Patent ES-8202219-A1 (ES)
Title: Digital tone ringer.
IPC: H04M19/04
Filed: 1981-01-21
Abstract: A generator of ringing signals at a subscriber station of a telecommunication system, designed to respond to electromechanically generated lower-frequency call signals of large amplitude as well as to electronically generated higher-frequency call signals of small amplitude emanating from a central office, comprises a signal identifier and a level discriminator connected in parallel to an incoming line. The signal identifier includes a local oscillator emitting a train of pulses at a cadence substantially higher than any call-signal frequency which, in the presence of an incoming signal, are fed to a pulse counter during alternate half-cycles of a square wave derived from that signal. The value registered in any of such half-cycle by the counter is digitally transmitted to two circuit branches each comprising a further pulse counter adapted to receive the same square wave if the digital value read out from the first counter indicates a call-signal frequency in a predetermined range which is different for the two branches. Only one branch is enabled at any time, depending on the signal amplitude detected by the level discriminator. The counter in the enabled branch emits an activating pulse, after a certain number of square-wave cycles, to a ringing circuit which converts the locally generated pulse train into an intermittent audio-frequency oscillation driving a ringer the counter of the enabled branch is periodically reset by this circuit which thereby terminates its own operation if that counter does not send out another activating pulse.

Title: Method and device for measuring the parameters of a damped mass/spring system, particularly of the actuating member of a control system.
IPC: G01L5/22
Filed: 1981-05-06
Abstract: A method of measuring the rigidity, the damping coefficient and the inertia of a system consisting of a damped, spring-supported mass, particularly, the manually operable member of the control-system of an aircraft or a flight simulator, in which method the measurement of the rigidity takes place by determining the relationship between the force exerted on the mass and the deviation of the mass from the state of equilibrium at a speed and an acceleration of substantially zero value and storing the relationship. The method is characterized by the initial step of forming three electric signals--namely, a force signal having a value directly proportional to the force exerted on the mass, an acceleration signal having a value directly proportional to the acceleration of the mass, and a velocity signal having a value directly proportional to the speed of the mass. Thereafter, the mass is moved in a manner such that it attains an acceleration and a velocity having values differing from substantially zero and the amplitude of the acceleration signal and of the velocity signal is adjusted such that by subtracting these two signals from the force signal substantially the same relationship to the deflection is obtained as in measuring the rigidity. A device for carrying out the method is also provided.

Patent ES-8303804-A1 (ES)
Title: Method and apparatus for fabricating a tree resistant power cable.
IPC: B29C48/885
Filed: 1982-02-16
Abstract: An improved method and apparatus for fabricating insulated cables, particularly polymeric insulated electrical power cables, resistant to the formation and growth of electrochemical trees is disclosed. Internal pressure on the conductor side of the cable is maintained lower than the external pressure on the outer surface of the insulation during extrusion. Extrusion pressure higher than the external pressure results in expansion of the insulation following extrusion. This expansion or swelling reduces the number and size of cracks and voids which are precursors of electrochemical trees. In addition, pressure curing the extruded insulated cable with a curing medium above its melting point followed by gradual gradient cooling under internal pressure and higher external cooling fluid pressure to around room temperature optimises the resistance of the cable to nucleation and growth of electrochemical trees.
