Abstract: 204,433. Juhlin, G. A., and Metropolitan-Vickers Electrical Co., Ltd. July 7, 1922. Pole-pieces.-The pole-cap of a salient-pole rotor is attached to the polar projection by means of a dovetail joint extending along the pole, and the parts are provided with mutually engaging spigots or projections so as to strengthen the portions weakened by the provision of the dovetail groove. The pole-cap 4, Figs. 1 and 2, consisting of plates or laminµ, has a groove 6 in which engages a dovetail 5 on the core 2. The core has projections 16 engaging with projections 17 on the cap, which although normally weakened along the centre line 15, is correspondingly strengthened. In a modification, the dovetail is formed on the cap and fits into a groove on the pole, and the arrangement of projections 16, 17 shown in Fig. 2 is reversed. The end plates 7 supporting the polecap and coils are formed with projections 11, which are held by projections 10 on the pole 2. Flanges 14 may also be provided to support the coil.

Abstract: 1299747 Variable capacitance diode tuning PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 20 April 1970 [22 April 1969] 18834/70 Heading H3Q In an input stage for a radio receiver having input and output resonant circuits tunable by variable capacity diodes 3, 3<SP>1</SP>, an aerial input 1 is coupled through a variable capacity coupling diode 2 to the input resonant circuit, the output of the input resonant circuit is coupled to the output resonant circuit through a further variable capacity coupling diode 2<SP>1</SP> and the capacitances of the variable capacity coupling diodes 2, 2<SP>1</SP> are varied in the same sense during tuning as those of the tuning diodes 3, 3<SP>1</SP>. In the car radio receiver shown for reception in the medium wave the tuning voltage has a component U A  applied as a cut-off voltage to the coupling diodes 2, 2<SP>1</SP> and a component U N  for fine tuning which is applied together with U A  to tune the diodes 3, 3<SP>1</SP> so as to compensate for temperature fluctuations. To obtain the required signal to noise ratio the control range of the coupling variable capacity diodes 2, 2<SP>1</SP> may be limited by shunting each of these diodes 2, 2<SP>1</SP> with a constant capacitor or by reducing the cut-off voltage U A  relative to the tuning voltage U A +U N  by using a potential divider. Synchronism between the input and output circuits and the oscillator circuit controlling the mixer stage can be obtained by making the oscillator circuit equal to the input circuit and having the required frequency difference provided by a padding capacitor.

Title: Phase and frequency correction system
IPC: H04N5/95
Filed: 1966-05-03
Abstract: 1,120,752. Automatic phase control systems. RADIO CORPORATION OF AMERICA. 3 May, 1966 [17 May, 1965], No. 19592/66. Headings H3A and H4A. In a system for correcting frequency and phase errors in a television video signal reproduced from a magnetic recording in which periodic phase errors between the line synchronizing pulses and a reference signal are determined in order to produce an error signal which is used to control a variable delay system, an arrangement is provided which responds to the error signal and changes the error signal during the period between synchronizing pulses to change the error signal from a step function signal into a smooth signal. The system is applied in the reproduction of a magnetically recorded television signal in which the signal is recorded transverse to the length of the tape with, e.g., 16 lines of picture information being recorded on each traverse of a head across the tape. Phase and frequency errors are produced if the tape, which is stretched over the record and replay heads, is stretched more in replay than in record or vice versa. The first synchronizing pulse of the sixteen lines recorded across the tape will be in the correct phase, but each following pulse of the sixteen will deviate in phase by a greater amount. In the prior art compensating system, comprising elements 20 to 26 of Fig. 5, line sync. pulses are separated from the video signal from the recorder and are used to sample a sawtooth waveform which has a repetition frequency equal to the average line sync. frequency. Variations of phase appear as discrete voltage at the sampler output and are fed into the capacitor 25 to store the voltage between samples. The resulting signal controls the variable delay 20 so that the sync. pulses are restored, at the output of the delay, to the correct phase relative the reference sawtooth waveform from source 24. The system described above does not, however, correct the phase error introduced during the period between sync. pulses, being zero at the start of each line and a maximum at the finish, this phase error is unimportant in monochrome pictures but leads to a substantial error in hue in the colour television signals. The invention takes the error signal from capacitor 25 and filters off, in filter 50, a component of the error voltage. This component is sampled at its maximum value and applied, via a gain control, to control a current source feeding a current into capacitor 25 to provide correction of phase error during the line. The filter either selects the component corresponding to a complete passage of a reproducing head across the tape, so that the correction current is proportional to the total phase error after 16 lines, or the filter may select the line frequency component, so the correction current is proportional to the phase error occurring during one line.

Title: Improved means for regulating or controlling the calorific value of mixed gases
IPC: G01N33/22
Filed: 1931-07-09
Abstract: 383,654. Mixing fluids in flow. WALKER, C. B., 38, South Bar, Banbury, Oxfordshire, and WRAITH, H. O., 82, Victoria Street, London. July 9, 1931, Nos. 19739 and 24504. [Class 86.] The calorific value of a combustible gas is controlled by supplying it to an internal-combustion engine driving an electric generator which operates a device for controlling the calorific value. The amount of oxygen or carbon dioxide in a gaseous mixture may be ascertained in this way, provided the amounts of the other constituents are known. The gas from a main G is passed by pipe g through a temperature regulating water jacket C to which is also supplied air from an inlet A, a valve M controlling the proportions supplied to an internal-combustion engine E which drives a generator D. The leads from the generator are connected to a load-regulator L. The instruments are calibrated by using gas of a known calorific value from a container B. The calorific value of the gas is controlled by the use of a centrifugal governor N which actuates a two-way switch n, whereby either of two coils r, r<1> of a motor R may be cut in to cause rotation of the armature in opposite directions, which actuates a screw to move a double coned valve V to admit gases from the pipes X, Y in different proportions, one gas supply being of lower calorific value than the other.
