Abstract

A chemical transfer coupler including a chemical flow chamber and a probe are provided. The probe extends through the chemical flow chamber and defines a first recessed slot. The first recessed slot extends helically along the probe.

First claim

What is claimed is:

1 . A chemical transfer coupler comprising:
a chemical flow chamber; and a probe extending through the chemical flow chamber, the probe defining a first recessed slot, the first recessed slot extending helically along the probe.

2 . The chemical transfer coupler of claim 1 , wherein the probe defines a second recessed slot extending helically along the probe.

3 . The chemical transfer coupler of claim 2 , wherein
the probe includes a probe end fitting, and one or more of the first recessed slot and the second recessed slot extend helically along the probe end fitting.

4 . The chemical transfer coupler of claim 3 , wherein
the probe end fitting has a first end and a second end, and one or more of the first recessed slot and the second recessed slot extend helically from the first end to the second end.

5 . The chemical transfer coupler of claim 3 , wherein
the probe end fitting has a first end and a second end, and one or more of the first recessed slot and the second recessed slot extend helically along only a portion of the probe end fitting between the first end and the second end.

6 . The chemical transfer coupler of claim 2 , wherein
the probe includes a shaft, and one or more of the first recessed slot and the second recessed slot extend helically along the shaft.

7 . The chemical transfer coupler of claim 2 , wherein the first recessed slot and the second recessed slot extend helically along the probe in a first rotational direction.

8 . The chemical transfer coupler of claim 2 , wherein
the first recessed slot extends helically along the probe in first rotational direction, and the second recessed slot extends helically along the probe in second rotational direction.

9 . The chemical transfer coupler of claim 2 , wherein the first recessed slot is positioned on the probe opposite the second recessed slot.

10 . The chemical transfer coupler of claim 2 , wherein the first recessed slot is substantially identical to the second recessed slot in shape.

11 . The chemical transfer coupler of claim 2 , wherein the first recessed slot and the second recessed slot are mirror images of one another in shape.

12 . The chemical transfer coupler of claim 1 , wherein a width dimension of the first recessed slot is greater than a depth dimension of the first recessed slot.

13 . The chemical transfer coupler of claim 1 , wherein a depth of the first recessed slot is tapered along a length of the first recessed slot.

14 . The chemical transfer coupler of claim 1 , wherein a depth of the first recessed slot is substantially uniform along the probe.

15 . A chemical transfer coupler comprising:
a chemical flow chamber; and a probe extending through the chemical flow chamber, the probe defining
a first recessed slot having a first upper end and a first lower end, and
a second recessed slot having a second upper end and a second lower end, wherein the first recessed slot and the second recessed slot extend helically along the probe, and the first lower end and the second lower end converge toward one another.

16 . The chemical transfer coupler of claim 15 , wherein the first upper end and the second upper end are separated by a first probe circumference portion, the first lower end and the second lower end are separated by a second probe circumference portion, and the first probe circumference portion is larger than the second probe circumference portion.

17 . The chemical transfer coupler of claim 15 , wherein one or more of the first recessed slot and the second recessed slot are defined in a probe end fitting of the probe.

18 . The chemical transfer coupler of claim 15 , wherein the first recessed slot and the second recessed slot converge to at least partially overlap one another at the first lower end and the second lower end.

19 . A chemical transfer coupler comprising:
a chemical flow chamber; and a probe extending through the chemical flow chamber, the probe defining a plurality of recessed slots that extend helically along the probe in a first rotational direction.

20 . The chemical transfer coupler of claim 19 , wherein the plurality of recessed slots are evenly spaced apart from one another about the probe.
