Filed:

Feb 7, 2008

Appl. No.:

12/069304

Inventors:

Jerry Scott Reichert - Blodgett OR, US
Philip L. Chavez - Terrebonne OR, US
Wayne J. Traina - Albany OR, US

International Classification:

B60D 1/36

US Classification:

280477

Abstract:

A camper alignment system for use in guiding a pickup under a camper for loading of the camper uses a light source and a target for alignment. The pickup has a pickup cab and a pickup bed having a bed length. The camper has a camper front portion and a camper base. There is a light source capable of emitting a beam of light in the visible light spectrum when in operation. The light source is affixed on the camper front. There is a beam target disposed along the bed length. The beam target is substantially perpendicular with respect to the rear edge of the pickup bed. When the beam of light is substantially parallel to and projecting on the beam target, the pickup can be safely backed up toward the camper front portion and under the camper base for transport of the camper with the pickup.

International Classification:

B41J 2175

US Classification:

347 87

Abstract:

A disposable/refillable inkjet cartridge with bubble generator and an adhesively attached bubble generator vent cover. The cartridge is filed through a bubble generator opening in the cartridge bottom eliminating a separate filling orifice and easing the priming operation. The vent cover is adhesively attached making removal for refilling easier and avoiding suspected problems related to welding flash in welded vent covers. The bubble generator includes a tapered opening which receives a ball. The ball contacts ribs extending longitudinally along a tapered portion of the opening. The ribs are spaced over an arc of the opening. A bubble forms as needed between the ball and opening to maintain back pressure. The ribs and taper produce more consistent bubble pressures. A single piece of tape over the bubble generator and printhead nozzles avoids common causes for depriming.
