Abstract: ABSTRACT OF THE DISCLOSURE            This disclosure depicts a CRT (color cathode ray tube) of the shadow mask type, and an improved shadow mask therefor. The CRT has a screen and an electron gun assembly for generating a plurality of electron beams.  The improved shadow mask has a dished perforate central portion for selectively transmitting electrons to the screen.  The mask has a predetermined surface on a peripheral portion of the mask which is so oriented that when the mask is in place in an operating tube there results an undesirable specular electron reflection of overscanned electrons off the exposed surface and a visible electron flooding of the screen near its perimeter.  The shadow mask is characterized by having on the said surface an array of close-spaced grooves oriented to scatter a major fraction of reflected overscanned electrons away from the screen and to thereby markedly suppress the said visible electron flooding of said screen.

Abstract: D-21,850 METHOD AND APPARATUS FOR CONVERTING BINARY   by Adam Lender ABSTRACT OF THE DISCLOSURE     A transmitter converts an incoming bit stream into a single-sideband signal for transmission over a band-limited channel such as a digital radio.  The incoming bit stream is digitally processed to obtain both in-phase and quadrature-phase 3-level correlative signals.  The two correlative signals are separately band limited to a passband having a bandwidth that is about one-fourth the bit rate of the original bit stream, and these band-limited signals are then separately analog modulated, respectively, using in-phase and quadrature-phase carrier frequen-cies which are derived from a carrier oscillator.  The products from the analog modulation process are then combined in a summing circuit to derive the single-sideband signal.  At the receiver, the single-sideband signal is analog demodulated using a carrier frequency that is at either end of the single-sideband frequency spectrum,i.e., C?1/4T  Hz where C is the carrier, frequency in Hz and 1/T is the cut-off frequency in Hz and is numerically equal to the bit rate in bits per second (BPS).  The lower sideband is selected by a low-pass filter and the signal thus obtained is modified duobinary.  By rectifying and slicing the modified duobinary signal the original data is recovered.

Abstract: METHOD AND APPARATUS FOR MOVEMENT OF HEATED THERMOPLASTIC ELEMENTS FOR SHEAR-FUSION BONDING OF SUCH THERMOPLASTIC ELEMENTS              Abstract A shear-fusion bond method is provided to create a direct fusion joinder or bond over an extended interface between like thermoplastic elastomeric elements of a block copolymer having a rubber-like center or mid-block and styrene end blocks.  Such material has a high melt viscosity and does not readily flow.  The interface surfaces are coupled to a heat source and heated to a fusion bonding temperature, thereby softening the interface material so that it flows under pres-sure.  The elements, with the surfaces in pressurized engage-ment, are rotated relative to each other about an axis which is normal to the interface.  Rotation is through an angle of at least 10 degrees to subject the softened interface material to a high rate shear force movement substantially in the plane of the interface.  This decreases the viscosity and causes the interface material to bondably flow.  The interface surfaces are firmly held together while in the bondably flowing state to create a shear-fusion bond in which the interface disappears.  The surfaces may be separately heated on a hot platen and then located in abutting engage-ment for rotation.  The surfaces may also be provided with appropriate heat generating particles.  The surfaces are inductively heated from a suitable field source to soften the interface, and then rotated.

Abstract: ABSTRACT OF THE DISCLOSURE        A fabric is stretched across a sign framework to serve as a display face.  Forming the framework are upper, lower and respective side support elements.  Depending upon the particular version, a hinge or saddle is affixed to one or more of the sup-port elements.  A hinge pin tensioner has limited rotation and is coupled to a marginal portion of the fabric.  In some versions, such hinge assemblies are included along more than one side of the framework.  In others, different fasteners are employed along some of the support elements.  In one particular approach, the fabric is stretched directly across a separate frame that, in turn, is hinged along a support element of the main framework, so that the frame may be swung away for the purpose of obtaining access to the interior of the main framework that usually encloses a source of illumination.  At least almost every different component of the assembly is especially shaped and dimensioned so as to enable it to perform a plurality of different functions or tasks, thereby reducing the total number of components involved and the cost of assembly and installation.

Abstract: SELF-TIGHTENING KEYLESS CHUCK                    ABSTRACT OF THE DISCLOSURE           A bi-directional, self-tightening drill chuck suited for surgical and other medical applications in accordance with the present invention includes a chuck body having an internally tapered opening at one end that is defined by first and second cam surfaces and a central, longitudinally extending cannula or passage formed through the length of the chuck body.  A plurality of tapered gripping rollers are located within the opening and are resiliently urged against the cam surfaces throughout a range of adjust-ment by a spring retainer which includes rearwardly extend-ing spring arms.  A control sleeve is adjustably mounted on the chuck body and includes a thrust bearing at one end for contacting the forwardly facing ends of the tapered rollers and a split retainer assembly at its other end for contacting the rearwardly extending ends of the spring arms such that the tapered rollers and the spring retainer move as a unit relative to the chuck body when the control sleeve is adjusted to cause the tapered rollers to grip a selected tool bit.          The chuck can accept a tool bit, such as a common twist drill, or other implements at one end through a tool receiving opening formed in the control sleeve or from the opposite end through the cannula.  In operation, the torque transmitted through the chuck causes the tapered rollers to shift circumfer-entially relative to the cam surfaces and proportionally increase the gripping force applied to the tool bit.

Abstract: ABSTRACT OF THE DISCLOSURE          An improved method for producing hydrogen fluoride from fluoride bearing ores, such as fluorospar and fluorapatite, by reaction of the ore as a slurry in fluorosulfonic acid.  The slurry is heated by the exothermic heat of the reactor to vaporize volatile phosphorous compounds and substantial quantities of hydrogen fluoride.  The calcium fluoride is substantially reacted to form hydrogen fluoride.  High silica fluorospar ores can be used since silicon tetrafluoride is not formed with fluoro-sulfonic acid.  Another feature provides for addition of calcium fluoride to the slurry to react with the by-product sulfuric acid in the residual solids to eliminate the sulfuric acid recovery step in the process.  Hydrogen fluoride produced is recovered, together with the hydrogen fluoride produced from the hydrolysis or pyrolysis of the intermediate fluorophos-phorous compounds.  Additionally, at least a portion of the hydrogen fluoride can be reacted with sulfur trioxide to form fluorosulfonic acid for makeup in the process.
