ing troughs 28. The sealing troughs 28 are ?lled
I with a heavy sealing liquid or substance 30. For
example, a heavy grease. This grease forms a
perfect air seal betweenthe suction box l5 and
the furnace unit IS.
The annular furnace unit 16 is provided with
several spokes 32‘ by which it is connected with an axial hub 33. This hub 33 is mounted upon
vertical shaft 34 which is provided with a gear 60
35 engaged by a pinion 36 ofa speed reduction
transmission 31 which is connected and driven by
an electric motor 38. The transmission 31 is so

of parallel upwardly and forwardly extending
arms 64.
The arms 64 are supported'on their
top ends upon rods 65. These rods 65 are sup
ported on their inner ends upon the support bar
54. At their outer ends, they are supported on
brackets 66. The arrangement is such that when
the ignition hood I9 is forced rcarwards it will .
also move upwards. The front and back edges
of the ignition hood 19 are formed with ?ared
portions 61. These ?ared portions 61 assist the
ignition hood 19 in properly sitting upon the tops
of the pan sections 11. The front ?ared portion
61 also acts as a. cam to force the ignition hood
designed that the furnace unit l6 makes one
complete revolution for each period of time re 65 upwards, when the ignition hood is forced rear
wards. A cylinder 68 provided with a piston rod
quired to sinter the material in the pan sections
