Patent ES-478053-A1 (ES)
Title: Display tube for displaying color pictures
IPC: H01J29/51
Filed: 1979-02-24
Abstract: Because the deflection fields in color television display tubes on the display screen side often have a pin-cushion-shaped and barrel-shaped field distribution, a defocusing of the electron beams occurs upon deflection. By forming the barrel-shaped deflection field on the display screen side of the display tube so as to be pin-cushion-shaped on the neck side near each electron beam and simultaneously deforming the deflection field which is pin-cushion-shaped on the display screen side of the display tube so as to be barrel-shaped on the neck side near each electron beam, the effects of said defocusing of the electron beams as a result of the deflection are considerably reduced. The haze occurring in the vertical direction is also reduced.
Patent ES-479609-A1 (ES)
Title: Device for attaching two metal sheets or blanks together
IPC: F16B5/06
Filed: 1979-04-16
Abstract: Device for attaching two metal sheets or blanks together for absorbing the forces occurring particularly in ventilating systems to prevent loosening without requiring supplemental sealing means. The sheets or blanks to be fastened to one another are specially shaped and configured and are formed from blanks configured appropriately for the desired purpose. The clamped sheets are deformable in a corrugated-like manner in the region of clamping and within described parameters make it possible to secure previously unobtained extraction forces. The degree of bend and the angle and spacing between the legs determine the transmission of force.

Title: Electrical alarm circuits and systems.
IPC: G08B25/01
Filed: 1979-04-17
Abstract: Intrusion-detection units (1) which are linked in an alarm system to a central control unit (3) by cable (2), each include a coder circuit (8) responsive to opening of intrusion- and tamper-alarm contacts (5, 6) to change the magnitudes of current flow in respective alarm and tamper signalling lines (14, 15) of the cable (2). Current is supplied to the tamper-signalling line (15) in the circuit (8) via the collector-emitter path of a transistor (16) from the positive supply-line (10) of the cable (2), until the alarm-contacts (5) in its collector circuit open, whereupon current supply of the same magnitude is continued to that line (15) via the base-emitter path from the alarm-signalling line (14). The increase in current in the latter line (14) is detected, to indicate the alarm condition, in a decoder circuit (9) of the control unit (3) by operational amplifiers (36, 40) that respond to the consequent tendency for change in potential of the line (14). The decoder circuit (9) also includes operational amplifiers (22, 23) to detect change in current magnitude in the tamper-signalling line (15) for indicating the tamper condition, such change occurring upon opening of the tamper-contacts (6) of any coder circuit (8) or any breaking or shorting together of the lines (10, 11, 14, 15) of the cable (2). Opening of the tamper-contacts (6) interrupts a current-supply path that is connected to the tamper-signalling line (15) in parallel with the collector-emitter path of the coder-circuit transistor (16), or alternatively interrupts the emitter circuit of that transistor (16). A resistor (20) is connected across the supply-lines (10, 11) to increase current supply to the tamper-line (5) via a diode (21) if the negative supply-line (11) is broken.

Title: Method for producing anhydrous alumina
IPC: C01F7/444
Filed: 1979-07-18
Abstract: This invention relates to a method for the production of anhydrous alumina having a desired alpha -conversion from alumina trihydrate. This method is directed to production of anhydrous alumina having a desired alpha -conversion from alumina trihydrate in which water is removed in a precalcining zone wherein the alumina trihydrate is heated to a temperature below 450 DEG C. Then, the precalcined dehydrated alumina is recrystallized to alpha -alumina in a reaction chamber by directing an oxygen containing gas to the reaction chamber, mixing and suspending the precalcined alumina and fuel in the oxygen containing gas and feeding the mixture to a combustion zone, followed by exothermal recrystallization of the alumina which is initiated by rapidly heating the precalcined alumina by burning the fuel in the oxygen containing gas in the hot combustion zone and withdrawing the recrystallized alumina from the top of the reaction chamber suspended in a combustion gas stream. The recrystallized alumina is then separated from the gas stream and cooled to produce anhydrous alumina having the desired content of alpha -conversion.
