The machinery of this heading is distinguished fiom the parts of machinery, etc., that fa1 to be classified in accordance with the general provisions concerning parts, by the fact that it has individual functions. For this purpose the following are to be regarded as having " individual functions " : (A) Mechanical devices, with or without motors or other driving force, whose function can be performed distinctly from and Independently of any other machine or appliance. Example :Air humidification and dehumidification are individual functions because they can be performed by appliances operating independently of any other machine or appliance. A separately presented air dehumidifier, eve? if desi ed to be mounted on an ozone generator falls, therefore, to be class~fiedin 8 s heading as having an individual function. (B) Mechanical devices which cannot perform their h c t i o n unless they are mounted on another machine or appliance, or are incorporated in a more complex entity, provided that this function : (i) is distinct from that which is performed by the machine or appliance whereon they are to be mounted, or by the entity wherein they are to be incorporated, and (ii) does not play an integral and inseparable part in the operation of such machine, appliance or entity. Example :A chain cutter is a device which is mounted on an industrial sewing machine and which automatically cuts the thread so that the machine can run without interruption. This device performs an individual function because it plays no art in the " sewing fimction of the machine; as there is no other more specific " Reading, the chain cutter falls to be classified here. On the other hand, the function of a carburettor for an internal combustion engine is distinct from that of the engine but it 1s not "individual function " as defined above because the operation of the carburettor is inseparable from that of the engine. Separate1 presented carburettors are therefore to be classified as parts of engines in heading 4.09. i Similarly, mechanical or hydraulic shock absorbers form an integral part of the machine or ap liance in which the are to be incorporated. Separate1 presented shock absorbers therePore fall to be classi ed an parts of the machines or d i a n c e s on which they are to be mounted. (Shock absorbers for vehicles or aircraft fall m Section XVII).

S (7) Industrial robots for multiple uses. Industrial robots are automatic machines which can be programmed to carry out repeatedly a cycle of movements. By the use of sensors, industrial robots are able to acquire information about the field in which they operate and to analyse the information thus obtained to be able to adapt their pattern of activity to variations in their field of operation. Industrial robots may consist of an articulated arm, mounted on a base in a horizontal or at its extremity a mobile holder for the toolholder also consist of a rectilinear structure often moving part of the operating mechanism often moving on a horizontal axis (horizontal robots).
