Title: Method for simple analysis of relative nucleic acid  levels in multiple small samples by cytoplasmic dot  hybridization
Inventor: WHITE BRUCE A
IPC: C12Q1/68

Abstract: ? 280 HRL/JEL     Abstract A simple technique for the simultaneous measurement of relative levels of a specific mRNA in numberous small samples of biological specimens is described.  The technique involves denaturation of cytoplasmic preparations, followed by dotting of up to 96 samples onto a single sheet of nitrocellulose, hybridization with a 32P-labeled cDNA plasmid, autoradiography, and scanning.  By analyzing cytoplasmic preparations instead of purified RNA, manipulations of multiple samples prior to analysis are minimized.  Experiments with a clonal line of rat pituitary tumor (GH3) cells show that this technique can be employed to follow the induction by Ca2+ of prolactin mRNA sequences, employing cytoplasm prepared from as little as 2.5 x 104 cells.  The specificity of the technique for prolactin mRNA is shown by employing GC cells, a GH3 cell variant lacking detectable prolactin mRNA sequences.  Experiments with cultured rat hemipituitaries show that the prolactin mRNA present in cytoplasm corresponding to as little as 1/100 of a pituitary can be readily detected.  This technique is quite simple, can be quantified, and permits the ? 280 HRL/JEL     simultaneous analysis of multiple samples while requiring very small amounts of material for analysis.  Hence, it should be quite useful for example for studies with various experimental systems of the regulation of specific mRNA levels.

Abstract: ABSTRACT OF THE DISCLOSURE           Part of liquefied carbon dioxide is subjected to adiabatic expansion so that the remainder becomes snow-like dry ice due to heat of vaporization and heat of sublimation while a liquid is sprayed to produce a snow-like frozen liquid.  The snow-like dry ice and the snow-like frozen liquid are mixed and the mixture is compressed and pelletized to produce hard particles each of which consists of a particle of snow-like dry ice coated with snow-like frozen liquid.  The thus obtained particles are projected by compressed air or water under high pressure against an object to be cleaned.  Wet type abrasive blasting can be effected because when the particles are projected against the object, the frozen liquid which coats the surfaces of snow-like dry-ice particles is broken.

Abstract: DISPLAY TEMPERATURE COMPENSATOR             FOR ELECTRIC METER            ABSTRACT OF THE DISCLOSURE      A display temperature compensator employs the non linear temperature coefficient of resistance of a thermistor to non linearly vary the control voltages fed to a liquid crystal display.  At low temperature, substantially the entire supply voltage is available to control the liquid crystal display segments,  At higher temperatures, the thermistor contracts the range of control voltages fed to the display in order that non-selected display segments remain off.  A thermistor is used which has a non linear temperature coefficient of resistance which, when combined with selected fixed resistance value, substantially compensates for the non linear threshold voltage of the liquid display.

Abstract: METHOD FOR SEGMENTING BUILDING BOARDS        AND APPARATUS THEREFOR       Abstract The present invention relates to a method and apparatus for segmenting groove molded building boards.          In a preferred embodiment, a sheet of groove molded board is conveyed onto a first apparatus which separates the side edge trim scrap from the board.  The board then passes onto a segmenting apparatus comprising a first horizontal conveyor, an inclined conveyor, a second generally horizontal conveyor, and adjustably mounted roller assemblies.  The first apparatus removes the side-edge trim scrap from the board and the second segmenting apparatus breaks the groove molded board transversely along the groove molded lines.  In addition, the second apparatus separates the leading and trailing edge scrap so as to provide individual board panels which require no additional trimming.  As an alternative, two segmenting conveyors can be used in tandem so as to remove all of the scrap, thereby obviating the need for the first trim-scrap removing apparatus.

Abstract: Abstract of the Disclosure:   An optoelectronic assembly for converting a signal between optical and electrical form, or vice versa, consists of a dielectric substrate and a semiconductor substrate.  These substrates are fabricated separately and then brought together with major faces in intimate contact with each other.  The dielectric substrate has a pair of metallic electrodes on its surface and a waveguide extending to a coupling region.  The semiconductor sub-strate has an active optoelectronic device, e.g. a photodetector or light emitting device, whose optically active portion is brought into optically coupling relationship with the coupling region of the waveguide.          At the same time electrically contacting regions of the optoelectronic device are placed in electrical contact with respective ones of the pair of metallic electrodes on the dielectric substrate.  In addition to the advantage of separate fabrication of the two substrates, with consequent avoidance of the process incompatabilities that arise when trying to form optical and electronic elements on the same substrate, the invention is especially well suited to the formation of large scale integrated optoelectronic circuits and switching networks.

Abstract: ABSTRACT OF THE INVENTION         Mechanical stability and costing characteristics of structurally cation-active, film-forming latex, especially useful in electrodeposition coatings can be improved by the addition of small stabilizing amounts of linear cationic amine-modified epoxy resin having tertiary amine functionality and base number in the range of 30-500 and/or glycol mono-substituted ether alcohols.          "Stability" is defined by the absence of agglomerated latex particles as shown by disc centrifuge photosedimentometer traces after subjecting the latex to 30 minutes of mechanical shear using a Hamilton Beach mixer.  Such stabilized latex remains substanti-ally non-agglomerated even after being subjected to pumping and shear.  Without the stabilizer, agglomeration of the latex occurs.
