Abstract
Abstract A fluid discharge device comprises a nozzle. The nozzle is constructed from a first jewel such as a corundum or diamond. An aggregation of ions formed from a second material such as nickel, titanium or chromium are implanted onto a surface of the nozzle, whereby a useful lifetime of the nozzle with a fluid passing through the nozzle under high pressure, is increased.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
56 words
A fluid discharge apparatus comprising: a nozzle, having a surface, the nozzle being constructed from a jewel; and an aggregation of ions, formed from a second material, different from said jewel, which are implanted onto the surface, whereby a useful lifetime of the nozzle, with a fluid passing through the nozzle under high pressure, is increased.
Claim 2
Dependent Claim
56 words
A fluid discharge apparatus comprising: a nozzle, having a surface, the nozzle being constructed from a jewel; and an aggregation of ions, formed from a second material, different from said jewel, which are implanted onto the surface, whereby a useful lifetime of the nozzle, with a fluid passing through the nozzle under high pressure, is increased.
Claim 3
Dependent Claim
13 words
The apparatus as described in claim 1, wherein the second material includes nickel.
Claim 4
Dependent Claim
13 words
The apparatus as described in claim 1, wherein the second material includes titanium.
Claim 5
Dependent Claim
13 words
The apparatus as described in claim 1, wherein the second material includes chromium.
Claim 6
Dependent Claim
13 words
The apparatus as described in claim 1, wherein the jewel is a diamond.
Claim 7
Dependent Claim
13 words
The apparatus as described in claim 1, wherein the jewel is a corundum.
Claim 8
Dependent Claim
13 words
The apparatus as described in claim 6, wherein the jewel is a sapphire.
Claim 9
Dependent Claim
28 words
The apparatus as described in claim 1, wherein the useful lifetime is determined by a retention of a usable fishline stream length produced by fluid exiting the nozzle.
Claim 10
Dependent Claim
35 words
The apparatus as described in claim 1, further comprising: an orifice formed in the nozzle, wherein the useful lifetime is determined by a retention of surface geometry of the entrance and/or passage of the nozzle.
Claim 11
Dependent Claim
64 words
A fluid discharge assembly comprising: a nozzle, having a surface, the nozzle being constructed from a jewel; an aggregation of ions, formed from a second material, different from the jewel, which are implanted onto the surface, whereby a useful lifetime of the nozzle, with a fluid passing through the nozzle under high pressure, is increased; and a nozzle mount for securely retaining the nozzle.
Claim 12
Dependent Claim
64 words
A fluid discharge assembly comprising: a nozzle, having a surface, the nozzle being constructed from a jewel; an aggregation of ions, formed from a second material, different from the jewel, which are implanted onto the surface, whereby a useful lifetime of the nozzle, with a fluid passing through the nozzle under high pressure, is increased; and a nozzle mount for securely retaining the nozzle.
Claim 13
Dependent Claim
45 words
A fluid discharge apparatus comprising: a nozzle, having a surface including imperfections, the nozzle being constructed from jewel; and an aggregation of ions, formed from a second material, different from jewel, which are implanted onto the surface, whereby the effects of the imperfections are decreased.
Claim 14
Dependent Claim
45 words
A fluid discharge apparatus comprising: a nozzle, having a surface including imperfections, the nozzle being constructed from jewel; and an aggregation of ions, formed from a second material, different from jewel, which are implanted onto the surface, whereby the effects of the imperfections are decreased.
