The Technician Education Council was established in 1973, but only now are its aims being understood and appreciated. This paper reviews the general patterns set by the Council and the particular programmes available for those seeking Associate-Membership of the Institution. It discusses entry requirements, activities of the technician, recent developments, and indicates the degree of flexibility available within the system for those colleges who strive realistically to meet the needs of industry and the ambitions of students.

American Petroleum Institute recommendations for the design of tubular steel struts are represented in a series of convenient graphs. The graphs are intended for use in the initial stages of design, where various configurations are under consideration, and rapid weight estimates are required. R.S. Lamb

This paper considers the causes of masonry flue lining failures, mainly from tensile cracking of the outer face and/or compressive collapse of the inner face. Suggestions are offered as to both the most likely primary causes of failure in a range of commonly used lining materials, and ways of avoiding (or at least reducing the risk of) future failures, i.e. designing for durability. For freestanding linings operating within their tensile strength (very few), a series of design charts has been prepared to enable the maximum freestanding height of lift to be determined to avoid compressive collapse and failure.
