Title: Automatic kinescope beam current limiter with sequential control modes
IPC: H04N5/59
Filed: 1980-12-12
Abstract: An automatic kinescope beam current limiter for a television receiver comprises a source of signal representative of kinescope beam current conduction, a first transistor responsive to the representative signal over first, second and third ranges of excessive beam currents above a threshold level, and a second transistor. A first control signal derived from the first transistor modifies the video signal peak-to-peak amplitude (contrast level) when beam currents above the threshold level occur. The output of the first transistor is selectively coupled to an input of the second transistor when beam currents beyond the first range occur. A second control signal derived from the second transistor modifies the video signal D.C. component (brightness level) to limit beam currents beyond the first range, whereby both the peak amplitude and D.C. components are modified over the second range. The first control signal is clamped to a fixed level in response to beam currents beyond the second range, whereby the video signal D.C. component is modified alone to limit beam currents over the third range.

Title: Inhalation device with retractible mouthpiece
IPC: A61M11/08
Filed: 1981-04-14
Abstract: An inhalation tube for an aerosol container comprises a tubular body, 1, adapted for detachable fitting to an aerosol container, 6. A delivery mouth-piece, 7, is fitted which is movable between retracted and extracted position. The extraction and retraction of the mouth-piece is brought about by means of a cap, 10, rotatably mounted on the tubular body, which has actuating means, 9, associated therewith. The cap and tubular body have openings of similar dimensions. Rotation of the cap to bring the openings into register causes the actuating means to move the mouth-piece to an extracted position, whilst rotation of the cap to bring the openings out of register causes the actuating means to move the mouth-piece in a retracted, closed-off position wholly with the tubular body. Such an arrangement enables simple functioning of the inhalation tube and ensures that hygienic conditions are provided insofar as the mouth-piece is closed-off when not in use.
Patent ES-8301404-A1 (ES)
Title: Method of and circuit arrangement for supplying current to a two-wire telecommunications line.
IPC: H04M19/00
Filed: 1981-08-24
Abstract: The transverse and longitudinal termination impedances of a subscriber line interface circuit may be independently controlled. The equivalent termination impedance of a subscriber line/trunk appearing to the central office can be adusted upward or downward from a lower resistance value, with longitudnal balance being determined by the matching of feed resistors. The circuit is implementable as a monolithic integrated circuit having low power dissipation, improved power bandwidth requirements, and lower voltage breakdown requirements for integrated circuits all resulting in an improved telephone line interface circuit. Voltage or current feedback to synthesize the proper ac transverse termination impedance from a known dc resistance, is utilized the feed resistors in a telephone line circuit. The transverse and the longitudinal termination impedance are determined by choice of feed resistance value. The independent control of transverse impedance is achieveable as a result of the feedback circuitry being nonresponsive to longitudinal signal.

Title: Automatic twine device for a crop material roll forming machine.
IPC: A01F15/14
Filed: 1982-09-16
Abstract: An automatic twine-wrapping mechanism for a large round baler. The mechanism comprises a twine dispensing mechanism for dispensing twine into the bale-forming chamber of the baler, a reversible hydraulic drive means for cycling a twine arm of the dispensing mechanism back and forth in front of the chamber, a twine wrapping control mechanism for initiating a twine wrapping cycle by sensing the growth of a bale to a predetermined diameter, by automatically actuating a pump drive means for driving a hydraulic pump and by positioning a hydraulic control valve to condition the hydraulic drive means to cycle the twine arm and for terminating a twine wrapping cycle by deactivating the hydraulic drive means following the wrapping of twine around the bale. The twine is automatically severed by a twine cutter responsive to the movement of the twine arm following completion of the wrapping of the twine around the bale. The bale operator actuates a bale ejection mechanism following the cutting of the twine. Following bale ejection, the twine wrapping cycle is terminated by the twine wrapping control mechanism sensing that the bale chamber is empty. The baler is now ready to begin the formation of another bale therein. Also, the twine arm includes a tubular guide and guide support, which in conjunction with a twine tensioner of the twine dispensing mechanism enables simplified threading of twine through the dispensing mechanism.

Patent ES-8607188-A1 (ES)
Title: Process for continuous removal of ammoniacal nitrogen from aqueous streams.
IPC: B01J49/00
Filed: 1985-04-24
Abstract: A continuous process for removal of ammoniacal nitrogen from water is disclosed. This process is useful for maintaining water quality in aquaculture operations, e.g., fish hatcheries and the like. A particulate stream of zeolitic ion exchange material is circulated continuously through an exchanger and a regenerator. An aqueous process stream containing ammoniacal nitrogen, e.g., ammonia, is passed through the exchanger in continuous counter current liquid-solid contact with a stream of particulate, ammoniacal nitrogen-sorbing zeolitic ion exchange material of natural or synthetic origin. A treated liquid water stream having a reduced ammoniacal nitrogen content exits from the exchanger, as does a stream of ammoniacal nitrogen-enriched particulate zeolitic ion exchange material. The latter stream is regenerated in the regenerator at a temperature of about 350 DEG C. to about 650 DEG C. while an oxygen-containing gas stream, e.g., air, is passed in continuous counter current gas-solid contact therewith. Gases emanating from the regenerator are used to preheat the ammoniacal-nitrogen enriched particulate material that enters the regenerator. The regenerated stream of particulate, ammoniacal nitrogen-sorbing zeolitic ion exchange material is recycled to the exchanger.

Title: Cutting edge correction.
IPC: B26D7/26
Filed: 1985-05-08
Abstract: Given the method, the pairs of circular knives (4,5) of a longitudinal cutter apparatus are displaced on rails (7) proceeding transversely relative to the web, being displaced thereon by prescribable positioning distances from an outer, apparatus-fixed bench mark up to a carriage-fixed bench mark. In order to be able to take the alterred position of the cutting edge (19) which may have arisen under given circumstances due to re-grinding into consideration, the distance of the cutting edge (19) from an edge (69) fixed to the carriage of a circular knife is measured by means of position sensors (80) and is input into the control as part of the positioning distances. The carriage (6) is thereby positioned at a different location such that the cutting edge (19) again lies at the proper location despite the re-grinding.
