Title: Improvements in or relating to signalling conductors
IPC: H01B11/14
Filed: 1931-10-09
Abstract: 390,822. Cables. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Gilbert, J. J. ; 16, Pine Street, Douglaston, New York, U.S.A.) Oct. 9, 1931, No. 28137. Convention date, Oct. 30, 1930. Addition to 339,968, [Class 36, Electricity, Conducting &c.] [Classes 36 and 37.] In a cable composed of core lengths twisted together and so chosen that the electrical properties of the lengths in a pair are nearly equal, as described in the parent Specification, the lengths are matched for the longitudinal inductance component described in Specification 206,104, [Class 36, Electricity, Conducting &c.], as well as for other properties. To enable this to be done the core length 10 is wound from a reel 20 to a reel 21, passing on its way through a coil 30. The reels 20, 21 are mounted on insulated stands 22 and connected to the ends of the core length, so that a current can be passed through it by means of a battery 24, and interrupted as required by a key 25. The currents induced in the coil 30 in consequence of the longitudinal component in the induction can be read on a ballistic galvanometer 35, or by means of a flux-meter 20 which can be connected to the coil 30 through an amplifier 37. The longitudinal component of the inductance can then be plotted along the length of the core and two portions showing similar curves combined. Instead of measuring the component for a single core two cores may be twisted together and their combined component measured ; two pairs giving similar results are then combined to form a quad.

Abstract: 388,477. Telephone and like transmission measurements. LIGNES T•L•- GRAPHIQUES ET T•L•PHONIQUES, 26, Rue de la Pepiniere, Paris. Oct. 20, 1931, No. 29139. Convention date, Nov. 14, 1930. [Class 37.] For the measurement of transmission levels on telecommunication circuits, the voltage at the point to be measured, or the voltage at this point and an adjacent point, is applied simultaneously along two conducting paths to an indicating device, the phase and modulation of the voltage (reference voltage) in one path being adjusted to neutralize the effect on the indicating device of the voltage under measurement. An indicator 9, Fig. 1, is connected to the transmission line 1, 1<1> at the point 2 at which the voltage level is to be determined. The reference voltage is taken from the line at a neighbouring point 3. The points 2, 3 may be merged together. The voltage at the point 3 is amplified by a voltage amplifier 4 having a high input impedance and a fixed gain. The amplified voltage is fed through a phase-changing device 5 to a power amplifier 6 having a variable gain. A measuring instrument 7 calibrated in voltage levels and a fixed resistance 8 are connected in series across the output of the amplifier 6. By means of this amplifier the modulation of the voltage across the resistance 8 may be varied. The phase-changing device, 5 allows the phase of the voltage across the resistance 8 to be varied without changing its amplitude. One form of phase-changer is shown in Fig. 2, in which fixed condensers C<1> of equal capacity and variable resistances R are connected as shown between terminals A .. D. The voltage across the resistance 8 is applied to the indicating apparatus 9, which may be a high-impedance telephone receiver, in opposition to the voltage at the point 2 and the modulation and phase of the reference voltage are adjusted until a null indication is obtained. The voltage level is then read directly on the instrument 7. The amplifier 6 may have a fixed gain, a voltage reducer being employed.
