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.

The invention is directed at a method of positioning a carrier on a flat surface using an positioning member, wherein the carrier comprises an upper part and a base which are connected to each other such as to be arranged remote from each other, wherein the positioning member is arranged between the base and the upper part such that the base is located at an opposite side of the positioning member with respect to the upper part of the carrier, the upper part resting on the positioning member prior to placing of the carrier onto the flat surface, wherein the upper part comprises three engagement elements, and wherein the positioning member comprises a support surface for receiving the three engagement elements of the upper part, said support surface including a plurality of sockets forming a kinematic mount for said three engagement elements, wherein the base comprises three landing elements, each landing element being associated with a respective one of the three engagement elements, and the method comprising the steps of: operating the positioning member for moving the carrier relative to the flat surface in a direction parallel thereto such as to position the carrier above a landing position; performing an action of placing the carrier on the flat surface at the landing position, said action of placing comprising: moving the base towards the flat surface until at least one of said landing elements is in contact with the flat surface and an associated engagement element of said engagement elements is released from the kinematic mount; continue said moving of the base relative to the flat surface until all landing elements are in contact with the flat surface; and continue said action of placing the carrier until all engagement elements are released from the kinematic mount.

One embodiment provides a drive system that includes a drive device with at least one drum for spooling at least one wire rope. A mounting device is connected to the drive device and a single-axis tracker. At least one partial pulley is connected to a torque tube. The at least one partial pulley is configured to accept the at least one wire rope and to transfer leveraged drive forces to the torque tube.

A bracket for supporting an object, the bracket including a base; a pair of holding plates pivotably mounted to the base with a pivot; a pair of apertures, each aperture disposed on each holding plate; and a shaft including a first end, a second end and a spherical member disposed on the first end of the shaft, the spherical member is configured to be rotatably coupled to the pair of apertures of the pair of holding plates, wherein the object is configured to be supported on the second end of the shaft.

A foldable container includes a foldable supporting frame, at least one operation switch arranged on the foldable supporting frame, and a container body supported on the foldable supporting frame. The operation switch is actuated through a pulling operation to move the foldable supporting frame between an unfolded mode and a folded mode. The container has an edge and an opening formed within the edge. At the unfolded mode, the opening is opened. At the folded mode, the opening is closed. The container body is automatically folded as the foldable supporting frame is moved from the unfolded mode to the folded mode. Via a folding method, the foldable supporting frame is folded to reduce an overall size for occupying less storage space when it is not in use.

A plate provides clearance between a camera and a quick-release receiver securing the camera to a support.

A motor including a rotor, a first arm, a mount, a stator, a first bearing, and a second bearing. The motor is configured to rotate the rotor. The mount connected to the first arm. The stator coupled to the mount. The first bearing located between and connecting the rotor to the stator. The second bearing located between and connecting the rotor to the mount. The first arm prevents movement of the stator and the mount.

The disclosure relates to an accessory support device, comprising a support structure that defines a flat base plane. And comprising an inclined portion that is supported on the support structure that extends in an inclined plane upward relative to the base plane from a front of the accessory support device to a rear of the accessory support device. The accessory support device further comprises an upright portion that is supported on the support structure or on the inclined portion that extends in a mainly upright plane relative to the base plane from the rear of the accessory support device, so as to form a privacy panel that shields the user from being seen from the rear of the accessory support device. The upright portion and the inclined portion are angularly adjustably connected via an angle compensation device to compensate the upright portion for angular adjustment of the inclined portion.

A quick release assembly and gimbal system are disclosed. The gimbal system includes a handheld gimbal and an apparatus for mounting an electronic structure on the handheld gimbal. The handheld gimbal includes a handheld structure, a gimbal body operably coupled with the handheld structure, and a connector assembly operably coupled with the gimbal body. The connector assembly includes a first set of attraction structures. The apparatus includes a mounting structure attachable to the electronic structure. The mounting structure includes a second set attraction structures. The first set of attraction structures are configured to attach to the second set of magnets, the first set of attraction structures and the second set of attraction structures configured to cause at least one of the connector assembly or the mounting structure to rotate in a direction such that the mounting structure is coupled to the connector assembly.
