Abstract: 386,165. Radiators. VULLIERME, M., 84, Rue Michel Ange, Paris. March 19, 1932, No. 8242. Convention date, March 20, 1931. [Class 29.] For cooling the heat engine of a vehicle propelled by a screw propeller, cooling liquid is circulated in the interior of the propeller. Alternatively cooling fluid is passed through a radiator which in turn is cooled by a fluid circulating in the propeller. The boss of the screw propeller is provided with channels having ducts which coact with supply channels mounted in a casing on the propeller shaft. These supply ducts lead to tubes or passages proceeding along the length of the propeller blade and are introduced at different distances, from the propeller axes so that the differential centrifugal forces result in an outward flow from the passages 23, 24, through the conduits 9 .. 12 in the blades, and an inward flow to the passages 26, 27. The flow and return passages are connected to three cylindrical casings 14, 15, 16 concentric with the propeller shaft 1, these casings being connected to the engine cooling-water system. In a modification a fluid may also circulate in an annular surface channel forming the enlarged flared casing of the propeller boss. In order to provide a seal between the relative parts, diaphragm members and abutting flange members are fitted. In building up the propeller blade, transverse sections are assembled on a central tubular member 63, through which the outward flow occurs and the transverse members 66, 67 are perforated to provide the return portion 64 of the circuit. Where an auxiliary cooling fluid is circulated in the propeller in the direction 100, 101, the circuit of this fluid is completed by three pairs of sheet metal plates 94 .. 97 where it takes up heat from the main cooling water which enters between the pairs at 98 and leaves at 99.

Relates to elevating and training apparatus for a gun which is controlled by a sighting device such that when the sighting device is aligned with the target, the gun is automatically positioned in firing line with the target. The gun 17, Figs. 1, 3, is mounted on a rotatable carriage 16 carrying the gun trunnions 20 and casings 90 secured on the side walls of the carriage contain a series of fixed magnets arranged circumferentially of the trunnions and pairs of magnetic arms forming armatures 103 which are operatively connected to the trunnions and are rotatable in association with the magnets. A second series of circumferentially arranged magnets is supported in a casing 25 below the carriage and other pairs of magnetic arms forming armatures are connected to the bottom of the carriage and are influenced by the magnets for causing rotation of the carriage. Each magnet of each series is surrounded by a coil forming part of an electric circuit provided with a switch for each magnet such that certain of the magnets are energized to cause movement of the associated armatures and thus movement of the gun in elevation and/or training. The sighting device which, as shown, comprises a telescope 75 is carried by a horizontally rotatable bracket 76 by means of shafts 99 which permit movement of the telescope in a vertical plane. The switches for the magnets are arranged in casings 38, 91 on the sighting device in a manner similar to the arrangement of magnets, the arrangement being such that as the sighting device is moved to align itself on the target, switches are operated which energize correspondingly positioned magnets in each of the series so that the gun follows the movement of the sighting device. The switches are in the form of a commutator arrangement in which the commutator elements are connected to correspondingly positioned magnets and brushes directly connected with the sighting device move over the segments of the commutators.
