Title: Mast, which can be elevated, for a combat vehicle
Inventor: GLUECK WOLFGANG
IPC: H04B10/00
Filed: 1986-08-02
Abstract: A cable consisting of at least two optical fibres is laid within or along the mast which carries the combat platform for bidirectional signal transmission between a combat vehicle and said combat platform, which can be elevated out of the combat vehicle. The analogue electrical signal which is to be transmitted is digitally coded and is subsequently electrooptically converted. Before coding, the data format of the digitised electrical signal can be matched to existing data formats used for signal processing in the combat vehicle, for example to the MIL-Bus system. The optical coupling points of the optical fibres are supported in a vibration-damped manner in order to prevent them coming out of adjustment. The use of optical fibres makes it impossible for the transmission cable to act as an antenna, and thus makes scattering and emission of electromagnetic waves impossible. <IMAGE>

Title: Pressure-medium cylinder with rolling seals
Inventor: NEUHAUS HERMANN ING GRAD
IPC: F16J3/06
Filed: 1986-09-26
Abstract: Pressure-medium cylinder with rolling seals which are provided with transverse grooves for fibre length compensation and are made of metallic spring materials and also have a sliding bush for the static compensation of two rolling diaphragms. Since the rolling seals of the application are not made of elastomeric spring materials but of metallic spring materials, the peripheral lengths of the outer gap and the inner gap which enclose a rolling seal, such as, for example, the periphery of the cylinder inner wall or the undulating periphery of the piston, must be the same size. Furthermore, the rolling seals must be constructed in such a way that, upon transfer of the outer leg to the inner leg position, the theoretical fibre lengths must be present in the rotation form. The problem was solved firstly by the circumferential surface of the piston being of undulating design and by the undulation length being equal to the peripheral length of the cylinder inner wall; secondly by the diaphragm foil of a rolling seal being provided over the entire periphery with transverse grooves which permit fibre length compensation and furthermore by the outer gap surfaces of the pressure-medium cylinder likewise being provided with transverse grooves; and thirdly by a sliding bush being used for the static compensation of two rolling seals.

Title: Elongated luminaire
Inventor: FRITZ HEINZ-DIETER
IPC: F21V5/02
Filed: 1986-12-18
Abstract: In the renovation of old illuminating systems for office rooms by means of BAP luminaires, because of the prescribed dimensions of the ceiling apertures accommodating the luminaires, for example, use can be made only of luminaires in which the ratio of the width (b) of the exit aperture, in terms of lighting engineering to the height (h) of the lamp cannot be selected above the plane of the optical aperture to be so small that given an emission angle of  gamma  > 50@ in the CO-180 plane the luminaire is limited in accordance with the BAP condition to </= 200 cd/m<2>. In order to provide a remedy here, it is proposed to provide respectively on either side of the lamp (3) below the lamp (3) and above the mirror screen (4) inserted into the optical aperture of the luminaire a strip-shaped optical guiding element (6, 7, 8, 11, 12) by means of which the direct emission of the lamp light is suppressed in the case of an emission angle of  gamma  > 50@. <IMAGE>
Patent DE-3700103-A1 (DE)
Title: Device for saving energy in oil/gas boilers
Inventor: DE MEULENAER HUBERT
IPC: F24D12/02
Filed: 1987-01-03
Abstract: This device consists of a copper spiral which is built into the waste-gas pipe and of a direction pump, the latter being linked to the heating flow pipe and being in connection with the copper spiral, the end of which is connected to the heating return pipe, in such a way that a circuit starting from the flow pipe, to the pump, via the copper spiral, to the return is produced. Since boilers are generally situated only 50 cm away from the corresponding chimney, only the surface of this waste-gas pipe thus remains for utilisation of the waste-gas energy. By installing a copper spiral, however, the surface can be approximately doubled in comparison with the waste-gas pipe. Virtually the same value has been obtained in practice in this connection.

IPC: B63B43/26
Filed: 1987-04-24
Abstract: The invention concerns a bulkhead for ships, in particular ro-ro ferries, for water-tight subdivision of a compartment at the position of a specified, and in particular essentially rectangular, cross-section. The bulkhead has two parallel plates (8, 9) positioned next to one another and arranged to be movable horizontally in their plane so that they overlap in a first position (A) and a second (B) position at the one side of the cross-section or the other. In a third position (C), one plate (8, 9) abuts on each opposite side of the cross-section, so that the cross-section is closed off. The gaps between the plates and the gaps at the edge of the plates (8, 9) are sealed by sealing means. In this way, a bulkhead is created that does not create much of a hindrance in loading and unloading the ship. <IMAGE>

Title: Device for regulating the ground-parallel boom position on plant-protection machines
Inventor: KAUL PETER DR ING
IPC: A01M7/00
Filed: 1987-07-10
Abstract: Device for regulating the ground-parallel position of plant-protection and fertilising machine booms having working widths of more than 10 m, by means of which both changes in the location on a slope and unevenness of the ground between the travelling tracks are compensated sufficiently quickly and therefore parallelism is maintained virtually continuously, a good distribution quality is ensured and the risk of boom breaks as a result of contact with the ground is avoided. This object is achieved, according to the invention, in that, with the vibrational systems completely uncoupled in the vertical and horizontal direction, a cascade control is built up, the "rapid" follow-up controller combating the influence of the higher-frequency ground unevenness by a utilisation of the gravitational force, and without auxiliary energy, by an I-behaviour. The slower master controller counteracts low-frequency disturbances as a result of variations in the gradient of the slope by a PI-behaviour and auxiliary energy. The regulating system can be supplemented by a further regulating system for adapting the boom to a varied ground micro-profile.
