Tart Cards: London's illicit advertising art
No full textIn London, sex has been sold through advertising cards posted in phone boxes since the early 1980s. Some 13 million cards are produced each year, and at any one time more than 700 phone booths in Central London are used as ad hoc hoardings, advertising the whole gamut of deviance and desire. The range of ?services? offered by the cards depicted in this work range from A to V.I.P. Among the range of often esoteric services on offer are such delights as Sub, Dom, TV Shoplifters, Baby Cosseting and Busty, Black or Blonde. Tracing the history of these ephemeral items, Tart Cards provides an opportunity to explore a real example of the evolution of vernacular design and an insight into a sexual netherworld
The Kynoch Press: the anatomy of a printing house 1876-1981
No full textThe Kynoch Press, which flourished for over a century, had a reputation as one of the foremost printing houses of the period. The strength of the Press lay in its introduction of 19th-century English revival types into Britain during the 1930s. In its latter years the Press was innovative in embracing new opportunities, however, the economic recession of the 1980s forced its closure in 1981. This history of the Kynoch Press is enriched by personal accounts from surviving staff and also contains detailed listings of the types held by the press at every perio
Developments in characterization of resistance spot welding of aluminum
No full textAutomotive industry interest in aluminum is growing rapidly in Europe and North America. Resistance spot welding and weldbonding will be key techniques in the volume production of aluminum vehicles. A monitoring system has been developed to collect process data during single-phase alternating current (AC) and medium-frequency direct current (MFDC) inverter resistance welding. Features extracted from the captured data are used to characterize spot welding and to identify a range of process phenomena. Statistical analysis has been applied to investigate the relationship between the extracted features and the conventional physical parameters, e.g., weld size and static tensile strength. Welding trials using both MFDC and AC welding equipment have been carried out using aluminum of different gauges and surface conditions. Results on the Al-Mg alloy AA-5754 have shown that the monitoring methods developed previously for steel do not appear to be generally applicable to aluminum. No single parameter can accurately quantify weld quality. Multiple regression methods can, however, provide good prediction of nugget diameter and static strength. This has proved effective even when only electrical variables are logged, removing the need for measurement of other process signals, e.g., electrode displacement or force
