Abstract: 1,128,629. Cathode constructions. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 25 Feb., 1966 [2 March. 1966], No. 8402/66. Heading HID. In an indirectly heated cathode for a cathoderay tube, the cathode plate 1 is supported at or near an aperture in a hollow spherical body and is heated by a heating element 7 located within the cavity 4 of the body. The heating element 7 is positioned so that it does not pass through the centre of the body, and the body, which is made in two halves 5, 6, has a reflecting inner surface. The cathode support strips 3, which may be of iron-nickel alloy, are secured to the inner cavity wall. The cathode, which may comprise a nickel plate 1 and which may be concave or form part of the surface of an ellipsoid, has an emissive coating 2 on its forward face and may be provided with edges 8 which, in conjunction with edges 9 on the lip of the aperture, prevent any light escaping into the tube. The rear surface of the cathode 1 and strips 3 may be coated with a dark-coloured substance, e.g. chromium oxide, to improve the heating of the cathode. The arrangement gives a heating-up period for the cathode of a few tenths of a second and dimensions of an arrangement are given in an example.

Title: Improvements in or relating to plows
IPC: A01B61/00
Filed: 1921-03-18
Abstract: 177,695. Pritzel, B. C. F. March 18, 1921. Ploughs with adjustable tool-frames.- A plough is provided with means whereby the shares, on. engaging an immovable obstacle, are automatically raised over the obstacle and introduced into the soil again. The shares 12, 13 are carried by a U-shaped frame 18 mounted at its front end on pivots 16 supported by and movable in guides 14 secured to a main frame 7. The rear end of the frame 18 is mounted on the cranked portion of a shaft 30 carried by bearings on the main frame and adapted to be driven by chain-and-sprocket gear from a member 35 on the shaft 36 of a supporting-wheel 9 of the main frame. The frame 18 is connected to the frame 7 by a coupling-member 19 having a head 20 adapted to be held between two curved jaws 21 pivoted at 22 to the frame 7. The jaws 21 are caused to grip the head by a spring 24 on a bolt 23 passing through the jaws. A spring 27 connects the rear ends of the plough frame and the main frame. The member 35 is adapted to be clutched to the hub of the wheel 9 but is normally freed there from by a bell-crank lever 38 engaged by the forward end of one of the slides supporting the pivots 16. When the shares engage an obstacle the plough frame slides backwards in the main frame, the head 20 slipping from between the jaws, the lever 38 is released, and a spring throws the clutch between the wheel 9 and the member 35 into gear. The crank-shaft 30 is thus rotated, lifting the rear end of the frame 18 and raising the shares over the obstacle. As the cranked portion moves forwards, the head 19 is brought into position for engagement by the jaws 21 and the slide 15 operates the lever 38 to throw out the clutch. The spring 27 then pulls the plough frame backwards causing the shares to enter the soil. The rear wheel 11 is provided with a height adjusting device.

Abstract: 253,650. Burleigh, J. W. April 8, 1925. Exciting.-In a variable-speed, constant-volts continuous-current generator having a doublywound armature with two commutators, the fixed windings are connected between one main brush and a subsidiary brush, both of which bear on the same commutator, the main brush being at the usual commutating position and the subsidiary brush being displaced therefrom. The two armature windings may be connected in series or in parallel. In the form shown in Fig. 1, a double armature bipolar machine with commutating poles 9 has a commutator 2 to which the main load 8 is connected and a second commutator 1 for exciting the fields, one of the exciting brushes 5 being displaced from the neutral position. The field coils 3 may both be connected to one pair of brushes 4, 5 in series, as shown, or two separate coils may be used, each connected to its own main and subsidiary brushes. In the form shown in Fig. 2, three brushes bear on the commutator 1, two of which, 4, 12, in the usual commutating position supply an external load 13 while the fields 3 are excited from the main brush 4 and a displaced auxiliary brush 5. The Specification describes also an arrangement in which the main load is supplied by both armatures in series while the fields are excited partly from an external source and partly by a coil connected between a displaced auxiliary brush on one commutator and one main brush on the same commutator. The partial excitation of the fields by an external source may be applied to any of the forms described. A commutating notch may be formed in the pole-face adjoining the brush 5 and neutralizing coils may be wound around a half of each pole face. Alternatively, the neutralizing coils may embrace the commutating poles, as shown at 15 in Fig. 5, or they may be extended further so as to spread from the central notch in one main pole to that in the next and enclose the commutating poles at their mid-points.
