Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to a device for transporting in print-ing machines, especially in teleprinters, paper which is perforated along two opposite edges.  The plates of the printing machine is provided at both ends with apertures distributed around its circumference, at a spacing corresponding to the spacing of the perforations of the paper.  Within the platen and at each end is a pin wheel rotatably and eccentrically disposed so that at any given time only some of the pins of each pin wheel extend through the apertures in the platen and into the perforations of the paper.  Since the pins only project over only a limited region of the platen, they present less obstruction in the machine, and insertion of the paper is simplified.

Abstract: 1  oF 2 La divulgation décrit une cisaille circulaire pour découpage multiple continu à chaud de barres métalliques de section rectangulaire ou carrée, en cascade avec les matériaux provenants d'une coulée continue en aciérie et/ou bien d'un blooming. Cette cisaille comporte essentiellement deux ensembles mécaniques dont les fonctions sont complémentaires.  Le premier comprend deux cylindres découpage mécanisés et actionnés par un moteur, qui présente deux cannelures de largeur égale à la largeur des barres à découper et de profondeur inférieure à la hauteur de ces barres mêmes.  Ces deux cylindres sont superposés de sorte que à chaque cannelure correspond, en accouplement géométrique, une partie non cannelée de l'autre cylindre.  Le nombre total des cannelures du cylindre supérieur et du cylindre inférieur est égal au nombre des barres découpées. Les cylindres peuvent être réalisés en une seule pièce ou bien en plusieurs  pièces assemblées pour obtenir le profil susmentionné. Le deuxième ensemble comprend, par rapport au nombre des barres découpées, un ou plusieurs outils inférieurs et un ou plusieurs outils supérieurs façonnés au préalable et par rapport à la dimension de la section des barres, et accrochés au robuste bâti de la machine, ayant, par rapport à l'emplacement inférieur ou supérieur, fonction de guide, de support, de poussée latérale, d'écartement, avec l'addition de détails (21") destinés à racler et à émousser selon l'exigence du travail.

Abstract: ABSTRACT             The longitudinal slippage or creep or a mine conveyor is monitored optically with a view to saving production.  The method involves transmitting an optical signal from a primary source in the mine roadway to a reflector on the conveyor and receiving the reflected signal with a receiver adjacent to the primary source and reducing the angular movement of the re-flector  and line creep of the conveyor.  An optical method is used to calculate the distance between the primary source and conveyor by measuring the time taken for a light signal to travel from the source to the reflector and back again.  Alternatively or additionally, cord transducer is used to measure the distance. Processing circuitry calculates the conveyor creep from the angle and distance measurements. The invention provides apparatus for carrying out the above method.

The output of the zirconia sensor is sampled at constant fre-quency sampling intervals and an up/down counter is set in one of its counting modes as a function of whether the air/fuel ratio is less than or greater than the stoichiometric ratio. During each sampling interval, a first number of clock pulses from a clock pulse generator are coupled to the up/down counter when the air/fuel ratio is greater than a stoichiometric ratio and a second number of the clock pulses are coupled to the up/down counter when the air/fuel ratio is less than the stoi-chiometric ratio.  The air/fuel ratio of the fuel mixture sup-plied to the internal combustion engine is varied in accord with the net count in the up/down counter so that the average air/ fuel ratio is offset from the stoichiometric air/fuel ratio by a value determined by the difference in the first and second numbers of clock pulses supplied to the up/down counter.

Abstract: OBJECT DEFLECTION SENSOR    Abstract of the Disclosure An ink drop height sensing device for an ink jet recording apparatus, the apparatus including a nozzle for forming and propelling a stream of ink drops towards a recording media in a predetermined deflection plane.  A light source on one side of the intended path or trajectory in the plane of deflection of the ink drops impinges upon a mask located on the opposite side of the plane, which mask is aligned with a light sensitive device such as a phototransistor located behind the mask.  The mask includes first, second and third line sensors, in the illustrated instance serially arranged slots with at least two of the slots being in parallel relation, the third slot being inclined with respect to the parallel slots and positioned with respect to them so that at a predetermined point along its length, it is a predetermined distance from the next adjacent slot relative to the distance between the two parallel slots.  The phototransistor is coupled to a timer for comparing the time intervals for the passage of the ink drop between the parallel slots which is compared with the time taken for passage between one of the parallel slots and the inclined slot.  If the time of the drop travel between the parallel slots is determined, (the distance being fixed), and the time of drop travel between one of the parallel slots and the inclined slot is compared to that time interval, dependent upon whether the time measurement is longer or shorter, then it may be determined whether the drop is high or low in the deflection plane and suitable correction may be employed to bring the deflected ink drops to their predetermined deflection height or trajectory path.
