摘要:
An obstruction detection device for use with a truss fabrication system including a table having spaced accessways. The obstruction detection device includes a support structure configured for movable attachment to a table having spaced accessways. An obstruction sensor is connected to the support structure and configured to detect obstructions in the spaced accessways of the table. The obstruction sensor has an activated state and a deactivated state. A control system is operatively connected to the obstruction sensor to activate and deactivate the obstruction sensor in response to a position of the obstruction sensor relative to the spaced accessways. The control system activates the obstruction sensor when the obstruction sensor is aligned with one of the spaced accessways of the table and deactivates the obstruction sensor when the obstruction sensor is out of alignment with the spaced accessways of the table.

Monolithic metal bodies (e.g., hard aluminum alloys) comprising a continuous microcavity contained within the body are disclosed. The ratio of the cross-sectional area of the metal body to the cross-sectional area of the microcavity may be not greater than 10. The produced metal bodies may be used in structural applications (e.g., aerospace vehicles) to monitor or test the integrity of the metal body.

A door lock striker alignment check fixture includes a check fixture body having a tapered region engageable with a striker receiving slot of a door latch mechanism. The check fixture body defines an elongated slot for receiving a door striker. The door lock striker alignment check fixture further includes a flange fixedly attached to the check fixture body, and which is engageable with an exterior surface of a vehicle door coupled to the door latch mechanism. The flange includes a contact surface that contacts the exterior surface of the vehicle door and which faces an insertion direction of the tapered region with respect to the striker receiving slot.

A method and apparatus for providing a stackable hard-disk drive (“HDD”) carrier using pull-out drawers and fasteners are disclosed. The carrier, in one embodiment, includes an inner case or drawer and an outer frame casing. The inner cage includes a base plate, a front cover, a first side panel, and a second side panel, wherein the first and second side panels are hinged to the base plate. The inner cage is configured to house a removable HDD. The first and second side panels also include fasteners for securing the HDD to the inner cage. The outer frame casing is configured to receive the inner cage via its two opposite guiding walls. The guiding walls are configured to allow extending the inner cage to a predefined distance from the outer frame casing for accessing the HDD.
摘要:
A first structural static component having an outer diameter is aligned with a second structural static component having an inner diameter to the centerline of a gas turbine engine rotating assembly. The first static component is centered inside the second static component leaving a gap between the outer diameter of the first component and the inner diameter of the second component to permit them to mate at operating temperatures. Tabs and slots are placed on the periphery of the static components to align the static components with the centerline at build temperature.

Systems and methods for inspecting turbine components are disclosed. In one embodiment, an apparatus includes: a base frame adapted to position an inspection device relative a turbine component; and a set of mounts connected to the base frame, the set of mounts adapted to connect the base frame to at least one other point of the turbine component and to pivotally connect the base frame to a pivot point of the turbine component.
摘要:
A method is provided for configuring two thermal processing systems. The method includes providing a first consumable for use in a first thermal processing torch and a second consumable for use in a second thermal processing torch. The first and second consumables have substantially identical physical characteristics. The first and second torches are mounted in a first thermal process system and a second thermal processing system, respectively. The method also includes sensing, by the first thermal processing system, first data stored in a first signal device associated with the first consumable and sensing, by the second thermal processing system, second data stored in a second signal device associated with the second consumable.
摘要:
A level includes a body comprising a first portion having a first reference surface, and a second portion having a second reference surface, the second reference surface being spaced from the first reference surface. The body also includes an intermediate member comprising a wall positioned between the first and second portions, the wall being generally perpendicular to at least one of the reference surfaces. The level also includes an orientation indicator coupled to the intermediate member, the orientation indicator being positioned to indicate an orientation of at least one of the first and the second reference surfaces. The level additionally includes an indicator support configured to support the orientation indicator, and a resilient member positioned between the orientation indicator and the indicator support. A compression the resilient member facilitates a calibration of the orientation indicator, while the indicator support supports the resilient member and engages opposite sides of the wall.
摘要:
A prewinder apparatus attachable to a drive tool to install a helical coil insert includes a body connected to the drive tool. An adapter rotates and is releasably connected to the body at operator selected positions. A prewinder portion displaces in/out of the body. The prewinder portion translates into the body until a fastener engaged with the prewinder portion contacts a stop member defining a predetermined helical coil insert insertion depth. A mandrel axially extends from the prewinder portion when the prewinder portion moves into the body to rotatably insert the helical coil insert. A clutch engages/disengages the mandrel from a drive member. A second clutch or a stall device stalls the drive tool after coil insertion.
