Abstract
Abstract Lateral guide means for a magnetically supported and track controlled vehicle. In a magnetically supported vehicle lateral guide means are provided for guiding same both along a straight or slightly curving portion of a track and for guiding same through a switch. One set of magnets is provided along one side of the vehicle and another set of magnets is provided along a guide rail adjacent the track. In one embodiment, either of said sets of magnets is a set of electromagnets and the other is a set of permanent magnets while in another embodiment all magnets are electromagnets. A similar arrangement is provided on the opposite side of the vehicle. By creating repelling forces between some of said magnets and attracting forces between others thereof, an accurately controllable lateral guide is developed for said vehicle by which same is caused to maintain an accurately controllable spacing between the vehicle and the side guiding means. A further modification includes combinations of linear motors on either side of the vehicle together with guiding magnets between the vehicle and a laterally positioned track.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
124 words
In a magnetic guide for a magnetic suspended railway in which vehicles are guided along and between stationary magnetically conductive rail means by means defining guide electromagnets arranged on opposite sides of each of said vehicles and, in a switch zone, a track change by said vehicle being accomplished through the effect of said guide electromagnet means being energized on only one vehicle side, comprising the improvement wherein said guide electromagnet means in said switching zone on said one side of said vehicle includes control means for effecting a generation of both attracting and repelling forces on said magnetically conductive rail means to effect a balanced lateral guiding of said vehicle along said magnetically conductive rail means on said one side of said vehicle.
Claim 2
Dependent Claim
124 words
In a magnetic guide for a magnetic suspended railway in which vehicles are guided along and between stationary magnetically conductive rail means by means defining guide electromagnets arranged on opposite sides of each of said vehicles and, in a switch zone, a track change by said vehicle being accomplished through the effect of said guide electromagnet means being energized on only one vehicle side, comprising the improvement wherein said guide electromagnet means in said switching zone on said one side of said vehicle includes control means for effecting a generation of both attracting and repelling forces on said magnetically conductive rail means to effect a balanced lateral guiding of said vehicle along said magnetically conductive rail means on said one side of said vehicle.
Claim 3
Dependent Claim
36 words
A magnetic guide according to claim 1, wherein said guide electromagnet means is mounted on said opposite sides of said vehicles and movable therewith; and wherein said magnetically conductive rail means includes permanent magnets mounted thereon.
Claim 4
Dependent Claim
59 words
A magnetic guide according to claim 1, wherein said guide electromagnet means is mounted on said opposite sides of said vehicles and movable therewith; and wherein said magnetically conductive rail means includes permanent magnets mounted thereon; and wherein said magnetically conductive rail means includes electromagnet means mounted thereon and second control means for controlling the magnetic field generated thereby.
Claim 5
Dependent Claim
44 words
A magnetic guide according to claim 3, wherein at least one of said first mentioned and said second mentioned control means generates an alternating polarity while the other of said first mentioned and said second mentioned control means generates a steady and unchanging polarity.
Claim 6
Dependent Claim
27 words
A magnetic guide according to claim 2, wherein said guide electromagnet means comprises a row of electromagnets, said control means effecting a generation of said alternating polarity.
Claim 7
Dependent Claim
23 words
A magnetic guide according to claim 2, wherein said magnetically conductive rail means includes a row of permanent magnets having alternatingly different polarity.
Claim 8
Dependent Claim
43 words
A magnetic guide according to claim 2, wherein said magnetically conductive rail means further includes electromagnet means mounted thereon and adapted to attract said one side of said vehicle, said permanent magnets being adapted to simultaneously repel said one side of said vehicle.
Claim 9
Dependent Claim
62 words
A magnetic guide according to claim 1, including conventional linear motor means for propelling said vehicle along said magnetically conductive rail means and consist of at least two armatures arranged on opposite sides of said vehicle both lying in a horizontal plane and stationary stators secured to said magnetically conductive rail means, said stators having a reduced width in the switch zone.
Claim 10
Dependent Claim
62 words
A magnetic guide according to claim 1, including conventional linear motor means for propelling said vehicle along said magnetically conductive rail means and consist of at least two armatures arranged on opposite sides of said vehicle both lying in a horizontal plane and stationary stators secured to said magnetically conductive rail means, said stators having a reduced width in the switch zone.
