In apparatus for investigating the hysteresis loops of ferromagnetic materials of the type in which a measure of the current supplied to an exciting coil is fed to the horizontal sweep input of an oscilloscope 4 and to the X input of an XY plotter 6 and the voltage induced in a sensing coil is, after integration 3, fed to the vertical deflection input of the oscilloscope and to the Y input of the plotter, the frequency of the input signals to the plotter is effectively reduced by sampling circuits 5, 7 which sample and store the values of the input signals to the oscilloscope at progressively varied parts of the excitation cycle under the control of a gating input signal derived through a variable delay circuit 8. Low frequency spurious signals are cancelled out by cross feeding through connections 41, 61 so that the vertical and Y inputs are controlled by the difference between the direct and sampled signals. The output of sampling circuit 5 is also connected through a low pass filter 9 to a second input of the integrating amplifier 3 to avoid saturation thereof, there being an odd number of phase reversing stages between the second input and the output of the integrating amplifier. The apparatus is suitable for measuring the hysteresis loops of magnetic thin film storage elements.

Abstract: 1434120 Pipe couplings; pipes INSTITUT FRANCAISE DU PETROLE 19 Nov 1973 [21 Nov 1972] 53619/73 Headings F2G and F2P A rigid coupling is secured to the end of a flexible pipe comprising a tubular core surrounded by at least one helical armouring by resiliently deforming inwards the core, cutting the armouring across its cross-section in the area of the inward deformation, removing the deformation and placing the pipe end in an annular space of the coupling to which solidifiable material is introduced. An inner plastics, &c. tubular core 2, Fig. 1, of a pipe 1 is surrounded by an armoured layer 3 of helically wound metal strip, wire, &c. The end of the armoured layer 3 is cut back (see Fig. 5) so that its axial spacing from the end of the core 2 is the same as the spacing of bores 23, 12, Fig. 6, in a coupling 11. The internal diameter of the bore 12 is somewhat greater than the external diameter of the armouring 3. The end of tubular core 2 is clamped between frusto-conical surfaces of the bore 23 and of a lock ring 24. A support ring 13 is temporarily placed inside the core 2 adjacent the end of the armouring 3. A fluid which subsequently sets is then introduced through a passage 15 to the bore 12, to seal the coupling; after the fluid sets, the support ring 13 is removed. The fluid which sets may be a metal alloy which melts at a sufficiently low temperature as not to damage the plastics core 2, or an epoxy resin, &c. As shown, the armoured layer 3 is in turn surrounded by a double layer 5, 6 of helically wound wires in turn surrounded by a plastics cover 7. The double layer 5, 6 is clamped between tapered surfaces 25, 26 of the coupling 11 and the cover 7 between tapered surfaces 21, 22. A fluid which subsequently sets, and which may be the same as the previous fluid, is injected through a hole 28 to an annular space 27 to seal the coupling. As a modification, a passage may connect the space 27 to the box 12, and the passage 15 omitted, so that both sealing functions are effected simultaneously by injecting through the hole 28. As shown, the armouring 3 is of Z- cross-section, Figs. 5, 5A. To cut the end off the armouring 3, the core 2 is indented. The final coil 9 is wholly severed by an axial sawcut, and the previous coil 10 is partly severed. The indentation of the core 2 is then removed.

Abstract: 1282133 Automatic control of rolling ISHIKAWAJIMA-HARIMA JUKOGYO K K 7 Nov 1969 54758/69 Heading G3R Variations in the shape of an illuminated line across the width of material being rolled are detected and utilized to adjust the pressure between the rolls across the width of the material to correct variations in the shape of the material being rolled. In Fig. 2, a beam of light from a source 12, or a number of sources in a line, is projected to form an image 13 across rolled material 10 ahead of or behind rolls 17, 18. The image is scanned by a TV camera 14 and signals corresponding to the longitudinal position of the image at three points 1, 2, 3 across its width are derived from the camera output at 1a-3a, sampled at 1b-3b, and compared with desired positions corresponding to a straight image at 1c-3c. Any non-linearity of the image and hence distortion of the material in the central area produces an error signal at 2c which is amplified at 2d and applied to correct the distortion by adjusting a valve 2e varying the pressure in hydraulic cylinders A 1  A 2  between roll 17 and a back-up roll 19. Similarly any distortion of the material at the edges produces an error signal at 1c or 3c which is amplified at 1d or 3d and applied to correct the distortion by adjusting a valve 1e or 3e varying the pressure in a hydraulic cylinder B 1  or B 2  between the work rolls. In a modification, deviation of the line at any of three positions is detected by photo-transistors responsive to light from the line or from an image produced on a TV monitor screen such as 15. In the former case photo-potentiometers may be employed and in the latter the error signals modify the datums of pressure controlling servo-systems associated with the hydraulic cylinders.
