Abstract
Abstract A pair of pumps driven by a common motor draw in ambient seawater through e and expel it through the other to following electronic instrumentation. Coupled between the pumps, a rapidly rotating disk receives the flow of seawater and radially dissipates it in a multitude of separated droplets. The droplets are collected in a reservoir and the second pump expels it to the instrumentation. Where the flowing seawater is separated into droplets by the rapidly spinning disk, a break is created in the electrical conductivity continuity so that the following electronic instrumentation is not influenced by possible electrical potentials in the ambient seawater.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
113 words
An apparatus for breaking the electrical conductivity continuity in a fluid flowing from a source to instrumentation comprising: drivable impelling means coupled to the source for impelling the fluid therefrom; means coupled to the impelling means for radially dissipating the fluid in the form of a multitude of separated droplets; means arranged to collect the multitude of separated droplets for coalescing them into a reservoir of fluid; drivable expelling means coupled to the reservoir of fluid for expelling the fluid therefrom and to the instrumentation; and means connected to the drivable impelling means and drivable expelling means for synchronously driving them thereby matching the flow rates to and from the reservoir of fluid.
Claim 2
Independent Claim
113 words
An apparatus for breaking the electrical conductivity continuity in a fluid flowing from a source to instrumentation comprising: drivable impelling means coupled to the source for impelling the fluid therefrom; means coupled to the impelling means for radially dissipating the fluid in the form of a multitude of separated droplets; means arranged to collect the multitude of separated droplets for coalescing them into a reservoir of fluid; drivable expelling means coupled to the reservoir of fluid for expelling the fluid therefrom and to the instrumentation; and means connected to the drivable impelling means and drivable expelling means for synchronously driving them thereby matching the flow rates to and from the reservoir of fluid.
Claim 3
Dependent Claim
20 words
An apparatus according to claim 1 further including: means connected to the drivable impelling means for receiving the fluid therefrom.
Claim 4
Dependent Claim
20 words
An apparatus according to claim 1 further including: means coupled to the radially dissipating means for imparting rotational motion thereto.
Claim 5
Dependent Claim
26 words
An apparatus according to claim 3 in which the rotational motion imparting means is a motor localed in a fluid-tight housing disposed in the fluid reservoir.
Claim 6
Dependent Claim
21 words
An apparatus according to claim 4 in which the rotational motion imparting means is inductively coupled to the radially dissipating means.
Claim 7
Dependent Claim
24 words
An apparatus according to claim 5 in which the radially dissipating means is a disk rotatably mounted on the outside of the fluid-tight housing.
Claim 8
Dependent Claim
31 words
An apparatus according to claim 6 in which the synchronously driving means is a motor having its drive shaft connected for simultaneously driving the drivable impelling means and drivable expelling means.
Claim 9
Dependent Claim
28 words
An apparatus according to claim 7 in which the drivable impelling means and drivable expelling means are a pair of pump heads having a substantially identical pumping capability.
Claim 10
Dependent Claim
37 words
An apparatus according to claim 8 in which the receiving means is a length of tubing coaxially mounted on the disk and having a number of openings near the surface of the disk for feeding fluid therethrough.
Claim 11
Dependent Claim
34 words
An apparatus according to claim 9 in which the flow rate of the fluid is controlled by the pair of pump heads to permit an effective radial dissipation of the fluid by the disk.
