Figure 1 shows Jones results (Ref 3) of his study of critical firing energies for electric fuse-heads (also known as matchheads). The data in Fig 1 are for an 80/20 LMNR/KC103 ignition mixture (LMNR is Lead Mononitroresorcinate). [Pg.278]

Anon, Atlas/Aerospace No 8, 1969, Atlas Chemical Ind, Valley Forge, Pa 19481 reviewed by G. Cohn, Edit in Expls Pyrots 3(3), 1970 under the title Explosives for Actuators [LMNR (Lead Mononitroresorcinate), KDNBF (Potassium Dinitrobenzofuroxane) and BaSt (Barium Styphnate) are the three common materials used as either ignition drops or base charges in actuators, motors, switches, and matches. LMNR, a stable, low-cost compd, is always used with 5 to 40% KCIO3. KDNBF, a higher cost material, is 5 to 10 times more powerful than LMNR. [Pg.336]

A study was undertaken with a view to determine the basic mechanism of failure in series firing ability. The excitation time, transfer time and total rime of three different types of squibs (i) with LMNR as base (ii) with Lead Dimtro-ortho-cresol (LDNOC) as base and (in.) with charcoal plus potassium chlorate as base were determined...

Electrical Firing Properties of Some Lead Compounds of Nitrated Resorcinol. Lead Mononitroresorcinol (LMNR), PbC CgH NO ) (See p D1271-L in this Vol), used in electric squibs has a lead content betw 68 77%. [Pg.666]

The transfer time of such.squibs was found by Rao et al (Ref 1) to be ca 1.5msecs. In order to vary its Pb content, pptn was conducted under different conditions. The resulting compds showed no variations of burning characteristics and hence in transfer time. In this respect LMNR seemed to behave similarly to Lead 4,6-Dinicroresorcitiol (4,6-LDNR), Pb02C5H2(N02)2 (See p D1275-R in this Vol)... [Pg.666]

There are also electric squibs which.are used for military purpose. One such device is the US Navy All-Purpose Mkl Electric Squib", shown as Fig E21. It comprises a gilding metal or A1 case (3), contg Pt-Ir bridge wire (4), surrounded by the ignition bead (5), winch may be LSt(Lead Styphnate), LA(Lead Azide) or LMNR(Lead Mononitroresorcinate) + KC103 (95/5). The bridge is connected to two leg wires (l), which pass thru a phenolic plug (2). [Pg.702]

Primary explosives have a high degree of sensitivity to initiation through shock, friction, electric spark or high temperatures and explode whether they are confined or unconfined. Typical primary explosives which are widely used are lead azide, lead styphnate (trinitroresorci-nate), lead mononitroresorcinate (LMNR), potassium dinitrobenzo-furozan (KDNBF) and barium styphnate. Other primary explosive materials which are not frequently used today are mercury azide and mercury fulminate. [Pg.26]

The following results are listed Barium Styphnate 12, LMNR (Lead Mononitroresor-cinate)16 and KDNBF (Potassium Dinitro-benzofuroxan) 14... [Pg.388]

It was found that for the charcoal based squib, the transfer time was almost double the initiation dme. This large transfer time obviously takes care of the variations in the excitation timings due to different factors in the manufacture of squibs. This ensures continuous flow of current thru all the squibs connected in series until, the time the most sensitive squib breaks the circuit. In the case of LMNR and LDNOC fuseheads the transfer time was found to be quite low and the total time of some of the fuseheads was less than or equal to the excitation times of some others in the same group. Such squibs when connected in series caused failures in r.eries firing. As a confirmation to this theory, a retardant was introduced in the LMNR fuse-heads to increase the transfer lime, and no misfires were noted... [Pg.632]
