Abstract
Abstract A fluid delivery system for degrading valuable items in the event on an attack is provided. A piston 30 is disposed within a cylinder 2 . On demand gas under pressure can be admitted into the cylinder 2 so as to urge the piston to move towards an outlet 8 , thereby expelling fluid 4 irrespective of the orientation of the delivery system.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
59 words
1 . A fluid delivery system comprising: a first cylinder having an outlet and containing fluid; a piston in substantially fluid sealed sliding arrangement within the cylinder; and supply means for the selective supply of gas under pressure into the first cylinder so that the piston is urged towards the outlet and the fluid is ejected from the outlet.
Claim 2
Dependent Claim
59 words
1 . A fluid delivery system comprising: a first cylinder having an outlet and containing fluid; a piston in substantially fluid sealed sliding arrangement within the cylinder; and supply means for the selective supply of gas under pressure into the first cylinder so that the piston is urged towards the outlet and the fluid is ejected from the outlet.
Claim 3
Dependent Claim
45 words
2 . A fluid delivery system as claimed in claim 1 , wherein the cylinder has an inlet and the means for the selective supply of gas under pressure to the inlet comprises a pressurized gas reservoir and electronically activated means for opening the reservoir.
Claim 4
Dependent Claim
22 words
3 . A fluid delivery system as claimed in claim 2 , wherein the pressurized gas reservoir contains pressurized carbon dioxide gas.
Claim 5
Dependent Claim
21 words
4 . A fluid delivery system as claimed in claim 1 , wherein the outlet is connected to a spray bar.
Claim 6
Dependent Claim
29 words
5 . A fluid delivery system as claimed in claim 1 , further comprising a burst disc in a fluid delivery path following the outlet of the first cylinder.
Claim 7
Dependent Claim
77 words
6 . A fluid delivery system as claimed in claim 1 , further comprising a second cylinder containing fluid and having an inlet and an outlet, a second piston in substantially fluid sealed sliding engagement therein, and means for the selective supply of gas to the inlet of the second cylinder, wherein gas under pressure is introduced at the inlet, so that the piston is urged towards the outlet and the fluid is ejected from the outlet.
Claim 8
Dependent Claim
27 words
7 . A fluid delivery system as claimed in claim 6 , wherein the first and second cylinders share common means for the selective supply of gas.
Claim 9
Dependent Claim
27 words
8 . A fluid delivery system as claimed in claim 6 , wherein a common fluid delivery path follows the outlet of the first and second cylinders.
Claim 10
Dependent Claim
21 words
9 . A fluid delivery system as claimed in claim 6 , wherein the first and second cylinders contain different fluids.
Claim 11
Dependent Claim
42 words
10 . A fluid delivery system as claimed in claim 6 , further comprising at least two relatively moveable sections, wherein the contents of a cylinder can be accessed by moving at least one of the sections relative to the other sections.
Claim 12
Dependent Claim
26 words
11 . A fluid delivery system as claimed in claim 10 , wherein the fluid in a cylinder is further contained within a removable fluid container.
Claim 13
Dependent Claim
27 words
12 . A fluid delivery system as claimed in claim 11 , wherein the piston contained within a cylinder is further contained within the removable fluid container.
Claim 14
Dependent Claim
69 words
13 . A media protection system comprising: a media container; and a fluid delivery system comprising (i) a cylinder having an outlet and containing fluid, (ii) a piston in substantially fluid sealed sliding arrangement within the cylinder, and (iii) supply means for the selective supply of gas under pressure into the cylinder so that the piston is urged towards the outlet and the fluid is ejected from the outlet.
Claim 15
Dependent Claim
69 words
13 . A media protection system comprising: a media container; and a fluid delivery system comprising (i) a cylinder having an outlet and containing fluid, (ii) a piston in substantially fluid sealed sliding arrangement within the cylinder, and (iii) supply means for the selective supply of gas under pressure into the cylinder so that the piston is urged towards the outlet and the fluid is ejected from the outlet.
Claim 16
Dependent Claim
20 words
14 . A media protection system as claimed in claim 13 , wherein the media container includes a cash cassette.
