Filed: 1989-08-22
Abstract: A locking plunger (11) which is perpendicular movable relative to the direction of movement of the firing pin (7) allows or prevents the axial movement of the firing pin to fire the gun. This locking plunger (11) is spring (12) biassed to abut a safety lever (14) which is part of the sear (5) of the operating members of the gun. The safety lever (14) is located and arranged such on the sear (5) that it allows a movement of the locking plunger (11) into the firing pin unlocking position upon the operating members of the gun reaching the end of the trigger slack. Accordingly, a movement of the locking plunger into the unlocking position will proceed not earlier than the sear snapping into the firing position. Any other accidental limited movements of the operating parts of the gun including such of the hammer cannot cause an axial movement of the firing pin because such movmement is positively prevented by the locking plunger. Therefore, an accidental firing of the gun is positively prevented.

Abstract: In an imaging apparatus, bipolar clock pulses are supplied from a clock source (4) to the odd- and even-number second shift registers of a linear charge transfer device (1). A voltage representing the difference between offset voltages generated respectively by the shift regtisters is generated by a band-pass filter (11) or a differential circuit (19-22) and multiplied by a multiplier (13) with the bipolar clock pulses to produce a varying-­amplitude voltage of a particular polarity determined by the relative value of the offset voltages (V₁, V₂). The varying-amplitude voltage is smoothed by a low-pass filter (14) into a DC voltage. The DC voltage of appropriate polarity is combined with one of the output signals of the shift registers by a combining circuit (7, 8, 15-18) so that the difference between the offset voltages substantially reduces to zero.

Abstract: This invention relates to a process for producing active carbonyl compounds predominating in aldehyde groups from polybutens having at least 50% of the unsaturation in the terminal position. The process has an initial epoxidation of the polybutene followed by isomerisation of the epoxide so formed at a relatively higher temperature. 
     The active nature of the carbonyl group enables these compounds to be readily converted to the corresponding amines or imines which are useful fuel and lube oil additives.

Abstract: There is disposed a conductive substrate (2) which is connected to a lead (5) at one of the ends of a thin insulating pipe (1), is inscribed with the thin pipe (1) and has a sectional area of up to 10 -5  cm z , ,and a coating film (7) is disposed at the other open  l end of the thin pipe (1) by electrolytic polymerization, thereby forming a film-coated sensor. In the resulting film-coated sensor, the surface is uniform and film formation can be controlled easily. Since the sensor is hardly susceptible to fluidization of a sample liquid, drift is small and response is high. Since the sensor is very small, it can be used for the measurement of a minute sample or can be directly inserted into a living body or into a tissue for measurement. When covered with immobilized enzyme, the film-coated sensor can be used as an oxygen sensor.

Abstract: Pour la fabrication de matériaux de contacts au CuCr, on emploie fréquemment des procédés faisant appel uniquement à la métallurgie des poudres ou des procédés par frittage et infiltration. Le but recherché est d'obtenir une porosité résiduelle minimale, qui doit être inférieure à 1 %. Dans l'invention, la densification du comprimé à partir des composants est effectuée en deux étapes, dont la première est un frittage avec une densification jusqu'à l'obtention d'une porosité fermée du composé fritté et la deuxième un procédé de compression isostatique à température élevée, dans lequel les pièces non enrobées sont portées à une masse volumique finale représentant une densité relative d'au moins 99 %. On obtient ainsi un matériau d'excellente qualité pour un coût de fabrication modique. Il est possible, en particulier, de réaliser des contacts à plusieurs couches, ou des liaisons dues uniquement à la nature du matériau, entre le comprimé fritté et une base massive, par exemple un boulon de contact en cuivre.

Abstract: Le signal audio à transmettre est divisé par un créneau temporel en blocs qui se suivent chronologiquement, ensuite les sections de signal comprises dans les blocs sont converties par transformation en un spectre courte durée, puis les spectres courte durée sont codés et transmis sur la base de critères psychoacoustiques et décodés après transmission, les spectres courte durée sont ramenés par transformation inverse dans le domaine temporel et, finalement, les blocs présents dans le domaine temporel sont joints les uns aux autres. Les blocs sont divisés en sous-blocs et, si les variations de niveau d'un bloc à l'autre dépassent une valeur prédéterminée, les signaux dans les sous-blocs sont soumis à une compression avant la transformation ou à une expansion après la transformation inverse. Pour améliorer le rapport signal/bruit, le signal est amplifié et/ou atténué dans les sous-blocs au moment de la compression en fonction de la puissance moyenne de signal dans les sous-blocs, et il est traité de manière complémentaire au moment de l'expansion. Ledit procédé permet une excellente transmission de signaux audio même si le taux de données est réduit.
