Abstract: 646,546. Travelling-wave tubes. M-O VALVE CO., Ltd., HUMPHREYS, B. L., and KITE, L. V. May 27, 1948, No. 14327. [Class 39 (i)] A travelling wave tube 1 contains at least two substantially coaxial helical conductors along the path of the electron beam. The phase velocity frequency characteristic can be adjusted by choosing dimensions for the helices to a degree that would only be obtainable with the usual single helix if the latter were appreciably smaller than either of the multiple helices. The tube is provided with an electron gun 2 and a collecting electrode 3. The helices 4 and 5 are mounted between cylinders 9 and 11 which form wavetraps with cylinders 16 formed on input and output waveguides 13 and 17. The ends 10 and 12 of the helices couple the tube to the wave-guides. In limiting cases one of the helices may be a number of straight rods or a number of parallel rings.

May 14, 1934, No. 14566. [Class 38 (iv)] In an electric transmission system comprising an engine driven generator and a motor, the generator is used for the purpose of either supplying the motor or charging the battery and speed responsive switching means is provided for establishing connection between the generator and the battery along a predetermined speed range of the generator or engine, the motor being disconnected from the generator over this range. The switching means (Fig. 1) comprises a cylinder 9 fed with oil from a pump driven by the engine and containing a piston 11 pressing against a spring 12. The end of the piston rod 13 is connected by a pin and slot to one end of a lever 14 which is adapted at one point to bridge two resilient contacts 19. When the engine speed is not sufficient to drive the motor, the oil pressure drops and the piston 11 is forced downwards into a position in which the contactor 17 bridges the contacts 19 and the battery is charged by the generator. When the engine speed falls to a lower value, the piston moves down and the contactor 17 breaks the connection to the battery. In Fig. 3 the lever 14 is pivotally connected to a rod 20 which coacts with the sleeve 21 of a governor driven by the engine. A dashpot 24 and plunger 23 retard the motion of the rod 20.
