Abstract: Un récipient tubulaire destiné à être ouvert pour permettre lors de la culture, la mécanisation du remplissage et de l'ensemencement, lorsque le récipient est ouvert et dans une position substantiellement horizontale et pour assurer la protection des tiges. Le récipient comprend: deux parties semi-cylindriques. Chacune des parties possède à une première extrémité définissant la partie supérieure, un cloisonnement semi-circulaire avec orifice axial semicirculaire, chaque cloisonnement définissant la partie supérieure ayant une paroi débordante semi-circulaire, chacune des parois débordantes se fondant dans la partie du cloisonnement semi-circulaire formant l'orifice semicirculaire. Chacune des parties à l'autre extrémité a un cloisonnement substantiellement semi-circulaire définissant le fond et chaque cloisonnement a un orifice axial semicirculaire. Le rayon de la paroi débordante est plus petit que le rayon des orifices semi-circulaires du fond. Ainsi lorsque plusieurs récipients sont ouvert et dans une position horizontale, la paroi débordante d'une des partie semi-cylindrique d'un récipient peut télescoper dans un orifice semi-circulaire du fond d'une des parties semicylindriques d'un autre récipient, de manière à ce que les cloisonnements respectifs définissant la partie supérieure de l'un des récipients et le fond d'un autre récipient adjacent au premier soient en étroite proximité l'un de l'autre, et ainsi permettre le remplissage automatique des récipients sans gaspillage de remplissage. Les parties semi-cylindriques de chaque récipient sont pivotablement joint le long d'une bord d'une des parties semi-cylindriques au long de l'un des bords de l'autre partie semicylindrique, pour former un récipient substantiellement cylindrique et ayant une cheminé définie par les parois débordantes.

Title: Source of high flux energetic atoms
Inventor: CALEDONIA GEORGE E
IPC: H05H3/00
Filed: 1987-08-19
Granted: 1991-03-19
Abstract: ABSTRACT        Method   and   apparatus    for   generating   a   nearly mono-energetic  beam  of  atoms  at  velocities  on the  order  of several   km/sec   (energies   of   1-10eV)   and   for   achieving modification of the surface properties of a target by the beam, including  surface  erosion,  reaction  with  the  beam  species, cleaning  and  coating,  all  over  a  large  area.   A  gas  or  gas mixture  is  forced  through  a  nozzle  throat  into  a previously evacuated expansion nozzle resulting in the acceleration of the gas  in a confined flow.  Laser radiation is applied to the gas flow  to  cause  breakdown  and dissociation  of  the gas  into  an atomic plasma.  The plasma is allowed to expand within the nozzle cone reaching a high velocity in the desired range.  The beam is generated within a vacuum chamber to maintain the purity of the gas components and prevent collisional effects.  The beam is used to modify the properties of a target material placed in the path of its flow and its atoms may react with surface components to form  a  molecular  coating.   By  applying  the  gas  in  pulses, controlled thin layering,  even to the extent of a single atom thickness, is possible.

Title: Process of preparing a preferred ferric sulfate solution, and product
Inventor: HJERSTED NORMAN B
IPC: C01G49/14
Filed: 1987-11-16
Granted: 1991-07-23
Abstract: PROCESS OF PREPARING    A PREFERRED FERRIC SULFATE SOLUTION, AND PRODUCT                 Abstract of the Invention A process is provided for preparing a preferred ferric sulfate solution.  The product of the process is particularly suited for use in water treatment and purification.  According to the process, iron oxides or iron, are dissolved in sulfuric acid to form ferrous sulfate.  In a first step of oxidation, the ferrous sulfate is partially oxidized to ferric sulfate in the presence of dissolved oxygen.  In a second stage of oxidation, remaining ferrous sulfate is oxidizing to ferric sulfate by the action of a non-molecular oxygen oxidizing agent such as hydrogen peroxide.  During both stages of oxidation, a catalyst such as copper sulfate or copper ammonium sulfate may be used.          Careful control of added sulfuric acid is maintained, to avoid excess or free sulfuric acid in the reaction product.          The final reaction product is generally characterized by having:  between about 10% and 12% iron by weight; substantially all iron present in the ferric form; and, by having less than 0.5% free or excess acid, by weight.

Title: Intracavitary ultrasound scanner means
Inventor: HETZ WALTER
IPC: G10K11/00
Filed: 1987-12-03
Granted: 1992-07-14
Abstract: ABSTRACT OF THE DISCLOSURE A first ultrasound transducer (24) is mounted in the interior of an examination head (4), which is rotatable around an axis (26) by means of first and second gears (52, 56) and by means of a drive shaft (22) which is driven by an electric motor (106) for scanning a first examination surface.  The axis (26) is aligned perpendicular to the distal end of the drive shaft (22).  The two gears (52, 56) are preferably fashioned as bevel gears.  The second gear (56) is secured to the end of the drive shaft (22) and has a depression (60) into which the first ultrasound transducer (24) passes when it turns.  A compact structure is achieved in this way.  A second ultrasound transducer (90) is secured to the second bevel gear (56), which turns around the drive shaft (22) and thereby scans a second examination surface having the shape of an envelope of a cone which is positioned not entirely perpendicular relative to the first examination plane.  Both transducers (24, 90) are rotatorily driven by the same drive shaft (22), which results in a simple design.  The device is particularly suitable for vaginal and rectal examinations.

Title: Processes for decontaminating polluted substrates
Inventor: MAZUR DUANE J
IPC: B09B3/00
Filed: 1988-03-28
Granted: 1996-01-09
Abstract: Various solid/porous substrates, including soil, clay, sand, stone; articles of manufacture, such as transformers  and  other  hardware  items,   and  liquid substrates,  such  as  dielectric  fluids,  and  the  like, contaminated with potentially toxic organic compounds are decontaminated and recycled for further use by treating with solvated electrons either at the situs of the toxic spill or by batch treatment in a reactor.  The process can utilize solvated electrons prepared chemically or electro-chemically.    Advantageously,  substances  such  as  water believed to compete with the selectivity between solvated electrons and the toxic substance or interfere with the stability of solvated electrons need not be removed from contaminated  substrates.     Other  embodiments  of  the invention include methods of treating porous substrates with chemicals for solubilizing the toxic material for more efficient elevation of contaminates especially from porous surfaces.  The methods of the invention are also especially useful in the destruction of bulk quantities of CFCs known to be harmful to the earth's ozone layer.

Abstract: Abstract of the Disclosure A sheet including a layer of flexible polymeric material having a coating of repositionable pressure sensitive adhesive on a second end portion that is generally transparent when adhered to a substrate, while being free of adhesive along a visually distinctive first end portion. A pad of the sheets in a stack with adjacent ends of the sheets aligned and with the first and second ends of successive sheets adjacent can be disposed in a chamber partially defined by a top wall having a slot through which the first end portion of the uppermost sheet projects. Relative movement is afforded between the top wall and the uppermost sheet to afford, as the uppermost sheet is pulled through the slot, alignment of the slot with successive portions of the uppermost sheet toward its second end as those successive portions are peeled from the stack. In a final relative position between the top wall and the uppermost sheet the slot is along the second end portion of that sheet and the first end portion of the underlying sheet to cause movement of the first end portion of the underlying sheet through the slot with the second end portion of the uppermost sheet to leave the first end portion of the underlying sheet projecting through the slot after the uppermost sheet is removed.
