Title: Method and device for producing three-dimensional images
IPC: G03B35/24
Filed: 1969-06-10
Abstract: 1276017 Optical apparatus; photographic apparatus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 June 1969 [10 June 1968] 29277/69 Headings G2A and G2J [Also in Division H5] A three-dimensional image of an object is obtained by forming a holocoder (defined) with non-coherent radiation and then converting the holocoder into a visible image. The holocoder may be a single strip or a composite comprising a plurality of identical strips, the length of the or each strip being considerably greater than its width, each strip corresponding to a given viewing angle of the object. The or each holocoder strip is made by exposing a photographic film to incoherent radiation from the object by means of lenses arranged in a row parallel to the plane of the film and at right angles to the direction of the length of the film. The three-dimensional image is formed by imaging the holocoder strip or strips by a row of lenses parallel to the plane of the holocoder and to the direction of the length of the strip or strips. The incoherent radiation may be white light, X-radiation, or the scanning light beam from a cathode-ray tube. In one embodiment a hologram is made comprising a single or plurality of strips. A holocoder strip 33, Fig. 5, is illuminated with diffused coherent radiation, light from the strip then passing a row of lenses 34 whose orientation relative to the strip corresponds with that when the strip 33 was formed. The lenses form an image on film 30 where interference occurs with reference beam 38 to form a hologram or strip hologram. If desired a lens 36 may be put between lenses 34 and film 30, these latter being in the respective focal planes of lens 36. The three dimensional images maybe reconstructed from the holocoder strip(s) to give an image the whole of which is visible to the observer by having a lens 56, Fig.7, or mirror 57 which is oscillated in the direction of the strip(s) width. Alternatively an oscillatable semi-transparent mirror and a concave mirror may be used; or a semi-transparent mirror and an auto-collimating screen. Where the radiation used is X-radiation the strip holocoder is a series of shadow graphs in a common plane but taken at different angles, the shadowgraph pictures then being assembled and, if necessary, reduced to form the linear strip holocoder.

Title: Improvements in elastic fabric and elastic yarns for use therein
IPC: D03D15/56
Filed: 1948-11-11
Abstract: 678,507. Elastic yarns. CLAY, P. E. F. Oct. 13, 1949 [Nov. 11, 1948], No. 29297/48. Class 120(iii) [Also in Group VIII] A method of making elastic yarn comprises stretching an elastic thread to a predetermined extent, retaining it in a stretched condition and while so stretched applying thereto at least one close-pitched helical wrapping of a relatively inextensible thread, such as a textile thread, and applying to the elastic yarn thereby produced at least one further wide-pitched wrapping of a relatively inextensible thread to inhibit further stretch, said inextensible thread of the wide-pitched wrapping being removable or destructible, as for instance by chemical means that is harmless to the elastic thread and closepitched wrapping. As shown the elastic core thread 10 is held stretched a predetermined degree and has applied thereto a closely pitched, clockwise helical wrapping 11 of a relatively inextensible thread, e.g. cotton and a similar superimposed counter-clockwise wrapping 12. Over this outer helical wrapping is applied two further wide-pitched helical wrappings 13 and 14 of relatively inextensible thread, respectively, clockwise and counter-clockwise. The wrapping threads may be applied by apparatus similar to that described in Specification 517,978 and the yarn when formed may be used in the manufacture of elastic fabrics in any desired manner, e.g. by using them as weft threads in a knitted warp fabric. The stretch inhibiting threads 13 and 14 may be of alginate or wool and are essentally of a material different from that of which the fabric is made and are of such a nature that they can be destroyed as by chemical means. Specification 520,640 also is referred to.

Title: Improvements in and relating to multicell structures
IPC: H01Q15/08
Filed: 1952-11-20
Abstract: 738,175. Making multi-cell structures. GENERAL ELECTRIC CO. Nov. 20, 1952 [Nov. 23, 1951], No. 29342/52. Classes 83 (2) and 83 (4). Destructible cores.-A method of making a multi-cell structure comprises winding a corrugated metal strip along with a flat metal strip to form a roll having a plurality of cells in parallel axial alignment, deforming the roll to give to it a concave configuration on one side and a convex configuration on the other side, sintering the roll to fix it in the concaveconvex position, filling the cells with a liquid, solidifying the liquid and then forcing the roll to flat-ended configuration whereby the axes of the cells are brought to an axial or common focus. A metal strip 10 is corrugated by being passed between gears 11 and is then wound together with a flat metal strip 12 into a roll to form a plurality of cells. The loosely assembled multi-cell 13 is placed upon a convex former the degree of convexity depending upon the focal length which is desired in the final multi-cell and the multi-cell is given a concave-convex conformation. The multi-cell is now placed on a former 14 in a furnace 15 and sintered to fix the cells in position. The heating temperature for steel strips is approximately 1200‹ C. After heating the multi-cell is cooled and immersed in a liquid, e.g. water, which fills the cells and the liquid is then frozen in a freezer chest maintained at approximately - 20‹ C. The icefilled multi-cell is placed between flat plates 20, 21 in an arbour press and slowly pressed to restore the initial flat configuration and this pressing re-aligns the axes of the individual cells so that they are inclined towards a common focal point as shown in Fig. 7. The strips may be of nickel or aluminium approximately 0.001 inch in thickness. Multi-cells of soft metal, e.g. pure lead or cadmium, may be fabricated by folding a foil of the soft metal on either side of a thin foil of steel or aluminium which acts as a support.
