Title: Improvements in and relating to the forming of tubular or like members from impregnated fibrous material
IPC: B29C63/00
Filed: 1940-11-22
Abstract: 545,090. Tubular members of fibrous material. BOULTON PAUL AIRCRAFT, Ltd., and N ORTH, J. D. Nov. 22, 1940, No. 16827. [Class 99 (ii)] [Also in Groups V and XXXIII] Tubes or other hollow members, such as aircraft fuselages, planes and control surfaces are composed of an outer smooth shell 6 and an inner liner 4 having corrugations of flattened form, both composed of impregnated fibrous material, the structure being formed by compression under heat between a core 2 and an outer mould 1, with interposed wedges 3, 5 as shown. The core 2 may consist of an inflated bag, or a tapered core pressed axially may be used, the outer mould being then correspondingly tapered. The material consists of thin layers of wood, paper, fabric, felt &c. impregnated with a thermo-setting plastic material such as a phenol-formaldehyde condensation product, or with a thermo-plastic material such as a polyvinyl ester or co-polymer of vinyl esters. When made of fabric the shell 6 may be formed by winding a length of fabric. The heating may be effected by steam tubes or electrical heating-elements in or surrounding the mould, or by inflating the bag with hot gas. In aerofoils, the corrugations may become smaller towards the trailing edge, which is rounded sufficiently to permit of the continuation of the corrugations.

Title: Testing the uneveness of surfaces
IPC: G01B11/30
Filed: 1970-04-09
Abstract: 1312789 Testing surfaces NIPPON KOGAKU K K 9 April 1970 [10 April 1969] 16923/70 Heading G2J In a method of testing the uneveness of a surface of an article 1, the article is placed so that there is a wedge-shaped gap of angle # between the surface to be tested and a surface of a lighttransmissive article 2. A beam of coherent light 5, after passing through semi-reflecting surface H passes through the article 2 and is reflected from the surface of article 1, returning to surface H and being reflected to form a point image in the focal plane 4 of objective lens 3; multiple reflections between the surfaces forming the wedge-shaped gap cause a series of point images 6 to be so produced, the spacing of the images being 2f#, where f is the focal length of the lens 3. Reference beam 7 is reflected at surface H and at mirror 9 and combines with the beam 5 to produce a hologram on a photographic plate 10. The hologram is developed and returned to place and illuminated by beam 7, regenerating the point images b; the articles 1 and 2 are then rotated through an angle #, the angle # of the wedge being kept constant so that the mth point image produced by the beam 5 coincides with the nth regenerated image. The pattern of the resultant interference fringes indicates the variations of wedge thickness, variations of #/2(n-m) being detectable; if one surface is a reference surface of extreme flatness then this is a measure of the uneveness of the other surface. Alternatively the article 1 may be a reference surface which is replaced by the surface to be tested after forming the hologram. The surfaces do not need to be planar but may be curved. A half-wave plate (12), Fig.2 (not shown), may be provided in one beam, and a polariser (13) in the optical system for observing the fringes so that by rotating the polariser the visibility of the fringes may be improved.
