A method of monitoring an additive manufacturing process, in which an object is built in a layer-by-layer manner by directing a laser beam using at least one movable guiding element of a scanner to solidify selected regions of a material bed. The method includes recording position values generated from a transducer measuring positions of the at least one movable guiding element, recording sensor values generated from a sensor for detecting radiation emitted from the material bed and transmitted to the sensor by the movable guiding element of the scanner, and associating each sensor value with a corresponding one of the position values.

An exemplary torque-limiting spindle includes an input member, an output member, a clutch mechanism, and a bias mechanism. The input member extends along a longitudinal axis, is configured for connection with a handle, and includes a first engagement feature. The output member extends along the longitudinal axis, is configured for connection with a rotatable member of a lockset, and includes a second engagement feature. The clutch mechanism includes the first engagement feature and the second engagement feature. The bias mechanism is engaged with the input member and the output member and exerts a biasing force urging the first engagement feature and the second engagement feature into engagement with one another.

An adjustable latch configured to accommodate different backset lengths. The adjustable latch includes inner and outer housings, at least a portion of the inner housing being structured for axial and rotational displacement within the outer housing as an engagement projection of the inner housing is displaced about an adjustment slot of the outer housing. The apparatus may include a bolt assembly having a bolt rod and a latch bar, the bolt rod having projections that are structured to be adjacent to the latch bar when the bolt rod is at a first rotational position and at first or second axial positions. When the bolt rod is at a second rotational position, the axial positions of the bolt rod and the inner housing relative to at least the latch bar and outer housing, respectively, may be adjusted to adjust the backset setting of the latch.

A pull handle may include a chassis, a latch disposed at least partially in the chassis, a thumb turn, and a dogging fastener movably disposed on the thumb turn. The thumb turn may be rotatable between a locking position and an unlocking position, where the thumb turn is coupled to the latch such that when the thumb turn is in the locking position the latch is in an extended position and when the thumb turn is in the unlocking position the latch is in a retracted position. The dogging fastener may be configured to move between a dogging position and an undogging position, where in the dogging position the dogging fastener engages the chassis to inhibit rotation of the thumb turn.

A collinear latching and locking system is disclosed. In embodiments, the system includes a strike with a lock bolt disposed at or defined by an end of the strike. The system further includes a latch pawl configured to surround at least a portion of the strike. The strike and the latch pawl are configured to actuate linearly along the same axis. In this regard, the strike and the latch pawl have a collinear configuration and actuation path. The system further includes a latch cam configured to actuate the latch pawl from a latched position to an unlatched position when the latch cam is turned.

A magnetic latch for fastening a closure member to a support. The magnetic latch comprises a latch bolt assembly comprising: a first elongated housing configured to be mounted with its rear side facing either the closure member or the support; a second housing connected to and positioned underneath the first housing, the second housing being rotatable with respect to the first housing around the vertical direction between a first rotational position in which the latch bolt assembly is operable for a right-handed closure member and a second rotational position in which the latch bolt assembly is operable for a left-handed closure member; and a latch bolt mounted in the second housing. The different rotational positions of the second housing allow using a horizontally moveable latch bolt while retaining a symmetrical placement on the closure system irrespective of the handedness of the closure member.

The present gated barrier includes a two step latch apparatus having a pivoting latch release and a slideable latch puller to operate a latch. The latch apparatus housing is engaged over a junction between first and second frame portions to hide the junction from sight, where one frame portion is arched and the other frame portion is straight. The gated barrier further includes vertical tubular frame members with oblong shaped sections, wall cups with front retaining walls, a warning tag engaged between a gate and a nonparallel end frame portion, and a gate frame with interior vertical frame members in a repeating height pattern supporting an upper arch.
