[Also in Group XL (b)] In a colour-photographic or colour television (see Group XL (b)) process a selected colour (other than white), e.g. human flesh tones, is recorded with at least two component colours (preferably red and green) of equal intensity. This reduces distortion of the selected colour when non-linear steps occur in the process. Fig. 7 shows one embodiment of the colour-photographic aspect of the invention and comprises a three-layer subtractive colour film transparency, the support 104 of which carries colour filter layers 101, 102, 103 related to the conventional primary colours. To carry out the present invention with this (conventional) film an additional filter layer 105 having the preselected colour is also applied to the film or the film support 104 may itself be tinted in this colour (Fig. 8, not shown). If reproduction is to be effected by a print on an opaque support the colour filter layers and the filter in the selected colour are carried by an opaque white support (Fig. 9, not shown). The invention may be employed in both additive and subtractive processes and in processes where the colours to be reproduced are composed of more than three components, e.g. in printing processes which employ a " blackprinter."

Abstract: 533,252. Making hollow glassware. UNITED GLASS BOTTLE MANUFACTURES, Ltd., and DORMAN, E. P. Oct. 23, 1939, No. 28487. [Class 56] A method of making thin hollow glassware, particularly tumblers, consists in depositing a charge of molten glass on a table or other surface, flattening the charge to form it into a disc-like parison and then, while supporting the parison at its edges, pressing or stretching the central portion to form a cup-shaped article. Apparatus for carrying out the method may comprise a table A, Fig. 1, which is movable in a vertical direction, a plunger D that co-operates with the table, and a mould ring B which also co-operates with the table A and is so mounted that it can be swung horizontally between the table A and a die member C below a plunger F. The ring B and the die C each may be made in two parts hinged together. The plunger F has an enlarged head F<SP>1</SP> which supports a sleeve G rotatably mounted on the stem of the plunger. A bottom plate H, for moulding the lower ends of the ware, is disposed below the plunger F. In use, a charge of glass E<SP>1</SP> is deposited on the table A within the mould ring B, and is flattened by the plunger D. The table A is then lowered, and the parison, which is supported at its periphery by the ring B, is carried horizontally by the ring into position above the die C. The plunger F then descends and stretches the central part of the parison into a cup-like form, as shown in Fig. 4, the bottom being shaped by pressure against the plate H. During the movement, the sleeve G is rotated continuously to shape the interior of the glass cup, the sleeve having been wetted previously, by a water spray J for example, to enable it to revolve freely within the glass. Finally, the plunger rises, the members B and C are opened and the cup is removed for further treatment.
