  • Patent number: 10505474
    Abstract: A motor starting state recognition method and device, and a motor. The method includes sampling the counter electromotive forces of any two phases of a motor, and calculating a linear counter electromotive force of the motor according to the counter electromotive forces of the two phases, acquiring a polarity flag bit of the motor, and determining the starting state of the motor according to the polarity flag bit and the linear counter electromotive force. The state of a motor before starting can be recognized effectively using the method, so that the problem where a motor may not be started normally or the success rate of starting is low under the condition of a favorable/dead wind is effectively solved, and the problem where a motor becomes severely worn out and has a shorter service life after frequent starting due to starting failure is avoided. Moreover, the method is simple and highly accurate, and the success rate and reliability of system starting are effectively improved.

In certain example embodiments, a laser source used in sealing the pump-out tube is thermally insulated from the VIG unit and emits a laser beam through one or more windows in an oven towards a mirror located therein. The mirror is located so as to redirect the laser beam onto the pump-out tube to thereby seal it. For instance, a substantially horizontal laser beam emitted from a laser source located outside the oven enters into the oven through one or more windows and is reflected by a mirror towards the pump-out tube to be sealed. The repositioning of the laser source advantageously can change its effective focal length and/or the location of the laser beam, e.g., because of the fixed location of the mirror.

  • Publication number: 20130269391
    Abstract: The present invention relates to a method and system for monitoring and controlling a glass container forming process. The radiation emitted by each hot glass container is measured with measurement unit immediately after the forming machine. The described method normalizes the measurement from glass container to glass container and thereby removes the effects of overall temperature variations between glass containers, changing ambient conditions, and other variations affecting the measurements, which provides a unique quality reference for each glass container. By reviewing this reference for each produced glass container, the quality of the produced containers can be improved.

  • Patent number: 8549883
    Abstract: Systems and methods are provided for controlling temperature in a glass forehearth. In one implementation, a system includes at least one burner disposed in said forehearth, a manifold coupled to said burner, a combustion fuel supply coupled to said burner, a combustion air blower for delivering ambient air under pressure to said manifold, and a controller coupled to said burner for controlling operation of said burner. The system may include a temperature sensor operatively coupled downstream of the blower for providing to the controller a temperature signal indicative of temperature of air delivered to the manifold by the blower. The controller may be responsive to the temperature signal for controlling operation of the burner as a function of current temperature of air fed to the manifold. Operation of the burner may also be controlled as a function of an average air temperature over a preceding time duration.

  • Publication number: 20130235478
    Abstract: The method for measuring profile of an aspheric surface projects an illumination light onto the aspheric surface and introduces a reflected light reflected by the aspheric surface to a sensor through an optical system. The method provides, to a wavefront of the illumination light, a curvature bringing an absolute value of an angle of the reflected light to a smaller value than a maximum value of absolute values of angles of optical system side peripheral rays, locates an exit pupil such that the absolute value of the reflected light angle is smaller than the maximum value, provides, to a sensor conjugate surface, a curvature and a position causing rays of the reflected light not to intersect on the sensor conjugate surface. The sensor conjugate surface, the wavefront of the illumination light and the aspheric surface have a same one of convex and concave surfaces toward a same direction.

  • Publication number: 20130224439
    Abstract: Methods and apparatus for separating substrates are disclosed, as are articles formed from the separated substrates. A method of separating a substrate having first and second surfaces includes directing a beam of laser light to pass through the first surface and, thereafter, to pass through the second surface. The beam of laser light has a beam waist located at a surface of the substrate or outside the substrate. Relative motion between the beam of laser light and the substrate is caused to scan a spot on a surface of the substrate to be scanned along a guide path. Portions of the substrate illuminated within the spot absorb light within the beam of laser light so that the substrate can be separated along the guide path.

  • Publication number: 20130067956
    Abstract: Disclosed is an apparatus for characterizing attributes of a moving glass sheet comprising complementary mechanical material handling technologies that progressively stabilize, position, capture, flatten, and release the lower portion of glass sheets traveling past the apparatus while posing minimal constraint on the top section of the sheet. The apparatus includes a pressure-vacuum (PV)-type device comprising distinct regions such that the glass sheets experience a non-contact but gradual increase in constraining force until the point where measurements can be performed, then a gradual decrease in constraining force until the glass sheets are released from the inspection station. This graduated force technique is applied along the direction of travel of the sheets and may also be applied vertically upwards along the height of the sheet to restrict the motion of the sheet without constraining it at pinch points near the conveyor.
