International Classification:

US Classification:

395102

Abstract:

A system for providing an output from a digital printing apparatus which is of higher resolution than the native resolution of the original image data. For a given center pixel area, image data corresponding to pixel areas generally neighboring the center pixel area are attempted to be matched to various templates which are consistent with curved lines in which resolution enhancement of the center pixel would be desirable. In a second stage of template matching, a second set of image data, corresponding to pixel areas further away from the center pixel than the first set of pixel areas, is also attempted to be matched to templates. The second stage of template matching helps to avoid resolution enhancement of image data which is related to a halftone image.

Assignee:

Val Products, Inc. - Bird-in-Hand PA

International Classification:

F24F 1300

US Classification:

454270

Abstract:

A ventilation control system is disclosed for a building having an elongated ceiling vent opening, the system having a vent door, spaced apart brackets pivotally supporting the door on the building structure adjacent to the ceiling vent opening such that the door is movable between closed and opened positions, and an actuating mechanism for moving the door between the closed and opened positions. The vent door has an elongated door casing of plastic material having a hollow interior and opposite side walls, a support member located in the hollow interior of the door casing adjacent to each of the opposite side walls and a foam material substantially filling the hollow interior of the door casing. The door casing may be extruded from plastic material and has integrally formed outwardly extending sealing members which engage the building structure when the vent door is in the closed position to seal the vent opening. The support members have connecting portions extending from one end of the door casing to facilitate connecting a plurality of doors together in end-to-end abutting relationship.

International Classification:

A01K 7/02
B05B 1/30
B05B 3/02
B05B 12/08

Abstract:

A pressure regulator for controlling flow of a fluid therethrough is provided. An upper housing member and a primary diaphragm define an upper chamber and a lower housing member and the primary diaphragm define a lower chamber. The pressure regulator further includes: a valve assembly provided within the upper chamber for controlling the flow of the fluid from an inlet body into the upper chamber; a secondary diaphragm provided within the lower chamber and defining a secondary diaphragm driving chamber; and a passageway connecting the inlet body and the secondary diaphragm driving chamber. During operation, the secondary diaphragm driving chamber is filled with the fluid at the inlet pressure, thereby subjecting the secondary diaphragm to the inlet pressure and generating the force for actuating the valve's disengagement from the inlet body. The pressure regulator functions to maintain the outlet pressure at a value that is a predetermined fraction of the inlet pressure.
