A method and apparatus for marking positions for installing door lock elements of a door, the door attached to a frame having a header including comprising the steps of providing a positioning member, at least partially opening the door; attaching the positioning member to the door, while the door is closed causing the positioning member to attach to the door frame; and opening the door and removing the positioning member from the door; and using the at least one mark to install a strike plate, deadbolt receiving plate, and/or electric strike.

Some examples of the present disclosure relate to welding systems that provide cooling gas flow to contact tips. The contact tip may be retained within a neck and nozzle assembly of a welding torch that receives gas, such as shielding gas, for example, from the welding system. A tip retention-device and gas diffuser may cooperate to retain the contact tip within the neck and nozzle assembly. The gas diffuser may have axial gas channels configured to direct the shielding gas over and/or across a rear portion of the contact tip seated within the gas diffuser. The tip retention device may have gas channels configured to guide gas flow from the gas diffuser over and/or across a forward portion of the contact tip. The gas flow may help to cool the contact tip before, during, and/or after welding, which may extend the life of the contact tip.

A process for installing a section of packing in a casing by means of a device to assist installation of a section of packing, the casing comprising at least one tubular wall extending in a longitudinal direction (L) between two longitudinal ends, and an inner face of which participates in delimiting a receptacle for the section of packing, the casing being positioned horizontally during the process for installing the section of packing, the process comprising a step of fitting of the device to assist installation on the casing, during which the device to assist installation is secured in the vicinity of the input opening of the casing, a step of positioning of the section of packing relative to the device to assist installation and to the input opening, and at least one step of pushing during which the section of packing is pushed into the receptacle of the casing.

A spindle repair kit including a pair of alignment mandrels positionable in a respective spindle bore of a steering spindle. An alignment rod is operative to retain the mandrels in their respective spindle bores. The kit can also include a first clamp member and a second clamp member, each being positionable between the spindle bores. The kit includes a drill fixture including a drill mounting surface and a bearing fixture including a bearing aperture sized to receive the alignment rod. Fasteners clamp the drill fixture and first clamp member to the first spindle bore and clamp the bearing holder and second clamp member to the second spindle bore. The kit includes an arbor connectable to a drill and a reamer, wherein the arbor is sized to position the reamer in the first spindle bore.

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.

When plate-shaped components are inserted in the correct order and orientation into component insertion grooves of a component assembly jig, the component insertion grooves are blocked by the plate-shaped components, and the blowing of compressed air is stopped. When the blowing of compressed air from the component insertion grooves is stopped, the pressure in a compressed-air path increases, and an alignment-complete lamp is illuminated. Using the component assembly jig enables an assembly operation for overlapping the plurality of plate-shaped components in the correct order and orientation, without excess or deficiency, to be efficiently performed without error.
