Abstract: A radar correcting system has features for providing a corrected radar receiver reflection to a Doppler process unit. The corrected receiver pulse accounts for variances in phase, amplitude and frequency of the transmit pulses. The system has a phase detector that detects the phase difference between a stable oscillator and the transmit signal, providing a complex video or real and imaginary outputs. An operator that will normalize the transmit pulse is determined. The operator is applied to the reflections received by the receiver antenna to remove from the reflections any vagaries due to varieties in the transmit pulses. The data proceeding to the processor deals only with the objects causing the radar reflection.

Abstract: A magnetic material degausser in which the material to be degaussed is placed within the center of a degaussing coil. A capacitive discharge system is employed for energizing the degaussing coil. The capacitor is repeatedly discharged through the coil in such a way that for at least a portion of the degaussing cycle, the energy applied to the coil decreases with each energization. The magnetic material may be rotated within the coil as the degaussing cycle progresses. In one embodiment of the present invention, the energy discharged from the capacitor first increases and then decreases during the degaussing cycle with each energization of the coil. The rotational speed of the magnetic material within the coil may be related to the frequency at which the capacitor is discharged.

Abstract: A polymeric product having a fabric layer and method of making the same are provided, the fabric layer being provided with opposed sides and at least one polymeric part secured to the fabric layer. The fabric layer comprises a first substantially planar layer of threads disposed in superimposed relation with a second substantially planar layer of threads whereby the threads of the first layer are not woven with the threads of the second layer, the polymeric part effectively being the sole securement that secures the threads of the first layer to the threads of the second layer and thereby imparting its flexible characteristic to the securement between the threads of the first and second layers.

Abstract: An apparatus and method for measuring the angle of at least one side surface of an endless power transmission belt construction of a V-belt type is provided, the apparatus having a first part against which the belt construction is adapted to be disposed in a belt construction measuring position thereof and having a second part pivotally mounted to pivot on an axis thereof and being adapted to be pivotally disposed against the one side surface to indicate the angle thereof by the relation of its pivoted position relative to a reference when the belt construction is against the first part in the measuring position thereof, the apparatus having a moving device operatively interconnected to the second part to tend to move the same toward the belt construction in a direction substantially transverse to the axis thereof when the belt construction is in the measuring position thereof. A method of making such an apparatus is also provided.

Abstract: An interactive ink jet printer prints characters of a language from left to right or right to left in accordance with the direction in which the language is normally written. The signals for the direction in which a motor, which moves ink droplet supply device relative to a recording medium, the signals from a grating, which indicates the direction of motion of the ink droplet supply device and its position relative to a reference position, and the signals for the location of the ink droplet supply device at the reference position are changed whenever the direction of character printing is to be reversed.

Abstract: Disclosed is a multi speed ink jet printer in which alternate vertical scans of the ink stream may be omitted or alternate dots horizontally may be omitted or a combination of the two. In the alternate vertical scan omit mode, a factor of two increases in the speed of printing may be obtained, the same being true of a horizontal row dot omission. Moreover, a combination of the two permits up to a four times speed increase. In essence, while the rate of the ink stream remains constant, the predetermined maximum number of dots (picture elements) in a character box is decreased (resolution decreased) to permit an increase in the speed of printing.

Abstract: An ink jet printer in which the nozzle for emitting a stream of ink drops, the charge electrode for charging ink drops in accordance with signals to be recorded, and the deflection electrodes for providing an electric field therebetween to deflect ink drops in accordance with the magnitude of the charges on the drops, are mounted on a carrier which moves relative to an ink drop record receiving media for forming images indicative of the signals on the deflected ink drops. To compensate for the inclination of the image formed by the carrier movement relative to the recording media, a voltage gradient or difference is applied across at least one of the deflection electrodes so as to effect electric field distortion intermediate the electrodes to thereby compensate for the slant due to carrier motion.

Abstract: Insertion of guard drops on a variable basis within a drop segment of an ink jet raster has been found to be highly successful in producing quality printing. A typical sequence isPgPgPgPggPgggPPgP .rarw. timewhere P designates a printed drop and g a guard drop. The drop on the right is the leading drop of the segment.
