Patent CA-2678213-C (CA)
Inventor: SEDERQUIST RICHARD ALLAN
IPC: C10J1/20
Filed: 2008-02-19
Granted: 2010-09-21
Abstract: A method of operating a syngas generator within a desired temperature range, despite a need for intermittent syngas output, involves switching between operating the syngas generator in a rich mode and a lean mode. Operation of the syngas generator in both the rich mode and the lean mode sustains the operating temperature of the syngas generator within that desired temperature range, particularly for non-catalytic reactors. The method of switching from the lean mode to the rich mode of operation can include decreasing the oxygen-to-carbon ratio of reactants supplied to the syngas generator. The flow rate of one or more of the reactant streams supplied to the syngas generator can be actively controlled in order to switch operation of the syngas generator between the rich and lean modes.

Abstract: A sensor used to determine the height of one or more fluids in a fluid column and to determine a location of an interface or boundary between a plurality of fluids in a fluid column is disclosed. The sensor includes a plurality of sensing elements comprising a capacitor and other components, such as resistors and inductors. The sensor also includes an oscillator that alters a frequency of an electrical current applied to the sensor, from which the dielectric constant of the fluid in which each sensing element is disposed can be determined. Methods of using such a sensor to determine the relative heights of various fluids in a fluid column are disclosed. In particular, methods of using embodiments of the invention in a well, such as water and petroleum wells, are described.

Abstract: A V-ribbed belt 10 includes a bottom rubber layer 12, an adhesive rubber layer 16, and a fabric 22. The bottom rubber layer 12 includes short fibers 14, a part of which protrude from the friction surface 12S of the bottom rubber layer 12. In the bottom rubber layer 12, an FEF carbon black with an average nitrogen adsorption surface area (ASTM D1765-01) of below 49 (m2/g), is used as a reinforcement. Therefore, the friction surface 12S of the bottom rubber layer 12 is slightly uneven, thus preventing the generation of an abnormal noise under usage of the V-ribbed belt 10. Further, after the short fibers 14 protruding from the friction surface 12S of the bottom rubber layer 12 have worn down, the unevenness of the friction surface 12S can be properly maintained by using such a carbon black, so that abnormal noise can be prevented.

Abstract: A method is disclosed for producing an intermediary product in the form of a nut-based pellet that is capable of being stored for up to about six months. To form the nut pellets, a nut dough is passed through an extruder. The extrudate produced is then cut into pellets and dried. Starch pellets can then optionally be mixed with the nut pellets or small nut pieces and cooked to form a snack chip. The snack chip is formed by compressing and cooking the pellet mixture, expanding the pellet mixture, and compressing the pellet mixture again.

IPC: A21D8/04

Granted: 2017-02-28
Abstract: Dough with a high sucrose content (such as cake dough) tends to inhibit the activity of an anti-staling amylase such as Novamyl®, making it less effective to prevent the staling of dough-based products with high sucrose content such as cakes. A good anti-staling effect in cakes can be achieved by using a carefully selected anti-staling amylase with certain properties. Analysis of a 3D  structure of Novamyl® shows that sucrose may inhibit by binding in the active site. Sucrose docks into the active site of Novamyl®  differently from the substrate or inhibitor in published models 1QHO and 1QHP.  This finding is used to design sucrose-tolerant variants.

Abstract: In one embodiment, a method for drilling a wellbore includes injecting drilling fluid into a top of a tubular string disposed in the wellbore at a first flow rate. The tubular string includes: a drill bit tubular joints connected together, a longitudinal bore therethrough, and a port through a wall thereof. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The cuttings and drilling fluid (returns) flow to the surface via an annulus defined between the tubular string and the wellbore. The method further includes rotating the drill bit while injecting the drilling fluid; remotely removing a plug from the port, thereby opening the port; and injecting drilling fluid into the port at a second flow rate while adding a tubular joint or stand of joints to the tubular string. The injection of drilling fluid is continuously maintained between drilling and adding the joint or stand to the drill string. The method further includes remotely installing a plug into the port. A clamp specially adapted to carry out this method is also disclosed.

Abstract: Aspects relate to determining whether a constraint or other condition on a mobile device may be alleviated or better satisfied by switching from one communication network to another for a call (or setting up a call on one network in preference to another). A mobile device is operable to conduct a communication session over at least two different communication media, which have different power consumption characteristics. Where a remaining battery power level is constrained, a determination can be made whether using one network over another saves more than a threshold amount of power over another network. Estimates of battery life for each network can be made based on predictions of a length of the communication session, and a power factor calculated for the network.
