Abstract: ABSTRACT     COLOR-PICTURE/MULTICHANNEL-SOUND RECORD           Color picture information is recorded on a video disc together with multiple channels of sound information (e.g., a pair of stereo sound signal components).  Each audio signal to be recorded modulates the frequency of a respectively different sound carrier over a respectively different low frequency deviation range.  Picture carrier waves are frequency modulated in accordance with composite color video signals, including a luminance component and a chrominance component.  The duty cycle of the modulated picture carrier waves is varied in accordance with the sum of the respective frequency modulated sound carriers to form a recording signal,  The sound carrier deviation ranges lie below (but near) the band occupied by the chrominance component.     A disc record is developed with a pattern of depressed and non-depressed regions in its groove bottom representative of the recording signal.  Playback apparatus recovers from the disc record a playback signal of the general form of the recording signal.  Respective bandpass filters, with pass-bands centered about the respective sound carrier deviation ranges, select playback signal portions for application to respective sound carrier FM demodulators.  Additional filter, with passband encompassing picture carrier deviation range and first order sideband therefor, supplies input to picture carrier FM demodulator.  Video signal processing circuits, responsive to output of picture carrier FM demdoulator, include respective comb filters for selectively passing respective luminance and chrominance components.

Abstract: ABSTRACT OF DISCLOSURE           A resilient, thermally bonded, non-woven fibrous batt having a uniform compression modulus in one plane which is more than the compression modulus measured in a direction perpendicular to that plane, and a substantially uniform density across its thick-ness is obtained by preparing a batt comprising at least 20% by weight of crimped and/or crimpable conjugate fibres having or capable of developing a crimp frequency of less than 10 crimps per extended cm. and a decitex in the range of 5 to 30.  The batt is termally bonded by subjecting it to an upward flow of a fluid heated to a temperature sufficient to heat the batt to a temperature in excess of the softening temperature of the lower softening component but below the softening temperature(s) of the other component(s) of the conjugate fibre to effect inter-fibre bonding.  The thermally bonded batt is then cooled by an upward flow of cool air.

Abstract: ABSTRACT OF THE DISCLOSURE   Compositions are provided for the determining of whether or not a female is pregnant.  The compositions consist essentially of a neutral and substantially inert particle (e.g., polystyrene latex) on which   ?-globulin is adsorbed.  The ?-globulin which is so absorbed on the neutral-inert particles, is then coupled to one functional group of a bi-functional coupling agent, the two functional groups thereof possessing different reactivities, (e.g. toluene-2,4-diisocyanate), the other functional group of the coupling agent already being coupled to human chorionic gonadotropin.  A body fluid of the female suspected of being pregnant is mixed with the above composition and is permitted to stand.  Agglutination indicates non-pregnancy, whereas failure of agglutination indicates pregnancy.  This determination takes place within about three minutes.

Abstract: VARIABLE EDGE FADEOUT APPARATUS FOR ELECTROSTATIC REPRODUCTION MACHINES     ABSTRACT OF THE DISCLOSURE            An imaging lens system for electrostatic type reproduction machine or copiers utilizing a zoom lens effective to provide, within the magnification limits of the lens, infinitely variable image sizes.          A control is provided to pre-set the lens to auto-matically give, upon actuation, at least one preselected image size, with an override control to enable the lens to be set to provide any image size regardless of pre-set conditions.          Further controls are provided for the machine non-image erase mechanism to automatically compensate for changes in the image borders brought about by changes in image size due to resetting of the zoom lens.  For this purpose, an infinitely variable edge fadeout apparatus is provided incorporating movable shutters to vary the effective size of the edge erasure slots in correspondence with image size together with timing controls for changing the operational timing of the pitch fadeout lamp in response to changes in image size upon resetting of the zoom lens.  Further controls enable the critical positioning of the image produced by the zoom lens on the photosensitive member to be adjusted to assure that the image, whatever the size, is optimally positioned on the copy produced with other controls to enable the image, whatever the size produced by the zoom lens, to be physically moved or offset on the copy.

Abstract: ABSTRACT OF THE DISCLOSURE             A brake actuator for a vehicle having air brakes is disclosed in which air pressure is expelled through the actuator upon release of the brakes in order to purge the latter of contaminants.  The actuator includes a housing in which a piston reciprocates.  Fluid pressure is admitted to the chamber defined between one side of the piston and the corresponding end of the housing in order to urge the latter in a brake actuating direction. The piston includes a passage extending therethrough to connect the chambers defined between opposite sides of the piston and the corresponding ends of the housing, and a shuttle valve carried within the passage in order to close the passage upon brake application and open the passage to permit fluid com-munication between the chambers upon brake release.  An articulated guide rod is pivotally mounted on the end wall of the housing and extends into the piston to guide the shuttle valve during operation of the actuator.

Abstract: LINE SCAN AREA SIGNATURE DETECTION SYSTEM               ABSTRACT OF THE DISCLOSURE           An area signature detection system arranged to receive an output from a sensor operative in the electromagnetic spectrum, where the output from the sensor is an amplitude varying electrical signal repre-senting the field-of-view beheld by the sensor, and to utilize this high frequency information in such a man-ner that low frequency scene content, necessary for area correlation processing, can be extracted and effectively utilized.  Our invention involves certain highly advantageous techniques for generating area signatures from line scan sensors, and may be applied to cartesian, circular or polar scan formats.  In one particular embodiment or our invention, we describe how orthogonally disposed area signatures can be used to generate area correlation tracking signals that can be used in the derivation of appropriate missile guidance commands.  Our teachings are also useful in providing line-of-sight stabilization for fire control systems, alignment and position errors for landing and hovering control systems, as well as intrusion detection sys-tems.  In the case of a system using a television camera as the sensor, this invention provides a way of obtaining an operator display and system control sig-nals despite the fact that only a single such sensor is used.

The input/output control logic, or channel, of a central processing unit is connected to a plurality of peripheral input/output device control units, in parallel, by a plural line interface bus which includes bidirectional data transfer lines and bidirectional address transfer wires.  The interface bus also includes unidirectional lines to and from peripheral device control units which synchronize operation of use of the bus.  Several forms of I/O communications are shown to be controlled by the interface bus and include, direct processor controlled data transfer with simultaneous transmission of data and commands to peripheral devices, cycle steal data transfers permitting concurrent input/output operations and central processor program instruction execution, and peripheral device initated interrupt requests to the central processor.  A common polling mechanism for selecting one of a plurality of peripheral devices which may be requesting cycle steal use of the bus or interrupt handling use of the bus is disclosed.          During cycle steal data transfers, peripheral device status information can be transferred over the interface bus to the central processor storage without the need for requesting interrupt handling from the central processor.
