Abstract: A vessel for the generation of synthesis gas at a high pressure, using hydrocarbons, includes a catalytic endothermic reforming section with a plurality of reformer tubes heated externally and filled with a catalyst, and a mixture of hydrocarbons and steam entering the reformer tubes which are positioned by a common plate. The reforming gas generated in the tubes flows from the tubed section into a partial oxidation section which has a larger diameter than the tubed section and the shape of a pressure vessel closed at one end, the free ends of the reformer tubes penetrating into the partial oxidation section, and in which inlet gas such as additional hydrocarbons and oxygen or oxygen-rich gas are mixed with the reforming gas. A plurality of inlet devices for the inlet gas are positioned in the cylindrical shell of the partial oxidation section with the axes of the gas flow streams being inclined away from the radial. The inlet devices are spaced a predetermined distance from the outlet end of the reformer tubes such that a rotary gas vortex is produced and the product gas stream flows through the outer section of the chamber, heats the reformer tubes and leaves the reforming section via an outlet nozzle.

Abstract: A hinged ski boot comprising a lower shell, continuous with an unsupported soft upper shell, forming one continuous compound shell. The rigid lower shell has a forwardly located reinforced area for engagement of the front ski binding and a control linkage.      The lower rigid shell has a recessed rearwardly located reinforced area for engagement of the rear ski binding and shaft hinges. A skeletal shaft, front cuff and rear cuff form one continuous portion, devoid of fastening means and is hingedly secured to the lower rigid shell.      A tubular control linkage connects the front of the rigid shell to an intermediate portion of the shaft.      This control linkage provides both forward and rearward flex control, provides flex progressiveness, provides a flex biasing, limits maximum ankle movement, provides forward-lean adjustment and comprises a piston air pump, actuated by ankle flex, to draw cold stale air from the front of the shell cavity.      The combination of a rigid lower shell and a non supported soft upper shelf reduces unwanted air invasion into the shell cavity and provides a non critical shaft hinge location.      The structure of the ski boot is both weight efficient and energy efficient.

Abstract: A device and method for permitting the separation of plasma or serum from whole blood. The device comprises a matrix of hydrophilic sintered porous material to which at least one red blood cell agglutinating agent has been applied. According to a first method of using the device, a sample of whole blood is applied to a first end of the matrix and the red blood cells within the sample come in contact with the agglutinating agents present in the matrix. The blood cells agglutinate, and are entrapped in the interstices of the matrix, while substantially blood-cell-free serum or plasma accumulates near the outlet of the device. A filter means in liquid receiving relationship with the matrix functions to wick the serum or plasma from the matrix.        According to an alternative aspect of the invention, a filter means in liquid receiving relationship with the outlet of the matrix functions to retain any blood cells which pass through the matrix as the filter means wicks the plasma or serum from the matrix. Additional agglutinating agents may be incorporated within the filter means to facilitate retention of blood cells which pass through the matrix.      Another aspect of the present invention involves a device for the measurement of a serum or plasma sample, utilizing a matrix of sintered porous material, such as sintered glass, sintered steel, sintered ceramics, sintered plastics, and equivalents thereof. The matrix is characterized by a reproducible fluid uptake capacity proportional to the fixed dimensions of said matrix, a minimal reactivity with plasma or serum components, and a hydrophilic internal surface which enables the matrix to collect and retain a predetermined volume of sample for analysis.      A further aspect of the present invention provides a porous reagent delivery system comprising a matrix of sintered porous material containing at least one reagent in a freeze-dried state, and method for making same. The system allows the delivery of a unitized form of a freeze-dried reagent which is recoverable upon contact with a liquid.

Title: Method for enhancing the uniformity and consistency of dot formation produced by color ink jet printing
Inventor: TRASK JEFFREY L
IPC: G06K15/10
Filed: 1990-06-19
Granted: 1996-03-26
Abstract: A multiple pass complementary dot pattern ink jet printing process for enhancing the uniformity and consistency of dot (drop) formation during color ink jet printing.  Such enhancement in turn directly affects and improves the total print quality over a color printed area by minimizing the undesirable  characteristics  of  coalescence,  beading,  hue shift, banding, cockeling and color bleed when printing on both transparencies and plain or special papers. Using this process,  successive printed swaths are made by depositing first and  second partially overlapping complementary dot patterns on a print media.  Simultaneously, the dot spacing in coincident dot rows within the overlapping portions of the dot patterns is alternated between dots in the first pattern and dots in the second pattern.  This invention is also directed to the novel process of combining complementary pass ink jet printing as described above with dot-next-to-dot (DND) super pixeling in order to further optimize the ink drop drying conditions  desirable  for  producing  the  above  optimized uniformity and consistency of dot formation over a given color printed area.

Abstract: Application  of  substantial  pressure to ends of a frankfurter. concurrent with passing of electrical current, through the  application of  a cooking tray whose structure accepts multiple frankfurters and allows the pressure to be applied  by  the  use  of  a  carriage system with multiple plungers whose  points  of  contacts  serve  as electrodes; use of aluminum foil patches between the extremities of the frankfurter and electrode plunger cups is  made to maintain conductivity  with  said  aluminum patches being applied by use of a paper tape sprocket system which is microprocessor controlled  or   in  the  alternative  by  manual  operator insertion in a modified  cooking tray  which eliminates the need  of  the  paper  tape sprocket system.  Application of pressure to  extremities  of  the  frankfurter  is  well in excess of that required for mere electrical contact, but is part of  the  cooking  process  for  producing  a processed frankfurter in  less than  40 seconds with high reliability by passing an electric  current without  burning or arcing.          Within the frankfurter, the substantial pressure eliminates voids and  provides a  consistent electrical  contact.  The apparatus  allows   for  the   use  of  various  brands  of frankfurters in as much as a  consistent uniform electrical contact  is  provided  by  the  use of a combined specially shaped plunger which also serves as part of the electrode.
