    • 220,746. Hardy, A., and Johnson, L. K. June 12, 1923. Cameras, roll-film, masking in; roller-slides. -In a camera adapted to take spools of difterent widths, the spools are mounted on holders comprising end plates 15, 16, Fig. 7, with the centering pins and telescopic arms 17, 18, which are connected by a retracting spring 21. The spool housings, Fig. 1 and 5, have a series of slots 33, corresponding to different widths of films into which the peripheral sections 31 of the discs 15, 16 fit and the spool-holders are held in position by the projections 32 against which the back cover 2 abuts. For the winding- on spool the turning disc 24 and an inner disc 25, Fig. 5, carrying the stud 28 for the, winding end of the spool are screwed together and shaped to form a peripheral groove 27 engaging a stamped-out edge of an opening in the plate 15. The recesses 29, 30 are engaged by the end 49 of a retractable winding stem 45. This stem rotates with the sleeve 39 and can telescope within it against the action of the spring 47 and the sleeve 39 itself can telescope a limited extent within an outer casing 36 against the action of the spring 40 so as to allow the forked head 49 to come within the side panel of the camera when the largest spool is used. The casing 36 is mounted between an outer bracket 38 and an inner flanged plate 37 which is flush with the inner face of the camera, and this casing 36 is turned by the winding handle 44 and cross-bar 41. To prevent the winding handle being turned backwards, spring-positioned rollers 52 are interposed between the retaining flanges of the plate 37 and inclined cam faces 53 carried by the casing 36. A series of nesting masks 55 is provided within the camera frame, the inner mask being of a size corresponding to the film used, and the film is pressed on to the rear face of the masks by a pressure plate 56 with flat springs 57 contacting with the outer cover 2. Inclined inspection slots 58 in the cover 2 and plate 56 are provided to allow inspection of the numbers on the different sizes of films.

    • One of first and second beams (28) of corresponding first and second light (13) are projected into an atmosphere (20) and at least one physical property of the atmosphere (20) is detected from the interference pattern (47) generated from the resulting scattered light (30). The first and second beams (20) are selected responsive to either a detected signal-to-noise ratio (SNR) or a detected aerosol-to-molecular ratio (AMR). The wavelength (740) of the first light (13) provides for either molecular or aerosol scattering, whereas the wavelength (738) of the second light (13) provides for primarily only aerosol scattering. In accordance with a second aspect, scattered light (30) from one or more beams (28) of substantially monochromatic light (13) projected into the atmosphere (20) and received from a plurality of interaction regions (17) or measurement volumes (52) provides for determining wind power (P*) within a region of the atmosphere (20).
    • 对应的第一和第二光(13)的第一和第二光束(28)中的一个被投射到大气(20)中,并且从由所述大气(20)产生的干涉图案(47)检测大气(20)的至少一个物理特性 造成散射光(30)。 响应于检测到的信噪比(SNR)或检测到的气溶胶 - 分子比(AMR)来选择第一和第二波束(20)。 第一光(13)的波长(740)提供分子或气溶胶散射,而第二光(13)的波长(738)主要仅提供气溶胶散射。 根据第二方面,从投影到大气(20)中并从多个相互作用区域(17)或测量体积(52)中接收的基本单色光(13)的一个或多个光束(28)的散射光(30) )用于确定大气区域(20)内的风力(P *)。
