Abstract
Abstract A grain storage bin having a content stirring machine therein, has a temperature sensor adjacent the stirring tool. The sensor is translated through the material in the bin by the stirring machine. A readout device outside the bin is coupled to the sensor wirelessly, or through slip ring contactors, there being appropriate circuitry associated with the sensor and readout device for the necessary information handling and processing. Possibilities for temperature and humidity determinations in the environment as well as in bin contents, and drier control, as needed, are disclosed.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
104 words
A method of monitoring condition of stored contents of a storage vessel comprising the steps of: locating a contents condition sensor in said stored contents; power driving and thereby transferring said sensor primarily horizontally through said contents and at a substantially uniform depth below the surface of said contents; using the surface of the contents for at least partially supporting the sensor so that the sensor elevation is coordinated with the content surface elevation to follow surface contour and maintain said depth as said sensor is driven; and producing a signal in response to change of condition of said contents sensed by said sensor.
Claim 2
Independent Claim
104 words
A method of monitoring condition of stored contents of a storage vessel comprising the steps of: locating a contents condition sensor in said stored contents; power driving and thereby transferring said sensor primarily horizontally through said contents and at a substantially uniform depth below the surface of said contents; using the surface of the contents for at least partially supporting the sensor so that the sensor elevation is coordinated with the content surface elevation to follow surface contour and maintain said depth as said sensor is driven; and producing a signal in response to change of condition of said contents sensed by said sensor.
Claim 3
Independent Claim
79 words
A method of monitoring condition of stored contents of a storage vessel comprising the steps of: locating contents condition sensor in said stored contents; power driving and thereby transferring said sensor through said contents; producing a signal in response to change of condition of said contents sensed by said sensor; and moving a transmitter simultaneously with said sensor, and transmitting from said transmitter by wireless transmission information from said sensor to a stationary receiver for production of said signal.
Claim 4
Independent Claim
79 words
A method of monitoring condition of stored contents of a storage vessel comprising the steps of: locating contents condition sensor in said stored contents; power driving and thereby transferring said sensor through said contents; producing a signal in response to change of condition of said contents sensed by said sensor; and moving a transmitter simultaneously with said sensor, and transmitting from said transmitter by wireless transmission information from said sensor to a stationary receiver for production of said signal.
Claim 5
Dependent Claim
15 words
The method of claim 2 wherein the step of transmission is done at radio frequency.
Claim 6
Dependent Claim
46 words
In a storage vessel having stirring apparatus therein, and wherein the stirring apparatus includes hanger means above the material stored in the vessel, the improvement comprising: a probe mounted to said hanger means; and a sensor mounted to said probe for reception in the stored material.
Claim 7
Dependent Claim
46 words
In a storage vessel having stirring apparatus therein, and wherein the stirring apparatus includes hanger means above the material stored in the vessel, the improvement comprising: a probe mounted to said hanger means; and a sensor mounted to said probe for reception in the stored material.
Claim 8
Dependent Claim
53 words
The improvement of claim 4 wherein: said hanger means include a stationary portion and a movable portion; an information sending means is coupled to said sensor and mounted on said movable portion; and an information receiver means is mounted on said stationary portion and operable to wirelessly receive information from said sending means.
Claim 9
Dependent Claim
54 words
The improvement of claim 4 wherein: said hanger means include a stationary portion and a movable portion; and said movable portion includes an arm rotatable in said vessel generally about a vertical axis, and a carriage mounted on said arm and movable radially on said arm, in and out with respect to said axis.
Claim 10
Dependent Claim
13 words
The improvement of claim 6 wherein: said probe is mounted to said carriage.
Claim 11
Dependent Claim
46 words
The improvement of claim 7 wherein: said carriage has at least one auger extending vertically downward from it and powered to auger stored material upwardly in the vessel; said sensor being adjacent said auger to sense the temperature of said material moved upwardly by said auger.
Claim 12
Dependent Claim
42 words
The improvement of claim 8 wherein: said one auger is one of a pair of augers mounted on said carriage, and said sensor is located in a plane tangent a circle about said axis and between the two augers of the pair.
Claim 13
Dependent Claim
81 words
The improvement of claim 4 wherein said probe includes: a first arm having a proximal end portion pivotally mounted to said hanger means to pivot in a substantially vertical plane; and a second arm having a proximal end portion pivotally mounted to a distal end portion of said first arm to pivot in a substantially vertical plane; and a tube secured to a distal end portion of said second arm, said sensor being located in a distal end of said tube.
Claim 14
Dependent Claim
40 words
The improvement of claim 10 wherein said probe includes: a sled between the distal end of said second arm and the distal end of said tube for supporting said second arm on the surface of material stored in the vessel.
Claim 15
Dependent Claim
110 words
The improvement of claim 11 wherein: said probe further includes a control arm pivotally mounted to said hanger means and to said second arm, with the pivot axis of said control arm establishing a parallelogram, with a portion of said second arm being a substantially vertical link of said parallelogram, and a portion of said hanger means being a substantially vertical second link of said parallelogram, whereby said second arm and tube are maintained in a substantially vertical attitude while the distal end portion of said first arm is swingable vertically to accommodate resting of said sled on said surface at varying surface elevations of said material in said vessel.
Claim 16
Dependent Claim
20 words
The improvement of claim 12 wherein: said hanger means includes means for driving said first arm horizontally in said vessel.
Claim 17
Dependent Claim
33 words
The improvement of claim 13 wherein: said driving means include a stirrer mounting carriage having a stirrer extending downward into said material, said second arm extending substantially parallel and adjacent to said stirrer.
Claim 18
Dependent Claim
28 words
The improvement of claim 14 wherein: said stirrer is a powered auger operable, when powered, to move material upward around said sensor and to the said material surface.
Claim 19
Dependent Claim
28 words
The improvement of claim 4 and further comprising slip ring means coupling information from said sensing means to a readout means on a stationary portion of said vessel.
Claim 20
Dependent Claim
35 words
The improvement of claim 16 and wherein: said storage vessel is generally cylindrical; said hanger means is located near the top of the storage vessel; and said probe is driven in a generally curvilinear pattern.
