Abstract: The invention relates to collapsible fuel tanks for aircraft. 
<??>An aircraft is described with expandable fuel storage tanks 13 on the upper surfaces of the port and starboard wing roots 12. The fuel tanks 13 each have an upper external resiliently flexible surface-defining portion including spanwise-spaced inner and outer edges extending in a generally chordwise direction alongside the fuselage 10 and the wings 11 to which they are attached by sliding joints and hinges respectively. The surface-defining portion may thus move between a "tank empty" position in which it is flush with the surrounding wing surface and "tank full" position in which it lies at an acute angle to the wing surface and forms a fillet between the wing and fuselage.

Abstract: @ The invention relates to a holder for industrial use attachable by vacuum suction. The vacuum is provided by a tube or similar means from a vacuum source to the holder, which comprises a rigid back- piece (3), a flexible intermediate element (2), and a central distance-maintaining element (1). The intermediate element (2) comprises a comparatively rigid sealing ring (9) with a sealing lip (13), which in use abuts against the element held fixed and with its opposite side against the backpiece (3). The central distance-maintaining element (1) is rigidly connected to the backpiece (3), under that the sealing ring (9) of the intermediate element (2) is movably and outwardly resiliently arranged (via resilient means 17). When the side of the sealing ring with the lip is unloaded and the ring is pressed outwardly, vacuum valve means (14) are automatically closed by the. intermediate element, which valve means open when the holder is pressed against the object held fixed whereby the holder is becoming attached by the sucking action.

Abstract: In the production of such articles on extrusion lines from thermoplastic materials containing blowing agent, it is difficult to achieve close dimensional tolerances of the extruded articles and a uniform foam structure. Instead of the previously customary manual variation of the take-off rate, it is proposed to use a - preferably electrically operating - force measuring device to measure the tensile force acting on the extrudate or the die gap compressive force in the calibrating zone. The force-dependent signal of the measuring device is passed to a master controller with adjusting area limitation and compared with the desired force value. The deviation between these two values serves to govern the take-off rate set manually on the drive control of the take-off device.

Abstract: An oscillator comprising a delay circuit having an input terminal and an output terminal, and a tristate inverter having an input connected to the output terminal of the delay circuit and an output connected to the input terminal of the delay circuit. This tristate inverter is adapted to be switched by a control signal between an operable condition and an inoperable condition. A wave shaping inverter is connected to the output of the tristate inverter to generate a shaped pulse signal. Further, there is provided at least one tristate inverter having an input directly connected to an output of the tristate inverter itself so that it can generate a predetermined potential corresponding to the threshold of the tristate inverter itself. This voltage generating tristate inverter is connected at its output terminal to a selected one of the input and output terminals of the delay circuit. This voltage generating tristate inverter is adapted to be put in response to the control signal, when the first tristate inverter is put in the inoperable condition, in such a biasing mode as to generate the above predetermined voltage at the output terminal, and when the first tristate inverter is put in the operable condition, in such a floating mode as to bring its output terminal into a floating condition, so that the first tristate inverter oscillates because of a feedback given by the delay circuit.

Abstract: A video picking and clipping method and apparatus are described. The picking method and apparatus comprise: A CPU and a direct memory access (DMA) circuit which is used with a graphics microprocessor (GµP) for virtually redrawing a display list from a system memory of objects in a bit map. A starting address and a number corresponding to the number of instructions in a segment comprising a plurality of display lists are sent to the DMA for this purpose. When the coordinates of a pointer match the coordinates of a selected data object, a pick interrupt signal and special pick instruction is sent to the CPU. The CPU then uses the starting address of the display list of a selected object from a table to generate a new display list to perform a pre-selected operation on the selected data project. The clipping method and apparatus comprise a plurality of data planes for storing data objects, a match plane for storing a clipping object and a one-bit register. In use, the pixels in the data and match planes are scanned. When a match occurs between a pixel in the match plane and the contents of the one-bit register, a match signal is generated. The match signal enables the data planes to re-store the corresponding pixels of the data objects in the match planes.

Abstract: The invention relates to a set of toothed gearings for multiple gear toothed gearings with increasing output drive torques, consisting of any number of toothed gearings, whose axis separation distances correspond to a mathematical series. The invention is that each second, and possibly each third, gear size corresponds to the preceding gear size up to the diameter of the output gearwheel and hence also to the output gear axis separation. Since, in the case of these gear sizes connected in the series, only the diameter of the output gearwheels and the axis separation of the outputs are greater than in the case of the respective preceding gear, increased output drive torques are possible in each case while maintaining the plurality of gearing internal parts. In this way, finer gear-change ratios of the output drive torques are achieved for the complete series. <IMAGE>

Abstract: In drive pulse circuitry for semiconductor switches (1-4), each having a freewheeling diode (D1-D4) connected in parallel with it, and which are arranged in the arms of a bridge, it is intended to apply a controlled mean current value to a resistive-inductive load (5), with a low power loss, located in the diagonal of the bridge. To this end, two semiconductor switches (e.g. 1, 4), located diagonally opposite one another in the bridge, are switched on in one current-flow phase, while a freewheeling current flows through the load in the subsequent freewheeling phase. To reduce the power loss, at the start of the freewheeling phase only one (1) of the two diagonally opposite semiconductor switches (1, 4) is opened and, subsequently, a semiconductor switch (3) located in the bridge adjacent to the conducting semiconductor switch (4), is switched on. Before the start of an immediately subsequent current-flow phase, the semiconductor switch (3) located in the bridge adjacent to the conducting semiconductor switch (4) is opened, before the opened semiconductor switch (1) of the two diagonally opposite semiconductor switches (1, 4) is closed again. …<IMAGE>…
