Title: Control system for a telecommunications network
IPC: H04Q9/00
Filed: 1970-10-09
Abstract: 1333038 Automatic exchanger SOC ITALIANA TELECOMMUNICAZIONI SIEMENS SpA 9 Oct 1970 [9 Oct 1969] 48161/70 Headings H4K and H4P A control system for a telecommunications network samples multi-channel supervisory lines and forwards telegraphic supervisory messages to a multiplex receiver, the passage of messages being inhibited on stepping on to the next channel to be sampled, receipt of an end of message signal from the receiver or when a fault condition is detected on a sampled channel, and the stepping to the next channel to be sampled being made on stepping to a channel which is not connected to any supervisory unit, an end of message signal from the receiver or when a fault condition is detected. In Fig. 3 supervisory frequency-shift channels C 1 -C 6  on each of lines L 1 -L 6  are connected to the output line M<SP>1</SP>, M by selector SLC controlling line gates AL by marking leads L<SP>1</SP> 1 -L<SP>1</SP> 6  and channel gates DC by marking leads C<SP>1</SP> 1 -C<SP>1</SP> 6 . A matrix PD indicates which channels of each line are actually connected to a supervisory unit and therefore can expect to contain supervisory data. Upon selection of a particular line and channel carrying data by unit SLC, one of NAND gates N 1 -N 6  is closed, causing one or the other of monostable flip-flops M 1 , M 2 , depending on whether an even or odd numbered line is selected, to change providing a signal C to close NAND gate N14 and pass the supervisory message to output line M. An end of message signal S, received from the multiplex receiver, not shown, resets bi-stable B 6  thereby opening NAND gate N 12  at the next clock pulse H to step on the selector SLC. If a selected channel carries no message all NAND gates N 1 -N 6  remain closed and NAND gate N 12 , normally closed by a beginning of message signal S setting B 6 , remains open to pass clock pulse H to immediately reset selector SLC. A fault condition is assumed if a message contains 24 consecutive ones or zeros allowing counter B 1 -B 5  to count 24 clock pulses H and provide a stepping signal to selector SLC via gate N 16 . An unfaulty message contains sufficient 0-1 or 1-0 transitions which by setting and resetting bi-stables N 5  and M 6  provide sufficient resetting pulses via gate N 1 5 to prevent a count of 24 being reached.

Abstract: 1,033,947. Automatic devices for uncoupling railway vehicles. STAMICARBON N.V. Dec. 10, 1963 [Dec. 12, 1962], No. 48806/63. Heading B7T.  Apparatus for automatically uncoupling hook- and-link railway couplings comprises, at an uncoupler station along the rail track 1, a carriage 3 which may be reciprocated alongside the track on guides 2 and is provided with a structure 4 which may be moved at twice the speed of the carriage 3 and supports an arm 6 which by means of a piston 18 is transversely extensible between trucks advancing to be uncoupled, the arm during its extension pushing the vehicles a limited distance apart so that an uncoupler 8 (e.g. magnetic or mechanical) may be lowered between the vehicles by a piston 19. The carriage 3 supports pulleys 11 around which a rope or chain is taken and fixed to the relatively movable structure 4 and a fixed post 13. In operation, movement of the carriage 3 is brought about by a piston 10 and the pulleys 11 and their rope ensure that the structure 4 moves faster than the carriage and the speed of the structure 4 is synchronized to that of the truck so that the arm 6 may be extended to push between the tracks using spaced wedging members 7 and 9. By using two wedges the angle of each of the wedge members may be reduced, and the member 9 may be inserted between the buffers of two trucks in line. Thus the trucks are pushed apart to allow the uncoupler to be lowered therebetween but the space between the trucks is limited by, for example, arranging the leading truck to uncouple on rising portion of track 1 so that the trucks tend to buff together on the wedges 7, 9. The carriage 3 is provided with a pulley 14 over which power lines and tubes are run to bridge the charging distance between the fixed points 15 connected to a power panel and a mast 17. Control devices such as 20 and 21 are provided, and the pillar 5 may be trip-hinged to swing out of the way should a truck bump the extended arm 6. The trucks may be advanced by mechanism as described with reference to Fig. 10 of Specification 926,439, and displacement of the structure 4 may be initiated by the trucks operating pedal valves as in Fig. 14 of the above Specification.

Abstract: 1,005,273. Lamps. EDNALITE CORPORATION. Dec. 11, 1963, No. 48842/63. Heading F4R. [Also in Division G2] A light table for illuminating transparent or like objects comprises a circular plate 22 of translucent light dispersing material, a concentric circular light tube 19 spaced from and parallel to the plate, and a reflecting surface 12, 25 extending from the periphery of the plate and enveloping the tube, the reflecting surface being in the form of a surface of revolution generated by the rotation about the axis Z-Z of a generatrix including an outer part P 1 -P 4  conforming substantially to the arc of an ellipse 30 and an inner part P 4 -P 9  extending from the arc to the axis Z-Z and comprising an arc P 8 -P 9  of reversed or opposite curvature to that of the outer part, the central portion of the surface being a mound 31 directed towards the plate 22. The ellipse 30 has its major axis extending radially from the axis Z-Z and its outer focus F 1  located at the centre of the section of the light tube 19. Between the points P 2  and P 3  the outer part of the generatix deviates from the elliptic arc along lines which converge on the central plane of the light tube either outside (Fig. 3) or inside (Fig. 5) the ellipse, so that light which would otherwise be reflected back into the tube is caused to by-pass the tube and is therefore available to illuminate the plate. The construction of the reflecting surface is such that the light table compensates for the " vignetism " of photographic objective lenses, which produce an image the intensity of illumination E of any point of which is equal to the intensity of illumination E 0  of the corresponding point on the object multiplied by the fourth power of the cosine of the angle u between the optical axis and the point on the object. If a photographic negative placed on the table is to have a uniformly bright image, then to compensate for the law E = E 0  cos<SP>4</SP> u the illumination of the table must obey the E c  = E r  COS<SP>4</SP> u where E c  is the intensity of illumination at the optical axis Z-Z and E r  is the intensity of illumination at any point at the angular distance u from the axis. The Specification tabulates measurements relating to three light tables having plate diameters of 6, 9¢ and 13¢ inches, respectively, which show that the invention provides intensities of illumination differing by only small amounts from the theoretically desired values. The part 12 of the reflecting surface preferably comprises the upper part of the housing of the device, the part 25 of the surface being a circular reflector. A lower housing part (not shown) contains the control equipment for the tube 19. Stepped support means (not shown) for illumination filters, glass slides and the like may be secured to the upper part of the housing at intervals around the periphery of the plate 22.

Abstract: Crystallized aescin or primulic acid are subjected to shearing forces in a grinding apparatus for a time sufficient to destroy the crystal structure and to convert the saponin to an X-ray amorphous state of increased water solubility. The saponins are ground in an agate or hard porcelain mortar.  The required shearing forces are not normally obtained in a ball or jet mill, but necessitate grinding in a mortar or mortarmill, or in a roll mill in which the rolls are rotated at different speeds.  The crystallized aescin or primulic acid may be mixed with a flavonoid glucoside such as hesperidin and then subjected to the above shearing forces to form a complex with the aescin or primulic acid.ALSO:A therapeutically valuable saponin preparation containing aescin or primulic acid having an X-ray amorphous state of increased water solubility is prepared by subjecting crystallised aescin or primulic acid to shearing forces for a time sufficient to destroy the crystal structure.
