Abstract: PHN 10.896                 9              20.6.1984 ABSTRACT: Display tube.     A display tube comprising in an evacuated en-velope (1) an electron gun system (6) for generating and focusing by means of a focusing lens at least two elec-tron beams (28 to 35) on a display screen (5), which electron beams are deflected by deflection means and des-cribe a frame on the display screen. The electron gun system (6) comprises at least two electron sources (20 to 26) the electrons of which in each electron beam are accelerated immediately after the electron source by means of an electric field having a field strength exceeding 600 V/mm, the central paths (36) of the electron beams extending substantially parallel to each other, all beams being converged by the focusing lens in or in the immediate proximity of the focus of the focusing lens, after which each separate beam is focused on the display screen by the focusing lens to form a spot also in the case of deflection by the deflection means. The astigma-tism and the coma of the focusing lens, especially for objects not situated on the axis, decreases rapidly with decreasing object potential with the beam aperture angle being kept the same. The electrons leaving the source at a low potential are then accelerated in a strong electric field exceeding 600 V/mm. In this manner, nearly imme-diately after the electrons have left the electron source, a very slim electron beam is obtained which maintains its slimness up to the display screen. The effect of the field curvature of the focusing lens is also considerably reduced by said slim beams. If all electron beams through the focusing lens converge in or in the immediate proximity of the focus of the focusing lens, a minimum of aberrations as a result of the deflection is obtained. The electron sour-ces are preferably P-N cathodes or diode electron guns.

Abstract: IMPROVED SQUARE ROOT CIRCUIT          Abstract of the Disclosure In a telephone signalling detector of the cross-correlation type, samples from a selected communications channel are multiplied with sine and cosine coefficients of different frequencies.  The resulting sine and cosine products for each frequency are separately accumulated over a period of time after which the accumulated results are each squared and then summed for the individual frequencies. A series of sums of squares is compared in accordance with predetermined tone detection parameters to determine the presence or absence of a signalling tone defined by the coefficients.  In a telephone signalling detector intended to detect any of a large family of specified signalling tones in any of a plurality of channels, the square root value of each of the sums of squares is typically provided by digital circuitry for subsequent use in a processor which is operated to complete the tone detection function in accordance with program instructions.  A cost reduced square root circuit provides the square root values from a look-up ROM (read-only-memory) on a prompt and regular basis.  In the square root circuit a large sum of squares is shifted toward lesser significance and a smaller sum of squares is shifted toward greater significance by means of a logic controlled shift register.  Thereafter only a central portion of the shift register content is used along with a corresponding shift record to periodically address the look-up ROM.                             - i -

Abstract: ABSTRACT A multi-direction time division multiplex communication apparatus for a central station in a multi-direction time division multiplex communication system in which the central station transmits signals meant for each of satellite stations in a time division multiplex broadcast mode, while each of the satellite stations after extraction of a clock extracts the signal meant for the own station and intermittently transmits signals from the own station after adjusting the signals to such a timing that, when the signals from the own station reach the satellite station, the signals do not overlap with signals reaching the central station from the other satellite stations and appear as orderly as a single sequence of time division multiplex signals. Despite any fluctuation of an absolute delay time which may occur during communication between the central and satellite stations due to variations in the ambient conditions, the central station selects the output of a particular code regenerator circuit which is operating responsive to a decision clock whose timing matches with the fluctuation, thereby allowing the system as a whole to hold a communication without having the error rate increased.

Abstract: GRATE FOR USE IN INDUSTRIAL FURNACES             ABSTRACT OF THE DISCLOSURE         The grate of an industrial furnace is assembled of elongated grate bars which form rows of neighboring grate bars and the grate bars of neighboring rows partially overlap each other. Each grate bar has a top wall, a front end wall and two sidewalls, and such walls define an air-admitting passage having d portion in one or more hollow upward extensions of the top wall close to the front end wall.  The extensions have transverse openings which discharge air from the respective portions of the passages into the surrounding atmosphere, namely into fuel which is deposited on the grate. The openings of each extension are located in planes which are inclined to the longitudinal direction of the corresponding top walls through angles of 80-90 degrees, and such openings can be inclined forwardly, rearwardly, downwardly or upwardly.  If the grate bars have top walls with several extensions, the openings in the extensions of each grate bar can be staggered relative to each other.  This also applies for the openings in the extension of neighboring grate bars.  The neighboring grate bars are coupled to each other against sliding movement relative to one another.
