  • Multiple beam laser marking apparatus
    Patent number: 6421159
    Abstract: A laser marking apparatus has a number of individual laser devices (1) mounted at angles to one another. The output ends (2) of the laser devices are disposed closely adjacent to one another and a number of laser beam redirectors (5) are disposed to intercept the laser beams (3) emitted from the laser output ends (2) so as to extend the length of the laser beam paths and to decrease the angle between said laser beams (3).

  • Multi-channel, RF-excited gas discharge laser
    Patent number: 5854806
    Abstract: The invention relates to a multi-channel RF-excited gas laser device which has an elongate tubular dielectric housing 1. The housing has a common elongate ground electrode 2 therein and a plurality of laser channels 4 defined within and extending along the ground electrode 2 adjacent to an interior surface 3 of the dielectric housing. A laser gas is provided within the dielectric housing and a plurality of RF electrodes 7 are disposed adjacent to and extending along an external surface 8 of the dielectric housing 1. Each RF electrode 7 is disposed in registration with one of the laser channels 4.

  • Gas/saline valve with suction control
    Patent number: 4878894
    Abstract: The present invention is a gas/saline valve for use in an gas/saline insufflation system which includes a gas insufflator and a saline source. The gas insufflator is fluidly coupled to a gas inlet of an arthroscopic attachment by a first tubing. The saline source is fluidly coupled to a saline inlet of an arthroscope by a second tubing. The gas/saline valve includes a housing with an open end and a gas/saline control knob. The housing has a first bore and a second bore. The housing also has a first slotted chamber and a second slotted chamber both of which are contiguous to the first and second bores, respectively, and within which the first and second tubings, respectively, are disposed. The gas/saline control knob has a solid cylinder which has a first semi-cylindrical notch and a second semi-cylindrical notch so that when the solid cylinder is disposed inside the housing, the first and second semi-cylindrical notches are aligned with the first and second slotted chambers, respectively.
