Abstract: 1382711 Cathode-ray tube circuits; analogue gating circuits SABA SCHWARZWALDER APPARATE-BAU-ANSTALT AUGUST SCHWER SOHNEV GmbH 18 May 1972 [27 May 1971 7 Sept 1971] 23311/72 Headings H3T and H4T In an arrangement for correcting NORTHSOUTH pincushion distortion in a cathode-ray tube television display by utilizing a field deflection waveform composed of a line frequency parabolic wave train amplitude modulated by field frequency sawtooth waves the deflection wave is produced by first deriving a train of line frequency square-wave pulses amplitude modulated by the field frequency sawtooth waves and then effecting successive integration steps to convert the square waves firstly, into line-frequency sawtooth waves and secondly into line-frequency parabolic waves. As shown in Fig. 4, line-frequency squarewave pulses and field (raster) frequency sawtooth waves are supplied to inputs D and E respectively of a modulator circuit which operates to clamp the field sawtooth at a level determined by the voltage set at point G (by potentiometer 14), during the occurrences of the line-frequency (fly-back), pulses, the clamping being effected via diodes 8 and 11 which are conductive during the first half of the field sawtooth and via diode 12 and transistor 9 during the second half of the field sawtooth to produce at point A the waveform shown in Fig. 5A. This is then supplied to a first Millar integrator comprising transistor 16, capacitor 17 and resistors 18, 19 and 20, the R.C. circuit 18, 21 providing high feed back at field-frequency and a H.P. filter comprising capacitor 22 and resistors 23, 24 ensuring attenuation of the field frequency so that only the line frequency square wave pulses in the waveform are integrated to produce sawtooth waves as shown in Fig. 5B. This voltage is fed to a "split-load" circuit comprising transistor 26, which also acts as an impedance transformer input to a second Millar integrator comprising transistor 27 capacitor 28 and resistors 29, 30 and 31 which integrates the sawtooth waves to produce the parabolic waveform shown in Fig. 5C. The latter waveform is then supplied via transistor 32, which acts as an impedance transformer input to a current feed back linear amplifier (not shown), which produces the required deflection current as shown in Fig. 2. Trapezoidal distortion may be corrected by deriving a signal from the potential divider 26.

Title: Improvements in and relating to protective systems for electric motors
IPC: H02H7/085
Filed: 1951-10-09
Abstract: 710,007. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON . CO., Ltd. Oct. 9, 1951 [Oct. 12, 1950], No. 23472/51. Class 38(5) In a protective arrangement for an electric motor, a bimetallic overload relay is heated in accordance with the motor current to provide an operating characteristic just sufficient to protect the motor under stalled rotor conditions, further delayed heating in accordance with a function of the applied voltage being provided to give adequate protection to. the motor under running conditions. In Fig. 1, a three-phase motor 1 is protected by two relays 9, 10 having bimetallic strips 13 heated by coils 14 connected in series in two of the supply leads. The heater coils 14 are arranged to heat the bimetals sufficiently for the bimetals to open their contacts 11, 12 under excess current due to stalled rotor conditions, whilst permitting the application of a somewhat lower excess current to the motor, sufficient for the motor to accelerate a large inertia load, without the opening of the contacts 11, 12 and the consequent opening of a contactor 4. When the motor is running, a centrifugal switch 16a connects heating coils 15 between two of the supply leads, the coils 15 providing additional heating for the bimetals 13, such that the relays 9, 10 become effective to open their contacts in response to a running overload condition. Instead of using a centrifugal switch to provide the delay in energizing the coils 15, a thermistor of a material, such as that described in Specification 682,887, may be used. Alternatively, a bimetallic switch 16<SP>1</SP>, Fig. 3, may be positioned for response to the motor frame or winding temperature and cause the energizing of the " voltage " coils after a delay. Fig. 3 shows an arrangement in which the induction-heated relay of Specification 541,418 may be used. The relays 9<SP>1</SP>, 10<SP>1</SP> have inductively-related coils 22, 23, the coils 23 being connected across like portions of the motor stator windings so that the current in the coil 23 of each relay may be substantially in phase with the current in the coil 22 of the same relay. In Fig. 4 (not shown) the switch 16<SP>1</SP> is omitted and the coils 23 are connected to an artificial neutral point, the ' limbs ' of the neutral point impedance being formed by the coils 23 in conjunction with an inductance connected to the third supply line. In this case the inductive coupling of the windings produces a bucking effect which delays the effective energization of the coils 23. Specification 557,190 also is referred to.

Heading G2A, A spring-biased driving disc 2 for a photographic shutter is released by operation of the lever 10 to open the shutter, which is held in this position by an arm 21a of a locking lever 21 engaging a projection 2b on the disc. The locking lever is pivoted by operation of an electromagnet 25 to close the shutter. The pivot 20 of the locking lever is arranged so that the line of force exerted by the disc on the lever passes through the pivot. Movement of the release lever 10 allows a lever 36 to close a contact 38 whereby the electromagnet 25 is energized to hold the locking lever in the operative position. After a delay determined by a variable resistor and a variable capacitor in a transistor circuit, the electromagnet is de-energized and allows the locking lever to move under its biasing spring 26 to allow the driving disc to close the shutter. In an embodiment the driving disc operates a bell crank lever which engages a projection on the locking lever.

Abstract: 1387042 Colour television ROBERT BOSCH FERNSEHANLAGEN GmbH 19 May 1972 [21 May 1971] 23705/72 Heading H4F A method is provided for balancing the white and black levels and the gamma characteristics of the colour channels of a colour television camera. To achieve white balance the camera views a white scene and the red and blue signals at 1, 3 are switched at 6 to pass sequentially to a rectifier 5 and difference circuit 8 which also receives a green (or white) signal from 2 via rectifier 4. The resulting signals are passed to control members 14d, 14e in amplifiers in the red and blue channels to reduce the difference signals to zero. For black balance, with the light to the camera cut off, all three signals, red, blue and green (or white) are applied to circuit 8 via sequential switch 6, signals from 8 being passed to control members 14a, 14b, 14c so as to make each of the signals received by circuit 8 from switch 6 equal to a reference voltage applied at 12. For gamma characteristics balancing the camera views a white scene under differing illuminations (e.g. by use of an adjustable diaphragm 20), e.g. 30%, 50% and 70% of maximum illumination and red-green (or white) and blue-green (or white) difference signals for each illumination are produced. For each channel (red and blue) the difference signals are summed at 13, gamma balancing in each channel being effected via control members 14f, 14g of respective amplifiers to reduce the sum of differences for that channel to a minimum. White, black and gamma balancing are selected by switches 16, 17, 18, depression of switch 18 causing white and black balancing to be effected before the gamma balancing. Automatic white balance may be achieved by the use of photo-cells viewing a white scene and providing signals corresponding to those which would be produced by the camera.
