Abstract
1354282 Coated pyrophic cartridges RONSON PRODUCTS Ltd 19 April 1971 [26 Feb 1970] 9485/70 Heading B8C [Also in Divisions B2 and F4] A cartridge containing a pyrophoric substance and having an orifice through which the substance is discharged when the cartridge is in use in an ignition device, is enclosed in a removable protective skin formed of an impervious and fire resistant material, the skin preventing escape of the pyrophoric substance to atmosphere. The skin has a melting point below 150 C., preferably between 90 and 120 C., and comprises a polyamide resin, chlorinated diphenyl, which renders the material fire resistant, ester wax, which softens the material allowing it to be torn by hand, and N-butyl stearate, which prevents the skin bonding to the cartridge. The percentage by weight of the above components is preferably 54%, 32% 11% and 3% respectively. A tear strip comprising a polyester tape incorporating glass fibre strands is arranged beneath the skin with one end protruding therethrough so that it can be used to tear open the skin. The strip may alternatively be formed from other plastics, non-plastics or metal wire, The method of encapsulating the cartridge in the skin involves chilling the cartridge, dipping it into the material while molten, then plunging it into a cold water bath and finally allowing the skin to dry at room temperature. The tear strip is applied around the cartridge prior to dipping.
