Title: Method of and/apparatus for oscillation amplitude measurement
IPC: G01D5/26
Filed: 1974-04-05
Abstract: 1471372 Measuring displacement photo-electrically OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES 5 April 1974 [6 April 1973] 15276/74 Heading G1A Vibrational characteristics of a body are monitored by detecting light reflected back from a retroreflector attached to the surface of the body. As shown in Fig. 1, light from source S is directed via a rectangular diaphragm D and semireflector T on to an area larger than retroreflective area E, which may be of strip or paint form or a single bead retroreflector. Contrast may also be improved by viewing reflected light through polarizing filters. The light passing a knife-edge C is monitored by a photo-detector R, whose output is indicative of displacement from a datum. By turning the knife edge at right angles to its first  orientation, two co-ordinate components of the displacement vector for the surface may be obtained, Fig. 4 (not shown). By use of a further optical system to produce a further reflected beam at right angles to the first reflected beam, the third vector component may be obtained. The second knife edge may be rotatable through 90 degrees, for a double check on one of the first components. By providing a beam-splitter, two knife edges at right angles may be used simultaneously, Fig. 5 (not shown). An alternative lens arrangement to the Fig. 1 embodiment may be provided, Fig. 7 (not shown). The knife edge may be oscillated in its own plane to effectively follow vibrations of the object and the drive current therefor monitored as indicative of these vibrations. A Piezo-electric strip one of whose edges acts as the knife-edge is suitable for this purpose. In an embodiment utilizing a photo-multiplier as the detector, an aperture w is provided in a plate located between the photocathode and the dynodes. Feedback current to deflection coils is measured as the edge of the cross-section of the electron beam is maintained located at the centre of the aperture w. If the direction of a displacement is already known, projector and receiver telescope may be located at right angles to one another, and the actual displacement measured. In a further embodiment, instead of a knife edge, a grating is located in front of the detector, Fig. 14 (not shown), and as the surface of the body S moves, the reflected light spot moves across the grating and produces a pulsating output. This grating may be a film or foil, formed as an endless loop, which is moved continuously in front of the detector, Fig. 16 (not shown).

Title: Improvements in or relating to the production of mats or the like of mineral wool
IPC: D04H1/00
Filed: 1957-05-16
Abstract: 822,528. Treating fibres. ROCKWOOL, A. B. May 16, 1957 [May 23, 1956], No. 15575/57. Class 120(3) [Also in Groups VIII, XXXVIII and XL(b)] In apparatus for producing flat formations of mineral fibres by feeding the molten mineral to a spinning machine and thence to a movable conveyer where the fibres are compressed to a mat, the speed of the conveyer is controlled in accordance with the power consumed by the spinning machine so that variations in the density of the mat are reduced. In Fig. 1 molten material from the furnace 18 falls on to the spinner 22 where it is broken up into fine drops by wheels driven by motors 24, 25. The drops solidify into fibres during passage through the air and fall on a moving conveyer 38 where they are compressed by the roller 39. Binder for the fibres is supplied by the pipes 43, 44 from a pump 45, and both the driving motors 33, 46 are controlled by the unit 31 in accordance with the power consumed by the motors 24, 25, i.e. in accordance with the weight of the fibres thrown off by the spinner 22. Thus the weight of fibres per unit length on the conveyer is kept constant. In the control unit (Fig. 2) a transformer 49 in the input lead to the spinner motors gives an output dependent on the power taken by the motors and positions a vane 53 accordingly; light from the source 60, 61 is thereby prevented from reaching the photo-cells 58, 59. When the power taken by the spinner motors increases or decreases one or other of the photo-cells develops a voltage which overcomes the bias 64 and allows one or other of the valves 62, 63 to conduct. The appropriate relay 65 or 66 is then energized and supplies current to the field winding 69 of the motor 67 to rotate it in one direction or the other. The motion is communicated to the selsyn transmitter 71" and reproduced at the receivers 73, 75. The first of these moves the photo-cells and light sources so that the screen 53 again obscures both beams, and the other drives a variable resistor 78 to regulate the speed of the conveyer motor 33. The invention may also be applied to other types of spinning machine.
