Title: Integrated temperature control/alignment system for high performance capillary electrophoretic apparatus
Inventor: KARGER BARRY L
IPC: F25B21/04
Filed: 1990-08-27
Abstract: ABSTRACT OF THE DISCLOSURE   An  integrated  temperature  control/alignment  system  for  use with  a  high  performance  capillary  electrophoretic  apparatus comprises  a  complementary  pair  of  capillary  column  mounting plates  formed  from  an  electrically  insulative,  high  thermal conductivity material for mounting a capillary column.  The first mounting   plate includes   a   well   having   a   predetermined circumference,  first and second grooves contiguous with the well and ports formed in the grooves and extending through the plate.          The  second  mounting  plate  includes  a  plug  configured  for insertion in the cell  and ports  aligned with the ports of the first mounting plate.   Respective ends of  the capillary column are seated and locked in the grooves to preposition the capillary column with respect to the ports.   Capillary columns of varying lengths may be mounted within the mounting plates by coiling the intermediate  portion  thereof  within  the  well  to  increase  or decrease  the  working  length  of  the  column  in  predetermined increments,  depending upon  the particular  application.   Optical coupling elements are disposed in the ports to couple sampling and  reference  radiation  to  and  from  the  mounted  capillary column.   The temperature of  substantially the entire capillary column  is  controlled  or  regulated by  at  least  one  thermopile disposed in thermal contact with one of the mounting plates.  A thermistor may be thermally coupled to the capillary column or one of the mounting plates to provide feedback signals to operate the   thermopile   to   maintain   the   capillary   column   at   a predetermined electrophoretic operating temperature.

Abstract: ABSTRACT OF THE DISCLOSURE          A method and apparatus for making snow by discharging a water spray at high velosity from a first nozzle positioned adjacent the top of a tower into a freezing ambient atmosphere and further discharging a jet stream of air under pressure into the throat of the water spray thereby forming a plume of atomized water. The efficiency and capabilities of snow making are enhanced by further discharging water under pressure into the atmosphere through at least one additional nozzle, positioned adjacent to the first nozzle, in the form of an additional spray which is directed into the plume. The additional nozzle may be above, below or beside the first nozzle and if two or more of the additional nozzles are provided, they may be positioned on the same side or on opposite sides of the first nozzle, and the supply of water delivered to the discharge nozzles need not be regulated for varying subfreezing temperatures. The snow tower is preferably rotatable about a vertical axis and is also preferably bent outwardly at an intermediate portion thereof to position the nozzles further away from the base of the tower to assist in regulated placement of the snow in varying wind conditions.

Abstract: SEALING SYSTEM FOR HERMETIC MICROCHIP PACKAGES                ABSTRACT OF THE DISCLOSURE        A    sealable   hermetic   microchip   package includes a  vent  therein that permits gas to escape during  the  sealing  operation,  but  then itself is sealed  at the completion of the sealing operation to render the  package  hermetic.    The venting of gas from  the  interior of the package avoids the buildup of  internal  pressure  during  the sealing operation that can introduce bubbles and other faults into the sealing  material.   The vent may be a channel in the sealing  surface  of  the  lid of the package that is initially   open,   and  then  fills  with  the  seal material  as  it  flows to effect the seal.  The vent may  also  be a hole in the lid that is sealed by the flow  of  a bead of the seal material.  An equivalent approach  to venting provides that the lid be mounted on  standoffs  that flow during sealing to permit the lid to settle onto the base of the package.

Title: Process for treating contaminated soil
Inventor: BATESON GEORGE F
IPC: B09C1/00
Filed: 1990-08-20
Abstract: A process for purification of soil contaminated with organic material is provided. The preferred process generally involves superposed attrition and classification processes, which lead to removal and concentration of highly contaminated fractions. The process may also include a step of flotation (61) whereby hydrophobic materials in the soil are released to an interface with air bubbles, and are floated to the top of a flotation cell. In preferred processes according to the present invention, soil to be treated is extracted from a contaminated site (11), and is broken into relatively small particles (12). These particles are preferably treated in attrition and classification steps (40), to remove fine, slow settling contaminated materials such as wood and fine soil materials. The resulting isolated coarser materials are then treated by flotation for a final polishing step. The process is particularly well adapted for use in treating soils contaminated with oil and grease materials containing PCP therein, from wood treatment plants or the like.
