  • Device for timing reconstruction of a data channel transported on a packet network and its process
    Patent number: 6760395
    Abstract: A memory for data accumulation includes an input on which such data are entered as a stream of input data under the control of an input timing signal and an output starting from which the data entered in memory are read as a stream of output data under the control of a reconstructed timing signal. A phase-locked loop uses this input timing signal as an input signal to generate a corresponding phase-locked output signal. Of such phase-locked loop output. A device is provided to measure residual phase wander and act on the transfer function band of the phase of phase-locked loop output which is preferably without ring filters.

  • Vertebral implant and setting tool therefor
    Patent number: 6752832
    Abstract: A spinal implant for engagement between a pair of vertebrae has a pair of parts displaceable relative to each other along an axis and each adapted to engage a respective one of the vertebrae. One of the parts is formed with a screwthread engaging a nut that bears axially on the other of the parts and that is formed with an externally accessible array of gear teeth. This implant is set by a setting tool having a holder fittable with the other part, a rotary member in the holder, and a gear on the rotary member meshable with the teeth of the one part when the holder is fitted to the other part.

  • Conveyor for bottle-filling machine
    Patent number: 6748983
    Abstract: A conveyor chain has lower pins and is displaced in steps through a station. Respective pairs of plates have holes fitted to the pins and confronting cutouts together forming seats shaped to fit complementarily around necks of bottles. Horizontally displaceable supports in the station above the chain carry downwardly projecting upper pins. An actuator raises the plates in the station and thereby slides the holes of the plates in the station from the lower pins onto the upper pins. The arms and upper pins are moved apart when the plates are on the upper pins to open up the seat so that a bottle can be fitted to or taken out of the seat. The arms and upper pins are moved together when the plates are on the upper pins to close the cutouts around a bottle positioned between them, and then lowered back down onto the lower pins.

  • Automatic milling and drilling machine
    Patent number: 6745455
    Abstract: A machining apparatus has a lower housing part, an upper housing part having a lower side, and a plurality of support posts fixed to the upper and lower parts and holding the upper part fixedly at a spacing above the lower part. A tool holder displaceable parallel to a horizontal tool axis on the lower side of the upper housing part carries a chuck rotatable about the tool axis and can hold a machining tool. A supply station on the lower part offset horizontally perpendicular to the tool axis from the tool holder is can hold a plurality of the workpieces. A cross slide connected between the upper housing part and a workpiece chuck displaces the workpiece chuck in a horizontal direction perpendicular to the tool axis and in a vertical direction to displace a workpiece between the station and a position aligned on the tool axis with the tool chuck.
