Abstract: COLOR TELEVISION CAMERA            ABSTRACT OF THE DISCLOSURE         A color television camera of phase-split type is disclosed wherein an index signal derived by horizontal-ly scanning an index-generating section, produced at the beginning or end portion of vertical scan for an image pickup tube, is converted to a low-frequency signal by a frequency converter so that a low-frequency index signal in at least one horizontal scan period is written into a memory circuit, and the low-frequency index signal is read out for each horizontal scan to produce a standard color television signal from two color-difference signals.          The two color difference signals are derived by processing a modulated color signal, which has been space-modulated by a stripe filter disposed in front of the image pickup tube, and a low-frequency signal or a brightness signal derived from the image pickup tube.

Abstract: ABSTRACT OF THE DISCLOSURE           Brassiere tapes having a body portion and a pair of overlapping tabs extending outwardly therefrom are manufactured by providing a continuous strip of the tape material having elements spaced therealong and layers at least in the body portion forming part thereof.  The material is weldable with ultrasonic vibratory energy, and the tabs are separated physically from each other while simultaneously maintained in acoustical energy coupling relation to each other, such that the individual layers of material in the strip are welded to-gether across the body portion of a tape defined thereby and the tabs are individually welded along an edge but not welded together when interposed between an ultrasonically vibrating horn and an anvil.  The strip is advanced on an intermitten basis between the horn and the anvil by the elements for con-tinuously producing tapes having a desired number of elements thereon.  The separating of the tabs is obtained by interposing an insulation element of material characterized in that it does not bond to the material under ultrasonic vibration but simul-taneously permits the vibratory energy to be transmitted there-through.

Abstract: MULTICOLOR GAS DISCHARGE DISPLAY MEMORY PANEL          Abstract of the Disclosure Gas display panel performance with improved resolution, color, memory margin and brightness is provided as a result of helium based mixtures in a panel structure using evaporated glass tech-nology, e.g., borosilicate glass technology.  Multicolor emissions are achieved directly from the helium based mixtures, and addition-al color enhancement and selection is accomplished by varying the gas parameters of pressure and dopant concentration and the sustain voltage waveform drive conditions.  Color selection from the helium based mixtures with molecular dopants is made using an optical fil-ter or a colored glass substrate.  A gas panel is obtained that emits white light using a helium based mixture doped with oxygen.  It is a Penning mixture with optical radiation in the visible part of the spectrum due to systems of emission bands from the ionized oxygen molecules.  The first negative system exhibits four strong bands that vary from 75 to 125.ANG. in width and account for green, yellow and red colors.  In addition, four weaker bands are observed for the second negative system which account for the blue color.

Abstract: ABSTRACT OF THE DISCLOSURE           A porous acoustic element is disclosed having a con-figuration comprised of individual cross-wound porous layers of widely varying porosity, with transition plenum layers interposed therebetween having a configuration so as to prevent formation of blockages and small area openings which would be created by a direct overlay winding of differing pitch.  The porosity of each wound layer increases in successive layers to compensate for expansion of the gas as it flows through the element.  The resulting porous element allows gaseous flow therethrough, with maximum pressure energy dissipation and controlled velocity to minimize aerodynamic noise created by flow through valves and other flow restrictions.  A specific embodiment is disclosed in which the porous layers are created by variable pitch wire ribbon cross windings and the transition layers are provided by wire mesh having relatively large openings.
