Patent ES-366493-A1 (ES)
Title: Integrated monolithic semiconductor voltage regulator arrangement
IPC: H01J31/48
Filed: 1969-04-26
Abstract: The drive transistor(s) associated with one or more power transistors are of complementary type thereto all the transistors are integrated in a single semi-conductor body which has a low resistivity substrate heavily doped with an impurity of low diffusion coefficient and bearing an epitaxially grown layer of lower doping and higher resistivity. Zener and rectifier diodes, resistors and a junction capacitor may be integrated in the same body. Two structural types are outlined in one the substrate and layer are of the same conductivity type, in the other they are of opposite conductivity types. In the case where the substrate and layer are of the same conductivity type the power transistors are double diffused and complementary transistors are triple diffused. The power transistors share the common substrate as collector region, this being provided with a bottom surface electrode. Isolation between the power transistors and the complementary transistors utilizes the epitaxial layer it is stated that further diffusion into the layer may enhance the isolation. In the case in which the substrate and layer are of opposite conductivity types the substrate again forms the common collector of the power transistors but these are formed by a single diffusion (to form the emitter region) and have a homogeneously doped base, the epitaxial layer. The complementary transistors are formed by double diffusion and are isolated by normal junction isolation diffusion extending through the epitaxial layer. The circuits described are on-off series switching regulators for feeding the field winding of a generator the voltage of which is being regulated. In each regulator the power transistor(s) is (are) in series with the field winding of the generator. The input to the regulator is parallelled by a Zener diode to protect the regulator (and entire system) against gross over voltages. The line voltage is sensed by a potentiometer and Zener diode combination and used to switch one or more driver transistors when the diode changes state. This Zener diode may be formed by the addition of a second "emitter" region to the (or the first) driver transistor. One or more normal diodes may be connected in series opposition with the Zener diode to provide temperature compensation. Further temperature compensation may be provided by suitably placed resistors in the circuit. The circuits incorporate positive feedback to ensure complete switching of the power stage, thus the field winding is either fully energized or is not energized-the winding is shunted by a free running diode to give safety in this mode of operation.
Patent ES-370122-A1 (ES)
Title: Bi-directional translator circuit
IPC: H04Q3/00
Filed: 1969-07-31
Abstract: A bi-directional relay translator is provided which responds to a local call for translating the equipment number of a calling line to the directory number of that line and which responds to a terminating call for translating the directory number of the called line to the equipment number of that line. The translation of an outgoing call is initiated by operation of the calling line relay which provides an equipment number identification, following which a translation to decimal directory number is effected. In the reverse direction, when a directory number is registered, completion of the registration initiates a translation of the decimal directory number to an equipment number.

Title: Control device having means for electrically simulating and compensating the inertia momentum of the moving parts of an electrical positioning means
IPC: H02P3/24
Filed: 1970-02-06
Abstract: A servo system comprises a reversible induction motor which adjusts valve 5 through gear or hydraulic transmission, the valve spindle being coupled to a position transducer 7 supplying a signal to logic circuit 10. A comparator 44 receives the signal i as well as a reference signal s and forms a deviation signal a which is amplified to provide signal b. A transmitter 46 receives the signal and a preset signal e which adjusts the limit G1 required for the appearance of an output signal c for switching on the motor. A further correcting signal d depends upon the length of time the motor has been switched on to allow for the inertia of the moving parts. It is triggered by the signal c which is inverted and integrated. The sum of the signals b and d decreases in accordance with the duration of the signal c until the motor is switched off at the limiting value G2. The switching off time of the motor is displaced as the length of time the motor has been switched on increases. The signal c is applied through AND gate 49 to store 53 associated with AND gates 54, 55 for controlling SCR switches 57. 58 through trigger circuits 56, 59. The sign of the signal a determines which of the switches 57, 58 will be triggered. A D.C. source 25 is provided for braking the motor, the said source being connected to the stator winding when the A.C. supply is removed The D.C. voltage is reduced when the motor comes to a stop. A current measuring network 15 provides a signal for switching off the motor when a current limit is exceeded. The current limit is increased for a predetermined period when the motor is being started, this period being prolonged if the valve is near its closed position. If an over current is indicated when the valve is not near its closed position, an alarm is given. A limit 30 compares the instantaneous voltage in the supply lines S and T and provides a signal m for switching the motor on or off only if the instantaneous voltages are equal and positive.

Title: Phosphates
IPC: D01F11/14
Filed: 1970-11-27
Abstract: Complex phosphates of aluminum containing a halogen and chemically-bound molecule of a hydroxy compound, which may be water or an organic hydroxy compound. A typical example is a complex phosphate containing ethyl alcohol having the empirical formula AlPClH25C8O8. They are most conveniently prepared by the reaction of an aluminum halide with the appropriate hydroxy compound and orthophosphoric acid, under relatively cool conditions. The compounds are generally soluble in water and polar organic solvents. They decompose at low temperatures to give aluminum orthophosphate, thereby providing a method for producing aluminum phosphate in many forms, for example, fibers, coatings, binders and fine particles, from a solution in water or organic solvents.

Title: Control circuit for PCM TDM async. integrated telephone exchanges - uses one exchange to synchronise other to reduce number of speech buffers
IPC: H04J3/18
Filed: 1971-10-02
Abstract: The control circuit, for PCM TDM a sync. integrated telephone exchanges, reduces the number of buffers or speech memories in the input circuitry by operating both transmission directions in synchronism with one exchange (Vstl). One of the input circuits of the neighbouring exchange is used as a synchronising group (SG) for all read and write operations in time with its own exchange. The other input circuits are operated as a sychronous groups (AG), without buffers, for the read and write operations of their own exchanges. These other circuits are synchronised with the circuits of the first exchange. Transit time equalisation between transmission directions takes place only in the synchronous group.
