Patent number: 5057100Abstract: A microscope attachment assembly is provided for pivotably mounting a surgical laser to a microscope. A micromanipulator housing is adapted to swing away to an off-axis position to facilitate exchanging the objective lens of the microscope. The spot size of the laser is controlled by shifting the position of a field lens included in a field lens assembly which is shifted along the laser beam by a stepper motor. By toggling a cut/coagulate switch, the field lens is moved between a presetable cut-mode position and a presetable coagulate-mode position.Type: GrantFiled: July 21, 1989Date of Patent: October 15, 1991Assignee: I.L.

Patent number: 5020070Abstract: A compact laser includes an inner quartz tube defining a central bore coaxially disposed within an outer quartz tube sealed with respective end cap assemblies. Each end cap assembly is bonded to a respective end of the outer quartz tube and includes an electrode which at least partially surrounds or is proximate to a corresponding end of the inner quartz tube. Each end cap assembly also supports a mirror element and includes means for adjusting the angular orientation of the mirror elements to bring them into mutually parallel optical relationship. An opening is provided at at least one end of the inner tube proximate to the corresponding electrode which serves to provide a path of lower resistance to direct the region of gas discharge away from the mirror element so that the resulting sputtering is substantially restricted to a region that does not contain the mirror element. The end cap assemblies are fabricated of one or more materials which are thermally compatible and bondable with quartz.Type: GrantFiled: December 14, 1989Date of Patent: May 28, 1991Assignee: I. L.

Patent number: 4390484Abstract: Latex material disposed in a solvent is injected into a sheath fluid into which the solvent is soluble, but the latex is not. The solvent being jetted from a vibrating nozzle forms droplets within the flowing sheath, which is then delivered onto an inclined hydrophobic surface reposing at a low angle to the jet. As the droplet containing stream strikes and flows down the surface, its velocity is taken up as the phase separation process for forming microparticles begins.Type: GrantFiled: July 26, 1982Date of Patent: June 28, 1983Assignee: Ortho Diagnostics, Inc.Inventors: Igino Lombardo, Peter J. Natale

Patent number: 4379682Abstract: A core/sheath vibrating system is utilized to produce core droplets within the sheath, which in turn form into microparticles through phase separation. The flow momentum is first arrested by means of an inclined surface, and the combination is thence deposited, in a continuous, helical channel extending from one end to the other of the inside of a hollow, rotating drum. Rotation of the drum moves the forming microspheres through the channel. At the exit end of the drum, the sheath fluid which carries suspended microspheres, may be filtered, and the microspheres collected and utilized.Type: GrantFiled: April 29, 1981Date of Patent: April 12, 1983Assignee: Ortho Diagnostics, Inc.Inventors: Peter J. Natale, Igino Lombardo

Patent number: 4325483Abstract: A novel method is disclosed for detecting and controlling the flow rate of a perturbed, droplet-forming stream in an electrostatic particle sorting apparatus. Detection apparatus is located at two points along the stream, at a first particle sensing point for sensing the presence of particles within a core portion of the stream, and at a second downstream point, preferably the stream breakpoint, for sensing light scatter and extinction characteristics which are proportional to the surface characteristics of the sheath portion of the stream. Changes in phase shift, pulse width, duty cycle, pulse area, or breakpoint location are detected by analyzing these sheath surface-related characteristics. An error signal is produced in response to such changes which drives an electromechanical fluid flow regulator to increase or decrease the fluid flow rate in a direction which tends to minimize the error signal. The flow rate is thus maintained at a reference flow rate setting.Type: GrantFiled: August 20, 1979Date of Patent: April 20, 1982Assignee: Ortho Diagnostics, Inc.Inventors: Igino Lombardo, Donald E.

