IPC: H03L7/107
Filed: 1959-10-08
Abstract: 889,781. Automatic phase control systems. TELEFUNKEN G.m.b.H. Oct. 8, 1959 [Oct. 9, 1958], No. 34131/59. Class 40(5). In an automatic phase control system as described in Specification 875,893 loss of synchronism between pulses 14 derived from the controlled oscillator 3 and synchronising pulses 5 renders a coincidence and rectifying valve 10 for pulses 14 highly resistive so that, instead of its anode voltage being normally negative and making conductive a diode 9 forming part of a damping circuit 7 shunting the control filter 2 between the phase detector 1 and oscillator 3, the anode voltage becomes positive and the diode 9 becomes positively back biased and non- conductive so that the damping due to the filter 2 is reduced and the lock-in range of the system increased, e.g. from  100 c/s to 500 c/s, by the insertion in the shunt circuit 7 of a further series resistor 8, increasing the system sensitivity. The system conversely provides reduced sensitivity to noise and interference during synchronism. The pulses may be line flyback pulses of a television receiver. In a modification the pulses 14 and sync pulses 5 are applied to opposite sides of a rectifying diode in series with a load resistor in the lead connected to HT+ to derive, as in Fig. 1, a negative voltage blocking diode 9 during synchronism.

Title: Improvements in photographic sensitive material of the mono-pack type adapted for colour photography
IPC: G03C1/825
Filed: 1935-12-10
Abstract: 467,110. Colour photography. DEHN, F. B. (Omnichrome Corporation) Dec. 10, 1935, No. 34245. [Class 98 (ii)] A sensitive silver halide plate, film, or paper is converted into a monopack for colour photography by the application of a single solution containing colour sensitizers and filter dyes which diffuse into the emulsion layer at different rates, thereby producing in the layer several strata, each adapted to record a different colour. The solution may be applied as by spraying or coating to the surface of an already-coated emulsion, or to the surface of the support or of a gelatin layer coated thereon, before coating it with emulsion. An already-coated emulsion may be treated, before applying the sensitizing &c. solution, with a wetting and swelling agent, e.g. borax or an acid phosphate. In an example for tricolour work, the sensitizing solution contains in colloidal suspension as sensitizers, (1) Pinacyanol or Cyanine which diffuses slowly, and (2) Pinachrome, Erythrosine and Orthochrome T which diffuse at a medium rate ; and as filter dyes, (3) Rose Bengal which diffuses at a medium rate, and (4) Rapid Filter Yellow which diffuses quickly, all in stated proportions. After diffusion, the furthermost stratum contains only the filter dye Rapid Filter Yellow, so that it absorbs and records blue only ; the intermediate stratum contains Pinachrome, Erythrosine and Orthochrome T which sensitize it for green, and also Rose Bengal and Rapid Filter Yellow which serve as filter dyes in front of the third stratum ; and the third stratum contains Pinacyanol or Cyanine in preponderance over smaller quantities of the remaining ingredients, so that it records mainly red. Specifications 340,278 and 381,787 are referred to.

Title: Improved hydraulic control system for a variable-speed power transmission mechanism
IPC: F16H61/02
Filed: 1956-11-15
Abstract: 796,272. Change-speed control. GENERAL MOTORS CORPORATION. Nov. 15, 1956 [Dec. 9, 1955], No. 34932/56. Class 80 (2). Fluid pressure acting at 42 on alternatively actuated clutches and brakes in a changespeed gear under control of a manual or automatic shift-valve 40, is regulated to a reduced value during a shift interval by reducing the loading of a main pressure regulator valve 20 in response to the pressure differential across an orifice 36 in the servo line 38 supplying the clutches and brakes. Pre-shift stable condition, shown in Fig. 1, is disturbed when movement of the shift-valve 40 causes flow from a pump 11 through the servo line 38. The resulting downstream pressure drop created by the orifice 36 causes depression of a valve 48, closing a pressure port 58 and opening a restricted exhaust 64 to a line 62, which permits a piston 24 to descend and reduce the compression of a spring 22 loading the main regulator valve 20 controlling pressure in the pump delivery line 14. The regulated servo pressure is thereby reduced. Cessation of flow to the servo line 38, on completion of shift, eliminates the pressure drop across the orifice 36, permitting a spring 52 to restore the valve 48 to its upper position, shown, closing the exhaust 64 and opening the pressure port 58 for supply of line pressure 14 through a restrictor 56 and the line 62 to the piston 24 which rises to the position shown for increase of regulator-valve loading to its normal operating value. The rate of pressure decrease and increase is determined by the orifices 64, 56 respectively, elimination of either of which results in instantaneous pressure change. In Fig. 5, not shown, equal decrease and increase rates are provided by substituting for both restrictors 64, 56 a single restrictor in the line 62, such restrictor being adjustable as by the provision of a number of different restrictors on a controllable plate moved during the shift interval.

Abstract: 1,252,151. Direction finding. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. 16 Oct., 1959 [7 Nov., 1958], No. 35186/59. Heading H4D. A method of phase integration for the comparison of two signals of narrow bandwidth having random characteristics comprises transposing the central frequency of one of the signals to a second frequency, passing the transposed signal and the second signal through a quadratic detector, heterodyning the output of the detector with sine and cosine components of a local oscillator having a frequency equal to the difference between the central frequency and the transposed central frequency, integrating the two outputs, and applying them to the horizontal and vertical deflection plates of a cathoderay tube. The method may be applied to locating the sources of sounds by comparing the phases of signals received by two detectors. In Fig. 3 the outputs f 1 (t) and f 2 (t) of the sound detectors are fed to input amplifiers 31, 32 of the frequency changing type which isolate a band #F about a frequency F 0  which can be varied in the range 5 to 25 Kc/s., the filtering operation being carried out at the intermediate frequency F 0 <SP>1</SP>. The first signal f 1  is demodulated by two voltages in quadrature of frequency F 0 <SP>1</SP> and passed through delay lines 25, 26 which have a delay time which can be adjusted to be approximately equal to the propagation delay between signals f 1  and f 2 . The outputs of the delay lines pass through low pass filters 27, 28 to units 39, 40 where they modulate two signals in quadrature of frequency F 1 . The outputs of units 39, 40 are added in unit 11 and pass through an amplifier/filter 12 to unit 14. The output of amplifier 32 passes through filter 13 to a second input of the addition circuit 14, the output of which passes to a square law detector 15 and filter 16. From filter 16 the signal passes to two mixers 17, 18 where it is mixed with two voltages in quadrature of frequency F 2 . F 2  = F 1  - F 0 <SP>1</SP> and may be derived from F 1  and F 2 <SP>1</SP> in unit 23. The outputs of mixers 17, 18 pass to R.C. integrating circuits 19, 20 and D.C. amplifiers 21, 22 and then to the deflecting plates of a cathode-ray tube. It is explained in the Specification that if the input signals are f 1 (t) = a 1 (t) sin [2#F 0 t + # 1 (t)] and f 2 (t) = a 2 (t) sin [2#F 0 t + # 2 (t)], the output signals applied to the cathode-ray tube are the mean values of a 1 (t - #) a 2 (t) cos [# 1 (t - #) - # 2 (t)] and a 1 (t - #) a 2 (t) sin [# 1 (t - #) - # 2 (t)] where # is the delay in delay lines 25, 26. The phase difference between the input signals can be measured to an accuracy of 2 degree phase displacement, and the indeterminateness of multiples of 2# can be removed by varying F 0 .
