Abstract: A vibration isolating mounting clip which is used to mount a furring channel to a mounting surface, which is then further loaded with a finishing substrate via the furring channel consists of a resilient bent metal strip. The resilient bent metal strip has a first end and an opposing second end, and a transition portion shaped to fit the furring channel. Through different aspects of the invention either the first end, or the first and second end is mounted to the mounting surface. The resilient bent metal strip has a stiffness and shape such that when the furring channel is positioned in the resilient bent metal strip, and the resilient bent metal strip is mounted to the mounting surface, and a finishing substrate is loaded on the furring channel, the furring channel does not contact the mounting surface. Between the ends of the resilient bent metal strip, and the furring channel, are one to several bends, towards and away from the mounting surface to achieve the desired resiliency.

Abstract: A seismically restrained vibration isolating mounting device seismically restrains and vibrationally isolates equipment which is supported by an equipment support means, from the equipment mounting surface. This seismically restrained vibration isolating mounting device is comprised of a three-axis snubber mounted to the equipment mounting surface and which restrains the equipment support means; and a vibration isolator, wherein the equipment support means is supported by the vibration isolator and wherein the vibration isolator is supported by the equipment mounting surface, wherein the vibration isolator acts in the direction of gravity, and wherein the three axis-snubber is closer to the equipment supporting surface than the vibration isolator, and the vibration isolator is external to the three-axis snubber.

Abstract: An endless chain for carrying cutting elements for a mining machine comprises a plurality of pivotally interconnected link elements, some of which are constructed to mount outwardly projecting cutting tools. The link elements are pivotally interconnected so as to provide sprocket openings along the two outer edges of the cutting chain. A pair of axially spaced sprockets secured to a driving drum engage the sprocket openings provided along the two longitudinal edges of the cutting chain. The sprocket teeth are dimensioned to be of less peripheral width than the sprocket openings and the pitch of the sprocket openings slightly exceeds the pitch of the sprocket teeth, thus insuring that the driving force imparted to the cutting chain by the sprockets is imparted only by the two leading sprocket teeth as they approach their point of exit from the chain openings.
