摘要： The hinged mine stopping has at least two panels joined by a hinge defining a wall adapted for forming an air tight seal in a mine passageway to improve mine ventilation. Each panel has a lower section defined by a sheet of gas impermeable material mounted on a tubular, rectangular frame, and an upper section defined by a sheet of gas impermeable material mounted on a tubular, inverted U-shaped frame. The side members of the upper section frame telescope into the side members of the lower section frame for height adjustment of the panels. Preferably the hinged mine stopping is disposed between the ribs of a mine in a V-shape, with the apex directed towards the high pressure side to reduce the load on the stopping, the perimeter of the stopping being sealed.

摘要： Disclosed herein is a miniature, portable, self-contained power machine for handling materials, comprising, a rigid frame providing the base structure for all components of said machine, a means of electrical power supply for said machine, means for regulating the motion of said machine, two endless roller chains forming a traction system and serving as the means to move said machine over various types of terrain, means for readily receiving and rigidly securing a variety of miniature, hydraulically powered material handling implements to said machine, and a central hydraulic system which is powered by said power supply means and which supplies power to said attachable material handling implements. The machine has a diversity of applications in numerous industries. The machine accepts any of a variety of attachable implements through an assembly socket and a torque arm socket, and then links the implement to the central hydraulic system with hydraulic hoses leading to a hydraulic power manifold. Two of these implements include a telescoping boom and bucket assembly and an improved forward reach and higher lift capacity bucket assembly. A hydraulically powered dumping bed attachment may be bolted to the rigid frame of the machine and further modified to result in a hydraulically powered dumping bed and hopper attachment.

摘要： Disclosed herein is a miniature, portable, self-contained power machine for handling materials, comprising, a rigid frame providing the base structure for all components of said machine, a means of electrical power supply for said machine, means for regulating the motion of said machine, two endless belts forming a belt traction system and serving as the means to move said machine over various types of terrain, means for readily receiving and rigidly securing a variety of miniature, hydraulically powered material handling implements to said machine, and a central hydraulic system which is powered by said power supply means and which supplies power to said attachable material handling implements.
