Abstract: Apparatus for the treatment of organic waste streams (1) is disclosed, in which the organic waste stream (1) is treated in order to reduce the average particle size (38) prior to entry into a biological reactor (40). The use of a mechanical device (38) to reduce this average particle size while simultaneously mixing the organic waste stream increases the efficiency of the biological reactor (40). The mechanical device (38) is preferably one which causes attrition and reduction in the average particle size of the organic waste stream (1). This results in a lower viscosity feed to the biological reactor (40), and therefore a far more efficient process, which can therefore handle a feed stream (1) of greater concentration than was previously thought to be possible.

Patent CA-2814286-A1 (CA)
Inventor: POWELL RONALD JOSEPH
IPC: E21B43/26
Filed: 2013-04-25
Abstract: A method of reducing the cost and environmental impact of chemicals used in hydraulic fracturing is to use multiple chemicals that are pre-mixed and then formed into a single solid blended mixture. By forming at least two chemicals into a single solid mixture, the complexity involved in transporting multiple solid or liquid chemicals is avoided. If the solid chemicals were merely premixed they would tend to segregate during shipping, handling, and storage altering the concentration of the chemical mix as it is pumped downhole.  Simply having less equipment on the wellsite increases the accuracy of the well treating process and decreases the likelihood of a time consuming and thus costly delay due to equipment failure.

Abstract: An electrical submersible pumping (ESP) system for use in a wellbore that can be assembled in the wellbore. Upper and lower pump tandems are fitted with connectors that align the tandems when coupled in the wellbore. The connectors on the lower tandems have bores with enlarged openings on upward facing surfaces. Downward pointing pins are on lower facing surfaces of the connectors on the upper tandems. The cross sectional area of each bore decreases with distance away from the openings, so that as the pins insert into the bores the pins move along a helical path that in turn rotates the upper tandem into a designated azimuth and into alignment with the lower tandem. Properly aligning the upper and lower tandems couples respective drive and driven shafts in the tandems as the upper tandem lands on the lower tandem.

Abstract: Embodiments of task-based, decreasing-price markets enable dynamic discounting of items for sale. In one example, users shop for products (e.g., clothing, electronics, or cars) or services (e.g., hotel rooms, plane tickets, or car rentals) using a computing device or mobile device. As the users shop, they view advertisements or perform other tasks, like answering questions, and the system discounts an item's price based on the number or complexity of the performed tasks. Each user who performs a task gets a chance to buy the item at its discounted price. The other users also get a chance to buy the item at the discounted price. If someone buys the item, the item's price returns to its starting value. If nobody buys the item, the system discounts the item's price further as the users perform more tasks until someone buys the item or the item's price reaches a minimum value.
