Title: Improvements in or relating to radio receivers for at least two very- and/or ultra-high frequency ranges
IPC: H03G3/22
Filed: 1953-02-27
Abstract: 724,951. Valve circuits for radio reception. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 27, 1953 [March 3, 1952], No. 5538/53. Class 40 (5). In a superheterodyne receiver on two ultrahigh -frequency ranges, local oscillations are generated on the higher frequency range by mixing oscillations from two oscillators respectively of fixed and variable frequency, while the variable oscillator alone is used on the range of lower frequency. On the higher frequency range oscillations from the variable-frequency oscillator 1 are fed into the fixed-frequency oscillator 4, which is tuned by means of a Lecher system 3 and which also acts as a mixer for the two oscillations. The beat frequency is fed via a filter 13 to a crystal mixer 18 to which the signal from aerial 21 is also applied. Intermediate-frequency oscillations from inductance 16, tuned by circuit capacity, are applied to the cathode of valve 14, which acts as a groundedgrid I.F. amplifier on this range. The output appears across an anode-circuit inductance 15 tuned by circuit capacity. For the lower frequency range switches 5-8 are reversed. Signals from aerial 22 are then fed to valve 14, which forms a grounded-grid R.F. amplifier coupled by tuned circuits 10, 11 to valve 4. This functions as a triode mixer, local oscillations being derived from oscillator 1 alone, and I.F. output appears across coil 15 which is now in the anode circuit of valve 4. On the higherfrequency range, a wider coverage may be obtained by making the Lecher system 3 adjustable or exchangeable.

Abstract: 1,169,365. Measuring mass fluid flow electrically. EVERSHED & VIGNOLES Ltd. Feb.6, 1967 [Feb.9, 1966], No. 5718/66. Headings G1N and G1R. Apparatus for measuring the mass rate of flow of a fluid comprises a movable, tapered member 3 Fig. 1 in the flow path, attached by strain gauges to a fixed casing 7, whereby the force exerted by the fluid flow, representing eV<SP>2</SP>, can be measured, a separate member (not shown) located upstream to measure velocity V, and means for obtaining the quotient eV representing mass flow. The tapered member 3 which is attached to the input conduit 1 by flexible sleeves 10, 11, has four holes 8 positioned where the pressure has a mean value. The force signal eV<SP>2</SP> and the velocity signal V are combined in the circuit of Fig. 3. A clock pulse generator periodically switches on a flip-flop F1, which opens a second flip-flop F2 for the period between two pulses from the velocity meter 12, i.e. a period proportional to 1/v. During this period the force signal eV<SP>2</SP> is fed to an integrator, which thus finds the average value of eV<SP>2</SP>x 1/v i.e. eV, the mass flow rate.
