Title: Production of holograms
IPC: G03H1/04
Filed: 1972-01-26
Abstract: 1373011 Holography VICKERS Ltd 26 Jan 1972 [29 Jan 1971] 3545/71 Heading G2J Holograms are formed from a light beam which has passed through an object to provide diffracted and undiffracted rays, these sets of rays then being separated and caused to interfere to form the hologram. In one embodiment the undiffracted light rays passing object P-P' are focussed at a point 6 on a prism 5 whereas the light rays diffracted by the object are not so focussed. Both rays pass through a linear polarizer 4 before reaching the prism. The undiffracted light rays are reflected from point 6 by total reflection whereas the diffracted light rays are reflected from a metallic layer 7 (e.g. aluminium). The prism elliptically polarizes both rays which then pass #/4 plate 8 which linearly polarizes them but with different azimuthal angles. A Wollaston prism 9 has one of its vibration directions parallel to the direction of linear polarization of the diffracted rays. Consequently of the two output beams only one contains the diffracted rays whereas both contain undiffracted rays. The two beams are then brought into mutually parallel linear polarization by an analyzer 10 and then interfere to form hologram H-H'. If desired the prism 5 and #/4 plate 8 can be replaced by a polarizing film sandwiched between two glass plates and having an aperture through which the undiffracted rays pass. In a second embodiment the diffracted and undiffracted rays from object P-P' enter a conventional beam splitter 32. The undiffracted rays in one of the light paths are brought to a focus at a pin-hole aperture in a stop 35. In that path the stop blocks off the diffracted rays. The other path contains both diffracted and non- diffracted rays. Light from both paths is then caused to interfere to form the hologram H-H'. If desired the beam-splitter 32 and stop 35 can be replaced by a reflector having a small localized beam-splitting region at which the undiffracted rays are brought to a focus. The diffracted rays would not be incident on this region and so would be subjected to reflection only. The hologram may be formed from objects viewed in microscopes.

Title: Improvements in or relating to aircraft wings
IPC: B64C21/02
Filed: 1958-02-04
Abstract: 869,065. Aircraft. SEBAC NOUVELLE S.A. Feb. 4, 1958 [Feb. 7, 1957], No. 3657/58. Class 4. In an aircraft wing, compressed gas is conveyed through a spanwise extending passage to one or more devices employing discharge of the gas through ejector slots employing the Coanda effect to entrain ambient gas from the wing interior, and discharging into first and second collectors, gas being discharged from the first collector through a spanwise extending Coanda slot on the upper surface of the wing, and from the second collector through arcuate passages formed between the trailing edge of the wing and a rotatable control surface of substantially circular crosssection with a rearwardly projecting fin. The Figure is a cross-section of a wing, wherein a passage 1 extending spanwise is fed with compressed air from a source within the fuselage, and delivers at spanwise intervals into pairs of duct 2 (one pair shown) leading to pairs of manifolds 3 annular in plan, each joined by ducts 6 to an annular chamber 5. This chamber discharges through a slot 7, the issuing gas following the curve of surfaces 9 into collector members 11 feeding an annular chamber 12. The gas jet from slot 7 entrains air from the interior of the wing into chamber 12, and thus sucks ambient air through apertured areas, 18, 16, of the wing skin to remove the boundary layer. The width of slot 7 can be varied by relative movement of its walls. All the chambers 12 are connected by ducts 21 to a spanwise extending first collector 22 discharging through a slot 25, one wall of which is curved to induce the issuing gas to follow the upper surface of the wing. All the annular chambers 12 are connected by ducts 23 to a second collector 24 partially obturated by a flap comprising a cylindrical portion 31 and fin 32. Upper and lower arcuate slots 37, 371 are formed for the discharge of gas jets, these slots being divided at spanwise intervals by webs 39, 391 on the flap. The axis of rotation 41 of the flap is offset from the axis 33 of the cylindrical portion 31, so that the widths of the slots vary as the flap is deflected. The flap is formed with recesses at 40, 40<SP>1</SP>.

Abstract: 1,262,091. Papermaking. A. T. RANSON (BELOIT CORP.). 23 Jan., 1969 [24 Jan., 1968], No. 3724/68. Heading D2A. In a twin-wire papermaking machine, the upper and lower wires are led over first and second guides through paths that gradually converge in a forming zone where they are wrapped around the upper down-running quadrant of the second guide and then become generally parallel and remain so over a third guide. A large-diameter rotatable roll forms the second guide or part of it, and the first and third guides serve to tension the top belt over it without any restraining means in contact with the belt opposite the forming zone. The slice is arranged to deliver a stream of stock to the convergent zone, preferably in a direction aligned with the first part of that zone. As shown, the wire 53 passes round a first guide roll 54 and the wire 11 over a stationary shoe 71, so that they converge and then pass on to the roll 52 and then over a suction roll 55. The roll 52 may be foraminous or solid. Stock is supplied by the headbox 58 and is dewatered through the upper wire in the zone F5, by the combined effect of the hydraulic head h and centrifugal force 53b and 11b are skimming devices cooperating with the save-alls 53c and 52b. In another embodiment (Fig. 2, not shown), the shoe 71 is omitted, and the wires and stock pass directly to a large roll 42, similar to the roll 52 shown. A series of devices of either kind can be arranged with a common lower wire to form a multiply sheet (Figs. 1 and 4, not shown).
