  • Patent number: 9638374
    Abstract: A method is provided for verifying integrity of a recirculation valve in a recirculation line of an LNG dispenser. The method includes: closing the recirculation valve and a fill valve in a supply line that supplies LNG; monitoring a mass of the LNG flowing through the recirculation line to ensure that the mass flowing therethrough is less than an acceptable threshold; and aborting any pending sales if the mass of the LNG flowing therethrough is not less than the acceptable threshold. According to another embodiment, a method is provided for verifying integrity of a vent valve in an LNG dispenser. The method includes: closing the vent valve and opening a fill valve in a supply line that supplies LNG; monitoring the pressure of the LNG within the fill hose to ensure that the pressure remains steady; and aborting any pending sales if the pressure does not remain steady.

  • Patent number: 9625026
    Abstract: A locking differential assembly includes a differential case defining an axis of rotation and a gear chamber. A first side gear is at a first end of the differential case. A second side gear is at a second end of the differential case opposite the first end for selectable rotation relative to the differential case. At least two pinion gears are rotatably supported in the gear chamber in meshing engagement with the first side gear and the second side gear. A solenoid is at the first end. A plunger is selectably magnetically actuatable by the solenoid. A lock ring is selectably engagable with the second side gear to selectably prevent the side gear from rotating relative to the differential case. At least two relay rods are each connected to the plunger and to the lock ring to cause the lock ring to remain a fixed predetermined distance from the plunger.

  • Publication number: 20160168401
    Abstract: Disclosed are aqueous inkjet inks containing a polymeric ink additive as a binder. The binder contains a component capable of interacting with cellulose. Certain acrylate monomers having similar Hansen solubility parameters as cellulose were incorporated into the polymeric binders. Prints from these inks have better durability than similar additives that do not have the components capable of interacting with cellulose.

  • Publication number: 20160147153
    Abstract: Systems, devices, and methods for printing on surfaces of three-dimensional objects are provided. The systems, devices, and methods allow for images, and three-dimensional structures, to be printed onto a surface of a three-dimensional object. The surface of the three-dimensional object can have many different shapes, including an arbitrary or non-uniform shape having multiple curves. In one exemplary embodiment, the method includes associating a pattern of polygons with a surface of a three-dimensional object and then scaling a pattern of polygons associated with an image to be printed onto the surface with the pattern of polygons associated with the surface. One or more polygons of the scaled pattern of polygons are then progressively projected onto the surface, and a photosensitive material associated with the surface is cured to set projected image portion on the surface. Systems, devices, and other methods for printing onto surfaces of three-dimensional objects are also provided.
