Patent ES-367454-A1 (ES)
Title: Color television receiver
IPC: H04N9/71
Filed: 1969-04-20
Abstract: In a colour television receiver in which the control electrodes of the cathode ray tube are coupled to the respective chrominance channels by capacitors 72 and are returned to a reference D.C. potential during the horizontal retrace time by synchronous clamps activated by pulses from a vision blanking circuit, the chrominance channels are usually gated off at each horizontal sync pulse so as not to pass the colour burst, but such gating action produces a pulse which may disturb the relative and absolute quiescent output levels of the chrominance channels and cause the control electrodes to be clamped at an erroneous D.C. level, giving a wrong overall colour balance. In the present invention, further pulses from the blanking circuit are applied to a non-gated portion of the chrominance channels and are of an amplitude and polarity such as to cancel the pulse produced by the gating. By varying the amplitudes of the further pulses the colour balance of the picture may be selectively controlled and the tint of a monochrome picture may, or may not be, simultaneously controlled. In Fig. 2, the output of a chrominance amplifier 22, with the colour burst removed, is fed to one (of two) balanced diode demodulators, producing B-Y information at the grid of a valve 65 which feeds the B-Y grid via capacitor 72. During horizontal retrace, A negative pulse from blanking circuit 15 clamps the B-Y grid, via diode 74, to a reference D.Z. potential determined by the size of the pulse and the setting of potentiometer 77. When amplifier 22 is gated off, a spurious pulse appears at the grid of valve 65 which is compensated by application to the valve cathode of a pulse from the blanking circuit of suitable polarity and of an amplitude determined by the setting of potentiometer 81. A similar technique is used in the R-Y channel, but is of course unnecessary in the G-Y channel where the signal is produced by matrixing the outputs from the R-Y and B-Y valves 15. During monochrome transmissions, the valves 65 are held inoperative by a colour biller circuit 41 so that the spurious and compensating pulses do not appear at capacitor 72 and a correctly set black and white picture is produced. If the colour biller circuit is applied at 65 are operative during monochrome transmissions, both types of pulse appear at capacitor 72, and the colour balance will be the same as during colour transmission i.e. giving tinted pictures if desired.

Patent ES-410013-A1 (ES)
Title: Nestable fabricated thermoplastic container and method of fabrication same
IPC: B65D8/00
Filed: 1972-12-23
Abstract: A fabricated cup or other nestable container in which the sidewall is formed from a rectangular sheet-like blank of a thermoplastic material, particularly an expanded thermoplastic material, the blank having its ends joined to one another in a liquid-tight seam extending the full height thereof to form a sleeve, the blank having a relatively high degree of orientation or heat-shrinkability extending circumferentially of the sleeve, the fabrication of the sidewall from the sleeve being accomplished by telescoping the sleeve over a generally frusto-conically shaped mandrel, by exposing the sleeve to heat to cause it shrink to conform to the configuration of the mandrel and by stripping the shrunken sleeve from the mandrel. A two-piece container may be formed from such a sidewall by affixing an end closure element to the bottom or smaller end of the sidewall. A one-piece container may also be formed in this manner by using a blank of sufficient height so that a substantial portion of the sleeve formed therefrom extends beyond the smaller end of the forming mandrel, such substantial portion, when the sleeve is exposed to heat, being shrinkable to form an annular planar portion disposed transversely of the longitudinal axis of the mandrel and a relatively small tubulation which extends longitudinally from the interior of the annular planar portion and which, by the application of pressure thereto while at elevated temperature, may be caused to collapse and fuse together to close the bottom of the container in a liquid-tight manner. A container of this type may be used to advantage to contain any liquid or other fluent product therein in face to face contact with the interior surface of the sidewall thereof, and when the container is fabricated from an expanded material, because of the insulating characteristics of such material, a container fabricated therefrom may be used to particular advantage as a handholdable cup for coffee or other hot beverage.
