Abstract: Abstract of the Disclosure A shingle handling and squaring device (18) is disposed between a sheet shingler (5) and stacker (9) and mounted above a stack infeed conveyor (19).  The device includes a pair of side carriages (23,24), each of which carries a pair of freely rotatable longitudinally in-line tamping rollers or wheels (29-32), the peripheries of which are adapted to engage an edge of the traveling sheet material (6).  The wheels are mounted for rotation about generally vertical but slightly inclined axes (48) and have tapered peripheries (51) so that the wheels nevertheless present truly vertical faces to the sheet material.  The wheels are counterbalanced (56).  In addition, when the stacker infeed nip roll (17) is raised by the entry of shingled sheets, a device (57-60) is provided to release the nip roll from the sheets to prevent binding.  While the nip roll is released, the side carriages are moved transversely inwardly toward the sheet edges in a unique manner such that even off-center sheets are automatically and properly engaged and squared by the tamping wheels before the stacker infeed nip roll is re-engaged with the sheets.  Furthermore, an automatic jam detection and releasing arrangement (72,73,57) is associated with the upstream wheels (29,31) and which is responsive to excessive upward wheel lifting about a transverse axis (45).

Filed: 1990-08-27
Granted: 1993-07-27
Abstract: Disclosed is a plasma reactor for use to treat ores or other material at a very high temperature in order to physically or chemically transform the same. The reactor comprises a vertical, electrically insulated sleeve disposed at the upper end with a hollow torch of a conventional structure, for use to generate a plasma column. A gas is tangentially injected into the torch to create a vortex inside the same. The material to be treated is dropped, in powder form, vertically downward inside the sleeve from the upper end thereof, beside the hollow torch, so as to form a substantially uniform cylindrical curtain of particles falling down into the sleeve. The particles that are centrifugally projected against the internal wall of the sleeve by the vortex escaping from the hollow torch, entirely cover the internal wall of the sleeve and shield, while simultaneously being treated by heat generated by the plasma arc column. The reactor further comprises a crucible positioned under the sleeve to collect the treated particles in molten form, which drip down from the sleeve at the lower end thereof. The plasma column may be generated by the hollow torch exclusively, when the reactor is intended to be used in a non-transferred arc mode. The reactor may also be used in a transferred arc mode. In such a case, the arc is transferred to a melt contained in the crucible. Another electrode is provided for this purpose at the bottom of this crucible, and is electrically connected to the power supply.

Title: Industrial furnace with improved heat transfer
Inventor: HOETZL MAX
IPC: C21D1/34
Filed: 1990-12-19
Granted: 2000-02-22
Abstract: An improved industrial furnace employing a new and unique heat transfer arrangement is disclosed. The furnace is a closed end cylindrical chamber with a circular, concentrically positioned plate dividing one side of the furnace into a fan chamber containing a fan and the other side of the furnace into a heat treat chamber containing the work.      The plate has a central under-pressure opening and its outer circular edge is spaced from the cylindrical wall to define an annular space which is non-orificing. Fan rotation in the fan chamber produces an annulus of wind mass swirling at high circumferential speed which axially travels through the non-orificing space towards the closed end of the heat treat chamber at slow speed. Heating elements extend through the non-orificing space into the heat transfer chamber and are constantly impinged by the swirling annulus wind mass to effect good heat transfer therewith. The under-pressure opening causes the heated wind to contact the work before it is drawn into the under-pressure opening for recirculation.      An incineration track is provided in the furnace insulation for incinerating the furnace flue products while also heating the wind mass.
