Abstract
Abstract An apparatus for detecting ultrasonic energy comprises a chamber, partially filled with a colored liquid, having two sides separated by spacing no greater than about 25 millimeters and having a transparent section allowing for visual observation of the height of the liquid therein. A method of detecting the energy level of a beam of ultrasonic energy being propagated through a fluid comprises positioning the apparatus in the fluid so that the beam of energy strikes the liquid at the surface thereof, whereby the beam generates a visible arc-shaped spray having an amplitude proportional to the energy level of the beam.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
99 words
An apparatus for detecting the energy level of a beam of ultrasonic energy being propagated through a fluid adjacent thereto, comprising a chamber having two sides separated by a spacing no greater than about 25 millimeters, the width and height of said sides being significantly greater than said spacing, said chamber being partially filled with a liquid and having a transparent section allowing for visual observation of the height of said liquid therein, the liquid having a viscosity lower than water and being disposed within said chamber so that the free surface of the liquid intersects said two sides.
Claim 2
Independent Claim
99 words
An apparatus for detecting the energy level of a beam of ultrasonic energy being propagated through a fluid adjacent thereto, comprising a chamber having two sides separated by a spacing no greater than about 25 millimeters, the width and height of said sides being significantly greater than said spacing, said chamber being partially filled with a liquid and having a transparent section allowing for visual observation of the height of said liquid therein, the liquid having a viscosity lower than water and being disposed within said chamber so that the free surface of the liquid intersects said two sides.
Claim 3
Dependent Claim
27 words
An apparatus as defined in claim 1 wherein said two sides are parallel plates of quartz separated by spacers sealed thereto to form a plurality of chambers.
Claim 4
Dependent Claim
20 words
An apparatus as defined in claim 2 wherein said two plates are separated by a spacing of approximately 5 millimeters.
Claim 5
Dependent Claim
31 words
An apparatus as defined in claim 3 wherein said two plates are rectangular and are glued together with spacers made of plastic to form two separate chambers, one above the other.
Claim 6
Dependent Claim
12 words
An apparatus ad defined in claim 1 wherein said liquid is colored.
Claim 7
Dependent Claim
12 words
An apparatus as defined in claim 5 wherein said liquid is freon.
Claim 8
Independent Claim
146 words
A method of detecting the energy level of a beam of ultrasonic energy being propagated through a fluid comprising: filling a chamber partially with a liquid, said chamber having two sides separated by a spacing no greater than about 25 millimeters and having a transparent section allowing for visual observation of the height of said liquid therein, the liquid having a viscosity lower than water and being disposed within said chamber so that the free surface of the liquid intersects said two sides, the sides having a width and height significantly greater than said spacing, and positioning said chamber in said fluid so that said beam of energy strikes said liquid at the surface thereof from a direction substantially parallel to the plane of said free surface, whereby said beam generates a visible arc-shaped spray having an amplitude proportional to the energy level of said beam.
Claim 9
Independent Claim
146 words
A method of detecting the energy level of a beam of ultrasonic energy being propagated through a fluid comprising: filling a chamber partially with a liquid, said chamber having two sides separated by a spacing no greater than about 25 millimeters and having a transparent section allowing for visual observation of the height of said liquid therein, the liquid having a viscosity lower than water and being disposed within said chamber so that the free surface of the liquid intersects said two sides, the sides having a width and height significantly greater than said spacing, and positioning said chamber in said fluid so that said beam of energy strikes said liquid at the surface thereof from a direction substantially parallel to the plane of said free surface, whereby said beam generates a visible arc-shaped spray having an amplitude proportional to the energy level of said beam.
Claim 10
Dependent Claim
16 words
A method as recited in claim 7 wherein said chamber is half-filled with a colored liquid.
Claim 11
Dependent Claim
12 words
A method as recited in claim 8 wherein said liquid is freon.
Claim 12
Dependent Claim
55 words
A method as recited in claim 7 wherein said two sides are parallel plates of quartz separated by quartz spacers fused thereto to form two separate chambers, one above the other, and positioned at an angle of about 60° with the surface of a chemical cleaning fluid disposed in a tank adapted for megasonic cleaning.
