| 20090077937 | COLLAPSIBLE FILTER WITH FOLDING ARMS - The present invention addresses the need for a collapsible filter that is easily assembled and installed. The collapsible filter comprises top and bottom arms rotatably attached to the top and bottom edges of two end caps. A pleated filter media is provided attached to at least one of the end caps. The present invention also addresses the need for mechanisms to facilitation the expansion of the pleated filter media, utilizing spring-like devices or other materials that may be compressed but expand to a natural state. Similarly, the present invention further addresses the need for mechanisms that allow for controlling the distance between adjacent pleats within a pleated, collapsible filter media. The present invention recognizes that a combination of these approaches may be utilized to provide a collapsible filter that is easily constructed at a manufacturing facility, assembled in the field, and installed within a system having need for a filter. | 03-26-2009 |
| 20090145060 | FRAME FOR RECEIVING A FILTER ELEMENT AND METHOD FOR PROVIDING - A frame for receiving a filter element includes: a pair of first members and a pair of second members. The first members may be arranged alternately with the second members in the assembled orientation to establish a plurality of joining structures between adjoining members. Each respective joining structure of the plurality of joining structures maintains the adjoining members oriented substantially about a respective axis. The first members and the second members cooperate to define a volume for effecting the receiving. | 06-11-2009 |
| 20100106309 | GENERAL CONTROL TECHNIQUES IN A HEATING, VENTILATION AND AIR CONDITIONING NETWORK - The disclosure provides an HVAC data processing and communication network. In various embodiments of systems and methods including a bus, a compressor is coupled to the bus, and a subnet controller is coupled to the bus. The subnet controller disables the compressor when acting upon a dehumidification command. | 04-29-2010 |

The print head cover includes a face and a print opening disposed in the face. The print opening disposed adjacent an ejection point of the print head. A perforated area is disposed on the face. | 08-19-2010 |
| 20100220149 | INK JET MODULE - A core module for an ink jet printer includes a housing and a connection manifold disposed on the housing and including a plurality of ports providing fluid communication into and out of the module. A plurality of components is disposed within the housing, including a filter module, an ink reservoir, and an ink circuit. The filter module includes a fluid filter disposed in a filter housing. The filter housing has an inlet and an outlet. The ink circuit is in fluid communication with the components and the ports, and includes fluid paths for conveying ink between the components. The filter module is connected to the connection manifold such that the filter housing inlet and outlet are each in fluid communication with one of the plurality of ports on the manifold. | 09-02-2010 |
| 20100238212 | ELECTROMECHANICAL CONVERTER FOR INK JET PRINTING - A method of driving an electromechanical converter of a print head of a continuous inkjet printer, wherein the electromechanical converter is arranged to break up a continuous stream of ink into a plurality of drops. The method includes determining a modulation voltage to drive the electromechanical converter, at least a property of the modulation voltage being controlled to take into account movement of a break up point of the continuous stream of ink, and to ensure that in a characteristic of modulation voltage versus a property at least indicative of a break up point of the continuous stream of ink, the characteristic has a predetermined gradient, or a gradient related to this predetermined gradient; and driving the electromechanical converter at the determined modulation voltage. | 09-23-2010 |
| 20110032298 | PRINTING METHOD - A method of printing an image on a substrate effected by moving the substrate past a print head during a printing operation and printing the image by printing a plurality of strokes. Printing each stroke includes emitting a plurality of drops of ink from the print head. The method includes receiving image data defining an image to be printed, the image data including data relating to a characteristic of the image; selecting printer control data defining the plurality of drops of ink which are to be emitted from the print head to print a stoke, the selecting being based upon data indicating a maximum number of drops of ink which can be emitted from the print head during a stroke and the characteristic of the image; and printing the image based upon the data defining the image to be printed and the printer control data. | 02-10-2011 |
| 20110037814 | INK SUPPLY SYSTEM - An ink supply system for an ink jet printer, particularly a continuous ink jet printer, has a manifold assembly of two parts that are brought together at interfacing surfaces. At least one of the surfaces has a plurality of ink flow channels for conveying ink around an ink circuit between components. The other of the interfacing surfaces is configured to close and seal the channels. A plurality of ports is provided in fluid communication with the channels, the circuit components being connectable to the ports. The manifold assembly provides for a compact and neat arrangement free of many tubes and pipes. The lower number of connections significantly reduces the risk of leakage. | 02-17-2011 |
