Abstract: METHOD OF CLASSIFYING AND COMMINUTING       A GYPSUM ORE OR THE LIKE              ABSTRACT OF THE DISCLOSURE          A method is disclosed  or separating a relatively soft component from a relatively hard component of mineral ore and then comminuting the softer component.  The separa-tion is performed by impact crushing the ore to reduce the softer component to particulate material of a smaller dimension than that of the harder component after which the components are separated by screening.  The comminution is performed by further impact crushing the softer component to further reduce same and separating sufficiently small particles.  Relatively large particles are also removed and the remainder of the softer component is recycled through the comminution process.  The method is primarily applicable to the separation of chert from gypsum and comminuting the gypsum in the processing of gypsum ore.

Abstract: ABSTRACT OF THE DISCLOSURE       The disclosure of the present invention teaches an apparatus and method for forming ductile metal sheets into shaped bodies.  In particular, it is directed to forming with the so-called superplastic metal alloys which under appropriate conditions of temperature and pressure exhibit high ductility and an ability to flow.  The apparatus for use in forming ductile metal sheets into shaped bodies comprises first and second open-ended, annular chambers which are relatively movable, while maintaining their open ends in register with one another, between a position in which the open ends meet and a position in which the open ends are spaced apart; a plate in at least one of the chambers which is movable independently of both chambers in directions parallel with the directions of relative movement between the chambers between a first position in which it constitutes a gas-tight sealed base for the one chamber and a second position in which it is adjacent to open end of that chamber. Thus an improved press for use in forming ductile metal sheets into shaped bodies is disclosed which is more flexible than prior art presses.  Also an improved method as taught for forming these shaped bodies is disclosed using a "snap back" technique.

Abstract: A METHOD OF ASSEMBLYING A SEALED STRUCTURE                ABSTRACT OF THE DISCLOSURE           A method of connecting a first shell to a second shell to establish a unitary sealed structure.  A bead of a diaphragm assembly is connected to a first peripheral surface on the first shell to establish a first sealing surface and to define a first chamber between the diaphragm assembly and the first shell.  A spring attached to the diaphragm assembly engages the second shell.  A force applied to the second shell compresses the spring to bring a second peripheral surface therein into engagement with the bead on the diaphragm to establish a second sealing surface and define a second chamber between the diaphragm assembly and the second shell.  A vacuum evacuates air from the first and second chambers to establish a pressure differential between the first and second chambers and the surrounding environment.  This pressure differential acts on the first and second shells to urge the first and second peripheral surfaces against the diaphragm to establish a unitary structure.  Thereafter, the force applied to hold the first and second shells together is removed and the relationship between the first and second sealing surfaces is observed for a fixed time period.  Should air from the surrounding environment enter into either the first or second chamber, the pressure differential is sufficiently reduced to allow the spring to separate the first and second shells to indicate a non-conformity between the first and second shells and the diaphragm.  If the first and second shells remain together during the fixed time period, the first and second peripheral surfaces are thereafter crimped together to establish the unitary sealed structure.

Abstract: COUPLING FOR LINED PIPE     ABSTRACT OF THE DISCLOSURE            Disclosed are coupling joints for interconnecting the ends of metal conduit sections having plastic liners to form a continuously lined conduit and methods for making such joints.          The opposed open ends of lined pipe are fitted with flanged end face collars which cover the end faces of the pipe and the open ends are then joined in an abutting relationship within a coupling sleeve by interference fit coupling.  The coupling sleeve carries an internal sealing band which mates with the outer edges of the opposed collars to fully seal the joint and the ends of the coupling sleeve are radially crimped into a corresponding groove in the pipe to mechanically interlock the joint.  Fully lined couplings are also formed by fitting an end face collar in the pin end of one lined conduit and interference fitting the pin end into an unlined bell on a lined conduit.

Abstract: ABSTRACT OF THE DISCLOSURE         In a synchronous video detector circuit using a phase-locked loop, the synchronous detection of a video IF signal is effected with a synchronous carrier signal reproduced by the PLL including a voltage-controlled oscillator.  Each of a phase comparator of the PLL and a synchronous video detector has its input terminal connected to an output terminal of a video IF amplifier by untuned coupling, and arranged on the output side of the synchronous video detector is a phase-locked mode detector for detecting that the PLL is in its phase-locked mode.  The phase-locked mode detector is adapted to control the band width of a low-pass filter of the PLL in either a narrow band mode or a wide band mode and the low-pass filter is controlled to operate in the narrow band mode only when the PLL is in the phase-locked mode of operation.  The black and white noise included in the output signal of the synchronous video detector are both cancelled by a noise cancellation circuit including a black noise detector for pulse noise cancellation purposes.

Abstract: ABSTRACT OF THE DISCLOSURE           In the manufacture of non-returnable packages for milk and other beverages laminated packing material is seal-ed to itself along linear sealing zones by causing outer thermoplastic layers of the packing material to fuse together.          The strength of the seal obtained depends upon the thermo-plastic surfaces being free of impurities, e.g., oxide coat-ings or residues of the contents of the package.  In spite of the presence of impurities a strong seal can be obtained if the thermoplastic layers, within a limited region of the seal-ing zone, are pressed against each other with such a force that molten thermoplastic material is made to flow to adjoin-ing regions, since in this case the thermoplastics are blend-ed to such a degree that the seal-preventing layer of impuri-ties is broken.
