Description

Anordning for gruppevis forsinket tenning av minelauninger. Device for group-delayed ignition of mine launches.

Foreliggende oppfinnelse angår en anordning for gruppevis forsinket tenning av The present invention relates to a device for group delayed ignition of

mineladninger som er forsynt med elektriske tennere, hvor en elektrisk forsin-kelsestennsats er innrettet til ved forbren-ning å bevirke slutning av en elektrisk kontakt i strømkretsen av gruppens tennere. mine charges which are provided with electric igniters, where an electric delay switch set is designed to, upon combustion, cause the closing of an electrical contact in the circuit of the group's igniters.

For å tilveiebringe en gruppevis forsinket tenning av mineladninger anvendes To provide a group-delayed ignition of mine charges is used

en elektrisk utløsbar forsinkertennsats for an electrically deployable retarder gear set for

hver av gruppens mineladninger. Slike for-sinkertennsatser er imidlertid kostbarere each of the group's mine charges. However, such pre-sinker gears are more expensive

enn vanlige momenttennere, og hensikten than normal torque igniters, and the purpose

med oppfinnelsen er å tilveiebringe en en-kel og billig anordning for gruppevis forsinket tenning av mineladninger som er with the invention is to provide a simple and cheap device for group-delayed ignition of mine charges which are

forsynt med elektriske momenttennere. equipped with electric torque igniters.

Dette oppnåes ifølge oppfinnelsen ved This is achieved according to the invention by

at en elektrisk utløsbar forsinkertennsats that an electrically releaseable retarder gear set

er forsynt med en svak sprengladning som is provided with a weak explosive charge which

påvirker et stempel eller lignende, som på affects a stamp or the like, as on

den side som vender fra sprengladningen the side facing away from the explosive charge

har en elektrisk kontaktstift som ved ladningens detonering bringes i forbindelse has an electrical contact pin which is brought into contact when the charge is detonated

med en faststående kontakt. with a permanent contact.

Et utførelseseksempel på oppfinnelsen An embodiment of the invention

skal forklares nærmere under henvisning shall be explained in more detail under reference

til tegningen. to the drawing.

Fig. 1 viser skjematisk en anordning Fig. 1 schematically shows a device

ifølge oppfinnelsen. according to the invention.

Fig. 2 viser skjematisk anordninger Fig. 2 schematically shows devices

ifølge oppfinnelsen anvendt for gruppevis according to the invention used for groups

forsinket tenning av mineladninger som er delayed ignition of mine charges which are

forsynt med elektriske momenttennere. equipped with electric torque igniters.

Anordningen ifølge oppfinnelsen består The device according to the invention consists of

av en beholder 1 som inneholder et tenn-hode 2 hvis glødetråd tilføres elektrisk of a container 1 containing an ignition head 2 whose filament is supplied electrically

strøm gjennom ledninger 3. Til ledningene 3 er knyttet to ledninger 4 for en direkte 78 e-3 — 123270 — 1 blad tegninger. current through wires 3. Two wires 4 are connected to the wires 3 for a direct 78 e-3 — 123270 — 1 sheet drawings.

detonerbar gruppe eller en gruppe som de-toneres forsinket av en foregående anordning ifølge oppfinnelsen. Tennhodet 2 tenner en forsinkersats 6 som brenner med forutbestemt hastighet og etter et bestemt tidsrom tenner en svak sprengladning 7 som tvinger stemplet 8 med en kontaktstift 9 mot en stillestående kontakt 10 i enden av beholderen. Fra en av ledningene 3 er der avgrenet en ledning 5 og fra den andre av ledningene 3 dannes over kontaktene 9, 10 forbindelse med den an-nen av ledningene 5 for en etterfølgende anordning ifølge oppfinnelsen. detonable group or a group that is detonated delayed by a preceding device according to the invention. The igniter head 2 ignites a delay charge 6 which burns at a predetermined rate and after a certain period of time ignites a weak explosive charge 7 which forces the piston 8 with a contact pin 9 towards a stationary contact 10 at the end of the container. From one of the wires 3, a wire 5 branches off and from the other of the wires 3, a connection is formed via the contacts 9, 10 with the other of the wires 5 for a subsequent device according to the invention.

Fig. 2 viser tre grupper mineladninger som er forsynt med momenttennere 14, 15 resp. 16. Gruppen 14 tennes direkte og samtidig med disse tennes en anordning 11 ifølge oppfinnelsen, som etter en forutbestemt tidsforsinkelse tenner gruppen 15 og samtidig anordningen 12 for forsinket tenning av gruppen 16 osv. Fig. 2 shows three groups of mine charges which are equipped with torque igniters 14, 15 resp. 16. The group 14 is ignited directly and simultaneously with these a device 11 according to the invention is ignited, which after a predetermined time delay ignites the group 15 and at the same time the device 12 for delayed ignition of the group 16 etc.
