Abstract: 1378742 Gusseted cartons BOXFOLDIA Ltd 7 Jan 1972 [8 Oct 1970] 47813/70 Heading B8P To prevent content loss and incursion of atmospheric environment, a carton is erected from a blank of laminated material partially cut through at the corner junction 17 of each closure wing 15 and flap 16 over at least a major portion of the length of the junction so that upon folding the flaps 16 over the wings 15 an inner lamina may delaminate at each corner from the remainder of the material to form an integral gusset 25. The area of delamination may be limited in part by a cut or score line (20, Fig. 2, 24, Fig. 5) in the inner lamina. The laminated material may be completely cut through over a minor portion of the length of the junction (22, Fig. 5). The flaps 16 may project beyond the wings (Figs. 3, 4). The inner lamina may extend part-way over the outer lamina of a flap 16 (Fig. 4) from the fold line 14 or beyond the flap, the excess outer or inner lamina being removed during carton manufacture. To facilitate delamination, adhesive employed for lamination may be less densely applied, may be partially or wholly removed, may be weaker or may be weakened by heat activation between the wing and flap laminae. Two different adhesives may be used to laminate the flap and wing laminae, one being softened prior to carton closure and one being cured at a higher temperature to cause rebonding. Inner and/or outer wing and flap laminae may be printed or impregnated with a release agent, e.g. oil or grease. Discrete or the whole area of the wings and flaps may be treated to facilitate delamination. The laminated material may comprise an outer lamina of wood pulp card adhered by wax or a thermoplastic resin to an inner lamina of glassine paper: part of the outer lamina may be removed to provide a window. The junction 17 may be offset from the corner fold 12.

Abstract: 1287612 Interferometer OFFICE NATIONAL D ETUDES ET DE RECHERCHES AEROSPATIALES 3 Oct 1969 [9 Oct 1968] 48747/69 Heading G2J [Also in Division G1] An interferometric device comprises first and second orthogonal reflecting surfaces 13, 18 and a beam-splitter surface 14, the latter and the first reflecting surface intersecting along a line 30 at 45 degrees and the plane in which second reflecting surface lies diverges at an acute angle from that plane which both contains the line of intersection 30 and extends orthogonally to the plane of the first reflecting surface. The reflecting surfaces may be part of transparent rectangular prismatic bars 10, 11 joined at their hypotenuse faces and having a layer of germanium therebetween acting as a beam-splitter and whereby in the first bar 10, the distance between the reflecting and the hypotenuse faces remains constant over the prism length but in the second prism 11 this distance increases resulting in an increased path difference for radiation incident on the beamsplitter. Radiation sweep along the device is achieved by displacement of the whole device with respect to the beam or vice versa by moving the beam across the beam-splitter. The intensity of the light efflux is measured photo-electrically in order to analyse the spectrum of the incident radiation. Alternatively, a collimator may be interposed in the path of the efflux and a Fourier transform of the radiation obtained. In a modification Fig. 22 the incident beam may have a large range of aperture angles and plates 60, 66 of materials of differing refraction co-efficients to the bars are utilized to give the appropriate path difference, alternatively the plates may be replaced by an enclosed air medium, the inside of further plates (84, 98) Fig.25 (not shown) acting as the reflecting surfaces. An interferometric apparatus incorporating the device is described, and the device may also be used to form fringes which may also be used to give spectral fringes.
