Abstract: In-line printing and coating method achieves high coat weights (e.g, over 0.7 lb./1,000 sq.ft.) characteristic of blister seal operations and/or high gloss and high scuff resistance requirements, substantially without deleterious slinging. A high volume of coating is applied to a substrate by a coating cylinder supporting a resilient coating transfer surface consisting of an array of laser engraved coating-carrying indentations having substantially equal volumes that are uniformly distributed. An impression surface is positioned adjacent to the coating cylinder, positioned to impress a substrate between the coating transfer surface and the impression surface. A supply roll has a surface for applying liquid coating to the resilient transfer surface. The supply roll surface and the resilient transfer surface are in pressure contact, and adjacent surfaces of the supply roll and the coating cylinder rotate in the same direction.

Abstract: A beam electronically steers, in real time, a multielement sensor array at radio frequencies. A sensor array is configured in one embodiment with orthogonal loops and orthogonal dipole elements. Each loop and dipole combination generates a polarized output signal which is routed, via a connection matrix, to an equal number of signal splitters. The resulting modal patterns are then routed to networks having quad hybrids and digitally user-controllable vector modulators. The signals outputted from the quad hybrids and the vector modulators of each of the networks are inputted to separate combiners. The signals outputted from the separate combiners of the networks are then recombined in combiners. The signals outputted from these combiners define the azimuth around the Z-axis, the elevation around the Y-axis, and the elevation around the X-axis, respectively.

Abstract: A nonelectronic device tracks and homes in on a target to be destroyed by a projectile having a body in which the device is carried. An optical lens disposed in a nose cone of the projectile body receives and focuses infrared radiation or heat from the target, which is an electromagnetic field that may be emanating from an exhaust plume of an incoming enemy intercontinental ballistic missile. A detector converts the radiation focused by the lens into thermal energy. A Golay-type cell receives the thermal energy and converts it into a fluid signal that is transferred via a nonelectronic coupler to a fluidic circuit. A fluidic rate gyro seeks the target and guides the projectile towards the target to be destroyed. A key advantage of the invention is that the nonelectronic infrared heat tracking device is comprised of inert mechanical elements and fluids. Therefore, the device is unaffected by intense magnetic and electromagnetic fields, except for those fields within the design band of the detector element.

Abstract: A method for joining together two ceramic items involves the steps of applying microwave radiation to the ceramic items, simultaneously applying compressive forces to the ceramic items in order to force such ceramic items together, and continually monitoring the joint being formed between the two ceramic items. An apparatus of three elements carries out the method. These elements are a single mode microwave applicator; a compressive force applicator; and a nondestructive evaluator for monitoring the formation of the joint.

Abstract: A method for joining together two nonoxide ceramic items involves a preliminary step of either creating a vacuum or overpressurizing a cavity, followed by the steps of applying microwave radiation to the ceramic items, simultaneously applying compressive forces to the ceramic items in order to force such ceramic items together, and continually monitoring the joint being formed between the two ceramic items. An apparatus of four basic elements carries out the method. These elements are a vacuum/overpressurization system; a single mode microwave applicator; a compressive force applicator; and a nondestructive evaluator for monitoring the formation of the joint.

Abstract: A navigational device consisting of a magnetic compass containing a pattern having a specified relation of black-to-white density with respect to angle, rotating with the compass card, a light source for illumination of the pattern, pairs of sensors mounted in the compass and responsive to the light intensity reflected from or transmitted through the pattern, the output from one pair of sensors being proportional to the sine of the angle made by the sensor pair zero reference line with respect to Magnetic North, and the output of the other pair of sensors being proportional to the cosine of said angle, both outputs being suitable for operation of a remote indicating compass, and various modifications thereof for making the outputs of the sensor pairs proportional to the sine and cosine of the angle between a manually settable desired heading or angle and the angle of the said sensor pair zero reference line with respect to Magnetic North.
