Patent CA-2416178-A1 (CA)
Inventor: FRICK BEAT
IPC: G03B27/32
Filed: 2003-01-13
Abstract: Optical representations of differing strip-shaped portions of an original are successively produced by way of an electro-optical converter operating pixel-by-pixel for the manufacture of a photographic print from an original present in electronic form. The optical representations are exposed onto the copy material in a strip-shaped exposure region, whereby the strip-shaped exposure region and the copy material are moved relative to one another at a constant speed and in a direction transverse to the longitudinal extent of the strip-shaped exposure region. In this way, the image information of the whole original is successively exposed onto the whole available surface of the copy material. A digital micro mirror array is preferably used as the electro-optical converter. The electro-optical converter is positioned in the exposure light path in such a way that its rows and columns extend at an angle of essentially 45E to the longitudinal extent of the strip shaped exposure region. A strip-shaped pixel region of the converter oriented essentially in the diagonal of the converter is thereby used for the production of the optical reproductions of the step-shaped portions of the original. Thus, the strip-shaped optical image representation of the strip-shaped portions of the original extend along the diagonal of the converter, which results in a higher resolution for the same converter since a larger number of pixels are available for production of the same image. Larger print formats can be achieved with commercially available converters and substantially without a loss in quality.

Title: Psa with adsorbents sensitive to contaminants
Inventor: BABICKI MATTHEW L
IPC: B01D53/06
Filed: 2001-12-11
Abstract: Disclosed embodiments address contaminant management challenges that arise during production of desirably contaminant free product fluid in the operation of PSA equipment, and further address the more serious challenges that arise under intermittent operation of PSA equipment. One embodiment includes a breather fluidly coupled to a feed end of an adsorber with a contaminant-sensitive adsorbent. The breather can be coupled to the feed end through a shutoff valve closed during production and open during shutdown. Other embodiments use particular sealing strategies for additional sealing of the apparatus, or at least components thereof, from contaminant ingress. For example, a buffer seal for receiving a buffer gas having a contaminant vapor content substantially the same as or less than a product gas produced by a pressure swing adsorption process over the adsorbers. As a second example, a parking seal can be used that typically is engaged when the apparatus is parked.
