Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
115 words
A hand-held probe for obtaining information about the kind and number of small particulates in a large volume of fluid standing or slowly circulating in a container comprising: an ultrasonic transmitter-receiver having a solid concave lens, said transmitter-receiver being disposed in a protective sheath to shield the transmitter-receiver from the fluid, said sheath being positioned on the end of a rod whereby said probe can be directed by hand to various locations in the fluid including the corners of the container so that said transmitter-receiver can direct its ultrasonic energy through said concave lens and into the adjacent fluid and thereby detect the presence of the small particulates by detecting the energy reflected from them.
Claim 2
Dependent Claim
115 words
A hand-held probe for obtaining information about the kind and number of small particulates in a large volume of fluid standing or slowly circulating in a container comprising: an ultrasonic transmitter-receiver having a solid concave lens, said transmitter-receiver being disposed in a protective sheath to shield the transmitter-receiver from the fluid, said sheath being positioned on the end of a rod whereby said probe can be directed by hand to various locations in the fluid including the corners of the container so that said transmitter-receiver can direct its ultrasonic energy through said concave lens and into the adjacent fluid and thereby detect the presence of the small particulates by detecting the energy reflected from them.
Claim 3
Dependent Claim
16 words
The probe of claim 1 wherein said protective sheath comprises a casing for holding said transmitter-receiver.
Claim 4
Dependent Claim
18 words
The probe of claim 1 wherein said rod carries a cable, said cable being attached to said transmitter-receiver.
Claim 5
Dependent Claim
22 words
The probe of claim 1 wherein said lens directs ultrasonic energy beams through a lens opening in the end of said sheath.
Claim 6
Dependent Claim
78 words
A probe for obtaining information about a fluid comprising: an ultrasonic transmitter-receiver having a lens, said transmitter-receiver being disposed in a protective sheath, said sheath being positioned on the end of a rod whereby said probe can be directed to various locations in the fluid, said probe further comprising a pump mounted on said rod, said pump having an associated conduit through which said pump forces the fluid and across which said conduit said ultrasonic transmitter-receiver is directed.
Claim 7
Dependent Claim
78 words
A probe for obtaining information about a fluid comprising: an ultrasonic transmitter-receiver having a lens, said transmitter-receiver being disposed in a protective sheath, said sheath being positioned on the end of a rod whereby said probe can be directed to various locations in the fluid, said probe further comprising a pump mounted on said rod, said pump having an associated conduit through which said pump forces the fluid and across which said conduit said ultrasonic transmitter-receiver is directed.
