Yarn, wire and the like is classified by measuring its diameter photo-electrically and analysing diameter variations according to length and magnitude of variation. The yarn under test, 10 passes in front of a photo-cell to give an output indicative of diameter. The output is compared with the output of a second cell which has before it an adjustable shutter whereby a nominal diameter is set. The difference output from unit 11A is fed to a meter 14 having limit contacts 15 which operate either a yarn cutter 12 or recorders 16 for over- and under-nominal yarn diameter. The difference signal is also applied to threshold gates 19, 22 which emit signals at different degrees of overweight yarn and also for yarn of more than 50% underweight. Faults in yarn diameter of +50% or more classified for length by timing circuits B, C, D, E and F. A pulse at the start of the fault is fed to circuit B to open the associated gate for a preset-time. At the end of this period the gate is closed and a pulse passed to circuit C to open its gate for a preset time and so on for the other timing circuits. A trailing edge pulse for the fault passed through which ever gate is open to be registered on a corresponding counter 25. The outputs of threshold circuits 19, 22 may be monitored on a cathode-ray tube 18 or aural warning system 23.

Abstract: 1429569 Time switches AMF Inc 24 July 1974 [11 Sept 1973] 42762/73 Heading H1N [Also in Division H2] A system for defrosting a refrigerator comprises a switch 12 having four blades 12A-12D, certain of which blades carry contacts 13-16 and which are operable by cams 18A-18D carried on a shaft 18E, the cams 18 being moved in a first instance by an adjustable tappet 21 secured to the dial 22 of a time clock driven through gearing 24 by a motor 23, which tappet 21 co-operates with a cam 17 on the shaft 18E, the first movement of the cams 18 causing the blades 12 to move so that the compressor and fan motors are switched off and the defrosting heater switched on. When the refrigerator is sufficiently defrosted an electric motor is energized, which, by way of gearing 26 drives a cam 27 and eccentric pin 28 to move a lever 30 about a fulcrum 31 to cause a pawl 34 to move  the cams 18 so that the blades 12 are again moved whereby the compressor motor is switched on and the defrost heater switched off. The cam 27 operates a microswitch 37 so that the electric motor is switched off after the pawl 34 has moved the cams 18. After a given time the electric motor is again energized whereupon the pawl 34 is again moved to again operate the cams 18 and the blades 12 whereupon the fan motor is reconnected. The tappet 21 is provided with a member 40 which co-operates with a cam 17A on the shaft 18E to terminate the defrost operation should any failure of the mechanism occur. In a further embodiment the electric motor operating the lever 30 is replaced by an electromagnetic solenoid (49, Fig. 7, not shown) which when energized causes operation of a clutch member so that the motor 23 causes the further movements of the cams 18 by way of a worm-wheel (51) fixed thereto.

Filed: 1972-09-18
Abstract: 1407498 Television ELLANIN INVESTMENTS Ltd 18 Sept 1972 [30 Sept 1971] 43177/72 Heading H4F To improve the resolution of a reproduced television image in an electron-sensitive motion picture film recorder or a television luminous display, the scan velocity of the intensity controlled electron beam is modified as a function of variations in the beam intensity control signal i.e. the video signal, so that substantially instantaneous black-to-white and white-toblack display transitions are produced. The scan velocity variation signal may be applied to the electron beam by way of an additional pair of horizontal deflection plates, although it may be superimposed on to the horizontal sweep signal. In the embodiment described a motion picture film is produced from a video tape signal Y 0 , the scan velocity variation signal H<SP>1</SP> being produced by delaying Y 0  three times by 60 ns., the resulting delayed signals Y 1 , Y 2 , and Y 3  being subtracted from each other and from Y 0  as shown in Fig. 2 by means of comparators 36 and 38 to produce difference and inverted difference signals. Diodes 44-50 are arranged to pass the most negative (or least positive) of these signals to clippers 40, 42 which pass only the positive portions thereof via adjustable non-linear amplifiers 52, 54 to adder 58. The signal H<SP>1</SP> has an abrupt change of slope at its peak during each amplitude transition of the signal Y 0 , this signal Y 0  being delayed 64 (together with the horizontal sync signals Ho) to produce a Y<SP>1</SP> signal whose transition midpoint is coincident in time with the peak of the H<SP>1</SP> signal. The amplitude of the peak of the H<SP>1</SP> signal and thus the sharpness of the transition may be adjusted by varying the gain of the non-linear amplifiers 52 and 54 preferably until the electron beam just stops at the transition. The black-to-white and white-to-white transitions are displaced from the midpoint of the Y<SP>1</SP> transition and from each other which results in narrowing of light-coloured objects and widening of dark coloured objects. This displacement may be compensated by introducing an adjustable delay 56 between amplifier 54 and adder 58 and by increasing the delay of adjustable delay device 64 by a like amount. If the transition time of the Y 0  signal is greater than 120 ns. and thus does not represent an edge in the original scene, the above arrangement does not operate to create a sharp edge in the reproduced image.

Title: Linewise scanning an image area and processing the output of a scanning device

Filed: 1975-10-22
Abstract: 1528991 Scanning systems; target tracking systems CONTRAVES AG 22 Oct 1975 [25 Oct 1974] 43454/75 Headings H4F and H4D In an apparatus for providing an output signal which has an improved signal:noise ratio relative to that of an input image signal the image signal is derived by line-by-line scanning of an image field such that part of the field is sensed during more than one scan line, the scan lines occupying positions angularly spaced about the centre of the field. The signal from the detector which scans the field passes to delay means to provide at least two signals delayed with respect to one another. These signals are combined with a signal representing the position along the scan line of the instantaneously scanned area of the field to provide further signals which are combined to form the required output signal. The various signals may be digital. The detector may form part of a target-tracking system and sense infra-red, laser light, or microwave radiation. It or reflectors may be moved to provide the scan, or the image field may be illuminated by radiation scanned over it. As disclosed the image field is circular and each scan line has a width d and extends diametrally across the field. Adjacent scan lines are angularly displaced such that they just do not overlap at the periphery of the field. Image points which are not on the periphery may therefore be sensed during more than one scan line. In one arrangement, Fig. 2 (not shown), the detector output f(t) is fed to a series of N - 1 delays, where N is half the number of scan lines in the field. Each delay is equal to the duration T of one scan line. The outputs of the delays and the signal f(t) pass to respective multipliers where they are multiplied with signals which are the product of a ramp function and the position-indicating signal r(t), here the instantaneous distance of the detector from the centre of the scan pattern. The sum of the outputs of the multipliers is the required output signal F(t). Instead of using series-connected delays parallel delays may be used, the delays having values T, 2T, 3T, etc. In another arrangement, Fig. 3 (not shown), the input signal f(t) is fed only to one multiplier. A second multiplier is fed with the output signal F(t) delayed by T, signal F(t) being the sum of the outputs of the two multipliers, which are also fed with signals dependent on r(t).
