Abstract

296,525. Hammond, C. F., and Shackleton, W. April 13, 1927, Heating liquids.-Liquid is heated and circulated by means of a submerged burner, in connection with. the treatment of textiles. In Fig. 1, the burner f acts on the liquid in a sump d, aerating it and causing it to rise, and re-enter the bath under the deflecting, part h of a throat k through which the materials are introduced, the liquid being drawn through holes 7 down the duct c. Gases escape by the channel o to an outlet 5. The lid m may be raised by sliding a, weight 3, Fig. 5, along an arm 2. The sump d may be centrally situated. The supply of fuel and air to the burner may be controlled by a thermostat or by the pressure in the bath. In Fig. 7, the burner 11 in the sump 10 causes the liquid to rise into an upper tank 13 where gases are released, whence the liquid returns by passages 15, 16 to the vat. Where a high temperature is necessary, the vat may be jacketed and a liquid of high boiling-point circulated through the jacket by a submersible burner. Specification 265,254 is referred to.
