Abstract: ELECTRONIC APPARATUS FOR CONVERTING DIGITAL       IMAGE OR GRAPHICS DATA TO COLOR    VIDEO DISPLAY FORMATS AND      METHOD THEREFOR        ABSTRACT         A digital video color signal generation system for converting image or graphics data into a color video display format transforms source image or graphics data into a single data word comprising three separate groups of data bits which define the video display to be produced in terms of intensity, hue and saturation character-istics, and stores such data bit groups in respec-tively corresponding fields in a memory to allow independent user control of one or more of such characteristics.  The data bit groups correspond-ing to hue and saturation are employed for simul-taneously addressing storage locations in memory devices which contain digital color reference data representing symmetrically mapped combinations of hue and saturation values, which data are read-out and delivered to respectively associated multiply-ing digital-to-analog converters or producing red, blue and green color video signals.  The group of data bits corresponding to intensity are directly converted to analog signals which are employed to control the reference voltage input of each of the multiplying digital-to-analog con-verters in a manner which modulates the magnitude of each of the video signals to permit varying the intensity of the resulting video display without also altering either of the hue or saturation.

Abstract: BUILDING AND SHAPING A TIRE              Abstract of the Disclosure A flat cylindrical carcass band is built on a cylindrical surface provided by a unique shaping means and abutting turnup means.  The shaping means has inner and outer walls the ends of which are juxtaposed solid elastomeric end rings so as to form an annular envelope. The outer wall has between its inner and outer layers an arrangement of spring blades of particular shape formed to control the toroidal shape of the expanded outer wall to a precisely determined contour.  The turnup means each include an inner and an outer bladder the edges of each being also juxtaposed solid elastomeric end rings. The end rings of each turnup means are seated with the associated end rings of the shaping means in a common retaining groove formed in a circumferential set of radially extendable segments which expand the end rings and the overlying carcass to conform the carcass initially about prelocated bead cores.  To conform the carcass about the bead cores before fully shaping the carcass toroidally, the shaping means has also a pair of inner bladders each having a solid elastomeric ring interfitting respectively with and between the end rings of the mentioned envelope.  These latter inner bladders cooperate on inflation to roll the carcass band lying close to the respective beads outwardly and to compact the bead region, and thereafter the shaping means envelope is inflated to shape the carcass between the bead regions and the outer bladder of the turnup means is inflated to extend the turnup, and optionally, to apply sidewall material.

The loudspeaker telephone apparatus consists of a hybrid circuit which interconnects a telephone line and its line balance impedance with receive and transmit ampli-fiers.  These amplifiers are connected to a bridge circuit, the arms of which are formed from two pairs of similar coil groups located in two multi-filar moving coil loudspeakers.          The coil groups in one loudspeaker are connected in series aiding while the coil groups in the other loudspeaker are connected in series bucking.  In one arrangement, the bridge circuit may be connected directly to the amplifier, the receive amplifier being connected across the pair of coils in each loudspeaker and the transmit amplifier being connected across the junction between the pair of coils in each loudspeaker.  In another arrangement, a second hybrid circuit is used to connect the bridge to the amplifiers which are connected in the hybrid by its amplifier terminals.  One coil group in the bridge is connected to the line terminals of the hybrid and a balance RC impedance is connected to the balance terminals.

Abstract: ABSTRACT OF THE DISCLOSURE         A fabric part label feed apparatus is described which includes a tape strip consisting of discrete individual labels joined end to end.   The apparatus further comprises a storage device for the strip and means for removing the tape strip from the storage means.  There is a sewing station and a supporting and feeding device directing the tape strip to the sewing station.  A feed roll is arranged for reciprocating movement towards and away from the supporting and guiding means.  Intermediate each of the labels are engagement means for engagement with the feed rod.  The strip is received adjacent to the sewing station and a label is then fed therefrom into and through the sewing station.  A cutting means operates in conjunction with the label feed rod to sever individual labels from the strip immediately prior to an individual label being fed into the sewing station.  The advance in the art is in that the incremental movement of the tape is precisely controlled in co-operation with cutting means for separating individual labels from the tape strip.

A light-transmitting cover panel (28) is attached to the housing member for enclosing the flashlamps, and the circuit strip extends beyond the cover panel to expose connecting terminals.  The lamps have tubular envelopes and are positioned with their longitudinal axes substantially parallel to the printed circuit strip and arranged in substantially coaxial alignment.  The housing member includes ledges (44 and 46) within the channel for spacing the printed circuit strip from the rear wall (40), and the sidewalls of the channel have guide ribs (54 and 56) for engaging notches (50 and 52) in the circuit strip for facilitating assembly and location and avoiding longitudinal shifting of the strip.  The housing member further includes reflector cavities (11, 11', etc.) adjacent to the lamps, and a continuous coating of electrically conductive reflective material (42) covers the surfaces of the channel and reflector cavities for providing both reflective surfaces for flashing lamps and a shield to reduce the likelihood of accidental flashing of lamps by electrostatic charges. In a preferred embodiment, the unit has connector terminals at opposite ends, and the linear array of flashlamps is divided into two groups disposed in opposite halves of the unit, each group of lamps being operated by the connector terminals (20, 22 and 20', 22') at the remote end so as to reduce the red-eye photographic effect.
