Patent GB-926568-A (GB)
Abstract: 926,568. Electric motors. Y. NIEDA. March 1, 1960 [March 30, 1959 ; April 17, 1959], No. 7191/60. Classes 35 and 38 (2). [Also in Group XXXVI] In a small D.C. electric motor commutation is effected by a Hall plate 3 rotating with the armature winding 5. Supply current I fed through bearings and flowing between terminal plates 8, 9 of the Hall plate causes a Hall current i to flow in winding 5 and this interacts with the magnetic field 10 to produce a torque. When the armature has turned over, the flux passing in the reverse direction through the Hall plate causes a reversed current i in the winding which since this is now under the opposite pole, produces a torque in the same direction. The Hall plate is preferably of indium antimonide. To overcome the difficulty of starting the motor when the Hall plate is parallel to the magnetic field a plurality of angularly-separated series connected plates and coils are used. Fig. 6 (not shown). The motor can also operate with an alternating flux applied since a simultaneous current reversal in the armature winding produces a torque in a constant direction. The machine can also be used as a generator to produce a half sine-wave output voltage between terminal plates 8, 9 and increasing the number of armature windings and Hall plates will reduce the nipple factor of this output. A modification slows the machine, having the Hall plates attached to a plastic cylinder which is free to rotate between an inner magnet, which may be an electromagnet, and the casing, the coils being wound around the outside of the cylinder.

Patent GB-2291074-A (GB)
Title: Anti-seismic arrangement for static electrical converter
Inventor: BUCKINGHAM ANDREW DOUGLAS JOHN
IPC: E04H9/02
Filed: 1994-06-30
Abstract: A static electrical converter arrangement comprises a valve assembly 12 mounted on a raft 15, the raft being suspended at each of two opposite ends from a series of rods 23 which are attached in a spaced-out relationship to a horizontal beam 22, the beam being mounted on the ground via rubber springs 24. During an earthquake, movement of the ground causes mainly lateral distortion of the rubber springs and elastic bending of the rods, and, since the natural resonant frequency of the suspension system is designed to be low and the rubber springs are designed to have significant damping, a high degree of isolation is provided for the raft and the equipment mounted on it. During severe earthquakes, the rods are arranged to suffer a plastic bending which causes them to act like pendulums and lowers the natural frequency of the suspension system even further to provide greater protection. Ideally, the tops of the rods are arranged to be level with the combined centre of mass of the valve assembly and the raft so that the valve assembly is prevented from experiencing a bending moment about the combined centre of mass. <IMAGE>
