  • Patent number: 7998537
    Abstract: Methods for removing hydrogen from molecules are disclosed. In one embodiment, hydrogen-containing molecules are deposited on a solid substrate and are bombarded with hydrogen projectile particles. The particles may have energies of 5-100 eV, or more preferably 10-50 eV. The hydrogen projectile particles remove hydrogen atoms from the deposited molecules while they are on the substrate, without removing other atoms from the molecules. Dangling bonds are created by the loss of hydrogen and can be used to cross-link the molecules. The resulting product can be a nanometer-thick dense film.

  • Patent number: 7993859
    Abstract: The present invention relates to methods for detecting a oxidative stress in a biological sample, methods of determining a cumulative record of oxidative injury, and methods of diagnosing diseases of aging, such as cardiovascular diseases, based on the presence or absence of a biomarker or a component thereof. The present invention also relates to a kit for detecting oxidative stress in a biological sample comprising a stabilizing reactant and an antibody. In some embodiments of the invention, the biomarker of oxidative stress is selected from an aldehyde-protein adduct and an aldehyde metabolite-protein adduct, and the proposed method further comprises measuring separately for the same protein biomarkers of oxydative stress formed with different amino acids of the protein.

  • Patent number: 7987870
    Abstract: The invention relates to a protection device which defines a through hole (21) for the passage of a fluid which may be under overpressure conditions. In addition, the inventive device comprises: a stop plug (26) which can move between an open position and a position in which a first section of the hole (21) is sealed; a stop valve (28) which can move between an open position and a position in which a second section of the hole (21) is sealed; and means (22, 23, 27) for triggering both the movement of the stop plug (26) and the movement of the valve (28) from the open position to the sealing position in response to an overpressure (P2) in the hole (21). The invention is particularly suitable for self-contained equipment used to supply electrical power by means of a fuel cell.

  • Patent number: 7982069
    Abstract: A solvent that reversibly converts from a nonionic liquid mixture to an ionic liquid upon contact with a selected trigger, e.g., contact with CO2, is described. In preferred embodiments, the ionic solvent is readily converted back to the nonionic liquid mixture. The nonionic liquid mixture includes an amidine or guanidine or both, and water, alcohol, or a combination thereof. Single component amine solvents that reversibly convert between ionic and non-ionic states are also described. Some embodiments require increased pressure to convert; others convert at 1 atmosphere.

  • Patent number: 7980274
    Abstract: A dobby includes two controlled latches for coupling a drive element mounted to a main drive shaft of the dobby and an actuator element in rotation. A first resilient element resiliently biases each of the latches towards a configuration in which their respective bearing surfaces are engaged with corresponding surfaces of the actuator element. Control members are provided for moving the latches against the action of the first resilient element and that act directly on the first latch and indirectly on the second latch so as to move the first latch against the first resilient element to thereby disengage its bearing surface with a corresponding surface of the actuator element while the second latch remains in a configuration in which its bearing surface is engaged with another corresponding surface of the actuator element.

  • Patent number: 7959360
    Abstract: An antifriction bearing of the roller type for a pulling system of weaving loom including two end plates secured to the inner race and positioned respectively and axially close to each flank of the rollers, end plates lying radially beyond the raceways and the end plates and the inner race being intended to be mounted between two lateral flanges. At least one end plate has a shape defining at least one cavity adjoining all or part of a flank of the rollers and able to accept a lubricant. The inner race has two lateral shoulders each one defining an axial bearing surface for each flange, and a width of the inner race with its lateral shoulders is substantially equal to a distance separating the outermost axial faces of the end plates.

  • Patent number: 7958594
    Abstract: A vacuum cleaning system for use in a structure. System has receiver adapted to receive communication that an appliance has been activated, and a control circuit adapted to control the central vacuum cleaning system upon receipt of a communication at the receiver that the appliance has been activated. Example appliances include doorbell, telephone or ERV. System may have a communication module that communicates with corresponding appliance communication module. The system communication module may transmit communications to the appliance communication module. Alternatively, the appliance communication module may transmit communications to the system communications module. The modules may both receive and transmit. Preferably, communications between modules are radio frequency (RF) wireless, however wired communications, where wiring is possible or available, are also suitable.

  • Patent number: 7938456
    Abstract: A quick connect and quick release coupling for connecting two pipes, including a male element and a female element that are axially fitted and interlocked one inside the other and wherein a locking mechanism retains the male element in a coupled position and a temporarily retaining mechanism immobilizes the male element, after its release by the locking mechanism, in a position for flushing a pipe connected to the male element. The locking mechanism is controlled by a sleeve that slides relative to a body of the female element. When the temporarily retaining mechanism retains the male element in flushing position, it is subjected to a first force (E1) derived from a pressure (P) of the fluid flowing (F) from the male element outwards and to a second force (E2), opposite to the first, exerted by elastic return means which, when the pressure (P) drops to a safety threshold, moves the temporarily retaining mechanism into a position for releasing the male element from the female element.
