20100317898 | NOVEL CATALYST FOR ALDOL CONDENSATION REACTIONS - Present invention presents catalytic systems for aldol condensation reactions. The efficiency of the catalytic systems of the present invention is comparable to those of the classical strong acid or strong base catalysts. | 12-16-2010 |
20120330002 | HETEROGENEOUS THIOL-ENE CLICK MODIFICATIONS OF SOLID POLYSACCHARIDE-BASED MATERIALS - This invention concerns the first environmentally benign heterogeneous modification of polysaccharide-based material in native solid state by thiol-ene “click chemistry”. The direct reaction of a thiol with an un-activated double or triple bond by thiol-ene and thiol-enyne click modification is thermally or photochemically catalyzed and is completely metal-free and allows for a highly modular approach to modifications of fibers and fiber-based materials. | 12-27-2012 |

20150176924 | COMBO-COOLER - A combo-cooler includes heat exchangers having parallel tubes corresponding to each heat exchanger aligned in a tube plane. A first end tank assembly includes a columnar end tank separated by a baffle into compartments each in fluid communication with a respective hydraulically independent fluid circuit. The second tank assembly includes manifolds aligned in a column. Serially adjacent manifolds are in slidable contact or separated by a respective gap to allow relative translation. Banks of the tubes are brazed in fluid communication with a compartment and a manifold to connect the compartment and the manifold to have a respective fluid flow therethrough. A bracket contacts at least two of the serially adjacent manifolds to prevent translation between the bracket and the serially adjacent manifolds perpendicular to the tube plane and to allow relative translation between the at least two of the serially adjacent manifolds parallel to the tubes. | 06-25-2015 |

20130006550 | IDENTIFYING ELECTRICAL SOURCES OF ACOUSTIC NOISE - Systems and methods of identifying electrical sources of audible acoustic noise may involve identifying first frequency content of a circuit board, wherein the first frequency content is associated with at least one of acoustic noise and a vibration of the circuit board. Second frequency content of an electrical signal associated with the circuit board may also be identified. In addition, a coherence between the first frequency content and the second frequency content may be determined. | 01-03-2013 |

20080298166 | Method and Apparatus for Preparation of Granulated Material - An apparatus for preparing samples of granulated material comprises an upper vessel having a floor including a plurality of planks, slots between each plank, and an open ceiling to allow passing of homogenized material, a lower vessel under the upper vessel and having a plurality of division plates that fit in the slots and form a plurality of compartments which hold samples, a feeder which oscillates over the upper surface of the upper vessel to render a homogenised and representative sample. The method comprises positioning the lower vessel under the upper vessel, feeding material to be sampled through the feeder by an oscillating movement, raising the lower vessel such that the division plates partition the heap of material to form a plurality of samples, removing planks from the upper vessel, thus forcing the plurality of samples to fall toward the compartments, and separating both the vessels to remove the samples. | 12-04-2008 |
