literature Fibre optics technology and markets A new study by market research specialists Frost ~ Sullivan Inc of New York, USA (report No 549). The already crowded field will be characterized by poor return on investments', the 211 page report study warns. Not that the market will stagnate. On the contrary, over the next 10 years, fibre optic shipments will increase more than five-fold-from $11 million in 1978 to $60 million by 1987. The total, however, is paltry when compared to either market projections touted by others or the market values on alternative technologies that proponents of fibre optics hope to displace. Says the study : 'We dispute the widely heralded forecasts of explosive growth for fibre optics markets during the coming decade'. Such a cautious overall forecast shows up, of course, in the market projections by specific product categories though the percentage gains turn out to be very significant, as follows :
instrumentation, control, fault finding and general practice, in all uses of freeze drying in research, development, medicine and industry, and there is a comprehensive index and three pages of bibliography and suggested reading. The new section will be of really practical help to all involved in freeze drying, from operators of equipment to designers of complete production facilities. It covers every aspect of industrial freeze drying, examining for example, the principal production techniques, types of equipment and plant available and their pros and cons in different circumstances, and suitable techniques in, for example, material loading and general handling. Of particular value is a is a comprehensive section, containing tables, examples, and typical freeze drying curves reproduced in full colour, which gives guidance on determining and optimizing cycle times and, hence, productivity for a wide range of different produc~ groups and sizes of plant, Edwards High Vacuum, Manor Royal, Crawley, West Sussex RH10 2LW, UK

Breaking out projected 1987 sales, the military market will be $20 million by then ; telephony, $22 million ; and telecommunications $10 million. Computers and terminals, industrial applications, and so-called wired home will each be at a $2 million level as well. Technical problems, in particular, hold back commercial implementation of fibre optic systems. Besides technical hurdles, a 'complicated and difficult struggle' in 'largely unchartered waters" relates to business, public and political aspects as well. No supplier of optical fibres and cable, for example, yet has a hold on the market through significant performance or pricing advantage. Nor does any supplier turn out the optical fibre links in truly large-scale production. As a result, 'current pricing does not reflect the eventual volume-based prices that will ultimately prevail', the study says. Other fibre optics markets, besides that used to generate and transmit data and voice information, also exist, the study points out. These include instrumentation, illumination, and image transmission. The automobile market will open up for example, when automobile electronic systems include significant digital data processing. In addition, the study points to 'off beat' markets. One is for specialty software tailored to fibre optics-based telecommunications systems. Another is for manufacturing equipment that now consists mainly of proprietary in-house machinery and procedures that employ high-priced labour--technicians and engineers. Production equipment that uses lower priced blue-collar, hourly employees is needed instead the study says. Frost ~ Sullivan Inc, 106 Fulton Street, New York, NY 10038, USA
RIBER quadrupole mass spectrometers The increasing demand on quadrupole performances has led to an increasing size of quadrupoles and as a corollary to increasing requirements on power supplies. The large size RIBER quadrupole is already well known and used all over the world by more than a hundred laboratories. It is at present with the SQ 156 large quadrupoie assembly and with the AQ 156 high efficiency power supply to go up to mass 1000 with high voltage and high frequency. The same power is also used for the 1-300 and 2-600 mass ranges so that optimum results in the mass range of interest is achieved. Furthermore, development on the ion introduction optics has also dramatically increased the dynamic range of thd Q156 (up to 10 l° is now possible). On the other hand, for ultra high vacuum residual gas analysis, an uhv ion source has been developed and achieved, so that you really analyse what is in your uhv. Also the quickly developing molecular beam analysis requires now highly stable and sensitive quadrupoles for the control of processing and is using the Q156 for this purpose. Technical brochures are No 267E describing in outline the structure and performance of the SQ156, the AQ156 and a leaflet on the LAS2000 surface analysis system, where I_AS implies an analysis for LEED-MICROSONDE AUGER-SIMS.

Edwards Freeze Drying Handbook The second edition of the Edwards Freeze Drying Handbook, which now runs to 132 pages, contains a new 30 page section on industrial freeze drying. The large (A4) page format has been retained and the book makes copious usa of illustrations, avoiding unnecessary formulae and technical language. The book's 26 chapters cover all necessary aspects of theory, equipment,
