Abstract: A SHIFT REGISTER SUITABLE FOR CONTROLLING THE ENERGIZATION    OF A MULTIWINDING MOTOR            Abstract of the Disclosure A shift register is described particularly adapted for selectively controlling the energization of the windings of a stepping motor so as to provide selective overlapping phase energization.  The shift register consists of four stages each having master and slave sections with each stage controlling the energization of an associated motor winding.          A shift register control unit, responsive to stepping and directional signals, directs the shifting of information between the various stages of the shift register.  In response to a step high input signal, a high level of one shift register stage is shifted in a selected direction to the adjacent stage with both stages directing the energiza-tion of their respective motor windings.  Similarly, in response to a step low signal the low levels of the shift register stages are shifted in a selected direction to their adjacent stages causing the deenergization of the respective motor windings.  Step high and step low signals are applied simultaneously to cause the output of each shift register stage to shift its level to the adjacent stage in the selected direction.

Abstract: CHANNEL MULTIPLIER PLATE CRT SCAN CONVERTER               AND SCAN CONVERSION METHOD     ABSTRACT OF THE DISCLOSURE           An electron beam scan conversion method and apparatus based on the gain recovery or "dead" time characteristic of channel electron multipliers. The waveform of an electrical signal is written on the input face of a channel multiplier plate with an electron beam. Then, within the dead time of the written channels (typically about 1-100 msec.), the plate's input face is scanned in a predetermined raster pattern with a constant current beam. During the scanning step, an output signal is derived that corresponds to the difference in emission in response to the scanning beam between the channels in the written area of the plate and those outside that area.

Abstract: TORQUE CONVERTER TRANSMISSION          Abstract of the Disclosure:           An angle drive transmission having an angle drive input shaft and bevel gearset driving an input sleeve shaft rotatably supported on each side of the driven bevel gear by bearings in an end wall and a central wall of the main housing to ground axial thrust to the main housing.  The sleeve shaft extends through the end wall and is connected to drive, transmit axial thrust and support the clutch wall of an outboard-mounted rotary torque converter housing.  An outboard cover housing has its open end secured to the main housing at the end wall, encloses the rotary housing, and has a central ground member rotatably and axially slidably supporting the impeller wall of the rotary housing.  The torque converter has a bladed impeller on the impeller wall, a bladed turbine adjacent the clutch wall connected to drive an output shaft rotatably mounted in the sleeve shaft and connected to transmit axial thrust to the sleeve shaft, and a bladed stator between the impeller and turbine mounted on the ground member.  A clutch on the clutch wall, in lock-up, drives the output shaft.  A pump supplies fluid by internal central supply passages through the sleeve shaft and output shaft to enter the entrance passage between the turbine and stator to the converter flow-path and exit by an internal central exit passage between the impeller and stator and an outlet passage to a cooler.  The torque converter hydrokinetic axial thrust and bevel gear axial thrust are axially opposed and substantially equal to balance thrust load on the sleeve shaft.  The torque converter transmits all hydrokinetic thrust to the sleeve shaft in a direction toward the bevel gearset and the bevel gearset has left-hand spherical bevel gear teeth to transmit balancing thrust toward the torque converter.

Abstract: METHOD AND MACHINE FOR LOCATING           VARIATIONS IN TENSION IN SAW BLADES     Abstract of the Disclosure A method and machine for locating variations in tension in circular saw blades automatically, to correct uneven distribu-tions of residual stresses, and distortions of the blade surfaces from true planes, so that the blades will run true.  This operation has previously only been performed manually, by highly-skilled craftsmen.  The saw blade is elastically deflected so that its normally-planar surface lies in a curved surface of a predetermined contour.  A proximity sensor passes over the blade to detect deviations of its surface from the predetermined contour, which occur at points of uneven stress distribution or surface distortion.      At such points, the blade may be arrested and hammered until the fault is corrected.
