Title: Inductor nozzle assembly for crop sprayers
Inventor: BURLS GARY E
IPC: B05B7/00
Filed: 1986-11-12
Granted: 1993-07-27
Abstract: Abstract of the Disclosure An inductor nozzle assembly for use with an air blast sprayer of the type having a tank holding waterborne pesticides, delivery lines connected to the tank and an air blast fan mounted in close proximity to the delivery lines, includes a spray nozzle mounted to the  delivery  lines  which  is  disposed  in  the  hollow interior of a conical-shaped housing mounted  thereto.          The housing is formed with an enlarged entrance opening, and a reduced diameter discharge opening which mounts an inductor ring charged with high electrical potential.  A high velocity stream of air produced by the air blast fan is directed into the housing through its entrance opening where  the  air  stream  is  accelerated  by  the conical  shape  of  the  housing  toward  its  discharge opening.  The waterborne pesticide supplied to the spray nozzle is ejected through the discharge orifice of the spray nozzle in a finely divided particle stream which is directed into the reduced diameter discharge opening of  the  housing,  charged  inductively  thereat  by  the inductor  ring  and  then  ejected  from  the  discharge opening by the high velocity air stream produced by the air blast  fan  for  deposition upon  the  trees  of  an orchard or other crops.  The stream of air from the air blast fan which is accelerated within the housing forms a barrier between the atomized particle stream and the inductor ring to maintain the inductor ring dry and at its full electrical potential.

Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus and method for moving a plurality of wafer-like articles such as semiconductor substrates back and forth between a carrier and a processing chamber maintained in an interior atmosphere isolated from that of the carrier.  A translating arm pivotal about its center with a wafer engaging vacuum chuck at each end loads and retrieves articles from the carrier and exchanges articles at a support.  The support centers an article thereon and translates it linearly to or from a load lock chamber.  The chamber opens and closes about the article on the support to maintain isolation of the environments as the article passes therebetween.  Within the interior atmosphere of the chamber, another arm pivotal at its center and having a vacuum chuck at each end exchanges articles on the support with still another arm, which is longitudinally rotatable and has a pair of vacuum chucks spaced both from a free end thereof, this arm being pivotal about its other end to move the articles in a horizontal plane, and then to rotate them to and from, and exchange them with, a vertical plane of the processing location.  At all other times, the articles remain in a horizontal plane.

Abstract: Abstract The  specification  describes a new and  improved thermal  ink jet printhead and fabrication process  therefor wherein  the  heater resistors are formed on one area of  an insulating substrate  and relative  large  area  electrical contacts  are  formed on an adjacent area of the  insulating substrate.   A  barrier layer is formed over the  conductive trace pattern defining the heater resistors on the one area, and  a small via in this layer provides an  electrical  path between  the large area electrical contacts and the  conduc-tive  track pattern,  and thus provides a current drive path for  the heater resistors.   The small via provides  minimum exposure  of the barrier sidewall area and area of the  con-ductive  trace pattern and thus improve device  reliability and fabrication yields and also improves electrical  contact to the printhead Alternatively,  the barrier layer may be made less than  laterally coextensive with the conductive trace mater-ial  to  thereby leave a small area of  the  trace  material available  for  metal overlay connection to the  large  area contact  pad  which is formed to the side of the  conductive trace material.

Abstract: ABSTRACT OF THE DISCLOSURE         A connector arrangement for electrically connecting circuit elements disposed on two printed circuit boards and spaced apart at centerlines of about 0.050 of an inch or less is described which includes a pitch controlling contact locator cooperating between the mating edge of an edge card and the connector housing.  The pitch controlling contact locator includes a resilient supported spring member disposed in the connector cavity generally at the midpoint of the terminal array which is resilient in a vertical direction and substantially rigid in a horizontal direction.  It further includes a mating cutout disposed in the mating edge generally at the midpoint of an array of contact pads which is adapted to engage the spring member with two points of contact when the edge card is inserted into the connector cavity.  The pitch controlling contact locator effectively reduces lateral mating misalignments introduced in the arrangement by stacking of manufacturing tolerances and vertical mating misalignments caused by mother board warpage introduced by exposure to high temperature wave soldering processing.

Title: Method and apparatus for conducting chemical reactions at supercritical conditions
Inventor: TITMAS JAMES A
IPC: B01J3/00
Filed: 1988-04-07
Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE A continuously flowing fluid is processed by being fed to the top of a hydraulic downdraft column (17) which is of a height such that the pressure at the bottom thereof will approximately be at the pressure necessary to create supercritical water conditions.  The fluid is conducted to the bottom of the column (17) and received in a reaction chamber (21) in which the majority of the fluid is recircu-lated around an annular baffle plate (24).  The material in the reaction chamber (21) is heated to a temperature above that necessary to create supercritical water conditions by an independent reaction taking place in a heating chamber (32).  The result is that the fluid will undergo chemical reactions at the supercritical temperature and pressure range and will be of a lower specific gravity than the unprocessed fluid.  The material not being recirculated in the chamber (21) is fed to one of two updraft columns (30, 31), a start-up column (30) used to preheat the material in the downdraft column (17) during initiation of the process, and a second column (31) isolated from the downdraft column (17) so as not to transmit any heat thereto during normal operation of the process.  The temperature of the fluid in the downdraft column (17) is thereby controlled to prevent decomposition of the material until the fluid enters the reaction chamber (21) at which time it is abruptly brought up to the supercritical water temperature.

Portions of the insulating layer 18 adjacent the impurity mask 21 are then removed, and P conductivity type impurity 33 is introduced into the substrate 15 except where it is protected by the impurity mask 21.  Finally, N-type impurity is intro-duced, also adjacent the impurity mask 21.  Then the structure is annealed, the impurity is diffused par-tially beneath the impurity mask to create a lateral SCR structure having a narrow PNP base width.
