  • Patent number: 8928290
    Abstract: A set of electric motor drives for recapturing otherwise unused electrical energy from electric motors and methods of using same are disclosed that provide electrical energy in addition to mechanical energy by recapturing electrical energy that would be unused if conventional technologies were followed. Such recapturing motor drives can provide recaptured electrical energy to other loads, can transfer recaptured electrical energy to storage devices for future use, and/or can recirculate recaptured electrical energy back through a recapturing motor drive. By recapturing unused electrical energy, the recapturing motor drives enable significantly greater useful energy output for any given electrical energy input drawn from a power source as compared to conventional technologies, materially increasing the efficient use of electrical energy drawn from the power source and dramatically reducing the relative consumption of electrical energy drawn from the power source.

Such recapturing motor drives can provide recaptured electrical energy to other loads, can transfer recaptured electrical energy to storage devices for future use, and/or can recirculate recaptured electrical energy back through a recapturing motor drive. By recapturing unused electrical energy, the recapturing motor drives generate significantly greater over-all energy output for any given electrical energy input drawn from any power source, thereby materially increasing the efficient and effective use of electrical energy drawn from the power source and dramatically reducing the relative consumption of electrical energy drawn from the power source.

  • Patent number: 4888282
    Abstract: A synthetic gene which encodes for acyl carrier protein (ACP) has been designed. Construction, cloning, and expression in E. coli of spinach ACP-I has been demonstrated. In vitro production of ACP by appropriate expression vectors carrying the synthetic gene will augment the meager supply of this protein. Analogous genes designed for expression of ACP in plants would be a useful tool for controlling fatty acid synthesis and metabolism.
