Patent CA-1331490-C (CA)
Inventor: WACHTLER WILLIAM R

Abstract: ABSTRACT A computerized gauge measures dimensions, typically in the range of 6.1865" to 6.1917" accurate to ? .001", typically the diameter of a steel railroad car axle.  It indicates the in-tolerance/out-of-tolerance condition of each measurement as well as the quantitative measurement value.  The gauge simultaneously senses the temperature, typically within a range of -20°F to 100°F ?1°F, of the axle workpiece. In consideration of the predetermined coefficient of expansion of the workpiece, the gauge calculates the dimension that the workpiece would exhibit should it be thermally brought to a predetermined, 59°F by convention, reference temperature.  From the workpiece-temperature-compensated dimension resulting from such calculation, and from manually preset dimensional tolerance ranges, the axle is indicated to be (i) oversized but repairable, (ii) within an acceptable size range, (iii) undersized but repairable, or (iv) undersized and unrepairable.  The gauge may further sense its own temperature and, in consideration of another predetermined coefficient of expansion as besuits the gauge, calculate a gauge- and workpiece-temperature-compensated dimension.  All temperature sensing is normally integral with the measurement process.  Compensation for temperature-induced dimensional variation is typically at an accuracy of better than ?.0001" for steel axles of 6+" diameter over a temperature range of greater than 100°F.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus and method is disclosed for controlling the temperature of a thermal print head and individual dot elements thereon, thereby optimizing print quality and reducing the thermal and electrical stress on the thermal print head.  Hysteresis control determines the amount of energy supplied to each dot element in the thermal print head.  Peak temperature control determines the width of the pulses supplied to the dot elements on the thermal print head.  Pre-heating control raises the temperature of each dot element when the dot element has been idle for a predetermined period.  Substrate temperature control maintains the temperature of said thermal print head at a predetermined value.

Abstract: BAND REJECTION FILTERING ARRANGEMENT                          Abstract A  band  rejection  filtering  arrangement  utilizing bandpass filters each terminated by a matched load.  A quadrature hybrid circuit divides the input signals and applies them to the bandpass filters.  Signals within the rejection band are dissipated by the filters and matched loads,  whereas  desired  signals  are  reflected.    The reflected signals are then combined by the quadrature hybrid circuit to provide the band rejected output.  This arrangement is made switchable between an all pass mode and the band rejection mode by providing PIN diodes between the quadrature hybrid circuit and the bandpass filters.

Abstract: Methods for generating holograms from a computer model of any object employ a combination of numerical and optical means. An illumination model and the light dispersion properties of the object are specified. The hologram is synthesized from a plurality of smaller hologram elements.      Each individual element sustains a field of view of the object. The light rays from the object lying within the field of view and along the lines of sight are sampled by the computer. The sample density should not exceed the resolution limit set by the size of the hologram element . Each light ray is specified by a direction and an amplitude function. The hologram element is obtainable from a Fourier Transform of the sampled rays. In one embodiment, optical means are employed to physically reproduce the sampled light rays using coherent radiation. The reproduced coherent light rays are then interfered with a coherent reference beam to form the hologram element. Alternatively, the interference pattern is calculated directly by the computer and is printed to form the hologram element.
