A diffuser tower assembly having a diffuser with a flared end and a fitting with an offset portion and nipple sized for the flared end. The assembly may be configured for providing low coverage purging. Diffuser tower assemblies may be in the form of a kit for retrofitting existing front opening wafer containers. The inlet fitting may include structure that enhances purge characteristics near the base of the porous media diffuser for enhanced sweeping of the floor of the substrate container. Embodiments of the disclosure generate an uneven flow distribution that provides a non-uniform flow distribution at the opening. In an embodiment, where the opening is in a substantially vertical orientation, the non-uniform flow distribution is tailored to deliver a greater flow rate to the bottom half of the opening than to the top of the opening.

Towers for substrate carriers

The deadbolt thumbturn assembly of the present invention includes a thumbturn including a thumbturn extension, which is inserted through a bushing collar and rose bearing, then secured with a retaining ring such that the thumbturn extension is able to rotate within the bushing collar. The threaded bushing collar is then inserted through the aperture of the deadbolt rose and secured with a retaining ring forming a deadbolt thumbturn assembly such that the threaded bushing collar is able to rotate with respect to the deadbolt rose. The thumbturn assembly is then attached to the deadbolt lock by fastening the bushing collar to the threaded boss of the inside housing and inserting the extension of the deadbolt actuator into a receptacle of the thumbturn.

Deadbolt thumbturn assembly

The invention is directed to a device to protect a deadbolt assembly from tampering. A deadbolt assembly comprising a deadbolt reciprocable along a longitudinal axis, and a deadbolt actuating mechanism having an axis transverse to that of the deadbolt, is protected from intrusion and tampering by a pair of protective shells which encircle the actuating mechanism. The shells are generally cylindrical and of like structure and opposite orientation. Each shell comprises a ring and a circumferentially extending protective structure which extends axially toward the ring of the other shell. A preferred protective structure comprises a plurality of projections, including an arcuate tongue. A gap or opening in the protective structure permits actuation and movement of the deadbolt without interference with the shells.
