Title: Permanent Magnet Brushless Torque Actuator
Inventor: MOHLER DAVID B
IPC: H02K21/24
Filed: 1993-07-30
Abstract: A permanent magnet brushless torque actuator is comprised of an electromagnetic core capable of generating an elongated toroidally shaped magnet flux field when energized.  Outside the generally cylindrical coil is an outer housing with upper and lower end plates at each end. Mounted to the end plates and extending towards each other are stator pole pieces separated from its opposing pole piece by an air gap.  A permanent magnet rotor is disposed in the air gap and mounted on a shaft which in turn is rotatably mounted in each of the end plates.  The permanent magnet rotor comprises at least two permanent magnets, each covering an arcuate portion of the rotor and having opposite polarities.  Energization of the coil with current in one direction magnetizes the pole pieces such that each of the two pole pieces attracts one of the magnets of the rotor and repels the other magnet of the rotor resulting in a torque generated by the output shaft.  Reversal of the current flow results in a reversal of the torque and rotation of the rotor in the opposite direction.  Preferred embodiments are disclosed having multiple cells, i.e. a plurality of stator rotor stator combinations and/or cells in which there are a plurality of pole pieces at each stator pole plane.
Patent CA-2102388-A1 (CA)
Title: Hose cross over device
Inventor: DOKNJAS MICHAEL J
IPC: F16L41/03
Filed: 1993-11-03
Abstract: ABSTRACT     The device relies on two manifolds. One divides the water flow into several smaller diameter hoses that lay parallel on the ground surface. Theother collects the water from the smaller diameter hoses. These manifolds are constructed from material which withstands both internal water pressure and the external force of a heavy vehicle inadvertently crossing over it. Water flow would not be compromised while in these manifolds. The small diameter high pressure hoses have a total sum flow capacity greater than the input/output connections. A greater friction loss is experienced with smaller diameter hoses and with vehicles compressing some hoses when crossing over. This flow reduction is eliminated by adding more small diameter hoses. A centre manifold that would allow an additional lane of traffic to cross over, could be added. This centre manifold redirects water flow to all hoses on opposite side. This means compression of hoses on one side does not have water restriction to any hose on the opposite side. Protective coverings can also be added to protect hoses from the ground and damage caused by vehicle braking. The manifolds would have small water vents that would produce a spray. The top covers would have a surface that, when sprayed by water from the manifold vents, would produce a somewhat slippery surface. This would still allow vehicles to brake safely on the top cover without causing damage to the smaller diameter high pressure hoses.
