MATERIALS FOR REFRACTORIES AND CERAMICS. A STUDY OF PATENTS AND PATENT APPLICATIONS
The present survey is the result of a comprehensive study of patents and patent applications submitted in France, the Federal Republic of Germany, the United Kingdom and Europe (Munich), published since 1976 and comprising more than 750 publications, classified in accordance with the International Patent Classification, classes C 01 B; sub-classes 21, 33, 35; C 01 G, sub-class 25; C 04 B, sub-class 35. The major part of the patents was granted to applicants from the United Kingdom, the Federal Republic of Germany, France, the United States of America and Japan. Although the I.P.C. of basic refractories and ceramics produced therefrom is most useful in assessing validity and in supporting "prior art" searches, it does not satisfy the requirements of scientists and technicians who work in this field and who are also interested in the composition of such materials and the methods for producing them. As regards Part III, relating to finished products, it was decided to follow a classification based on specific parts of machines and installations where ceramics are most commonly applied. It should be observed that ceramic machine parts and other ceramic compositions are widely spread over the I.P.C. system, comprising more than 10,000 documents published since 1975. Therefore, only applications of ceramics which belong to the C 04 35 sub-class have been discussed, but in the abstracts reference has also been made as far as possible to the ceramic composition used in producing the respective parts. Finally Part IV deals with apparatus for producing refractories, intermediate and finished ceramic products, again in connection with the literature classified in the C 04 B 35 sub-class.
