A method for reordering the pixel map of a multi-dimensional image by representing each pixel address as a unique set of coordinates in binary reprsentation, reversing the bit order for each coordinate, interleaving the binary digits of the numbers thus formed from each coordinate in a consistent bit-by-bit fashion, and using the composite binary number thus formed as a new pixel sequence number; storage and/or subsequent transmission of pixel values then takes place in order of ascending pixel sequence numbers, omitting numbers representing pixels outside the limits of the selected image.

Method for reordering the pixel map of a digitized image

There is disclosed an improved PSA process and apparatus for gas enrichment wherein the pressure levels of the vent gas stream and/or product stream are used to drive gaseous diffusion cells to produce a feed gas stream and/or a purge gas stream to be used in the pressure swing adsorption process to increase on-line production time and to utilize the waste pressure energy thereby decreasing energy requirements per unit of production.

PSA process and apparatus employing gaseous diffusion barriers

There is disclosed a process and apparatus for gas enrichment utilizing pressure swing adsorption techniques wherein the compressed gaseous mixture being processed is passed in indirect heat transfer relationship to a bed of adsorption material in an adsorption vessel undergoing regeneration wherein the heat of compression is employed to improve regeneration of the bed of adsorption material during the desorption step prior to passing the compressed gaseous mixture through a cooling system and thence through a bed of adsorption material for gas enrichment at a lower, more efficacious adsorption temperature.
