Abstract: ABSTRACT            A method of measuring the thickness and refractive index of a transparent material is based on phase difference measurements.  A Zeeman effect laser generates a light beam containing two radiation components with slightly different frequencies which produce a first beat with one another at the end of an optical path external to the material.  The beam is also split into its two radiation components and two further beats are generated between a first radiation component, which is made to follow a path outside the material, and second radiation components obtained by making the second component follow two dif-ferent paths within the material.  The phase differences between these further beats with respect to the first beat are measured by a phase-comparison system, and refractive index values as well as the thickness values can be computed.

Abstract: Abstract:    The invention relates to the making of sheet articles of non-conducting material for identification.  The article is marked by the incorporation therein of a small quantity of very thin conductive fibres capable of both absorbing and reflecting microwaves.  The part of the article containing the fibres is placed in the path of an unguided microwave beam and the excess microwave energy arrested over that reflected is measured.  An output signal is produced which is representative of the excess. The output signal is characteristic of the fibres and can be used to authenticate the articles of non-conductive material, such as banknotes, passports and bonds, because the characteristic signal is very difficult to simulate by a counterfeiter.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatuis for stirring the non-solidified regions of a cast strand, the strand being formed in a mold of a continuous casting machine, is disclosed.          Molten metal enters the mold in a tap stream or jet from a casting pipe or enters by direct injection into the mold.  A static magnetic field is generated across the mold and acts in the path of the tap stream in the melt in the mold.  The magnetic field, due to the movement of the metal stream, retards the velocity of the tap stream in the melt and splits the tap stream, thus stirring the melt.  The magnetic poles which generate the static magnetic field are positioned substantially adjacent the casting pipe or the mold so that certain portions of the melt will be located at the side of the casting stream and will not be directly influenced by the stream.  These portions, upon retardation of the stream, will be stirred by the interaction of the magnetic field and the currents produced in these portions.

Abstract: ABSTRACT OF DISCLOSURE     A machine and method for applying heat shrink labels or the like to articles such as containers having cylindrical body portions and an end portion or portions adjoining the body portion and sloping inwardly therefrom.  The label has a length such that its leading end overlaps the trailing end and a seam is formed at the overlap.  The label is secured to the article by adhesive between the leading end and the container and by adhesive between the overlapping leading end and trailing encl.  The label is of a width such that it projects beyond the junction or junctions of the end portion or portions with the body portion  resulting in free standing edge or edges which are then heat shrunk onto the container by heat from an external source.  A tongue is interposed between the heat source and the seam at each free standing edge or edges.  This tongue serves as a heat shield to moderate application of heat to the seam.  Most advantageously the end of each tongue is wedge shaped so that as it is extended it acts as a wedge to urge the free standing edge toward the article.  In a preferred embodiment of the invention heat is applied in the form of hot air in stages such that the free standing edge or edges are shrunk commencing with their junctions with the container and progressing to the outer edges whereby no air is entrapped.

Abstract: MULTIELECTRODE PROBE AND CIRCUITRY   AND PROCESS PERTAINING THERETO     Abstract of the Disclosure A system, method and probe for monitoring the corrosion rate of different metals in identical corrosive fluids and under identical conditions, such metals being employed as electrodes other than reference electrodes in a probe having also a reference electrode.  The preferred probe comprises a probe body holding at least four elec-trodes, where one is placed in the center and the others around it in a circle.  The center electrode is preferably used as a permanent reference electrode.  Each electrode on the circle can then be connected in turn to a channel on a multistation PAIR meter as test and auxiliary electrodes, whereby the corrosion rate on each of them can be monitored in turn.  This arrangement greatly enhances the utility of the multistation PAIR meter and with only two entry ports in a system, all channels can serve to answer specific questions on specific electrodes or metals.  The novel probe can also be used with a one channel PAIR meter employed with a multi-station manual switch.     In an alternative electrode arrangement, the center electrode is used as a permanent auxiliary electrode while the system itself is used as a reference electrode and a plurality of test electrodes are employed.