Patent number: 4318481Abstract: In order to initiate the charging of droplets at a specific point in time with respect to the formation of those droplets in an electrostatic flow sorting system, the charge phase of the system of the present invention is continuously and automatically adjusted by droplet break point monitoring. The charge phase is therefore flow rate and fluid velocity independent. The break point is monitored by a light source which is focused onto the jet stream at the droplet formation break point, or close to it, and the modulation of light caused by the scatter induced by the sheath stream portion as it passes the focused beam of light is detected via the use of a suitable electro-optical detector. From the output of the electro-optical detector, after appropriate signal conditioning, an electrical wave form is obtained which shape depends upon the shape of the fluid column passing the focus beam.Type: GrantFiled: August 20, 1979Date of Patent: March 9, 1982Assignee: Ortho Diagnostics, Inc.Inventors: Igino Lombardo, Donald E.

Patent number: 4318480Abstract: A novel method for positioning the point of droplet formation in the jetting fluid of an electrostatic sorting device is disclosed. The formation of the uniform droplets is carried out via the application of vibrational energy inparted by a transducer to a jetting laminar flow stream. Previously sensed particles contained within the core portion of the laminar stream are subsequently sorted from the stream as part of a subsequently formed droplet. The disclosed method uses the dependency of the droplet formation point on the amplitude of the wave form applied to the transducer and the modulation of this amplitude to control the droplet formation point distance. The position of the droplet formation point is detected via the use of a light source and photodetector focused on the jetting stream at the position at which the droplet formation point is to be located, and a method for automatically maintaining the breakpoint at that position is described.Type: GrantFiled: August 20, 1979Date of Patent: March 9, 1982Assignee: Ortho Diagnostics, Inc.Inventors: Igino Lombardo, W. Peter Hansen

Patent number: 4318482Abstract: A method for the measurement of fluid velocity and fluid flow rate is described which may be applied to a system in which fluid is caused to exit through an orifice to form a free jet. Optical as well as fluidic properties of the jetting fluids are used to determine the mean velocity of the jet between its point of exit from the orifice and at least a preselected detection point. From the mean velocity determination, the fluid flow rate may also be determined. A marker signal perturbation is applied to the jetting fluid at the orifice, and is detected downstream at a stream sensing point which is located a preselected distance from that orifice.Type: GrantFiled: August 20, 1979Date of Patent: March 9, 1982Assignee: Ortho Diagnostics, Inc.Inventors: Donald E. Barry, Igino Lombardo

Patent number: 4318483Abstract: A novel method and apparatus for automatically setting the time delay for relatively charging droplets in an electrostatic particle sorting system is disclosed. By utilizing a movable sheath sensing means for sensing the light scatter and extinction of this stream, the flow rate and distance to breakpoint are automatically measured and used to calculate and set the timing delay circuitry. This insures that droplet charging at the breakpoint will occur synchronously to produce selective relative charging of those droplets containing particles to be sorted.Type: GrantFiled: August 20, 1979Date of Patent: March 9, 1982Assignee: Ortho Diagnostics, Inc.Inventors: Igino Lombardo, Donald E.

Patent number: 4317520Abstract: A novel method and system are disclosed for detecting the breakpoint of a perturbed flow stream. The scattering and extinction of light caused by a perturbed stream at a preselected flow stream sensing point therealong is measured to produce a real time waveform proportional thereto. The real time waveform is differentiated to produce a differentiated waveform, which is then selectively monitored to distinguish a waveform exhibiting substantially three (positive and negative) peaks per cycle, whereby such detection indicates that at least a portion of the breakpoint region of said flow stream corresponds with said flow stream sensing point. In order to align the stream sensing point with respect to a preselected point within the breakpoint region of the flow stream, the breakpoint region of the stream is caused to move with respect to the stream sensing point until the breakpoint pulse width of one of the peaks corresponds with a preselected pulse width reference.Type: GrantFiled: August 20, 1979Date of Patent: March 2, 1982Assignee: Ortho Diagnostics, Inc.Inventors: Igino Lombardo, Richard A.
