A steam sterilizer having a door movable relative to an opening between a first open position and a second closed position. A plurality of spaced-apart roller assemblies are aligned along edges of the door to align the door relative to the opening as the door moves between the open and closed position. Each of the roller assemblies are comprised of a cylindrical roller having an outer annual recess extending along the periphery thereof. The recess is dimensioned to receive a lateral edge of the door. The roller is mounted on a shaft and is movable against a biasing force axially along the axis of the shaft.

Described herein are systems, methods, devices, and other techniques for implementing smart windows, smart home systems that include smart windows, and user devices and applications for control thereof. A smart window, or photovoltaic window, may include a photovoltaic configured to generate electrical power from incident light onto the photovoltaic window, store the electrical power, and send the electrical power to an electronics package or various electrical loads including a wireless communication system, sensors, or window functions. The photovoltaic window may communicate with various smart home system devices such as hub devices and user devices, which may include the reception of control data at the photovoltaic window and the transmission of sensor data captured by the window sensors.

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.

A dock door assembly and a dock door assembly kit are provided for use in a dock door opening for installation in a warehouse. The dock door assembly comprises a pair of vertical tracks, with each vertical track configured to be attached to a wall along opposing lateral sides of the dock door opening. The dock door assembly also comprises a multiple, horizontal section door characterized by a vertical height when closed and mounted on the pair of vertical tracks. The dock door assembly further comprises a spring shaft assembly and a pair of headplates with each headplate having a U-shaped opening to receive each end of a torsion shaft. Further, the dock door assembly may comprise a pair of door cables and a pair of corner cable attachments connecting each door cable to the spring shaft assembly.

A latch assembly for a fenestration assembly includes a keeper ridge configured for coupling with a fenestration frame. An assembly housing is configured for coupling with a rail of a sash, including upper or lower rails opposed to a check rail of the sash. A latch mechanism is movably coupled with the assembly housing. The latch mechanism is at least partially concealed with the rail. The latch mechanism includes a handle pivotally coupled with the assembly housing and a latch arm pivotally coupled with the assembly housing and operatively coupled with the handle. The latch arm includes a locking face configured for alignment with the keeper ridge.
