VISUAL DESCRIPTION
This is an advertisement for the De Bergue Patent Countersunk Riveting Process. The image shows a 150-gallon capacity wing superfuel tank produced by Supermarine Aviation Works (Vickers) Limited, which has been constructed using this particular riveting process. The ad highlights that this method contributes to the safety and performance of practically every important British aircraft, whether military or civil. The advantages listed include: - Enables Drill or Mold taps to be built approximately half the thickness of Tinned Steel tanks, and many stages of construction are not required. - Time saved in making unnecessary flanging surfaces on Dies, which can be utilized by various sizes up to specifications. - Joggled edges are avoided from leaking by being entirely free from fastenings. - As they stay at one pressure level throughout their life cycle, these joints retain strength and can be accurately calculated. It's noted that this process has been adopted by practically every firm engaged in constructing fuel tanks for flying craft worldwide. The advertisement concludes with contact information for De Bergue's Patents Ltd. , located at Strangeways Ironworks in Manchester.
