A retention knob tool. A tubular body is held in a tubular sleeve, and symmetrically formed around an axis. The tubular body also has an internal bore. Four locking ball retainer sockets are formed in the tubular body. A retention knob aperture is recessed within a top plate. Four balls are movably held in the ball retainer sockets. A tubular end stop is affixed to the tubular body rearward end. A drive tool cavity is recessed within the tubular body rearward end. The sleeve forward end includes a recessed circumferential portion bounded by a first thicker portion of the inside wall, where the first thicker portion bears against the balls when the tubular body is translated rearwardly not an inward lock position and the inward force is removed from the plurality of balls when the tubular body is extended forwardly into a released position.

A cable retention and release mechanism includes a cable gripping device including a cable passage. A cable extends through the cable passage. A cable gripping device collar is movably coupled around the cable gripping device. An outer cable gripping device surface is seated against a cable gripping device receiving inner surface preventing movement of the cable gripping device relative to the cable gripping device collar. The cable gripping device receiving inner surface clamps the cable gripping device on the cable and prevents sliding movement of the cable. A jack is movably coupled with the cable gripping device collar. In a first engaged position the jack is engaged against the cable gripping device proximal end. In a second engaged position the jack unseats the outer cable gripping device surface from the cable gripping device receiving inner surface and releases the clamping of the cable.

Floor panels are shown, which are provided with a mechanical locking system comprising tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.

This application relates to a method for disassembling a portable electronic device. The method can include generating data associated with disassembling the portable electronic device based on measurements of a housing of the portable electronic device, removing a display assembly from the housing using a first module of a modular system based on the measurements of the housing, and removing an energy storage component from the housing using a second module of the modular system based on the measurements of the housing.

According to some embodiments, a method operable by an electronic component recovery system for detaching an electronic component adhesively bonded to a housing by way of an adhesive bond, is described. The electronic component is carried within a cavity defined by the housing of a portable electronic device. The method can include while the housing having the electronic component attached thereto is located at an electronic component detaching module, where the electronic component detaching module includes a movable arm capable of rotating about a hinge: cooling the housing and the electronic component attached thereto to a temperature that is low enough to weaken the adhesive bond, and causing the movable arm to rotate about the hinge such that a portion of the housing strikes a detachment element with sufficient force to separate the electronic component from the housing.

A bolt installation and removal (BIR) system is used for assembling and disassembling a nuclear vessel. The BIR system includes a platform with a stand for supporting the nuclear vessel. A track extends around an outside perimeter of the platform and multiple tool carts include wheels that roll on the track. Tool towers are located on the carts and include tool assemblies configured to install and remove bolts on the nuclear reactor vessel. Magazine towers also extend up from the tool carts next to the tool towers and include magazines that hold bolts for exchanging with the tool assemblies. Drive mechanisms move tool heads in the tool assemblies around a first vertical axis, vertically up and down, and laterally to more simply and reliably install and remove the bolts in a radioactive underwater environment.

A cable retention and release mechanism includes a cable gripping device including a cable passage. A cable extends through the cable passage. A cable gripping device collar is movably coupled around the cable gripping device. An outer cable gripping device surface is seated against a cable gripping device receiving inner surface preventing movement of the cable gripping device relative to the cable gripping device collar. The cable gripping device receiving inner surface clamps the cable gripping device on the cable and prevents sliding movement of the cable. A jack is movably coupled with the cable gripping device collar. In a first engaged position the jack is engaged against the cable gripping device proximal end. In a second engaged position the jack unseats the outer cable gripping device surface from the cable gripping device receiving inner surface and releases the clamping of the cable.

A spike puller for pulling a railroad spike of a track includes a housing, a linear displacement unit mounted at the housing, and a claw unit for gripping the railroad spike. The claw unit is displaceable in a linear manner relative to the housing in a displacement direction by using the linear displacement unit. The linear displacement unit includes a hollow tube which is guided in the housing. A method for pulling a railroad spike of a track is also provided.

A retention knob tool. A tubular body, is held in the tubular sleeve, and symmetrically formed around an axis. The tubular body also has an internal bore. Four locking ball retainer sockets are formed in the tubular body. A retention knob aperture is recessed within a top plate. Four balls are movably held in the ball retainer sockets. A tubular end stop is affixed to the tubular body rearward end. A drive tool cavity is recessed within the tubular body rearward end. The sleeve forward end includes a recessed circumferential portion bounded by a first thicker portion of the inside wall, where the first thicker portion bears against the balls when the tubular body is translated rearwardly into an inward lock position and the inward force is removed from the plurality of balls when the tubular body is extended forwardly into a release position.

A removal device (121, 221) for removing and disposing of a pen needle (113, 213) connectable to a drug delivery device (111, 211) includes a body (123, 223) having a cavity (141, 241) for receiving the pen needle of the drug delivery device such that a patient end (116, 216) of a needle (115, 215) of the pen needle is covered by the body. An ejector (151, 251) is movably connected to the body (123, 223) for engaging the received pen needle (113, 213) and selectively ejecting the engaged pen needle from the body. The pen needle (113, 213) is securely retained within the removal device (121, 221) without exposing the needle (115, 215) of the pen needle until the pen needle (113, 213) can be properly disposed of, such as in a sharps container, thereby substantially preventing an accidental needle stick.
