  • Publication number: 20190321717
    Abstract: A system and method of shuffling decks of cards is disclosed including verifying that the shuffled deck of cards has the same number of cards as the deck of cards had had when a manual verification process was performed at the initiation of use of the deck of cards. Using the measured weight of the deck of cards after completion of shuffling, the number of cards in the shuffled deck of cards is verified. A cut card may be introduced to reduce the possibility of exposing the hole card to view. Two decks of cards may be used in sequence so that a first deck of cards is being used to play the game of cards while the second deck of cards is being shuffled and verified.

  • Publication number: 20180355327
    Abstract: The present invention relates to the production of a non-transgenic plant resistant or tolerant to a herbicide of the phosphonomethylglycine family, e.g., glyphosate. The present invention also relates to the use of a recombinagenic oligonucleobase to make a desired mutation in the chromosomal or episomal sequences of a plant in the gene encoding for 5-enol pyruvylshikimate-3-phosphate synthase (EPSPS). The mutated protein, which substantially maintains the catalytic activity of the wild-type protein, allows for increased resistance or tolerance of the plant to a herbicide of the phosphonomethylglycine family, and allows for the substantially normal growth or development of the plant, its organs, tissues or cells as compared to the wild-type plant irrespective of the presence or absence of the herbicide.

  • Patent number: 10100334
    Abstract: Provided herein compositions and methods for producing isoprenoids, including squalene. In certain aspects and embodiments provided are genetically altered yeast and uses therefore. In some aspects and embodiments, the genetically altered yeast produce isoprenoids, preferably squalene. The genetically altered yeast may have alterations in the expression or activity of enzymes involved in squalene production, for example, acetyl-CoA carboxylase (or “ACCase”), HMG-CoA reductase, squalene epoxidase, and squalene synthase. One or more genes of a genetically altered yeast may be modified by gene repair oligonucleobases. Also are provided methods of producing squalene using a genetically altered yeast. The invention also provides squalene produced by genetically altered yeast.

  • Patent number: 10071494
    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.

  • Patent number: 9796938
    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.

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.
