Abstract: 1276250 Matrix displays LICENTIA PATENT-VERWALTUNGS GmbH 14 May 1970 [16 July 1969] 23333/70 Heading G5C [Also in Division C4] A display arrangement comprises a crossed array of conductors l x , l y , a light source C L  and a photosensitive resistance R F , receiving light from the source connected in series across each intersection, means U B  for applying to any pair of intersecting conductors a voltage which is sufficient to cause the associated source to emit visible light when the resistance is illuminated by the source but insufficient if it is not illuminated, means U A  for temporarily applying a voltage across a source to cause it to emit and decoupling means D for preventing the illumination of one resistance resulting in other sources emitting light. Without the means D when e.g. resistance R F11  is illuminated sources C L21 , C L22  and C L12 , each receive U B1,  3  which is sufficient to cause them to emit light. Crossed conductors l x1 , l y1  are selected by switches S x , S y  and an associated switch S L1  is closed to apply voltage U A  to source C L11 , this illuminates the adjacent resistance R F11  reducing its resistance so that on removing U A  voltage U B  is sufficient to maintain source C L11 . The decoupling means D may comprise a diode, resistance or condenser mounted with the resistance R F  on the source comprising a semi-conductor element or an incandescent lamp. The switches may be manually, semi- or fully-automatically controlled or be replaced by means applying voltage pulses. The conductors may form concentric arcs and radii, the sources may form a threedimensional array. A coloured display may be provided by replacing each source by four electroluminescent elements emitting different colours mounted in a rectangular box whose sides form electrodes and whose ends are open to permit viewing. To extinguish a source the location of ignited sources is determined by measuring the voltage at test points P x , P y . This information is fed to a storage unit, information relating to a source to be extinguished is cancelled and the remaining information used to relight the desired sources.

Filed: 1928-08-14
Abstract: 321,470. Linotype & Machinery, Ltd., and Newton, S. Aug. 14, 1928. Inking-apparatus. -In an intaglio printing- machine, the ink is supplied to the printing- surface during each normal operative cycle of the machine by moving the ink trough so that the printing-surface is immersed in and moves through the ink contained in the trough. The trough containing the ink 3 is constituted by the doctor 4, a movable floor 5, and side walls 6. The floor 5 is secured to a bar 8 movable in slots 9 in the walls 6, the slots being parallel to the doctor 4 so that the floor is kept in ink-tight contact therewith throughout its movements. The bar 8 is carried by slidable rods 10 adapted to be operated by a cam 13 on the shaft of the printing- cylinder 1 so as to depress the floor 5 during the passage past the trough of the gap 2 between the ends of the printing plate. Springs 14 on the rods 10 return the floor 5 to its normal position. The walls 6 are secured to a shaft 29 angularly adjustable by a worm 32 and worm-wheel 30 in arms 15 pivoted about a shaft 16, and the arms may be reciprocated axially of the shaft 16 in any suitable manner to impart a reciprocating movement to the doctor 4. Fine adjustment of the doctor can be effected by screws 35, carrying the doctor by means of a support 33, and threaded through nuts 36. In a two-revolution machine, means may be provided to move the trough into an inoperative position during alternate revolutions of the cylinder 1. For this purpose the arms 15 rest on cams 17 on a shaft 18 which, by gearing 19, 20 and a cam 23 on a shaft 24 driven at half the speed of the cylinder 1, receives a rocking movement whereby the cams 17 allow the arms 15 to fall to carry the trough into an inoperative position. To prevent flow of the ink over the edge of the doctor 4 in this position of the trough, the floor 5 is depressed by arms 28 engaging the rods 10 and operated from the cam 23. Ink is continually supplied to the trough by a pump 37, surplus ink overflowing through pipes 7 and returning by way of a tray 40, pan 41, and channel 42 to the pump 37.

Filed: 1972-05-19
Abstract: 1395917 Rectifying LICENTIA PATENT-VERWALTUNGS GmbH 19 May 1972 [21 May 1971 7 July 1971 8 Oct 1971] 23729/72 Heading H2F A method of controlling a rectifier with controllable rectifiers and quenching devices associated therewith comprises quenching a controllable rectifier during a half cycle and retriggering it after a current-free pause, said quenching and re-triggering occurring only once during each half cycle. The controllable rectifier may be a thyristor in a single or threephase bridge of thyristors (or thyristors and diodes) and may provide power for a D.C. motor 15. As shown in Fig. 11, the secondary 5 of a single-phase transformer having leakage inductance 18 feeds a bridge of diodes 1, 2 and thyristors 3, 4, the latter being quenched at α 1  by turning on thyristors 8, 9 so as to discharge commutating capacitors 6, 7 through the conducting thyristors 3, 4. The commutating capactiros 6, 7 are previously charged via diodes 12, 13. The Specification explains the effect of various saturable inductors in the circuit. The quenching and re-triggering improves the power factor of the circuit which may thus be capacitive. Fig. 23 shows a series pair of such bridges having a single commutating arrangement 6, 10, 8, 9. Thyristors 21, 22 are provided for initially charging commutating capacitor 6. Freewheeling current can pass via diodes 1, 2 or via a thyristor connected for that purpose. Fig. 15 shows a bridge of diodes 1, 2 and thyristors 3, 4; further thyristors 23, 24 being connected to a tapping on the input secondary 5. Thyristors 3, 4 are turned on at the beginning of a half cycle and turned off by quenching thythyristors 8, 9; thyristors 23, 24 being simultaneously turned on so as to complete the remainder of the half cycle at a lower voltage. Modifications.-In Fig. 20 (not shown) two pairs of commutating thyristors are connected in parallel via respective fuses. In Fig. 13 and 21 (not shown) anti-parallel quenching thyristors are connected in series with a commutating capacitor across winding 5. Figs. 26, 27 (not shown) relates to three-phase circuits.
