20110090762 | Underwater navigation system - The present invention provides an underwater navigation system which can determine the bearing and the range of a remotely located beacon from a navigation station. The remotely located beacon transmits a pair of signals each having a different propagation velocity. Typically, the pair of signals are an acoustic signal and an electromagnetic signal. The range of the beacon to the navigation station is determined by a time differential in the detection of the two signals at the navigation station. The time differential is alternately a variation in phase between the two signals, or a time difference between the reception of a timing event encoded in synchronization on the pair of signals. In one form, the navigation station is a mobile unit which navigates to the remotely located beacon, and in another form the navigation station has a fixed position, and the remotely located beacon is mobile. | 04-21-2011 |
20110133726 | Precision alignment system - The present invention provides a precision alignment system operable to provide alignment of a first and second apparatus. The precision alignment system makes use of inductive coupling between loop antennas in the first and second apparatus. The mechanism for alignment is the detection of a null in the signal induced in the loop antennas of the second apparatus arising from an input signal fed to a loop antenna of the first apparatus. The precision alignment system can be incorporated in a system for the wireless transfer of electrical power or may be incorporated in a system for the transfer of data. The precision alignment system of the present invention is particularly suited to applications where optical or other means for alignment of two apparatus are unreliable. In particular, the alignment system disclosed is suitable for operation underwater. | 06-09-2011 |
20110287712 | System for wireless communications through sea vessel hull - The present invention discloses a system for wireless communications and/or data transfer through a sea-vessel hull by means of electric and/or magnetic coupling between first and second transducers located on opposing sides of the hull. Transmit and receive transducers located on opposing sides of the hull are clamped around cables which penetrate the hull and which are fed through pressure hull glands in the hull. The inductive transducers couple electric and/or magnetic signals through the sea vessel hull via paths through the pressure hull glands or via paths through the cables. The system for wireless communication and/or data transfer of the present invention is capable of operation through an electrically conductive sea vessel hull which would ordinarily present a physical barrier against the transmission of such signals. The system can be deployed on an ad ad-hoc basis and is capable of providing high data rate and high bandwidth communications and/or data transfer through the sea vessel hull. The system does not interfere with existing cabled systems penetrating the hull via the pressure hull glands. In particular, the system of the present invention requires no modification of existing hardware nor does it require any modification of the hull for operation. | 11-24-2011 |

20140246357 | SEPARATION OF SOLID ASPHALTENES FROM HEAVY LIQUID HYDROCARBONS USING NOVEL APPARATUS AND PROCESS ("IAS") - An apparatus and process is provided for improved asphaltene separation from heavy hydrocarbon or bitumen with low process complexity through mass transfer using solvent and counter-current flows, with three sections: an upper DAO/solid-asphaltene separation zone, a middle solvent mixing and segregation zone, and a bottom clarification zone. Solvent mixed with heavy hydrocarbon forms a process feed introduced to the process vessel's upper zone and exposed to counter-current solvent removing DAO from solid asphaltene particles in the feed, the particles fall through the middle zone and are mixed with introduced solvent, which introduced solvent segregates DAO-rich solution in the upper zone (for extraction from that zone) from solvent-rich mixtures in the middle mixing and lower clarification zones. Solvent flows and precipitate movement are controlled to optimize mass transfer in process, resulting in high DAO recovery and dry, solid asphaltene product. | 09-04-2014 |
20150361348 | SOLVENT DE-ASPHALTING WITH CYCLONIC SEPARATION - The present invention relates to a method of improving a heavy hydrocarbon, such as bitumen, to a lighter more fluid product and, more specifically, to a final hydrocarbon product that is refinery-ready and meets pipeline transport criteria without the addition of diluent. A solid asphaltene by-product is created for easy handling and further processing. The invention is targeted to enhance Canadian bitumen, but has general application in improving any heavy hydrocarbon. | 12-17-2015 |
20160040079 | ENHANCED METHODS FOR SOLVENT DEASPHALTING OF HYDROCARBONS - Improvements to open-art Solvent Deasphalting (SDA) processes have been developed to reduce capital and operating costs for processing hydrocarbon streams are provided whereby open art SDA scheme is modified to include appropriately placed mixing-enabled precipitators (MEP's) to reduce solvent use requirements in an asphaltene separation step and to increase overall reliability for SDA processes, particularly suitable for Canadian Bitumen. When integrated with a mild thermal cracker, the improved SDA configuration further improves crude yield to be pipeline-ready without additional diluent and for use to debottleneck existing facilities such as residue hydrocrackers and coking units. | 02-11-2016 |
20160046879 | LOW COMPLEXITY, HIGH YIELD CONVERSION OF HEAVY HYDROCARBONS - A process for producing pipeline-ready or refinery-ready feedstock from heavy hydrocarbons using a high-performance solvent extraction process with high local solvent-to-process fluid ratios yet maintaining low overall solvent-to-process fluid ratios, by first performing mild thermal cracking on the heavy hydrocarbons and then separating asphaltene-rich fractions from a resulting thermally affected fluid so that the high solvent-to-oil ratio portion of the process acts only on those asphaltene-rich fractions, and producing a dry, solid asphaltene as an end-product. | 02-18-2016 |

20130341338 | INSULATED CONTAINER WITH WORK SURFACE - A soft sided insulated container assembly includes a first portion having an insulated, soft sided external wall structure, and a second portion that defined a lid co-operable with the first portion. The lid includes an auxiliary access opening and closure member that are smaller than the main opening, and that can be operated one-handed. A rigid work surface is provided, typically immediately adjacent to the secondary closure member, the work surface providing a place for holding or mixing a drink or for preparing a snack. In some embodiments the work surface may be movable relative to the container, whether slidable in a co-planar or parallel planar manner in translation, or folding as in a foldable shelf. The entire container assembly may be foldable or collapsible to a storage condition, and the rigid member, whether fixed or movable, does not impede that folding or collapsing. | 12-26-2013 |

20160101924 | SOFT-SIDED INSULATED CONTAINER WITH LID FITTING - A soft-sided insulated container assembly has a generally box-shaped form like a school lunch box, having a main body and a lid. The lid is formed of one of the largest panels of the box-structure, and is joined to the main body of the box by a hinge that lets the lid lie flat next to the main body when the box is open. The inside face of the lid then defines a work surface on which to place objects such as foodstuffs and beverages. The work surface may be formed in a substantially rigid molded stiffener member, and may be divided into sub-regions with raised retainers to discourage sliding of objects where not precisely level. The container assembly may include a rigid internal liner with which the lid may mate zipperlessly. The mating portion of the lid may be formed in the same rigid member as the work surface. | 04-14-2016 |
