Abstract: The two parts (10, 11) of the box hinge are connected releasably to one another, that is to say the hinge pin (16) of one part (10) and the hollow cylinder (17) of the other part (11) can be disengaged by axial displacement. Furthermore, the hinge pin (16) is mounted on the associated hinge part (10) so as to be rotatable and axially displaceable and is resiliently prestressed axially. At its free end, it is equipped with a rotation prevention means (38) which is engaged with the other hinge part (11) fixedly in terms of rotation and axially releasably. During the opening and closing of the particular box, the hinge pin (16) thus positively executes a rotational movement. In its portion located on the same side as the bearing, the hinge pin (16) is equipped with a radial grooved dowel pin (24) which at a predetermined angle engages as a result of spring force into a bearing notch (22) and thus locks the two hinge parts (10, 11) releasably at a predetermined opening angle.

Title: Method for the production of pressure vessels
Inventor: HOFFMANN BERNHARD DIPL ING
IPC: B21D51/24
Filed: 1988-12-23
Abstract: The invention relates to a method for the production of cylindrical pressure vessels, the steel tube used having a particular composition. In order to achieve economical production of the pressure vessel without compromising component safety, it is proposed that the steel tube used should be produced from hot wide strip rolled under normalising conditions, that the degree of deformation during the hot forming of the ends of the tube by the spinning method should, depending on the local temperature, be set sufficiently high to give a fine-grained structure and that the pressure vessel produced should not subsequently be subjected to any further heat treatment.

Title: Digital circuit for bit pattern recognition
Inventor: IMHOFF JORG
IPC: G06F7/02
Filed: 1989-02-28
Abstract: Pattern recognition requires a large number of bit pattern comparisons. The described circuit makes it possible to carry these out simultaneously in a very short time. The circuit consists of identical, mutually independent subsystems (see drawing), each of which stores one bit pattern. Each subsystem tests the input bit pattern to be investigated bit by bit for equality to the stored bit pattern (A), and stores the result in a memory (C). The more similar the compared bit patterns were, the closer this is to the pattern 111 ... 11. The outputs of the memories are randomly wired to a C times number (e.g. C = 3) of contact points, of which C contact points are then combined into a group (D) in each case. Each group is tested for a majority of 1 or 0 bits, and a corresponding result bit (1 or 0) is generated (E). These result bits are fed back to the memory, and stored with each clock signal (C). If the memory contains more 1 bits than 0 bits at the start, its content develops with each clock signal to the bit pattern 111 ... 11, and if not, to the bit pattern 000 ... 00. If 111 ... 11 is reached, the subsystem outputs an output signal (F). The more similar the input bit pattern and the bit pattern which was stored in the subsystem at the start were, the faster the output signal is generated. The time sequence of the output signals of the subsystems arranges the stored patterns according to their similarity with the investigated ... Original abstract incomplete. <IMAGE>
