A change-speed transmission device comprises driving and driven shafts 1, 6 respectively, a friction disc 4 of an electromagnetic clutch which is engaged by a flywheel 2 when current is passed through an electromagnet 3, and an electrically operated change-speed and reverse gear 5. The gear mechanism 5 is controlled by a selector 18 energising solenoids 21-25, each of which causes the engagement of a different speed ratio. A solenoid 16 is connected in series with the solenoids 21-25 and locks the mechanism 5 in each of its working positions, being engaged under the control of the electric selector switch 18 when the gears are engaged, but short circuited by a switch 17 closed mechanically by the gear when the latter is in neutral. The electromagnet 3 is controlled by a clutch actuating switch 8. Both the selector 18 and switch 8 are mechanically coupled to a control lever 7, the interconnection being such that the clutch is disengaged when the lever is moved to change speed. Current is provided by a dynamo 11 driven at a speed proportional to that of the driving shaft 1, which thereby affords an additional controlling means for the electromagnet 3. The dynamo also charges a battery of accumulators 12. The invention is particularly applicable to vehicles and to machine tools. In the later case the dynamo 11 may be replaced by other regulating means, such as a variable resistance controlled by a centrifugal or other governor.

Abstract: 632,210. Magnetrons. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 27, 1947, No. 5658. Convention date, Oct. 31, 1945. [Class 39 (i)] [Also in Group XL (c)] A magnetron of the split-anode type has an evacuated cylindrical metal envelope closed by ferromagnetic end-plates, a magnet coil coaxial with and surrounding the envelope, and an external shell of ferromagnetic material which with the end-plates provides a substantially complete electromagnetic enclosure and a uniform field. A cylindrical anode chamber 11 has end-plates or pole-pieces 13, 15 of iron or steel, and a connecting cylindrical wall 17 which is saturable bv the magnetic flux. An external shell 23 and flat ring-like plates 21 also of ferromagnetic material surround the coil 19. A cylindrical cathode 25 of the secondary emitter type is supported on a long hollow stem 29 which is supported from plate 15 by a tubular member 33 insulated by a glass seal 35. A quarter-wave choke 36 is provided. Cooling fluid circulates inside the cathode. Two semi-cylindrical anode members 45, 47, of copper, are supported on posts 49, 51, with which they may be integral, and are connected by frequency lead tubes 53, 55 to the lower end-plate 13. Cooling fluid circulates through hollows in the posts, anode plates, endplates and tubes. A tuning-ring 67 is supported from a ring 71 which is movable up and down by a screw 73, upon rotation of a sleeve 75. The movement of the ring 67 is controlled by guides and a bellows connection surrounding the posts permits movement without affecting the vacuum within the chamber. In its upper position the tuning ring closely embraces posts 49, 51 and consequently gives a wide tuning range. A dome 81, e.g. of glass, is sealed across the lower end-plate 13 and a hollow wave-guide 89 is secured to the supporting plate 22. A sheet-metal shield 91, with projecting shieldportions 93, is connected across the outer ends of coupling loops 53, 55 to prevent electrons escaping into dome 81. A copper-plated steel ring 87 prevents eddy current heating of the dome seal 83. The coupling to the wave-guide 89 may be increased by providing depending vanes on the shield 91, or a dome-like structure attached to the output loops 53, 55, and lying within the dome 81. The resonant circuit of the magnetron comprises the inductance of posts 49, 51, and the capacitance of anodo members 45, 47, and the tubes 53, 55 are the coupling loops.

Abstract: 693,567. Thermionic valves. SYLVANIA ELECTRIC PRODUCTS, Inc. March 7, 1950 [March 9, 1949], No. 5800/50. Class 39(i). the laterals 28 of an electron discharge tube grid have straight end portions, and a reversed arcuate intermediate portion 41 with the concave side towards the cathode 16; heating causes the straight portions to expand towards the cathode, but the curved portion to expand away from the cathode, thus tending to eliminate or minimize variation in the average cathode/grid spacing and hence the tranconductance. In Fig. 3 the arrangement is applied to both grids of a double triode. In Fig. 4, in which the grids are connected together, only one grid 40 is of the above-described shape, the other grid 18 having a convex arcuate portion towards the cathode. The dimensions are so chosen that the reduction in cathode/grid spacing as grid 18 expands is just compensated by the increased spacing of grid 40, so that the overall transconductance is unaltered. The two grids may have dissimilar coefficients of expansion, and the arcuate portions may be of different curvatures.
