ratioed, error eliminating output signal can be supplied to the failsafe, signal processing circuitry of the analyzer.  The latter, and a conventional analog-to-digital convertor, supply information to a microcomputer which:  (1) turns the infrared radiation emitter on and off; (2) controls a heater which keeps the infrared radiation detectors at a constant, precise temperature; and (3) controls displays of a variety of information concerning the gas being measured and the status of the gas analyzer.  The microcomputer also accepts ambient temperature, barometric pressure, and other compensation factors. Typically, a disposable airway adapter will be included in the gas analyzer to confine the mixture of gases being analyzed to a path having a transverse dimension of precise and specific length and to provide an optical path across that stream of gases between the infrared radiation emitter and the infrared radiation detectors. The emitter and detectors are incorporated in a transducer head which can be detachably fixed to the airway adapter.

Abstract: ABSTRACT OF THE DISCLOSURE    In a mobile radio telephone system having multiple base stations controlled by a single line control unit. all base stations use a single common control channel in addition to their voice channels to communicate with a mobile station. If a calling signal from a mobile station is received by two or more base stations at once on the common control channel, the base station with the highest received signal level is selected.  If voice signal quality becomes degraded during a call, the call is handed off to the base station with the highest received signal level.

Granted: 1992-11-24
Abstract: Abstract of the Disclosure COUNTERFLOW LEAK DETECTOR WITH HIGH AND LOW SENSITIVITY OPERATING MODES     A counterflow helium mass spectrometer leak detector in which a helium sample passes in a reverse direction through a diffusion pump to a mass spectrometer for measurement.  The diffusion pump includes a conventional foreline and a second foreline provided with an ejector stage.  A test sample is coupled from a test port through a bypass valve to the conventional foreline in a high sensitivity mode and is coupled to the second foreline in a low sensitivity mode.  In the low sensitivity mode, the bypass valve is closed.  An apertured control plate in the diffusion pump controls the relative reverse rates of diffusion from each foreline to the diffusion pump inlet by controlling the rates of vapor flow to annular pumping stages and to the ejector stage.  The ejector stage includes a nozzle for directing a stream of vapor into the second foreline so as to inhibit flow of helium into the diffusion pump and establish a lower reverse diffusion rate at the second foreline.  The disclosed configuration permits measurement of a large range of leak rates.

Abstract: TREATING UNDERGROUND FORMATIONS           ABSTRACT D# 79, 250 -F           Wells  penetrating  oil-producing  and  water-producing intervals may be treated in order to reduce the flow rate of water into the well by isolating the water-producing interval and introducing into it a volume of treating fluids sufficient to invade  at  least  six  inches  into  the  permeable  formation comprising the water-producing interval.   Cased wells may be treated to plug holes in the casing caused by corrosion or casing breaks  by  introducing  a  treating  fluid  into the  formation adjacent to the break.  The treating fluid comprises a material which can be acid catalyzed in a period of from 1 to 16 hours at formation  conditions,  preferably  a  monomer  or  oligomer  of furfuryl alcohol.   The treating fluid contains from 40 to 60 percent furfuryl alcohol and from 40 to 60 percent of an ester, preferably ethyl acetate or butyl  acetate.   The catalyst  is preferably orthonitrobenzoic acid or toluene sulfonic acid in a concentration of from  1 to 4 percent by weight.   The acid and concentration of acid are selected to produce a set time at the formation temperature in the range of from 1 to 16 hours, so the treating fluid will flow into and saturate the pore space of the portion of the formation being treated.
