A cylindrical drive member is arranged concentric with respect to the rolling surface and is connected to the housing through a fixed bearing. Pinch rollers are provided which roll along planetary-gearlike on the rolling surface and on a hose in the groove and are driven by the drive member sun-gearlike through frictional resistance. The pinch rollers are constructed as resilient and hollow cylinders.

Abstract: A warhead with a disintegrating jacket to house several projectiles, in picular splinter projectiles. The projectiles are each equipped with an ignition and backfiring system and fall to earth individually after disintegration of the warhead jacket. They are then fired upwards by means of the backfiring charge ignited by the ignition system, the charge explosive then being detonated. The ignition system of each projectile consists of a time-delay fuze and an impact fuze. The time-delay fuze is initiated when the projectile impacts with relatively soft ground and ignites the backfiring charge after adjusted times differing at least partly for the individual projectiles. The impact fuze, however, effects an immediate ignition of the backfiring charge when the projectile strikes relatively hard ground.

Abstract: A warhead for use against armored targets, comprising a shaped charge and aftereffect caused by a second annular explosive charge located in front of the shaped charge, with the explosive charge arranged at the base of a hollow body (nozzle) tapered in target direction. A funnel-shaped sleeve is disposed between the shaped charge and the second explosive charge, and detonation transmission elements are arranged on its outer circumference. The jet from the shaped charge passes the second explosive charge prior to the latter's detonation. Behind the hole produced by the shaped charge jet an aftereffect takes place which is caused by the active mass flow accelerated in axial direction by the second explosive charge.

Abstract: A combustion chamber system for the production of propelling gases, partiarly for propelling projectiles includes a tubular member defining a combustion chamber which is adapted to be located adjacent one end of a gun barrel having a passage for a projectile. A piston is slidable in the combustion chamber toward and away from the projectile and it includes a ring portion of wider diameter which is movable in a widened portion of the tubular member defining the combustion chamber. Propellant components are introduced into the combustion chamber by the movement of the piston which is effected by the combustion of the gases within the combustion chamber. For this purpose, the combustion chamber is connected through passages defined in the piston and fixed end plates of the combustion chamber which extend to supply tanks for the various propellant components.

Abstract: A method and circuit arrangement for changing the sensitivity of the measng range in a device employing delta modulation in a navigation system. The device uses an integrator for integrating a measured value from a sensor, a threshold detector following the integrator, a synchronizer responsive to the threshold detector and a pulse transmitter driven by the synchronizer. The pulse transmitter provides a reset pulse with appropriate release time to reset the integrator, the reset pulse being counted by a counter fed to a navigation computer. A switching arrangement at the input of the integrator operates to change the sensitivity or scale factor. Switching is controlled by logic circuitry which responds to the level of the measured value as well as the output of the integrator. The reset pulse release time is also employed as a switching criterion.

Abstract: The pressure drop in a pressurized cabin, for example, in an aircraft cab is delayed following the occurrence of an emergency resulting from a door failure, by a mat which has a low air permeability. Such a mat is mechanically secured to the cabin structure to cover the openings in the cabin or body on the inside thereof, for example, to cover a door opening in flight. The air permeability of these mats is such that a pressure equalization is delayed by a time safe enough for humans, whereby the pressure equalization rate does not exceed approximately 2.4 PSI/sec.

Abstract: In the disclosed method of forming shaped objects by a powder-metallurgical rocedure, a dummy or sample of a meltable material, such as wax, is prepared which has generally the configuration of the ultimate shaped object to be produced. A self-supporting layer is then electroformed on the dummy object to enclose the latter. The dummy object of wax or the like is then removed by melting, whereby a hollow space or cavity is formed which is defined by the layer and which corresponds to the configuration of the dummy object. Metallic powder of a type used in powder-metallurgical procedures is then filled into this space under vacuum and is subjected to hot isostatic pressing or compaction to densify and compact the powder, thereby to form the ultimate shaped object. The electroformed layer is thereafter removed and, if necessary, the object is further finish-worked in any suitable manner.

Abstract: A method for the separation of segregations from material mixtures is dissed. The method is particularly suited for the sedimentation of high-melting metal alloys and their impurities. In the method, material mixtures are introduced into the heatable rotor of a centrifuge disposed in a cooled vacuum. The rotor is subjected stepwise to the influence of changing gravitational accelerations as well as to a heat shock treatment varying in temperature level and/or duration. Equipment for execution of the method is also disclosed. The rotor of the centrifuge consists of several layers and includes a basic part whose outer surface is braced by a compound material bandage. The inner surface of the rotor is provided with a heat-deflecting, protective coating. A non-rotating cooling means and a central heat source are accommodated inside the rotor.

Abstract: One of two races of a roller bearing is equipped with a sliding ring exteng thereabout, with a melting ring formed of material having a melting point higher than the normal operating temperature of the bearing being interposed between the one race and the sliding ring. Malfunction of the bearing such as might occur by seizure of the bearing rollers will cause at least partial melting of the melting ring whereupon the one race is placed in relative sliding engagement through the melting ring with the sliding ring.

Abstract: A protective armament or intercept system includes a plurality of explosive harges arranged in a grid pattern in spaced parallel relationship to a grid sensing pattern formed by intersecting light sources each of which are aimed at respective photoelectric cells. The light sources and the photoelectric cells form a protective and sensing field with intersecting points which are in alignment with respective explosive charges and when the light sources at an intersecting point are broken, the receiving photoelectric cells for the broken light sources will be influenced so as to ignite the charge which is in alignment with the broken intersection point of the light sources. The construction of a preferred explosive charge and the various preferred arrangements of the explosive charges in respect to the sensing pattern formed by the photoelectric cells and light sources are set forth and described in respect to the protection of an aircraft hanger and a movable vehicle such as a tank by way of example.

Abstract: In a shock absorber assembly for a vehicle, a closed flexible hollow body mounted on a rigid support member, such as a part of the vehicle understructure, and a highly compressible fluid medium, for instance air, is filled into the hollow body. Another rigid support member of closed hollow construction is mounted against the opposite side of the hollow body from the support member on the vehicle understructure. The hollow support member can be lined interiorly with a closed bladder-like member and connected by a throttling member to the hollow body to act as an equalizing member when the hollow body is compressed by shock forces. As an alternative, two similar shock absorber assemblies can be spaced apart on a vehicle with each including one of the closed flexible hollow bodies and with the throttling member connected between the hollow bodies in the separate shock absorber assemblies.
