Abstract: For use in a beam index color cathode ray tube (CRT), a multi-beam group electron gun directs first and second groups of vertically aligned electron beams on respective parallel, horizontally aligned color phosphor stripes on the CRT's display screen. Each group of electron beams includes three beams, one for each of the three primary colors of red, green and blue. The first and second electron beam groups are horizontally offset from one another, with the upper, intermediate and lower electron beams in each group tracing the same horizontal phosphor stripe as the beams scan the display screen and with a time delay provided to synchronize the video information of both electron beam groups. A color video signal is provided either to a respective cathode or to a respective segmented conductive portion containing a beam passing aperture in the electron gun's G1 control grid for individually modulating each beam with color video image information.

Abstract: A new process of preparing potassium sulfate fertilizer and other metal sulfates from the chlorides and other halides of these metals. The process utilizes the discovery that sulfur dioxide or trioxide, when introduced as a fluidizing medium into shallow beds of the halide salts at moderately elevated temperatures (1000° F.-1150° F.) in a counter current process results in the conversion of the metal halides into metal sulfates and the halide gas. The process is carried out in a series of true fluidized beds preferably but not necessarily arranged in a vertical configuration so that the solids flow downward due to the fluidized process and the sulfur dioxide or trioxide gases flow counter currently in an upward direction producing pure metal sulfates at the bottom and pure halide gas at the top.

Abstract: A dispenser for selectively dispensing first and second rolls of sheet material respectively wrapped around first and second cores is provided. The dispenser includes a housing defining a storage compartment for the first and second rolls and an opening, a first and second core support structures disposed in the housing for respectively supporting differently sized first and second cores and a divider slidably carried by the housing and covering a portion of the opening. The divider is movable between a first dispensing position, wherein a first portion of the opening is uncovered to allow access to the first roll and a second portion of the opening is covered to prevent access to the second roll, and a second position, wherein the first portion of the opening is covered and the second portion the opening is uncovered to allow access to the second roll.

Abstract: A cathode for use in an electron gun includes a base metal comprising Ni as a principal component and a two-layer electron emissive material disposed on the base metal. The inner layer is comprised of an alkaline earth metal oxide and 1-30 wt. % W and may further include 0.1-5 wt. % of a rare earth metal oxide. The outer layer is comprised of an alkaline earth metal oxide and may further include 0.1-5 wt. % of a rare earth metal oxide. The outer electron emissive layer provides stability for the cathode. In the degassing and activation process, W and Ni react at high temperatures to form a Ni4W fine crystal structure. An intermediate layer, such as Ba2SiO4, is dispersed in the Ni4W fine crystal structure in operation. Free barium is produced in reactions between the various cathode components to provide a high current density for the cathode. The normalized electron emission current value of the cathode does not decrease with use, even over extended periods of operation.

Abstract: In an Internet protocol (IP)-based multimedia system having a voice over packet infrastructure call handling involves the execution of a call processing program that controls state transitions in a finite state machine termed the “call model.” These transitions are representative of the events that occur during the lifetime of the call and result in the execution of pre-defined actions. In order to provide high level Intelligent Network (IN) capabilities to IP end-point subscribers, a call model layer implements the IN call model, but is closely integrated with the IP-based, multimedia call model that runs within the base platform. The integration employs a precisely defined state-level map between states in the IN call model and the corresponding states in the base call model. The IN call model layer is thus able to support access to IN components to permit the existing base of IN services to be easily accessed and to permit the base layer to support client-level interaction and event handling.

Abstract: A method of depositing a biaxially textured metal oxide on a substrate defining a plane in which metal oxide atoms are vaporized from a source to form a plume of metal oxide atoms. Atoms in the plume disposed at a selected angle in a predetermined range of angles to the plane of the substrate are allowed to contact the substrate while preventing atoms outside a selected angle from reaching the substrate. The preferred range of angles is 40°-70° and the preferred angle is 60°±5°. A moving substrate is disclosed.

Abstract: A system and process for recycling shredder residue, in which separating any polyurethane foam materials are first separated. Then separate a fines fraction of less than about ¼ inch leaving a plastics-rich fraction. Thereafter, the plastics rich fraction is sequentially contacted with a series of solvents beginning with one or more of hexane or an alcohol to remove automotive fluids; acetone to remove ABS; one or more of EDC, THF or a ketone having a boiling point of not greater than about 125° C. to remove PVC; and one or more of xylene or toluene to remove polypropylene and polyethylene. The solvents are recovered and recycled.

Abstract: In a cellular telephone system, as the strength of the signal between a cell site and a mobile unit weakens in the absence of another cell site to hand off the mobile unit to, the mobile unit user is warned of the impending loss of the call before it occurs. This allows the user sufficient time to take precautionary steps such as moving or re-orienting the hand-held mobile unit to compensate for the loss of signal strength and maintain integrity of the communications link. The mobile unit user is warned of a signal level reduction below a predetermined threshold by means of an audible tone emitted by the mobile unit's earpiece prior to loss of a call in progress.

Abstract: Adsorption of molecules onto a thin metallic surface such as of gold, silver or copper is measured by surface plasmon resonance (SPR) using Fourier Transform (FT) spectroscopy. Reflectance spectra from a prism/metallic film sample surface at a fixed angle of incidence is measured with FT spectroscopy. The reflectance spectrum exhibits a pronounced minimum due to the SPR effect, which can be shifted by changing the angle of incidence or metallic film thickness. The position of the reflectance minimum shifts in wavelength with the adsorption of molecules onto the gold surface due to a change in the index of refraction at the interface. The FT-SPR sensor instrument provides wavelength stability and reproducibility of the resonance wavelength to permit detection of small wavelength shifts, and also substantially increases the spectral range over which the SPR measurements can be made.

Abstract: A gauge wheel/coulter arrangement for an agricultural row unit. A pair of closely spaced, narrow, ground-engaging wheels in side-by-side relation are mounted to rotate about intersecting axes. Specifically, the wheels are angled inwardly toward each other at the forward and lower portions of the wheels so that adjacent edges of the wheels firmly engage each other to cause the wheels to rotate in unison when drawn through a field. The region of contact between the wheels extends from a point at or below the horizontal center lines of the two wheels, downwardly and rearwardly to a point adjacent where the two wheels engage the ground. A coulter is located between the gauge wheels and bisects the angle between them. The gauge wheels engage and pin down the crop residue while the coulter cuts the residue as it is held in place and tensioned by the passing, diverging gauge wheels.

Abstract: An agricultural planting machine having a frame, a pair of opposite furrow forming disks rotatably mounted on the frame on intersecting axes and a pair of gauge wheel assemblies mounted on the frame respectively adjacent the opposite sides of the pair of furrow forming disks. An improved mechanism for adjustably mounting the other end of each gauge wheel arm which has an internally threaded bore to the frame includes an internally threaded cylindrical shaft mounted on the frame. An externally threaded bushing is rotatably mounted on the shaft for engagement with the internally threaded bore in the gauge wheel arm such that rotation of the bushing with respect to the gauge wheel arm moves the gauge wheel arm axially of the internally threaded cylindrical shaft to adjust the lateral spacing of the gauge wheel from the adjacent disk. A locking member locks the externally threaded bushing to the other end of the gauge wheel arm to cause rotation of the bushing and the arm as a unit.
