Abstract: A mobile high horsepower rating natural gas compression package is presented. The apparatus includes a trailer having a flexible pre-cambered frame configure to absorb shock during transport and dissipate vibration during operation, and an inflexible sub-skid attached to the flexible frame. A high horsepower rating engine driven compressor is attached to the sub-skid while ancillary compression package components are attached to the flexible frame. An arrangement of break flanges is employed to permit relative motion between the compressor and the ancillary compression package components during transport and operation. The advantages are derived from a more reliable unitary mobile natural gas compression package attained through: lower transport costs and reduced transport delay, improved site access windows, lower site preparation, setup, teardown, and site reclamation costs, and reduced site preparation, setup, and teardown time delays.

Abstract: A retractable upright pole for a tent has multiple tubes receivable in one another and each tube having a ball-spring combination and multiple bores defined to correspond to the ball-spring combination of another tube to secure the connection between two adjacent tubes. The upright pole further has a chain-spring combination inside the tube to be in combination with the ball-spring combination to secure the connection between two adjacent tubes.
