.~ Having control means for heating or cooling means
DEFINITION
Classification: 60/515
(under subclass 508) Apparatus of a working chamber having means exterior of working chamber heat exchange therebetween and means to control the rate of BTU transfer to the chamber.
(1) Note. The means disposed exteriorly the working chamber may include a jacket spaced from the working chamber or a coil which may be an electrical resistance element or a pipe having fluid flow therethrough for the purposes or heating or cooling.
(2) Note. The control means includes a valve which controls the flow of fluid through the jacket or coil or an electrical control for the resistance.
(3) Note. A working chamber disposed within the furnace chamber is properly classified under 515 where a control for the furnace is disclosed.

92, Expansible Chamber Devices,
144, for an expansible chamber type motor in which the working chamber is jacketed for heat transfer therebetween but where there is no control valve for either the motor or the jacket fluid. 123, Internal-Combustion Engines,
41, 72+ and 195 for a jacketed cylinder or end closure therefor for receiving circulating heat exchange liquid to
cool the operating parts of an internal combustion engine. A specific disclosure that a jacketed cylinder or end closure therefor is to form a part of an internal combustion engine is sufficient for classification in Class 123.
165, Heat Exchange, appropriate subclasses for a heat exchange modifying space or jacket of general utility. Class 165 takes a nominally claimed cylinder or working chamber forming member of an expansible chamber device, where the claim is otherwise directed to a surrounding space or jacket designed to modify the heat exchange properties of the cylinder or member.
220, Receptacles,
592.01+, for a receptacle having means to maintain its contents above or below ambient temperature.
