Abstract
Abstract A sampling apparatus for automatically sampling solids at regulated time intervals from a conduit carrying said solids comprising a base member affixed over an opening in the conduit and having a sampling tube extending through the member and the conduit and into the path of guide vanes mounted on said base member. The sampling tube has a butterfly valve to form a sampling chamber in the upper end and the lower end communicates into a sample accumulator. The apparatus has a pneumatic system with a line to purge the sample chamber before the sampling operation and lines to activate a power cylinder to operate the butterfly valve, and this system is controlled by an electrical system for timing and sequential activation of the components to obtain and transfer samples to the accumulator.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
161 words
An apparatus for automatically sampling solids from a gravity conveyor conduit which comprises: a base member adapted to be affixed in an opening of said conveyor conduit, said member having an aperture; a plurality of guide vanes affixed to said base member above said aperture on the side of said base member communicating with the interior of said conveyor conduit; a sampler tube having a first end affixed through the aperture of said base member with valve means forming a sample chamber in the upstream end adapted to communicate through said tube and the second end of said tube extending into a sample accumulator; a sample chamber purge means connected to said chamber; a power means affixed to said base member on the side exterior of said conveyor conduit and connected to the valve means in said sampler tube; an activation means communicating with said power means; and a control means for said sample chamber purge means and said activation means.
Claim 2
Independent Claim
161 words
An apparatus for automatically sampling solids from a gravity conveyor conduit which comprises: a base member adapted to be affixed in an opening of said conveyor conduit, said member having an aperture; a plurality of guide vanes affixed to said base member above said aperture on the side of said base member communicating with the interior of said conveyor conduit; a sampler tube having a first end affixed through the aperture of said base member with valve means forming a sample chamber in the upstream end adapted to communicate through said tube and the second end of said tube extending into a sample accumulator; a sample chamber purge means connected to said chamber; a power means affixed to said base member on the side exterior of said conveyor conduit and connected to the valve means in said sampler tube; an activation means communicating with said power means; and a control means for said sample chamber purge means and said activation means.
Claim 3
Dependent Claim
39 words
The apparatus of claim 1 wherein the first end of said sampler tube is cut at an angle to have a substantially horizontal cross section with the shortest side of said tube being mounted flush with said base member.
Claim 4
Dependent Claim
18 words
The apparatus as set forth in claim 1 wherein the sampler tube valve means is a butterfly valve.
Claim 5
Dependent Claim
35 words
The apparatus of claim 1 wherein the power means is a pneumatic power cylinder affixed to said base member with the piston thereof having a rod connected to actuate the valve in said sampler tube.
Claim 6
Dependent Claim
52 words
The apparatus of claim 1 wherein the sample chamber purge means is a pneumatic line extending from a pressurized gas source through the wall of the said sampler tube into the lower portion thereof with said pneumatic line having a pressure regulator upstream of a valve controlled by a single-stage solenoid means.
Claim 7
Dependent Claim
30 words
The apparatus of claim 5 wherein the activation means is a pneumatic line extending from a compressed gas source through a pressure regulator and valve means to said power means.
Claim 8
Dependent Claim
37 words
The apparatus of claim 6 wherein the control means are electrical lines extending from a timing means to operation means for the valve means of said activation means and the valve of said sample chamber purge means.
Claim 9
Dependent Claim
11 words
The apparatus of claim 7 wherein said operation means are solenoids.
Claim 10
Dependent Claim
26 words
The apparatus of claim 7 wherein the valve means of said activation means is a two-way valve and the operation means thereof is a double-stage solenoid.
Claim 11
Dependent Claim
25 words
The apparatus oF claim 7 wherein the timing means is an electronic timer preset to sequentially operate to transmit electrical signals to said control means.
