Patent number: 5117108Abstract: In a laser microprobe interface for a mass spectrometer, such as a Fourier transform mass spectrometer, the focusing optical system (1) and the viewing optical system (4) are arranged in the cell holder (5) of the spectrometer itself. The focusing optical system (1) can be moved by an adjustment means (2) so as to make allowance for the variation of the focal distance with the wavelength of the primary ionization laser beam (3) and is arranged at the center of the viewing optical system (4) of the achromatic inverted cassegrain type. The latter optical system provides perfect definition of the image and a high magnification together with a good depth of field and good laser focusing. The arrangement of the focusing optical system (1) at the center of the viewing optical system (4) also allows the focusing optical system (1) to be interchanged with other ionization means.Type: GrantFiled: May 4, 1990Date of Patent: May 26, 1992Assignee: University of Metz, Etablissement Public Caractere Scientifue et CulturelInventors: Jean-Francois Muller, Francois Tollitte, Gabriel Krier, Marc Pelletier

Patent number: 4514615Abstract: A circuit for controlling the power supply to an electrode of the shielded type, such as that used in a shielded metal arc welding process (SMAW) whereby to protect a user from electric shocks. The control circuit is a protection circuit which serves to protect welders against electric shocks by decreasing the circuit voltage between the electrode tip and the workpiece to be welded. An AC or DC power supply may be used to feed the electrode. The control circuit is comprised of a high impedance voltage source applied to the electrode, a detection circuit for determining the level value of the impedance appearing between the electrode and the workpiece. The detection circuit compares the impedance thus detected with a threshold impedance and generates a control signal when the detected impedance is lower than the threshold impedance. The control signal operates a driver circuit which energizes a power feed device serially connected between the electrode power supply and the electrode itself.Type: GrantFiled: April 23, 1984Date of Patent: April 30, 1985Assignee: Hydro-QuebecInventors: Raynald Simoneau, Jean-Marc Pelletier, Antonio Di Vincenzo, Jean-Paul Boillot

Patent number: 4434413Abstract: An improvement in an electrical circuit-breaker module of the narrow modular type connectible in stacked relationship with a plurality of modules in an electrical distribution panel. Each of the modules is associated with respective electrical distribution branch circuit and is provided with circuit interruption means for interrupting its associated electrical distribution branch circuit upon the occurrence of predetermined fault and overload currents on the branch circuit. The improvement comprises a controlled switch means mounted in at least one of the modules, without altering the thickness of the module in the vertical plane. The controlled switch means is connected in series with the circuit interruption means and is operable by command means exteriorly or interiorly of the module to assume an open or closed contact condition.Type: GrantFiled: October 20, 1981Date of Patent: February 28, 1984Assignee: Hydro-QuebecInventors: Jean-Marc Pelletier, Yvon Dion
