Abstract: 1. A percussion apparatus moved by a pressurised fluid, of the type comprising a mobile striking mass (2) in the form of a piston supplying a series of impacts on a tool (3), this piston being slidably mounted in a cylinder (4) which, provided in the body (5) of the apparatus and including ports (6, 7) connected by ducts (8, 9), serves additionally in the sliding of a distributor (10) connecting the chamber (11) situated above the piston alternately to a high pressure circuit (12), for enabling the piston to descend rapidly, and to a low pressure circuit (13) for effecting the return strocke of this piston, characterised in that it comprises, on the one hand, a non-return valve (22) enabling fluid to pass from the chamber (11) located above the strike piston towards the high pressure circuit (12) and, on the other hand, means ensuring that the distributor (10) is displaced sequentially in such a way that, starting from a position in which the chamber (11) located above the piston is connected to the high pressure (12), the distributor is displaced very rapidly as far as a position in which it interrupts the connection between the said chamber and the high pressure, then at a lower, controlled speed, so as to delay the connecting of the chamber (11) to the low pressure circuit (13), so as to enable the maximum amount of restorative energy to be recovered for the entire duration of the isolation of the chamber located above the piston with respect to the high pressure and low pressure circuits, by compressing the fluid isolated in the chamber for the passage of the latter into the high pressure circuit by means of the non-return valve.

Abstract: A process of making a seal ring uses an elastic ring having a sealing lip projecting laterally or inwardly about one, innermost edge. The elastic ring is turned inside out so that the one, sealing-lip edge is then outermost before or during fixedly sealing the sealing lip to a supporting ring, the sealing lip having a thin thickness profile effective in this for upsetting the sealing lip. Turning the lipped, elastic ring inside out also crimps a sealing surface of the lipped, elastic ring, which ring bends to engage a shaft axially with the sealing surface, such that lubricant pockets opening from the sealing surface only to the other, free edge of the lipped, elastic ring are uniformly distributed therein circumferentially about the sealing surface. The baffle or side and bottom surface portions of each lubricant pocket merge evenly with each other to form a single ground surface. The baffle surface portions of each lubricant pocket form an obtuse included angle with the adjacent portions of the sealing surface and the bottom surface portion of each lubricant pocket forms an obtuse included angle with the adjacent sealing surface, opening toward the other, free edge of the lipped, elastic ring.

Abstract: 57 Surgical clip applying apparatus in which clips are delivered to a pair of jaws one at a time for closure around body tissue. The squeezing together of a pair of ring handles causes the jaws to move distally relative to the apparatus. The jaws contact a pair of inclined surfaces on the shaft of the apparatus and are thereby forced together, causing the distal-most clip in a linear array to be closed around body tissue. Release of the handles returns the jaws to the original positions so that another clip closing cycle can be initiated. An escapement mechanism interacts with the jaws to ensure that only one clip at a time from the linear array is delivered to the jaws. A clutch assembly ensures that each step in the clip closing and return cycle is completed in the proper sequence.

Abstract: Un appareil de mesure du niveau d'un signal à mesurer est pourvu d'un oscillateur de signaux de référence, d'un oscillateur de signaux locaux variables, d'un mixeur de type hétérodyne, d'un filtre à bande passante et de moyens de correction automatique du déréglage. Les moyens de correction automatique du déréglage possèdent une mémoire de valeur de crête, un circuit de poursuite et un circuit de calcul de la correction du déréglage. Pour obtenir une sortie de filtre en faisant passer un signal de référence au travers d'un filtre à bande passante, la fréquence d'oscillation des signaux locaux est changée pour obtenir un niveau de crête qui est ensuite mémorisé dans la mémoire de valeur de crête. Ensuite un signal à mesurer est envoyé au filtre à bande passante pour obtenir une sortie de filtre. En prenant le niveau de crête ci-dessus comme référence, les erreurs provoquées par le déréglage du filtre sont calculées par le circuit de calcul de la correction du déréglage.
