Abstract: A development apparatus in which a plurality of differently colored particles are dispensed into a common sump. Differently colored particles are dispensed in a pre-selected ratio to form a resultant mixture of particles in the sump having a pre-selected color. This mixture is subsequently deposited on a latent image rendering the image visible in the pre-selected color.

Abstract: Techniques to render documents and like objects uncopyable by photocopy means. Illumination spectral composition, object background color, and photoreceptor sensitivity are appropriately combined such that the photoreceptor perceives no object contrast. The result may be either a blackout or a whiteout of the object information.

Abstract: The paper describes a series of measurements of contrast rendering factor (CRF) by two methods for a number of positions in ten different lighting installations. The ten targets used are representative of written and printed material found in offices. The results show that the major factors determining the value of CRF are the position of measurement and the specularity of the target material. The light distribution of the luminaires is relatively unimportant. These conclusions can be reached from measurements of CRF either as a ratio of relative visibilities or as a ratio of luminance contrasts.

Abstract: Safety-colors in hazardous areas are often essential for guidance and safety of personnel, and are often illuminated by commercial lamps Some commercial lamps fail to render safety-colors identifiably, and so confuse their message Rather than fault the light source, the safety-colors can be redesigned so that the burden of identifiability falls on them Redesign of spectral reflectance of safety-colors, and the addition of fluorescence, are both shown to allow the poorer rendering commercial lamps to render safety-colors more reliably

Abstract: The wall cladding, for an internal wall, has a decorative finish on the visible side, esp. in the form of a layer of plastic rendering, and is designed so that this can be easily removed when desired. The finishing rendering layer (3) is applied to a mackled-sheet wallpaper (2, 5, 6) which is at least two-layered. The layer of this with the rendering layer can be split off from the adjoining mackled-sheet layer. The wallpaper may have a splittable fibre structure.

Abstract: The identification of safety colors must not require other clues, but must depend on the identifiability of single colors. Experiments conducted by the IES Color Committee indicate that identification of these colors is questionable, if not impossible, under certain light sources. The author attempts to adapt the CIE Color Rendering Index to indicate those light sources that will not render the safety colors identifiable. In such cases, supplementary lighting can be specified to make the safety colors effective.

Abstract: The rendering of low contrast values by various mammographic imaging systems was investigated by a semi-objective procedure. Test exposures of a line raster with variable line widths were evaluated visually. Significantly better results were achieved by a xero-radiographic method. This was better than non-screen mammographic film in terms of object size, lower sensitivity to scatter and better resolution. The use of a tungsten rotating anode, with about 0.5 mm. Al filter, in xeromammography provided a satisfactory compromise between image quality and radiation dose in the rendering of low contrast studies.

Abstract: In an earlier study on textured polyethylene terephthalate (PET) yarn, the winding tension was varied by changing the overfeed in the winding zone from 2% to 8%, keeping all other texturing parameters constant. It was Observed that crimp gets progressively suppressed as the winding tension increases4.e. as the percentage overfeed decreases [2]. In parallel studies on nylon 66 Familant varied the overfeed between 0% to 670, and the results qualitatively show similar trend in the 2% to 6% overfeed range. However, there was a reversal a t low overfeeds or high tensions, and the crimp was found to be fully developed at 0% overfeed [I]. Thus for nylon 66 there appears to be a critical winding tension which results in maximum suppression of crimp. It has been suggested [l] that tensions above this level can result in stretching of the filaments and the potential energy due to this can release the latent crimp when the yarn is unwound. In fact, the mechanical-conditioning procedure, as described in the earlier publication [2], depends on this mechanism for release of crimp. The problem of latent crimp and its release by mechanical action or thermal treatment has been studied in considerable detail and will be reported elsewhere [3]. The results in our previous paper [2] covered overfeeds from 8 to 2%. The situation a t 0% overfeedi.e. under parity condition-has also been studied, and the complete data for a set of samples prepared at the same time are now presented in Figures 1 and 2. The sample preparation and other details are given in the earlier publication [Z]. It is immediately obvious that for PET also there is apparently a reversal point in the behavior of latent crimp with respect to overfeed or tension in the winding zone, and in this case, too, i t appears a t high tensions. However, it may be noted that the crimp in PET prepared at 0% overfeed is only marginally higher than that a t 2% overfeed, and the crimp is by no means fully developed. The tension developed in nylon 66 at 0% overfeed is 21.5 mN force (2.5 g f ) i . e . about 3.18 kJ/kg (0.036 gpd) [l], It has been noted (for example, see ref. [4]) that to open the crimp in PET, even 31.8 kJ/kg (0.36 gpd) is not sufficient. Moreover, the initial modulus of PET is higher than that of nylon 66. Though the tensions developed in the winding zone, 1 \"1
