  • Publication number: 20240091982
    Abstract: An automated wall frame assembly system for use in assembling a wall frame includes an advancer assembly including a conveyor system configured to transport first frame members along an assembly axis to an output of the conveyor system. A frame unit is disposed generally at the output of the conveyor system and is configured to receive the first frame members from the conveyor system and attach a second frame member to the first frame members. A gantry assembly is disposed above the advancer assembly. The gantry assembly includes a gantry frame and at least one gantry tool movably attached to the gantry frame. The gantry tool is operable to deliver the second frame member to the advancer assembly from a location above the advancer assembly for being attached to the first frame members.

  • Patent number: 11691342
    Abstract: A powder bed fusion apparatus for building an object in a layer-by-layer manner includes a build platform movable within a build sleeve to define a build volume, a layer formation device for forming layers of powder across the build volume in a working plane and an irradiation device for irradiating powder in the working plane to selectively fuse the powder. The powder bed fusion apparatus further includes a mechanical manipulator arranged to engage with the object and/or a build substrate, to which the object is attached, to tilt the object in a raised position above the working plane such that powder is freed from the object and deposited at a location above the working plane and/or into the build volume.

  • Patent number: 10428697
    Abstract: A fluid diverter including a cylindrical body and an extension arm is provided. The cylindrical body defines a first fluid passage extending from a first axial end of the cylindrical body and a second fluid passage circumferentially offset from the first fluid passage and extending from a second axial end of the cylindrical body. A seepage orifice is defined in the cylindrical body providing a fluid communication path between the first axial end and the second axial end. The extension arm extends from the cylindrical body and includes a locating receptacle dimensioned to receive a fixing element to rotationally and axially fix the fluid diverter.

  • Patent number: 10221729
    Abstract: A switchable valve train assembly including a carrier housing defining a hydraulic circuit, a supply assembly, a plurality of rocker shafts, a plurality of separators, and a plurality of rocker arm assemblies is provided. Each one of the plurality of separators divides the rocker shafts into (1) a first chamber extending between a first chamber axial end and the separator, and (2) a second chamber extending between a second chamber axial end and the separator. The plurality of separators each include an orifice defined between the first chamber and the second chamber that provides fluid connection between the first chamber and the second chamber. Locking assemblies of the rocker arm assemblies are selectively actuated based on the supply assembly. The separators ensure that hydraulic fluid within the hydraulic fluid is de-aerated and that the second chambers remain primed with hydraulic fluid for faster actuation of the locking assemblies.

  • Patent number: 9926816
    Abstract: A switchable rocker arm for valve deactivation is provided for a valve train of an internal combustion engine. The switchable rocker arm includes a cam lever assembly, a valve lever assembly, and a hydraulically actuated coupling assembly that is radially arranged between the cam lever and valve lever assemblies. The coupling assembly includes a shuttle pin, a locking pin with a round or flat locking interface, and optional shuttle pin and locking pin sleeves. In a first, locked position, the rotational motion of a camshaft is translated to linear motion of an engine valve. In a second, unlocked position, the cam lever assembly rotates about the valve lever assembly, facilitating valve deactivation. A pivot joint arranged between the cam lever and valve lever assemblies facilitates an arcuate lost motion of the cam lever assembly. An integrated arrangement for one or more lost motion springs offers packaging and functional advantages.
