DEFINITION

Classification: 100/92

(under subclass 70) Apparatus in which the means to subject

the material compacted to additional treatment includes means for changing the temperature or reducing the moisture content of the material compacted.

(1) Note. Included here are patents to a device otherwise meeting the definitions of Class 269, Work Holders, but combined with heating, cooling or drying means. See the class definition of Class 269, section VIII for the line with this class (100).

SEE OR SEARCH THIS CLASS, SUBCLASS:

73+, for adding steam or other heated fluid to the material being pressed.

SEE OR SEARCH CLASS

34, Drying and Gas or Vapor Contact With Solids, 70, for apparatus for removing liquid from material in which there are two or more distinct means for removing the liquid and at least one of the means causes liquid removal by applying mechanical pressure to the solid material treated, and subclass 145, for apparatus in which the material to be treated is held between two opposed members which are movable or expansible toward one another to press or retain the material, and away from each other to release the material and there is means to pass a gas or vapor into contact with the material treated.

37, Excavating,

226, for apparatus for excavating and compacting snow in which the compressor for the snow is provided with a heater.

38, Textiles: Ironing or Smoothing,

74, for flat irons.

68, Textiles: Fluid Treating Apparatus,

20, for machines combined with means to facilitate drying of the textiles by means of the passage of a gaseous medium through the textiles or by withdrawing vapor from the textiles.

72, Metal Deforming, appropriate subclasses, for a combined machine for plastically shaping metal and otherwise treating it, e.g., handling, cleaning or deoxidizing it, as provided for in the class. Heating or cooling means for merely taking the work to or from a proper working temperature are included whether specifically set forth in the subclass titles or not.

144, Woodworking,

254, for a wood bending machine which includes a heating

device for drying the wood in its bent form.

165, Heat Exchange, 168+, for a heat exchange platen, per se.

219, Electric Heating,

50+, for metal heating (e.g., resistance heating, etc.), especially subclasses 149+ for forging or shaping of a work piece, subclasses 443.1+ for an exposed horizontal planar support surface for material to be heated (e.g., hot plate, etc.), subclasses 600+ for inductive heating, subclasses 678+ for microwave heating, or subclasses 764+ for capacitive dielectric heating.

241, Solid Material Comminution or Disintegration,

65+, for comminutors with means to modify the temperature of the material.

266, Metallurgical Apparatus,

102+, and 160+, for apparatus which coils and heat-treats metal.

269, Work Holders, appropriate subclasses, Class 269 is the residual locus for patents to a device for clamping, supporting and/or holding an article (or articles) in position to be operated on or treated. See notes thereunder for other related loci.

422, Chemical Apparatus and Process Disinfecting, Deodorizing, Preserving, or Sterilizing,

285+, for melt separators.

425, Plastic Article or Earthenware Shaping or Treating: Apparatus, appropriate subclasses for shaping or reshaping apparatus for nonmetals including heating or cooling means for in situ treatment, especially

383+, for a vulcanizing means including a preform support, subclass 407, for a press couple shaping apparatus including heating and cooling means; and subclass 446 for means treating shaped work in or on a work confining surface; see the search notes thereunder.
