Abstract: ABSTRACT OF THE DISCLOSURE     A burner for reduced NOx emission and also for the control of the shape of the flame as regards its length and spread, comprises a first combustion zone, which is contained within a cylindrical chamber lined with refractory material.  A burner tube is inserted through an opening in the upstream end of the first combustion zone, the burner including means for providing and burning liquid and gaseous fuel.   A first air plenum is provide upstream of the first combustion zone with means for supplying less-than-stoichiometric combustion air in a tangential swirl-ing manner, prior to entering the first combustion zone.  A second air plenum is provided coaxial with and surrounding the first combustion zone and tertiary air is supplied tangentially to this air plenum so that the tertiary air will flow in a helical swirling motion along the outside of the first combustion chamber,around the downstream end of the combustion chamber and will meet and mix with the hot products of combustion from the first combustion chamber.  Control of the shape of the flame is pro-vided by controlling the relative directions of tangential flow of air in the two plena.

During normal operation the valve element actuated by the diaphragm will co-act with the valve seat of the orifice device to regulate the thruput flow, while engaging a valve stem of the orifice device to hold the same open.  The orifice device has a body through which the valve stem extends.  A helical spring interconnects the body and the valve stem by being separately thread-ed to each component whereby the orifice device is normally biased in a closed position.

The voltage is then converted to a pulse within the timed operational limits of the line voltage for gating the semiconductor, and hence producing a brightness of the lamp between predetermined limits of full dim to full bright.  Preferably, the high frequency voltage carrying the control information arrives superimposed on the line voltage to thereby avoid having to use a separate set of leads to the lamp to provide light level control signalling.

Abstract: ABSTRACT OF THE DISCLOSURE      A pipeline stopper assembly of the expanding sleeve type for use in large diameter pipes having a transverse circular cut-out or opening therethrough.  The pipeline stopper assembly cooperates with a stopper fitting secured to the pipeline so that when the assembly is inserted into the transverse opening in the pipeline and is properly oriented with the space between the split sleeve facing in the proper direction, it is incapable of being rotated within the opening.  The torque encountered in the expanding of the sleeve by the actuating means is transferred directly from the operating nut members to the sleeve without being transferred through the toggle arms.  Stop means are provided which limit movement of the operating nut members toward each other and, thus, positively limit the amount of expansion of the sleeve and the pivotal movement of the arms to an angle no greater than 90° to the longitudinal axis of the stopper assembly. By providing stop means coacting directly with the nut members, no unnecessary loads are transferred to the toggle arms or their pivots and this coupled with the elimination of torque from the toggle arms enables the arms and their pivots to be made of a lighter and cheaper material.
