A method and arrangement of apparatus is provided for remotely and selectively determining the existence of a failed fuse in the rectifier circuit of a brushless exciter rotor. A current transformer is disposed about each fuse in such a way that uses the conductor which carries current to the fuse as the primary winding of the current transformer. A light emitting diode is connected in series with the secondary winding of the current transformer. The emitted light, indicating a current flow through the fuse, is sensed by a stationary photodetector. This method senses the existence of a current flow through the exciter fuses and thereby positively determines each fuse that has not failed. Electronic circuitry is used to synchronize the detection operation with the rotation of the brushless exciter rotor so that each fuse is inspected at a time when it is expected to be carrying its maximum current. Since this method looks for the existence of current through each fuse, it operates in a failsafe manner.

This invention is a system of automatically classifying defects both for sorting defective products (metallic surfaces, especially tube surfaces) as to the reworking operation required for correcting the defect, and for classifying the defect as to the preceding manufacturing operation which is the most probable cause of that defect and sending a signal to that operation to provide for adjustments to minimize future defects. The system uses a source of electromagnetic radiation (typically a laser beam which is scanned across the surface) and at least two sensors (adjusted such that the radiation is reflected from a defect-free surface principally received by one of the sensors but that there is a measured amount of radiation in the other sensor). An average signal of the principal sensor is developed as a function of scan position. Threshold circuitry detects when the ratio of sensor signal to average signal varies by a predetermined amount.

An automatic punch press and monitoring system. The monitoring system includes a piezoelectric accelerometer mounted within the stationary die shoe of the punch press, and electronic circuitry including a variable gain amplifier, a detector, an integrator, and a comparator. The monitoring system is manually placed in a "LEARN" mode whereupon the signal produced by the accelerometer during normal operation of the punch press is amplified, detected, and integrated over the time period of one stroke to produce a test function. The gain of the amplifier is automatically adjusted during successive normal strokes of the punch press until the test function is equal to an arbitrary set point, thereby establishing a reference function. The monitoring system is then automatically placed in an "AUTO CONTROL" mode whereupon on each succeeding stroke, with the gain of the amplifier fixed, the test function produced is compared with the reference function. If the test function is above a first high limit level corresponding to a percentage of the reference function and below a second high limit level corresponding to a second percentage of the reference function a check alarm is activated.

Current inrush limiter for incandescent lamps is made by mixing finely divided vanadium sesquioxide and vanadium pentoxide with finely divided glass-forming constituents which include vanadium compound. The mix is compacted and sintered in a substantially inert atmosphere which converts the vanadium oxides to vanadium dioxide maintained in a chemically stable and mechanically strong mass by vitreous binder.

An electric energy meter includes a mutual inductance current transducer formed by primary winding means for direct connection to the current component of an electric energy quantity to be measured. Secondary winding means is inductively coupled to the primary winding means to produce an analog signal that is proportional to the time derivative of the current component. The current responsive analog signal and a voltage responsive analog signal are both applied to an electronic watthour measuring circuit.

An arrangement to eliminate the initial current overshoot which normally occurs when a tungsten incandescent lamp is connected to a power source. The arrangement uses a negative temperature coefficient thermistor having a certain predetermined mass. It has been determined that a practical limiter to eliminate current overshoot can be made only when the mass of the limiter is within a relatively narrow range. The hot and cold resistance of the limiter must also be within prescribed ranges to give a limiter which is not only effective in eliminating the current overshoot, but also efficient in steady state operation such that the limiter dissipates less than 1% of the total power.

The invention relates to a trapezoidal, ladder-type coil configuration positioned as an inverted U to provide a passage thereunder for use in conjunction with magnetic field generating and magnetic field measuring circuitry to detect the presence of metal devices associated with objects, i. e. , parcels or persons, passing through the passage. The ladder configuration of the coil establishes magnetic fields within the passage which exhibit sufficiently strong components in three orthogonal directions (x, y and z) to assure detection of metal devices regardless of the orientation of the metal devices.
