Abstract:
A loading device for containers (C) comprises a pair of loading units (2), each having a telescopic column (4) supported on a bracket (3) so as to be swivelled about a common swivel axis (I). The telescopic column consists of a lower portion (9), an upper portion (11) and a column cylinder (17) moving the upper portion (11) with respect to the lower portion (9). Actuating cylinders (5) are connected to the lower portion (9) on both sides, and the upper portion (11) accommodates an extension arm (14) which can be swivelled about a swivel axis (III) parallel to the swivel axis (I) of the telescopic column. To expand the loading possibilities, the upper portion (11) carries a column head (12) which forms a slot-shaped swivel guide (18) with cam tracks (19) limiting the swivelling of the extension arm (14). The extension arm (14) has guide members (20) and is pivotally connected with a sliding piece (13) movably seated inside the upper portion (11) which opens towards the swivel guide (18), where a constriction (21) is provided between the cam tracks (19), so that the guide members (20) of the extension arm (14) aligned in a position stretched with respect to the telescopic column (4) simultaneously contact both cam tracks (19), and on the side of the upper portion the column cylinder (17) acts on the sliding piece (13) which can be moved upwards along a path limited by a stop.
Abstract:
An expansion projectile (1) with a projectile body (2) forms a central arbor (3) at its end face and a collar (4) coaxially surrounding the arbor (3), where the collar (4) has an outer shape (6) tapering towards the free collar edge (5), and between collar (4) and arbor (3) there is provided a cavity (7) open towards the front. In order to achieve a monobloc projectile free from lead with a high efficiency and a wide range of applications in an economic way, the arbor (3) consists of shaft (31) and tip (32) the collar (4) touches the arbor (3) at least in the transition area (33) between shaft (31) and tip (32), and the arbor (3) protrudes at least up to the axial height of the collar edge (5).
Abstract:
In the case of a stator-excited starter-generator, a permanent magnet arrangement, which is magnetized in the opposite direction to the winding excitation, and has yoke overhangs which are radial with respect to the adjacent sector stator elements, is arranged in the axial separating space of two sector stator elements, which are arranged axially one behind the other each stator element is winding-excited by an excitation winding part of opposite polarity.
Abstract:
In a stator-excited synchronous machine with laminated sector stator elements (SS1 or SS2), which are arranged one behind another at an axial distance and are winding-excited by in each case one excitation winding part (EW1 or EW2) of opposite polarity, the operating efficiency can be increased with low outlay when a permanent magnet arrangement (M) having a magnetization opposing the winding excitation in the sector stator elements is provided in the axial spacing chamber between the sector stator elements (SS1 or SS2); in order to lock the position of the magnet arrangement (M), the facing laminations of the magnet arrangement (M) have bent-away tongues (Z) gripping radially from below.
Abstract:
A cartridge is described having a cartridge casing (1) and having a propellant cup (4), which is inserted in the cartridge casing (1), receives a sub-caliber projectile (5) in a formfitting manner, and is manufactured from plastic, and which separates the projectile (5) from the propellant charge in the cartridge casing (1) and has axial separation points (15) along its jacket (10). To ensure an advantageous length for the projectile, it is suggested that the propellant cup (5) have at least one pocket (9), extending in a cavity between the projectile (5) and the cartridge casing (1) and/or in a cavity of the projectile (5) and open toward the base (2) of the cartridge casing (1), for receiving a part of the propellant charge.
Abstract:
A telescopic boom (1) for a vehicle (25) or a hoist with a storage rack (6) for at least two box girders (2, 3) guided displaceably in one another in the direction of their longitudinal axes, which are mounted to pivot about a horizontal pivot axle (5) in the storage rack (6) and which can be displaced reciprocally by means of a servo-drive (19) is described. In order to create advantageous structural conditions it is proposed that the longitudinal axles of the box girders (2, 3) form an upwards arched arc of a circle (4) which runs concentrically to a common axis parallel to the pivot axis (5).

Abstract:
A sub-caliber projectile is described for insertion into a projectile receptacle (8) having a projectile head (1) and a tail unit (2) forming guide vanes (4), which engages in a cavity of the projectile head (1). To provide advantageous construction conditions, it is suggested that the guide vanes (4) of the tail unit (2) extend up into the hollow projectile head (1) and the projectile head (1) be folded clamped into the groin area between the guide vanes (4).

Abstract:
A projectile (1) for a cartridge for hand-held firearms comprises a core (2) and a core jacket (3). The core (2) is made of a material which has a higher specific gravity than the material of the jacket (3). The core (2) and the jacket (3) are positively interconnected.In order to achieve a high penetrating power and a man-stopping effect and to ensure that the trajectory will be relatively short in case of a miss, the core (2) of the projectile is integrally formed on its periphery with deformed portions (6), which extend radially outwardly within a diameter range which is determined by the maximum core diameter and serve to establish a positive joint with the core jacket (3), and in a manner known per se the core jacket (3) is open toward the tip of the projectile.
