Title: An improved indicating device applicable for apparatus employed for measuring quantities depending on two variable factors
IPC: G01P5/00
Filed: 1920-05-13
Abstract: 162,547. Gros, P. M. F. Dugit-, (known as Dugit, M.). May 13, 1920. Multiple-indication apparatus; index hands and pointers; modifying scale of readings.-In apparatus for indicating values dependent upon two variables, two pointers, one or both of which is curved, are mounted coaxially and moved in accordance with these variables so as to give, by their intersection against a series of stationary curves, the values required. The pointers may be replaced by lines or a series of lines on transparent discs. In an instrument for measuring the air-speed of aircraft, a curved pointer 27, Figs. 1 and 2, actuated according to the pressure in a Venturi tube 15 by means of connections including an aneroid chamber 17, an oscillating plate 21, and toothed sector 24, co-operates with a straight pointer 13 controlled by the static air pressure through similar pressure and transmitting devices 1, 6, 9, and the intersection of the pointers is read to give the air-speed, against a series of curves V<0>, V<1>, V<2>. The pointer 27 may take the form of a curved rod 37, Fig. 4, a circular rod, Fig. 5, or a segmental plate. In the form shown in Fig. 8 a third factor is introduced; one of two transparent discs 14, 27<1> rotated according to the two variables bears curves T<0>, T<1> T<2>, representing densities corresponding with different temperatures, and the intersection of the curve concerned with a fixed pointer 13<2> enables the speed to be read as shown by the curves V<0>, V<1>, V<2>. The invention may be applied to electrical power measuring instruments and to devices for checking or controlling a dual manual drive which has to maintain a given resultant.

Title: Improved apparatus for the measurement of electrical quantities at high frequencies
IPC: G01R23/00
Filed: 1941-10-16
Abstract: 551,588. Current voltage and impedance measurements. BRITISH INSULATED CABLES, Ltd., and CARSTEN, H. R. F. Oct. 16, 1941, No. 13342. [Class 37] Apparatus for measuring high-frequency electrical quantities by comparison comprise frequency changing apparatus arranged to deal with two electrical quantities at the same high frequency and reduce them' to the same lower frequency in combination with means for comparing the two quantities after frequency conversion. Fig. 1 shows an arrangement for measuring two voltages U1, U2, at the same high frequency, which are applied to the input terminals of two heterodyne frequency converters H1, H2. These have the same linear characteristics and are fed in parallel from a source O of local oscillation having a voltage' which is large compared with the voltage to be measured. At the output of the frequency converters two beat frequency voltages are obtained and are applied to fixed terminal resistances D1, D2, from each of which is tapped a voltage small in comparison with the total output. These voltages are applied to the primary windings P1, P2 of a differential transformer T having its secondary winding S connected to a telephone or visual indicator I. The differential transformer is balanced by varying the position of the voltage taps, from which positions the relative values of the voltages U1, U2 may be ascertained. Fig. 2 shows an apparatus for measuring the attenuation of a high frequency cable C, which is fed at one end from an oscillator OC and is terminated at the other end by a resistance Z equal to the characteristic impedance of the cable. The voltages U1, U2 at the feeding and distant ends of the cable are applied to the input terminals of the frequency converters H1, H2, a phase changer P being inserted between one of the converters and the corresponding end of the cable. This device consists of a short resonant line of variable length which has a very small and practically constant attenuation. From the converters H1, H2 the output voltages are fed into the primary windings P1, P2 of the differential transformer T through variable attenuators R1, R2. The secondary winding S is connected through an amplifier D and a detector to a measuring instrument I which indicates the attainment of balance. The converters H1, H2 are initially connected to the same point on the cable, the attenuators R1, R2 are set to about half scale. The converters are then connected to the voltages U1, U2 and a balance is obtained. The difference between the initial and final settings of the attenuator R2 indicates the attenuation of the cable. Impedances may be compared by comparing the currents through them or the voltages across them.

Abstract: 290,227. Aum³ller, E. May 10, 1927, [Convention date]. Drawings to Specification. Supplying consuming devices; charging batteries.-In a train-lighting system comprising a constant-speed turbo-dynamo and a battery on the train an electromagnetic switch is actuated when lights are burning to render a compound winding on the dynamo effective. Charging proceeds only when no lamps are on, and the electromagnetic switch, de-energized, then cuts out or short-circuits the compound winding and diminishes the resistance in the shunt field circuit so that full charging voltage is developed. A voltage relay may cause the illumination of a visual signal or the actuation of means to stop the dynamo when the battery is fully charged. The electromagnetic switch has two coils one energized when a lamp switch on the locomotive is closed and the other energized by a conductor passing through the train from which the train lights are supplied when a main switch is' closed.
