Abstract: Abstract of the Disclosure A hot rolling method using a hot finishing mill including a pair of work rolls each having a taper ground end at one end of its barrel and arranged one above the other with the taper ground ends being on opposite sides so as to locate both edges of a plate-like material to be rolled in respective zones of the taper ground ends.  According to the invention the work rolls are cyclically shifted in their axial directions within a range so as not to permit the both edges of the material to come out of the taper ground ends of the work rolls,  thereby preventing edge built-ups of the material and simultaneously effecting crown-controlling of the rolled material.  The work rolls are finely shifted and simultaneously a bending action is applied to the work rolls in a manner to eliminate a bending action acting upon the work rolls caused by the material being rolled by the work rolls.  The work rolls are cyclically shifted, while a distance from an edge of the material to a starting point of the taper ground end of the work roll nearliest to the edge of the material is variably set so as to decrease dependently upon increase of thermal expansion of the work rolls. Stepwise variation in shifting distance of the work rolls per unit number of rolled material is varied in a rolling cycle.

Abstract: Abstract of the Disclosure A catheter or the like is steerable through cavities within a body and aimable toward organs or tissue within the body.  The catheter includes an elongated tubular member having a proximal end and a distal end for insertion into the body, a plurality of temperature-activated memory elements in the distal end of the tubular member, and a core for supporting the memory elements.  Each memory element assumes a first shape when heated to a predetermined temperature.  A sleeve is provided to couple slidably each memory element to the core so that each memory element is permitted to slip in relation to the core and also to couple each memory element so that movement of one element results in movement of the other elements.  Each memory element is moved to a second shape when the memory element coupled thereto is heated to the predetermined temperature.  A control system adjacent the proximal end of the tubular member allows an operator to control selectively the temperature of each temperature-activated element to deflect the distal end of the tubular member so as to either direct the course of the tubular member or to direct the distal end of the tubular member toward an organ or tissue within the body.

Abstract: ABSTRACT OF THE DISCLOSURE   A document scanning apparatus is disclosed which provides a scan and rescan motion to a scan carriage using only mechanical drive cornponents. Motion of a rotating photoreceptor is transferred, via drive pulley components to a main drive shaft having, in a first embodiment, a pair of pulleys fixedly mounted at the ends. The pulleys drive cables which, in turn, drive the scan carriages of the disclosed system in a scan or rescan direction, dependent upon the drive pulley rotation. The drive pulley rotation is controlled by a movable hub assembly on a drive shaft and by a linkage mechanism which is periodically engaged by the scan carriage at a beginning or end of scan position.          Mechanical engagement of the scan carriage with the linkage mechanism causes a reversal of the drive pulley rotation and hence a reversal of the scan carriage direction of travel. In a second embodiment, a rack and gear arrangement is used to drive the scan carriage.

Abstract: "Subscriber Line Interface Circuit Having Means for Combining DC and AC Feedback Signals"            ABSTRACT OF THE DISCLOSURE       A subscriber line interface circuit comprises a balanced amplifier having positive and negative inputs for amplifying a voltage thereacoss to generate a pair of mutually complementary voltages across true and complementary outputs.  Four resistors of a first value are respectively connected between a subscriber tip line and the negative input, between a subscriber ring line and the positive input, between the negative input and true output and between the positive input and complementary output.  Two resistors of a second value smaller than the impedance of the subscriber loop are respectively connected between the tip line and the complementary output and between the ring line and the true output.  A DC feedback circuit is connected to the complementary output to generate a DC feedback signal according to a desired variable DC power feeding characteristic.  An AC feedback circuit generates an AC feedback signal proportional to a differential voltage across the tip and ring lines and inversely proportional to a desired AC impedance.  The DC and AC feedback signals are combined in a circuit which supplies to the negative input a current corresponding to the combined signals.

Abstract: ABSTRACT OF THE DISCLOSURE     A synthetic resin pipe which includes two identical complementary, extruded semi-cylinders joined by electron magnetic bonding along abutting longitudinal edges to form a smooth walled cylindrical pipe.  In one embodiment of the invention, the smooth walled pipe forms an internal sleeve or liner within an external corrugated pipe having contiguous circumferential corrugations over its length, and having the troughs of the corrugations bonded to the outer surface of the internal sleeve.    In the method for forming the pipe, two identical flat plastic sheets are extruded, then vacuumed formed into semi-cylinders each having radially outwardly pro-jecting longitudinal flanges extending from opposite side edges thereof.  A paste or dispersion containing ferromagnetic particles is then applied to the flanges on the sides thereof adjacent the concavity of the res-pective semi-cylinder.  The semi-cylinders are next arranged in registry to form a cylinder with the flanges abutting.  Radio frequency electromagnetic radiation is then directed through the semi-cylinders at the location of the ferro-magnetic particles to fuse the semi-cylinders to each other adjacent the flanges.  The flanges are then sheared away along shear lines tangential to the cylindrical side wall of the pipe thus formed.
