  • Patent number: 9617496
    Abstract: A sulfurized alkaline earth metal (e.g., calcium) dodecylphenate is prepared by reacting (i) dodecylphenol with (ii) calcium hydroxide or calcium oxide in an amount of about 0.3 to about 0.7 moles per mole of dodecylphenol charged and (iii) an alkylene glycol in an amount of about 0.13 to about 0.6 moles per mole of dodecylphenol charged; and reacting the product of the first step with sulfur in an amount of about 1.6 to about 3 moles per mole of dodecylphenol charged; and thereafter optionally reacting the product with additional calcium hydroxide or calcium oxide and with carbon dioxide so as to form an overbased phenate. The product thus prepared has reduced levels of monomeric dodecylphenol.

  • Patent number: 8759074
    Abstract: The invention relates to a device (7) for applying electromagnetic energy to a reactive medium, with said device being designed to be connected to an electromagnetic radiation generator using a means of transmission (4) of said radiation, with the device being remarkable in that it includes at least one loss transmission line (70) that features an interface that transfers electromagnetic energy towards the reactive medium, with said transfer interface being arranged so as to assure, throughout the length of the said line, a pre-determined distribution cross-section for the density of the electromagnetic energy delivered to said medium by said line. The invention also relates to a device for processing, by electromagnetic radiation, of a reactive medium including such an application device. The present invention can be applied to the sector of devices for thermal treatment of a reactive medium, specifically by microwave or high-frequency radiation.

  • Patent number: 8758696
    Abstract: The device for electromagnetic radiation treatment of a reactive medium includes an electromagnetic radiation generator, a reactor containing the reactive medium, and a device for transmitting the electromagnetic radiation generated by the generator to the reactive medium contained in the reactor. The device includes a wave guide for transmitting the electromagnetic radiation from the generator and a coupling means arranged to allow transfer within the reactive medium of the electromagnetic energy transmitted by the wave guide. The wave guide includes a curved segment in a general “U” shape forming a return loop from the wave guide. The device further includes a separation wall that isolates the generator form the reactor, with the reactor being connected to the curved segment. The curved segment extends at least partially from one side of the separation wall to the opposite generator.

  • Patent number: 6894786
    Abstract: A substrate is etched in a vacuum enclosure in a process which generates plasma light emission. The process is monitored by passing emitted light via a window, a thin film narrow band filter and a “Fabry-Perot” etalon to a detector. The output signal from the detector is analyzed by shape recognition techniques to derive a measure of the progress of the process. The shape recognition preferably makes use of digital filtering and comparison with reference data derived from the theoretical analysis or from a calibration run.

  • Patent number: 4344983
    Abstract: The present invention concerns the technique for the manufacture of composite materials.It relates to a process and an apparatus which make it possible continuously to deposit refractory materials, in particular boron, onto a conductive filament heated by means of the Joule effect and by means of a current produced by a high-frequency generator.It also relates to the apparatus for carrying out the said process.This new process has the advantage that it makes it possible, in particular, to obtain a fibre of high tensile strength, while at the same time maintaining a high speed of travel.

  • Patent number: 4141802
    Abstract: In panels for use particularly in the aeronautics industry comprising a metal support foil to which is adhered a fiber-reinforced metal matrix layer, the fibers being of high mechanical strength and modulus, the invention provides the improvement of interposing a thin layer of a bonding metal or alloy between the support foil and the fiber-reinforced metal matrix layer.The bonding metal layer serves to improve the adhesion of the metal matrix to the support foil and enables the metal matrix layer to be produced under less severe conditions.
