IPC: H02K49/10
Filed: 1958-02-14
Abstract: 887,143. Magnetic couplings. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 22, 1959 [Feb. 14, 1958], No. 4941/58. Class 35. A continuously variable ratio magnetic coupling, e.g. for alternators driven from aircraft engines, comprises input and output discs or rings 1, 5 and an intermediate disc or ring 3 whose axis may be moved transversely. As shown, the input and output members have peripheral magnetic inserts 2 and 6 respectively and the intermediate member is of conducting material, but the converse arrangement could be used. The inserts may be permanent magnets or be of magnetic material energized by an external, stationary, permanent or electromagnet, in all cases the magnetization being axial. With external magnetization the conductive members may be ferromagnetic to reduce reluctance, the various axles and supports being of non-magnetic material, e.g. stainless steel. It is shown that the relative speeds and directions of rotation of the members depends upon the angles of intersection of their peripheries and, in particular, it is described how a theoretical four to one variation in output speed may be obtained. For greater speed variations several units may be used in cascade. In an alternative arrangement (Figs. 4-6, not shown), the input and output members are on the same side of the intermediate disc and there may be several discs or rings on each shaft.

Title: Improvements in and relating to the generation of high frequency alternating electric current
IPC: H03B1/00
Filed: 1921-02-15
Abstract: 180,400. British Thomson - Houston Co., Ltd., and Alexanderson, F. W. Feb. 15, 1921. Equalizing load on generator.-A high-frequency generating-system, particularly applicable to wireless signalling, comprises a high-frequency alternator and a vacuum tube amplifying or generating set working in parallel or in series therewith. As shown in Fig. 1, one of the windings 3 of an alternator 1 of the Alexanderson type is connected through a phase-rotater 7 and a wave-shape transformer 8 to the input circuit of a thermionic amplifier 6, the output circuit of which contains a direct-current source 9. The amplified energy is fed to the antenna 5 through a transformer 10, and is of the same frequency and phase as that supplied direct by the alternator through the transformer 4 as in Specification 149,409, [Class 38 (iii), Electric motor control systems &c.]. Signals are transmitted by means of a key 12 controlling a magnetic modulator 11, as described in Specification 103,842. Fig. 2 shows the system as applied to an alternator not provided with separate windings. The whole output of the alternator is fed to the antenna 5 through a transformer 13, the secondary of which is short-circuited by the magnetic controller 11 when the signalling-key 12 is in the position shown. The input circuit of the valve amplifier 14 comprises a phase-rotator 15 and is shunted across the secondary of the transformer 13, whilst the output is fed to the antenna through a transformer 16. In order to render the valve 14 inactive when no signalling energy is being supplied to the antenna, i.e. when the transformer secondary 13 is short-circuited, the key 12 opens contacts 20 and thereby imposes a blocking negative potential from a battery 17 upon the grid of the valve 14. During signalling, the key short-circuits the battery 17, and by removing the negative potential causes the amplifier 14 to function in synchronism with the alternator 1.
