Abstract: A scaffolding mast with at least two profile bars (1, 2, 3) which are attached to the edges of a triangle or square forming the cross section of the scaffolding mast. Two of the profiles (1, 2, 3) are connected to one or two of three connecting plates (10, 17, 18) forming the side of the triangle or square. Two grooves (4-9) are provided on the inner area of each of the profile bars (1, 2, 3) in which 90.degree. offset edges (13, 14) of the connecting plate (10, 17, 18) are inserted and fastened at the place of insertion (FIG. 1).

Abstract: A lifting scalfold assembly with several scaffolding poles which stand on a base and which are extendable in length and, between which mobile platforms are situated such that they can be adjusted in height, whereby the scaffolding poles are attached to a building by means of holding supports each scaffolding pole includes at least a girder section housing which at least a gear rack on an inside and a gear rack on an outside thereof. On the mobile platforms cogwheels and drives for the cogwheels running on the outer gear racks are provided. A sliding module or carriage includes cogwheels and drives for the cogwheels running on the inner gear connected to the girder section. Conduction rails are included on the scaffolding pole, and current collectors are positioned on the connectable mobile platforms and the sliding modules.

Abstract: A multicomponent attachment apparatus for a movable working device which is detachably attached to the front end of the working device, including a device-sided adapter in order to connect the attachment to the working device, a building component-sided supporting member with holders to pick up, move, hold and deliver a building component, and intermediate pieces between the adapter and the supporting member, whereby the intermediate pieces are connected movably together and to the adapter and the supporting member and include a lifting module (1) which is connected to the working device and can be vertically adjusted and fixed in position at any desired height with respect to the working device by a lifting drive; a sliding module (4) movably mounted to opposite sides of the front of the lifting module (1) and movable by a sliding drive and stoppable in any desired side position; a spacing module (10) mounted to the front of the sliding module is movable in a longitudinal direction of the working device by m

Abstract: This task is solved according to the invention by a design corresponding to the characteristic of the claim. The inert insertion according to the invention has the shape of a cylinder with a cone or truncated cone-shaped extension whereby the transition from cylinder to extension takes place without break. The inert insertion is to be arranged in the explosive of the shaped charge oriented such that it points with its free end tapering to the cone tip or top surface, respectively, of the truncated cone in the direction to the primer charge and correspondingly with its cylindrical part in the direction to the lining of the shaped charge. This inert insertion from cylinder and cone or truncated cone, respectively, has been shown to be especially favorable in comparison to the well-known forms of inert insertion. The effect of shaped charge rounds equipped with it on modern multiplate targets was significantly better than those of charges with inert insertions of conventional form.

Abstract: Explosive charges are compacted under low pressure to form a shaped preform which is then further compacted under higher pressure in a manner which provides a homogeneous finished product.

Abstract: A process for producing a compacted large-caliber explosive charge, including a primary charge and a prefabricated propagation charge, involves compacting the primary charge and the propagation charge together within a casing, housing or the like structure.

Abstract: A method for the continuous manufacture of explosive mixtures by mixing their components in screw mixers with at least one charging aperture. Proportioned amounts of the components of the mixture are brought into entry zones provided with screw elements and situated below the charging aperture. The mixture components are then advanced through alternation kneading zones and transport zones having screw elements to the output end. The transport and kneading zones are configured such that the shear gradient therein is between 20/sec and 1500/sec and the maximum pressure in the stream of the mass is not more than 100 bars.

Abstract: A process for producing flexible formed explosive charges includes the steps of admixing at least one elastomer which exhibits an elongation of at least 800% and a tear strength of between 50 and 350 kp./cm.sup.2, at least one high-brisance explosive component and at least one plasticizer that has a melting point of less than -20.degree. C. and that does not substantially evaporate up to a temperature of 90.degree. C. and thereafter forming the resulting admixture into a shaped or formed explosive charge. The high-brisance explosive component has a detonating velocity of at least 6000 m/sec.

Abstract: A high energy explosive composition comprising an inorganic oxygen supplying salt, a metallic fuel and a eutectic mixture comprising an oxygen supplying salt and a combustible compound capable of lowering the solidification point of the oxygen supplying salt in admixture therewith in the eutectic composition; a eutectic composition comprising an oxygen supplying salt, a compound capable of reducing the solidification of said oxygen supplying salt and in admixtured therewith at least 30% by weight of a composition comprising an alkanolamine nitrate or perchlorate.
