Abstract: 297,773. Soc. Franþaise de Cinematographie et de Photographie Films en Couleurs Keller-Dorian. Sept. 27, 1927, [Convention date]. Colour photography. - Enlarged or reduced copies of colour-record images made on lenticular films are produced by optical projection by first copying the images on to an intermediate ordinary film not provided with lenticular elements, and then copying the images of the intermediate film on to a lenticular film. The projection system comprises two objectives o, o<1>, having a focal ratio equal to the magnification required, with a diaphragm D at their common anterior focus. f is the original image in the first step of the process, and f<1> the ordinary film. The individual colourrecords are reproduced in successive picture-areas on the film f<1> by employing diaphragms D corresponding to the colour areas of the filter used in taking the original film. To reproduce the intermediate film, the same projection system and method of procedure is employed, but the colour-records are reproduced in juxtaposition in the same picture-area. If the original film is a negative, the intermediate image will be positive, and the final film will be developed and reversed to produce a positive. The reversal step may be employed in producing any of the three films.

Abstract: 666,381. Electric welding. SOC. MAROCAINE TECHNIQUE ET COMMERCIALE. Nov. 26, 1949 [Nov. 30, 1948], No. 30368/49. Class 83 (iv). In an electrical apparatus for wolding together the edges of sheet metal work-pieces, an alternating magnetic field, produced by an inductor, passes perpendicularly from one edge to the other edge of the work-piece so that eddy currents separately arise in the two edge regions which after reaching a suitable temperature are bonded together by pressure. The edges of a magnetic work-piece 3 are heated by the eddy currents and hysteresis loss caused by a magnetic flux passing from the pole tips 1<SP>1</SP>-1<SP>1</SP> of a laminated magnet 1 energized by a heavy alternating current of musical frequency passing through a hollow copper conductor 4 from a secondary winding 13, 13<SP>1</SP> of a transformer and hollow conductors 5, 5<SP>1</SP>, 6, 61, 7 and 71; the flux passes across gap 2 perpendicular to the edge faces of the work-piece 3. On reaching welding temperature the edges are pressed together by rollers 10 which also draw the work-piece 3 along beneath magnet 1. Cooling water, entering at 9 and leaving at 91 is circulated through the hollow conductors 4, 5, 5<SP>1</SP>, 6, 6<SP>1</SP>, 7 and 71. Conductors 6, 61, 7 and 71 secured to an insulated block 15 hold the iron sheets, forming magnet 1, in position. More than one conductor 4, which may be independent of, or as shown, attached to conductors 5, 51, may be used if it is desired to eliminate the transformer. The polepiece 1<SP>1</SP>-1<SP>1</SP> are shaped to the circular form of the workpiece and have a cross-section which decreases as it approaches the work-piece. Rollers 10 may be insulated to prevent magnet leakage. The heat caused by eddy currerits may be used for the welding of non-magnetic materials.
