Patent ES-298320-A1 (ES)
Title: Jacquard machine with an open shed carrying hook needles, providing a double positive action
IPC: D03C3/06
Filed: 1964-04-04
Abstract: A double lift open shed jacquard has main needles A having downturned ends D situated between two sets of presser bars P, T which reciprocate in unison. Each main needle has a pair of projections engageable with the outer sides of the legs of a two-legged hook C so that when the associated reading needle G drops into a hole in the pattern card, the end D of the main needle remains in the path of presser bars P, T and is moved to the right (on odd-numbered picks) or to the left (on even-numbered picks), thereby flexing the left or right leg of the hook into the path of the griffe M1 or M2 which is rising at that time. As shown at C3, when a hook is lifted by a griffe, continued pressure by the main needle when the hook has reached its top position causes the hook to swing about its point of suspension on the griffe so that an outwardly-facing nose at its lower end comes to rest on a fixed locking bar R to retain the hook in the open shed position. When the reading needle G subsequently encounters a blank on a pattern card and therefore lifts the end D of the main needle clear of the presser bars P, T, the next griffe to rise engages the hook at the top of its stroke and lifts it slightly to disengage ,it from the locking bar R, whereupon the hook resumes its vertical attitude and can pass down between the bars R. To enable the griffes to engage the hooks in these circumstances even though neither leg is being flexed by the main needle, fixed deflectors V are provided to squeeze the legs inwards at the top of their travel. The fixed locking bars R and the co-operating noses on the hooks may be omitted if a movable locking grid is provided to hold the hooks in the open shed position by engaging their top noses. Instead of the top noses being inwardly directed as shown, they may be outwardly directed, in which case the ends D of the main needles are turned upwards.

Title: Convergence apparatus for nullifying unwanted induced deflection currents
IPC: H04N9/28
Filed: 1967-02-11
Abstract: A convergence control circuit for a multibeam colour reproducing cathode-ray display tube includes means for nullifying unwanted currents induced in the convergence means from the beam deflection means. Such currents produce adverse effects at the vertical deflection frequency, mainly in the blue-gun convergence means and the described embodiment is directed to the correction of such effects. Thus, as shown in Fig. 3, the vertical winding 34B of the blue convergence magnet 32, which is supplied with a voltage wave 45b, generally of parabolic shape and derived via a shaping circuit 44 from the wave 42 produced across cathode resistor 39 of the vertical output tube 35, to effect the normal convergence correction, is further supplied via potentiometer 59 with opposite polarity pulse type voltage waveforms 50, 51 derived from the vertical output transformer 37. These waveforms are modified by the shunt arrangement of diode 61, which may be replaced by a capacitor (Fig. 13, not shown) and resistor 62, as explained with reference to equivalent circuits (Figs. 4 and 5, not shown) and voltage waveforms (Figs. 6a to 9, not shown) to produce a resultant voltage waveform having the shape shown in Fig. 10. This produces a current waveform in winding 34B having the shape shown in Fig. 12 which opposes the current waveform (Fig. 11) induced by the beam deflection means due to the proximity of the latter to the convergence windings on the neck portion of the display tube (Fig. 1, not shown). The vertical windings 34G and 34R of the red and green convergence magnets are supplied with the parabolic voltage waveform 45 and tilt control is effected by means of a master tilt control potentiometer 48 which introduces a saw-tooth current wave 52 as a result of application of the voltage waveforms 50, 51. Differential tilt control is effected by potentiometer 56 and a differential amplitude control potentiometer 53 varies the distribution of the parabolic current through the windings 34G, 34R. The circuitry for the horizontal convergence winding 33G, 33R, 33B may be of known type.

Title: Method and a device for purifying the exhaust gases from motor-driven mining trucks
IPC: F01N3/021
Filed: 1967-05-24
Abstract: In a mine truck, which may be articulated and which has a container 4 for ore and a pair of engines 3, each with its own catalyst filter 5, the exhaust ducts 6 are led to a common pipe 7 and through a connection 13 to a duct system 8 in the container 4 so that the exhaust gases percolate through and are purified by the load in the container. The connecting device 13 comprises a curved section 10 rotatably mounted with respect to the pipe 7 on a pivot 11, and having a ball connection 16, 17 to a pair of telescoping tubes 14, 15 urged apart by a compression spring 21 and which also have a ball connection 19, 20 with the duct system 8. A compression spring 22 exerts an upward bias on the connection 19, 20, the part 19 of which has a guide member 25 engaging a guide rail 28 so that when the load container 4 moves upwardly, e.g. when discharging its load, the members 19 and 20 are separated, the member 19 being located by engagement of the guide member 25 with a recess 30 in the rail 28 to facilitate re-engagement of the parts when the container returns to its transport position. A fin 18 restricts movement of the ball point 16, 17 in a vertical plane.
