This heading covers all electrical appliances and apparatus not falling in any other heading of this Chapter nor covered more specifically by a heading of any other Chapter of the Nomenclature nor excluded by the operation of a Legal Note to Section XVI or to this Chapter. The principal electrical goods covered more specifically by other Chapters are electrical machinery of CHAPTER84 and certain instruments and apparatus of CHAPTER90. The electrical appliances and apparatus of this heading must have individual functions. The introductory provisions of Explanatory Note to heading 84.79 concerning machines and mechanical appliances having individual functions apply mutatis mutandis to the appliances and apparatus of this heading. Most of the appliances of this heading consist of an assembly of electrical goods or parts (valves transformers capacitors chokes resistors etc.) operating wholly electrically. However the heading also includes electrical goods incorporating mechanical features provided that such features are subsidiary to the electrical function of the machine or appliance. The heading includes inter alia :
(1) Particle accelerators. These are devices for imparting high kinetic energy to charged particles (electrons protons etc.). Particle accelerators are used mainly in nuclear research but they also serve
in the production of radioactive materials in medical or industrial radiography for the sterilisation of certain products etc. Particle accelerators usually consist of large installations (which may weigh several thousands of tons). They comprise a particle source an acceleration chamber and devices for producing high frequency voltage variations of the flux or radio-frequencies which are used to accelerate the particles. They may contain one or more targets. Acceleration focalisation and deflection of the particles are achieved by electrostatic or electro-magnetic devices which are fed by high voltage or high frequency generators. Accelerator and generators are often enclosed in an anti- radiation screen. The particle accelerators covered by this heading include Van de Graaff accelerators Cockcroft and Walton accelerators linear accelerators cyclotrons betatrons synchrocyclotrons synchrotrons etc. Betatrons and other particle accelerators specially adapted for the production of X-rays including those capable of producing either beta-rays or gamma-rays as required fall in heading 90.22.
(2) Signal generators. These are apparatus for the production of electrical signals of known wave-form and magnitude at an assignable frequency (high or low frequency for example). These include inter alia : impulse generators pattern generators wobbulators (sweep generators). (3) Mine detectors based on the change of magnetic flux produced in the apparatus when brought near to a metal object. Similar detectors are used for example for detecting foreign metallic bodies in casks of tobacco food products timber etc. and for locating buried pipes. (4) Mixing units used in sound recording for combining the output from two or more microphones; they are sometimes combined with an amplifier. But mixing units specialised for cinematography are excluded (heading 90.10).
(5) Noise reduction units for use with sound recording apparatus. (6) Defrosters and demisters with electric resistors for aircraft ships trains or other vehicles (except cycles or motor vehicles - heading 85.12).
(7) Synchronisers for use when several generators are feeding into a common circuit.
(8) Electrical mine detonators consisting of a hand generator (dynamo) and a capacitor.
(9) High or intermediate frequency amplifiers (including measurement amplifiers and aerial amplifiers).
(10) Machines and apparatus for electroplating electrolysis or electrophoresis (other than electrophoresis instruments of heading 90.27).
(11) Ultra-violet irradiation equipment for general industrial uses.
(12) Ozone generating and diffusing apparatus electric designed for non- therapeutic purposes (e.g. for industrial uses for the ozonisation of premises).
(13) Electronic musical modules for incorporation in a wide variety of utilitarian or other goods e.g. wrist watches cups and greeting cards. These modules usually consist of an electronic integrated circuit a resistor a loudspeaker and a mercury cell. They contain fixed musical programmes.
(14) Proximity cards or tags and electronic proximity cards/tags which may or may not have a magnetic stripe. Proximity cards/tags usually consist of an integrated circuit with a read only memory which is attached to a printed antenna. The card/tag operates by creating a field interference (the nature of which is determined by a code contained in the read only memory) at the antenna in order to affect a signal transmitted from and reflected back to the reader. This type of card/tag does not transmit data.
Electrostatic proximity (ESP) cards/tags usually consist of a coil which is activated by a signal from a reader and produces a voltage to power a microcircuit a code generator which on receiving a signal from the coil generates data and a signal transmission antenna.
This heading excludes cards commonly known as " smart " cards which have embedded in them an electronic integrated circuit (e.g. microprocessor) in the form of a chip and which may or may not have a agnetic stripe (heading 85.42).
(15) Ion implanters for doping semiconductor materials.
(16) Electric fence energisers.
