Patent ES-352375-A1 (ES)
Title: Circuit arrangement for suppressing the intensity of an indicator tube
IPC: G01R13/26
Filed: 1968-04-04
Abstract: In a cathode-ray tube display system in which a plurality of signals are selectively connected to and disconnected from the tube deflection system under the control of individual selector means, operation of the latter to connect or disconnect the signals also results in the production of a beam blanking pulse which blanks the beam before the actual switching operations occur. This removes the trace which the uncontrolled beam movement would otherwise produce during switch-over. The Figure shows an embodiment in which two signals at terminals M1, M2 are selectively connected to a beam deflection winding 2 by the operation of relays 5, 6 controlled by the output of trigger circuits 22, 23 when the potential at inputs a from capacitors 7, 8 falls below a reference potential Uv such operation being initiated by individual selector (switch) means 14, 15, respectively. The operation when selector 14 is utilized to switch the signals of M1 (the operation when selector 15 is utilized being identical) is as follows. On closing selector switch 14, which short circuits U 1 to earth capacitor 7, which is charged to the potential U 1 when 14 is open, commences to discharge to earth via resistor 9 and winding 11 of transformer 13. This produces a pulse in winding 16 which is rectified by one of the diodes 17 or 18 and triggers a mono-stable multivibrator 19 the output of which is applied as a blanking pulse to the beam intensity control electrode 20. When the potential across capacitor has fallen to a value which is less than the reference potential Uv, trigger 22 produces an output which operates relay 5 to switch signals M1 to the deflection winding 2. Mono-stable multivibrator 19 then returns to its stable state and the beam is unblanked. On opening selector switch 14 preparatory to closing selector switch 15 to apply the signals at M2 to the deflection winding 2, a pulse is again produced which blanks the tube beam and when the potential of capacitor 7 reaches the reference potential Uv relay 5 opens to disconnect the source M1.

Patent ES-368047-A1 (ES)
Title: Package and method of packaging perborate-containing products
IPC: B65B55/19
Filed: 1969-06-04
Abstract: A method of packaging a product which generates nascent oxygen, such as one containing perborate, comprises locating the product in a carton formed of cartonboard which contains a source of borate ions, the quantity of the source being at least 160 parts by weight, calculated as boron, per million parts by weight of cartonboard of which at least 80 parts have been applied to the outer surface of the carton. The source of borate ions is preferably boric acid or an alkali metal borate, the preferred materials being boric acid, borase, sodium metaborate or a mixture thereof. Potassium borates, or ammonium borate however may be used. The cartonboard can be treated by applying a boron compound solution to the cartonboard web by a drum coater, size press, or water box on the board machine, or by adding a solution of boric compound to the materials used for coating or sizing the cartonboard. Alternatively, a printing press or coating equipment can be used to apply the boric compound solution. The cartonboard can then be converted into cartons by ordinary methods of manufacture, and the filling can be carried out by wellknown automatic, or semi-automatic, machines. Five examples, with tabulated results of carbon treated with borate ions to prevent "mottling" of the carton, are described.

Patent ES-382647-A1 (ES)
Title: Tank for bulk material
IPC: A01D41/127
Filed: 1970-08-11
Abstract: The grain tank of a combine harvester is fitted with a sensing device to actuate the tipping of the tank by an amount related to the quantity of material in the tank. The tank 14 can pivot in the direction of travel about a hinge 12 and is fitted with a discharge screw 16 situated in a trough 15. A sensing device comprising a plate 18 mounted on a rod 20 is pivotally connected to the wall 22 of the tank, with a rod 32 pivoted to the rod 20 extending into an hydraulic valve 24 such that it is displaceable axially against a spring 26. The rod 32 is arranged to abut the piston 40 of the valve 24 when the plate 18 has moved a definite distance. When the tank 14 is full, the plate 18 is subjected to a pressure, under which the rod 32 and spring 26 adjust the valve 24 to a neutral position. To empty the tank, the drive of the discharge screw 16 is switched on and the main valve 46 is set to "lift", so that the pressure fluid flows from the pump 58 via 54 to the valve 24 and via 50 back to the fluid tank 52. When the tank 14 has been emptied to such an extent that the load is removed from the plate 18, the rod 32 moves away from the piston 40 and the valve 24 is actuated so that pressure fluid passes from the pump 58 along lines 60, 54 and 43 into a lifting cylinder 44 on each side of the tank. The tank is thus tipped about 12 until the plate 18 is again acted upon and the valve 24 is reset in its neutral position. The process is continued until the tank is emptied, when the main valve 56 is set to "lower" and the tank resumes its horizontal position. The sensitivity of the sensing device is adjustable in accordance with the specific gravity of the lightest material to be put in the tank. In a second embodiment, Fig. 5, the tank is in two parts, one part 70 secured to the harvester and the other 72 tippable about a hinge 12a. The operating procedure is as before. Strips of rubber 82 are fixed to the walls 78, 79 of the tippable part 72 to form a seal between the two parts of the tank. In other embodiments, the valve 24 can be operated electromagnetically by a relay, or by photo-cells or like devices measuring the volume of material in the tank.

Title: Video signal processing system and method with above-white-level noise inversion
IPC: H04N5/213
Filed: 1973-07-23
Abstract: This disclosure depicts method and apparatus for processing a television video signal, particularly for processing a noise-adulterated video signal as developed by synchronous-type video detectors. The disclosed method and apparatus involves sensing in a video signal developed by a synchronous-type video detector noise components having amplitude levels exceeding a predetermined reference level above a level which corresponds to a maximum white video display. A modified video signal is developed for supply to the luminance controls of a video image display device. In the modified signal the sensed above-white-level noise energy is inverted so as to prevent over-driving of the associated image display device. The noise-adulterated video signal from the video detector is supplied directly to a sync separator and AGC stage without noise inversion so as to avoid the introduction of a spurious DC component capable of falsely altering the video signal level relative to an AGC reference level.
