IPC: G01D5/22
Filed: 1956-09-25
Abstract: 844,051. Controlled non-linear inductors. ENGLISH ELECTRIC CO. Ltd. Sept. 25, 1956 [Sept. 27, 1955], No. 27466/55. Class 40 (9). [Also in Groups XXXV and XXXVI] A fixed magnetic circuit including air gaps and a constant source of magneto-motive force (eg. permanent magnets) is unbalanced when an armature on a lift cage approaches the gaps. A flux detector comprising saturable reactors responds to the flux change and operates an indicator. In one arrangement, Fig. 1, the fluxes from two permanent magnets 12, 13 normally circulate in the air gaps between a central member 14a and wing-like members 11a, the fluxes being in opposition in limb 11. When the lift approaches from above, an armature 16 unbalances the circuit and the flux detector 10 gives an indication of one polarity. When the two armatures 15, 16 produce similar conditions in the two gaps, the detector gives a zero indication and as armature 16 leaves the gap the detector gives an indication of the opposite polarity. The flux detector 22, Fig. 2, may be arranged in the central limb of a three-limbed core, the permanent magnets 23, 24 producing fluxes in opposition in the central limb. In another arrangement, Fig. 3, a detector 34 forms a junction between two parallel magnetic circuits identified with the magnets 30, 31 and limbs 33a, 33b. The member 32 is common to the two circuits. Only one armature 35 is used in this arrangement. The flux from both magnets tends to flow through the air gap with the least reluctance.

[Class 39 (i)] In an electron-discharge device, particularly suitable for operation with short wavelengths of 10 metres or less, the connecting means for at least one electrode is or are fused to an insulating member of ceramic material which constitutes the closure member for a metal vessel which acts both as plate electrode and as part of the envelope. In modifications, the metal vessel is replaced by a metallized ceramic vessel. In the form shown in Fig. 1, the metal anode 1 is closed by a ceramic member 7 through which pass the leads to the cathode 2 and grid 3. Intermediate layers of glass are provided between these leads and the member 7, as also between the anode 1 and the member 7. A glass exhaust tube 8 is sealed into the ceramic insulator and when sealed off is protected by a layer of insulating compound. Pins 10 enable a bayonet connection to the anode to be made. In a modification the tapered portion 9 of the anode is replaced by an enlarged shouldered portion into which the ceramic plug fits, and a metallic exhaust tube is fixed into the bottom of the metal anode. In the form shown in Fig. 3, a ceramic body H of H-shaped crosssection is metallized internally at M to form the anode, and the leads to the other electrodes pass through the ceramic closure member J. The pump connection P, of glass or metal, passes through the cross-wall Q and is protected by sealing compound V. If of metal, the member P may also act as the anode lead. Ducts L are provided in the wall of the envelope for circulation of cooling medium such as water. In a modification, the grid and cathode leads are sealed through a ceramic plug which is separated from the main ceramic body by an intermediate glass member, which may be easily broken when it is desired to replace the cathode. The outer wall of the ceramic envelope may bear metallic coatings arranged to act as condensers or inductances for the oscillating circuit. Specifications 445,286 and 445,287 are referred to. The Specification as open to inspection under Sect. 91 includes also sealing the connecting or supporting means for electrodes of an electron discharge device into an insulating ceramic member, and constructing the envelope of such a device as a hollow ceramic body. This subject-matter does not appear in the Specification as accepted.

A toy comprises a model aircraft 18 carried on an upwardly bent rod 16 pivotally mounted about an axis 17 on a vertical drive shaft 14 in such a manner that the model 18 and a counterbalance weight can at one time be above the axis 17, and may therefore then only be in anything like stable equilibrium while the shaft is rotated at a constant velocity. The drive shaft 14 is driven manually by means of a bulb 28, air bellows 32 and a rod 54, the pulsing of which drives the shaft 14 through the medium of a ratchet and pawl 64, 66. An element of skill is necessary to control elevation of the aircraft, and depending on whether the aircraft or the counterbalance weight is above the axis of pivotation 17, the drive must be slowed or quickened, respectively, to increase elevation of the aircraft. The shaft 14 is slowed by pressing the bulb 28 extra hard, whereupon the rod 54 is moved to a position to apply a brake 84b to a drum 82 on shaft 14. The apparatus may be used as a competitive device whereby competitors are required to displace numbered tabs 104 by the wing of the aircraft 18.
