  • Radiography apparatus
    Patent number: 3937965
    Abstract: A novel apparatus for radiographic examination purposes comprises an x-ray source emitting a flat beam. Detectors are arranged in the plane of the beam in order each to pick up part of the beam. To avoid the Compton effect, each detector is associated with it an auxiliary detector which only receives the rays emitted by the Compton effect. An electrical circuit forms a predetermined linear combination of the signals respectively picked up by each detector and the associated auxiliary detector, this in order to prevent the errors which are due to the Compton effect when the beam passes through the body being analysed.

  • Process to produce indentations in tubes together with the tube produced by the use of this process
    Patent number: 6170313
    Abstract: A process by which it is possible to make a sharp-angled indentation on hollow tubes without removing any material, maintaining a constant thickness of tube and also without deforming the external diameter and conserving the fiber orientation of the metal, characterized by the fact that a riveting machine is used, which itself is a well-known type of machine, comprising a riveting head fitted to a spindle operating in conjunction with pressing devices and a fixed half-clamp. The riveting head of this machine is replaced by a former adapted to the profile of the indentation required and in particular to its sharp angle. The tube in which indentations are required (1) is positioned between the former and the fixed half-clamp and the pressure devices are operated, causing movement of the spindle in order to allow indentation of the tube (1).

  • Learning SLA violation probability from intelligent fine grained probing
    Patent number: 11916777
    Abstract: In one embodiment, a device obtains a first set of measurements of a path metric for a path in a network that are measured using periodic probing of the path. The device obtains a second set of measurements of the path metric for the path that are measured using fine-grained probing of the path at a higher frequency than that of the periodic probing. The device generates a predictive model that predicts values of the path metric, based on the first set of measurements and on the second set of measurements. The device causes, based on a value of the path metric predicted by the predictive model, traffic to be rerouted from the path to another path in the network.
