Definitions

• n conveying materials, as for instance a liquid, through pipes, and especially those having a comparatively smooth interior
• the resistance ofthe pipe in- Aterior is not sufficient tomix the liquid and that the peripheral flow will give up, or receive, heat while the center flow will, .except to a slight extent, be little affected.
• the objects of our invention are therefore, to provide a device which may be readily inserted in a pipe, that will deflect the center and peripheral flow of the material therein, to accomplish this deflection with ⁇ the least possible resistance to the iow, and without materially reducing the capacity of the pipe line.
• Figure 1 is a central longitudinalsection throu h a pipe and current diusingdevice emb ying my invention.
• Fig. 2 is a transverse section through a pipe, the current diffusing device being shown in elevation.
• Fig.v 3 is a cenral longitudinal section through a pipe showing a modification of my invention.
• Fig. 4 is a transverse section through a pipe showing this modification in elevation.
• Figs 5 and 6 are central longitudinal sections of pipes showing further modifications of my invention.
• reference character l designates a pipe for conveying liquids or gases and contains therein a current difusin device comprising 'an annularring 2 having an external dia-meter substantially that of the internaldiameter of the pipe, and a diametrically disposed web 4 having deecting faces diverging in the direction of the current flow.
• the arrows indicate the effect of the diHusing device upon the central and peripheral flow of the liquid or gas from which it will be seen that the currents are thoroughly mixed giving out or taking in properties lof a uniform degree of temperature.
• a pipe l is here shown ring 2 and-dianietrical web 4, the latter being provided with a ⁇ conical member 5 disposed concentrically 'with its axis coinciding with the axis of the ⁇ pipe and its apex foremost in the direction of the flow of liquid,
• 4ring2 is provided with a plurality of-webs converging at a point 7 foremost in the direction lof flow of the liquid, and as shown in Fig. 6 the webs may diverge from a conical member 8 vsecuring the latter to the ring 2, the conical member 8 being arranged concentrically with respect to the pipe 1 and with its apex foremost in the direction of liquid flow.
• diffusing means including a transversely disposed annular wall disposed with its periphery in engagement with the interior of the wall of said conveying pipe,
