Abstract: APPLICATION FOR CANADIAN PATENT                           SPECIFICATION     ABSTRACT OF THE DISCLOSURE     Two rotary toolheads are mounted on diametrically opposed sides of an index table which is rotatable about a vertical Y axis and which supports a fixture carrying a stationary work-piece.  Both toolheads are slidably mounted on the bed of the machine for movement along a horizontal Z axis perpendicular to the Y axis.   Both toolheads are journalled for rotation about the Z axis and can be simultaneously rotated about the Z axis and moved axially therealong.  Two tool slides are slidably mounted on the face of each toolhead for cross-feed movement along an X axis and a U axis, respectively, both of which are perpendicular to the Z axis.  The tool slides are moved by DC motors mounted on the corresponding toolhead and mechanically coupled to the tool slides through ball screw mechanisms.  The motors rotate with the toolheads and are electrically coupled to the NC controller through slip rings.   To machine a cylin-drical surface on the workpiece coaxial with the Z axis, the corresponding toolhead is rotated and simultaneously moved a-long the Z axis while the cutting tool slide remains stationary.          To machine a flat surface on the workpiece perpendicular to the Z axis, the corresponding toolhead is rotated without movement along the Z axis and the cutting tool slide is moved along its cross-feed axis.   If a constant cutting surface speed is de-sired, the rotary speed of the toolhead can be automatically varied by the NC controller in inverse proportion to the vari-ation of the radius of the circular path followed by the cut-ting tool point so as to maintain a constant cutting surface speed in spite of the cross-feed movement.  If a constant chip thickness is desired, the cross-feed rate can be varied auto-matically by the NC controller in direct proportion to the vari-ation in the rotary speed of the toolhead to maintain a constant chip thickness in spite of the speed variation of the rotary toolhead.  To machine an axially curved surface on the workpiece, the corresponding toolhead is simultaneously rotated and moved along the Z axis, while the cutting tool slide is moved along its cross-feed axis at a feed rate which produces the desired axial curve in conjunction with the Z axis feed rate.  An unin-terrupted transition can be made from cutting a flat surface perpendicular to the Z axis to cutting an axially curved sur-face which is tangent to the flat surface.

Abstract: TAPE CONTROL APPARATUS                  ABSTRACT  OF THE DISCLOSURE     Apparatus for controlling the speed, direction and tension of tape transported between a supply reel and a take-up reel.  First and second drive motors are coupled to the supply and take-up reels for applying oppositely directed torques thereto, thereby bi-directionally driving the tape between these reels and applying back-tension to the driven tape.  A speed detector detects the transport speed of the tape and generates a speed control signal proportional thereto.  Torque voltage generators are responsive to the speed control signal for generating first and second torque voltages which are deter-minative of the torques respectively applied to the supply and take-up reels by the drive motors, the first and second torque-voltages changing differentially with respect to each other as the speed control signal changes.  The torque voltages are applied to motor drive means which is responsive to such torque voltages for producing first and second drive signals which, in turn, are applied to the drive motors to control the torque applied by the drive motors to the supply and take-up reels, whereby the tape is transported at a substantially constant speed.  A command signal generator generates command signals to establish the speed and direction at which the tape is trans-ported, and the first and second torque voltages are adjusted in response to the command signals to differentially change the drive signals produced by the motor drive circuit so as to differen-tially change the torques applied by the drive motors to the. supply and take-up reels.                             -i-

Abstract: ABSTRACT OF THE DISCLOSURE       Precise alignment, required for a low-loss electro-magnetic interconnection between single and multiple stranded optical fiber conductors or waveguides, is achieved in a conventional electrical connector block.  A pair of guide bushings having precise outer dimensions are secured respectively to the termini of the optical fiber conductors and these bushings, in their respective connector blocks, are adapted for insertion into a split tube having a precisely dimensioned inner diameter.  The optical fiber conductors, being concentric with the bushings, thereby are precisely interconnected.          For single fibers, the bushings and the split tube are cylindrical.  for multiple stranded fibers or fiber bundles, the bushings and the split tube have identical polygonal cross-sections, which match precisely identical polygonally shaped fiber-receiving openings in the bushings.  Physical contact between the electromagnetically coupled fiber optic conductors is prevented by a flat annular shim which is loosely secured-to the split tube and contacted by the bushings.
