Title: Process for producing small spherical particles
Filed: 1933-02-22
Abstract: <PICT:0415456/III/1> Particles of substantially spherical shape are obtained by passing irregularly shaped particles through a zone heated to such a temperature that the particles melt superficially. The process is applicable to the treatment of metals, oxides, ceramic materials, silicates, glass, or mixtures thereof, and to operations including coating.  The particles may fall freely through a heated zone or may be floated in a gas current of variable density or composition, or mixtures of metal and ceramic material, silicates, &c., may be treated to obtain coated particles, which may in some cases be treated a second time to melt only the coating material.  In the apparatus shown, the material to be treated is passed from a hopper g through one or more oscillating screens b to a pipe c heated by an electric resistance d, or by induction, and cooled at i<1>, i<2>. A gas such as hydrogen is passed through the pipe and the treated particles are collected in a dish l which may be in the hydrogen atmosphere or may be outside so that the surface of the particles is oxidized; or the particles may drop into a liquid bath.

An air heater comprises an air duct 19 in which is arranged a heat exchanger supplied with hot gases from a combustion chamber 20 fired by a burner 22. The air heater is intended for connection to an air supply duct 10 through which air is forced by a fan 13 driven by an internal-combustion engine 11, the air being thus preheated by compression in the fan and by contact with the I.C. engine before receiving further heat as it passes over the flue tubes 28a, 28b of the heat exchanger. The combustion air flow is aided by a fan 24 driven by an electric motor 23 or by the I.C. engine 11. The burner gas flow through the tubes 28a, 28b may be in parallel as shown or in series (Fig. 3). In further forms (Figs. 4 and 5), the I.C. engine (11) and fan (13) are downstream of the heat exchanger. The fan induces an air flow through the air duct (19) which is connected to the fan duct (10) by a flexible connection (32, Fig. 4) or two connections (41, 42, Fig. 5). The induced air flow enters the duct 10 in a direction inclined to its axis. The heated air may be used for the drying of crops, ships or buildings. Mechanical, electrical or electronic equipment may be provided for cutting off the fuel supply to the burner 22 if the flame is extinguished. The flame is ignited by an electrical or flame igniter 25. Fuel supply to the burner and hence the heated air temperature is controlled manually or by a thermostat in the air passage 19.
