摘要:
A tobacco smoking device comprises a porous mass of active particles adapted to enhance a tobacco smoke flowing over said active particles and binder particles. The active particles comprises about 1-99% weight of the porous mass, and the binder particles comprises about 1-99% weight of said porous mass. The active particles and said binder particles are bound together at randomly distributed points throughout the porous mass. The active particles have a greater particle size than the binder particles.

摘要:
A polyethylene powder has a molecular weight in the range of about 300,000 g/mol to about 2,000,000 g/mol as determined by ASTM-D 4020, an average particle size, D50, between about 300 and about 1500 μm, and a bulk density between about 0.25 and about 0.5 g/ml. On sintering, the polyethylene powder produces a porous article having a porosity of at least 45% and a pressure drop less than 5 mbar. The porous article is useful in, for example, wastewater aeration and capillary and filtration applications.

摘要:
A method includes receiving a direct current (DC) signal at an inverter control system from a bus. The inverter control system includes an inverter and an inverter controller. The received DC signal is compared to a reference value. Based at least in part on the comparison, the inverter controller determines whether to adjust a magnitude of the DC signal received through the bus. The DC signal is converted to an alternating current (AC) signal with the inverter, and the AC signal is provided to a load.

In one example embodiment, the method includes receiving an X.25 packet at a LAN interface of a network device. Further, the method includes determining whether a local CUG value is associated with the X.25 packet. The local CUG value may be replaced with a network CUG value associated with the X.25 packet. Thereafter, the X.25 packet, and the associated network CUG value, may be formatted to generate an IP packet. The formatting may include the use of at least one formatting regime including encapsulating the X.25 packet, that includes the associated network CUG value, in an XOT, or using protocol translation to translate the X.25 packet that includes the network CUG value into an equivalent IP packet. The method includes transmitting the IP packet using a WAN interface card, the WAN interface card including a primary interface, and at least one backup interface.
摘要:
A method of providing electrical power using a split bus configuration includes receiving a first direct current at a positive bus of a split bus, where the first direct current originates from a first fuel cell segment. A second direct current is received at a negative bus of the split bus, where the second direct current originates from a second fuel cell segment. A third direct current is also received at the split bus such that a combined direct current is formed including the first direct current, the second direct current, and the third direct current. The third direct current originates from an alternative direct current (DC) source. The combined direct current is provided to an inverter such that an alternating current is generated for a load.
