Abstract: 1,73,001. Photographic distortion. REYNOLDS METAL CO. Aug. 14, 1964, No.33279/64. Heading G2C. A design to be printed on to a flat sheet which is then to be drawn into a curved shape such as a cylindrical container is printed in a distorted fashion, such that the drawing operation "undistorts" the design back to its original form. Fig. 1 (not shown) is the design in its original rectangular form, and as it is intended to appear on the curved side of the finished container after shaping. To accomplish suitable distortion, the design is first photographed through a cylindrical lens Fig.2 (not shown), which elongates the design in the vertical direction only (dimension c), the horizontal dimensions remaining unchanged. The photographic negative now produced is wrapped round a glass cylinder placed at the centre of a conical mirror Fig. 4 (not shown), and a further photograph taken of the reflection of the photographic image in the conical mirror, which will now be distorted into an annular shape as shown in Fig. 5. This image is then printed on to a flat sheet 70 of metal stock which is to be drawn or pressed to form a cylindrical container with one end closed. The sheet 70 is cut to a circle just larger than the outer periphery A" of the design, and then pressed into shape by the press of Fig. 6 (not shown). The distortion of the design caused by this operation is in the opposite sense to the distortion by the photographic process described above, so that the design is restored to its original form, now carried by the cylindrical surface of the container. Various different frusto-conical mirrors may be used in the photographic step of Fig. 4 (not shown) for obtaining different results, and in some cases the first step of photographing through the cylindrical lens Fig.2, (not shown) may be omitted.

Mixtures of organic compounds are separated by gas chromatography, the temperature and pressure of the carrier gas both being above those defined by the critical point of the carrier gas. Particularly suitable carrier gates (such as ethylene, ethane, and carbon dioxide) have critical temperatures of -100 to +300‹C., but most preferably of about room temperature, and the temperature of the carrier gas is desirably, maintained up to 100‹C., preferably up to 50‹C., above its critical temperature.The stationary phase may be a solid or a liquid on an inert support. The solids used in the examples are Al 2 O 3  and commercial adsorbent. consisting principally of SiO 2  and also containing Al 2 O 3 , Fe 2 O 3  and CaO, but high molecular weight polymers and ion exchange resins may also be used. Where the carrier gas is non-polar, preferred liquid stationary phases are those which are associated by strong hydrogen bonds, such as water, glycerol, diols, and polyglycols. Very high molecular weight organic liquids which are not taken up appreciably by the supercritical carrier gas may also be used. The apparatus illustrated in the Fig. (not shown) includes a carrier gas supply (8), injection device (3) and (9), jacketed column (1) containing adsorbent, and pressure reducer (6). Spacer (7) is jacketed to compensate for the adiabatic cooling of the carrier gas on expansion. Gas escapes through delivery tube (10) into vessel (11), where separated products accumulate in liquid form in elongated section (13). Using this apparatus, sharp separations of (a) n-hexadecane, n-octadecane and n-octadecene-1, and (b) 2-ethyl hexanol and benzyl alcohol are described, using supercritical ethylene at 20‹C and 100 atoms, as carrier gas for the separation.
