This class is the generic class for primary, secondary, and
thermal batteries. It includes the structure of the generator or
battery itself, the elements thereof, the methods of preparation,
operation, and details, and accessories not provided for in other
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Pyromagnetic generators are found in Class 310, Electrical
Generator or Motor Structure, subclass 306.
The application and use of the battery in combination with
other devices should be searched for in the appropriate art classes.

quantity or quality of invisible radiation and subclasses 200+ for
visible radiation pyrometers including circuit structure for the
Electrical Generator or Motor Structure,
subclass 306 for thermal or pyromagnetic generating devices
wherein there is additional control means for the generated power
current. Also, subclass 306 for thermionic device, per se, or in
combination with a thermoelectric device.
This subclass is indented under subclass 200. Apparatus wherein nuclear energy other than that resulting
from an induced nuclear reaction is used as a heat source for the
generator or comprising a thermoelectric device designed to be employed
as an ancillary unit in a nuclear reactor system.
Note. Nuclear energy of this subclass type may be that which
results from radioactive decay.
subclasses 3.1+ for thermoelectric cooling devices wherein the
device is more than a battery-like assemblage and contains some
structure peculiar to refrigeration by Peltier effect, e.g., a current source
This subclass is indented under subclass 200. Apparatus wherein a thermoelectric composition is claimed.
Note. To be placed herein rather than in a composition class,
a thermoelectric device defined by composition only must claim at
least two elements of the thermoelectric device, e.g., two junction elements
of a couple.
This subclass is indented under the class definition. Device which generates an electric potential upon exposure
to light, by the direct conversion of the light to electrical energy,
Note. Similar structures may be disclosed as having other
functions, e.g., rectifying, photoconductive, etc., and some of
these photoelectric devices may be disclosed as having several functions.
A patent which discloses or claims only a photovoltaic use will
be placed here. A patent which claims other uses or which is claimed
generically will be placed in another pertinent class, e.g., Class
250, Radiant Energy, or Class 257, Active Solid-State Devices (e.g.,
Transistors, Solid-State Diodes).
This subclass is indented under subclass 243. A photoelectric cell combined with (a) at least one other
photoelectric cell, or (b) a different electric generating means
(e.g., galvanic), or (c) distinct perfecting means for the photocell (e.g.,
This subclass is indented under subclass 244. Device which includes means to associate various parts or
elements in a first compact arrangement for storage and/or
transport and also in a second operative arrangement for accepting
radiation, said device also utilizing materials and structures designed
to decrease the mass or gravitational attraction.
