An apparatus for tempering a bent glass sheet is disclosed. The apparatus comprises means for conveying the sheet through the apparatus and a pair of blastheads for quenching the sheet with quench gas. Each blasthead comprises a plurality of spaced elongate plenums for supplying quench gas to an array of quench nozzles, the nozzles being mutually inclined to provide diverging jets of quench gas. The plenums extend transversely to the direction of conveyance of the sheet, and the array of nozzles is curved in at least one direction. The array may comprise rows of nozzles extending along lines which are curved in the direction of elongation of the plenums; preferably the curvature of the rows matches the average local curvature of the bent glass sheet in the corresponding direction. Also disclosed is a production line incorporating the apparatus.

The present invention relates to a process and a device for applying tensile forces, with no contact with solid walls, to glass sheets, in particular at high temperatures, wherein a gas or vapor is blown between the glass sheet and a wall closely approached, and parallel, to said glass sheet. Between the glass sheet and said wall a gas cushion is established, in that the sections through which the gas flows inside the air gap between the glass sheet and the wall increase on the average in the direction of streaming of the gas, so as to allow the gas speed to decrease, and a recovery in gas pressure to consequently take place. Several forms of practical embodiment of the device are disclosed.

A fluidized bed filtering and heat exchange apparatus particularly for treating gaseous discharges from internal combustion engines and industrial plants comprises a vertical-axis elongated casing (10) having a filler of inert, particulate material therein, a gas feed manifold (36) provided with discharge nozzles arranged to direct gas downwardly into said casing (10) to maintain said filler in a fluidized state, and a cyclone (58) communicating with the upper part of said casing (10) to receive said gas therefrom and to separate agglomerated particles from said gas. Heat-exchange means are provided for cooling the fluidized filler including a plurality of tubes (46) for carrying a heat-exchange fluid therethrough.

Fluidized bed filtering and/or heat exchange apparatus particularly for

The invention provides variation in the delivery of oxygen to converters for refining metal. Thus, oxygen blowing into such converters in unstationary manners, i.e., varying degrees of pressure and/or flow rate, is performed by means of partialization of the nozzles of the lance heads, or by means of decreases in the penetration capacities of the oxygen jets throughout the blowing process or during a part only of the same resulting in greatly improved reaction rates.

Method and device for blowing oxygen in metal refining converters in

The object of the present invention consists of improved nozzles for the lance heads for blowing oxygen from above, in the refining processes.
