A miter saw assembly includes a base and a turntable rotatable in relation to the base. The miter saw further includes a cutting assembly having a saw blade configured to cut a work piece positioned on the turntable. In addition, the miter saw includes a dust conduit positioned to receive saw dust generated by a cutting operation of the cutting assembly on the work piece. The miter saw also includes a support assembly coupled to the turntable and configured to support the cutting assembly, the support assembly including (i) a carriage mechanism configured to enable linear movement of the cutting assembly in relation to the turntable, and (ii) a pivot mechanism configured to enable pivotal movement of the cutting assembly in relation to the turntable. The saw blade possesses (i) a first lateral face that defines a first plane, and (ii) a second lateral face that defines a second plane. A zone is defined between the first plane and the second plane. At least a portion of the dust conduit is positioned in the zone. All of the pivot mechanism is spaced apart from the zone.

Discloses a system for the analysis and measurement of selected gases such as combustible gases contained in a gaseous sample to be analysed including a mixing manifold arrangement to mix the sample gas with a diluting gas to provide a constant gas output flow rate to a detector system. The mixing manifold arrangement automatically reconfigures itself to provide an optimal concentration ratio of sample and diluting mixed gas to the detector system. A constant sample gas input rate is preferred. Excess sample gas not required to maintain a constant mixed sample output rate is discharged.

A novel load cell for use in novel wheel load scales and novel weigh-in-motion scales is provided herein. The load cell comprises a metal rod or bar, with a strain transducer secured to a flattened portion of each of the upper and lower faces of the metal bar. A signal wire has its terminal secured to an end face of each of such strain transducer, and a strain relief means is interposed between each such signal wire terminal and its associated strain transducer. When mounted within a closed bore which is parallel to the upper surface of a flat plate of elastic material, e.g., sheet metal, in a particularly-recited manner, an improved wheel load scale or weigh-in-motion scale is provided. This provides a light weight, low profile, scale which is isolated from external interference, which improves the accuracy of the scale.
