Aircraft factories

One of the most significant recent aircraft is the Rutan Voyager, an all-composite plane in Figure 1-42 which was flown around the world non-stop in 1989. Burt Rutan of the Rutan Aircraft Factory created a seemingly endless line of all-composite aircraft in the 1980s and 1990s. 

In 1937 rivets containing a small explosive charge in their shanks were constructed (Aircraft Factory Heinkel and Rheinisch-Westphalische Sprengstoff A. G. [131]). The composition of the explosive mixture is so selected that a slight explosion occurs on heating the head of the rivet with a hot iron. The explosion causes an expansion of the shank thus fixing the rivet in place. Explosive rivets have found wide application primarily for riveting aircraft components in which rivets are not accessible from both sides of the riveted surface. 

Magnesium and aluminium are used extensively in making aircraft. In metal tool workshops in aircraft factories, magnesium and aluminium dusts get accumulated. The magnesium and aluminium dusts react with the oxygen in the air of the workshop and spontaneous combustion occurs. 

Vibration sensation thresholds were used to assess functioning in 29 aircraft factory workers chronically exposed to jet fuel vapors and who reported symptoms consistent with peripheral neuropathy (Knave et al. 1976). The exposed subjects were classified into two groups heavily exposed (n = 13) and less heavily exposed (n = 16) and were compared with unexposed controls. Comparison of the subjects from the high-exposure group with controls revealed significant differences on vibration sensation thresholds. 

The initial German air attack, the Battle of Britain, began in mid-August a month of ferocious daylight contests between the Luftwaffe and British Fighter Command for air supremacy in advance of Operation Sea Lion, Germany s planned cross-Channel invasion. It was not yet an attack on cities. British airfields and aircraft factories were primary targets. Hitler... 

In these patients, the specific immunoglobulin E (IgE)-mediated immediate sensitisation from DGEBA with a MW of 340 Da was revealed. Recently, Sasseville (1998) reported on a patient who presented with contact urticaria while working in an aircraft factory. On patch testing, at the 30-min reading, he suffered urticarial reactions to epoxy resin (1% pet), phenylglycidyl ether (0.25% pet) and cresylglycidyl ether (0.25% pet). No delayed reactions were seen. Similarly, Miyamoto and Okumura (1998) reported on contact urticaria confirmed by a 15-min open test and a 15-min closed patch test for epoxy resin at 1% in petrolatum. 

An outbreak of dermatitis that occurred in an aircraft factory was caused by o-diglycidyl phthalate, among other chemicals [8]. Burrows and Rycroft have reported contact allergy to tricresyl ethylphthalate in a plastic-nail adhesive [9]. Phthalates can also appear in deodorant formulations, perfumes, emollients and insect repellents [10]. Triphenylphosphate allergy from spectacle frames has been reported [11,12].

After starting the project CWS learned that the British had already determined the best size for high altitude droplets and were adding various substances to mustard to increase the particle size. In co-operation with the NDRC the CWS tested more than seventy thickeners. Finally, the search narrowed down to polystyrene and methyl methacrylate. After methyl methacrylate sheet scrap (Plexiglas and Lucite) became available from aircraft factories, the CWS adopted it as a mustard thickener. ...
