Jacques Milcamps has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Device for protecting a delay-line modulator
    Patent number: 5023743
    Abstract: A device for protecting delay-line modulators of this type by detecting turn-off of the discharge thyristor by a comparator so as to prevent closing of the charge thyristor as long as the discharge thyristor is in the conducting state. This has the effect of preventing short-circuiting of the feed source.
    Type: Grant
    Filed: August 22, 1989
    Date of Patent: June 11, 1991
    Assignee: CGR MEV
    Inventors: Jacques Milcamps, Jean-Louis Pourre, Jean-Pierre Thiebaut
  • Device for the irradiation of a product on both faces
    Patent number: 5004926
    Abstract: A device for the dual-face irradiation of a product is disclosed. The disclosure lies in the fact that a scanning of the electron beam is done during the pulse so as to prevent a scanning along the axis of the scanning chamber and that the divergent scanning beam is deflected by electromagnets so as to obtain a parallel beam. The device can be applied to devices for the ionization of food products.
    Type: Grant
    Filed: September 8, 1989
    Date of Patent: April 2, 1991
    Assignee: CGR MeV
    Inventors: Michel Vassenaix, Jacques Milcamps
  • Multioperation accelerator
    Patent number: 4760590
    Abstract: A multioperation accelerator simulating more especially cobalt radiation. According to the invention, an electron accelerator of average energy and a set of targets and filters are provided so as to obtain at least one penetration curve similar to that of cobalt and other closely related curves.
    Type: Grant
    Filed: October 14, 1987
    Date of Patent: July 26, 1988
    Assignee: C.G.R. MeV
    Inventors: Guy Azam, Francois Dugardin, Jacques Milcamps
  • Block for partially limiting a radiation beam, and a collimator comprising such blocks
    Patent number: 4534052
    Abstract: The invention provides a block for partially limiting a radiation beam, allowing a first part of this beam to be limited corresponding to a first maximum half angle of opening.This rectilinearly movable block comprises a cylindrical active surface.Because of this active surface, said block defines new limits for the beam without modifying the starting orientation of this active surface in dependence on the positions which it may occupy through its rectilinear movement.

    Assignee: C.G.R. - Mev
    Inventor: Jacques Milcamps
  • Collimator arrangement for a beam of accelerated charged particles
    Patent number: 4055770
    Abstract: A collimator arrangement, which, in association with a charged particle accelerator, makes it possible to produce a uniform irradiation beam throughout a predetermined zone, comprises: a first collimator system, provided with movable elements M.sub.1, M.sub.2, M.sub.3, M.sub.4 and m.sub.1, m.sub.2, m.sub.3, m.sub.4, and a second collimator system associated to the first collimator system and comprising sets of metal strips L.sub.1, L.sub.2, L.sub.3, L.sub.4 and l.sub.1, l.sub.2, l.sub.3, l.sub.4 fixed at four supporting-rods integral with the first collimator system.
