Abstract
Abstract A combined fluid and magnetic energy transmission system is developed whereby velocity is imparted to a fluid recirculating in a closed-loop, non-magnetic piping configuration and to ferromagnetic slugs spaced at regular intervals in piping. The velocity of the slugs is imparted to a carrier associated with and on the exterior of the piping by means of a permanent magnet incorporated with the carrier. Instead of being associated with a carrier, the permanent magnet can be connected with other mechanical components to deliver mechanical energy.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
145 words
A system for transmitting mechanical energy from one location to another in a defined path, said system comprising, in combination a conduit of nonmagnetic and nonmagnetizable material; means for pumping fluid through the conduit; a slug in the form of a stable, nondeformable ferromagnetic mass, said slug located within said conduit and free to move with said fluid and so shaped that it includes a portion which substantially conforms in cross sectional configuration to the configuration of the interior of the conduit whereby to inhibit any substantial by-pass of fluid past the slug thereby to cause the fluid to impart a velocity to the slug substantially equal to that of the slug; and a permanent magnet located outside the conduit and supported for movement along the conduit, said permanent magnet moving with the slug when the latter is in the magnetic field of the magnet.
Claim 2
Independent Claim
145 words
A system for transmitting mechanical energy from one location to another in a defined path, said system comprising, in combination a conduit of nonmagnetic and nonmagnetizable material; means for pumping fluid through the conduit; a slug in the form of a stable, nondeformable ferromagnetic mass, said slug located within said conduit and free to move with said fluid and so shaped that it includes a portion which substantially conforms in cross sectional configuration to the configuration of the interior of the conduit whereby to inhibit any substantial by-pass of fluid past the slug thereby to cause the fluid to impart a velocity to the slug substantially equal to that of the slug; and a permanent magnet located outside the conduit and supported for movement along the conduit, said permanent magnet moving with the slug when the latter is in the magnetic field of the magnet.
Claim 3
Dependent Claim
26 words
A system as in claim 1, said slug including sealing means engaging the interior walls of said conduit and blocking flow of fluid past the slug.
Claim 4
Dependent Claim
29 words
A system as in claim 2, said sealing means including flexible skirting around the slug with the free edge of the skirting in sealing contact with the conduit wall.
Claim 5
Dependent Claim
34 words
A system as in claim 1, including a plurality of said slugs of magnetic material, and means for maintaining the slugs at a predetermined spacing relative to one another along the conduit during movement.
Claim 6
Dependent Claim
16 words
A system as in claim 4, said spacing means comprising spherical elements interposed between successive slugs.
Claim 7
Dependent Claim
88 words
The combination as in claim 1, including a carrier supported on the conduit, said permanent magnet connected with said carrier, said conduit provided with track means along at least a portion of the length thereof in the form of a pair of laterally spaced grooves extending along the exterior of said conduit portion, said carrier including track engaging members for following said track and stabilizing the carrier with respect to the conduit, said track engaging members comprising balls partially caged in the carrier and riding in the grooves.
Claim 8
Dependent Claim
44 words
A system as in claim 1, including means associated with said conduit and operable in response to movement of said magnet passed a predetermined point to separate said magnet laterally away from said conduit thereby to break the bond between the magnet and slug.
