Patent GB-1290719-A (GB)
IPC: H04N5/202
Filed: 1969-12-23
Abstract: 1290719 Colour television THOMSON CSF 23 Dec 1969 [27 Dec 1968 31 Dec 1968] 62700/69 Heading H4F [Also in Division G4] A circuit having a non-linear transfer characteristic, e.g. a gamma correction circuit, comprises an array of diodes D1, D2 &c. having different conduction thresholds adapted to provide a transfer-junction characteristic composed of straight line segments, and a further variable circuit B for modifying the shape of the characteristic. The diodes D1, D2 (two only shown) are inversely biased by different positive voltages V 1 , V 2  (V 2  > V 1 ) such that, as the signal E rises from a level E B  (0 volts) to a level E N , the diodes become conductive at break points C 1 , C 2  on the segmental characteristic shown (which may approximate a log junction). The diode circuit A may be incorporated into the collector, instead of the emitter circuit of transistor T. The circuit B comprises a source C of variable current I controlled by a variable potentiometer Rv. The current I is fed to the junction of two equal resistors R, R<SP>1</SP> which, together with diode D 3 , are connected in parallel with the circuit A. Diode D 3  starts to conduct at a value of E dependent upon the current I. The effect of two different values I, I 2  (I 2  > I 1 ) of the current I is shown by the curves 2, .3, Fig. 2, and it is apparent that the shape of the transfer characteristic may be continuously modified by adjustment of R V  A second diode D 4  connected as shown is inversely biased by a positive voltage V 4  such that it becomes conductive at a value of E = E 4  near the level E N , the diode D 3  then being conductive. As E approaches E N , the voltage V 3  on diode D 3  increases and the resistance of diodeD 4  diminishes. The increments of I are then distributed equally between R and R<SP>1</SP>. The potential V 3  remains practically constant for different values of I as E N  is approached, whereby the output S is practically constant at the level E N . The circuit therefore provides a variation in the shape of the characteristic whilst preserving constant limiting conditions. Colour television.-A separate channel is allocated to each of the three colours, red, green and blue (Fig. 4, not shown). Thus, the red signal X R  is applied as input to the circuit of the invention to obtain an output y R  = #γ R  log X R , where Aγ R  is the red gamma correction and is adjusted by potentiometer R v . This signal is applied to an attenuator which applies an attenuation equal to the value of a. general gamma common to all three channels. Finally, the signal is applied to an antilog circuit to obtain the signal x R #γR + γ, where γ is the general gamma. The green and blue channels are similar to the red. The three attenuators for application of general gamma are ganged to a common control, whilst #γ R , #γ v , #γ B are separately adjustable.

Abstract: 1295198 Snap-action switches; retractive switches CUTLER HAMMER INTERNATIONAL FINANCE Inc 19 April 1971 [26 Feb 1970] 24311/71 Heading H1N An electric switch comprises fixed contacts 8 and a movable contact 18 mounted on an actuating lever 14 pivoted on centre fixed contact 8 and resting at its top end in a sliding actuator 16 above which is a sliding drive block 26 moved by operating lever 6. Blocks 16 and 26 are linked together by a projection 26a a block 26 locating in recess 16a in block 16 and by a snap spring 28, Fig. 5. Spring 28 runs parallel to lever 14 to one side of it and is located in a recess 16b, Fig. 7 (not shown), in block 16, recess 16b having slots 16c, Fig. 7, opening into its ends, slots 16c being narrower than recess 16b. Fingers 26b. Fig. 5, project downwards from block 26, slide in slots 16c and engage opposite ends of snap spring 28. Also part of the snap action mechanism is a plunger 22, Fig. 5, parallel to actuating lever 14 and below snap spring 28, which has projections 22a locating in cam recesses in the underside of block 16, plunger 22 being urged upwardly by springs 24. The action is as follows. If operating lever 6 is pivoted clockwise, drive block 26 is slid to the left and projection 26a slides in recess 16a to take up the lost motion and simultaneously right hand finger 26b, Fig. 5, compresses spring 28. When the lost motion is taken up, projection 26a engages the end of slot 16a and slides actuator block 16 to the left camming down projections 22a on plunger 22. When projections 22a are depressed out of the cam recesses in block 16, block 16 is free to move and the left hand end of the compressed spring 28 bears on the end of the recess 16b, Fig. 7, and snaps block 16 to the left pivoting actuating lever 14 and movable contact 18 into contact with the left hand fixed contact 8. A return spring 30, Fig. 4, is provided. This is parallel to lever 14 on the opposite side of lever 14 to snap spring 28, and when block 26 is moved to the left it compresses spring 30, the left hand end of spring 30 bearing a flange 32a of pin 32 and thus being unable to move. When the operating lever 6 is released, the compressed spring 30 snaps block 26 back to its central position carrying block 16 and hence actuating lever 14 with it. If spring return is not required, pin 32 is omitted and plunger 22 retains blank 16 in position, projections 22a engaging further recesses in blank 16. The switch casing is sealed by sealing washers. The switch may have more than one pole, the extra contacts being located on the opposite side of lever 14 to snap spring 28.

