Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus is provided for monitoring the output of a fiber cutter arranged to cut long fiber roving strands into short clippings and to feed the clippings into a slurry-containing mixer, the monitoring apparatus having a plurality of rotatable mounted assemblies each comprising a rotating shaft and a plurality of arms mounted thereon. During normal operation the fiber clippings fall through the moving arms and into an apparatus wherein the fibers are mixed into a slurry, such as a calcined gypsum slurry.  Malfunction of the cutting apparatus resulting in the discharge of long fiber strands causes entanglement of the fiber strands with the moving arms, thereby causing rotation of the assemblies to discontinue and actuating an alarm and automatic switches, thereby rendering the entire apparatus inoperative and preventing serious entanglement of the mixing and conveying apparatus which could result in long shut-down periods.

Abstract: ABSTRACT     A circuit for sensing closed and open states of an electrical contact pair in a monitoring station.  The circuit includes a pulse generator for generating sampling pulses, a galvanic isolator, and an energy storage circuitry and the contact pair in series for allowing the pulse generator to apply the sampling pulses to the storage circuit via the galvanic isolator.  The storage circuit stores enough charges to build a DC voltage of a certain magnitude using the sampling pulses, when the contact pair is open, and discharges the stored charge through the contact pair to the ground and allows the sampling pulses to go to the ground via the galvanic isolator and the storage circuitry, when the contact pair is and remains closed.  The sensing circuit also includes an output circuitry coupled to the galvanic isolator for sensing the pulses being transmitted through the isolator and providing an output signal indicative of the open or closed state of the contact pair.

Abstract: RCA 68,949 DEFECT DETECTION SYSTEM             Abstract of the Disclosure Defect detection apparatus, for optically inspect-ing a spiral groove of a video disc record, directs a coherent light beam at the grooved surface of the disc.  The incident beam, focused at a point beyond the disc surface, illuminates the grooved surface with a light spot that spans a plurality of convolutions of the groove.  Relative motion is established between the disc surface and the incident beam in a manner causing the illuminating spot to rapidly scan the grooved surfaces in a coarse spiral pattern.  The structure of the illuminated groove convolutions, absent any defects, serves as a diffraction grating for diffracting the light into an undeviated zero diffraction order cone of light that converges at a first location in a plane spaced from the disc surface and into deviated higher diffraction order cones of light that converge at additional locations in said plane separated from the first location.  A photodetector is positioned to be in registry with the first location and spaced from said additional locations.  A blocking means is placed over a central region of the photodetector to normally intercept the zero diffraction order light, thereby preventing the conversion of light energy to electric energy by the photo-detector when defect-free groove regions are illuminated.          When a defect exists in the illuminated region of the groove, unblocked regions of the photodetector receive light and the photodetector produces electrical signals indicative of the presence of a defect. A servo means, responsive to departures of the zero order cone axis from a desired orien-tation, is employed for controlling the orientation of the axis of the incident beam to oppose such departures, in order to preclude false defect indications due to warpage or unevenness of the disc record.

Abstract: ABSTRACT OF THE DISCLOSURE             A circuit for controlling the rendering conductive of the controlled rectifiers of a power conversion unit to thereby control the power supplied to a load from a source of alternating current voltage employs a single sense device to sense a prescribed phase relationship between adjacent phase to neutral voltage of the source which is utilized to develop a digital count representing a time-phase relation-ship with respect to the point determined. The digital count thus developed is supplied to a memory system to address that system and based upon the contents of the locations within the memory system thus addressed there is provided an output which determines the time and firing sequence of the rectifiers of the power conversion system. This output is then utilized to generate suitable signals which are applied to the rectifiers of the power conversion system to thereby control the power supplied to the load.

An input shaft extends into the housing and has a pinion gear rigidly affixed to an inner portion thereof.  The pinion gear is adapted to drive the differential and planetary gear assemblies.  Two pinion bearing assemblies are positioned within a bore in the housing through which the input shaft extends.  The pinion bearings operatively support the rotatable input shaft.  A generally flat and annular baffle is rigidly affixed to the inner portion of the input shaft between the pinion bearings and the pinion gear.  The baffle, the innermost pinion bearing, and a portion of the housing define a lubricant  pump chamber for pressurizing and pumping lubricant.  The housing further comprises a lubricant passageway having an inlet in communication with the lubricant pump chamber and positioned between the pinion bearings and the baffle, and an outlet adjacent the differential gear assembly.          Means are provided for circulating lubricant from the differ-ential gears to an area adjacent the pinion bearings, which are adapted for pumping the lubricant into the lubricant pump chamber and against the rotatable baffle.  In operation the rotating baffle creates a lubricant pressure head within the lubricant pump chamber and at the inlet of the lubricant passageway which induces rapid circulation of lubricant through the housing.
