| 摘要 | An improved apparatus for generating superheated vapors of vaporizable organic liquids having a novel superheating section capable of delivering a wide swath of superheated vapors. The new section is substantially a loop of electrical resistance tubing connected to the vapor generating section of a mobile or handheld electrical resistance tube heater. The loop is hollow through about two-thirds of its length, the remainder, the return to the electrical circuit, being solid. The tubular portion of the superheater has a plurality of perforations in a substantially straight section, which section is surrounded by a slotted housing for directing the vapors entering the housing from the perforated tube. | ||||||
| 权利要求 | 1. An apparatus for generating superheated vapors from liquid compositions based on a poorly conductive organic liquid which comprises: a. a tubular electrical resistance heater coil having an inlet end and an outlet end, b. a shield around said heater coil, c. a handle for said shield, d. a superheater element of electrical resistance material, electrically and fluidly connected to the outlet end of said coil, said superheater element being tubular through a major portion of its length and provided with a straight section which is at right angles to the axis of the heater coil and which straight section is perforated along its length on the side nearest the shield, said perforated tubular section being surrounded by a housing having a longitudinal slot in indirect communication about 180* from said perforations, said tubular portion of said superheater terminating in a solid electrical conductor returning to said shield for completion of the electrical circuit and for positioning said superheater element with respect to said shield. |
