Title: Vertical casting
Inventor: VIVES CHARLES
IPC: B22D11/115
Filed: 1985-09-17
Abstract: In a continuous vertical casting operation carried out in a mould 3, a coil 7 applies a periodic magnetic field of variable strength whose direction is substantially parallel to the axis of the mould 3 to the liquid 5 as it solidifies, in order to regulate the level of the line of contact of the free surface of the metal 5 with the mould 3. The height of the contact of the metal with the mould can be reduced from h1 to h2 by applying the magnetic field, and the strength of the field is adjusted in dependence on the desired level. The procedure is used in casting semifinished metallurgical products, in particular in aluminium and its alloys, in which there is a wish to obtain a cortical region of zero thickness, a fine grain without the preliminary addition of refining agents, and an absence of pitting.
Patent GB-2181547-A (GB)
Title: Acoustic direction detector
Inventor: GLASGOW JOHN ARTHUR
IPC: G01S3/808
Filed: 1985-10-14
Abstract: Signals from an array of four or more acoustic sensors A, B, C, D, E are inspected in pairs (at 7) to measure the delay in the time of arrival of a signal between each sensor of a pair. The validity of each delay measurement is then checked in logic circuit 13 by adding the measured delay values around different selections of three or more sensors. When the result of addition is zero, as it should be, all the appropriate delay measurements are assumed to be correct and are processed at 10. Any faulty measurements are repeated and the correct measurements alone are used to calculate the direction of the source of the signal. <IMAGE>

Patent GB-2191644-A (GB)
Title: Optical signal processing
Inventor: BYRON KEVIN CHRISTOPHER
IPC: H04B10/50
Filed: 1986-06-07
Abstract: An optical signal, which may be the output of a gas laser (1) which is not readily modulated, is modulated in a required manner with the aid of the Kerr effect. An optical beam output, for example from a semiconductor laser (4), which is modulated in the required manner is launched into a polarisation maintaining optical fibre (3) together with the optical signal output of the gas laser (1). The modulated optical beam is such as to induce the Kerr effect in the fibre in a manner corresponding to the modulation e.g. pulsed, and thus to induce corresponding polarisation variations in the beam from the other laser (4). The output of the fibre corresponding to that of the first laser is thus modulated in the required manner. To reduce the requirements on the semiconductor laser for high rate arrangements, a plurality of semiconductor lasers may be used, each suitably modulated and time division multiplexed together (Figure 2 not shown). <IMAGE>

Title: Inspecting an object having at least a portion with an axis of symmetry
Inventor: YOSHIDA HAJIME
IPC: G01B11/02
Filed: 1986-10-29
Abstract: A method and apparatus for inspecting the external shape of a nominally symmetrical object, or an object having a nominally symmetrical portion, employs a photoelectric conversion sensor which produces a video signal that is processed by an electronic processor to determine the goodness or badness of the object. An image 6 of the object is formed on a photoelectric screen with respect to XY coordinates, the photo-sensing being such that the assumed axis of symmetry is parallel to one axis of the XY coordinates. On the basis of the video signal, coordinates are obtained at a plurality of right and left points (XL1, Y1, XR1, Y1...X26, Y6; XR6, Y6) which occur where the external contour of the image 6 intersects a plurality of straight lines (Y1...Y6) perpendicular to the axis of symmetry. The right and left coordinates are used to derive the coordinates of a plurality of centre points (X1Y1...X6,Y6). A maximum frequency coordinate, designated as a standard centre coordinate (X5, Fig. 4) is then derived from the coordinates of the centre points. The standard centre coordinate is then compared with each of the plurality of centre coordinates to determine the goodness or badness of the object. Alternatively the distances between each of the left and right points and the standard centre coordinate can be compared.
