f LIGHT International, JO May 1962 761 INDUSTRY International Products Company News Products Nylon Airlift The three webbing strops used by the Belvedere of 72 Sqn for lifting a 1,3101b sculpture to the roof of Coventry Cathedral (Flight International, April 26) were manufactured by the GQ Parachute Co from nylon webbing with a breaking strength of 4,5001b. Each of the three strops—one lift and the other two 7ft long—had a minimum breaking strength of 8,0001b, about six times the load im posed by the sculpture. Metal Joining Services A confident claim —"it is believed that every British missile in service today contains parts that have been processed in our salt bath, which is heavily committed to the guided weapons pro gramme"—is made by Delaney Gallay Ltd in describing the metal joining facilities offered at their Vulcan works, Edgware Road, London NW2. The bath referred to, for light alloy brazing, and a vacuum furnace for brazing mild or stainless steels, give the company an exceptional standing among UK firms in being able to provide both types of brazing. In order to take full advantage of these facilities, the company have in the past year fitted their laboratories with the latest types of equipment, including Vickers projection microscope and hardness machine; Cook Troughton and Simms bench microscope; Universal Avery impact machine; Dennison tensile testing machine; Erichsen cupping test machine; and analytical equipment. Brazing and heat treatment have been carried out for several industries, including aircraft and electronics. For several years Decca Radar have entrusted Delaney Gallay with the brazing of waveguide assemblies used in their airborne systems; more recently, the company have under taken similar operations on components in aluminium, Inconel and mild steel for a new type of Sperry gyroscope. Runway Paint A new catalysed epoxy- type road marking paint recently introduced by Jenson & Nicholson Ltd, Carpenter's Road, Stratford, London El5, in their "Epilac" range has been described as having the advantage of improved resistance to blast from jet engines, besides being resistant to petroleum products, lubrication oils, grease, water and humidity. Con siderable interest has been expressed in the paint for use on overseas airfields. It has a pot life of one to two days after mixing, with a surface drying-time of about one hour at 50-60°F but less at higher tempera tures. It is suitable for spray and machine application and obtainable in yellow and white. Expanding Hangars New techniques have been used by Taylor Woodrow Construc tion Ltd to enlarge a hangar for Aviation Traders (Engineering) Ltd at Stansted Airport, Essex, to enable it to accommodate two Britannias. The existing structure, an Air Ministry T.2 type, portal-framed and some 117ft in width, has been extended by two pockets, each 36ft wide and 40ft deep, along one side of the hangar so that the two aircraft, which have wing spans of over 142ft, can now be housed nose-to-nose. A hanger at Stansted extended by pockets to accommodate the wings of two Britannias positioned nose-to-nose; and, right, interior of a hangar at LAP extended to accommodate a similar aircraft— the additional section can be identified above the fin (see news-item above) After the construction of heavy founda tions and the stripping of wall cladding, the work involved reinforcing the existing steel frame—joints being reinforced by welding at possible positions of high stress —and the erection of new steelwork, which was pre-loaded to take up the reactions on the existing structure. The new and the old work were then spliced together by bolted channels and, finally, four existing legs at each end were cut away so as not to obstruct the entrance of the wings. The work was completed in just over six months, Taylor Woodrow Construction Ltd (whose HQ are at Ruislip Road, Southall, Middx) being responsible for design as well as construction. The method adopted was found to be cheaper and quicker, and to provid: more accommodation than alternatives considered. Another hangar enlarged by the company was that of Cunard Eagle Airways at London Airport. The structure was ex tended in width in the entrance area from ...
