Abstract: ABSTRACT         A common control for a community office (C.O.) switching system includes two interactive processors.  A call control processor comprises the uppermost element in the con-trol hierarchy and is a stored program processor that controls call progression, marks paths through a matrix switch network, and performs other functions.  A port event processor constructed of "combinatorial logic" is sequentially coupled to every port equipment position connected thereto over a four millisecond scan cycle.  Interaction between the call control processor and the port event processor is effected through a port data store, which provides an individual port data field per port equipment position.  The port event processor also includes timers that respond to call timing information that can be stored in a port data field for controlling the processing of certain signals from the corresponding port equipment position.

Title: Optical system for the detection of  flaws in bottles or the like

Abstract: ABSTRACT OF THE DISCLOSURE     In order to enable a laser beam to scan the complete inside surfaces of an empty bottle or the like, two mirrors oscillating about right angular axes are employed which successively reflect the laser beam.  The oscillations of the two mirrors are correlated to impart an annular or spiral scanning motion to the laser beam.  Subsequently passing through a converging lens, which is focused at the mouth of the bottle being tested, the laser beam enters the bottle for point-by-point scanning all of its sur-faces.  The presence of a flaw in the bottle is sens-ed from the intensity of the laser beam that has penetrated, or has been reflected from, the bottle, as by an integrating sphere and a photoelectric detector mounted in position thereon.  Various other embodi-ments of the invention and modifications are disclosed.

The clutch includes a male cone member carried for rota-tion on an input shaft, and for limited axial sliding movement therealong.  Interconnection between the male cone member and the input shaft is provided by a series of elongated pins carried in recesses formed in the male cone member and in the input shaft.          A female cone member, formed integrally with an output shaft, receives the male cone member for driving engagement   When en-gagement is desired, a fluid pressure piston and thrust plate urge the male cone member axially along the input shaft into driving engagement with the female cone member.  A stop pin carried by the thrust plate engages an abutment for limiting the axial motion of the hydraulic piston and male cone member   When disengagement is desired, fluid pressure is released, and a resilient mechanical device such as a set of springs urges the male cone member out of engagement with the female cone member.          A second mechanical device such as an additional set of springs returns the thrust plate and piston to their deactivated positions.

Abstract: ABSTRACT     A method as described in which a continuous elastic ribbon having a heat-activated adhesive coating on one surface is fed to a diaper web assembly station in a stretched condition.  Simultaneously, discrete absorbent core segments as well as webs of moisture-impervious backsheet material and moisture-pervious topsheet material are fed to the diaper web assembly station.  At the station, the stretched elastic ribbon is adhered to the moisture-impervious backsheet web in discrete areas of the elastic by activating the adhesive at predetermined points along the length of said web.  After the adhesive has set up, the assembled web and the elastic contained therein is severed in its unadhered areas, whereupon the unadhered end portions become relaxed and inactive without affecting the functionality of the adhered portions in the ultimate assemblage.  The inventive concept in its broadest sense relates to the continuous adherence of discrete lengths of stretched elastic to a continuously moving web at relatively high operating speeds and thereafter severing the elastic in the unadhered areas to produce elasticized structures having discrete strands of elastic adhered thereto at predetermined locations along their length.  In a particularly preferred embodiment, the aforementioned process is utilized to apply discrete elastic leg bands to a disposable diaper structure to provide improved containment and fit therein.

Abstract: POSITION DETECTOR FOR A STEPPING MOTOR          ABSTRACT OF THE DISCLOSURE      The invention provides a feed arrangement enabling the detection of the rotor position of a stepping motor in rela-tion to polarity of the motor pulses and to apply a series of long duration pulses should the polarity be considered to be wrong. The detector includes means for sampling the induced voltage generated by the motor at a predetermined moment, the motor being then open circuited, comparing said voltage with a reference signal and using the result of the comparison to determine whether or not the long duration pulses should be applied to the motor. The arrangement is distinguishable from other inventions by the fact that one bases the detection of the rotor stepping not through detecting whether or not the rotor has stepped or whether the load has varied but on the polarity of the rotor pulse relative to the position of the rotor. The proposed arrangement is very reliable since the difference between the induced voltage produced by a correct pulse and the voltage produced by an incorrect pulse is very large. The invention is intended for use with micromotors as used in timepieces.

Abstract: ABSTRACT            Apparatus for monitoring gaseous pollutants (e.g. on a chemical plant) produces two infra-red laser beams having different wave-lengths (one corresponding to an absorption line of the gas to be monitored, the other being a reference) which are modulated with different frequencies or phases, and then combined into a single scanning beam.   The scanning beam is continuously dis-placed angularly so as to scan the area to be monitored.  A portion of the beam is returned to the apparatus by scattering or reflection, and is measured.  By correlating this with the direction of the beam, a plan of the monitored area superimposed with a continuously updated indication of the amount of gas can be displayed e.g. on a VDU.
