Abstract: ABSTRACT OF THE DISCLOSURE       An adhesive composition based on a monomeric ester of .alpha.-cyanacrylic acid and a modifying agent, viz. a monomeric fluorinated ether of dimethylvinylethynylcarbinol of the formula:                         wherein R is CH2(CF2)nH or CH2(CF)nCF3; n = 2 to 10.  Owing to the addition of a monomeric fluorinated ether of dimethlvinyl-ethylnylcarbinol as a modifying agent into the adhesive compo-sition, mechanical strength and water-resistant of the adhe-sive bond are improved.  Thus, an ultimate shear strength of the adhesive bond produced from the adhesive composition according to the present invention after keeping in water for 10 days is equal to 119-185 kgf/cm2.

Abstract: ABSTRACT OF THE DISCLOSURE     A powder coating composition of a mixture of epoxy resins obtained by blending three types of epoxy resins with a curing agent.  One resin is of the epichloro-hydrin-bisphenol-A type.  The other two resins are epichloro-hydrin-bisphenol-A epxoy resins modified with an epoxy-novolac.          Cure is obtained by using a dicyandiamide crosslinking agent.          The composition is useful as a coating for the interior of food and beverage containers.  The composition is also useful as a lining in hot-water services when finely divided poly-vinylidine fluoride powder is added for hydrophobicity.

Abstract: ABSTRACT               A file security system for data files created at a first host system in one domain and recovered at a second host system in another domain of a multiple domain network. Each of said host systems contain a data security device provided with multiple host keys capable of perform-ing a variety of cryptographic operations.  Creation and recovery of a secure data file is accomplished without revealing the keys of either of the host systems to the other of the host systems.  When the data file is to be created at the first host system, the first host system data security device provides a file recovery key for subsequent recovery of the data file at the second host system and enciphers first host system plaintext under a primary file key, which is related to the file recovery key, to obtain first host system ciphertext as the data file.  The file recovery key is used as header information for the data file or maintained as a private file recovery key.  When the data file is to be recovered at the second host system, the file second host system data security device performs a crypto-graphic operation to transform the file recovery key into a form which is usable to decipher the data file.  The second host system data security device then uses the transformed file recovery key to perform a cryptographic operation to obtain the first host system ciphertext in clear form at the second host system.

Abstract: ABSTRACT OF THE DISCLOSURE           The method for regulating the terminal voltage delivered by an independent alternating-current generator consists in measuring the voltage in at least one phase, in measuring and automatically adjusting the frequ-ency with respect to a reference value by putting dissipative resistors in circuit, and in automatically varying the reference value of the frequency as a function of variations in voltage.  The invention achieves stable voltage control which prevents harmful oscillations and is applicable in particular to asynchronous generators which are driven by a natural fluid.

Abstract: Abstract of the Disclosure A coherent shape of a composition characterized by having a core bonded by regrowth of silicon carbide is produced by heating particulate silicon carbide which may be mixed with a minor amount of modifying agent, by means of an uncharged beam of energy, to a temperature above 3000°F. and below 5500°F. and subsequently cooling the resultant coherent shape below 3000° F., both steps being completed within a period of ten minutes.  In the preferred method, unconsolidated particulate silicon carbide is exposed to the energy of a laser beam and the particulate silicon carbide has a particle size within the range of magnitude of ten to three hundred microns.  Upon its initial formation, the shape has a core and a distinctly delineated rind which is attached to the core.  The core has a relatively low resistivity as compared with the rind.  In an igniter formed by the use of a laser, the rind, which appears to be bonded together by quartz rather than by the regrowth of silicon carbide which characterizes the core, is removed, and the core, formed through at least a part of its reach in a serpentine pattern, is densified.

Abstract: "CHAIN DRIVEN SWATHER CANVAS ASSEMBLY"          ABSTRACT OF THE DISCLOSURE         Conventionally, a swather canvas is an endless belt-type construction frictionally engaged around a pair of spaced and parallel rollers and relying on the tightness of the belt or canvas to provide sufficient frictional contact with the driven roller in order to operate.  These belts vary their tension dependent upon wet or dry atmospheric conditions and general stretching of the material and have to be adjusted continuously.  The present device comprises a pair of rollers having chain sprockets thereon and endless chains extending therearound.  A plurality of slatted canvas or rubberized flaps are secured by the leading edges to the chains and the trailing edges overlap the leading edges of the flap immediately there-behind.  Check chains or straps extend between the trailing edges of one flap and the leading edges of the flap immediate-ly behind in order to limit the movement of one flap away from the other particularly along the underside runs of the conveyor and as the flaps pass over the rollers.

Abstract: ABSTRACT    A document stacking ta?    ?s lowered in steps under electronic control as the documents accumulate. A predetermined number of documents are stacked, after which the table is lowered by a predetermined amount.  An optical sensing arrangement is used to determine the effective top of the stack of documents within the limits of "light sensed" and the "absence of light".  If light is sensed, the count is in-creased and the table lowered again; in the absence of light the count is decreased and the table is again lowered.  Thus the stacking table will be lowered by a fixed amount to the level of least error.

Abstract: ABSTRACT         An apparatus and method for winding out and winding in an endless strip situated on a horizontal storage means.  The said strip is wound in concentric coils on the storage means which has at least three rotatable elements and a vertical axis of rotation.          The outer turn of the outer coil is connected to the inner turn of the inner coil.  The outer coil is carried on a first rotatable element and the inner coil is carried on a second rotatable element.          The third rotatable element is situated intermediate the first and second elements.  The device is adapted to draw off the inner turn from the inner coil and subsequently feed it to the outer side of the outer coil.  The device includes drive motors to rotate the rotatable elements so that the angular speeds of the first and second elements are such that the peripheral speed of the outer turn of the first element is the same as the peripheral speed of the inner turn of the second element.  The speeds of the drive motors are controlled by control mechanisms which sense the strip at the points of take-up and wind-out.  Coupling means on the rotational elements cause the intermediate element to rotate at the speed of either the first or the second element.

The table is supported upon a base for substantially free tilting movement generally about a point on a vertically extending axis defined by the base.  A number of proximity transducers for sensing the orientation of the table relative to the base are provided.  A pair of force coils positioned in quadrature about the axis between the base and the table are responsive to the proximity transducers to apply forces between the table and the base to bring the table and the article which rests thereon into a substantially neutral orientation with respect to the base.  The method of the present invention com-prises the steps of placing the article on the table with the article axis at a predetermined position thereon.  Forces are then applied to the table at one or more predetermined locations to bring the table and the article positioned thereon into a neutral orientation.  The amount and location of the applied force are determined to ascertain the amount and location of imbalance existing in the article.
