Abstract: The sleep-apnea syndrome is classified into a so-called central type caused by an abnormality in the respiratory center, an obstructive type by an upper airway obstruction, and a mixed type by a combination thereof. Among the rest, the obstructive type is often observed clinically and is considered to be caused by a morphological abnormality in the upper airway tract, such as tonsillar hypertrophy or micrognathia, or by a tonus of the upper airway muscle for broadening the airway. The inventors of this application have clarified by experiments that the upper airway can be recovered from obstruction which causes apnea stimulating the genioglossus, which is one of the dilator muscles of the upper airway, with pulses of a frequency of 40 to 150 Hz, a peak value of 1 to 50 volts and a rise-up time constant of 0.2 seconds or more, and that control of the start and stop of the electric stimulation with apnea detection signals would make it possible to automatically take measures to deal with apnea even at night when it is particularly difficult to find a fit of apnea.

Abstract: A lining wear sensor comprises a discrete multi-layered strip (9) of electrically conductive material which is stuck to the edge (6) of a friction pad (2) so that it wears with the pad with a consequent change in electrical resistance of its layer (11) of resistive material. This can be measured by suitable contacts to indicate the wear condition of the pad. 
     When the resistive material has a large temperature coefficient of resistance, temperature changes in the strip (9), and in the friction material itself, can be monitored to provide an indication of the operating characteristics of the brake, for example whether the pad (2) is being applied evenly to the disc, or whether it is in permanent rubbing contact with the disc.

Abstract: The invention relates to a weapon launched towards a target with the aid of a launching system (3) and more particularly its capacity for manoeuvre towards a target which may be masked or otherwise and mobile or otherwise in the direction of its trajectory. In order to enhance the effectiveness of a weapon, it is essential to improve its precision without considerably increasing the cost of production of such a weapon. In order to that, a weapon containing a useful load (7), is equipped with a deployable carrying system (8) fixed to the said load. During ejection of the carrying system (8) and of the load of the weapon (1), the carrying system is deployed. The carrying system comprises a wing structure (15) fixed on extensible support means (14), the assembly being connected to the load by rigging lines (18) whose length varies according to the data transmitted by at least one sensor positioned on the end of the load so as to provide guidance. Application of the carrying system according to the invention to any weapon intended to observe or attack an area which can be masked or otherwise in order to detect and destroy, if required, a designated target which can be moving or otherwise. <IMAGE>

Abstract: The invention relates to a device for orienting loads on a linear conveyor. In particular, it makes it possible to pivot parcels on a drive-roller path of palettisers in order to facilitate their placement on pallets. According to the invention, the device has the shape of a controlled stop (3) which is movable in a transverse direction. The movement of the stop (3) corresponds either substantially or precisely to the peak of a sine wave. This makes it possible to create a substantially fixed point of contact with the load (2). The invention is of interest in particular to manufacturers of handling equipment.

Abstract: Dans le système de réglage d'élévation selon la demande principale, la liaison par engrenage entre le transporteur supérieur et le pied presseur comporte un régulateur triangulaire qui règle automatiquement la hauteur du transporteur supérieur. C'est de préférence un régulateur hydraulique avec un vérin hydraulique divisé en deux chambres par son piston de réglage. Un élément de mesure de la pression différentielle se présentant sous la forme d'un élément à ressort transfère au régulateur sous forme de perturbations les efforts de réaction qui agissent sur le pied presseur articulé pendant le processus de couture. Dans le but de simplifier cette solution, un élément hydraulique de mesure de pression différentielle est prévu à la place d'un élément mécanique de mesure de pression différentielle. Les deux chambres (82a, 82b) du vérin hydraulique (59) sont interconnectées via deux soupapes de surpression (71, 71') reliées en anti-parallèle. Chaque soupape de surpression (71, 71') comporte de préférence un clapet antiretour (R) à ressort et une soupape de limitation de pression (D) reliée en aval de ce dernier.

Abstract: Un procédé et un dispositif nouveaux servent à brûler des déchets spéciaux et à fondre (vitrifier) des cendres volantes en même temps. A cet effet, la consommation des scories et des gaz perdus est effectuée séparément, selon des procédés industriels différents. La température du four tubulaire tournant est réglée par adjonction d'air de combustion, selon la température des scories fondues, le cas échéant par combustion sous-stoechiométrique. La consommation des gaz perdus se fait par adjonction d'air activé de combustion ou d'oxygène dans des zones de haute turbulence d'aggrégats complémentaires. Des agents vitrifiants peuvent être ajoutés au four tubulaire tournant. Les cendres volantes sont liées à des substances énergétiques et ajoutées directement aux scories fondues à la sortie du four tubulaire tournant, de sorte que leur fonte soudaine, leur mélange intime et leur liaison aux scories du four sont assurées par la rotation du four. En outre, il est important de noter que l'exploitation sous-stoechiométrique permet de réduire radicalement les besoins en déchets liquides et/ou en combustibles supplémentaires, d'augmenter la performance du four tubulaire tournant et de réduire la formation de NOx.

To the trunk there is, at the desired level above ground, attached a holder which carries an explosive charge and can from the ground be mounted on the trunk, whereupon the charge is detonated and the trunk section above the cut-off level severed from the section below. In this way the top section is either directly released from its support or can conveniently be so released.

Abstract: In order to prevent the blocking up of the outer fold gaps (2) of a tubular filter, in particular for a vacuum cleaner, or at least to make it more difficult, and, in the case of an accumulation of dirt, to be able to remove the latter easily, the fold gaps are designed in such a way that they widen, in particular constantly, towards the lower end of the filter when it is in use. This also means that the fold cross-section or the inside space (17) of the fold is reduced from the top to the bottom to the same extent. The fold walls can rest directly on one another at the lower end. The same applies correspondingly to adjacent walls of two folds (1). If the fold gaps are left free at the bottom, the dirt can readily emerge downwards when the filter is jolted or shaken. <IMAGE>
