Abstract: An in line fluid filter has an elongate tubular housing with end fittings. An axially disposed closed elongate cylinder is held within the housing defining an annular fluid chamber therebetween. The annular fluid chamber is divided into a plurality of concentric, parallel annular flow paths by at least one elongate concentric, fluid impermeable partition. The flow paths are occupied by a woven wire filter fabric with coarse mesh. This provides a long tortuous filter path that does not readily clog up and that prevents the passage of large particles.

Abstract: An inkjet printer with multiple printheads in a carriage divides service station functions between a first service station and a second service station. In a preferred embodiment, a black ink printhead is carried by the carriage to a stop position in the first service station where a wiper dedicated to the black ink printhead moves across a stationary nozzle array in a first wiping procedure, and color ink printheads are carried by the carriage to a second service station to move a nozzle array across stationary wipers respectively dedicated to each color ink printhead. The first service station provides spittoon services to all printheads, and the second service station provides capping as well as priming services to all printheads.

Abstract: An inkjet printer has a printhead mounted in a carriage which periodically moves along a printhead path in a carriage scan direction to a stop position in a service station where an actuation device imparts translational motion to a wiper blade. The wiper blade moves along a linear wiping path orthogonal to the printhead path and across ink orifices on a nozzle surface of the printhead during a wiping operation. The wiper blade is removably mounted on a base and is split to form a first blade for wiping one column of ink orifices and a second blade for simultaneously wiping another column of ink orifices on a nozzle surface of the printhead. In a preferred form of the invention, the service station provides different sequential wiping steps with successive wiper blades by first drawing ink onto the nozzle surface from the ink orifices with a rounded blade edge of a leading wiper blade, and then wiping the ink from the nozzle surface with a sharp blade edge of a following wiper blade.

The display is constructed and arranged such that the image is viewable from first and second sides (116, 118) of the display, the first and second sides facing opposite one another.

Abstract: An inkjet printer has a printhead mounted in a carriage which periodically moves in a carriage scan direction to a stop position in a service station where an actuation device causes a wiper blade to move back and forth across ink orifices on a nozzle surface of the printhead during a wiping operation. The actuation device incorporates a rotating lead screw to impart transtlational motion to the wiper blade in a wiping direction orthogonal to the carriage scan direction. A clutching action prevents further movement of the wiper blade after completion of each wiping step. The actuation device is driven through a gear train from a motor such as a media advance motor. An ink spittoon is incorporated in the same service station for receiving ink generated during a spitting operation, and a scraper in the ink spittoon removes residual ink from the wiper blade.

Abstract: An ink-jet printer having a dual drying system. A print heater is disposed at the print zone for heating a portion of the print medium during printing operations to dry ink ejected onto the medium. The printer has means for drying the print medium at a drying location before the medium reaches the print zone to prevent uneven shrinkage of a cellulose-based print medium due to heating the medium at the print zone. The print heater can be controlled to provide a higher temperature at the print zone than the drying means provides at the drying location. The printer provides the capability of independent control of said drying means and said print heater.

Abstract: A gun lock utilizes an internal combination wheel which is advanced by the pressing of combination buttons which urge a combination wheel toward an unlock position. The unlocking of the gun lock enables a spring loaded rachet to be springingly urged quickly out of engagement with a main housing of the gun lock to enable the gun to be readily fired. The combination is set by the orientation and radial positioning of a series of angled blocks supported by the combination wheel. The combination setting for each advanced position of the wheel is based upon the combination wheel's position resulting from the prior movement in executing the previous combination number.

Abstract: A color ink-jet printer having a heating blower system for evaporating ink carriers from the print medium after ink-jet printing. A preheat drive roller engages the medium and draws it to a print zone. The drive roller is heated and preheats the medium before it reaches the print zone. At the print zone, a print heater heats the underside of the medium via radiant and convective heat transfer through an opening pattern formed in a print zone heater screen. The amount of heat energy is variable, depending on the type of the print medium. A crossflow fan at the exit side of the print zone direct an airflow at the print zone in order to cause turbulence at the medium surface being printed and further accelerate evaporation of the ink carriers from the medium. An exhaust fan and duct system exhausts air and ink carrier vapor away from the print zone and out of the printer housing.

Abstract: A fiber spray system for depositing fibers onto a substrate or article comprises a vibrating feeder bowl having an opening in its sidewall covered by a grid or screen through which fibers loaded into the feeder bowl are discharged therefrom into the fiber collector. A delivery hose is connected between the fiber collector and a pump which is operative to create a negative pressure within the fiber collector to draw fibers through the grid of the feeder bowl, out of the feeder bowl into the fiber collector and to entrain the collected fibers within a stream of air. The air-entrained fibers are drawn through the delivery hose to the pump, and in the course of passage therethrough the velocity of the fibers is reduced so that they collect or accumulate within an area in the delivery hose upstream from the pump. The pump uniformly withdraws fibers from the area where they accumulate and discharges the fibers directly into a spray gun connected to the pump for deposition onto a substrate.
