Patent ES-8606757-A1 (ES)
Title: Circuit arrangement for frame and phase synchronisation of a sampling clock at the receiving end.
IPC: H04L7/04
Filed: 1984-09-17
Abstract: With such a circuit arrangement, the sampling clock is synchronized to the frame position and the phase of the characters of a received character stream containing a "unique word" at regular intervals. In a digital correlator (1), a crosscorrelation function is generated from a unique word stored therein and from the received, sampled character stream, and a frane detection circuit (2) derives a frame clock (RT1) from those maxima of the crosscorrelation function recurring at intervals of one frame period. To achieve synchronization at any polarity of the received character stream (i.e., even if the tip and ring wires of the subscriber line are interchanged), a second frame detection circuit (3) derives a second frame clock (RT2) from those minima of the crosscorrelation function recurring at intervals of one frame period. A clock selection circuit (8) determines which of the two frame clocks is received within a limited time interval. From this frame clock, control information for representing the phase of the sampling clock (AT) is derived in a phase synchronization circuit (10).

Patent ES-8702753-A1 (ES)
Title: Transformerless drive circuit for operating a field-effect transistor switch.
IPC: H03K17/06
Filed: 1985-05-24
Abstract: A transformerless drive circuit for operation of a switch mode regulator includes a turn-on circuit and a turn-off circuit coupled to a control terminal of the switch, respectively, for inducing a state of conduction in the switch and for terminating the state of conduction. The switch is, in the preferred embodiment, a P-channel DMOS field-effect transistor (FET) with a source electrode connected to the positive voltage terminal of a power supply, and with the drain terminal connected to load circuitry of the regulator. The gate electrode serves as the control terminal. The regulator includes a sensor of output voltage and circuitry for providing a pulse-width modulated control signal for designating the average amount of current to be passed by the switch. The turn-on circuit and the turn-off circuit share a common diode which operates alternately for conduction or turn-off. The turn-off circuit includes a bootstrap capacitor for momentarily powering the circuit for saturating a transistor therein, the relatively low saturation voltage being impressed at the control terminal for rapid turn-off. The drawing of current by the turn-on circuit pulls a gate-voltage away from the power line for rapid turn-on.

Filed: 1986-01-20
Abstract: In a simple and inexpensive method of manufacturing an elongate core for use in an optical cable, a flexible reinforcing member 1 is caused to travel through an extrusion machine 2 and a circumferential wall of plastics material is extruded around the member. Downstream of the extrusion machine 2, a plurality of circumferentially spaced, longitudinally extending grooves, e.g. helically extending grooves, are formed in the soft outer surface of the plastics wall by deforming the plastics material in such a way that there is no wastage of plastics material. Deformation of the plastics wall is preferably effected by freely rotatable discs 4 whose axes of rotation extend transversely of the axis of the advancing plastics covered reinforcing member 1 and which are urged into and effect longitudinally continuous indentations or grooves in the plastics material of the wall. Preferably, optical fibres are fed into the grooves of the plastics covered reinforcing member 1 after the grooves have been formed.

Patent ES-8703358-A1 (ES)
Title: Improved vehicular hill holder system.
IPC: B60T13/66
Filed: 1986-04-30
Abstract: A brake booster (10, 210) connected to a control circuit (120) provides a system for the continued braking of a vehicle when the vehicle is situated on an incline and the brake pedal (92) is released by the operator. Continued brake application is accomplished by utilizing a control circuit (120) responsive to vehicular attitude, clutch pedal position, and vehicular direction. The control circuit (120) is connected to the combination of a check valve and two-way solenoid valve (100, 200) connected to a movable wall brake booster (10, 210). The combination valve (100) is connected to a flexible hose (110) disposed interiorily of the booster (10), and the other end of the flexible hose (110) connected to the input opening (32) of a three-way poppet valve (70) located at the central hub (30) of the booster (10). When the control circuit (120) senses that the vehicle is on an incline, the clutch pedal depressed, the ignition "on", and the vehicle not backing up, it actuates the two-way solenoid of valve (100) which continues to supply a first fluid pressure to the front booster chamber (40) while closing to prevent the supply of the first fluid pressure to the rear booster chamber (50) via the flexible hose (110) and poppet valve (70). The vehicle operator may release the brake pedal (92) which returns slightly toward an inactive position and which opens slightly valve (70), with the brakes remaining activated because the second fluid pressure is maintained in the rear chamber (50) by the closed valve (100) so that the second fluid pressure may not escape via hose and connection (110) and valve (70), and thereby maintaining the axially displaced position of the movable wall (24).
