Abstract: Method of making a reinforced pneumatic tire in which the tire body is formed in at least two sections each including a side wall and a plurality of annular bands each including an annular reinforcing belt embedded in an elastomer. The tire sections are assembled in a mold with the annular bands of each section interleaved with the annular bands of another section and the elastomer is cured to form an integral tire body. The tire may be formed of two reinforced sections with the interleaved bands forming the annular tread section of the tires, or as three reinforced sections, including two sections each including a side wall and annular bands and a connecting section including annular bands with reinforcing belts which are interleaved with the annular bands of the other two sections to form a tread section. An annular, elastomeric tread section may be formed separately and bonded around and to the annular bands of the reinforced sections.

Abstract: For use with a remote reading magnetic compass a digital circuit for computing an output indication of compass heading to provide an output heading indication corrected for changes between successive compass readings. Compass heading is corrected in accordance with a weighted average value of the difference between successively read headings to provide an output which is representative of a true or weighted average heading and an output of the magnitude and sense of such difference.

Abstract: A high speed, electro-optical printing system for producing images, particularly images of type characters, on sheet material. A radiation sensitive, image-recording material preferably in sheet form is moved at a controlled speed past an array of relatively small, emitters of radiation actinic to the image-recording material. The emitters are electrically energized selectively and for varying durations to expose and produce images in the image-recording material as it moves past the emitters.The emitters may include light or heat emitting diodes or the ends of optical fibers each optically coupled at its other end with an actinic radiation source. The image-recording medium is carried on a sheet material and the system includes means for moving the image-recording sheet past the array of emitters and a processor for treating the exposed sheet to form a stable, visible image.

Abstract: A pelorus system for automatically providing an output display of the magnetic bearing of sighted objects. A pelorus sight is coupled to a shaft encoder which provides output pulses representative of the relative angular bearing of a sighted object. Pulses are also provided by a digital magnetic compass and representative of magnetic heading. The pulses from the pelorus encoder and from the digital compass are processed to provide an output indication of magnetic bearing of a sighted object.

Abstract: For use in an electro-optically sensed magnetic compass a photoelectric control circuit in which the duty cycle of the illumination source is varied to energize the source only until a valid electrical output signal is detected.

Abstract: The present disclosure is directed to sanitary conveyor belts of polypropylene or other suitable plastic material having an integrally hinged construction defined by spaced notches which define the hinge points as well as drive engagement points between the belt and the sprockets having teeth which mate with the spaced notches. The belt construction also has one or more longitudinal notched grooves which defines a tracking and aligning groove which mates with a multi-faceted aligning member arranged polygonally about the perimeter of the sprockets which support the conveyor belt to preserve its alignment with the drive sprockets.The conveyor belt is used with an air levitation means in the form of a plenum chamber having openings to direct low pressure air against the underside of the belt to reduce friction drag when the belt is loaded.

Abstract: The present disclosure is directed to a condyle hinge breaker for shrimp which have been positioned upon a support at its terminus with the condyle hinge between the fifth and sixth shell segments of the shrimp positioned immediately above the terminus of the support and a position holding means has rendered the shrimp static relative to the support with only its sixth shell segment and telson extending there beyond. At this point pressure means is applied from the dorsal toward ventral side of the shrimp causing the sixth shell segment and telson to be wrapped about and beneath the terminus breaking the condyle hinge between the fifth and sixth shell segment.
