Abstract: ABSTRACT OF THE DISCLOSURE          Vibration sealing apparatus including a vibrating horn and a stationary mandrel having rectangular work faces for oppos-ing each other to seal a rectangular end closure of a thermoplastic coated paperboard carton.  The work face of the vibrating horn de-fines an elongated depression extending between a pair of its op-posite edges with a predetermined depth and also defines a pair of spaced depressions associated with each of the opposite edges.          The spaced depressions have a depth greater than the elongated de-pression and each pair of the spaced depressions forms a pointed configuration that points toward the other pair of spaced depres-sions.  Preferably, the spaced depressions of each pair have the shape of right triangles with the right angle vertices thereof located adjacent the associated edge of the work face in a spaced relationship thereto and adjacent each other in a spaced relation-ship.  One embodiment of the horn has only one of the triangular depressions of each pair overlapping the elongated depression to provide sealing of a "non-tuck-in" carton end closure.  Another embodiment of the work face has both triangular depressions of each pair overlapping the elongated depression to provide sealing of a "tuck-in" carton end closure.  In both horn embodiments, an edge depression extends along one of the edges of the work face from one end of the elongated depression outwardly to one side thereof with the same depth as the elongated depression.  The man-drel work face includes diagonal depressions defining a central junction at which a pair of opposed triangular projections are lo-cated.  Preferably, the diagonal depressions of the mandrel work face include offset portions on opposite sides of the junction thereof and have the same depth as the height of the triangular projections and as the depth of the triangular depressions on the horn work face.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for selectively imparting rotary motion to two spaced apart rotary members which may be used in a web or tape transport mechanism to bi-directionally transport a web or tape.  In a preferred embodiment, this apparatus is used as a tape transport in a magnetic recording and/or playback machine.  A drive roll in the tape transport mechanism selec-tively contacts one of the rotary members.  The drive roll is coupled to a bi-directional drive motor and includes an extend-ing shaft segment.  A string member, tensioned at each end, has an intermediate portion thereof deployed about the extending shaft segment of the drive roll.  Upon rotation of the drive motor in one direction, the drive roll and shaft segment rotate and the frictional forces between the string member and the shaft segment cause the shaft segment  to traverse the string in a corres-ponding direction so as to bring the drive roll into contact with one of the rotary members.  When the drive motor is reversed, the shaft segment rotates in the opposite direction causing the drive roll and extending shaft segment to traverse the string in the opposite direction to urge the drive roll into contact with the other rotary member. In the embodiment wherein this apparatus is used in a tape transport system, the respective rotary members aro supply and take-up reel disc members, respectively, and depending upon the direction of rotation of the drive shaft, tape is trans-ported from the supply reel in a fast forward mode, and is rewound on the supply reel in a fast rewind mode.

Abstract: BE IT KNOWN THAT  CHARLES K. CHOI of 2366 North San Benito Court, Claremont, California 91711, United States of America, having made an invention entitled:        "Process and Apparatus for Rapid Pyrolysis of Carbonaceous Material"   the following disclosure contains a correct and full description of the invention and of the best mode known to the inventor  of taking advantage of the same A B S T R A C T       Carbonaceous materials are rapidly pyrolyzed by feed of the carbonaceous material tangentially to a cyclone reaction-separation zone while introducing a stream of a particulate source of heat into the cyclone reaction-separation zone at an angle inclined to the path of travel of the carbonaceous material so that the streams exchange heat. The cyclone reaction-separation zone induces separation of solids consisting of the particulate carbon containing solid residue of pyrolysis and particulate heat source from a vapor stream which includes condensible and non-condensible hydrocarbon products of pyrolysis.          The particulate source of heat and solid particulate carbon containing residue of pyrolysis are preferably transported to a cyclone burner and heated by partial combustion to a temperature suitable for feed to the cyclone reactor-separator.  Rapid pyrolysis maximizes the yield of middle boiling hydrocarbons and olefins.     When the carbonaceous material is one likely to agglomerate or adhere to surfaces when being heated to pyrolysis temperature, for instance when the material is an agglomerative coal, a higher velocity stream of the particulate heat source may be introduced tangentially into the cyclone reaction-separation zone to form a layer between the injected carbonaceous material and the walls of cyclone reaction-separation zone.                             - 1a -

Abstract: Abstract of the Disclosure A self-locking hinge for use as a pivotal connector between two pivoted members and adapted to lock the members in a fixed angular relation.  The hinge comprises a pair of circular plates that are rigidly affixed to opposite  faces of one mem-ber and rotatably connected to the other member.  The circular plates are used to laterally support both of the members and to guide the other member as it is rotated from a folded posi-tion to a fully extended position.   The hinge is locked in the fully extended position by means of a locking ring that is slidably engaged with the other member.  When such other member is fully extended, the ring engages corresponding locking in-dentations at the periphery of the circular plates and thereby blocks the movement of the other member in one angular direction. The movement of the other member is blocked in the opposite angular direction due to the abutting of the hinge ends of the members.  The members may be returned to the folded position by releasing the locking ring from its engagement with the inden-tations in the circular plates.  The operation of the self-locking hinge of the invention is particularly described with respect to a door security apparatus adopted to engage a door and a floor to resist the opening of the door.  A further embodiment uses the self-locking hinge of the invention to provide a means to convert a stepladder to a straight ladder of increased height.
