Title: Ink jet printing using elongated pixels
Inventor: TEMPLE STEPHEN
IPC: B41J2/045
Filed: 2003-09-01
Abstract: An ink jet or other printer serves to print for each row of input pixels, two superimposed rows of contiguous "super pixels", each print pixel being capable of receiving print contributions from N super pixels. The super pixels are twice the width of the input pixels and one row of super pixels is offset by half a super pixel width from the next row of super pixels. Redundancy is thus provided against the loss of a print element. The effects of smoothing of an image are reduced by edge enhancement processes.

Patent CA-2498359-A1 (CA)
Inventor: NIEDERREITER JOHN F
IPC: F28D19/04
Filed: 2005-02-24
Abstract: Frosting and fouling are two of the most prominent concerns regarding heat exchangers, in particular, regarding heat exchange between hot and cold air flows for building ventilation. Frosting and fouling both cause a build up of material on heat exchange surfaces thereby increasing the thermal exchange resistance between the hot and cold air flows.  This document defines a heat exchanger that is based on the heat sink principle, like the heat wheel and reverse flow exchangers. However it differs from these in that the thermal mass or heat sink is a continuous body that passes through each fluid successively, parallel and counter to each fluids' direction of flow. This configuration continuously melts the frost that has formed on the heat sink surfaces. In addition, because of its continuous nature and movement, the heat sink surfaces may be continually scraped clean by strategically placed scrapers
