Abstract: A chamber such as a curing oven or drier is inerted during the curing of solvent borne resin coatings with the solvent vapor formed therein being withdrawn together with inert gas at a substantially constant flow rate. The withdrawn gas stream is supplied to a condensation unit to enable recovery of solvent and the noncondensed gas discharged from the condensation unit is returned to the oven at a flow rate which may be varied so as to maintain a material balance with respect to the oven atmosphere. Appropriate adjustments are made in response to changes occurring in the oven solvent vapor and/or oxygen concentration without disturbing the material balance mentioned above while the oven atmosphere is withdrawn at a substantially constant flow rate. A plurality of ovens may be connected to a single condensation unit and upon detecting undesired conditions such as excessive oxygen levels in one oven, the same may be separately isolated from the condensation unit.

Abstract: An energy efficient method of drying and curing insulation on wire, especially magnet wire, is disclosed. Heated gases are used separately to dry and cure a curable insulating coating such as a phenolic resin. Gases exhausted from the drying and curing operations and containing volatile combustible materials evolved from the drying and curing of the coating, is passed to a heat exchanger where they pick up heat from the exhaust gases of a fume burner. The hot gases are then passed to the fume burner where the combustible materials are burned to add heat of combustion to the gas stream, which is then cycled back as the fume burner exhaust through the heat exchanger, mixed with air, and passed to the drying section of the wire oven. This recapture of the heat from the combustion provides the heat needed for drying of the coating, thus maximizing the energy efficiency of the process. Apparatus to perform the process is also disclosed.

Continuous switching takes place between the gas streams and the chambers, so that each of the chambers is periodically traversed, at first, successively by all of the partial streams of the drying medium in order of increasing moisture contents, and subsequently, by the gaseous medium to regenerate the adsorbent. Following each switching, at least one of the chambers of each group is assigned to the next following group in the cycle.

Abstract: A process for dressing a single or multiple-grooved worm or threaded workpiece by a single or multiple-grooved worm or threaded dressing tool includes the turning of the workpiece and tool with the dressing tool in a comb-type contact with the workpiece. By using an additional axial relative movement between the dressing tool and the workpiece, determined by the radial positioning and return movements, the contact points are displaced such that the desired grinding profile is produced on the workpiece. Since the entire surface area of the instantaneous contact points is significantly smaller than the entire profile area of the workpiece, the cutting forces which occur are relatively small, so that high dressing speeds can be obtained. It is also possible to make various flank corrections on the workpiece. The apparatus for carrying out the process is also disclosed.
