A transportable valve rack for securing a plurality of pressure safety or pressure relief valves in an upright position. The valves of the type having a bolted flange-type connection and the rack comprises a base assembly and a top plate mounted on the base assembly. The top plate includes a plurality of areas, with each area comprising a plurality of holes arranged on a circumference of two or more concentric circles. The plurality of holes extends through the top plate and at least four holes are on the circumference of each concentric circle. The holes are sized and arranged to align with bolt holes of pre-selected flanges of particular size and pressure rating. Nuts and bolts extended through aligned holes secure the valve to the valve rack.

A frame lifting mechanism includes a base, a motor, a lead screw, a sliding member, a lifting member and a supporting shaft. The motor is connected to the lead screw, and the lead screw is fastened onto a transmission tube, allowing the transmission tube to move forward and backward while being driven by the lead screw. The sliding member is installed on a sliding track arranged on the base and connected to the transmission tube, allowing the sliding base to actuate with the transmission tube synchronously. A rear end of the lifting base is pivotally attached onto the base for support, and the supporting member uses its two top and bottom ends to be pivotally attached onto the lifting member and the sliding member respectively, allowing the supporting shaft to utilize the movement of the sliding member to drive the lifting member to move upward and downward.

A mount for supportably engaging an article. The mount includes a bulbous member that may include a convexly shaped surface area. The convexly shaped surface area may be supportively contactable with a first interconnect portion of a carrier member. An attachment member that is operatively associable with a device may be removably engageable with a second interconnect portion of the carrier member. The carrier member may be moved throughout a continuum of positions defined by the convexly curved surface area of the bulbous member. Additionally, the bulbous member may be supportably engaged by a variety of embodiments of support structures for supporting or mounting the mount.

A lightweight, portable and configurable system for image acquisition for photogrammetry purposes includes a portable rig having at least two cameras supported thereon in spaced relation to one another. The cameras are angled towards one another and actuated in an automated fashion so as to capture images of an object at a minimum rate over time. At least a plurality of the captured images are used to digitally reconstruct three-dimensional geometry of the object.

A wire pressing and holding device is removably mounted on a first extension arm of an extension arm support mechanism to cover a channel thereof, and includes a cover plate, an engaging protrusion projecting from a first end of the cover plate to be inserted into an engaging recess of the arm to serve as a fulcrum such that a second end of the cover plate is turnable relative to the arm, and a releasably retaining member connected to the second end and configured to be displaceable relative to the second end between a retaining position to retainingly abut against the arm for pressing and holding a wire assembly in the channel, and a releasing position to be disengaged from the arm.
