Title: Improvements in or relating to dichroic images and to a method of forming same
IPC: G03C9/04
Filed: 1944-05-30
Abstract: 619,941. Dichroic images. INTERNATIONAL POLAROID CORPORATION. May 30, 1944, No. 10395. Convention date, Sept. 22, 1943. [Classes 97 (i) and 98 (ii)] A dichroic image is produced from a photographic print by converting the silver image into a complex containing releasable iodine by treatment with a solution containing cupric, ammonium and iodide ions and pressing the treated print against a molecularly oriented sheet of light-transmitting polyvinyl oxy compound, preferably polyvinyl alcohol, whereby the iodine is transferred to the sheet. The print is first treated with a solution containing ammonium iodide, ammonium chloride, sodium hydroxide and cupric chloride, whereby the silver image becomes slate-blue in colour and apparently becomes silver iodide combined with a complex compound, probably tetramine cupric iodide. Alternatively, the silver may first be converted to a non-soluble salt by suitable toning and then treated with the above solution. The print is then washed in water or in a dilute solution of the treating liquid and is then treated with a solution of nitric acid and cupric chloride, whereby free iodine is released and the image becomes orange-brown. The treated print is then pressed as by rollers against the polyvinyl sheet when the iodine is transferred thereto in amounts corresponding to the density of the original silver image. The print may then be treated with a suitable developer, restored to its original condition, and the process repeated. In alternatives, cupric sulphate may be used, and the nitric acid may be replaced by hydrochloric or sul. phuric acids or by hydrogen peroxide. Instead of forming a separate bath, the acid may be incorporated in the polyvinyl sheet. For preparing stereoscopic images, two prints 40, 50, Fig. 6, corresponding to left- and right-eye views are treated as described above and are pressed against opposite sides of a polyvinyl sheet 60, the molecules on one side of which are oriented at right angles to those on the other side. This may be achieved by laminating two such sheets together, or to a central layer, or alternatively a single sheet with different surface orientations may be employed. The iodine images are transferred by the aid of rollers 65, care being taken to ensure that the images 70, 75 are in correct registration. When the print is viewed through polarizing glasses having their transmission axes respectively parallel to one or other of the transmission axes of the images 70 and 75, each eye will see only one of the images.

Title: Improvements in stator windings for alternating current dynamo-electric machines
IPC: H02K3/12
Filed: 1928-04-05
Abstract: 299,694. Ateliers de Constructions Electriques de Charleroi. Oct. 29, 1927, [Convention date]. Coils and conductors. - The laminated stator conductors of an alternating-current dynamoelectric machine are connected by evolute end connectors in such a way that the individual laminations of one conductor are connected in inverse relation to laminations of a second conductor as shown in Fig. 4. The electromotive forces induced by the flux across the slots are thus compensated in a group of two conductors. In the case of machines having two conductors per slot, as shown in Fig. 3, the end connectors at each end are arranged in four planes and the following three conditions hold. (1) the ends of the conductor are in four planes and the connectors A, B joining the pairs of conductors 1, 3 and 2, 4 are turned in opposite directions, (2) a conductor at the top or bottom of a slot is connected to a conductor similarly placed in the second slot, and (3) a conductor in a slot containing two conductors of the same phase is connected to a conductor in a second slot also containing two conductors of the same phase and a conductor in a slot containing conductors of different phases is connected to a conductor in another slot containing conductors of different phases and identically similar as regards dispersion flux. At the end A, B of the core the individual laminations of a conductor are folded on their flat sides and soldered separately to the laminations of the second conductor, and the laminations are insulated from each other by mica sheets except at the opposite end of the core where they are soldered to evolutes and connectors of solid copper. The electromotive forces induced by the transverse flux may be compensated by connecting in series any even number of conductors, but in this case laminated end connectors must be employed at both ends of the core. The invention is also applicable in cases where more than two conductors are situated in each slot. Specification 133,961 is referred to.
