C. signal, such as the output from an electro-manometer used in respiratory testing of animals, relative to a D.C. reference level is eliminated by a circuit arrangement in which the signal is biased to an extent ensuring a negative going portion, the negative going portion is inverted, the peak value of the inverted signal is stored, and the stored signal is added to the original signal together with a component removing the original bias, to restore the reference level. The signal is amplified, inverted, and the negative going portion selected in the amplifier and circuit arrangement 302, Fig.3a, the bias being developed across a resistor 316 and the selected output being stored in capacitor 318. When the negative potential of the input signal overcomes diode 340, Fig. 3b to which it is applied via resistor 333 amplifier 332 terminals 305, capacitor 38, and amplifier 339, a pair of flip-flops 349, 350, and 356, 357, are actuated in succession to produce pulses A and B which effect the transfer of the stored signal from capacitor 18 to a capacitor 320 by which it is applied through FET 321 to the adding amplifier 332, and reset the storage circuit by partially discharging capacitor 318, respectively. The pulses A and B may also be used to reset an integrator in a measuring circuit and to effect a recording of the integrated value. In the respiratory test described the effect of a broncho strictor agent is determined in an arrangement in which lung 104 Fig.1 is inflated by a constant volume pump at a constant pressure determined by bubble device 106 and the air overflow is determined by a photo-electric micro-manometer 109.

Title: Closing hydraulic turbines
IPC: F03B15/18
Filed: 1955-01-13
Abstract: 764,132. Hydraulic turbines. ESCHER WYSS AKT.-GES. Jan. 13, 1955 [Jan. 25, 1954], No. 1093/55. Class 110 (3). [Also in Group XXIX] In the event of a sudden removal of load the guide vanes are closed rapidly to a third of their total regulating movement, the turbine reaching zero output at a substantially increased speed. The runner vanes are then closed slowly and the guide vanes are closed in such relative relationship that the turbine continues to run for some time at a speed exceeding the idle-running speed and thus deals with a rate of flow in excess of the steady idle-running rate. The control is effected by a speed governor 1 coupled by a control lever 2 to a control valve 3 and a servomotor 4 which operates the guide vanes. A further servomotor 5 operates the runner vanes and is controlled by a valve 6 slowly supplied with liquid through a diaphragm 10. The servomotors and the valve 6 are interconnected by a link 7. The servomotor 5 also operates a cam 8 to displace a sliding block 9 which limits the lift of the governor.

Title: Radio diversity receiving system
IPC: H04B7/08
Filed: 1957-01-11
Abstract: 810,698. Automatic phase control systems. STANDARD TELEPHONES A CABLES Ltd. Jan. 11, 1957 [Feb. 14, 1956], No. 1148/57. Class 38 (4). [Also in Group XL (c)] In a radio diversity receiver the signal from two antennas 1, 2 are maintained in phase synchronism for maximum additive effect by automatically adjusting a phase shifter 13 preceding one input to the combiner 7. This may be done by amplitude modulating one input to the combiner 7 by a modulating frequency from source 6 so that, if the inputs are not in phase, the combined output is phase modulated at the frequency 6 and the latter may be detected by a frequency discriminator and filter 10 giving a variable-phase output of frequency 6 and of phase sense dependent on whether the input 4 leads or lags in phase the input at 3, which retroactively controls the phase shifter 13 until the inputs to the combiner 7 are cophasal. The modulator 5 may be a rotating variable attenuator or a ferrite modulator with attenuation dependent on an applied magnetic field. The combiner 7 may be a hybrid circuit or simple T-junction. The frequency 6 may be a frequency, e.g. 3500 c/s., in one of the guard bands of frequency multiplex telephone channels frequency modulated on a carrier, or for television, a frequency above the video band. In a modification the frequency 6 phase or frequency modulates the input 3 to produce from the combiner 7 an amplitude modulated output detected at 9 by an amplitude detector, the polarity, i.e. phase sense, of the detected output of frequency 6 being dependent on whether the input 4 leads or lags the input 3, as before its phase being detected by a phase discriminator 11 having a reference input from the modulating source 6. In a further modification the phase or frequency modulation is applied to a local oscillator beating with the input 3 and the output of phase detector 11 applied to adjust the phase of a second local oscillator beating with the other antenna input 4. In a still further modification a single local oscillator is used, its input to one mixer being frequency or phase modulated to produce from the combiner 7 an amplitudemodulated wave whose amplitude-detected output is compared in phase as before with the reference source 6 in a phase discriminator and its output applied to adjust a phase shifter between the local oscillator and the mixer for the other antenna input.
