Abstract
Abstract Apparatus for the sampling of heavy fuel oil supplied to a ship as bunker fuel consists of a pipe section for oil flow containing a static vane mixer, and a positive displacement pump with its inlet communicating with the interior of the pipe section downstream of the mixer, together with a delay timer causing the pump to pump out a small quantity of oil at regular intervals into a receptacle where these extracted quantities accumulate progressively during the course of the bunkering period.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
177 words
Portable apparatus for sampling viscous oil delivered through a pipe from a supply to at least one receiving container on board a ship, comprising a portable structure, a positive displacement pump having an inlet and an outlet, an inlet duct for communicating the pipe interior with said pump inlet, a connector for attaching a sample collecting receptacle, a further duct connecting said pump outlet to said connector, drive means for said pump, and control means arranged to operate said drive means and hence said pump, to extract small quantities over the course of delivery and supply them to the collecting receptacle to accumulate therein, said pump, connector, further duct, drive means and control means being assembled to said structure, whereby the assembly thereof is portable as a self-contained unit for ready connection to and disconnection from the pipe so as to permit ready connection for use with said assembly disposed exteriorly of said pipe, and said inlet duct connecting said pipe interior to said pump inlet, and also to permit disconnection for storage during periods of nonuse.
Claim 2
Dependent Claim
177 words
Portable apparatus for sampling viscous oil delivered through a pipe from a supply to at least one receiving container on board a ship, comprising a portable structure, a positive displacement pump having an inlet and an outlet, an inlet duct for communicating the pipe interior with said pump inlet, a connector for attaching a sample collecting receptacle, a further duct connecting said pump outlet to said connector, drive means for said pump, and control means arranged to operate said drive means and hence said pump, to extract small quantities over the course of delivery and supply them to the collecting receptacle to accumulate therein, said pump, connector, further duct, drive means and control means being assembled to said structure, whereby the assembly thereof is portable as a self-contained unit for ready connection to and disconnection from the pipe so as to permit ready connection for use with said assembly disposed exteriorly of said pipe, and said inlet duct connecting said pipe interior to said pump inlet, and also to permit disconnection for storage during periods of nonuse.
Claim 3
Dependent Claim
32 words
Apparatus according to claim 1 wherein said control means comprises a delay timer to operate said drive means at regular intervals, said timer being adjustable to vary the duration of said intervals.
Claim 4
Dependent Claim
19 words
Apparatus according to claim 2 wherein said drive means is a pneumatic actuator and said control means is pneumatic.
Claim 5
Dependent Claim
43 words
Portable apparatus according to claim 1, wherein said portable structure comprises a casing enclosing at least said pump, said drive means and said control means, manually operable controls to start and stop said drive means being provided on the exterior of said casing.
Claim 6
Dependent Claim
42 words
In combination, portable apparatus according to claim 1, and a pipe section for incorporation into said pipe, the combination including means for connection of said inlet duct to the interior of said pipe section through a lateral opening in said pipe section.
Claim 7
Dependent Claim
28 words
The combination of claim 5 including means for mounting the portable apparatus on the pipe section with said inlet duct communicating with the interior of said pipe section.
Claim 8
Dependent Claim
36 words
The combination of claim 5 wherein a sampling tube projects into the interior of the pipe section and terminates at an open end facing the oil flow and spaced from the walls of the pipe section.
Claim 9
Dependent Claim
29 words
The combination of claim 5 further including a static vane mixer in said pipe section to mix liquid flowing therethrough, said lateral opening being downstream of said mixing means.
Claim 10
Dependent Claim
64 words
In combination, a ship having pipework to receive viscous oil from a supply and deliver it to at least one or more tanks on board the ship, portable apparatus according to claim 1, and a pipe section incorporated into said pipework, which section has a lateral opening for connection of said inlet duct to the interior of said pipe section through said lateral opening.
Claim 11
Dependent Claim
46 words
The combination of claim 9 wherein said pipework includes at least one connection point for attachment of a flexible hose from said supply, and a said pipe section proximate each said connection point, each said connection point and pipe section proximate thereto being exposed on deck.
