Abstract: A valve having a metal insert with a fluid passage formed in the metal insert. A composite valve body is disposed at least partially around the metal insert and having at least one port in fluid communication with the fluid passage with the metal insert. A valve member is partially disposed in the metal insert and operable to control the fluid flow through the fluid passage of the metal insert and parts of the valve body.

Abstract: A three-dimensional printing system includes a build plate, a carriage, a housing assembly covering the carriage, and a printhead. The build plate includes a lateral print area having a length along an X-axis and a width along a Y-axis. The carriage has a major axis along the Y-axis that spans the width of the lateral print area. The printhead is mechanically, fluidically, and electrically coupled to the carriage. The printhead includes a printhead housing that cooperates with the housing assembly to separate a print zone containing the lateral print area from connected internal components of the printhead and the carriage. The carriage is configured to scan along the X-axis and the printhead is configured to scan along the Y-axis supported by the carriage to address the entire lateral print area.

Abstract: In an aspect of the disclosure, a three dimensional (3D) printing system includes a printhead and an ink supply subsystem. The printhead is for ejecting drops of phase change ink to define a three dimensional article of manufacture. The ink supply subsystem includes an ink tube, a helical resistor, a return conductor, and an outer tube. The ink tube has an inside surface for contacting and transporting the phase change ink and an outer tubular surface. The resistor is helically wound around the outer tubular surface of the ink tube. The return conductor is helically wound around the resistor and has a resistance that is lower than that of the resistor. The outer tube surrounds and protects the resistor and the return conductor and provides insulation to the heated ink transport component.

Abstract: Methods and systems of dynamic comment are provided. A comment library stores comment entries and provides a basis for determining comment selections dynamically. Metadata associated with the comment entries may also be stored in the comment library. A set of comment selections may be determined based on the context in which a user is commenting on the digital content and the user's input. A comment library may be searched for matching instances of the user's input to determine the set of comment selections.

Abstract: A solenoid actuated valve (10) holds pressure and volume of an accumulator with low leakage and provides low actuation drag during a release stroke for dumping fluid contents of the accumulator at very low current draw. Two elongate valve members (10a, 10b) are assembled to be movable axially relative to one another with a gland or groove (10c) formed in one of the two valve members (10a). An o-ring (12) located within the groove (10c) is in a non-contacting relationship to the other valve member (10b) when in a non-energized state. An energizer ring (14) located within the groove (10c) can reciprocate axially with respect to the o-ring (12). The energizer ring (14) moves axially toward the o-ring (12) in response to fluid pressure against a surface (14a) of the energizer ring (14) opposite from the o-ring (12) to axially compresses the o-ring (12), causing the o-ring (12) to expand radially outwardly into sealing contact with the other valve member (10b).

Abstract: A 3D printing system comprises an X-axis base for positioning stationarily relative to movable Y-axis and Z-axis components. The X-axis base has first and second sides and a workpiece opening. A Z-axis base is secured to the X-axis base's second side adjacent the opening. The Z-axis base is configured to support a model being printed and to controllably move the model in a Z direction through the opening. There is a movable arm member slidingly coupled to the second side of the X-axis base and extending over the first side of the X-axis base. The movable arm is movable in an X direction. A Y-axis carriage is slidingly coupled to the movable arm member and is movable in a Y direction. A printhead coupled to the Y-axis carriage is controllably movable in the X and Y directions to print successive layers of the model supported by the Z-axis base.

Abstract: A hydraulic valve assembly (10) adapted to be mounted to a transmission control module (15) and having a valve body (12), a valve bore (16), and at least one pressure supply port (26) as well as at least one pressure control port (28) that establish fluid communication between a source of pressurized fluid and a component to be controlled by the valve assembly. A valve member (18) is supported in the valve bore (16) and is selectively movable between predetermined positions to direct the pressurized fluid between the pressure supply port (26) and the pressure control port (28). In addition, the hydraulic valve assembly (10) includes a biasing mechanism (80, 180, 280, 380) that is responsive to the flow of hydraulic fluid through the valve body to generate a biasing force acting on the valve body (12) in a direction toward the pressure supply port (26).

Abstract: In a preferred embodiment, the present solenoid control valve is provided which has a valve sleeve having upper and lower feedback chambers which are connected to control pressure by an exterior surface longitudinal slot or slots.
