摘要:
A multi-stage minimally invasive surgical procedure and associated instruments are disclosed. First, the surgical site is prepared. After preparation, the bone screws or anchors are attached to the bone. Subsequent to insertion of the screws, a rod or connecting member is positioned within the yoke portion of the bone screw. Caps are then placed in a pre-lock position within the yokes. The bone screws may be compressed together or distracted along the rod or connecting member, thereby setting the final spacing of the bones or bone segments. Finally the caps are moved to a final lock position to fix the screws to the rod or connecting member to maintain the bones in position relative to each other.

A process of regulating the water content of water-fluidized oil sand ore during processing of the ore is disclosed. The weight (mo) of a sample charge of oil sand ore having a bulk volume (Vt) is determined. The inter granular voids of the sample charge are then filled with water, and the weight (ma) of the added inter granular water is determined. A target specific gravity value (SGmix) is selected for the fluidized oil sand ore. The volume of additional water, ΔV, to add to a sample charge of bulk volume Vt, to achieve the target specific gravity value (SGmix) is calculated by solving the following equation: Δ V = V t · ( ( m o + m a ρ w · V t ) - SG mix SG mix - 1 ) + m a ρ w The determined volume ΔV of additional water per bulk volume Vt of oil sand ore to be processed is added to the oil sand ore, producing water-fluidized oil sand ore. The ore is then processed to concentrate the bitumen.

摘要:
Equipment and a process for separating bitumen from oil sand in a process stream are disclosed. The equipment includes several processing vessels and one or more local area radio frequency applicators to selectively heat the process stream in local areas of the equipment. The local area can be adjacent to an input or output of a component of the equipment. Also disclosed is equipment for processing an oil sand—water slurry, including a slurrying vessel, a slurry pipe, and a local area radio frequency applicator. The local area radio frequency applicator is located outside of the slurry pipe, and heats the local area without significantly heating the contents of the slurrying vessel or of the downstream portion of the slurry pipe.

A vacuum pick mechanism (100) for picking sheet media comprising control circuitry (126), a pump (110), a suction cup (106), a pick line (112) connecting the pump (110) to the suction cup (106), a pressure sensor (122) arranged to measure the pressure within the pick line (112) and a motor arranged to drive the pump, the control circuitry being arranged to receive the pressure measured by the pressure sensor and to control the motor to drive the pump such that a predetermined target pressure is measured by the pressure sensor.
摘要:
A method and apparatus for automatically manufacturing a computer. An order is received from a customer. A manufacturing plant assembles together the hardware and software components from stores specified by the order, and loads the software packages onto the computer. A Web page is provided for the customer to specify any software modifications required. Those modifications are recorded as auto-modification files. The auto-modification files and the order details are checked against each other and the manufacturer's current capabilities for consistency by a validation unit. Each auto-modification file in turn is called by the manufacturing control unit, which determines the configuration data corresponding thereto and enters that configuration data into the computer as the software packages are being loaded.

A method of polishing a substrate includes polishing a substrate with a generally linear polishing sheet, polishing the substrate with polishing pad composed of a napped poromeric material, and conditioning the polishing pad.
摘要:
A method and apparatus for sealing a puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being with an anchor, a sealing plug and a filament connecting the anchor and sealing plug. The method and apparatus provide for a tamping device that is coilable in some configurations and stiff and straight in other configurations. The coilable tamping device may also automatically tamp the sealing plug when the apparatus is withdrawn from the puncture site. The automatic uncoiling and tamping is facilitated by transducing a motive force generated by the withdrawal of the apparatus into a tamping force.
摘要:
A vertebral implant for insertion into a patient includes first and second end members that include recesses for engaging a spacer member and a distractor. The end plates include a bone contact surface and an oppositely facing surface. A peripheral surface extends around a perimeter of the end members. The recesses may extend inward from the oppositely facing surfaces. Further, the recesses may extend inward from the peripheral surfaces. The recesses for engaging the spacer member and distractor may be separate from each other or may intersect one another. A spacer may engage the end plates to establish a desired vertebral spacing. The spacer may be positioned between the implants after a desired distraction is obtained with a distractor that engages the end plates.
