Abstract: The present invention comprises a method and apparatus for filling a space in at least one ammunition unit with a ready-mixed explosive containing a substance which imparts high viscosity to the explosive. The method comprises supplying the explosive into a flexible container with a single opening therein, positioning the flexible container into a second container adapted to withstand high internal pressure, applying a high pressure into the second container thereby exposing the flexible container to the high pressure, and pressing out the explosive from the flexible container through the opening in the flexible containers into the space in the ammunition unit upon application of the high pressure whereby filling the space with the explosive.

Abstract: The present invention relates to a method for producing, by means of working, mixing and homogenizing, castable explosive substances of high viscosity containing crystalline and/or particulate explosives and, if appropriate, other action-enhancing additives and such small quantities of binder and other viscosity-reducing agents that the mixture in the unworked state virtually feels like and behaves like a dry powder. In order to achieve the desired working, mixing and homogenizing, use is made of an arrangement which is known per se.

Abstract: The disclosure relates to a method and a device for producing compositions comprising fine-grained crystalline explosive substances with the aid of a steam-driven ejector (22). The expression explosive substances is here taken to mean both low and high explosives.

Abstract: The disclosure relates to a method of producing charges for cannons with extremely high charge density and favorable burning properties from the standpoints of both wear and pressure vs time characteristics. According to the invention, the charge is formed of mutually parallel, bundled tubular propellant rods which have been provided with specially designed rupture points which cause the charge to be ignited as a pure tubular propellant charge of large length in relation to the diameter of the combustion channels, but finally burns as a pure granular propellant. The disclosure also relates to propellant charges produced according to the disclosed method.

Abstract: The disclosure relates to a method of initiating a crystal growth prior to filtering off, from the mother liquor in which they were produced, of such crystalline explosives of the type hexogen and octogen produced by the so-called Bachmann process or variations of this process.According to the invention, the mother liquor is, after the end of the chemical reaction proper, subjected to a pressure-heat treatment which initiates the partial dissolution of the crystalline explosives obtained in the process, giving rise, after cooling of the mother liquor, to larger crystals which may more readily be filtered off.According to a further improvement of the invention a relatively pure octogen may be extracted from the mother liquor by way of a thermo-filtering of said liquor at a temperature of 60.degree.-110.degree. C.

Abstract: The disclosure relates to a propellant charge for cannons comprising bundles (11) of tightly held tubular propellant sticks which are provided with connections between the propellant sticks' outer surfaces and their combustion channels, these connections consisting of either longitudinal slits or of uniformly spaced, weakened points in the form of perforations, slits, open notches or bored holes which extend from the outer surfaces of the propellant sticks to the combustions channels, the bundles (11) being surrounded by disoriented powder flakes, powder grains or short powder rods or tubes (9), these filling the remaining portion of the combustion space (7).The disclosure also relates to a method of producing such a charge.

Abstract: The disclosure relates to a method of producing 5-amino salicylic acid from salicylic acid, with sulphanilic acid as the recyclable auxiliary chemical.The method according to the present invention includes linking between the diazonium salt of the sulphanilic acid and the salicylic acid, followed by a splitting by hydrogenation with hydrogen gas and catalyst, and selective precipitation of the desired product.

Abstract: A detonator for non-electric detonation systems for blasting charges intended to be initiated by a detonating fuse includes a passage provided in the body of the detonator for passing a detonating fuse through the passage. The detonator includes a conventional percussion cap which is immediately initiated by the detonating fuse for initiating the detonator. Also a booster charge intended for the detonator is provided with a reinforced central channel for the detonating fuse.

Abstract: The disclosure relates to an explosive charge intended for the explosive jointing of, primarily, large-diameter pipes, such as pipeline pipes. The charge according to the invention is intended to be delivered as a unit ready to be applied immediately on site in the pipe. The only item which is not intended to be included is the detonator which is mounted in place immediately prior to blowing the charge. The charge includes, apart from explosive, also a polymer binder of a more closely defined type and gas blisters preferably in the form of microspheres of glass or plastic and metal or metal oxide powder. The scope of the invention embraces the general configuration of the charge and all components included therein.

Abstract: The disclosure relates to a method for producing composite explosives of the type hexotonal and octonal by the intermediary of a two-stage wet granulation process comprising a first granulation stage for producing primary granules of a certain amount of TNT (the primary TNT) suspended in water, together with other desired components in the explosive, with the exception of the aluminum powder, which, in its turn, is mixed into the remaining amount of secondary TNT in order thereafter, in a secondary granulation stage, to be added to the mixing water with the primary granules suspended therein, for a successive build-up of their surface layer.

Abstract: The disclosure relates to a method for producing charges for explosive jointing of large-diameter pipes such as pipelines. According to the invention, such charges are formed in that a strip-shaped flat explosive is wound and joined together to form a circular ring of even thickness consisting of a plurality of closely abutting layers.

Abstract: The disclosure primarily relates to a method of phlegmatizing crystalline or otherwise particulate explosive substances or compositions in which these are included, by first coating the discrete particles with a thin layer of oxazolin wax in order thereafter to carry out a conventional wet-granulation with a true phlegmatization agent or a binder agent, such as one of the wax types included under different explosive standards or a plastic composition. The invention also concerns products manufactured according to said method.

Abstract: This invention relates to a method of manufacturing ortho- and para-nitrobenzaldehyde from o-chloro or o-bromobenzaldehyde and p-chloro or p-bromobenzaldehyde respectively through a nucleophilic aromatic substitution reaction performed in an organic solvent.
