Patent ES-359131-A1 (ES)
Title: Improvements in or relating to data processing systems
IPC: H04Q3/545
Filed: 1968-10-14
Abstract: In a data processing system messages to be transmitted are compiled as an arbitrary number of equal-sized words and the number of such words constituting a message is sent prior to sending the message. The specific embodiment relates to a processor controlled telephone exchange and the signalling employed between the processor and a buffer circuit serving a mixed group of individual circuits comprising a switching network. The messages between the processor and a buffer circuit comprise a number of sections each of the same bit length. The first section indicates the total number of sections constituting the message, the second and possibly also the third sections indicate the address of the network equipment to which the message relates, while the succeeding sections to a maximum of a further four comprise control data relative to processor work functions. In transmitting from a buffer to the processor reception of the message length indication is acknowledged by the processor to elicit the next section of the message and so on. Message length is recorded in both buffer and processor to determine the last section sent and received. In transmitting from the processor to a buffer, the processor sends the acknowledgment signal to prepare the buffer before sending each section of a message. Absence of acknowledgment signal or reception of data in illogical order results in fault signals. The exchange system is the same as that described in Specification 1,205,305.

Title: Addition circuit for the digital codes generated in accordance with a nonlinear compression law
IPC: H04B14/04
Filed: 1968-10-16
Abstract: In a pulse code modulation system providing conference facilities a companding circuit comprises coding and linearizing systems operating according to an approached logarithmic law. The graph, Fig. 1, relating amplitude X as a proportion of permissible maximum to binarycoded compressed signal Y, is made up of a number of straight lines with gradients successively related as 2: 1 on either side of the origin. The highest digit of Y is 1 or 0 according to whether Y is +ve or -ve. In the latter case the code is in complementary form. The amplitudes of the speech pulses of the parties in conference are expressed in linear form in binary-decimal code in register 3, line I, Fig. 3, where the most significant 1 represents the fractional point. At the same time register 4 receives binary 7. Compression then takes place by stepping register 3 leftwards and register 4 down until the position F is reached with the code and mantissa in registers 4 and 3, respectively, the initial 1 in register 3 still representing the fractional point. The value is now expressed in binary-decimal code approximating the logarithm to base 2. Linearization is effected by the reverse process (Fig. 4, not shown). Addition of amplitudes. Fig. 5.-A central control CC receives 7-digit codes a, b of speech values obtained from two parties in a threesided conference. CC then applies a, b to a logical circuit Le in true or complementary form according to whether the highest digit is 1 or 0. Lc and Li from comparison of a and b decide whether the values are to be added or subtracted and whether the result is to be +ve or -ve. The values a, b are then linearized in translator T under control of sequencer S, the resultants being added (or subtracted by complementary addition) in AD and passed back to T for compression. The resultant code is directed to Ls and back to central control CC, which directs the answer to the third party in the conference.

Filed: 1968-12-07
Abstract: A tuning arrangement in a superheterodyne receiver operating on two frequency ranges, comprises one or more resonant circuits 22, 24 tunable to signal frequencies and an oscillator circuit incorporated in a local oscillator 1, and also includes variable capacity diodes 29, 32, 33, 4 for tuning the circuits and switching diodes 35, 38, 39, 12 for changing range, being conductive in one switching condition and cut off in the other switching condition. It is characterized in that a switching voltage supplied by a D.C. voltage source-as shown, stabilized by means of Zener diode 41-is applied via switch 42 to keep the switching diodes conductive in the first-mentioned switching condition, while in the other condition the blocking voltage is generated by rectification of the local oscillations, the switching diode 12 of the oscillator circuit acting as the rectifier. In this condition a resistor 43 is shunted across Zener diode 41 to form a bypass for the current which in the first condition is carried by resistors 34, 36, 37, 45. To enable the oscillator to start, in the second switching condition, when it is initially loaded by diode 12 with a low impedance, a capacitor 19 is shunted from base to emitter of transistor 1 this is arranged to resonate with the natural input inductance of the transistor at a frequency intermediate the two operating ranges, oscillation commencing on this frequency and changing to that of tuned circuit 2, 3, 4 when the diode 12 biases itself back and so removes the damping from this circuit.
