 PRINCIPLE OF OPERATION
The frequency of air bursts can be programmed in the sub-sonic to low sonic range to direct multiple air bursts at whatever pattern most effectively restores material flow. The use of multiple injectors can overlap, space or parallel the pattern. The air burst pattern and number of injectors depends on bin size, shape and flow characteristics of the material being transported. In the short instant (20 to 100 milliseconds) of the compressed air burst, each burst or injection of compressed air acts directly on the particles it contacts and causes motion in line with the movement and expansion of air. Simultaneously, with the initial movement of the materials, there is aeration of the materials from the expansion of the compressed air. The programmer is set so that before the moving particles from the initial burst come to rest, a second energy release of compressed air is injected into the bulk material. Since the moving particles from the initial burst are still moving, and the activated area is at an elevated pressure, the second burst imparts a greater movement, disruption or aeration force because it is acting on or amplifying the initially moved particles. Each subsequent energy release is programmed to act on materials that are not at rest, but rather have kinetic energy in their movement such that the subsequent energy releases, even though of lesser energy levels than previous bursts, are more effective than the previous bursts due to the amplification effect. The energy level of the particles in motion increases with each burst or pulse to a higher level, and this higher motion is transmitted to more and more particles with impact and aeration stimulation extended into the entire vessel. The energy bursts or pulses are released at a field adjustable rate or frequency that is most responsive to the bulk material in order to achieve sonic stimulation as well. The multiple instantaneous energy releases of impact, aeration and sonic stimulation, act in concert with one another directly on the material to immediately induce free flow. An entire storage vessel can be totally activated to induce free flow in from less than one second to a few seconds. Disruptive materials in pipes, recessed channels, seat areas and other areas are also similarly removed within this time frame. A typical air burst pattern could be programmed to inject five air bursts simultaneously from each of two injectors at a frequency of 20 per second. The injectors could be connected to fire alternately which would double the "-¬frequency. It may be that three bursts per ` injector would establish free flow or it may require nine. Whatever the system requires is simply set into the programmer. The established program is automatically repeated at the time interval selected. FIELD ADJUSTMENTS Field adjustment of the Pulsonic System is accomplished by simply setting dials on the programmer. These dials control: A. Time between programs (.1 to 99.9 minutes) MOUNTING LOCATION We will be pleased to recommend mounting locations of injectors based on your sketch or drawing of your specific material flow problem. On new instal¬ations, recommendations will be made based on experiences in similar structures. For prevention of material retention in recesses, ducts or channels sketches or drawings of problem areas are necessary. INSTALLATION

The Pulsonic Bin Activator system injects pre-programmed multiple sonic air blasts directly into the compacted material, restoring free flow in less than 1 to a few seconds. Frees even the most difficult to move materials by breaking up the compaction, aerating it, thus restoring free flow.
The field adjustable air burst pattern allows the operator to select a pattern of air bursts that is most effective for his application resulting in minimum energy consumption. This is done by simply setting the dials on the programmer. The dials control the frequency, duration and cycle of the air burst patterns.
