The conduit defines a conduit passageway having a conduit inlet and a conduit outlet.

The outer conduit extends beyond the inner conduit.

An inner conduit flowpath is defined within the inner conduit and an outer conduit flowpath is defined between the inner conduit and the outer conduit.

The construction includes an inner conduit (22i) and an outer conduit (22a) surrounding the inner conduit.

The sampling conduit is sized in relation to the conduit to cause isokinetic withdrawal of fluid from said conduit into said sampling conduit.

A pneumatically driven pump is connected with the conduit for pumping fluid into the conduit.

A pneumatically driven pump is connected with the conduit for pumping fluid into the conduit.

A bypass duct (4) bypasses an introduction duct (21) of the air supply duct (2) and the outlet duct (8).

The first inlet duct and the second inlet duct merge into a common duct.

The exhaust gas cleaning system comprises an inlet duct (10), an outlet duct (20), and a transition duct (30) connecting the inlet duct to the outlet duct.

Each induction duct (28) has a duct inlet (30), a duct outlet (32) and a duct body (34) interposed between the duct inlet (30) and the duct outlet (32).

An outer duct (16) having an outer duct cross-sectional area is sealingly connected to the inlet duct (20) and the outlet duct (18), while separating the inlet duct (20) and the outlet duct (18).

The tail pipe is parallel to the head pipe.

The other end of the exhaust pipe is connected to a heat exchanger, and a branch pipe (6), which extends transversely to the exhaust pipe, is connected to the exhaust pipe.

The pipe includes a proximal pipe end (12) and a flared end region (16).

The supply pipe and the discharge pipe may be combined in a coaxial pipe with the supply pipe arranged in the centre and the discharge pipe enveloping the supply pipe.

The main body has, at an outer surface thereof, an inlet pipe and an outlet pipe, and the outlet pipe is arranged underneath the inlet pipe.

The circulation flow passage (C) is provided in the vicinity of either the supply air flow passage (A) or the discharge air flow passage (B).

The liquid passsage is connected to the vacuum passage.

The housing includes a first passageway disposed about the probe and second passageway disposed about the first passageway.

The first oil passage intersects the second oil passage.

The passageways define a delivery conduit and a return conduit.

The lead extraction device is thereby tracked over the lead.

The first conduit may be enclosed within a first portion of the second conduit, and the third conduit may be enclosed within a second portion of the second conduit thus forming two coaxial tubes.

The machine includes a conduit and an inlet tube connected to the conduit for providing the conduit with hard and soft material.

The distal portion of the injection tube terminates just inside of the aspiration tube and directs the heated fluid through an orifice in the wall of the aspiration tube opposite the injection tube.

A partition wall (5) in the middle of the rear flue (2) divides the rear flue (2) into a front rear flue (3) and a back rear flue (4).

The device comprises a branch-off (32) that divides the flue (3) into a main duct (30) and a by-pass pipe (31 ), and a purifier assembly (11 ) positioned along said by-pass pipe (31 ).

The delivery line assembly has a liquid line, a vapor line, and a delivery line.

The device has a gas flow circuit comprising an oscillating line (14), a patient line (25) and an exhalation or a return line (67).

A gas supply line (8) is connected to the oscillating line, and a patient line (25) is connected to a second end of the oscillating line.

The seed metering line (812) has an outer seed line (816) and an inner seed line (826), where the inner seed line (826) is detachably arranged in the outer seed line (816).

The conduit includes a conduit flow channel that extends longitudinally along a centerline between a first conduit end and a second conduit end.

The medium can be led through the channel.

One side of each pressure channel communicates with a supply channel and the other side communicates with a discharge channel.

The injector further includes a first flow channel extending through the body, and a second flow channel extending through the body that is separate from the first flow channel and electrically isolated from the first flow channel.

At least one of the inlet channel and the outlet channel extends through the bearing-receiving element.

A synthetic resin pipe insert (1) for insertion in an existing pipe (6) or for use in the manufacture of new pipe to form a multi-channel pipe.
