Abstract: 668,295. Spray carburetters; regulating; vaporizers. CARTER CARBURETOR CORPORATION. Jan. 31, 1949, No. 2580/49. Classes 7(ii), 7(iii) and 7(vi), Spring loaded valves 83, 84 in intake manifold passages 16. 17 with ports 89, 89a controlling the intake manifold branches 18. 19, 22. 23 are urged open solely by the mixture flow below a predetermined engine speed, above which they are completely opened by a suction-actuated device 109. A double-barrel carburetter 31 with mixture outlets 32, 33, feeds the two passages 16, 17 in a manifold riser 15 leading respectively to the branches 18 19 and 22, 23, each of which feeds two cylinders. The valves 83, 84 comprise ported cylinders sliding in the-passages 16, 17 and connected by links 94, 94a, to levers 97, 97a fixed to spindles 98, 98a carrying arms 101, 101a on which act valve-closing springs 102, 102a anchored at the opposite ends of a balance bar 104 pivoted on a knife edge 106 so that as one valve opens the tension of the loading spring of the other valve is increased. The arms 101, 101a are provided with extensions 121, co-operating with a bar 117 freely pivoted at 98, 98a and actuated by the suction device 109. During cranking the valves 83, 84 are first opened by suction to expose small ports 92 and fuel from the idling jets 64 collects in the valve-bottoms 88, 88a and is then blown as jets directed down the respective manifold  branches through the ports 92. The valves then open farther to expose parts of the ports 89, 89a and the mixture drawn therethrough provides good atomisation of the fuel. As the engine speed rises, the valves are drawn down to increase the opening of the ports 89, 89a. Above a predetermined speed the suction in the Venturi 50, transmitted to the device 109 through a pipe 122, becomes sufficient to actuate the piston 113, whereby the bar 117 is raised to contact the lugs 121, and forces the valves 83, 84 completely open. Shallow depressions 99, Fig. 4, accommodate the flanged ends 88, 88a, of the valves in the full-open position. The carburetter 31 is provided with fuel nozzles 54 and suction actuated metering needles 52 which are opened positively, when the throttle valves 44 are opened, by lugs 61 attached to levers 57 actuated from. the throttle valves 44. An acceleration pump 80 delivering through a passage 81 is also actuated by a link 75 from the throttle valves. The manifold riser 15 may be heated by an exhaust jacket 26.

Title: Improvements in high frequency electrical oscillators
IPC: H01J25/12
Filed: 1941-03-05
Abstract: 585,209. Velocity - modulated tubes. SAYERS, J., OLIPHANT, M. L. E., and WRIGHT, C. S. March 5, 1941, No. 2990. [Class 39 (i)] A velocity-modulated high-frequency oscillator is characterised by the pole extremity 5, of either or both of the oscillatory systems, being shielded from direct impact by the electron beam, thereby preventing bombardment of this pole extremity by any electrons travelling in divergent paths, with consequent secondary emission and loss of efficiency. The shielding may be effected as shown by setting- back the pole 5 relatively to the pole 5 <1>. Alternatively the pole extremities may be in the same plane and a guard protuberance be formed on the pole 51. The electron beam emanating from the cathode 13 may be focused by auxiliary electrodes 14 which would cause, apart from space charge, convergence and crossing of the beam between the two oscillatory systems ; the space charge causes such a convergent beam to become approximately parallel. The section shown in the drawing may be rotated about the axis AA, or as disclosed in Specification 585,208, it may be rotated about the axis BB, or moved parallel to itself.
