Abstract: A trailer can include an open bed, a frame, an actuator, and a pin. The open bed can extend a width and a length. The frame can support the open bed. The actuator can be mounted on the frame. The pin can be mounted on the frame along a periphery of the open bed. The pin can be drivable by the actuator in reciprocating movement transverse to the length between a first pin end limit of travel defining a refracted position and a second pin end limit of travel defining an extended position. The pin can be recessed from the open bed when in the retracted position and extend above the open bed when in the extended position.

Abstract: A cascading processor is described which includes a processor body having an upper inlet and a lower outlet, such that materials pass by force of gravity from inlet to the outlet. The processor body has a plurality of processing levels which are sequentially vertically spaced progressively downwardly from the inlet to the outlet, such that materials cascade by force of gravity from one processing level to another processing level as the materials pass through the processor body front the inlet to the outlet. This cascading processor was developed for recovery of bitumen front oil sands, but can be used to process oil shales or to process biomasses.

Abstract: Particular embodiments comprise a non-dedicated, temporarily installed, airborne special mission payload mounting system which is mechanically interfaced to the Air Deployment System (ADS) rails of a host cargo aircraft. An Adaptive Mounting Plate (AMP) is placed over an ADS rail section and restrained in position. Once the AMP is secured, an articulated or fixed position strut can be attached to it through the opened side doorway without removing the original door. Once the fixed position or articulated strut is bolted to the AMP, a one piece or segmented two piece pressurized door plug indented along its lower periphery to accommodate the protruding form factor of the fixed position or articulated strut is installed within the vacant doorway above the strut providing an airtight seal and thereby permitting pressurization of the aircraft.

Abstract: The system and method is directed to improved separation or clarification of solids from a solids-laden liquid, including the removal of low gravity solids. A liquid to be treated is introduced into the inlet of a solid-liquid separator modified to include one or more sources of vibrational energy. The liquid is directed through a conduit within the separator. This conduit can be configured into a tortuous flow path to assist in the separation of solids from the liquid, the tortuous path being interconnected between two separation towers. Vibrational energy and gas sparging is applied to the flow path. As solids fall out of solution, they are collected. The clarified liquid is also collected. A vacuum can be applied to the system to assist in moving the solid-liquid mixture through the system and to provide vacuum clarification. Electrocoagulation electrodes can also be employed.

Abstract: A method of upgrading heavy oil in which the heavy oil is preheated to above a boiling point of water to remove water as steam and lighter fractions as vapors. The heavy oil passes downwardly through a series of sequential horizontal heat gradients in a temperature gradient reactor. A temperature of each sequential heat gradient progressively increases so that lighter fractions of the heavy oil vaporize with minimal cracking and heavier heavy oil fractions continue to fall by force of gravity downwards. As they pass through further sequential heat gradients of progressively increasing temperature, they tend to crack into lighter fractions in the presence of nascent hydrogen. Coke, formed from heavier heavy oil fractions generated and deposited on a fluidized catalytic bed a bottom of the temperature gradient reactor, is fluidized with superheated steam. The superheated steam generates the nascent hydrogen required to promote hydrogen reactions by indirect heated steam reforming and water-gas shift reactions.

Abstract: A slide blind controls flow through conduits at a flanged connection. The slide blind has a right and left working plates configured such that one of the working plates is sealed between the flanges a perimeter thereof adjacent to inner sides of the flange bolts. A joiner member connects the right and left working plates, and handle members extend in right and left directions from the corresponding working plates. The joiner and handle members have a thickness less than the thickness of the right and left working plates. The handle members and the joiner member define first and second sets of bolt holes to fasten the slide blind with either the right or left working plate between the flanges. The joiner and handle members are significantly lighter weight than the working plates, and can be removed for convenient transport.

Abstract: A method for producing liquid natural gas (LNG) includes the following steps. Compressor stations forming part of existing natural-gas distribution network are identified. Compressor stations that are geographically suited for localized distribution of LNG are selected. Natural gas flowing through the selected compressor stations is diverted to provide a high pressure first natural gas stream and a high pressure second natural gas stream. A pressure of the first natural gas stream is lowered to produce cold temperatures through pressure let-down gas expansion and then the first natural gas stream is consumed as a fuel gas for an engine driving a compressor at the compressor station. The second natural gas stream is first cooled with the cold temperatures generated by the first natural gas stream, and then expanded to a lower pressure, thus producing LNG.
