A gravel packing method and apparatus are described where to set the packer; a ball is dropped to a seat that it isolated from the effects of formation pressures when trying to set the packer. This is accomplished by isolation of the gravel pack outlet port when setting the packer and locating the ball seat in a position where the effects of formation pressure are irrelevant. Additionally, by positioning the evacuation ports above a seal bore in the screen extension during circulation or squeeze to deposit gravel and further putting check valves in the evacuation ports, the evacuation step after circulation or squeeze can be accomplished without having to reposition the crossover. The crossover is supported from the packer and movement of the crossover away and back to the support from the packer operates a valve to allow squeezing when the valve is closed and circulating and reversing out when the valve is open. Thus, the gravel pack method and apparatus facilitates circulation, squeeze and reverse circulation in a single supported position.

A random rebound sports training device is provided which includes a pair of misaligned or offset net structures disposed on a frame that enable a projectile striking the net structures to rebound in a random manner. The structures are secured to a support frame such that the openings formed in the net structure, which are larger than normally utilized, are offset from one another. The offset of each of the net structures greatly reduces the potential for a projectile striking the device from contacting the same portions of the net structures, thereby causing the projectile to rebound in a random manner from the device. The frame on which the net structures are mounted can be easily configured between a use configuration and a storage configuration. Further, each of the net structures can be secured to a single support frame, or can extend from separate frames onto a target frame to provide multiple use sections on the device.

According to the construction method disclosed by the invention, a brickwork wall and a filling support are combined together, so that the construction method is simple and convenient and simple to operate and ensures that the wall body has high strength and can yield pressure suitably; and length of each walling of the wall body is consistent with the everyday propulsion degree of the stope face, and the construction method is flexibly suitable for actual mining.

The invention discloses a multi-motor joint vibration mode balancing method for a single support shafting steam turbine generator unit. At present, during on-site dynamic balancing of a single support shafting supercritical steam turbine generator unit, vibration information of two ends of rotors is not provided and shaft vibrations influence each other by coupling, so that a certain difficulty is brought into the on-site dynamic balancing of a shafting. According to the multi-rotor joint vibration mode balancing method, unbalanced types of the shafting are judged and calculated by calculating vibration vectors and vibration mode harmonic components and combining characteristics of a single supporting shafting structure according to shaft vibration magnitude values and shaft vibration phases of each rotor of the shafting at a critical rotating speed and a working rotating speed, and then a joint vibration mode of multiple rotors is identified; and a weight-increasing scheme of each plane is directly obtained according to a lag angle, mass-basis response coefficients and a first-time weight-increasing interval, and a group of increased weights are added to a related plane once. By the multi-motor joint vibration mode balancing method, the balancing efficiency and the accuracy of the single support shafting rotors are significantly increased.
