Abstract: ABSTRACT OF THE DISCLOSURE A procedure is disclosed for continuous extrusion coating by the use of a coating die of a hollow core material with a highly expanded polyolefin composition containing a volatile organic liquid blowing agent, the improvement comprising externally, cooling the outer surface of the extruded molten mass of expandable polyolefin resin, at the point at which the molten mass begins to foam, by by contacting the surface with a cooling gas or water to allow the pressure of foaming to be exerted inwardly and also to cause the growth of foam to proceed in the direction of the internal core for thereby enabling the poly-olefin foam to adhere fast to the hollow core and giving rise to a coating hav-ing a smooth surface condition, wherein the expanded polyolefin foam has an ex-pansion ratio of not less than 3. This thereby enhances the fastness of ad-hesion of the highly expanded polyolefin foam with the hollow core material and at the same time facilitates the release of the two materials thus joined.

Abstract: Abstract of the Disclosure Benzopinacols represented by the formula:       wherein R1 is hydrogen, alkyl or aryl; R2 and R6 independently are selected from the group consisting of hydrogen, halogen or trifluoromethyl;          R3 and R5 independently are selected from the group consisting Or hydrogen, halogen and alkyl or, when taken together with R4, represent a tetramethylene group; and R4 is selected from the group consisting of hydrogen, halogen, alkyl, alkoxy and phenoxy;          with the proviso that when both of the ortho positions of the phenyl groups at which R2 and R6 are attached are substituted, the substituent is fluorine.  These and other benzopinacol compounds can be prepared by an improved process comprising irradiating a diarylketone with UV radiation in a non-polar hydrocarbon solvent mixed with an alcohol.  The volume ratio of the non-polar hydrocarbon solvent to alcohol is between 3:1 and 8:1.  The benzopinacols are useful, for example, in imaging materials, such as with certain dyes that are reactive with the ketyl radicals that can be released from the benzopinacols upon heating.

Abstract: ABSTRACT OF THE DISCLOSURE      A terminal box for a dynamoelectric machine utilizes a flux shield system wherein a plurality of flux shields are interposed between the wall of the terminal box and a high voltage bushing.  Cooling fluid is passed through the flux shield system to maintain all parts at a safe, low temperature. In one embodiment of the invention, a first inner flux shield member of high electrical conductivity and low magnetic permeability is spaced from but surrounding the bushing. A second outer flux shield member of low electrical conductivity and high magnetic permeability is spaced between the first shield member and the terminal box wall.  Passages and openings are provided to allow cooling fluid to circulate over the respective shield members and the wall of the terminal box without providing a path for transmission of flux from the area surrounding the bushing to the terminal box wall.  The fluid flow path and the suction ducts for removing coolant from the terminal box are arranged to insure maximum flow of cooling fluid over the most heated portions of the terminal box wall.

Abstract: ABSTRACT OF THE DISCLOSURE        A thyristor pulse control circuit of the kind having a main thyristor and a commutation circuit including a commutating capacitor, and a by-pass contactor connected across the main thyristor, is provided with means for applying a gating signal to the main thyristor immediately before the contacts of the by-pass contactor close and also immediately before the contacts of the by-pass contactor open, to prevent arcing at the contacts.  The application of the gating signal is inhibited if a comparison of the voltage across the commutating capacitor with the load current flowing immediately before the by-pass contactor closes, indicates that the load current is too great to be safely commutated by the voltage across the commutating capacitor.  Thus, arcing of the contacts of the by-pass contactor is greatly reduced while, at the same time, the possibility of a failure to commutate the load current flowing through the main thyristor due to insufficient charge on the commutation capacitor is eliminated.
