Title: Improvements in or relating to measuring system
IPC: G01F23/26
Filed: 1953-11-26
Abstract: 745,867. Electric measurements. LIQUIDOMETER CORPORATION. Nov. 26, 1953 [Dec. 5, 1952], No. 32837/53. Class 37. Apparatus of the type described in Specification 695,074 wherein the weight of liquid in a tank is determined by modifying the measured volume of liquid in accordance with the density on the basis of a fixed relationship between density-and dielectric constant, is characterized by the addition of further calibrating potentiometers to enable the measuring device to be used with different types and sizes of tanks. The electrical circuit (Fig. 1) comprises a number of A.C. fed potentiometers 48, 42, 30, respectively feeding the measuring capacitor C52, a parallel combination of a fixed capacitor C56 and a reference capacitor C58 completely immersed in the liquid being gauged, and a fixed capacitor C34, the other side of each capacitor being connected to a common point 36, whose voltage is fed to an amplifier 62 to drive a 2-phase motor 66 coupled to the slider 54 of potentiometer 42 to eliminate the voltage at 36, whereupon the balance position of the slider 54 is indicative of the weight of liquid gauged by capacitor C52, and is shown on a counter type indicator 74 attached to motor 66. A scale 76 also attached to potentiometer 42 indicates the weight of liquid in the tank as a proportion of the maximum weight of liquid the tank can hold. It is mathematically shown that to accommodate different installations the product of the voltage tapped off from potentiometer 30 and the capacity of 034 must be equal to the product of the voltage tapped off from potentiometer 48 and the capacity of C52 empty. For convenience a scale 82 is associated with potentiometer 48 to facilitate adjustment of this potentiometer for different values of C52 empty. Preliminary adjustments are made on a potentiometer 38 when the tank is empty and a potentiometer 46 when the tank is full. Specification 693,600 also is referred to.

Title: Improvements in or relating to mains-hum-reduction in apparatus for transmitting electrical oscillations
IPC: H03C1/06
Filed: 1946-11-06
Abstract: 625,063. Wireless transmitting apparatus. PHILIPS LAMPS, Ltd. Nov. 6, 1946, No. 33045. Convention date, Nov. 9, 1945. [Class 40 (v)] A hum compensating arrangement for use in mains fed transmitting apparatus, comprises means for recording the hum produced during the absence of modulations to be transmitted, the recorded image being used to provide opposition signals during normal transmission. 1, A microphone amplifier 5 feeds into a low-frequency amplifier 2, the output from which, together with that from oscillator 1, is fed to modulator 3. When the transmitter is operative, but with microphone 5 disconnected by switch 6, the output consists of a hum modulated carrier wave which is supplied to a detector 7, the output hum voltage therefrom being recorded on endless band 11 driven by a synchronous motor 10. When microphone 5 is in circuit, a negative feedback voltage from the recorded image is applied to amplifier 2 by operation of switches 8 and 14. Collecting device 12 is adjustable to control the phase, and potentiometer 16 regulates the amplitude ; filter 15 corrects amplitude and phase distortion, so that the feedback voltage may be adjusted to give correct compensation. The arrangement avoids distortion of low-modulating frequencies, which occurs if the hum frequencies are merely selected by a filtering arrangement and then used to provide negative feedback. The invention may also be applied to transmitters not using a carrier wave.
