Title: A method and device for the simultaneous interferometric measurement of a plurality of dimensions
Inventor: MOTTIER FRANCOIS
IPC: G01B9/02
Filed: 1969-01-23
Abstract: 1,214,124. Interferometers. BROWN, BOVERI & CO. Ltd. Jan.23, 1969 [Jan.25, 1968], No.3856/69. Heading G2J. A plurality of dimensions are measured simultaneously and interferometrically by dividing a mono-chromatic beam 16 into a reference beam 19 and an outgoing measuring beam 18 which traverses an "x" dimension to be measured, the beam 18 being further divided at a fuse 11 of a prism 9 into a partial beam 20 and a partial beam 24 which after a further reflection at fuse 22 of prism 9 traverses a "y" dimension to be measured, the partial beam 24 being returned via a prism 14 to the prism 9 where it re-combines with the partial beam 20 to form a returning measuring beam 26 which in turn re-combines with the reference beam 27 returning from a prism 6 at the original beam divider 5 to form a light beam 28 which is differently intensity-modulated over two partial crosssections, the intensities being detected at 7. The splitter face 11 of prism 9 has two prisms 12, 13 on non-adjacent quadrants thereof, the partial beam 20 exiting through prism 13 and returning through prism 12. The assembly of prisms 9 and corner prism 10, and prism 14 are movable in the "x" dimension relative to the first beam-splitter 5, and prism 14 is movable in the "y" dimension relative to prism 9. The sum of the cross-sections of partial beams 20, 24 is equal to the cross-section of beam 26. That part of the final beam 28 corresponding to partial beam 20 is intensity modulated according to the "x' dimension and that part corresponding to partial beam 24 according to the "(x+y)" dimension. The phase of the modulation is detected by forming a wedge-shaped coating on the interface of beam divider 5 and prism 6. If a third dimension is to be measured the partial beam 24 would be further subdivided into third and fourth partial beams one of which would traverse the third dimension.

IPC: B64C25/34
Filed: 1959-02-05
Abstract: 911,121. Retractable undercarriages. ENGLISH ELECTRIC CO. Ltd. Jan. 29, 1960 [Feb. 5, 1959], No. 4170/59. Class 4. In an aircraft main undercarriage co-operating with a conventional nose wheel, the main wheels 1 are journalled in tandem arrangement in two closely spaced groups on the end of a beam 3 pivoted at one end to one end of a shockabsorber strut 4 slidable in a frame 5 which is rotatable about a transverse pivot axis 6 on the aircraft structure and on which a two-armed lever 10 is pivoted, one arm of lever 10 being articulated to the upper end of shock-absorber strut 4 and its other arm through another shockabsorber strut 12 to beam 3, the upper end of shock-absorber strut 4 being also linked to the aircraft by a radius rod 8. Frame 5, suspended on the centre line of the fuselage by a pivot 6, carries strut 4 pivotally attached by a pin 9 to one end of lever 10 and to the lower end of rod 8 mounted on the airframe by a fixed pivot 7. Lever 10, mounted on frame 5 by a pivot 11, is attached at its other end by a pivot pin 13 to one end of a shock absorber strut 12, the other end of which is attached by a pivot pin 14 to the beam 3, on which the wheels 1 are journalled by transverse axles 2 and 34. The axle 2 is fixedly mounted on the lower end of the strut 4 and permits pivotal movement of the beam 3 in a vertical plane. Frame 5 is also pivoted to a connecting rod 44, which is pivoted to the strut 16, itself rotatable about the joint 17 by operation of the jack 18. To provide lateral stability the frame 5 carries a pair of struts 22, 23 each arranged as a parallel linkage to support a bracket 26 on which is journalled an outrigger wheel 28, a shock absorber 30 being provided between frame 5 and each strut 22. To retract the undercarriage, the jack 18 is contracted, thereby folding connecting rod 44 and strut 16 about the joint 15 and rotating frame 5 about axle 6. This action causes strut 8 to swing the lever 10 about axle 11, and strut 12 will thereby turn the beam 3 into the position, Fig. 2 (not shown), in which the centres of the axles 2, 6 and 34 lie substantially in a straight line. Also, when the frame 5 is retracted, the shock absorber struts 30 cause the struts 22 to swing inwardly against stops 33, mounted on the frame 5. This position is reached when the line X-X has rotated to the position X 1 -X 1 . The strut 30 is then compressed upon further retraction of the frame 5 to its fully retracted position, Fig. 2 (not shown).

Abstract: 438,590. Twisting artificial silk ; woven fabrics. DREYFUS, H., 22, Hanover Square, London.-(Celanese Corporation of America, (partly) ; 180, Madison Avenue, New York, U.S.A.) Feb. 9, 1934, Nos. 4303 and 19875. [Classes 120 (ii), 120 (iii), and 142 (iv)] Cellulose acetate threads are twisted to a high degree in at least two stages, and during at least the final stage of twisting the threads are steamed under conditions such that moisture is present. The steam may be at atmospheric or elevated pressure. The tension on the threads during twisting in the presence of moist steam may be sufficient to effect a considerable elongation with reduction in denier. The threads may consist of continuous or discontinuous filaments which may contain pigments or loading materials. Twisting may be effected by drawing the thread over the end of a rotating package through a guide fixed in line with the axis of rotation, and passing it on its way to a winding bobbin, through steam. The steaming device is arranged so that twisting takes place while the thread is under the influence of steam. Flyers or floating ring devices for restricting the ballooning of the thread may be used The steaming device may be a chamber situated vertically above one or more twisting spindles and provided with inlet and outlet holes for the threads. It may take the form of a horizontal pipe. The presence of moisture may be ensured by the use of wet steam or by arranging for condensation. A free escape of steam on to the thread as it is drawn from the spindle may be effected. A shield or funnel may be fitted round the thread approaching the steaming device. The threads may be moistened with water before twisting or just before entering the steaming device. The threads produced are smooth and cylindrical. The amount of twist may be such that the apparent specific gravity of the thread is more than 85 per cent of the actual specific gravity of the component filaments. The threads may be sized with casein, egg-albumen, linseed oil, or other substance at any stage of the manufacture. The threads may be associated, in the production of fabrics, with low or high twist threads of cellulose acetate, regenerated cellulose, natural silk, or other material. In the weft, pairs of crÛpe threads of left-hand twist may alternate with pairs of right-hand twist crepe threads, and the warp may contain low twist threads. The fabrics may be subjected to hot aqueous treatment in order to obtain crepe effects. Specifications 304,806, [Class 120 (ii)], 348,589, 424,683, 424,752, 424,830, and 424,879 are referred to.
