Abstract: 320,147. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 13, 1928. Retort furnaces.-In the heat treatment of solid materials, these slide down through heated pipes or retorts mounted at such an angle that the charge moves freely, baffles being provided to prevent the material from filling the retorts. The charge runs from a bunker 13 into charging ,hoppers 14, the rate of charging being controlled by the amount drawn off at the outlet 15, and the material passes in zig-zag fashion through the retorts 2 the thickness of the layer of material being controlled by baffles 20, the intake passages 4 and the retort intake 28. The retorts are heated by burners 11, the hot gases from a combustion chamber 5 being mixed in a chamber 7 with combustion products drawn by a blower 10 through a conduit 9.

Abstract: 299,299. Fabrik Explosionssicherer Gefõsse Salzkotten Ges. Oct. 22, 1927, [Convention date]. Fixed-chamber apparatus, controlling passage of air for.-In apparatus for delivering measured quantities of liquid of the kind provided with a vent pipe, the mouth of the pipe is provided with a throttling-device which is normally open, but is actuated automatically by the liquid to reduce the vent passage when the filling is nearly completed. The vent pipe 7, Fig. 2, extends into the dome 1 of the measuring vessel and is provided with a flange 9 forming a seat for a plate 10 carrying a valve 13 normally held open by a light spring 15. As the vessel fills, the air escapes freely through holes 11, 12 in the plate 10, but when the liquid rises above the top of the pipe 7 it actuates the valve 13 and closes the hole 11. As the vessel empties, the valve is lifted by the spring and the plate 10 is also raised from its seat by the inflowing air. In a modification, the plate 7 is provided with a cap 16, Fig. 3, provided with a plurality of holes 17 all but one of which are closed by a float 20 when the vessel is full.

Title: Improvements in aeroplane launching devices or catapults
IPC: B64F1/06
Filed: 1924-09-01
Abstract: 239,044. JeansÚn, C. F., and Stone, E. F. Sept. 1, 1924. Launching-ways.-Aeroplanes are launched from a carriage adapted to be impelled along a track by the force derived from the expanding gases of an explosive such as smokeless powder. The aeroplane rests on a carriage 1 adapted to be drawn along rails 3 by a cable 13 which is passed over the guide pulleys 14, 15 and backwards and forwards over multiple pulleys 17, 18 and is secured to lug 16 on a cross-head 8 carrying the pulleys 17. The cross-head 8, sliding on rods 9, is connected to a piston moving in a cylinder 6, one end of which is in communication with one end of a chamber 21 having an explosion chamber 20 at its other end for the reception and firing of appropriate cartridges. As the piston nears the end of its stroke is uncovers ports leading to exhaust chimneys 24. Buffers 12, 25 cushion respectively the cross-head 8 and carriage 1 at the end of their travel. The cable 13 is initially tensioned, and the carriage 1 released when a predetermined pressure in the chamber 21 is exceeded, bv a device shown enlarged in Fig. 7. The carriage is connected to a drawbar 28 by a pivoted catch 30 held in its closed position by a dog 34 on a trip lever 35 which is engaged by a surface 137 on a member adjustably connected to a frame 26. The frame has lugs 27 sliding on the rails 3 and is adjusted in position and anchored by a screwed shaft 45. The drawbar 28 is resiliently .held in its normal position by springs 43, 44, and upon a predetermined outward displacement of the drawbar the catch 30 is released. A modification is described in which the expansion chamber 21 surrounds one end of the cylinder 6, and the piston-rod connected to the crosshead is drawn in instead of being pushed out of the cylinder. The valve is moved over ports 49 by a non-rotary screwed stem 51 engaged by a drum 53 turned by a cord 56 attached at 58 to the crosshead 8. The ports 49 are partially open initially and the opening is increased as the crosshead moves outwards. Passages 59 transmit the cylinder pressure to the ends of the valve chamber.
