Abstract: ABSTRACT OF THE DISCLOSURE                This invention relates to an improvement in a video signal playback device which derives video signals from an information track on a video disc using a light beam source for impinging upon an information track on the surface of the video disc.  In prior art devices of this type, the circuitry necessary to sense whether or not a light beam is on or off track is rather complicated, since it has been necessary to have at least two sensors (and in some instances three sensors), together with the associated electronics to perform the necessary feedback function for maintaining accurate tracking of the reading beam as the reader and disc move relative to one another radially of the disc.  The present invention overcomes this difficulty by providing a simplified single beam tracking system including circuitry which is responsive to the position of the impinging light beam relative to a prescribed edge portion of the informa-tion track.  When the light beam impinges the prescribed edge portion of the track, the output from the circuitry is nil.      The circuitry provides an output voltage having a first polarity when the light beam impinges less than the prescribed edge portion, and a second polarity when the light beam impinges more than the prescribed edge portion.  When the output voltage signal is applied to the tracking control device, a closed loop tracking system results, accurately keeping the light beam impinging on the prescribed edge portion of the track.

Title: Electromagnetic actuator with torque-compensating  poles

Abstract: Abstract of The Disclosure An electromagnetic actuator has a stator and an armature both made of magnetically permeable material and each having a plurality of projecting poles spaced apart from each other.  The armature poles and stator poles cooperate with each other so that each pair of opposed pole faces of an armature pole and a stator pole form a narrow working air gap for passing magnetic flux between the opposed pole faces.  An electrically energizable coil produces magnetic flux which passes through the poles of the armature and stator and across the working air gaps.  Selected pairs of the opposed armature and stator poles form a substantially constant air gap so that the attracting magnetic force on the armature increases as the armature moves in a first direction relative to the stator and decreases as the armature moves in the opposite direction, and other pairs of the opposed armature and stator poles form a variable air gap so that the attracting magnetic force on the armature decreases as the armature moves in the first direction and increases as the armature moves in the opposite direction.

Abstract: Abstract of the Disclosure Microcapsules having a core of an alkaloidal material surrounded by a protective cross-linked polymeric wall are dis-closed.  The microcapsules are produced by intermixing a poly-meric wall material with a liquid vehicle to form a solution thereof as a continuous first phase, and mixing the solution with an alkaloidal material.  ?he produced admixture is agitated to disperse the alkaloidal material as a plurality of discrete minute core material entities in the first phase, and thereafter, phase separation is induced to separate the polymeric wall mate-rial from the liquid vehicle so that the wall material forms embryonic sheaths about the core material entities.  The poly-meric wall material is then cross-linked to form protective walls around each of the core material entities.

There results a bearing aperture having an axial length greater than the starting thickness of the sheet material, and consequently a larger bearing surface inte-grally formed locally in the sheet material.  Apparatus for forming the bearing aperture is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is a stepping motor control utilizing a microprocessor.  The control is suitable for driving one or more stepping motors one at a time or in unison.  In the illustrated embodiment when plural motors are driven together they are driven at the same rate although several of the fea-tures of the invention are suitable for use in circuits pro-viding contouring control;  i.e., where separate motors are driven at separate stepping rates proportional to the relative distances each is to traverse for a single movement.  An acceleration/deceleration circuit is utilized which provides simple yet highly accurate and efficient control of the step-ping motors.  Feed rate compensation for simultaneous drive of two motors is provided.  Also a means is provided to allow stepping rates in excess of the counting rate capability of the microprocessor.
