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. Fulltext... Hierarchy... Expanded...A47J, Fulltext... Hierarchy... Expanded...F21V, Fulltext... Hierarchy... Expanded...F24D, Fulltext... Hierarchy... Expanded...F24H, F 27 C)

|  | 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 Fulltext... Hierarchy... Expanded...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 Fulltext... Hierarchy... Expanded...A61N; testing by X-rays Fulltext... Hierarchy... Expanded...G01N; apparatus for X-ray photography Fulltext... Hierarchy... Expanded...G03B; X-ray tubes Fulltext... Hierarchy... Expanded...H01J 35/00)

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

|  | H05H |
Note(s) This sub-class deals with (a) devices not covered by Fulltext... Hierarchy... Expanded...H01J and in which electrons and/or ion beams are accelerated to high energies by electric and/or magnetic fields and (b) devices in which electrons and/or ion beams are accelerated to high energies by repeated or continuous application of relatively small voltages.

PRINTED CIRCUITS; CASINGS OR CONSTRUCTIONAL DETAILS OF ELECTRIC APPARATUS; MANUFACTURE OF ASSEMBLAGES OF ELECTRICAL COMPONENTS (casings for, or constructional details of, 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)

|  | H05K |
Note(s) "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. This sub-class is understood as covering combinations of a radio or television receiver with apparatus having a different main function.
