摘要： A wash additive combination is provided which is loaded into a washing machine at the start of a wash cycle, and which releases a wash additive, such as a fabric softener, into the rinse solution. The combination comprises a wash additive packet of a foam substrate material having a first and a second stable conformation of differing surface area, and a wash additive deposited thereon. A dispenser is provided for mounting atop a washing machine agitator, and into which the packet may be releasably placed, after arranging the packet in its lesser surface area conformation. The packet is retained by the dispenser during initial phases of the wash cycle, and ejected during the spin phase, whereupon it regains its greater surface area conformation for rapid and complete dispersion of active. Embodiments are provided for dual, sequential release of active in the rinse and the dryer.

摘要： A cathode-ray tube comprising in an evacuated envelope an electron gun for generating at least one electron beam which is focused on a display screen to form a spot and which is deflected in two mutually perpendicular directions so that a raster is written on the display screen. The electron gun comprises a cathode which is centered on an axis, a first grid at some distance therefrom along the axis and a second grid at some distance from the first grid, the first and second grids each having a part which is perpendicular to the axis and which comprises an aperture around the axis. The aperture in the first grid, on the side of the second grid, is elongate in a direction coinciding with one of the deflection directions and, on the side of the cathode, is elongate in a direction perpendicular to the elongate direction of the aperture on the side of the second grid. The dimensions and the depths of the portions of the aperture on the side of the second grid and on the side of the cathode are chosen so that, for the beam operating current range of the cathode-ray tube, substantially one cross-over is formed in an astigmatically-focused electron beam, thereby improving near the second grid, spot quality.

摘要： An apparatus and method for syntactic signal analysis which is suitable for processing signals which deviate, within a freely selected margin, from a set of signals predetermined by a grammar, the apparatus being provided with a feature unification mechanism which detects violations of features, and an adaptive threshold mechanism coupled thereto. The feature unification mechanism, which processes the features in groups so that rapid processing is obtained, determines a violation score, thus providing a measure of the deviation of the analyzed signal from the set of signals predetermined by the grammar and indicates what elements of the signal are not satisfactory so that these can be corrected if necessary. The adaptive threshold mechanism enables a number of analyses to be delivered each having a violation score, so that on the basis thereof, in combination with other factors which may be available, it is possible to select the best analysis. The apparatus is applicable to signal correction, signal verification and signal recognition.

摘要： In a color display tube including an electron gun system for producing three electron beams situated with their axes in one plane, coincides to the said plane, curved field shapers 27, 28 are provided at the end of the system. Each field shaper comprises at least three plates of ferromagnetic material. The plates are situated symmetrically with resepect to the plane and the central beam axis, and the curved field shapers face the three beams with their concave sides. The field shapers make the edge field of the frame deflection field pin-cushion-shaped. Each field shaper comprises at least two circumferentially-spaced plates and slots 35, 36 between the plates are covered by plates 31, 34, so that at least one magnetic shunt is formed in each field shaper. The line deflection field is attenuated less and a field disturbance at the area of the electron beams is prevented.

摘要： The spot quality of an electron beam produced by an electron gun in a cathode ray tube is improved by optimizing the dimensions of a beam-forming, apertured electrode arrangement in the gun. This arrangement includes electrodes for forming a cross-over followed by, in the direction of propagation of the electron beam, first and second lens electrodes centered around an axis, for defining an accelerating and prefocusing lens and at least two lens electrodes for defining a main focusing lens. The diameter of the aperture in the second lens electrode is smaller than twice the diameter of the aperture in the first lens electrode, and the effective spacing S-eff between the first and the second lens electrodes is smaller than 1 mm. S-eff is defined as the minimum of the function ##EQU1## where .DELTA.V is the operating voltage difference between the second and first lens electrodes andE(z) is the operating electrical field strength between the first and second lens electrodes on the beam (z) axis as a function of the place z on the axis.
