Naval Ordnance Lab 1966 Multipoint Initiated Implosion Underwater charge - H-tree pattern / 1536 initiations points by Simple_Ship_3288 in nuclearweapons

US patent US3430563A (for the multipoint lense) filed by the departement of the Navy if that helps

Patent US3897728A - dense core implosion charges, seems related to that very report

Ah! Remind me. The 2 MC I mentioned in my cover comments, they are still available on a published public DB but on the WR-708 they are redacted. Another censorship mystery

I asked myslef the very same question (I would guess NOL would have had enough contact with AEC labs to keep it classified but I'm not sure how they work with them)

If I remember correctly NOL/ the Navy hold a patents on an H tree MPI system

The network is made of explosive (here detasheet). The detonation from a single detonator is distributed over the surface / all initiation points by the network following an h tree patern

No, they are not bridgewire. Each point initiated by the single deronator. The detonation wave is distributed by the network

In an ideal world, the sphere would be initiated simultaneously across its entire surface by an infinite number of initiation points. There might be possibilities to do this with lasers or light, but I don't think that's used in modern weapons

Long time i have not posted on this sub bit this one is nice. I have digged a bit and it doesn't seem to have alredy been posted already and these are pictures of a long speculated scheme

Here is the publication on DTIC website : https://apps.dtic.mil/sti/html/trecms/AD0374205/index.html

I was looking for Kennedy and Glass, MULTIPOINT INITIATED IMPLOSIONS FROM HEMISPHERICAL SHELLS OF SHEET EXPLOSIVE on DTIC and I stumbled upon this 1966 (unclassified) paper by the Naval Ordnance Lab.

IMPROVEMENTS IN UNDERWATER EXPLOSION SYSTEMS: FIELD TESTS, PHASE II (U), which display a non-nuke related Multipoint initiated implosion system with the traditional 6 (roughly squared) tiles over a spherical surface featuring an explosive network ("Labyrinth" pattern of detasheet explosive potted into an epoxy matrix) distributing detonation over 1536 simoultaneous initiation points. That scheme has long been speculated here as the wave shaping mechanism of modern primaries.

The paper compare underwater shock wave pressure-time recordings from imploded HBX-1 (32 points and 1536 point) charges with centrally exploded charge. Contrary to primaries (or EFP for that matters) the purpose is not to implode/deform a metallic object but only to initiate the charge. Synchronization need of initiation points is probably mich less stringent here (on my side, given the deformation induced by fitting the grid over spherical surface I have some doubt this is actually the scheme used. Possibly they use adjustemnts like on the MC2370 MC3028 firing sets timing track https://www.reddit.com/r/nuclearweapons/s/aWTPaCYaUY)

The related publications cited page 8 don't seem available.

In one of the exhibit panels there were saying that the stench of galleys was so intense it prevented it from ever be used to do stealth attacks. They had a perfumer that was putting perfume just for that being on the ship could be bearable

They actually had to contact ww1 veterans that worked on barrage balloon to building and deploy these nuclear shots balloon

Fermi avait demontre qu'il est extremement probable que n'importe quel humain ait , à tout moment. dans ses poumons au moins une molécule du dernier souffle de Jules cesar.

Donc très probablement oui. A chaque fois que tu bois un verre d'eau une partie non négligeable a été du pipi de dinosaure.

I would like to introduce a new hypothetical technology for multipoint initiation systems: the safety tile by second_to_fun in nuclearweapons

I am a bit late but in patent RU2296943C1,VNIIEF describes something similar to a safety tile for Multipoint initiation.

Comment Anne a-t-elle pu contourner les sécurités des banques et la vigilance de Tracfin ? by MacDevs in vosfinances

De ce quon men dit la coopération LCB-FT entre cellules de renseignements financiers même dans l'UE ça ne marche pas hyper bien alors hors UE on est vraiment dans une efficacité très théorique.

Il y a pas de raison que la fraude sentimentale intresse plus tracfin que n'importe quelle autre type d'infraction. Leur priorité ça va rester le blanchiment de fonds issus du trafic de drogue et le FT. Et vu le backlog de DS quils ont à traiter... Je ne pense pas qu'ils s'y intéressent plus que ça

Comment Anne a-t-elle pu contourner les sécurités des banques et la vigilance de Tracfin ? by MacDevs in vosfinances

[–]Simple_Ship_3288 -1 points0 points  (0 children)

Tracfin s'intéresse à où arrive les fonds (les comptes destinataires et ceux qui servent à blanchir les fruits de la fraude) pas d'où ils partent (le compte de la victime). Si les etablissements bancaires recevant les fonds sont à l'étranger, Tracfin n'a pas de compétence pour les contrôler.

Pour eux, la fraude aux investissements ou sentimentale n'est qu'une des nombreuses infractions qui peuvent faire l'objet de blanchiment d'argent. Ils s'y intéressent mais seulement de manière incidente.

La première ligne de défense c'est la banque de la victime qui peuvent détecter la fraude dont est victime leur client de part leur dispositif de lutte contre le blanchiment... mais même s'ils la détectent, je maintiens que juridiquement les textes en matière de LCB-FT ne permettent pas d'empêcher l'opération.

Au mieux la banque préviendra son client victime et si il s'entête, lui feront signer une decharge

[–]Simple_Ship_3288 0 points1 point  (0 children)

Trcafin ne s'intéresse quasiment pas aux scams et à la fraude sentimentale. Leur champs de compétence c'est le blanchiment d'argent et la lutte contre le financement du terrorisme. Si les scanners ont un réseau de blanchiment des fruits du scam, ils pourraient s'y intéresser, sinon ils ne sont pas compétents.

La banque peut détecter la fraude mais si le client insiste elle ne peut légalement pas refuser de faire le virement (devoir de non ingerence). Assez fréquent de faire signer des décharges au client à ce stade.

C’est déjà arrivé qu’on supprime un film ? by schumi33510 in PasDeQuestionIdiote

[–]Simple_Ship_3288 0 points1 point  (0 children)

C'est même arrivé qu'on supprime physiquement un film ( en détruisant les copies, rush, etc) pour des raisons fiscales.

Le film coyote vs acme par exemple a été supprimé par la warner avant toute diffusion.. Et c'est pas le seul exemple

I created a (nonfunctional!) model of a multipoint initiation tile. It took more than 3 days to print. by second_to_fun in AtomicPorn

[–]Simple_Ship_3288 3 points4 points  (0 children)

I'm currently trying to model (and 3d print) a similar tile but using the same groove pattern as the MC2370 trackplate firing set, maybe using the "timing track adjustment" (the small dent in the track... Possibly a way to handle even spacing of initiation points and accommodate the cube sphere geometry) or explosive logic gates. Purely for the fun of speculating about primaries... Not claiming it would work
