Abstract: ABSTRACT OF THE DISCLOSURE      Flame retardant latex bases having an excellent balance of properties are prepared most efficiently and economically by blending together two separately polymerized latexes of different types, the polymeric content of one of said latexes being formed predominantly from a monomer mixture consisting of from about 70 to about 92% by weight vinylidene chloride and 8 to 30% by weight of certain polar comonomers principally of the lower alkyl acrylate class while the polymeric content of the second latex is formed from a monomer mixture consist-ing predominantly of styrene and butadiene.  This technique of producing the desired flame retardant latex bases by combining two separately prepared but simpler component latexes not only maximizes quality control and manufacturing flexibility but also permits the simultaneous realization of higher con-versions and reduced polymerization cycles of residence times so that productivity is also maximized.  Provided the solids contents of the two separately polymerized latexes are fairly close to each other (i.e. somewhere near the usual range of about 40 to 50% by weight), then, latex bases of commercial interest can be formed by blending the vinylidene chloride copolymer latex with from about l/9th to about 4 times its weight of the styrene-butadiene latex so that vinylidene chloride represents from about 20 to 80% by weight of the total polymer content of the resultant blend.

Abstract: RCA 68690 Div. B       ABSTRACT      COLOR-PICTURE/MULTICHANNEL-SOUND RECORDING SYSTEM     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 demodulator, include respective comb filters for selectively passing respective luminance and chrominance components.

Abstract: ABSTRACT          "Improvements Relating To Friction Pad Assemblies For Disc Brakes"         The present specification discloses a friction pad assembly and disc brake incorporating such an assembly, wherein the friction pad assembly comprises a backing plate and a pad of friction material secured thereto, a wire spring being secured to the backing plate.  The wire spring comprises a coiled region from which two arms extend in generally opposite directions.          The coiled region  of the spring is located in a recess in the backing plate with the arms extending from the recess on opposite sides of the backing plate.  Thus the spring arms are the only parts of the spring extraneous to the dimensions of the backing plate so that in a simple manner the optimum amount of design space for constructional strength, is available in a brake incorporating such a friction pad assembly.          Also, by virtue of the spring arms extending one on each side of the backing plate, stable spring biassing of the friction pad assembly is achieved in the brake.

Abstract: SELF-CONTAINED RELOCATABLE MEMORY SUBSYSTEM            Abstract of the Disclosure An apparatus for use as part of a computer system's external memory for storing a subprogram used by the computer and modifying selected data words read from the apparatus prior to transmission to the computer. The apparatus includes an addressable read only memory (ROM) having a word size which is greater than the instruction word size used by the computer.  The apparatus also includes a plurality of base registers which may be loaded under control of the computer's operating system program.  The read only memory contains a software subprogram written assuming it is stored at an absolute location in the computer's memory system other than its actual location.  Each ROM location contains one instruction or word of data and a plurality of non-data bits which may specify one of the plurality of base registers.  As a word is read out of the ROM, a decoding circuit decodes the non-data bits to determine which, if any, of the base registers is specified.  If a base register is specified, the decoding circuit triggers a gating circuit connected to the specified base register.  The triggered gating circuit gates the contents of the specified base register into an adder, the other input to the adder coming from the data bits read from the ROM.  The resulting data word, modified by the addition of the specified base register's contents, is fed into a driver circuit which transmits it to the computer.  If no base register is specified by the non-data bits, the decoder circuit does not trigger any of the gating circuits, and a pattern of all zeros is provided as one input to the adder, the second input being the data bits read from the ROM. In such case, the resulting data word sent to the computer represents the unmodified data bits read out of the ROM.

Abstract: ABSTRACT A roll with controllable bow has a cylindrical inner part and a tubular outer part surrounding the inner part and end-mounted in such a man-ner as to rotate thereon.  Arranged upon the inner part, along a surface line are spaced heater bands.  Arranged in the inner part is at least one elec-trical temperature sensor in the immediate vicinity of the heater band and at least one additional electrical temperature sensor on the side of the inner part remote from the heater bands. The two temperature sensors are connected to a device for measuring the temperature difference and govern?n electrical control circuit to which is connected a heating circuit of the heater band.  Heating of the heater band is controlled in such a manner that a pre-determined temperature difference is maintained between the heated and un-heated sides of the inner part.  The differential longitudinal expansion of the unheated and heated sides of the inner part causes the inner part to bow, and this bow is transferred to the outer part through bearings.  The side of the inner part remote from the heater band may be cooled.

Abstract: ABSTRACT OF THE DISCLOSURE           A deformable polyurethane roller, which may be either a squeegee roller or a blotting roller, is positioned to contact a liquid-developed electrostatic image on a photoconductor.  The polyurethane roller has a resistivity of 109 ohm-centimeters or less and a Shore A hardness of 45 or less.  The roller is biased by a potential having a sign the same as the sign of the charged toner particles in a liquid developer which comprises an insulating liquid having charged toner particles disseminated therethrough.          The bias on the polyurethane roller is such that it prevents streaking, smearing, tailing or distortion of the developed electrostatic image and removes so much of the liquid carrier of the liquid developer from the surface of the photoconductor that the just-moist developed image can be transferred to a carrier sheet. This enables a higher-boiling insulating liquid to be used as the carrier liquid in a liquid developer.  The polyurethane roller is driven so the relative motion between its surface and the surface of the photoconductor is substantially zero. In one form of the invention, the roller is a squeegee roller  in another form of the invention, the roller is a blotting roller formed with closed-cell polyurethane foam formed with open surface pores. Means are provided for squeezing liquid absorbed by the pores from the pores so as to continuously present open dry pores for blotting the liquid from the liquid-developed image.           After development, the developed image can be transferred to a carrier sheet as is known to the art.

A television receiver including a synchro-nizing arrangement for providing line and field drive pulses for line and field output stages, which syn-chronizing arrangement comprises a line oscillator control circuit for controlling the frequency and/or phase of a line oscillator the output signal of which is divided by a divider circuit to produce pulses of field frequency. The divider pulses are applied to a field coincidence stage together with received field synchronizing pulses where their phases are compared and the number of times there is coincidence is count-ed by a counter and to a controllable switch which also receives field synchronizing pulses from a field oscil-lator which is driven by received field synchronizing pulses, A mode selection circuit controls the opera-tion of switch which switch is driven into an inter-nal synchronization mode when coincidence is present in the field coincidence stage for a given period, in which mode divider pulses drive the field output stage, and into an external synchronization mode when the above coincidence is not present, in which mode pulses from the field oscillator drive the field out-put stage, In order to prevent a black bar appearing for a finite period on the display tube of the receiv-ing when changing television channel or the camera is changed in the studio the line oscillator control cir-cuit produces an output which output drives the switch from the internal to the external synchronization mode.
