  • Publication number: 20160172990
    Abstract: A power converter includes first and second DC terminals between which the power converter is operable to generate a voltage difference. The power converter also includes a control unit that is configured to operate in a normal mode during normal operation of the power converter and in a fault mode when a fault occurs in a respective DC power transmission medium that is operatively connected in use to one of the first or second DC terminals. The control unit in the normal mode generates a normal operating voltage difference between the first and second DC terminals. The control unit in the fault mode generates a modified operating voltage difference between the first and second DC terminals while maintaining the respective voltage potential with respect to earth of the other of the first and second DC terminals. The modified operating voltage difference is lower than the normal operating voltage difference.

  • Publication number: 20160166795
    Abstract: The resuscitation method and device incorporates a T-piece and/or bag and mask resuscitation device that transforms into short term (and then long term) CPAP device. This results in continuum of respiratory care in the Delivery Room, and potentially in the nursery. The respiratory support is uninterrupted. The device can include a modular design, which adds heat and humidity in a modular way, when the long term CPAP requires it. The resuscitation device and method includes a PIP phase and a PEEP phase. This is driven either manually or by a finger and gas power. The exhalation phase is PEEP, where the PEEP is a small positive pressure to ensure the lungs remain open. When the baby is spontaneously breathing, meaning no longer in need of PIP, the PEEP can be adjusted to be continuous positive pressure, or CPAP. If the CPAP is short term, there is minimal need for heating or humidifying the air. When the CPAP is used longer term, a heater and humidifier can be applied to the air source of the CPAP.

  • Patent number: 9365784
    Abstract: A coal gasifier is retrofitted to achieve multiple advantages such as reduced oxygen consumption, reduced CO2 and NOx emissions, better H:C ratio, better carbon conversion etc. This is achieved by dividing the coal into at least two zones and modifying the gasifier and operating it as described. The coal is injected into a first zone, configured to devolatilize a substantial portion of the injected coal to produce coal char and volatiles. The operation is tuned to substantially consume the oxidant injected in the first zone. A low-calorific-value, high oxidant feedstock is injected in second zone of the gasifier. The devolatilization of the low-calorific-value, high oxidant content feedstock provides the oxygen containing compounds which gasify at least a portion of the coal char generated in the first zone.

  • Patent number: 9366851
    Abstract: Methods and apparatus are described for delivering index-matching immersion liquid in high numerical-aperture optical microscopy and lithography. An array of immersion liquid droplets is delivered to a specimen substrate or specimen substrate cover by an immersion liquid printing apparatus. An immersion liquid reservoir provides immersion liquid to the printer by a precision pump. The printer delivers immersion liquid to the substrate or substrate cover in arrays of immersion liquid droplets of defined volumes and array patterns. The volumes and patterns of array droplets delivered to the substrate or substrate cover are optimized to maintain adequate immersion liquid between the substrate or substrate cover and an immersion objective while avoiding the formation of air bubbles in the immersion liquid and the accumulation of excess volumes of immersion liquid.
