Patent CA-2581586-A1 (CA)
Inventor: OZUM BAKI
IPC: E21B43/16
Filed: 2007-03-14
Abstract: In a method for enhancing the efficiency of bitumen recovery from oil sands ore, CaO lime (or Ca(OH)2) is mixed into an oil sands ore-water slurry prior to or during the operation of slurry-based bitumen extraction processes. The lime is introduced at dosages effective to reduce the electro-chemical attraction between clay particles and bitumen in the slurry, thereby promoting detachment of clay particles from bitumen droplets in the ore-wate r slurry. This occurs because water-soluble asphaltic acids formed at the bitumen-water interface act as surfactants and eliminate the activity of Ca2+ and Mg2+ ions binding the cla y particles and bitumen together. The detachment of clay particles promotes the attachment o f air bubbles to the bitumen droplets, thereby forming a bitumen-rich froth which will float to t he surface of the ore--water slurry, thus facilitating bitumen recovery.

Abstract: Dice in dice games are capable of being tossed or rolled to reveal variations of values, to use in adherence to specific dice-game--rules, with many objectives In each of any given game. There are many arrangements of values to attain, in each of any game that uses a die or combination of dice. This Dice-Toy-Game has en-cased-dice in rotating-dice-chambers, suspended by a support-rod, that is situated through each of a series of support-base-columns, by means of access-holes, giving the purpose of even distribution of weight and proper spacing. When the rotating-dice-chambers are caused by a player to spin, the chambers will rotate on the support--rod and upon stopping, will reveal a value on the dice inside the rotating -dice-chamber cavity. The couinterweight constructed in the lower-rotating-dice-chamber will cause the chamber to continually stop, with the dice in view through the transparent semi- shere-like-dome, cavity side upward. Values are then collected by using the values on the top-most side of the dice. These values can then be applied accordingly, to the values in the game-rules of any game being played.

Abstract: This invention relates to the culture of dendritic cells from human embryonic stem (ES) cells. Human ES cells are first cultured into hematopoietic cells by co-culture with stromal cells. The cells now differentiated into the hematopoietic lineage are then cultured with GM-CSF to create a culture of myeloid precursor cells. Culture of the myeloid precursor cells with the cytokines GM-CSF and IL-4 causes functional dendritic cells to be generated. The dendritic cells have a unique phenotype, as indicated by their combination of cell surface markers.

Abstract: The invention provides a method and system having a computer system and imaging sensors that capture image data of an object, such as a carcass, as it moves through a processing facility and is converted into individual food products.  The computer system analyzes the image data to produce a blob for the object being monitored. Source information that is referenced with the object being monitored can be associated with the object's blob. The blob can be used to track and identify the object, and to determine when one or more additional objects have been converted from the object being monitored. The computer system can create blobs for the additional objects and associate the referenced information with the new blobs. In one embodiment, the computer system is capable of continuously associating the source information for a particular source unit of food with converted food products that are converted from the source unit.

Abstract: The invention relates to a method for manufacturing a board tray (7), to a tray blank feasible for the method, and to a tray obtained by the method. The method comprises moulding a blank of plastic-coated board into the tray (7) comprising a bottom (3), side walls (4), as well as a rim flange (5), the blank being compressed in a direction transverse to the tray's side walls and rim flange. According to the invention, the blank is made thinner on its side opposite to the plastic coating such that, during , the moulding process, the plastic coating double-folds at the compressed parts and stabilizes compressions (8) by becoming sealed to itself. Making the blank thinner is most conveniently effected by carving the board layer with a laser beam for having the fiber material predominantly or completely removed from where the cuts are located. As a result of the moulding process, the tray's rim flange (5) develops a smooth plastic surface which enables closing the tray hermetically with a heat-sealed cover.
