Abstract
Abstract Sampling of liquids to isolate discrete samples is accomplished by flowing the liquid through an intermittently actuated diverter from which successive samples flow to different collection locations through appropriate distribution means including a distributor arm movable stepwise to discharge into separate collector lines. Timed actuation of the diverter and distributor is provided by electrical relays and related controls.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
159 words
In a liquid-sampling apparatus, structural provision for operating in a discrete sample mode and convertibly in a composite sample mode, comprising means for flowing liquid to be sampled past means for diverting samples of liquid therefrom, means for actuating the diverting means intermittently to effect diversion of liquid samples thereby, and means for distributing the diverted liquid samples to a multiplicity of collection locations in succession when operating in a discrete sample mode and to a single collection location when operating in a composite mode, the distributing means comprising a radial tube having an inlet at a central locus and having an outlet arcuately movable to a multiplicity of positions on the periphery of a circle about the central locus, and a multiplicity of conduits having their respective inlets arranged about the periphery of the circle underneath the positions of the outlet of the radial tube and having their respective outlets terminating above corresponding but rectilinearly arranged collection locations.
Claim 2
Dependent Claim
159 words
In a liquid-sampling apparatus, structural provision for operating in a discrete sample mode and convertibly in a composite sample mode, comprising means for flowing liquid to be sampled past means for diverting samples of liquid therefrom, means for actuating the diverting means intermittently to effect diversion of liquid samples thereby, and means for distributing the diverted liquid samples to a multiplicity of collection locations in succession when operating in a discrete sample mode and to a single collection location when operating in a composite mode, the distributing means comprising a radial tube having an inlet at a central locus and having an outlet arcuately movable to a multiplicity of positions on the periphery of a circle about the central locus, and a multiplicity of conduits having their respective inlets arranged about the periphery of the circle underneath the positions of the outlet of the radial tube and having their respective outlets terminating above corresponding but rectilinearly arranged collection locations.
Claim 3
Dependent Claim
106 words
In liquid-sampling apparatus, wherein successive samples of liquid are diverted from a body thereof, the improvement in means for distributing and collecting the samples individually comprising a multiplicity of conduits leading from successive locations on the periphery of a horizontal circle to corresponding but differently arranged collection locations therebelow, a radial tube located above the conduits and leading from a locus above the center of the circle to the periphery thereof and movable to position its peripheral end successively over the respective conduits, and removable means for supporting a multiplicity of collection vessels more closely spaced to one another than are the locations on such circle.
Claim 4
Dependent Claim
106 words
