An expandable and compressible carport is provided. The carport includes vertical supports adjustable in height and trusses adjustable in width. A first vertical support is adjustable in height by way of an inner tube telescoping with an outer tube. A first truss is coupled to a top end of the first vertical support and includes an adjustable width by way of an inner tube telescoping with an outer tube. The present invention further includes a second vertical support that is adjustable in height by way of an inner tube telescoping with an outer tube. A second truss is coupled to a top end of the second vertical support and includes an adjustable width by way of an inner tube telescoping with an outer tube. A ridge board connects the first truss and the second truss together.

An inline bitumen froth steam heater system including steam injection and static mixing devices is provided. The system heats and de-aerates input bitumen froth without creating downstream processing problems with the bitumen froth such as emulsification or live steam entrainment. The system is a multistage unit that injects and thoroughly mixes steam with bitumen resulting in output bitumen material having temperature of about 190° F. The system conditions a superheated steam supply to obtain saturated steam at about 300° F. The saturated steam is contacted with bitumen froth flow and mixed in a static mixer stage. The static mixers provide surface area and rotating action that allows the injected steam to condense and transfer its heat to the bitumen froth. The mixing action and increase in temperature of the bitumen froth results in reduction in bitumen viscosity and allows the release of entrapped air from the bitumen froth.

An apparatus for processing bitumen froth comprising a cyclone body having an elongated conical inner surface defining a cyclone cavity extending from an upper inlet region with a diameter DC to a lower apex outlet with a diameter DU of not less than about 40 mm; an inlet means forming an inlet channel extending into the upper inlet region of said cyclone cavity; and a vortex finder forming an overflow outlet of a diameter DO extending into the upper inlet region of said cyclone cavity toward said lower apex outlet and having a lower end extending an excursion distance below said inlet channel, said excursion distance being operable to permit a portion of bitumen that passes through said inlet channel to exit said overflow outlet without having to make a spiral journey down said cyclone cavity, wherein a lower end of the vortex finder within the cyclone cavity is disposed a free vortex height (FVH) distance from said lower apex outlet.

Discloses apparatus to perform a process to remove water and minerals from a bitumen froth output of a oil sands hot water extraction process. A bitumen froth feed stream is diluted with a solvent and supplied to a primary inclined plate separator stage, which separates the bitumen into an overflow stream providing a bitumen product output from the circuit and a bitumen depleted underflow stream. A primary cyclone stage, a secondary inclined plate separator stage and a secondary cyclone stage further process the underflow stream to produce a secondary bitumen recovery product stream and a recycle stream. The secondary bitumen recovery product steam is incorporated into and becomes part of the circuit bitumen product output stream. The recycle stream is incorporated into the bitumen froth feed stream for reprocessing by the circuit.

A computer implemented method is provided for extracting hierarchical data from one or more tables in a database, the method comprises firstly receiving user input identifying, one or more tables in the database that contain the hierarchical data and the hierarchical structure of the hierarchical data. A Structured Query Language (SQL) statement is then generated using the user input received. The SQL statement is presented to the database for execution and the hierarchical data are then extracted from the database in response to the execution of the SQL statement.

The present invention discloses a lamphead having a multi-positional base and removably mountable reflector flashtube assembly. The lamphead base is configured to detachably mount to a flashtube assembly such that the flashtube assembly may be interchanged with a second flashtube assembly. The flashtube assembly defines an opening and an inner chamber having a reflective surface. A flashtube is mounted within the inner chamber between the reflective surface and the opening, wherein the reflective surface extends behind the flashtube, thereby increasing the intensity of the light emitted thereby. The lamphead base may be adapted for pivotable mounting on a stand to a full vertical position without interfering with the stand. In addition, the lamphead base may include a rear surface defining one or more holes and a support structure extending rearward from the hole(s), the support structure being capable of supporting the lamp base on a substantially planar surface such that when so supported the hole is spaced from the supporting surface so that the fan may circulate air through the hole for cooling the lamphead.
