Thin Film Superconducting Synchronous Motor
Thin Film Superconducting Synchronous Motor
US Patent:
6711422, Mar 23, 2004
Filed:
Sep 17, 2001
Appl. No.:
09/953840
Inventors:
Osman K. Mawardi - Cleveland Heights OH 44106
International Classification:
H02K 5500
US Classification:
505166, 505120, 310 52, 310 54, 310261
Abstract:
An superconducting electric motor is operated as a traditional squirrel-cage induction motor until the rotor reaches synchronous speed, at which point a current is trapped in a superconducting film by heating a portion of the superconducting film above its critical temperature, allowing the magnetic field generated by the stator coils to penetrate into the superconducting material and to induce a current. The superconducting material is then allowed to cool down below its critical temperature, thus trapping the current and allowing the motor to operate as a synchronous motor utilizing the magnetic field created by the direct current circulating in the superconducting material.
Thin Film Superconducting Motor With Magnetically-Quenched Rotor
Thin Film Superconducting Motor With Magnetically-Quenched Rotor
US Patent:
6791229, Sep 14, 2004
Filed:
Sep 17, 2001
Appl. No.:
09/954245
Inventors:
Osman K. Mawardi - Cleveland Heights OH 44106
International Classification:
H02K 5500
US Classification:
310211, 310261, 310166, 310 52, 505166
Abstract:
A superconductor motor operates as a squirrel cage induction motor. The rotor is covered with a thin film of superconducting material and the magnetic field created by the stator is strong enough to quench the superconducting material to its normal state at periodic spots on the rotor. This periodic quenching both creates a squirrel cage configuration of superconducting material on the rotor and allows the stator field to penetrate the rotor to induce a current. Once the squirrel cage is âcreatedâ by the stator field and a current induced, the motor operates as a conventional squirrel cage induction motor.
Magnetic Separation Of Iron Pyrite From Coal
Magnetic Separation Of Iron Pyrite From Coal
US Patent:
4157953, Jun 12, 1979
Filed:
Jan 28, 1977
Appl. No.:
5/763571
Inventors:
Osman K. Mawardi - Cleveland Heights OH
International Classification:
B03C 110
US Classification:
209213
Abstract:
A high gradient magnetic separator particularly for the desulfurization of coal. The process and apparatus are continuous and suitable for high volumes of material in a fluid stream. They employ the concept of a high gradient magnetic field through a stream of material that has some portion of magnetic particles which are to be separated. Within the separator is a matrix of magnetizable material, such as stainless steel wool. A magnetic field is formed of a series of magnetic coils surrounding the stream of material from the inlet to an outlet. Each of the coils are magnetized and then demagnetized in sequence so as to drop or release magnetic particles from the steel wool to the fluid stream as it flows through the separator.
As the magnetic particles concentrate they are flushed out through a diverter valve for a short moment and the process continues. Passage of the stream of material is continuous for all practical purposes.
Beneficiating Ore By Magnetic Fractional Filtration Of Solutes
Beneficiating Ore By Magnetic Fractional Filtration Of Solutes
US Patent:
4539040, Sep 3, 1985
Filed:
Sep 20, 1982
Appl. No.:
6/420090
Inventors:
Osman K. Mawardi - Cleveland Heights OH
International Classification:
C22B 100
US Classification:
75 1R
Abstract:
One solute is selectively filtered from a mixture of solutes by making use of the difference between the magnetic susceptibilities of the solutes.
Fluid streams of the substances to be filtered are subjected to intense magnetic field gradients to effect the separation or filtration. At points of high magnetic gradient or intense magnetic field, the substance of greater magnetic susceptibility, or the paramagnetic substance distinguished from a non-paramagnetic substance, is deflected laterally through a path of variable resistance to flow so that it separates from non-paramagnetic substance.
Flow Sensor
Flow Sensor
US Patent:
4779458, Oct 25, 1988
Filed:
Dec 29, 1986
Appl. No.:
6/946911
Inventors:
Osman K. Mawardi - Cleveland Heights OH
International Classification:
G01F 168
US Classification:
374 41
Abstract:
A flow-sensing system is provided which employs a pair of sensing resistors. One of the resistors is disposed within flowing fluid, while the other is shielded from the flow. The sensor resistances are held constant by identical feedback circuits which maintain the relationship between current values in the sensors for this purpose. The required difference in currents in the two resistors enables fluid flow to be computed.
Input and output temperature sensors are provided to enable temperature difference to be measured and combined with fluid-flow to indicate the rates of BTU flow. One temperature sensor and the fluid-flow sensors constitute an assembly miniaturized in a solid state chip.
