91  DF  TRANSMITTER {22}
117.~ With electrical protection of transmitter circuit or operator


DEFINITION

Classification: 455/117

With electrical protection of transmitter circuit or operator:

(under subclass 91) Subject matter where the transmitter circuits or operators are protected from damage or injury such as from overload or malfunction of a component within the transmitter.

(1) Note. For classification in this subclass some detail of the transmitter must be claimed along with the protective means, claimed broadly or in detail, for protecting the operator or transmitter. Where the transmitter is claimed broadly (such as by name only) and the protective means is claimed in detail, classification is with the protective means.

(2) Note. The overload may be the result of a defective tube or other component within the transmitter or it may be the result of an external fault such as an antenna failure, lightning, or of transmission line arc-over.

(3) Note. Transmitters with temperature modifier or control means, such, for example, as cooling are in this subclass.

(4) Note. Transmitters with automatic condition responsive alarm are elsewhere in this class.

(5) Note. Operator protection is also included here.
