Title: Improvements in or relating to magnetron tubes and circuit arrangements incorporating the same
IPC: H03F1/16
Filed: 1936-10-16
Abstract: 468,596. Thermionic valves. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Oct. 16, 1936, No. 28203. Convention date, Oct. 16, 1935. [Class 39 (i)] A magnetron has an axial cathode arranged within a number of anodes and auxiliary electrodes, the anodes being so shaped and arranged that they or their continuations touch an imaginary circular cylinder concentric with the cathode, each at one place, the auxiliary electrodes being arranged outside the cylinder. The arrangement is such that the electron paths proceed tangentially to the anodes, and the auxiliary electrodes are almost free of the circulating electrons. As shown in Fig. 1, four flat anodes A are arranged on the sides of a square about a cathode K and auxiliary rod electrodes H are arranged within the corners but outside the imaginary cylinder touching the anodes; in a modification, Fig. 2 (not shown), the auxiliary electrodes are narrow plates arranged across the corners of the square. In another arrangement, Fig. 4 (not shown), the anodes are V-shaped. As shown in Fig. 5, the auxiliary electrodes H are in the same planes as the associated anodes A. In a further arrangement, Fig. 3 (not shown), two anodes and two auxiliary electrodes form the sides of a rectangle, the anodes being wider than the auxiliary electrodes.

In the arrangement shown in Figs. 1 and 2 the tracks 5, 7 and 23 are secured to the door frame and are engaged respectively by followers pivotable about vertical axis 3, and by follower 22 mounted on the door. To move the door from the closed position A shown the linkage carrying the first two followers is pivoted e.g. by driving follower 6 along track 5 using a drive chain (not shown) and the edge of the door moves outwardly, sliding movement along the tracks can now be effected - follower 22 on the trailing edge of the door being guided out of the frame by the curved track 23. In the embodiments shown in Figs. 5 and 6 the tracks are mounted on the door and the followers on the door frame. In Fig. 5 followers 45, 47 are pivoted about axis 44 on an arm 43 which projects from the frame. In Fig. 6 the followers 65, 67 are pivoted about axis 64 on the frame itself. In these embodiments third tracks 33, 50 are extensions of tracks 48, 69.  Suitable track and follower constructions are disclosed (Figs. 3, 7, 8, not shown). The lower corners of the door can have alternative securing and guiding arrangements. As shown in Fig. 1 a spring loaded pin 11 is pivoted to the frame and engages in channel 10 on the door as the door closes, (Figs. 4a, b not shown). In Fig. 2 a stud upstanding from the floor can enter a door slot 24.

[Also in Division F4] Dust in a hopper 1 downstream of a pressurized gas filtering unit is fed by a screw 2 in an inclined tube 3 down to a chamber 5 during which passage water from nozzles 4 is injected into the stream and the resulting mixture is compressed by the screw into a plug S prior to entering the chamber 5. The flute 2a of the screw 2 extends short of the downstream end of the tube 3 which is blocked by a movable stop T facilitating the formation of the plug in the flute free end of the tube. The upstream end of the screw is housed in a trough 6 joined to the tube 3 and sealingly connected to the bottom of the hopper 1. The shaft 10 of the screw extends through the chamber 5 and is driven by a motor 14 via transmission 11, 12, 13. Three nozzles 4 spaced along the tube 3 and at circumferential angular spacings of 60 degrees direct their jets into the screw shaft 10. A dust level control solenoid valve in the pressurized water flow to the nozzles, interrupts the flow if the hopper 1 runs out of dust. The chamber 5 is connected to a silo 22 by a tube 23.

Abstract: 279,857. Schering-Kahlbaum Akt.- Ges., (formerly Chemische Fabrik auf Actien vorm. E. Schering). Oct. 26, 1926, [Convention date]. Phenols; coumaranes. - Methylisopropylenephenols and dimethylcoumaranes are obtained by bringing the etheric condensation products of m- and p-cresol with acetone into contact with an inert porous material at elevated temperature, preferably at or about boiling temperature. The process may be effected under reduced pressure. Porous materials mentioned are bleaching earths, such as frankonite and tonsil, fuller's earth, diatomite, silica gel and charcoal ; their activity may be immersed by depositing thereon a metal of the nickel group or a compound thereof, e.g. nickel or its oxide. The products may be hydrogenated to thymol and menthol, as described, for example, in Specification 279,855. According to the examples the condensation product of mcresol and acetone is slowly distilled over frankonite heated to 320‹ C., or over nickelcoated silica gel heated to 300‹ C. and with exclusion of air, whereby a mixture of 3-methyl-6- isopropylenephenol and 3 : 6-dimethyleoumarane is produced; the condensation product of p-cresol and acetone under the same conditions yields 4- methyl-6-isopropylenephenol together with 3 : 5- dimethyleoumarane. Specifications 273,684 and 273,686 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that other ketone condensation products with m- and p-cresol behave similarly. This subject-matter does not appear in the Specification as accepted.

Abstract: 600,433. Wave-guides ; directive radio systems. BOOKER, H. G. Oct. 31, 1945, No. 28911. [Class 40 (vii)] A device such as a wave - guide horn or mirror has means for controlling the wave energy passing into or out of the device, comprising a plate of conductive material placed normal to the direction of propagation and formed with a plurality of resonant slots. Fig. 1 shows a parabolic reflector 10 fed by a wave-guide horn 15. The aperture is closed by a conducting plate 13 , formed with a plurality of linear slots 14. Slots 14 are one half-wavelength long and the .same distance apart, and thus are transparent to waves of this wavelength having the electric vector at right angles to the slots. The bandwidth of the transmitted energy depends on the width of the slots, while a departure from the resonant length effects a control of the phase of the transmitted energy. The density of the slots per unit area determines the amplitude of the energy in the corresponding part of the beam. By making the above factors different in different parts of the beam, the polar diagram may be modified as desired. Fig. 2 shows a spherically-shaped apertured plate 20 for use with a spherical wave front produced by a wave-guide 16a and a reflector plate 19. A second apertured plate 14a may be used. In Fig. 3, three apertured plates 13b, 13c, 13d are used in a wave-guide horn 21 to improve impedance matching. To alter the density of the apertures per unit area some of the slots may be effectively blocked by shortcircuiting their central region as at 24, Fig. 6. The length of a slot may be altered by means of a rotatable snail cam plate 23. For highpower working the slots may be filled with a suitable dielectric.
