Abstract: A chainsaw chain includes a plurality of drive links, a plurality of cutters, and a plurality of rivets. Each drive link includes a drive link body, a rivet hole extending through the drive link body, and a tang configured to engage a drive element of a chainsaw. Each cutter includes a cutter body having a rivet hole extending therethrough, a cutting tooth coupled to an upper portion of the cutter body, a carbide cutting tip coupled to the cutting tooth, a feed limiter coupled to the upper portion of the cutter body and spaced from the cutting tooth, and a gullet defined between the cutting tooth and the feed limiter. The plurality of rivets is received within corresponding rivet holes of the plurality of drive links and the plurality of cutters, to couple the plurality of drive links and the plurality of cutters together.

Abstract: A chainsaw chain includes a plurality of drive links, a plurality of cutters, and a plurality of rivets. Each drive link includes a drive link body, a pair of rivet holes extending through the drive link body, and a tang extending from the drive link body and configured to engage a drive element of a chainsaw. Each cutter includes a cutter body having a pair of rivet holes extending therethrough, a cutting tooth coupled to an upper portion of the cutter body, a feed limiter, and a gullet. The cutter body defines a longitudinal axis extending through the pair of rivet holes and a vertical axis oriented perpendicular to the longitudinal axis. The cutting tooth is set relative to the vertical axis. The plurality of rivets couples the plurality of drive links and the plurality of cutters together.

Abstract: A refinery system is provided. The refinery system includes a feedstock supply line, a first endothermic chamber that receives feedstock from the feedstock supply and processes the feedstock under elevated heat during a first time period, a second endothermic chamber that receives feedstock from the feedstock supply under elevated heat during a second time period, and a refining processor downstream and in communication with each of the first chamber and the second chamber. A related method is also disclosed.

Abstract: An insulating device for a beverage container including a flexible insulating sleeve for receiving a beverage container therein. A cover is provided for covering the top opening of the insulating device. A strap is provided to cover the bottom of the insulating device whereby the beverage container cannot pass through the insulating device. The cover is provided with two fastening devices whereby the cover may be secured over the beverage container or may be looped around to form a handle for the insulating device. A belt loop is also provided on the insulating device whereby the entire device may be secured to a belt.

Abstract: A stack of edge supported mail pieces delivered batchwise to a feed system requiring a continuous supply includes fingers moving the back of the stack with pressure responsive means in the fingers to discontinue the drive thereof when the pressure reaches a predetermined level.

Abstract: A document transport including an endless belt driven by a pair of logic controlled servo motors which precisely move a document from a feeding station through a scanning station and into a stacking station. As documents are passed through the scanning station, images of the characters thereon are projected by a scanner onto a single columnar retina. The scanner includes a single shaft which is repetitively rotated through a preselected arc by a logic controlled servo motor synchronized with the transport control system. An illumination mirror is mounted on one end of the shaft and an image mirror is mounted on the other so that illumination from a lamp is scanned across the characters to be read while the illuminated images are reflected from the image mirror onto the retina.
