  • Publication number: 20170144321
    Abstract: A sheet processing apparatus includes a punch mechanism disposed along a media path at a punch point at which a hole is to be punched through a punch location on a media sheet advancing along the media path. The punch mechanism includes a rotatable punch arm having a punch head, and a punch motor for rotating the punch arm. As the punch location on the advancing media sheet approaches the punch point, speed of the punch motor is controlled to adjust a rotational speed of the punch arm based on feedback signals associated with each of the punch motor and a media path motor used to advance the media sheet such that the punch head arrives at the punch point at substantially the same time as when the punch location on the media sheet arrives at the punch point.

  • Publication number: 20170051219
    Abstract: Provided herein are blends oils or fatty acids comprising more than 50% medium chain fatty acids, or the fatty acid alkyl esters thereof, and having low melting points. Such blends are useful as a fuel or as a starting material for the production of, for example, a biodiesel. Also provided genetically altered or modified plants, modified such that the amount of medium chain fatty acids generated by the plant are increased. Further provided is a method of predicting the melting point of a blend of fatty acid methyl esters and the use of such a method for identifying blends suitable for use as, for example, a biodiesel.

  • Patent number: 8400025
    Abstract: An apparatus and method for substantially reducing the electrical energy consumption of a.c. induction motor-driven appliances by connecting a database predetermined capacitance in parallel with the motor-driven appliances and connecting a database predetermined inductance in series with the a.c. induction motor-driven appliances to effect the optimal power factor correction and optimal inrush current limiting of such motor-driven appliances thereby conserving electrical energy and reducing electrical energy costs. The databases of the present invention which specify the optimal power factor correction capacitance value and an optimal inductance value for specific a.c. induction motor-driven appliances eliminates the need for preliminary power factor and inrush current related electrical measurements and making the mass production and sale of the present invention practical.