Abstract: 1308897 Digital data storage KOMBINAT ZENTRONIK VEB 26 Jan 1971 3226/71 Heading G4C  In a system in which digital data pulses are recorded on a moving magnetic recording medium the pulses are supplied to the recording circuitry in a form in which each pulse has only one steep edge, e.g. as in Fig. 2a. In one embodiment the 1 and 0 pulses of this form are fed to inputs E1 E0 respectively, Fig. 1, of a differential amplifier V whose outputs A0, A1, control astable multivibrator M. The Markspace ratio of the multivibrator output signal therefore varies as in Fig. 2b, this signal being applied to the recording head K. The resulting remanence approximates to the waveform to Fig 2a. In a modification, head K is placed in the collector circuit of the multivibrator. The differential amplifier need not be used, and if the pulses, Fig. 2a, are polar the differential amplifier, or the multibrator, may receive the pulses via a single input.

Abstract: 1317547 Angular bending G V BYZOV I V VALDMAN B Y MAZUROVSKY and I E YAKIBJUK 1 June 1971 18328/71 Heading B3E A heat exchanger section, comprising a row of tubes lying in the same plane and passing perpendicularly through a plurality of flat parallel fins, is bent by longitudinally compressing the section to a critical state preceding the loss of stability by the tube material, and applying a bending moment to the ends of the tube by moving the section on to a former 4. In operation the tube ends are clamped in a holder 17 and a crosspiece 12, and the section compressed by moving a carriage 5 towards the former 4 and restraining the crosspiece 12 from pivoting about an axle 7 by a constant pressure hydraulic cylinder 8. When the critical state is reached, the force of the carriage 5 overcomes the force applied by the cylinder 8 so that the crosspiece 12 pivots about the axle 7 and bends the section to the shape of the surface 18 of the former. Damage to the section surface during movement of the section is prevented by the simultaneous movement of a metal strip 20 placed under the section, the strip having one end fastened to a tension device on the axle 7 and the other end to a spring 22 mounted on the carriage 5. After bending the section to a radius R 1 , a support 13 is pivoted about an axis 16 to bend the section on the former 4 to a radius R 2 . (For Figure see next page)

Abstract: 1318228 Change-speed gear-box pneumatic control BRITISH LEYLAND TRUCK & BUS DIVISION Ltd 21 Jan 1972 [26 Jan 1971] 3130/71 Heading F2D Gear selection is inhibited in a gear-box in which pneumatically operated friction elements effect gear change until a predetermined pressure is present in the system sufficient to effect gear engagement without wear to the friction elements. In an electropneumatically operated gear-box the electrical circuit to operate solenoids to effect actuation of friction elements for gear engagement is rendered inoperative until the system has sufficient pressure to close a pressure sensitive switch. The circuit is such that the selection lever must not be moved from the neutral position until the pressure switch is closed if gear engagement is to be effective. In a wholly pneumatic system a pressure regulator is provided which remains closed to render the selector valve ineffective until the necessary pressure is reached in the system. In both examples a warning is sounded as the pressure falls towards the predetermined value and when this is reached all gears are disengaged.
