Abstract: A B S T R A C T     A spout (1) for discharging the smelt from recovery boilers in pulp mills provided with a water cooler (2), the outlet end (3) of which is surrounded by a second cooler (4) with a narrow channel (8) through which water can be pressed  at  a high speed resulting in an intense cooling of the outlet end which brings about an increased life of the spout. This life can be additionally improved by in-creasing the area of the spout by making longitudinal grooves (5) in the inner jacket (6). As the intense cooler (4) can be stopped when the outlet end (3) has been so worn down that there is a risk of holes, the spout can be used still some time with the conventional cooling (2) alone up to a previously planned shut down.

Abstract: ABSTRACT OF THE DISCLOSURE         The present specification discloses a pyrometal-lurgical system for maintaining a material in a molten state and a method therefor, the system comprising a vessel for molten material, the vessel conceptually dividable into a number of substantially uniform cells.  A mechanical stirrer is provided for each such cell and is centered within the cell.  The stirrers are sized and driven at a rate so as to promote a uniform temperature and composition of the molten material and improved heat transfer between, and blending of, various constituents of molten material, while producing minimal erosion of the conventional re-fractory lining of the vessel.  Preferably, adjacent pairs of stirrers are driven with opposite rotational senses, thereby assuring reinforcing flow patterns at the cell boundaries.  Heating means (e.g., power electrodes) are provided at locations which do not substantially inter-fer with the flow patterns generated by the array of mechanical stirrers.

Abstract: ABSTRACT OF THE DISCLOSURE           A briquetting plant for hot briquetting particulate matter, such as mill waste containing a material that softens when heated, such as iron oxide, which includes a low tempera-ture tumbler type heat exchanger, an intermediate temperature tumbler type heat exchanger, a fluid bed furnace and a compactor, with the feed material being fed therethrough in succession.          The briquettes produced by the compactor are first fed from the outlet of the compactor into the intermediate temperature heat exchanger, for liberation of heat therein, separated from the feed material by a screen at the outlet of the intermediate temperature heat exchanger and from such screen transported into the low temperature heat exchanger for further imparting of heat to the feed material.  A-second screen is provided at the outlet of the low temperature heat exchanger for separating and discharging the briquettes in relatively cooled form.  The tumbler type heat exchangers are in-the form of a hollow cone having a wide included angle enclosed by a cover and slowly rotated about an inclined axis to provide intimate mixing of the components and uniform withdrawal of the mixture.  The heat exchangers are mounted at a low level and the screens are mounted at a high level with bucket type elevators in between and with the furnace and compactor being located at successive intermediate levels so that, except for the two bucket elevators, all of the flow in the plant takes place under action of gravity.  Wet and dry feed materials are separately handled, with means being provided for conveying the dry feed directly to the second heat exchanger.

Abstract: Abstract A microwave cooking container comprising a conductive layer to which is bonded A layer of material having high hysteresis loss  at microwave frequencies.  When subjected to microwave radiation the hysteresis loss material heats to its Curie point where its loss is substantially reduced while the dielectric loss is minimized by being effectively shielded by its proximity to the surface of the conductive layer.   The conductive layer may be a metal dish cover whose outer surface supports a plastic bonded ferrite and whose inner surface contacts a food body in a metal dish.  The Curie point region of the ferrite is lower than the degradation temperature of the plastic.  Overlapping the walls of the dish and cover forms a microwave seal to prevent microwave heating of the dish contents.
