Abstract
552,223. Blasting detonators. DU PONT DE MEMOURS & CO., E. I. July 25, 1941, No. 9453. Convention date, July 25, 1940. [Class 9 (i)] Electric blasting initiators such as electric blasting detonators or delay initiators of the bridge-plug matchhead and bridge-plug bead-types, are sealed by resilient plugs 2 of compositions based on natural or synthetic rubber moulded around a pair of brass or brass-coated leg wires 6 spaced apart from each other and the plug is then crimped into the mouth of the detonator casing. The plug may consist of vulcanised rubber and the rubber is placed around the separated brass wires and is vulcanised thereon. The composition should have an elasticity not less than 30 and preferably about 90 as indicated by a durometer of type "A" of the shore Instrument Co. and a plasticity of between 150 and 200 as measured on a William's plastometer, the pulling-out strength between the plug and the wires varying between 12 and 23 pounds. A suitable rubber composition for the plug is:- Specifications 523,217 and 527,742 are referred to.
