From about 1930 onwards a new type of detonating fuse appeared on the market. This consisted of a core of PETN with textile and plastic coatings. Compared with Cordeau, this detonating fuse has several advantages in being more flexible, more easily jointed, lighter in weight and cheaper to manufacture. Under such names as Cordtex and Primacord it has completely replaced Cordeau in normal use. [Pg.121]

The first type to be introduced consisted of PETN or RDX in a metal sheath drawn down to a small diameter. More recently, cord made by the wet process, covered with plastic instead of metal, has been introduced in North America and is available in charges down to 0-6 g m. The methods of manufacture of these cords are believed to be similar to that of Cordeau and the wet detonating fuse process described above. [Pg.124]

An early French Detonating Cord (called Cordeau detonant, module 1902) consisted of a tin tube filled with a PA core. The external diam of tube was 5.4 mm and the vel of deton of the cord was 6690 6745 m/sec. About 1907 L. Lheure of France introduced commercial Cordeau. It consisted of a lead tube filled with TNT or Tetryl. [Pg.313]

Its vel of deton was 5110 m/sec. This type of Cordeau was introduced in US by 1913 by the Ensign-Bickford Co, Simsbury, Conn (Refs 1, 3,5,7a, 10 14). See also Cordeau Bickford under Bickford Fuse or Miner s Safety Fuse,... [Pg.313]

Snelling Koch (Ref 2) patented a Cordeau in which molten TNT was poured into a lead tube. After the tube cooled, it was subjected over its entire circumference to the action of rapidly moving hammers, whereby its length was increased and its diam decreased. By this method the TNT was reduced to a finer state of division and consequently became more sensitive to initiation. Such a Cordeau is reported to be smoother stronger than when the Pb tube is drawn or rolled... [Pg.313]

A Hexanitromannite Cordeau, proposed by Sebert Fritsch to the Poudrerie a Sevran-Livry, developed a vel of deton of 7000 m/sec, but was considered too expensive too sensitive for coml use (Refs 3 5) More recently the SA D Explosifs et de Produits Chimiques manufd a Cordeau consisting of flat hollow Pb bands filled with Tetryl. It is claimed that flat Cordeau is easier to introduce into a bore-hole than round Cordeau. Other models of Fr Detonating Cords employing a PETN core a fabric cover are called Cortex, OD 4.8mm, gms of expl/m 8 vel of deton 5990-6410 m/sec and Eclair, OD 5.5 mm, gms of expl/m 11 vel of deton 6355-6745 m/sec.
