Abstract: A sliding panel includes multiple connecting/adjacent carrier tracks such as two/three/four carrier tracks while connectors of each carrier track are disposed in opposite directions or at intervals. Thus the multiple connecting/adjacent carrier tracks slide in parallel under the same channel. Moreover, the positions of each connector on top surface of respective carrier track are in alternating arrangement so as to allow runners of multiple connecting/adjacent carrier tracks being mounted inside the same channel simultaneously. The runners of the connecting/adjacent carrier tracks move inside the channel of a rail at the same time and the connecting/adjacent carrier tracks slide in parallel under the same channel. Therefore, the number of channels of the rail is decreased and the amount of material used for producing the rail is reduced. Furthermore, the rail can be designed to have two-step inner and outer rails for adjusting length of the rail.

Abstract: A hydraulic oil well pumping arrangement employs a compensating type hydraulic pump, a directional valving arrangement and a proportioning valving arrangement. When the directional valve is energized, oil is directed to the rod end of the hydraulic cylinder. The rod or piston part of the hydraulic cylinder will then elevate until a first limit switch is actuated which then will de-energize the directional valve and send a current signal to the proportional valve. This current signal to the proportional valve forces it to open to a point at which the cylinder rod would extend at the desired velocity until it reaches a second limit switch. The second limit switch is near the bottom (for example, 1 foot, or 0.30 meters) of travel of the rod or piston. The current signal to the proportional valve is then decreased, creating a choking arrangement that forces the cylinder rod to decelerate. The cylinder rod then reaches another limit switch.
