An exemplary closure assembly includes a rail assembly and a door assembly movably mounted to the rail assembly. The door assembly includes a rotary damper having a pinion, and the rail assembly includes a rack member operable to engage the pinion. As the door moves from first position to a second position, the rack member engages the pinion, thereby causing the pinion to rotate in a first rotational direction. The rotary damper resists rotation of the pinion in the first direction, thereby slowing movement of the door toward the second position. The rotary damper may be a one-way damper that does not resist rotation of the pinion in a second rotational direction such that the rotary damper does not resist movement of the door from the second position toward the first position.

SOFT SELF-CLOSE DOOR DAMPER
20210355731 · 2021-11-18 ·

A door damper assembly that includes a housing, a damper that includes a fixed end and a movable end disposed within the housing, a carriage assembly that is movable within the housing between a closed position and an open position, a claw assembly pivotably attached to the carriage assembly, and a spring positioned to bias the carriage assembly to the closed position. The movable end of the damper is secured to the carriage assembly. The claw assembly is movable with the carriage assembly between the closed position and the open position. The claw assembly is movable relative to the carriage assembly between a non-toggle position and a toggle position. The claw assembly includes a pin receiving space defined therein that defines a claw axis that is generally vertical when the claw is in the non-toggle position and not vertical when the claw assembly is in the toggle position.

Sliding security door with passive deadlock prevention

In a high-security sliding-door apparatus for closing and opening a corridor, the door having (a) a door frame having a track and a bi-directional effector, (b) a carriage having track-engaging rollers, (c) a slide plate slidably secured to the carriage and driven by the effector, and (d) a controller controlling slide-plate movement and enabling the door to be continuously closed but not locked, the improvement comprising centering apparatus for relative positioning of the slide plate and carriage, the centering apparatus including (1) a yoke attached to the slide plate at a yoke pivot and having a yoke cam surface thereabove, (2) a carriage-attached yoke-cam follower, and (3) springs having proximal ends attached to the yoke spaced above the yoke pivot and distal ends each attached to the carriage at points offset from the yoke pivot in opposite lateral directions, centering the door with the slide plate when unlocked.

Method and apparatus for making a composite pipe

A method of making a composite pipe has the steps of (a) providing one or more sources of composite tape, the composite tape being formed of reinforcing fibres embedded in a thermoplastic matrix; (b) helically winding the composite tape(s) around a cylinder under the application of heat to form a pipe comprising fused, concentric layers of adjacently positioned, helically-wound composite tape; (c) scanning a region where edges of wound composite tape are expected to be, to generate scanning information; (d) controlling the gap between further adjacent windings by (1) using the scanning information to determine wound composite tape edge position(s), and (2) using the determined wound composite tape edge position(s) to adjust the winding process during winding; (e) repeating steps (c) and (d). The invention also relates to a corresponding apparatus for making a composite pipe.

Drive unit

A large diameter portion is provided on one side of a closing side drum in an axial direction, a small diameter portion having a diameter gradually decreasing from the large diameter portion to the other side of the closing side drum is provided on the other side of the closing side drum, a partition wall disposed between adjacent small diameter cable grooves in the axial direction of the closing side drum to prevent a closing side cable from slipping out of the small diameter cable grooves is provided in the small diameter portion. Accordingly, the thick partition wall provided in the small diameter portion can reliably prevent the closing side cable from slipping out (derailing) from the small diameter cable grooves even when a winding position of the closing side cable on the closing side drum is changed and transferred from the large diameter portion to the small diameter portion.
