IPC: F02M19/035
Filed: 1926-01-21
Abstract: 246,489. Pallas Apparate Ges. Jan. 22, 1925, [Convention date]. Spray carburettors. -The fuel nozzle extends transversely across the mixing chamber and is provided on opposite sides with fuel orifices discharging substantially at right-angles to the air stream, the nozzle being provided on the air inlet side with means to divert the airstream from the fuel orifices. As shown in Fig. 1, the nozzle a is provided on each side with a fuel orifice c discharging into a recess b cut in the nozzle. In a modification, an additional recess is provided on the air inlet side of each recess b, thus leaving a web or flange adjacent each orifice. In other modifications, a deflector, e.g. as shown at e, Fig. 4, is secured to the nozzle. The nozzle may be situated obliquely in the mixing-chamber, the edges of the recesses b or of the deflector being situated at right-angles to the air stream. The Specification as open to inspection under Sect. 91 (3) (a) describes also modifications in which the nozzle projects at right-angles half way across the air stream and is provided with an axial discharge orifice, the top of the nozzle being either cut off obliquely, or being provided with a projection on the air inlet side of the orifice. This subject-matter does not appear in the Specification as accepted.

Abstract: 265,945. Rosenberger, P. Feb. 15, 1926, [Convention date]. Casting-machines; moulds.-The mould of a casting-machine comprises one or more members movable within a shell to compress the casting and, if desired, sever the runner. The mouldmember 16, Fig. 3, can slide, against the action of a spring 17, in a half shell 7 which is mounted by means of fillets 6 on a support 4 adjustably fixed in guides 2, Fig. 2. The mould-member 18 is somewhat similarly mounted in a half shell 5 which is moved, to open and close the mould, by adjustable links 8, a crank-shaft 12 and handle 11. When the molten metal, poured through the gate 25, Fig. 3, has solidified, a slide 13, Fig. 2, is advanced by an adjustable link 15 and a treadle- or clutch-driven crank-shaft 14 to engage and move the member 16 to the right, thus severing the runner and, when the member 8 is arrested, compressing the casting. When the mould is opened, the casting, shown as a shaft bearing, is ejected by rods 22 and abutments 27, 23.

The tube in which the electrical image is formed and stored may be either of the image-orthicon type with independent means for controlling scanning with an electron beam of the target structure to produce picture signals; or of the storage-type image converter of Specification 836,229. As shown in Fig. 2, such a tube has a photo cathode 102; coaxial cylindrical electrodes 106, 107, 108, 109, electrodes 107, 108 having centrally apertured diaphragms 110, 111; a fine mesh collector electrode 105; a storage grid 104; and a fluorescent screen 103 carrying a metallic coating (not shown) which is electrically conductive and pervious to fast electrons. Typically potentials of 1, 2, 3, 3, 2-5, and 12 KV are applied to the parts 107, 108, 109, 105, 104, 103 respectively when the tube stores electric images on the grid 104 corresponding to those light images projected on to the photo-cathode 102. If the applied potentials are subsequently changed to 0À2, 0.45, 0.5, 0.5, 0 and 12 KV and the photocathode is uniformly illuminated by means of a light source not shown, the stored electrical image on grid 104 is converted into a bright picture on screen 103. In either case the picture produced may be photographed.
