SECTION H — ELECTRICITY
 H05
ELECTRIC TECHNIQUES NOT OTHERWISE PROVIDED FOR
 H05B
ELECTRIC HEATING; ELECTRIC LIGHTING NOT OTHERWISE PROVIDED FOR (apparatus for special application, see the relevant class or sub-class, e.g. A47J, F21V, F24D, F24H, F27B)

 H05C
ELECTRIC CIRCUITS OR APPARATUS SPECIALLY DESIGNED FOR USE IN EQUIPMENT FOR KILLING, STUNNING, OR GUIDING LIVING BEINGS

 H05F
STATIC ELECTRICITY; NATURALLY-OCCURRING ELECTRICITY (electrostatic machines H02N; uses of electricity in performing operations, e.g. precipitation, see the relevant sub-classes for the operations)
 H05F

Note(s)

This sub-class deals with methods or arrangements for preventing the formation of electrostatic charges on bodies or for carrying-off these charges after their formation. Specific applications of these methods or arrangements, e.g. during the manufacture of artificial fibres or films, are dealt with in the relevant sub-classes.


 H05G
X-RAY TECHNIQUE (X-ray therapy A61N; testing by X-rays G01N; apparatus for X-ray photography G03B; X-ray tubes H01J 35/00)

 H05H
PLASMA TECHNIQUE (thermonuclear reactors G21B; magnetohydrodynamic generators H02N 4/02); PRODUCTION OF ACCELERATED ELECTRICALLY-CHARGED PARTICLES OR OF NEUTRONS (obtaining neutrons from radioactive sources, e.g. in nuclear reactors G21; details not specially adapted to particle accelerators H01J)
 H05H

Note(s)

This sub-class deals with (a) devices not covered by H01J and in which electrons or ion beams are accelerated to high energies by electric or magnetic fields and (b) devices in which electrons or ion beams are accelerated to high energies by repeated or continuous application of relatively small voltages.


 H05K
PRINTED CIRCUITS; CASINGS OR CONSTRUCTIONAL DETAILS OF ELECTRIC APPARATUS; MANUFACTURE OF ASSEMBLAGES OF ELECTRICAL COMPONENTS (casings for, or constructional details of, particular types of apparatus, see the relevant sub-classes; processes involving only a single technical art, e.g. heating, spraying, for which provision exists elsewhere, see the relevant class; details of instruments or comparable details of other apparatus not otherwise provided for G12B)
 H05K

Note(s)

  1. "Printed circuits" are understood as covering all kinds of mechanical constructions of circuits that consist of an insulating base or support carrying the conductor and are combined structurally with the conductor throughout their length, especially in a two-dimensional plane, the conductors of which are secured to the base in a non-dismountable manner, and also as covering the processes or apparatus for manufacturing such constructions, e.g. forming the circuit by mechanical or chemical treatment of a conductive foil, paste, or film on an insulating support.
  2. This sub-class is understood as covering combinations of a radio or television receiver with apparatus having a different main function.
  3. This sub-class is also understood as covering printed circuits structurally associated with non-printed electric components.
