low refrigeration temperature within the entirety of the
insulated sample chamber (13) to prevent deterioration of the
fluid sample, i.e., in the space or "first cooling volume"
physically located within the confines of the cooling coils
themselves which is occupied by the sample storage bottle (16),
as well as in the space or "second cooling volume" located, for
example, above the storage bottle and cooling coils (41) and
adjacent the lower end of inlet conduit (28) through which the
fluid sample must pass, as seen in Figure 2 of Gillard. Thus,
although Gillard teaches cooling only the insulated sample
chamber (13), the examiner has correctly determined that the
chamber (13) is made up of two contiguous volumes, each of which
is clearly cooled by the cooling coils (41). Moreover, the two
volumes are operative to cool the fluid sample both during its
passing from the conduit (28) to the storage bottle (16), i.e.,
within the second cooling volume, and once housed within the
storage bottle in the first cooling volume.
In a similar fashion, when cooling coils like those seen at
(41) of Gillard are used in the lower section or sample chamber
(13) of Singer's fluid sewage sampler so as to gain the advantage
of preventing putrefaction and deterioration of the fluid sample,
