Abstract: A centerless turning lathe refinishes multiple laser printer rollers, mags and PCRs simultaneously. The apparatus includes a housing having two members connected by multiple rods. Multiple spindles extend inward from the members. Each spindle has recesses for carrying an O-ring. The O-ring is easily moved from recess to recess along the spindles to accommodate any length of roller. Adapters may be placed over the ends of the spindles for securing and rotating shorter rollers, mags and PCRs. The spindles extending from the members are power-driven by a speed controlled motor. Finely adjustable T-shaped fences extend through holes in the members above the spindles and hold the rollers longitudinally. An applicator assembly for applying chemicals to the rollers includes a guide positioned on and extending between the members of the housing, a movable carriage that travels along the guide, and a multiple treatments foam applicators extending from the carriage.

Abstract: A light source projects a light beam through an insulating multiple glass sheet insulating unit. The size of the beam spot on a target indicates unit thickness.

Abstract: Cantilever attachment method and apparatus are described. A resilient portion of a cantilever assembly holds a first part of an attachment device. The second part of the attachment device is positioned on a side of a post opposite the cantilever assembly. The attachment to the resilient means is positioned opposite an intermediate portion of a base on the cantilever assembly. The base lies against the post when assembled. The cantilever assembly is first tipped upward and the attachment is joined to the resilient portion. Tipping the cantilever assembly downward compresses the resilient portion. Continued rotation of the cantilever assembly downward slightly raises the cantilever assembly along the post and slightly relaxes the compression of the resilient portion, thereby creating an over-the-center clamp.
