Patents Early index

There is a considerable patent art concerning preparation of transparent mixtures of water with low molecular weight silicone oils using polymeric silicone surfactants. Some representative early references are Keil [47], Gee [48, 49], Gum [50] and Terae [51]. These compositions are called micro emulsions in the patents in the sense of being transparent mixtures of water, surfactant and oil - but note that they are transparent because of small particle size or because of index of refraction matching. [Pg.195]

In common with chemical information published in many other countries, material of interest printed in French chemical books, journals, and patents has, in the past, been difficult of access, primarily because of the lack of organization and centralized documentation on one hand, and as a result of haphazard indexing on the other. This applies especially to the publications printed during the nineteenth century and the early part of the twentieth century. [Pg.487]

Web of Science and around 1000 zeolite related patents per year can be found under the same Topic search in the Derwent Innovation Index . The number of new Zeolite Framework Type Codes (FTCs, see below) also grows fast, with an average of over 7 FTCs per year for the last 12 years. This chapter tries to cover a vast portion of zeolite science at an intermediate level, with a focus on and more in-depth coverage of zeolite synthesis. The chapter is organised in, perhaps, a less usual way, since the general sections on structural and compositional chemistry and applications go before the more specific sections on synthesis. We think the early sections will show that the vast richness of current zeolite science and applications heavily rehes on an enormous synthetic effort that we will try to summarise and rationalise in the later sections. [Pg.267]
