Patent ES-358605-A1 (ES)
Title: Signal translating system which rejects a particular frequency
IPC: H04N9/64
Filed: 1968-09-27
Abstract: In a television receiver signals are processed by a tuner 12 and amplifiers 14, 16 to provide video and audio components at intermediate frequencies. An intercarrier channel 20 feeds a loud-speaker 22, and the video componants are detected in a circuit 26 after separation by a band-pass filter comprising two inductively coupled resonant circuits 56, 64 made up, respectively, of inductors 46, 48, 50 and associated capacitors 52, 54, and of an inductor 60 and an associated capacitor 62. A trap circuit 38 tuned to the intercarrier frequency follows the video detector circuit and a circuit 68, which is resonant at or near the intermediate frequency of the sound carrier provides a voltage to the resonant circuit 64 which is adjusted to be substantially equal and opposite to the intermediate sound carrier component induced therein by the coupled resonant circuit 56. The resonant circuit 68 comprises an inductor 70 and a capacitor 72. A tap on the inductor 70 is connected to the resonant circuit 64 and the circuit is completed through a capacitor 74 to earth. The resonant circuit 68 is fed from the inductor 46 of the resonant circuit 56 by means of coupling coils 76, 78, in series with a capacitor 82 and an inductor 80, a damping resistor 84 being shunted across the said capacitor and inductor.

Patent ES-463724-A1 (ES)
Title: Control for wire coating line
IPC: B29C48/92
Filed: 1977-10-31
Abstract: A control is provided for a wire coating line which includes means for driving wire along a path at controllable speed while coating it with plastic extruded at a controlled rate and temperature, and cooling means are located at a controllable distance from the coating means to solidify the plastic. The controllable factors affect both the capacitance and diameter of the wire produced. The control allows the line to be run in accord with stored digital values for the matters to be controlled. Closed loop control is provided because the relevant factors of line operation are measured, the analogue measurements converted to digital values and compared with the stored values to produce a control signal which has the effect of reducing the differences between a desired and measured line condition as represented by the digital values compared. Closed loop control is also provided for control of the line to produce desired capacitance or diameter values in the coated wire. Whichever of capacitance or diameter is used as the basis for line control is measured and provided as a digital value to the control. This digital value is compared to a stored digital value representative of the desired capacitance or diameter. The results of the comparison is used to update the stored digital value for an operating condition of the line so that the parameter is altered to provide an operating condition which brings the capacitance or diameter closer to the desired value.
Patent ES-476362-A1 (ES)
Title: Improved pressure release closure.
Inventor: DEBENHAM M
IPC: B21D51/44
Filed: 1978-12-27
Abstract: A push-in pressure releasing resealable closure for an aperture in a sheet metal container member is disclosed, wherein the closure is integral through a connection of metal to the remainder of the container member. The closure is designed so that it is depressible into the container by flexing about the connection when push-in force is applied to the closure, without exceeding the elastic limit of the connection, so that the closure is returned at least substantially to its original position to seal the can contents, upon removal of the push-in force from the closure. The closure is particularly suitable for use in containers for carbonated beverages, such as carbonated soft drinks and beer, so that the gas pressure within the container may be released without danger of substantial gushing or spurting, to permit a larger pouring opening in the container member to be opened. The specification discloses several embodiments of the pressure releasing closure including one in which the closure is formed partly within a pouring closure and partly outside said pouring closure whereby the pressure releasing closure is permanently opened by the opening of said pouring closure to create an air vent or liquid draining opening outside the pouring closure. The specification also discloses methods of forming closures in which the number of forming stages is reduced. In one method, the closure piercing operating is performed at the same time as the edge of the tab is downwardly reformed. In another method, the sheet metal around the opening is also reformed in the same operation.

Patent ES-483762-A1 (ES)
Title: Improvements in belt casters.
IPC: B22D11/06
Filed: 1979-08-31
Abstract: In the continuous casting of metal in strip form between moving belts while maintaining a flowing layer of liquid coolant between the reverse surface of a belt and mutually adjacent, guiding-surface, nozzle elements that deliver such coolant, such elements are each constituted as a cooling and guiding unit having a hexagonal face and including releasable retaining elements normally holding such face (through which coolant is projected against the belt) at desired level under spring pressure against the engaged elements. The elements, respectively with the hexagonal head and with a fixed support, are disengaged by depressing the head and turning it, thus allowing removal of the device for replacement or service. As the hexagonal heads can be arranged very closely together, except for narrow, liquid-withdrawal spaces between adjacent edges, practically complete support for a coolant layer across and along the entirety of the belt, is attainable, yet with practicality of construction of the units. The engageable elements can be so arranged and shaped as to permit slight tilting of the hexagonal head units, for even greater conformity with the requirements of belt cooling.
