Abstract: SYSTEM AND METHOD FOR STABILIZING              ASYNCHRONOUS STATE MACHINES     ABSTRACT OF THE DISCLOSURE         To prevent a race in an asynchronous state machine branching from one state to either of two others, depending on which of two control signals arrives first, one of the signals is latched in the state just ahead of the branching state.  The branching then takes place in the branching state upon arrival of the other signal but in a direction de-termined by the value of the latched signal.  If the latched value indicates a wrong order of arrival, the machine re-leases the original latched value and latches an updated value of the one signal and returns to the branching state.          The looping, with unlatching and relatching, contunues until the latched value causes branching to take place in the proper direction.

Abstract: ABSTRACT OF THE DISCLOSURE         An automatic sheet feeding device for feeding sheets of low rigidity and high coefficient of friction, such as thin documents and thin carbon backed sheets.  The device includes feeding rollers, separating rollers, a rotate in mechanism for rotating the separating rollers, and a regulating mechanism for regulating a torque, applied to the separating rollers.  A torque tending to rotate the separating rollers in a direction in which the sheets are fed, is applied thereto by the feeding rollers, and a torque, tending to rotate the separating rollers in a direction opposite the direction in which the sheets are fed, is applied thereto by the separating roller rotating mechanism through the regulating mechanism for regulating the torque applied to the separating rollers which is a friction clutch.          By adjusting the torque transmitting force of the friction clutch, one of the two torques is selectively applied to the separating rollers depending on whether or not the sheets are held between the feeding rollers and separating rollers.

Abstract: ABSTRACT OF THE DISCLOSURE     A mechanism for use in a cassette tape recorder automatically changes the mode of the recorder when the end of the tape is reached by sensing the cessation of rotation of the pinch roller.  A mode change lever having an elongated hole with converging sides that receives a cylindrical portion of the pinch roller is biased by a spring so that the cylindrical portion engages the con-verging sides and the mode-change lever tends to rotate in a first direction.  Once the pinch roller ceases to rotate, the mode-change lever is moved in a direction opposite the first direction and so that it cooperates with a mode-change drive assembly rotated by the capstan.  The mode-change lever is then displaced and releases a mode key, so that the mode of the recorder is changed and is typically shut off.

Abstract: FIBER OPTIC DYE AMPLIFIER                         Abstract A  fiber optic  amplifier  is  disclosed,  comprising a fiber  optic,  monomode  waveguide  having  a  core  and cladding.  A portion of the cladding over a predetermined region is removed and replaced by an active medium capable of  absorbing  light  energy  at  a  first  wavelength  and emitting light energy at a second wavelength.  The active medium is a lasing dye that has an index of refraction adjusted to be slightly less than the index of refraction of the fiber core.   The amount of cladding removed is adjusted such that a predetermined amount of penetration of the evanescent field from a pump light signal coupled into an end of the fiber penetrates the active medium.  A probe signal to be amplified causes stimulated emission from  the  excited  dye molecules  by  penetration  of  its evanescent  field  into  the dye  in  the region where the cladding is removed.   In the preferred embodiment a recirculating pump is used to circulate dye through a cavity placed over the fiber where  the cladding portion  is removed.   The dye molecules in contact with the surface formed by removal of the  cladding  are  continually  changed.    A  temperature control unit maintains  the temperature of the dye such that its index of refraction remains tuned to an amount just less than the index of refraction of the core.

Abstract: ABSTRACT OF THE DISCLOSURE   monitor assembly is provided herein for monitoring the effectiveness of anodic protection of carbon steel vessels containing a corrosive liquor, e.g. pulp digesters.  The monitor has two identical carbon steel monitor coupons mounted on a mount rod, one coupon being in electrical connection with the anodically-protected carbon steel vessel, the other being out of electrical connection with such vessel.  A reference electrode is mounted on the same mount rod in such a way that the reference electrode, but not the mount rod, is wetted by the liquid contents within the carbon steel vessel.  In this novel combination of elements, the mount rod, the metal components of a sealing gland and a metal spacer disc are made of any metal with sufficient mechanical and chemical stability to withstand the corrosive environment of the liquid contents of the carbon steel vessel, as well as being able to withstand the mechanical stress.  An electrically-non-conductive sleeve and electrically-non-conductive spacer elements are formed of any electrically-non-conductive material having sufficient mechanical and chemical stability to withstand the corrosive environment of the liquid contents of the carbon steel vessel, as well as being able to withstand the mechanical stress.

Abstract: Abstract of the Disclosure Semi-bulk transport bags having wide lifting members, each lifting member  formed from a plural layer folded strip of plain fabric woven from flat ribbon tape, of the same type as used for the bodies of the bags; these relatively stiff lifting  members are anchored at the tops of the bags, and are positioned to distribute lifting stresses across wide segments of the side panels.  One construction uses four lifting loop members, one at each corner of a rectangular bag; the edges of the ends of each loop are overlapped and tacked into the bag corner by the corner seams that join the side panels of the bags, without folding the side panels over the lifting members, materially reducing manufacturing costs.  In another construction, using only two lifting members, the ends of each lifting member are anchored into wide vertical hems on just two side panels of a rectangular bag, allowing use of a lighter weight plain fabric material for the other two side panels without sacrifice of bag strength.  In yet another construction using four lifting members, the opposite ends of each lifting member are attached to top portions of the side panels of the bag body but spaced from each other; variations include a rectangular bag and a generally circular bag.  Each lifting member is formed with a single twist to stiffen the lifting member and to equalize load stress when the bag is lifted.
