Title: Air intakes for gas turbine engines
IPC: B64D33/02
Filed: 1971-12-04
Abstract: 1382809 Gas turbine engines - air intakes ROLLS-ROYCE (1971) Ltd 28 Nov 1972 [4 Dec 1971] 56394/71 Heading FIG The invention relates to an air intake structure for a gas turbine engine in which the upstream lip of the intake comprises a series of U-shaped panel members 16a arranged circumferentially of the structure. Each panel member is mounted by means of a pair of rollers 24 in curved tracks 20 fixed to the structure whereby the panel members may be moved from a first position in which they form a bell-mouth for the inflowing air to a second position in which they form a larger bell-mouth for the inflowing air. The object of the invention is to prevent the adverse effect of cross-wind at the intake. Each panel member is movable by means of an air motor 30 and ball-screw mechanism 28 acting through a link 26 connected to the upstream end of the panel member. Each curved track 20 is of circular arc form, the centre of curvature (17) lying in the plane of the throat of the intake. The tracks 20 are mounted on V-section members (18) which are disposed between adjacent panel members 16a. Sealing members (36) are provided between adjacent members 16a so as to close the gaps therebetween.

Title: Laser generators
IPC: G02B27/00
Filed: 1972-12-07
Abstract: 1402438 Lenses COMMISSARIAT A L'ENERGIE ATOMIQUE 7 Dec 1972 [10 Dec 1971] 56617/72 Heading G2J [Also in Division H1] A laser is caused to oscillate in the single fundamental transverse mode by providing a divergent lens of homogenous absorbent material within the laser cavity. The absorbent lens 30, Fig. 8a, may be piano concave and is used in conjunction with a concave resonator mirror 2 to provide the equivalent of a plane mirror the focal point F of the lens and the centre of curvature C of the mirror being coincident. By forming the absorbent lens into a doublet with a normal plano convex lens 34, the mirror 2 is of a different radius of curvature or even be slightly convex if the refractive indices of the two lenses are different. If both refractive indices are the same a plane mirror 2 is required, Fig. 8b. Plane mirrors 2 are also used in the case of a triplet in which the absorbent lens 40 is biconcave. If the refractive indices are the same throughout the triplet the normal lenses 42, 44 are plano convex. If the refractive indices are different for the absorbent lens 40 and the normal lenses 46, 48, respectively, the latter lenses are biconvex. Magnification on a plane mirror surface is obtained in Fig. 8c by the combination of a biconcave absorbent lens 40 and a spaced normal biconvex lens 54. The mirror 2 may be combined with a doublet as shown in Fig. 9, and is provided as a coating on the combination of a biconcave absorbent lens 61 and a normal biconvex lens 62 of the same refractive index. Alternatively the mirror coating may be applied to a doublet formed of two plano concave lenses 58, 60. The laser is Q-switched by a Kerr or Pockels cell within the resonator, Fig. 5 (not shown), and may use an optically-pumped ruby, neodymium glass or dye cell as the active medium.

Abstract: In order to be able to sever safely the tensioned inner pipe 8 of, say, a disused well at a region within an outer pipe 6, the following procedure is adopted. First, access to the inner pipe is gained by severing it about a clamp 10 which holds the inner pipe 8 under tension, the inner pipe 8 is filled with filler material up to a chosen level 16, a charge of a particulate mixture capable of undergoing an aluminothermic reaction is inserted into the pipe 8 and the mixture ignited so that an aluminothermic reaction takes place which produces molten metal that penetrates through the pipe 8 and severs it. It is then safe for a person to enter the well and cut through the outer pipe 6 and inner pipe 8. The well can then be filled in and, if desired, the concrete basin broken up and removed. <IMAGE>
