Granted: 1990-12-18
Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a system for aligning a high-power laser apparatus to transmit a high-power beam along an optimum beam path to an adjustable remote beam receiver and for aligning the beam receiver for optimum reception of the high-power  beam.   A  low-power  visible laser is directed along the path to be followed by the high-power laser and a viewer such as a video camera is used for rough alignment.  A pellicle, a partially reflect-ing mirror,  and three low-power beam detectors are used with the low-power laser to align the beam transmitter with the beam receiver.  Alignment of the beam receiver with the beam transmitter  is checked by a high-power laser beam alignment checking system.  This alignment checking system employs an annular beam detector mounted near the beam transmitter and a second beam detector mounted near the beam receiver.  A beam intensity reducer is used to reduce the intensity of the high-power beam for use in alignment since prolonged direct contact by a full-power beam with the detectors would damage the detectors.  A method for aligning the laser beam transmitter and receiver is also described.

Abstract: ABSTRACT OF THE DISCLOSURE        An improved performance ferromagnetic self-regulating heater.  Constant alternating current is applied to a layered structure including at least one ferromagnetic layer.  One or more layers of non-magnetic material is added to the ferromagnetic layer in such a way that the power factor of the heater is very sig-nificantly increased above its value in the absence of at least one of the layers.  The alternating current flows through the different layers in varying quantities depending on layer composition, temperature and Curie point of the ferromagnetic layer.  The structure generates heat by resistive heating as a function of the power applied.  In one embodiment a single layer of non-magnetic, high-resistance material is in intimate electrical and thermal contact with one surface of the ferromagnetic material.  Below the effective Curie temperature of the ferromagnetic layer the current is mainly confined in the non-magnetic layer which heats with greater efficiency due to better resistive and impe-dance characteristics.  In a second embodiment a further non-magnetic, low-resistance layer is added to the opposite surface of the ferromagnetic material.  Here the majority of the current is switched from the high-resistance to the low-resistance layer as the heater approaches effective Curie.  By these means impedance matching circuit losses can be substantially reduced and energy is saved in high power systems based on the power factor.

Abstract: ABSTRACT OF THE DISCLOSURE A device for the retention of slag during drawing off of molten metal from a vessel provided with a tap hole has a circular closure of a size to effectively close said tap hole and an elongated tapered member extending downwardly from said closure having several generally planar faces arranged circum-ferentially thereof, said device having a specific gravity less than the specific gravity of said molten metal and greater than the specific gravity of said slag.

Abstract: ABSTRACT     The invention provides a cutoff control system hav-ing a capture range equal to the length of the image (signa-ture) which is highly tolerant of spurious transitions, such as lateral shifting and instantaneous interruptions of the web.  The highly pipelined hardware correlation unit, cooper-ating with several high speed RAM devices having independent address generators, is used to cross-correlate new patterns with a reference pattern.  An illustrated system for relat-ing a cyclical machine operation to the position of images on a web includes position adjustment means responsive to control signals for varying the effective position of the machine operation along the moving web, means for generat-ing image signatures indicative of the image at respective sampling intervals during the matching operation cycle for respective machine cycles, means for selectively generating reference pattern indicia from a first image signature and for selectively generating comparative indicia from a succ-essive image signature, means for generating correlation co-efficients in accordance with the differences between the reference pattern and shifted versions of the comparative indicia, means for processing the correlation coefficients to determine which of the comparative indicia produced the largest correlation coefficient and generating an indicating signal in response thereto, and means for generating the control signals to the position adjustment means in accord-ance with the indicating signal.
