Book reviews
polyurethane. It presents the details of synthesis, and explains the chemical and physico-chemical subtleties of their fabrication. It also attempts to link data and information concerning the chemistry and technology of oligo-polyols for polyurethanes
Two specialized books of potential interest to those working in the individual areas concerned have been published recently.
Chemistry and technology of polyols for polyurethanes This is a new handbook from Rapra Technology. It considers the raw materials used to build the polyurethane polymeric architecture and covers the chemistry and technology of oligo-polyol fabrication, characteristics of the various families, and the effects of the structure on the properties of the resulting 6

Dry gas seals handbook This book offers a comprehensive introduction to dry gas seals, selection, installation and operation.
Aerospace supplier purchases majority share of seal company Heico of Hollywood, Florida has taken a 51% interest in Seal Dynamics LLC for an undisclosed amount of cash. Seal Dynamics chief David J. Susser will continue to own the balance of the company. Heico says it does not expect to see employee turnover at Seal. Heico’s aerospace unit will broaden its product portfolio of aircraft parts, as well as other industrial products, with the deal. Heico Aerospace Holdings Corp is owned 20% by Lufthansa
Technik AG, and is the world’s largest independent designer, manufacturer and distributor of FAAapproved jet engine and aircraft component replacement parts. The acquisition of SDI is seen as allowing Heico to broaden its product portfolio of aircraft parts, as well as other industrial products.

One-off seals available in a hurry In the UK, Wyko Industrial Services has teamed up with Economos to provide CNC machined seals. The service will be available from Wyko’s Halesowen Seal Centre to serve end-users, the company’s repair workshops and the national branch network. Seals from 5 mm to 4000
mm diameter can be machined in a range of 15 materials. Contact: Wyko Industrial Services, Amber Way, Halesowen, West Midlands B62 8WG, UK. Tel: +44 121 508 6341, Fax: +1 121 508 6255. Email: [email protected], Web: www.wyko.co.uk
Financial partner acquires seal company UTEX Industries Inc has been acquired by Grey Mountain Partners. This acquisition is expected to provide for further growth of the company, while retaining the present level of service. It will continue to operate as UTEX Industries Inc, while seeking new
markets, innovations and seal design concepts.
Author John S. Stahley is an engineer responsible for compressor commissioning with Dresser-Rand, and he has first-hand experience of these seals and their requirements. The book does not assume prior knowledge, and has a comprehensive glossary, so the reader does not immediately get lost in jargon. It covers the history, basic design and seal configurations in turn. The relative merits of different seal designs and configurations are discussed. The various venting, seal and buffer gas supply, and safety systems are discussed step by step to make them readily understandable. The problem of seal contamination, which the author considers to be the major factor in seal
reliability, is covered in some depth. Finally, a series of field experience examples illustrates how problems have arisen and been solved. As someone well aware of gas seals but not with a lot of direct personal involvement, I found this a very useful and informative book. A few illustrations are not of very good quality, but these can usually be referenced to a seal manufacturer’s catalog or website for a better version. This is a very worthwhile little book.
