Abstract: MAGNETO-OPTIC ROTATOR               Abstract of the Invention A single continuous strand of fiber optic material is wrapped about a mandrel to form oval-shaped loops having parallel sides and curved ends.  A magnet is positioned so that its B-field is substantially parallel to the straight portions of the loops.  As light propagates through these straight portions of the loops, its direction of polarization is rotated in accordance with the Faraday effect.  The curved portions are formed to create sufficient linear birefrigence to provide a phase difference of 180 degrees between light in the two orthogonal polarization modes of the fiber.  This causes the Faraday rotations in each of the straight portions to add, rather than cancel.    The magneto-optic rotator of the present invention is useful in a variety of applications such as an optical isolator, a modulator, and a magnetometer.

Abstract: ABSTRACT         A heat shrinkable covering for an article, such as a pipe, comprises a heat shrinkable material in the form of a flexible sheet which is wrapped around the article so that its ends overlap.   The overlapping end portions are bonded together by means of a hold-down adhesive, preferably a shear-resistant adhesive, leaving an adhesive-free region at the interface.  Heat is applied externally to the overlapping end portions so as to effect a fusion bond at the adhesive-free region of the interface, and the sheet is heat-shrunk onto the article in known manner.  The covering offers the advantages and convenience of application  common to conventional wrap-around sleeves, while having the intrinsic strength properties of a seamless tubular sleeve.

Abstract: MATRIX CHARACTER RECOGNITION SYSTEM            Abstract of the Disclosure A character recognition system is disclosed in which each row of a plurality of parallel rows of binary signals representing the configuration of an unknown character is sequentially compared to a plurality of templates, each representing a known character.  Each of the rows of signals is compared to feature character-istics of the unknown character twice.  The rows of signals are first shifted one signal position and com-pared.  The signals are then compared in their original position.  Only those rows of signals which are required to contain a feature characteristic of the unknown characters are compared.  The resulting data is utilized by a data processor apparatus identifying the unknown character.

Abstract: "ABSTRACT":          "Tunable Fabry-Perot interferometer and X-ray display device having such an interferometer".         A tunable Fabry-Perot interferometer the supports of which for the two parallel mirrors consist of bundles of optical fibres and the mirrors are provided on the ends of the fibres, may be used advantageously in an X-ray dis-play device between the display screen on which the visible X-ray image is displayed, and the television camera tube.          By using the Fabry-Perot interferometer as a light attenuator in such a device the situation in which the camera tube is overdriven when making an X-ray record, can be prevented by causing the reflection coefficient of the mirrors in the visible range of the spectrum to be 99% or more, the half width of the transmission wavelength pass-band of the Fabry-Perot interferometer, can be made less than 50 nm.

Abstract: ABSTRACT           METHOD AND APPARATUS FOR SEVERING A COEXTRUSION FOR MAKING AN ENROBED FOOD PIECE         Methods and apparatuses are described for manufactur-ing, from a coextrusion, food pieces wherein an inner food is fully or partially enrobed by an outer food.   In one embodi-ment the inner food is a dough that is enrobed by an outer dough by severing the outer dough with a blunt severing edge on a severing element which, as it enters the coextrusion, simul-taneously draws the outer dough over the inner dough on both sides of the element to form the food piece.  A coextrusion of an inner dough inside an outer dough is formed below a die with the extrusion of the inner dough periodically interrupted to form a region in the coextrusion where there is a greater amount of outer dough.   A pair of severing elements are operatively located at a predetermined distance below the die where convergence of the severing elements cuts the extrusion in a region having a greater amount of outer dough while simul-taneously drawing the outer dough over the inner dough above and below the severing elements.   Several embodiments are described.
