  • Patent number: 10471599
    Abstract: Systems and methods for determining item manipulation strategies using magnetic manipulation are described herein. For example, item information describing properties of an item may be accessed. The item information may indicate that the item includes a magnetic patch. Using this item information, a manipulation strategy for manipulating the item may be determined. The manipulation strategy may include a strategy for manipulating the item using one or more end effectors of a robotic manipulator. The manipulation strategy may be provided to the robotic manipulator for manipulation of the item by magnetically coupling an end effector of the one or more end effectors with the magnetic patch connected to the item.

  • Publication number: 20160068630
    Abstract: A process for the preparation of polycarbonates may include ring-opening polymerization of five-membered cyclic carbonates in the presence of a catalyst; a compound of formula (I), stereoisomers, racemics, or mixtures thereof; and optionally cyclic esters, stereoisomers, racemics, or mixtures thereof. Formula (I) is: Each dotted bond “a” and “b” is a solid bond, a wedged bond, or a hashed wedged bond. R21 and R22, taken together with the carbon atoms 4 and 5 of the cyclic carbonate, may form a ring. The ring may be a C5-9cycloalkylene, C5-9cycloalkenylene, or C6-12arylene. The ring may optionally be substituted with substituents including halo, hydroxyl, C1-6alkyl, haloC1-6alkyl, C1-6alkoxy, haloC1-6alkoxy, C6-12aryl, C1-6alkylthio, carboxyl, C1-6alkoxycarbonyl, C1-6alkylcarbonyloxy, amino; or mono- or di-C1-6alkylamino.

  • Patent number: 6410878
    Abstract: The invention concerns a method for producing a flame support for a gas burner, which consists in producing disjointed metal fibres (10) in an alloy comprising iron, chromium and aluminium; assembling the fibres together under pressure; bringing the fibre mat to a temperature sufficient to ensure a close bonding between the fibres. The invention is characterised in that it consists in feeding said metal alloy to an overflowing tank (3), to produce the fibres by cooling in contact with a mobile wheel (7); then in arranging in a moulding matrix the resulting disjointed fibres (10) and compressing them to form an agglomerated mat; then in connecting the mat to electrodes and a capacitor, thereby bringing the fibres (10), at their points of contact, to a temperature not less than their melting point, to produce fibres closely welded together, under high voltage.
