Abstract
Abstract A storage bin activator device that directs a precise pattern of multiple instantaneous energy bursts of impact, aeration and sonic stimulation directly into bulk material within the storage bin to free same for discharge. Also disclosed is a method for restoring free flow or removing disruptive material in a storage or other containment vessel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
178 words
A material activator device to initiate the free flow of material or remove disruptive materials from a containment vessel, comprising at least one injector means for introducing sequential energy bursts of compressed gas into the containment vessel, programmer means for regulating the length of the energy bursts, the intervals between the energy bursts and the number of the energy bursts in each sequential burst pattern, each said length of the energy bursts and the intervals between the energy bursts being in an adjustable programmer signal range of 20 to 100 milliseconds establishing said sequential burst pattern of multiple linked sequential energy bursts which act on moving particles of material before the moving particles come to rest, said programmer means also establishing different intervals than the intervals between the energy bursts so as to create separated sequential burst patterns, whereby the sequential energy bursts of compressed gas in each sequential burst pattern provide multiple linked impact, aeration and vibration forces at or near sonic frequency to induce free flow of material or dislodge disruptive materials in the containment vessel.
Claim 2
Dependent Claim
178 words
A material activator device to initiate the free flow of material or remove disruptive materials from a containment vessel, comprising at least one injector means for introducing sequential energy bursts of compressed gas into the containment vessel, programmer means for regulating the length of the energy bursts, the intervals between the energy bursts and the number of the energy bursts in each sequential burst pattern, each said length of the energy bursts and the intervals between the energy bursts being in an adjustable programmer signal range of 20 to 100 milliseconds establishing said sequential burst pattern of multiple linked sequential energy bursts which act on moving particles of material before the moving particles come to rest, said programmer means also establishing different intervals than the intervals between the energy bursts so as to create separated sequential burst patterns, whereby the sequential energy bursts of compressed gas in each sequential burst pattern provide multiple linked impact, aeration and vibration forces at or near sonic frequency to induce free flow of material or dislodge disruptive materials in the containment vessel.
Claim 3
Dependent Claim
35 words
The material activator device as defined in claim 1 wherein the injector means comprises an electrically operated valve means controlled by said programmer means, and compressed gas storage means controlled by said electrically operated valve.
Claim 4
Dependent Claim
43 words
The material activator device as defined in claim 2 wherein both said electrically operated valve means and compressed gas storage means are mounted immediately adjacent to one another and to said containment vessel in order to maximize response time with minimum system losses.
Claim 5
Dependent Claim
53 words
The material activator device as defined in claim 1 wherein the programmer means has multiple channels of electrical signal output and timer means, and said programmer means controls the number of electrical signal pulses per channel, the total on and off time of the signal pulses, and the time between initiating complete programs.
Claim 6
Dependent Claim
42 words
The material activator device as defined in claim 1 wherein the programmer means has multiple channels of output, and the sequential burst pattern from at least one channel of output is different from the sequential burst pattern of another channel of output.
Claim 7
Dependent Claim
35 words
The material activator device as defined in claim 5 wherein the sequential burst pattern from at least one channel of output operates during the separated intervals between sequential burst patterns of another channel of output.
Claim 8
Dependent Claim
23 words
The material activator device as defined in claim 1 wherein the different intervals between separated sequential burst patterns are of the same duration.
Claim 9
Dependent Claim
28 words
The material activator device as defined in claim 1 wherein there are a plurality of injector means, each of which are operated and controlled by said programmer means.
Claim 10
Independent Claim
165 words
A method for initiating free flow or removing disruptive materials from a containment vessel, comprising the steps of introducing sequential energy bursts of compressed gas into the containment vessel, regulating the length of the energy bursts, the intervals between the energy bursts and the number of energy bursts in each sequential burst pattern, each said length of energy bursts and the intervals between the energy bursts operable in an adjustable programmer signal range of 20 to 100 milliseconds establishing said sequential burst pattern of linked sequential energy bursts which act on moving particles of material before the moving particles come to rest, each said sequential energy burst pattern also being separated from one another by a different interval than the interval between the energy bursts, whereby the sequential energy bursts of compressed gas in each sequential burst pattern provide multiple linked impact, aeration and vibration forces at or near sonic frequency to induce free flow of material or dislodge disruptive materials in the containment vessel.
