DEFINITION

Classification: 100/305

In press:

(under subclass 92) Apparatus wherein the means for changing the temperature or reducing the moisture content is so arranged that the treatment occurs in the means for subjecting the material to compressive force or during the compacting operation.

SEE OR SEARCH THIS CLASS, SUBCLASS:

38, for a method of pressing which includes subjecting the material to a change in temperature.

74, for a device for adding steam to the material in the means for subjecting the material to compressive force.

34, Drying and Gas or Vapor Contact With Solids,

70, for an apparatus for removing liquid from material in which there are two or more distinct means for removing the liquid by applying mechanical pressure to the solid material treated.

53, Package Making, 388, for a press for maintaining package flaps or seams under pressure for a sufficient time to (a) effect bonding or (b) set or dry the cover material; or having means to apply or remove heat from the flaps or seams while held in the device.

62, Refrigeration, for an apparatus for removing heat from a substance by a change of phase of the coolant (i.e., refrigerant) therein, especially

341, for a device including a shaping press for making a congealed product.

65, Glass Manufacturing,

319, for a glass press molding apparatus combined with apparatus heating or cooling means.

99, Foods and Beverages: Apparatus,

372+, for cooking apparatus having two imperforate movably connected heated plates or molds which confine and contact food material there between including a waffle iron or sandwich grill.

101, Printing,

3.1+, entitled "hot die" for an embossing or penetrating press in which there is means to heat a die performing a printing operation.

110, Furnaces,

223, for an incinerator having a press. 156, Adhesive Bonding and Miscellaneous Chemical Manufacture, for heated presses combined with other laminating features; see especially

583.1+, for a heated press unique to laminating.

162, Paper Making and Fiber Liberation, for a paper making operation that may involve a pressing step; especially

56, for a chemical process involving squeezing or compressing, subclasses 205+ for the subsequent pressure treatment of a formed web, subclasses 224+ for a process of treating an article by pressure, subclass 305 for the combination of a mold for forming a paper article combined with pressing means, and subclasses 358+ for a press combined with a felt.

219, Electric Heating,

600+, for inductive heating, subclasses 678+ for microwave heating, and subclasses 764+ for capacitive dielectric heating; subclasses 50+ and 149+ for metal heating by electricity, combined with shaping, where the shaping may be by means of a die; and subclasses 200+ for a miscellaneous electric heater.

249, Static Molds,

78, for a static mold having electrical heating means as part thereof and subclass 79 for a static mold with means within the mold body to confine a heat exchange medium.

366, Agitating,

79+, 156.1+, and 318+ for a screw-type conveyor or agitator and subclasses 144+ for heating and cooling means in an agitator.

425, Plastic Article or Earthenware Shaping or Treating: Apparatus, 200+, for a mixing or kneading device upstream of a plastic or article former, especially subclass 208 wherein the kneading device is in the form of a helix.

432, Heating, for the residual class for apparatus for or related method generating of heat and its application to materials, where the heat generating means is more than nominally recited.
