Abstract: METHOD FOR PREPARING COLOR-FREE, STABILIZED POLYMERS OF CONJUGATED DIENES OR VINYL AROMATIC HYDROCARBONS OR COPOLYMERS OF CONJUGATED DIENES AND VINYL AROMATIC HYDROCARBONS               ABSTRACT OF THE DISCLOSURE  A method for preparing essentially color-free, stab-ilized polymers of conjugated dienes or vinyl aromatic hydrocarbons or copolymers of conjugated dienes and vinyl aromatic hydrocarbons involves a first stage in which a living polymer of a conjugated diene of vinyl aromatic hydrocarbon or copolymer of a conjugated diene and a vinyl aromatic hydrocarbon is prepared by anionically polymerizing the conjugated diene or vinyl aromatic hydrocarbon, or copolymerizing the conjugated diene and the vinyl aromatic hydrocarbon using a lithium-based catalyst and an inert hydrocarbon diluent. Then, the living polymer or copolymer is terminated by the addition of a suitable terminating agent. Following the term-ination procedure, boric acid is added to the polymer or copolymer in a sufficient amount to prevent or substantially reduce color formation. Then, stabilizing agents are added to the polymer or copolymer and the polymer of copolymer is recovered from the diluent.               BACKGROUND OF THE INVENTION         The invention relates to a method for preparing es-sentially color-free, stabilized polymers of conjugated dienes or vinyl aromatic hydrocarbons or copolymers of conjugated dienes.

Abstract: ABSTRACT        Disclosed is a voltage regulator for an a.c. charging generator that has armature windings and a field winding.  A battery receives the rectified output of the a.c, generator and is charged by the same.  The voltage regulator regulates the output voltage of the a.c. generator by controlling the current flowing through the field winding.        To prevent the output voltage of the generator from becoming too high if a connecting wire joining the rectified output of the generator to the battery is broken, the regulator includes an abnormality detection circuit that compares the rectified output of the generator with the battery voltage and detects an abnormality when these voltages differ by more than a predetermined value.  This arrangement makes it possible to detect the abnormality at an early time before the output voltage of the generator has become harmfully high.

Abstract: ABSTRACT           An improved flat roof structive is provided comprising a substructure and a plurality of insulating elements which are loosely positioned on the substructure.          A corrugated cover member of a substantially rigid material is positioned on the insulating elements at least in an area adjacent the outer perimeter of the roof.  The corrugated cover member has downwardly facing channels which extend in a direction generally from an outer perimeter towards the center of a roof.          The channels are open at their ends facing the perimeter of the roof and are closed or sealed at their ends facing toward the center of the roof.  A strong air flow will create a vacuum under the cover member in wide areas which reduction is greater than the vacuum on the upper surface of the cover member whereby the cover member is pressed downwardly against the insulating elements.  Due to the nearly uniform vacuum under the cover member, i.e. on the upper surface of the insulating elements, the resultant force which acts in the direction of lift-off on the insulating elements is nearly zero.     33,530-F

Several problems have been encountered in commercial processing by prior art procedures.  It has been found recently that, while the speed of pressing is improved by employing moisture contents of less than 5%, these products for some reason cause excessive foaming during final roasting.   It has now been found that high pressing speed can be retained at higher moistures.   It has also been found that reduced extraction  of  phosphatides  which  are  related  to  foam production  can  be  achieved  by  a  process  wherein,  after initially  roasting,  the  nuts  are  pressed between platens constructed  to  remove  expressed  oil  through  the  platen surfaces.  The pressed nuts are then rehydrated and roasted.
