摘要:
A fluid transport apparatus maintains temperature of a fluid transported through a conduit. The fluid transport apparatus includes a fluid transport conduit that is selectively deformed by a pressure within a compressor conduit and allowed to return to its original shape by venting the pressure through a venting valve. The alternating pressurization and release of pressure from the compressor conduit moves fluid through the fluid transport conduit. A thermal conductor is associated with the fluid transport conduit to maintain the temperature of the fluid in the fluid transport conduit within a predetermined range.

A highwall mining borehole backfill composition utilizing waste glass and fly ash can be used as a backfill utilizing waste products that would normally have to be landfilled. The composition is a cost effective mixture of cement, fly ash, glass and water and may incorporate additional fine and coarse aggregates as well as chemical admixtures. Fly ash takes the place of some or all of the fine aggregate, and cullet takes the place of coarse aggregate in a mixture of concrete. Use of the backfill supports the overlying strata so as to eliminate or reduce the need for barrier pillars.

The relative combustion phasing of a homogenous charge compression ignition engine is controlled by controlling the introduction of ions and free radicals to cylinders in the engine. The engine has an engine housing with at least a first and second cylinder and an intake system that introduces a combustible mixture of air and fuel to the cylinders. A piston is disposed in each of the cylinders and is operable to compress a combustible mixture until the mixture auto ignites, without the introduction of a spark.

An internal combustion barrel engine includes an engine housing and an elongated power shaft. A combustion cylinder and a guide cylinder are spaced apart and disposed on a common cylinder axis. A double-ended piston includes a combustion end disposed in the combustion cylinder so as to define a combustion chamber between the combustion end and the closed end of the combustion cylinder. A guide end is disposed in the guide cylinder. Combustion occurs only in the combustion cylinder and does not occur in the guide cylinder.

A method and device for reducing positron emitter isotope labeled CO2 to positron emitter isotope labeled CO generally includes introducing a volume of positron emitter isotope labeled CO2 into a first heated reaction vessel comprising a metal oxide, such as Iron (II) Oxide such that the CO2 is reduced to CO upon contact with the Iron (II) Oxide. The volume is then transferred to a second reaction vessel to remove any un-reacted CO2, preferably, via a soda-lime trap. The volume is then transferred to a target, e.g., a storage vessel or subject. The CO2 includes one of [11C] or [15O]. The first reaction vessel is, preferably, heated to a temperature of between 900 and 1000° C., and more preferably, to between 925 and 975° C., and even more preferably, to approximately 950° C. Preferably, the Iron (II) Oxide powdered and has a particle size of about −10 mesh.

The present disclosure describes embodiments of a power-over-ethernet (“POE”) controller and an access control system comprising the same. In an embodiment, the access control system includes a POE controller configured to couple with a Fire Access Control Panel of an automated Fire Detection System. The access control system may further include one or more peripheral devices coupled with the POE controller and configured to be powered with electrical power received via an ethernet port of the POE controller. The peripheral devices may include an access device, a door strike, and a digital output device. Embodiments of a kit containing one or more partially or fully assembled components of the access control system are also described.

A fluid transport apparatus maintains temperature of a fluid transported through a conduit. The fluid transport apparatus includes a fluid transport conduit for transporting fluid, the fluid transport conduit having an inlet end that is coupled to a fluid supply and an outlet end that is coupled to a receiving port, a compressor conduit configured to pump fluid through the fluid transport conduit by pressurizing and venting the compressor conduit, and a thermal conductor configured to achieve a non-ambient temperature for the fluid within the fluid transport conduit as the compressor conduit is operated to move the fluid through the fluid transport conduit.

摘要:
An underwater cable deployment system includes a series of cables, pre-wound on a set of reels, disposed upon a pallet and connected to a distribution hub on the pallet. The pallet is lowered to the ocean floor and a remotely operated vehicle (ROV) is also lowered to the ocean floor to deploy cables to form a predetermined array on the ocean floor. Preferably, the pallet is delivered to the ocean floor in advance by crane with the reel-mounted sensor array cables being deployed later by ROV. Optionally, the ROV may include a jetting package configured to bury the sensor cable as it is being deployed from the reel on the ROV.
