A device operable, by a user standing above the grade of a pipe, to install a hoisting strap around the pipe. A device body carries wheels and has an opening structured for installation onto the pipe at a mid-span location. The opening is reversably enlarged during installation of the device to permit entrance of the pipe into partially encircled engagement by the body. Typically, three or more wheels are biased by the body into rolling engagement on the pipe at the installed position. Once installed, the device captures an end of the hoisting strap, and carries the strap end under the pipe as the device is rotated about the pipe centerline. The strap end can then be removed from the device to sling the pipe in a conventional lifting arrangement. The device can be removed from the pipe by pulling the device to again expand the opening.

A solid mast raiser system is disclosed herein. The solid mast raiser system may include a slot configured to house a mast. Further, the slot may be further configured to be inserted in to a predrilled bore in the ground. Further, a length of the slot may be matched to a depth of the predrilled bore in the ground. Further, the solid mast raiser system may include a stanchion configured to be attached to the slot. Further, the stanchion may be concentrically aligned with the slot. Further, the stanchion may rest upon a cable. Further, the solid mast raiser system may include a launcher coupled to the stanchion through a cable. Further, the launcher may be configured to raise and retract the stanchion. Further, the launcher may be configured to be affixed to the ground. Further, the launcher may comprise a first hole concentrically aligned with the slot.

Disclosed is a method for unpacking a component 16 manufactured by means of a generative manufacturing process, from a particulate material fill 18. In the method, an auxiliary frame 20 having a vertical circumferential wall structure 22, open downward, is arranged above a vertical circumferential wall structure 12 of a construction box 10. In addition, a construction platform 14 of the construction box 10 is displaced upward, so that the particulate material fill 18 containing the component 16 is transferred from the construction box 10 to the auxiliary frame 20. In addition, the auxiliary frame 20 with the particulate material fill 18 containing the component, and the construction box 10 are moved away from each other, and the component 16 is unpacked from the particulate material fill 18 at least in part and is removed from the auxiliary frame 20.

Disclosed is an extractor for an airplane galley storage container. The extractor may include a rigid frame with a grip on a first end portion connected to an extractor arm on an opposite, second end portion of the rigid frame. When the grip is pulled, the extractor arm moves correspondingly proximally from its position on the opposite end of the rigid frame. When the grip is released, at least one constant force spring, stored in a spring housing on or near a distal end of a rigid frame of the extractor, biases the extractor arm and grip distally to a rest position.

In a lifting and transporting device for lifting a load (13) and for transporting the same transversely to the lifting direction (8), for use in the production of a screwed flange connection (35), in order to bring a tensioning tool (13) into a tensioning position in which it is in engagement with a screw bolt connection (18) to be pretensioned, or into a transport position in which it is out of engagement with a screw bolt connection and can be transported to the next screw bolt connection, wherein the flange (36a, 36b) extends horizontally, comprising a frame (2) for picking up and for lifting a load (13), a holding device (3) for holding the load, wherein the holding device is movable relative to the frame in the lifting direction (8), and comprising a hoisting device (4) for lifting and lowering the holding device (3) with the load (13) attached thereto, wherein the frame (2) is mounted on a first and a second support bearing (5, 6) and the first support bearing (5) is designed for abutment against the flange upper side (14), the frame (2) is designed to extend from the flange upper side (14) along the flange face (15) to below the flange underside (16), the second support bearing (6) is designed for abutment against the flange upper side (14) or against the flange face (15), the holding device (3) is equipped to hold the tensioning tool (13) below the flange underside (16) with the engaging means directed upwards, and the hoisting device (4) is equipped to lift the holding device (3) with the tensioning tool (13) attached thereto from a lowered transport position into a tensioning position.

A system for controlling a tension of a tether between an object and a load tethered to the object comprises magnetorheological (MR) fluid actuator unit(s) including at least one torque source and at least one MR fluid clutch apparatus coupled to the at least one torque source to receive torque from the at least one torque source, the MR fluid clutch apparatus controllable to transmit a variable amount of torque via an output of the MR fluid actuator unit. A tensioning member is connected to the output so as to be pulled by the output member upon actuation of the magnetorheological fluid clutch apparatus, a free end of the tensioning member adapted to exert a pulling action when being pulled by the output member. Sensor(s) provide information indicative of a relation between the object and the load tethered to the object. A controller controls the at least one MR fluid clutch apparatus in exerting the pulling action based on said information.

A device for removing polycrystalline silicon rod pairs from a Siemens reactor has a body dimensioned to fit over a single rod pair. Once the rod pair is within the body, the body and enclosed rod pair is removed.
