Patent CA-2970003-C (CA)
Inventor: HARTCHER PAUL
IPC: E21C41/28
Filed: 2015-10-01
Granted: 2022-08-30
Abstract: Embodiments of this invention relate to highwall mining, and more particularly to a launch vehicle adapted for use in highwall mining of downward angled seams of mineable material, such as coal. More specifically, the provided launch vehicle includes a lower deck, an upper deck disposed above the lower deck, a launch deck pivotally attached to the upper deck, a first conveyor belt carried on the lower deck and a second conveyor belt carried on the launch deck. A conveyor car is positioned on the launch deck while the launch deck is in a substantially horizontal orientation, then the launch deck is tilted in a vertical place relative to the upper deck to substantially match a dip angle of the seam to be mined. The conveyor car is attached to a conveyor train extending into the seam as the rearmost car in the train. As the conveyor train advances into the seam, the launch deck is returned to a horizontal orientation, an additional conveyor car is added to the launch deck, and the launch deck is again tilted to substantially match the dip angle of the seam to add the additional conveyor car as the new rearmost car in the conveyor train.

Title: Hydraulic valve cover assembly
Inventor: DEEL STEVEN K
IPC: E21B21/10
Filed: 2016-06-13
Granted: 2019-07-02
Abstract: The systems, devices, and methods described herein describe a valve cover assembly that enables the easy removal and insertion of a screw gland into a threaded ring. The valve cover assembly includes an outside housing that provides an offset between a fluid end module and a top end of the valve cover assembly. A spring is positioned between the top end and the threaded ring and biased to provide a downward force on the threaded ring. The screw gland applies a reaction force against a valve plug. A piston is positioned at a base of the threaded ring in contact with the fluid end module. When actuated, the piston overcomes the downward force and lifts the threaded ring from the fluid end module. This reduces the force on the plug and allows a user to remove the screw gland by hand (and install as well) and without additional machinery required.

Title: Waterwheel
Inventor: CARRUTHERS PENELOPE JANE
IPC: F03B7/00
Filed: 2017-06-20
Granted: 2023-08-01
Abstract: A breastshot waterwheel is configured to extract energy from an incoming water flow. The waterwheel is rotatable about an axis and comprises a plurality of paddles, each of the said paddles being in communication with the incoming water flow for a respective water receiving portion of a rotation cycle of the waterwheel about the axis. During the water receiving portion of the rotation cycle for a said paddle, the incoming water flow flows onto a water receiving surface of the paddle. The water receiving surface extends between first and second ends of the paddle. The first end is upstream of the second end and is configured such that, during at least a portion of said water receiving portion of the rotation cycle for said paddle, the incoming water flow flows in a substantially horizontal direction across said first end of the paddle onto an upstream portion of the water receiving surface. At least a portion of the incoming water flow received by the upstream portion of the water receiving surface flows from the upstream portion onto a downstream portion of said water receiving surface, thereby changing direction and exerting a force on the paddle causing the waterwheel to rotate about the said axis in a rotational direction. The waterwheel is configured to rotate about said axis in said rotational direction such that a magnitude of a tangential velocity of the first end of the said paddle is less than a speed of the incoming water flow flowing across the said first end of the paddle during the water receiving portion of the rotation cycle for the said paddle.

Title: Steam-generating unit of dual circuit reactor with purge and drain system
Inventor: DOROKHIN KONSTANTIN VLADIMIROVICH
IPC: F22B37/52
Filed: 2017-12-29
Granted: 2023-10-03
Abstract: The proposed double-loop nuclear reactor steam generating plant having a blowdown and drainage system is implemented on the basis of a closed loop without the conventional blowdown tanks and is designed for maximum pressure of the working fluid in the steam generators. Steam generator blowdown water is brought together into a single line, cooled in a regenerative heat exchanger then in a blowdown and drainage aftercooler, and removed from the containment building. Outside the containment building, the steam generator blowdown water is fed for treatment into a system for the specialized treatment of steam generator blowdown water, designed for maximum pressure of the working fluid in the steam generators. After treatment, the blowdown water is returned to the containment building and, via the regenerative heat exchanger, to feed pipes of each steam generator. The technical result is an increase in steam generator blowdown flow, which leads to the accelerated normalization of the water chemistry conditions even in the event of significant deviations and, as a result, to an increase in the working life of each steam generator and of the steam generating plant as a whole, and also leads to a reduction in energy losses during the return of the treated blowdown water to the second loop, while at the same time rendering the system autonomous due to the absence of a link to turbine hall equipment.

Granted: 2022-10-04
Abstract: A donut-shaped component is set around an end of a pipe and both are cast into a concrete slab. Removal of the donut after the concrete has cured leaves an annular recess in the concrete slab around the pipe, which remains in the concrete. Donuts used at both ends of the pipe result in two annular recesses in the concrete, one at each end of the pipe. A cover can be used on the top donut. Further piping connections are made in the annular recesses. The use of firestopping may be avoided, and water leakage through the slab may be eliminated.
