Title: Apparatus for the transport of bobbins
Inventor: GMOEHLING WALTER
IPC: B65H49/38
Filed: 1987-07-28
Abstract: There is an apparatus, in which there are provided rods 3 which are suitable in length for receiving a plurality of bobbins 10 and which are equipped with an abutment 7 for supporting the lower bobbins 10. It is desirable, at the same time, if, whilst preserving a simple loading and unloading capacity, the rod length can also be designed in a simplified way for a quadratic vertical cross-section of the apparatus. This is achieved in that the rods 3 are mounted vertically on a horizontal basic frame 1, the abutment 7 is guided 8 on the respective rod 3 so as to be longitudinally displaceable, and each rod 3 is assigned a spring 6 which can be tensioned and relaxed in a load-dependent manner and which engages on the abutment 7. Since the rods are assigned load-dependent springs, all the bobbins can be loaded and unloaded at the top ends of the rods. <IMAGE>

Patent DE-3817407-A1 (DE)
Inventor: BLEICHRODT MANFRED DIPL ING
IPC: H04L12/28
Filed: 1988-05-21
Abstract: On a serial bus configured in ring structure, to which several series-connected transmitting and receiving stations and a central ring control are connected, the possibility is to be provided to switch through information items of more than two different switching categories on the same transmission medium. In this connection, so-called broadband channels are formed which can either be reserved for a connection-related or line-related synchronous channel allocation or are made available for the asynchronous switching of data packaged in variable-length packets. Given these prerequisites, the possibility is to be provided to switch through packets of a third switching category. The information of the third switching category, packaged in packets of uniform length is also asynchronously switched through in that some of the broadband channels reserved for the synchronous type of switching through but not yet used are occupied for this purpose. In this connection, all stations transmitting and receiving the third switching category are informed by transmitting signalling data as to the broadband channels in which information items of this third switching category can be transmitted and received. The transmissions of the information items packaged in packets of uniform length in accordance with the scheme of the third switching category over the same transmission medium are made possible without having to carry out modifications in a standard defined for the mixed transmission of synchronous and asynchronous information items. <IMAGE>

Title: Projectile with no yaw angle
Inventor: WIEMER PETER DIPL PHYS DR
IPC: F41G7/00
Filed: 1988-08-05
Abstract: In the case of a fin-stabilized projectile (1) of a weapon for attaching a tank (2) from above, the target terminal flight phase is initiated by a force on the missile nose, in particular on the control unit (4) which is located there. Since the control unit (4) rotates because of a target-detecting sensor, this rotary movement produces oscillatory movements of the projectile because of the gyro affect, and thus target offsets at different combat ranges. In order to avoid this yaw angle being produced in the rotating sinking phase and in order to avoid lateral offsets of the projectile, means are provided within the projectile (1), between the control unit (4) and a warhead (3), which means give the warhead (3) a rotational momentum which corresponds to the rotational momentum of the control unit (4) but acts in the opposite direction to it. These means are designed in such a manner that they are at the same time also suitable for use as drive means for producing the rotation of the control unit (4). According to one possible exemplary embodiment, gases, which emerge tangentially from nozzle in the warhead (3), from a pyrotechnic drive cause an enveloping impeller wheel, which is connected to the control unit (4), to rotate in the opposite direction. The invention also discloses the use of mechanical drive means, such as the use of a spiral spring or of a helix, for example, to achieve the same affect. <IMAGE>

Title: Vertical transistor arrangement
Inventor: FAUL ROBERT DIPL ING
IPC: H01L27/092
Filed: 1988-11-11
Abstract: The invention relates to a vertical transistor arrangement which, starting from a semiconductor substrate (5, 40) is built up from a vertical layer sequence (9, 15, 16; 46, 47, 48) made from semiconductor material of different conduction type. The gate electrode (4, 36, 37) is arranged in a trench reaching at least over the channel zone of the transistor and insulated electrically with respect to the semiconductor layers. Furthermore, connections are provided for the gate electrode and the sink and source regions. When a transistor is switched through a main current flows vertically through the semiconductor layers. In order to be able to make versatile use of such a vertical transistor arrangement, and to be able to build up integrated circuits therefrom on a semiconductor chip, the invention proposes that a transistor (2, 3; 32, 33, 34, 35) is built up respectively on both sides of the trench (17) for the gate electrode (4, 36, 37), resulting in a double transistor made from two transistors (2, 3; 32, 33, 34, 35), and that on the semiconductor substrate (5, 40) there is applied an insulation layer (6, 43) which reaches as far as the trench (17) for the gate electrode (4, 36, 37) at least on one side and thereby electrically isolates the two transistors (2, 3; 32, 33, 34, 35) from one another.   <IMAGE>
