  • Patent number: 12257547
    Abstract: A direct air capture system includes a frame arranged to define a first adsorption unit and a second adsorption unit arranged around a central axis, a first adsorption cell disposed in the first adsorption unit and a second adsorption cell disposed in the second adsorption unit, each including a first opening and a second opening, a hub rotatably coupled to the frame for rotation around the central axis, an upper arm and a lower arm each coupled to the hub for co-rotation around the central axis, and an upper lid coupled to the upper arm and a lower lid coupled to the lower arm, both movable between an open position and a closed position. The upper arm and the lower arm are movable so that the upper and lower lids are positioned concentric with the first opening and the second opening, respectively.

  • Publication number: 20080140746
    Abstract: A system and method efficiently prepare the initial state of q quantum computer required by the eigenvalue approximation method of Abrams and Lloyd. The system and method can be applied when solving continuous Hermitian eigenproblems, e.g. the Schrodinger equation, on a discrete gird, and allows for efficient calculation of their eigenvalues with quantum computers. A system and method efficiently prepare an approximate initial state (not limited to eigenvectors) of a quantum computer required by a quantum algorithm as input.

  • Patent number: 5200551
    Abstract: The present invention relates to an improved method for the preparation of an intermediate for bambuterol, i.e. for the preparation of 2'-bromo-3,5-di[N,N-dimethylcarbamoyloxy]acetophenone (1), by reacting 3,5-dihydroxyacetophenone with N,N-dimethylcarbamoylchloride in ethyl acetate, isopropylacetate, butylacetate, ethylmethylketone or isobutylmethylketone as a solvent with small amount of pyridine as a catalyst and using crystallized potassium carbonate as a base, quenching with water, removing the solvent and dissolving of the resulting 3,5-di[N,N-dimethylcarbamoyloxy]acetophenone in ethyl acetate, to which dissolved hydrogen bromide is added and then bromine, whereupon the resulting intermediate (1) is collected in the form of crystals.
