first category of restrictions and has a eleerly exclusive effect. The second type of restriction does not prevent the future action of the firm but limits Its capacity for modifying the techniques during the period when the licence Is being used. The restriction Is cal led a restriction on possible movements: "During manufacture, (the licensee) agrees to follow the drawings submitted by tht ll~•n,cr, aiHI will not be allowed to deviate from them without fils consent"<2~)J also: "The concesslonalr• It eo~mltted not to modify or Improve the . said (product) nor the ~achlnes using It, without a written authorisation for thlt procedure from (the llcensor)(24). It could be ••14 that this type of restriction Is laid down by some firMs t~ stop their national counterparts moving away from the original designs as they use the technology and start a process by whiCh they wll I eliminate the contractual relationshiP (25). But such restrictions are not generally used. since most ~ontracts contain clauses which have a specific, distinct aim: to appropriate possible Innovations which may develop during the use 6f the I lcence (not to restrict them). So we come to the third type of restriction: that wh.lch applies to new techniques developed locally. 23. Contract for the manufacture of paints and plastic coverings 24. Text from a contract referring to· the manufacture of equipment 25. Another way of limiting local creative effort Is by restricting Information e.g. "the firm granting the license Is not obi lged to divulge to the licensee plans· of the parts or sub assemblies that he (the licensor) wIll hI mse(f assemble or buy within his own country". (Agreement for the manufacture of parts for concrete mixers). Another restriction limits actual manufacture:" the (licensee) Is committed to using the I !censor's drawings or other documents 
**Analysis**
The text appears to be discussing various types of restrictions and limitations imposed on a firm that has obtained a license to manufacture a product. The restrictions are related to the firm's ability to modify techniques, use technology, and access information. These limitations seem to be aimed at protecting the intellectual property and commercial interests of the licensor. Given the context, it is likely that the category is related to industry or technology.
