    Abstract: In this integrated and miniaturized crosspoint packed in a sealed casing which forms a magnetic shielding, each reed is surrounded by a coil, and is tailed in a base while its end carries the contact. Two such reeds are respectively inserted in two coils or coil assemblies located side by side, to form a contact arrangement. Each reed is made of two half-reeds forming a closed V, one branch of the V being made of resilient material and having its top end secured to the base, while the other branch is made of magnetic remanent material and carries the contact material located at its top end.

    Abstract: This relates to level regulation in a carrier frequency system with a plurality of repeaters in tandem. More particularly, the level regulator at the repeaters suppress overshoot (excessive regulation) by one or more regulators. The level regulator is disposed in each repeater of a pilot-controlled repeater chain. Suppression of overshoot is obtained by a gradient discriminator in each repeater which detects the rate of change of the pilot level deviation from a nominal level. If the rate of change exceeds a predetermined value, the level regulator is blocked.

    Abstract: This relates to a PCM system having a substantially constant power amplitude distributed throughout the frequency spectrum of a digital signal. This enables selecting a suitable portion of the spectrum of the digital signal for operation of the AGC circuits of the system, particularly those AGC circuits contained in predetermined ones of repeater incorporated in the system. To accomplish this, the system includes, in the transmitter, a pseudo-random scrambler operating on a binary signal input to provide the substantially constant power amplitude distributed throughout the frequency spectrum of the input binary signal. The output signal of the scrambler is converted to a ternary signal prior to transmission. At the receiver the ternary input signal is converted to a binary signal. The binary signal at the output of the last converter is descrambled to compensate for the scrambling of the scrambler and to produce a replica of the binary input to the system.

    Abstract: A distributor is disclosed for a centrally controlled telephone exchange enabling the control of bistables distributed in groups. The distributor receives from the central unit for a group of bistables to be controlled a control data item indicating the bistables to be set in position 1 and 0, and an inhibition data item indicating the bistables whose position must remain unchanged and serving to mask the elements of the control data corresponding to these bistables. The central unit function is thus limited to the elaboration and to the transmission only of the control data elements intended to certain components of an addressed group.

    Abstract: This invention provides an improved magnetic core matrix code translator wherein each core in the decoder section thereof covers two digital possibilities rather than a ''''unique'''' digit representation. Moreover, each of the code wires running through the decoder cores is divided at the output thereof into anywhere from 2 to 32 branch lines which are then run through the cores of a coder stage to form 1-out-of-32 possibilities. These lines each terminate in a transistor switch operated by a control circuit. Since each decoder core represents two possibilities, selection of but one transistor switch is required, and is effected by the control in response to a gated output determined by the ''''control'''' bits of each code element.

    Abstract: There is disclosed herein a signalling process for a PCM transmission system having reduced disparity, that is, a substantially equal number of binary ''''1'''' digits for the pulse stream. This is accomplished by complementing normal PCM words if the number of binary ''''1''''s in a word are less than n/2, where n is equal to the number of digits per word, and using alternatepolarity bipolar code PCM transmission. In accordance with the present invention the complementing of PCM words is indicated by a polarity violation of the bipolar code of the first digit of the complemented words. This results in two pulses of the same polarity being adjacent each other rather than alternate polarity as is usual in alternate-polarity bipolar PCM. Transmission and reception circuits are also disclosed to implement the PCM signalling process of this invention.

    Abstract: An input system for an electrical machine including a mechanism for connection between each key and a shutter therefor in the keyboard of the console of the machine. The shutter interrupts light from one or more sources to one or more photocells to provide a coded input for the machine. The shutter of each key is moved by the mechanism by a snap action to avoid the need for interlocked keys. Simultaneous inputs from two keys are avoided because the shutter is moved by the mechanism at a substantially greater rate than it is possible to actuate a key manually.

    Abstract: In this multiple, magnetically-operable bistable reed arrangement, the reed tube contains two electrically separated, polarized contact sets each of which consists of two contact arms and an armature permanently connected to and magnetically separated from one of the contact arms. The respective associated contact arms are brought out as contact terminals at the same end of the reed tube and form, inside the reed tube, a magnetic operating air gap along with the free end of the armature, which projects into the space between the contact arms. Each of the armatures is suspended from one of the two associated contact arms by a non-magnetic spring, with the armatures being so arranged as to overlap each other considerably in order to mutually assist each other in their magnetic coupling when the operating coil is excited.