Abstract: APPARATUS AND PROCESS FOR PRODUCING PREDOMINATELY IRON ALLOY CONTAINING MAGNESIUM                           Abstract of the Disclosure Apparatus and process are described for producing predominately iron alloys that contain magnesium which alloys have particular utility for treating cast iron to form ductile and compacted graphite irons.    The alloys are produced under pressure of an inert gas maintained above the vapor pressure of the magnesium at the melt temperature.          The alloy melt is rapidly solidified in a chill mold which imparts a certain amount of constraint to the melt to provide a high magnesium recovery in the alloy and a clean, safe, economical operation.  As a result of rapid solidification, the magnesium is retained in the alloy as a fine dispersion or separate phase which is of advantage for high magnesium recovery in the alloy and for a high magnesium recovery in the cast iron when treated with the alloys of the present invention.    Any desired composition of alloy may be produced.  Best results are obtained when the alloys contain by weight from about 0.5 to 4.0% magnesium and optionally from about 0.1 to 10% silicon, from about 0.5 to 6.5% carbon, from about 0.05 to about 2.0% cerium and/or other rare earth elements and from about 0.1 to about 10% nickel.  One or more of the optional ingredients may be employed in the alloy of the present invention.

Abstract: ROBERT A. MELONI          IMPROVED DOT MATRIX PRINT HEAD     ABSTRACT OF THE DISCLOSURE           Hammer actuators are mounted on a support.  Instead of moving the entire massive support to traverse the paper for each line, only a low inertia member, which positions the impact ends of the print wires, is moved.  The internal structure of the member facilitates minor curvature of the print wires as the member moves. The member is rapidly reciprocated relative to the supports but "dwells" for a short time at each extreme to permit indexing of the paper. Enhanced graphic capability is possible because each print wire can print a plurality of dots for each line.

Abstract: ABSTRACT OF THE DISCLOSURE An improved switch for a high-voltage device in which ignition of a power cartridge moves an insulative piston located in a conductive member away therefrom and into a passageway in an insulative liner. The piston moves a contact through the passageway and away from the conductive member to break an electrical interconnection between the conductive member and the movable contact, thereby opening the switch. The switch includes an insulative housing engageably surrounding, holding and fixing the relative positions of the conductive member and the liner. An interiorly relieved extension is formed at and about one end of the liner, and an exteriorly relieved region is formed in and about one end of the conductive member, whereby the region may be telescoped into and conformally engage the inside of the extension so that the conductive member and liner partially overlap along a tortuous interface so as to increase the interrupting capability of the switch by enhancing the isolation between the power cartridge and the passageway.

Abstract: ADHESIVE BINDING STRIP            ABSTRACT OF THE DISCLOSURE           A binding strip for binding a stack of sheets together in a book-like fashion.  The binder strip includes an elongated substrate made of a formable material such as a strip of heavy paper.  A relatively wide band of heat-activated adhesive extends down the center of the substrate.  Two relatively narrow bands of heat-activated adhesive are disposed on opposite sides of the central adhesive band.  The central adhesive band, which has a low viscosity at the application temperature, serves to bind the edges of the sheets together and to the substrate.  The side adhesive bands, which are at least one-half as thick as the central adhesive band and which have a high viscosity at the application temperature, functions to secure the first and last sheets of the stack to the substrate.  The first and last sheets serve as the cover sheets of the bound volume.  The side adhesive bands also function to contain the low viscosity central adhesive during the binding process.  It is preferred that the side adhesive bands be spaced apart from the longitudinal edges of the substrate a minimum amount so as to form a pair of edge gaps.  These gaps increase the gripping strength of the molten side adhesive bands during the binding process.

Abstract: Abstract The invention provides a method of measuring the spot size of a single-mode optical fiber, comprising the steps of measuring the far field pattern of a beam emitted from one end of the single-mode optical fiber in a range from the radiation angle at which the far field pattern is maximum to the radiation angle at which the far field pattern is reduced 25 dB or smaller, calculating the near field pattern from the measured far field pattern by the use of Hankel's transform, and determining the spot size from the calculated near field pattern according to a prescribed definition formula.  This method avoids the use of a vidicon camera or lens systems which have produced errors in known measurement systems.
