Abstract
Abstract A sampling apparatus particularly for use at an offshore location. It relates in particular to a liquid specimen collector utilized in the monitoring of the quality of waste contaminated water which is being discharged at the offshore location. The apparatus includes guide means whereby a specimen or sample water collector can be lowered to a desired water depth. The water collector unit embodies a spring actuated container which is lowered from the water''s surface in a closed condition such as to acquire a liquid sample when actuated to an opened position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
131 words
Liquid sampler device for a marine structure positioned at an offshore body of water and including; elongated guide means disposed uprightly in said body of water, said elongated guide means having an upper end positioned adjacent to the water''s surface, and a lower end spaced downwardly from the latter, a liquid specimen capsule having a collector chamber, said capsule being operably carried within said elongated guide means and longitudinally movable therealong between upper and lower ends thereof, normally closed valve means in said specimen capsule communicated with said collector chamber, and being actuatable to an open position whereby to admit and retain a liquid in said chamber when said collector is lowered a desired distance into said elongated guide means, and means for moving said specimen capsule along said guide means.
Claim 2
Dependent Claim
131 words
Liquid sampler device for a marine structure positioned at an offshore body of water and including; elongated guide means disposed uprightly in said body of water, said elongated guide means having an upper end positioned adjacent to the water''s surface, and a lower end spaced downwardly from the latter, a liquid specimen capsule having a collector chamber, said capsule being operably carried within said elongated guide means and longitudinally movable therealong between upper and lower ends thereof, normally closed valve means in said specimen capsule communicated with said collector chamber, and being actuatable to an open position whereby to admit and retain a liquid in said chamber when said collector is lowered a desired distance into said elongated guide means, and means for moving said specimen capsule along said guide means.
Claim 3
Dependent Claim
49 words
In a liquid sampler device as defined in claim 1 wherein; said elongated guide means comprises a rigid walled member having at least a portion of said rigid wall disposed contiguous with said liquid capsule to slidably guide the latter during movement of said capsule along said guide means.
Claim 4
Dependent Claim
33 words
In a liquid sampler device as defined in claim 1 wherein; said elongated guide means comprises a closed conduit, the walls of said conduit defining a passage for slidably guiding said capsule therethrough.
Claim 5
Dependent Claim
43 words
In a liquid sampler device as defined in claim 1 wherein; said elongated guide means comprises a rigid walled cylindrical conduit having the inner surface of said cylindrical wall disposed contiguous with said liquid capsule to slidably guide the latter along said conduit.
Claim 6
Dependent Claim
56 words
In a liquid sampler device as defined in claim 1 wherein; said elongated guide means includes actuating means disposed at the capsule lower end, said actuating means being positioned to engage said elongated guide means whereby to actuate said valve means to an open position when the capsule is lowered to said guide means lower end.
Claim 7
Dependent Claim
32 words
In a liquid sampler device as defined in claim 1 wherein; said normally closed valve means includes biasing means engaging said valve means and urging the latter into said normally closed position.
Claim 8
Dependent Claim
27 words
In a liquid sampler device as defined in claim 6 wherein; said biasing means is adjustable to vary the degree of biasing urged against said valve means.
Claim 9
Dependent Claim
36 words
In a liquid sampler device as defined in claim 6 wherein; said biasing means includes spring means carried on said capsule and being adjustable to vary the degree of closing bias exerted against said valve means.
Claim 10
Dependent Claim
87 words
In a liquid sampler device as defined in claim 6 wherein; said normally closed valve means includes a valve stem operably disposed in said collector chamber, and carrying at least one valve seat thereon adapted to engage a corresponding seat in said collector whereby to regulate said valve means, a shoe portion of said valve stem depending from the capsule lower end whereby to longitudinally displace said valve stem and adjust said valve means to the open position when said stem shoe portion engages said actuating member.
