Title: X-ray analytical system

Granted: 1981-10-20
Abstract: X-RAY ANALYTICAL SYSTEM                ABSTRACT OF THE DISCLOSURE           An X-ray spectrometer is provided with two channels for detecting characteristic lines of the X-ray source after being scattered by a sample undergoing analysis, in addition to means for detecting electric signals primarily representative of the concentrations of analytes in the sample.  In this way, data is collected which facilitates corrections of the measurements cor-responding to individual analytes for deviations from linearity of intensity caused by variations in interelement effects, and by variations in total-solids concentration, or density, of the slurry, or matrix, in which the analytes are distributed, and by variations in particle size of the total-solids in the sample.  Correction of measurements of total-solids concentration and average particle size of the matrix for each other and for effects of analytes, may also be made.  The  invention may be applied to slurries where the total-solids concentration and particle size may both vary simultaneously from sample to sample, and to dried, solid, or powdered samples where density and particle size may both vary in a similar way.  In an automatic control system, the sample is taken from a slurry and the output signal is employed to control the process to match a norm.  The invention may be em-ployed to improve recovery of desired materials and to reduce the discharge of waste materials likely to cause pollution.

Abstract: VIDEO SIGNAL TRANSLATING CIRCUIT    Abstract of the Invention In a color television receiver luminance channel, transistor amplifier stage (44) develops respective versions of input video signals across load resistors (46, 45) in collector and emitter circuits.  Capacitor (47) links collector to stage's output terminal (0), and parallel combination of inductor (48) and resistor (49) links emitter to output terminal.  Parameter values are chosen to cause stage to provide delay-versus-frequency characteristic compensatory for delay distortion introduced by receiver's IF amplifier.  Use of variable resistor as collector load resistor provides facility for adjustable peaking of luminance channel's amplitude-versus-frequency characteristic while maintaining delay distortion compensation effect.

Abstract: ELECTRON BEAM-CAPILLARY PLASMA FLASH X-RAY DEVICE         Abstract A method and device for the generation of x-rays is described. X-rays can be generated by establishing a high density plasma in a capillary passage and then passing an electron beam there-through.  The device has a cylindrical passage, the ends of which are maintained at a potential difference.  An electrode is main-tained at the potential and is slightly displaced from the higher potential end.  when ions are supplied to the passage, the higher potential end is discharged and a high density plasma is created in the cylindrical passage.  The discharge of the higher potential end of the cylindrical passage causes a discharge of the electrode into the passage forming an electron beam which interacts with the plasma, generating x-rays.

Abstract: ABSTRACT A liquid impregnating system for impregnating, with a liquid, absorbent, compressible product maintained at least in part within the interior compartment of a tub or other container. The impregnating operation is carried out by compressing the product to increase the residence volume in the tub for the impregnating liquid, and directing the liquid into engagement with the product while it is maintained in its compressed condition. Most preferably, the product is a stack of absorbent sheets and the compressing operation is carried out by pressing downwardly on the uppermost sheet of the stack in localized areas intermediate end margins to cause end margins of at least some adjacent sheets in the stack to fan apart. This increases the accessibility of absorbent surface area within the stack to the impregnating liquid.

Abstract: ABSTRACT            A system and method using an integral sandwich structure including an insulative layer-photoconductive layer-conductive layer.  A removable electrode member is positioned above and connected to the insulative layer by a thin liquid layer having a dipole moment greater than zero, a conductivity sufficient to maintain the electrical potential of the surface of the insulative layer at the potential of the electrode member, a surface tension equal to or smaller than the critical surface tension of the insulative layer.  Upon removal of the electrode member, the liquid evaporates in a time period less than the dark dielectric time constant of the photoconductive insulative layer.  A D.C. voltage is applied between the conductive layer and the removable electrode during which time a radiation image is applied to the photoconductive layer to cause an electrical charge image to be produced at the outer surface of the insulative layer.  The method then requires removal of the electrode member and after evaporation of the liquid, the photoconductive layer of the structure is subjected to overall radiation.

Abstract: ABSTRACT           Disclosed is a method of producing highly viscous minerals from a subterranean formation by injection of an acidic, thermal vapor stream without substantial scale build-up in downstream piping, pumps and well bore.  The process comprises heating the formation by injection of heat, preferably in the form of a thermal vapor stream composed of combustion gases and steam and injecting an acidic compound simultaneously with the thermal vapor stream into the formation at a tempera-ture above the dew point of the thermal vapor stream.  The acidic, thermal vapor stream increases the solubility of metal ions in connate water and thus reduces scaling in the downstream equipment during the production of viscous hydrocarbons.
